When downloading files from the Internet you will often get an archive. The purpose of an archive among many is to reduce download size, reduce the number of files being downloaded to just one, provide a basic integrity check on the subject files, and sometimes provide additional security with the use of passwords. There are many archive types most commonly used of them are .zip, .rar. .7z, .tar.gz. Today we are going to speak about .zip archives. On Windows, there exist GUI archivers like WinZip, 7zip, or WinRAR, which are able to deal with most of the common archive types. Ubuntu Linux has a built-in Archive Manager that can be invoked by double-clicking on the .zip file in a GUI.

This type of utility lets users compress, decompress, and archive files and directories. Most archivers also store additional metadata such as user and group permissions, timestamps, and directory structures. Other features often found in archive managers include support for multiple volumes, encryption, Unicode names, password protection, and integration into the shell.

The HP Business Desktop systems provide a BIOS upgrade option through both the Startup Menu and the F10 Setup utility using the "Flash System ROM" feature. Reboot the PC and press the Escape key to display the Startup Menu. Use the arrow keys to select Utilities, and then select the Flash System ROM option. Alternatively, reboot the PC and press F10 to access the BIOS Setup utility. In the File menu, select Flash System ROM. Either method requires that removable media be present (USB storage or data CD) that contains the BIOS binary image file in the root directory. The binary image file can be found in the DOS Flash folder and is named xxx_MMmm.bin where "xxx" is the BIOS family, "MM" is the major version number, and "mm" is the minor version number. To create a CD for updating the BIOS, use a blank CD-R or CD-RW disk on a system with a CD-RW or DVD+RW drive, and write the binary to the disk using any CD-burning software (Windows 7 and Vista support burning data CDs without additional software). If a BIOS Setup password has been set, the password will be required before being able to access the "Flash System ROM" menu. The user is notified when the process is completed. The new BIOS code will not take effect until the PC is restarted. 2ff7e9595c
