Ask The Tech Guy

Dear Tech Guy,

Could you please explain the different memories in a computer. My computer says that I still have 80% capacity left and when I try to install a program it says I don't have enough space.

Don't confuse memory (Random Access Memory), with disk space on your hard drive. RAM is the electronic computer chips that your programs are loaded into to be executed. Disk is your hard drive and floppies where all that stuff (programs, documents) gets stored when you are not using it.(Well, there is virtual memory but it isn't worth talking about now.)

If I don't have enough space I think it means on my main drive, not the memory I need to run a program or use it....

You are correct; the installer is telling you there isn't enough disk space. The install process may actually require access to some temporary space on the disk over and above the actual space required by the installed files.

I want lots of room to run my favorite programs. Maybe I am not very technical; I just want my computer to work when I need it. I am tired of these messages that say there is not enough space to install a program! What should I look for when I buy a new computer?

In my opinion (imo), you may as well figure on the following general guideline: Your computing needs will increase 100% every year for the forseeable future. While a 2 Gigabyte disk and 32 megabytes of memory may be sufficient today, it simply won't be adequate for long.

If buying a new system, get at least 32Mb memory and a 2 Gigabyte disk. Your computer will be happy and your computing experience will be much more satisfying.

Sincerely,
One very frustrated teacher
