Difference between direct and serial access?

Serial access means going through everything one by one, starting at the beginning, until you reach the item you want. Direct access means going straight to the item you want without having to go through other ones. If you wanted to print all the names in a database, using serial access would be fine because you are starting at the first and going right through to the end.

In terms of storage units, magnetic tape is a form of serial access, where a disk provides direct access.

What does 15a 250vac mean?

It is the rating of an electrical appliance. In this case it would apply to a fuse or a switch.

15A means 15 Amps and it is the amount of current that the device can handle being drawn through it.

250vac, means 250 volts alternating current. The device has been designed for use with mains voltage at a maximum of 250volts and is designed to be used with AC, alternating current from a domestic supply outlet.

Switch gear designed for DC has to be fast acting to prevent arcing. AC alternates and so transitions through zero, thus breaking the arc sooner.

Importance of computer to mass communication?
