What id GB in computer terms?
Gigabytes. There are 1024 Megabytes in one gb. It depends in what way you want to reduce the usage. If you’re talking about storage, there are a few things you can do, such as running Ccleaner, and the Disk Cleanup utility (which can be found in Start > All Programs > Accessories > System Tools). For the latter once you’ve run it, click the More Options tab and delete all your unused restore points. Last time I did that I cleared up 35gb! If you’re talking about RAM, you should try to keep open only essential programs to free up space and this’ll also improve performance. It’s a good idea to go to Start > Run “msconfig” and go to the startup tab. Here you can chose which programs you want to run upon Windows startup. The fewer programs the quicker your PC will be ready to use and the faster it’ll run. I hope this helps.
