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 th
e 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.
