Wireless Computing on the Go

By: Alison Brundle

Wi-Fi was probably one of the most revolutionary transitions in modern times. Before the advent of Wi-Fi or wireless computing technology, users were tethered to their desks, routing everything through a LAN line and restricted in where they used their faster and more powerful computing technology by how long their cables were. Wi-Fi changed all that. Suddenly, you had a mobile network that allowed people the freedom to roam and still connect to the Internet and their emails.

A Sociological Transformation

It is easy to underestimate the impact of wireless computing. It has become a common sight to see cafés full of people all connected up to a server, yet not a cable in sight. An entire business has grown up around wireless computing – the Internet café – that lets anyone, for a small charge, piggyback the establishment’s Wi-Fi connection and surf to their hearts content. It is even possible to connect wirelessly using a mobile phone – a situation that would have been unthinkable 25 years ago when you were lucky if you could connect to another phone number using the first mobile 'bricks’, let along the fledgling Internet.

It has released the constraints of an old system of doing business. But how does wireless computing actually work?

There are two types of what has become known as ‘wireless’ Internet – either connection through a router (your standard Wi-Fi) or through the mobile phone network. Wireless routers are the most common form of land based system, and are fundamentally a small connection box that allows a signal to be shared between several computers. Basically, computers ‘tap in’ to the signal, which can be made even easier by adding a wireless interface card. These usually come as standard with most new laptops, but can be bought as a separate add-on. USB routers and dongles also give anyone the power to be able to tap into any wireless signal, creating their own ‘access points’ through which the computer can send and receive network data.

Another key component of wireless computing is the actual hardware itself, namely the laptop. There is some contention as to who actually invented the concept of the laptop, but most cite Adam Osborne as the originator of the modern day laptop in 1981, although the ‘clam-shell’ design was attributed to William Moggridge and developed for GRiD Systems Corporation in 1979. It is difficult now to imagine life without laptops, yet it has only been a little over 30 years since their original conception. But probably the biggest influence on wireless computing was the development of WAP for mobile phones, allowing anyone to connect to the Internet using their mobile phone technology. Today, we feel short-changed if our mobile phone can’t connect to the Internet on demand, 24/7.
What future for wireless computing?

The question of wireless computing’s future is uncertain. Many believe that wireless computing has reached its full potential – we now have almost universal coverage thanks to a global satellite system creating a web across the world with very few ‘blind spots’. Smart phones are feature-rich and future-proofed to a certain extent, and laptops are smaller, lighter and more processor powerful than ever. The only area that can really see any form of development to enhance wireless computing is in the field of battery-life. The most up to date laptops and Netbooks can achieve up to nine hours on one battery, but after that you are still forced to tether up to a power source to keep your laptop running – hardly a ‘wireless’ situation by any stretch of the imagination. So for wireless computing to move to a new level and give us true autonomy and control about where and when we use our computers, manufacturers have to address the knotty problem of that infuriating ‘low battery’ symbol. Perhaps then we’ll have truly wireless computing on the go

Renting Computers and the Benefits

By: Adriana Noton

Renting computers is something that a lot of people have a lot of doubts about. Most of the time, people do not truly think about renting a computer as the computer being theirs and they do not realize any of the benefits of it. Well, that is what this article is going to explore, some of the benefits that surround renting computers and certainly how it can be used for your business or even for your home. We will also talk about how you can find a computer to rent and where you can find it.

Firstly, you need to get into your head that when you rent a computer, it is your computer for the allotted time frame that you have it. You can truly do anything you want to the computer while you have it, besides destroying it of course. You can save things to is and also use all of its features and different benefits. All of the computers that come back after being rented are reformatted, so there is no information on them.

However, if you do have a lot of information that you are saving to the computer that is sensitive and that you do not want anyone to see, you might want to use a thumb drive. This is just a quick way to transport the information from the rented computer to your own computer if you wanted.

Another benefit of renting over buying is that you do not have to worry about upgrading the computer or any of the hardware that might go inside the computer to expand the memory or the RAM. When renting, you are constantly getting the very best computer that you can get and use. That means you will never, ever have an outdated computer again, you will have the latest and greatest technology possible.

Laptops are also computers that can be rented and they are actually one of the most popular rented computers. The reason is because laptops are expensive and if you constantly have to replace your laptop, it can get costly. This is especially true if you do not use your laptop all that often, so renting is a better option a lot of the time.

Right about now, you are probably asking where you can rent yourself a computer or a laptop and that is not all that difficult to find. To be honest, many companies nowadays are offering up computer rentals because it is becoming so popular. There are also stores that are geared specifically toward the rental customer and there are many benefits of these kinds of stores.

For one, you can actually pay your computer off little by little and when you are renting computers that is an awesome benefit. A lot of rental places where you can pick up a computer allow you to pay week by week as well, so you do not have to save up a huge chunk of money at one time, which is certainly a benefit in this day and age.

The cost of computers is constantly growing and increasing, so when you are renting computers, you can pay over time, which is certainly a great benefit!

How to Find the Right Driver Download

By: Charles Carvist

Drivers are essentially a set of instructions that your computer needs to operate hardware, another description is a piece of software that determines how your computer will communicate with a device. If you are not familiar with drivers or a driver download then the following information will help you.

Most hardware devices require a driver in order to operate properly. If you buy a computer brand new, it will already have all the required hardware drivers installed, also your computer should come with a disc containing the drivers.

When you purchase a new piece of hardware, for example a sound card or a printer, it will come with a CD containing the drivers for the device. These drivers are specific to the make and model of your hardware.

Some devices do not come supplied with a driver disc, this could be because the drivers may be an intrinsic property of the device, this means any drivers required are on the hardware. An example is a mobile broadband USB stick. Once the stick is inserted into a USB port, its drivers will auto run and automatically install. It only takes a couple of clicks to confirm where you want the drivers installed, and your new device is ready for use.

Hardware like CD drives and hard drives are simple plug and play, no additional drivers are required. Some gadgets like mp3 players and cell phones come supplied with a driver disc, in many cases your mp3 player or cell phone can be used on your computer without installing any drivers. You may be limited to what functions you can perform. You will be able to perform basic operations like moving music files and pictures etc. But for more in depth activities such as synchronising your device you will need to install the drivers supplied.

There will no doubt come a time when you will need to download a driver. If you take your time to look around the internet you will probably find the driver you need for free. There are hundreds of sites that will let you download drivers for free.

But many sites out there will charge you for downloading drivers. Before paying for drivers always visit the manufacturer web site. Very often they will have drivers for all of their products available for free. When using a search engine to locate the file you want, remember to be specific in your search term. With so many drivers available and probably several different models of your device, it is very easy to download the wrong
one.

If you have exhausted every option and still cannot get your driver for free and your only option is to pay for it, then be sure it is the exact driver you need. Remember drivers are specific to the hardware, if you download the wrong one you will not get a refund, so be careful.

Some manufactures provide updated drivers for your device, these updates can come available some time after you purchased the equipment. So it is always worth checking on their web site for any driver download updates available.

A Quick Guide on it Security

By: Lorabella

We have all used the excuse of a PC crash and virus attack, perhaps even more than its fair share to avoid working, giving in projects on time and missing deadlines. Many a times it is really just an excuse, but for many, it has posed actual problems causing loss of important and often irreplaceable data. How many times have you wanted to kick yourself for not bothering to get a good anti-virus, anti-spyware and firewall because thanks to it you ended up re-doing presentations. And doesn’t the loss of all your favourite videos, the pictures of your last holiday, and your best songs stored on your PC, make you wish that you had been more careful, and at least made back-ups? And if all this sounds familiar to you, and brings back unpleasant memories of computer crashes or irritating pop-ups or worse, your email and Facebook accounts being hacked, then it is time to sit up and pay attention.

The world of IT security has many dedicated professionals who work on developing new and safer anti-virus, anti-spyware, pop-up blockers and other software to protect your PC from hacking, virus attacks and in the worst case scenario - crashes. The importance of IT security has been acknowledged by one and all today. If you believe that only government or top-secret websites, or those who use net-banking and online purchase facilities need good IT security software, then it is time for a reality check. Don’t we all get spam mail all the time, and often, even if advertently end up clicking on some random link, or visiting potentially damaging sites and put our PCs to risk? It is not only people who give out personal information like credit card numbers, or bank account numbers online who need IT security, but anybody and everybody who has access to a PC with Internet. Spyware, malware and viruses are all risks that plague every PC, and often without even us knowing about them.

Many of us avoid buying original and authentic anti-virus and spyware programs, and try and make do with the free, easy to download versions online. However, what we forget is that these are generally trial versions that offer to scan your PC and alert you about potential threats but do not in any way get rid of them. Though buying an anti-virus CD will make you shell out a few bucks, but it is definitely worth the effort. The surety that you will not face computer crashes that are almost a matter of life and death for many, and have your personal emails hacked is worth each and every penny. With so many anti-virus and anti-spywares available today, there is really no excuse if you still end up having IT security issues.

Investing in a good and safe anti-virus would be the first step if you want to make your PC safe and secure against potential IT security issues. Anti-Spyware and malware lodge themselves in your PC and monitor your online activities and give away important personal information to hackers. In fact, not bothering about IT security is tantamount to throwing the field open for hackers to hack your emails and accounts. Pop-ups, are again something we all agree are irritating beyond a shred of doubt, but more than just that they are links to potentially damaging sites and spyware and an open invitation to security problems. A good pop-up blocker, available online (most of them are free of cost) would also be a wise decision.

The world of IT security offers solutions to all your PC safety and security problems, and to think that you could be least bothered by it is the worst thing you could do to your PC and your online activities.

Maintenance Tips For Your Computer

By: Jane Michael

Anybody who knows computers knows how quick one model can become outdated and how troublesome that can be if you use your computer on a fairly constant basis but an outdated computer is not the only problem that can cause your computer to run badly. That is the thing with computers, you could have a slow running computer or a problem with a particular program and there could be a million and one different problems with it.

Difference Between Onsite and Offsite Storage

By: Gail Dixon

Onsite storage simply means storing your critical data periodically or progressively over local storage media such as hard disks, DVDs or CDs. Offsite storage, on the other hand, stores data onto a remote server typically connected through the internet. Although both methods are commonly used in the industry yet there are some vital differences between the two that can help you determine which one to use under which circumstances.

DVD backup is an onsite backup term used to describe the process of backing up the data from a hard disk onto a DVD. The DVD backup is better as compared to CD backups. CDs can hold only 750 MB of data while atypical DVD can hold 4.7 GB of data. DVDs having a capacity of 8 GB are also available in the market. When buying DVDs for your DVD backup system, it is important to check the compatibility of the system where these DVDs will be used. If your DVDs are incompatible with the underlying system, you may not be able to backup or restore data with ease.

Blu-Ray DVDs are a latest addition to the DVD backup system. A single Blu-Ray DVD can hold up to 27 GB of data onto a single disk. Blu-Ray DVDs have eased the data backup processes but recovering 27 GB of data from a single disk can be really daunting especially in the absence of software to facilitate the process. However, unlike CDs, DVDs are faster and provide multiple recording sessions on the single disk. DVD backup has certain disadvantages. If you place your backup DVDs on-site with the source computers, you will not be able to save any of them in the event of a natural disaster. With an increase in the data, DVDs get piled up and become difficult to manage.

Cost

One of the major differences is of cost. Onsite data backup may cost in terms of software license and fees but on an ongoing basis, the overall cost is substantially reduced as only the storage media is to be purchased. Offsite data backup involves a 3rd party server and bandwidth costs. If your company’s data is huge, the remote storage and bandwidth costs actually cost a lot which can make you think twice before selecting a remote backup.

Performance

The performance of an onsite storage and recovery is much faster as compared to offsite backup system. When you share backup your data using a disk drive, CDS or DVDs you actually are doing it much faster as compared to storing it offsite. The same is with the recovery process which again involves internet and special remote client software. There is a considerable network delay as well in the case of offsite back up which is not an issue with the onsite data backup and recovery.

Security

As a general rule, the backup data and the original source should not be at the same physical location. If you use CDs, DVDs or had disks to store your data, you should store them at another location. This is not a problem with the offsite data backups because they are already stored offsite and often replicated to ensure maximum data security. The data in a remote storage is encrypted too. It hampers performance but it is more secure as compared to onsite data storage and backup.

There are many companies in the UK that can provide professional backup solutions to companies and organisations in the UK. You have to perform an exhaustive search to look for any such company but alternatively, you can contact Quote Bean to locate any such companies and get free quotes.

How I Sped up my Personal Computer in Three Smooth Steps

By: Mark Berns

To accelerate your Windows, you don't have to buy and set up some other computer hardware. Really - if you had your computer for some time, you can do a lot by merely installing software and using it on your computer. In this article I tell you, how I speeded up my computer this way. After I used my own advice, my computer speed enhanced by 43.2%.

I don’t know about you people, but one day I observed, that my computer is becoming slower and slower with each day. At first I reinstalled Windows and erased my hard drive every time I felt it was too sluggish. But with time I did a research to pick up, that there are more effective ways. There indeed are a couple of effortless things that I could perform to sped up my computer.

Here they are:

-Clean up Windows Registry. Making clean Windows registry can take your computer up to 50% faster!

-Get ridded of what computer software you don’t want. Your computer arrives to you with flocks of pre-installed trial run computer software, most of which you don’t need. Make it go away.

-Get rid of fancy visual effects.

Cleaning up Windows registry

When I was screening registry cleaners, I marked a problem – some of them just broke my Windows, or made it function improperly. Afterwards – when I was making my web site, devoted to raising Windows speed, I formulated great test, to which I submitted 41 different registry cleaners. I utilized the registry cleaners at their upper limit, and than observed the resulting impact on my computer. After the testing i realized, that solely 7 of those registry cleaners are of any use, and by that, I mean, that they do not harm your operating system, and that they give you sizeable (surpassing several %) performance hike.

Supported by my tests, I gave voice to few recommendations for you to deliberate, when seeking a respectable registry cleaners:

-Use exclusively best-selling registry cleaners. As I've seen, there are rational reasons, why nearly all registry cleaners aren’t popular

-Always back up your operating system before trying a novel registry cleaner. It turns out, that for each PC, Windows registry is unique. What works on one PC, may not work decent on some other. This means – what worked for your friend, may not work for you! You have to always test registry cleaner on different mashines to discover , if it is any good.

Uninstalling computer software

Sometimes computer software package simply refuses to get uninstalled, or there are uninstallation computer errors etc. This problem can be actually fixed. There are several software packages, which can help you completely deinstalle software from your Windows.

Visual effects

So far, each Windows operating system – taking out, may be, Windows 7, came with fancier and fancier visual effects, which induce your Windows to get slower. You should know, that those effects can be disabled. And – if you choose to do so, your PC may start operating significantly quicker. Of course, it depends on your preferences. I understand, that working on a fine looking PC experiences better than working on a Windows with every visual effect stripped down. Some of my co-workers opt to work with Windows 2000-like user interface, in Windows XP though, but by and large that’s too radical. Great news is, that you can gain a lot of speed advantage by disabling some very fancy but barely visible visual effects in Windows.

Should I Replace Or Upgrade My Personal Computer

By: Alison Brundle

If your PC is getting a bit long in the tooth, the temptation to replace it with a newer model is always there. The very latest in top-spec laptops, Notebooks, PCs and computers are constantly advertised and the pressure to buy the latest model is intense. The price of new technology is far lower proportionally than when computers first became a common household addition, but do you actually need to replace your entire system or can you save yourself time and money by upgrading what you already have?

The question you have to ask yourself is: does my current computer do everything I want it to do? If the answer to that is yes, then your current system will probably be sufficient for some time to come. But if you are determined to upgrade, then you don't have to replace the entire system to enhance its capabilities - you can upgrade areas of your existing hardware for a fraction of the cost.

The monitor

Old computer monitors are cumbersome, energy-greedy and have a limited lifespan. The easiest way to upgrade your set-up is to start with the monitor. Flat screens take up far less desk space, are higher resolution (meaning far better picture quality) and modern LED screens are also much more energy efficient. The old monitor can be consigned to the recycling centre and a sleeker, more efficient flat screen is the quickest way to upgrade your set-up for a fraction of the cost of a new computer system.

RAM memory

The more RAM you have, the faster your PC will run. Applications use the RAM memory to run and the operating system uses it to ensure that applications work correctly. RAM is an add-on that is simple to install and relatively cheap. However, different machines take different types of RAM so contact a manufacturer and they will be able to tell you which RAM you need simply from the make and model number of your PC.

Storage

Hard disks have a finite amount of storage space available, so updating your storage system can free up your computer's hard drive. A remote hard drive is also an excellent way of keeping all your data and information safe, enabling you to restore your computer to full working capacity in the event of a catastrophic hard drive failure such as a virus attack or mother-board problem. Files such as films, music and other downloads take up a great deal of storage space so downloading these onto a remote hard drive is a great way of freeing up your computer's disk space and helping it to run more quickly.

Graphics

Graphics cards are easily replaced. These plug-ins power the display and the faster and more capable your graphics card, the sharper and clearer your images will be. This is particularly useful if you are into computer games, as the graphics in modern games are exceptionally sophisticated and require high-resolution graphics.

Processing power

Your processor is the heart of the computer. This determines the speed that your computer operates at and replacing it can be a complex task, so only attempt it if you are absolutely sure you know what you are doing. You may also need some specialist equipment and to be sure that the processor you wish to insert is compatible with your system so if you do decide to upgrade your processing power, it is best to talk to an IT expert first.

You can also upgrade your current PC by adding USB ports, network cards or modems is all relatively easy to do by simply opening the casing of the unit and inserting the cards into the PCI slots. Upgrading your computer is one of the simplest and cheapest ways of increasing the speed and capability of your computer without having to throw the entire system away and buy a new one.

There is also the problem that your new computer may have trouble recognising all of your old data from your previous machine, making data transference difficult and frustrating. So is it better to stick with the devil you know? Modern computers are adaptable and easily upgraded. Whilst you don't always need to be at the cutting edge of technology, it's wise to consider at least one upgrade in every computer's life. If you've reached the limits of your current computer's capacity, then perhaps that is the time to think about finally replacing it for a newer model.

Buying a Computer Online

By: Amy E Nutt

Buying a computer can be a tricky prospect because there are so many things to consider before making the final purchase. You have to take into account how quickly technology changes and decide what you’ll need to satisfy your computer needs for a few years. There are also some computers that are easier to upgrade than others which could factor into your overall decision. On top of the already confusing decisions, there are a lot of technical terms that explain how a computer works and if you don’t know what they mean you could have no idea what you are buying. Shopping online for your new computer can help make things a lot simpler.

Most computer manufacturers have set up websites that make searching through their products easier than ever. You can decide whether you want a desktop or laptop and even choose from a list of possible things you will be using your computer for to narrow down your search. The options are usually casual computer use, work, and gaming and selecting from those choices will give you a list of computers that will already have the right components in them to do what you want to do. As an example, a gaming computer will have a better than average graphics card and more RAM, both of which are needed to play games.

Shopping for a computer online also gives you more personalized customization. You can choose the color of your computer, although some websites will give you more options than others. You can also upgrade the components yourself so that you get exactly what you want. Most manufacturers will have steps through the possible upgrades directing you to the part of the computer that can be upgraded and what options they have for it. You may even be able to get software pre-installed on your computer from programs like Photoshop to the latest Call of Duty game.

Customer support is also an added benefit of buying a computer online. Unlike going to a store where you may have to compete to get the attention of one of the employees, websites have multiple people online and ready to help you with any questions you might have about your new computer purchase. Often the customer support will be available as a chat window that you can look at while going to different sections of the website, making it possible for you to discuss specific things about what you are looking at.

Every website that sells computers has specials going on all the time and you can take advantage of the ones that work for you. Usually they are discounts or free items such as a printer when you buy a certain model computer. Since most of the models are upgradeable then you will be sure to get a good deal. Once you’ve got everything you need in your cart you can pay online with your credit card through a secure area and have your computer shipped right to your door in as little as a few days.

Who Are the People That Need Computer Rental

By: Amy Nut

To the average computer user, renting a computer seems a little strange. Why wouldn't you want to own the machine? To the average household, renting a computer does not make much sense, but there are some organizations and individuals who can stand to save a lot of money with this option.

Entrepreneurs

The entrepreneurial among us often find the cost of starting their new enterprises to be the main thing that holds them back. One of the biggest costs associated with starting a new business venture is the cost of technology. Computers are not cheap.

Those interested in starting a new business but lacking the resources to purchase new technology can rent some instead. Once the business is up and running, bringing in income, they can start setting money aside to purchase their own equipment. This ensures that the business starts with excellent, up-to-date equipment, rather than the old computer the entrepreneur has been using at home.

Conference Speakers

Those who frequently travel to speak at conferences and seminars find the hassle of bringing their own computers with them to be too much to deal with. Not only do they have the added time it takes to get through security, but they also have the risk of theft, damage, or loss of their valuable equipment. Sometimes the seminar is best serviced by offering computers to the listeners as well as the presenter. Carting that many computers through an airport is almost impossible.

Computer rental gives these individuals the best solution. They can bring their presentation on CDROM, leaving the computer behind. When they arrive at the conference venue, the computer equipment they need will be waiting for them, set up, and ready to use. All they have to do is stick their disc in and they can start their presentation.

Trade Show Presenters

Those who frequently set up booths at trade shows can also benefit from computer rental. Like the conference presenter, trade show presenters struggle to carry computer equipment on the airplane or bus as they travel. Depending on the type of booth they set up, they may want additional upgrades like huge wide-screen monitors and extra computers for potential customers to use, and transporting these items without damage is almost impossible. A computer rental company can have the necessary equipment ready for the presenter when he arrives at the trade show venue.

Individuals Facing a Transition Time

Are you moving soon? Are you about to end one chapter of your life and start another? If you do not already have a computer, but wish to get one soon, renting during this transition time might be the best option. You will have access to word processing programs to brush up your resume and cover letter, the Internet to look for jobs, and email to keep others in the know about what is going on in your life, but you will not have to fork out hundreds of dollars to purchase a machine. When you are in a more settled position, you can look to buy that computer.

Computer rental is ideal for people who have a temporary need for quality computer equipment, either when traveling, in a transition period, or starting up a new business, but do not have the collateral necessary to buy a new machine. If you are in one of these situations, consider renting a computer.
