The need for a home computer has become a real necessity. So if we do not want to invest too much in buying the best computer there is today since all we want is a computer that will enable us to connect to the internet and enjoy the enormous public library of information that there is out there, we can invest on a simple computer at a very low price.

As computers have advanced and there are so many of them out there, with different configurations for different purposes, we can find a computer that suits only the things we need, only the things we define we want the computer to do. There are many second-hand computers out there at people who might want to upgrade to a newer faster computer, but their old computer might have all of the qualifications you need for simple use.

Since the computer designers know that there is a need for simple computers at cost-effective prices, they design computers in a way that enables them to save production costs and produce a computer package that can be sold at lower prices. There are laptops that are cheaper than other laptops, since they are used for the audiences who need simple tasks, without sophisticated applications that require a lot of resources to be able to run properly. The simple tasks require very little. Even old computers can surf the internet, it is all about our choice, what do we need and how much do we want to pay for it.

So how can we find cheap computers? Well, we just need to decide first if we want a new computer or a used one. We can find on the internet many used computer ads, that offer second-hand computers, and there are many good offers there, from people that took great care of their home computers, and they just want to move forward to new computers, maybe for their kids game playing desire or just to be able to run more sophisticated resource-consuming applications that they need (like graphical designing programs).

We can find cheap laptop computers, like the 10 Inch laptops, that have been produced lately and mostly for students, who need low weight, small-sized laptops to be able to type the lectures, or any other information during a lesson. Those are cost-effective and have the basic needs for such tasks.

Just inquire for a computer after you have defined your needs, and you will be able to get a price offer for a computer that is cost-effective for your demands, at the best cost, since it will have only what you really need.

We always want to be in control and some of us have information at home that we might want to be able to access remotely. Accessing the home computer remotely means that you connecting to the internet and want to be able to access your home computer and perform certain operations. Those types of operations have some effect on which tool to use since some of the tools enable a certain type of access and some take control of your own computer, so you could see the same screen of your home computer as if you are standing in front of your computer.

There are certain security measures that need to be understood. When we open access from the outside to our computer we actually open a door for someone (hacker) to access our computer, or to be able to do so. If the door would be closed and shut with a brick of the wall, then it is closed. But if we decide to make an opening, an external person can reach that opening, and might, of course, use it to do some harm, see our materials (in case they are confident – it might be risky) or spy on our actions, and maybe if we do not pay attention to see some important information like when we log-in to our bank account from home or place a credit card number on an online website to purchase something. If your computer is breached all of those actions and more can happen to your home computer.

The remote access tools are being divided to online programs, software programs. The online programs are programs which are using internet technology to enable the remote connection like the LogMeIn, GoToMyPC, TEAMVIEWER, WEBEX PCNOW, some of the support people use WEBEX technique to gain access to your computer, seeing your screen, with your permission of course (you initiate the session) and you can see everything the support person does on your computer. The software programs are tools that open access and enable the end-user (remote person) to take control of your home computer. Some of these programs are TightVNC, RealVNC, Symantec PCAnywhere, LAPLINK and there is a built-in application in Windows XP, called remote desktop (you can run it by typing on the start–>run MSTSC).

Some programs might require you to set a permanent IP (called Static IP), which means that you will need to ask your ISP for a permanent IP to your computer. The ISP will give you an IP, and you will need to configure your home computer’s firewall NAT (network address translation) which means you will have an internal IP translated to the IP the ISP gave you. The only IP a remote person (or anyone outside of your home) will be the ISP IP, which protects your internal IP (no one will know what your internal IP is they will only know the external IP that you set on your home computer firewall. That IP directs to your computer, and so there is a way to access it, with the correct tools, and of course only by knowing the access password.
