It is called a block (or sector). The size of the block varies depending upon the size of the disk, advanced preferences (the size of files normally being used on that disk), and the filesystem being used.

What are the statistics of a computer getting infected by a virus?
40% of computer users have been infected by a virus.
For a computer application to be called a virus, it must do several things.
Most importantly, it must be able to copy itself into the computer in such a way that the copies can also copy themselves into the computer as well.
After a computer virus is able to spread, the virus programer is able to do other activities depending on his own goals. He might want to have your computer send emails to everyone in your address book. He might want to detect passwords and send the passwords back to himself. He might want to damage the computer in some way by writing damaging code into the operating system or onto the directory of the hard drive.
The most common way that computer viruses attack computer programs is by adding the virus code onto the end of the program so that each time the program is run, the virus code is run as well. The original program might be the operating system or some other application.
When the computer is busy running the virus code, it may not run the original program, or it may cause so much activity that the whole computer slows down or crashes.

How does a computer virus attack to your computer?
Computer viruses are mysterious and grab our attention. On the one hand, viruses show us how vulnerable we are. A properly engineered virus can have an amazing effect on the worldwide Internet. On the other hand, they show how sophisticated and interconnected human beings have become.
When you listen to the news, you hear about many different forms of electronic infection. The most common are:
Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs).
E-mail viruses - An e-mail virus moves around in e-mail messages and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.
Worms - A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.
Trojan horses - A Trojan horse is simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your HDD). Trojan horses have no way to replicate automatically.

How do you hide folders in windows7?
add a $ after the folder name to access the folder map a network drive and use the folder name with the $ Note: If you want to can not see share folder all user. user view only his folder then you can configure Dfs. Methode: Start > Programs > Administrative Tools > Distributed File System or in the Control Panel, open the Administrative Tools folder and click on the Distributed File System icon. This will open the management console where all the configuration takes place.
The first thing you need to do is create a root. To do this, right click the node and select New Root.
Press next on the first window to be brought to the screen where you will have to make the choice of creating either a stand alone or domain root. A domain root will publish itself in Active Directory and supports replication, whereas a stand alone root does not. If you have an AD Domain Controller set up on your machine, I recommend choosing the domain root.
Note: The root would be the top level of the hierarchy. It is the main Active Directory container that holds Dfs links to shared folders in a domain. Windows 2003 allows your server to have more than one root - which wasn't the case in Windows 2000.
The next screen is the one where you have to select which trusted domains will be hosted. Since I only have one domain in my network, only domain.com is visible.
Once this is done you have to select a server on that domain - in my example it is netserv. The FQDN (Fully Qualified Domain Name) of this host server is netserv.domain.com. Start > Programs > Administrative Tools > Distributed File System or in the Control Panel, open the Administrative Tools folder and click on the Distributed File System icon. This will open the management console where all the configuration takes place.

Why do digital computers use binary numbers for their operation?
Digital computers use binary numbers because that is easier for them, and the easiest way for humans to represent what goes on inside of computers. Computers contain millions of transistors inside the various ICs in the computer. Transistors can generally be on or off. Sure, it is possible for transistors to have a range, but then, in this case, it wouldn't be digital. So since the transistors are used as on-off switches, it is easiest to represent them as binary digits, since they can either be on or off.
