While watching the first few class videos I learned so much about the workings of a computer and how it all comes together. I found RAM of special interest because I have a very sluggish computer system which appears to become more so as time goes on. I assumed the only solution would be to soon put out big bucks for an entire new computer system. But as I researched more about RAM, I found that this is a fairly simple, and in comparison, inexpensive way to upgrade and possibly make my system run faster.
When I accessed the Indiana University Knowledge Base website I learned the following about RAM. These memory chips provide space for your computer to read and write data to be accessed by the central processing unit (CPU). Memory stored in RAM can be accessed much more rapidly than when the computer has to go to the hard drive to find it and sort it out. The programs you are working on at the time are brought from the hard drive to the RAM chips. As you open more applications or programs the RAM memory will become full and the computer will then have to go to the hard drive to access the program you are requesting. This slows your system down. So, obviously, the more RAM you have available, the faster your computer should run.
Also of interest, I learned that data stored in RAM stays there only as long as your computer is running. As soon as you turn the computer off, the data stored in RAM disappears. When your computer reboots, it accesses the read only memory (ROM) chips and loads the more recent information back into your RAM.
Please watch this brief video to learn how simple it is to add RAM to your desk top computer.
