Updating computer memory

In so doing, the CPU reserves space on the hard disk to simulate additional RAM.

This process, referred to as "swapping", slows the system down.

Sometimes the utility and update are combined in a single file to download.

Copy the program, along with the BIOS update, onto a floppy disk.

For most software programs, this is not a problem as long as you no longer need support from the developer. However, if you had Windows 7 and needed to install fixes for security vulnerabilities or other problems you would "update" Windows.

However, for operating systems and software programs that could have potential security vulnerabilities, not upgrading may leave your computer vulnerable to attacks. See the update definition for information on this term.

As with changes to the CMOS Setup, be careful when upgrading your BIOS.

Make sure you are upgrading to a version that is compatible with your computer system.

You can, for example, have a word processor and a spreadsheet open ("loaded") at the same time in the RAM memory.

To change the BIOS itself, you'll probably need a special program from the computer or BIOS manufacturer.

Look at the BIOS revision and date information displayed on system startup or check with your computer manufacturer to find out what type of BIOS you have.

Almost all software developers will release software updates to help keep a program secure and stable.

However, eventually, all companies will stop supporting a program after upgrades to a program are released. For example, if you have Windows XP and want Windows 7 you would "upgrade" to Windows 7.
