In these days of extra large hard disks many try to copy huge files from a DVD/CD but find that can not even though there is plenty of free space on the hard disk. The most likely cause for this is not some sort of copy protection but that the file being copied is too large for the file system to handle. Microsoft Windows 8 allows you to format a hard disk in two different file system formats: FAT32 and NTFS. These file systems differ in the size of file they can handle. FAT32, for example, can only handle files up to ~4GB in size. When it was developed, that size file was almost unheard of but now, a DVD can have files that large or larger routinely. So, if you are trying to copy a movie from a DVD onto your FAT32-formatted hard drive it likely won’t copy as most full-length movies are files larger than 4 gigabyte.
What Is a Country Codes And Domains? (© All Computer Studies)
The last characters on a domain name are usually known as country code (e.g., .pk, .in, etc.) or a top level domain (e.g., .com, .org, etc.).
Domain names around the world often have a country code associated with them. The links are to the latest WHO is information for the top level domain.
Learn About How Do I Remove Add/Remove Programs? (© All Computer Studies)
Generally, you would use the Window's Control Panel’s ----> Add/Remove Programs tool or Vista's Default Programs | Programs and Features page to install/uninstall programs from your laptop computer. Some of these uninstalls will leave program names behind which, when clicked on it, either produce errors or no result. You can remove these invalid entries using these steps carefully.
Start the Registry Editor (Start ---> Run and then type “regedit” [without quotes] into the textbox)
Go to this key value in the left panel:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Right click on the Uninstall entry. Select the 'Export' option from the left menubar. Give the exported .reg file a name you can remember and store it in a location you can remember. Doing this makes a backup you can recover from if you make an editing error in the steps below.
* Locate the specific key you wish to remove. It will likely have the name of the program but, in case not, scroll down each entry and look at the value for DisplayName. The key you want is the key that contains the same display name as you are trying to remove from the Add Programs menu.
If you want to be extra safe, right click on this key and again select Export and save the .REG file.
* Close the Registry Editor.
* Open the Add/Remove Programs utility from the Control Panel and verify that the invalid entry is gone and that the other entries are still there.

What Is Computer Virus? (© All Computer Studies)
A virus is a program that produces its own language by attaching its self to other executable files (.exe) in such a way that the virus code word is executed when the infected executable file is executed. There are a large number of virus types. A virus reproduces, usually with out your permission or information. In general terms they have an injection phase where they produce widely and an attack phase where they do whatever damage they are manage to do.
Another way of looking at viruses is to consider them to be programs written to create copies of themselves. These programs attach these copies onto host programs . When one of these hosts is executed, the virus code executes, and links copies of itself to even more hosts.
Similar to viruses, you can also find malicious code in Trojan Horses, logic bombs. Often the characteristics of both a virus and a worm can be found in the same beast confusing the issue even further.
An famous example of an executable file would be a program (.COM or .EXE file) or an overlay or library file used by an .EXE file. But just as critical, would be the macro portion of what you might generally consider to be a huge data file (e.g. a M.S Word document). It’s important to also realize that the system sectors on either a floppy or hard disk contain executable code that can be infected even those on a data hard disk. More recently, code written for Internet Web sites included in Electronic mail can also be executed and infected.
