Quiz 1 Key (Week 2)

Each question is worth the same amount.

 

  1. Name or describe five major subsystems included in a typical personal computer.

 

Any combination of the following (10 points each): CPU/FPU, memory (RAM, ROM), mass storage (Hard disk, floppy disk, CDR, DVD, etc.), electronic I/O devices (NIC, modem, USB), user I/O devices (keyboard, mouse, screen, printers).

 

  1. Explain the difference between interactive and batch mode programs.

 

Interactive programs require user input while they run. Examples include word processors, spreadsheets).

 

Batch programs do not require user input and can run unattended. Examples included simulation and billing programs. Data for batch programs generally come from and/or are sent to disk files. The data generally is not in the program itself (that would be a poor design).
