Updating computer memory datingboom
An example of a software upgrade is upgrading your version of Windows.For example, if you had Microsoft Windows XP and upgraded to Windows 7, it would be considered a software upgrade.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.In an average computer, it takes the CPU approximately 200ns (nanoseconds) to access RAM compared to 12,000,000ns to access the hard drive.To put this into perspective, this is equivalent to what's normally a 3 1/2 minute task taking 4 1/2 months to complete!All the present operating systems work with the multitask concept, where we can run more than one program at once.
If there isn't enough room in memory for all the information the CPU needs, the computer has to set up what's known as a virtual memory file.Occasionally, a computer will need to have its BIOS updated. As new devices and standards arise, the BIOS needs to change in order to understand the new hardware.Since the BIOS is stored in some form of ROM, changing it is a bit harder than upgrading most other types of software.Upgrading the computer all depends on the type of computer you have and what you hope to achieve with the upgrade.For example, the most common upgrade to a computer is upgrading the computer memory to achieve better performance and greater memory capacity.
Then go to the BIOS manufacturer's Web site to see if an upgrade is available.
