Hardware & Software Needs

Do I need my own computer?
o No, but it is more convenient for you

If I have my own computer, can I use it?
o Sure, but you will using it mostly to login to
your GL account or for word processing

Do I need a C Compiler?
o No, and if you buy one, you may be
wasting your $$$. All programming should
be done in your GL account.
