CHAPTER 3—Computer Memory
Recall from chapter one that
the major hardware components of a computer system are:
- Main memory
- Secondary memory devices
- Input/output devices
This chapter looks at main and secondary memory.
- Bits and Bytes.
- Kilobytes, megabytes, gigabytes.
- Main memory and addresses.
- Secondary memory.
(Educated Guess: ) If you bought a new computer,
about how much main memory would you
expect it to have: 128 bytes, 64 kilobytes, 4 megabytes, or 64 megabytes?
(Hint: Encarta (a multimedia encyclopedia) needs a minimum of 16 megabytes.)
