Each 'switch' is described as a BIT. In order to pass information more quickly, the computer looks at more than one BIT at a time.

I hope you enjoy your visit to my site. I have used a TI/4A since , and it is really a great computer. It still has a substantial following, and I still use mine to this day. I hope you find something useful and interesting on these pages. Feel free to sign or just visit the guest book. You may just recognize some names from the past!
