What Is The Relevance Of Computer In Today's Age?

Computers are in all aspects of our lives these days. They help to operate and monitor large industrial plants, used to diagnose auto problems, heck there are computer boards right in dash nowadays. As well as instant information, make the post office almost obsolete. Mind you they raise prices to make up for loss of correspondance. Hate that, but even they have computerized weight machines to determine price of parcel. It is used in banking, can pay bills instantly, print out statement, also, filing taxes get to track return if one coming. My goodness, computers are now everywhere. I remember when information sharing was typing on a dark screen with green letters, then mailing the floppy disk to someone for them to get the information.
