- Memory is one of the most important feature of a computer
- A bit is a binary digit that can have the value 0 or 1
- A byte is defined as 8 bits
- A nibble is half a byte, or 4 bits
- A word is two bytes, or 16 bits
- A kilobyte is 210 bytes, or 1024 bytes
- A megabyte is 220 bytes, or 1024 kilobytes
- A gigabyte is 230 bytes, or 1024 megabytes

- RAM and ROM are the types of memory commonly used in computer
- RAM stands for Random Access Memory

- RAM and ROM memories are referred to as primary memory
- A memory chip contains 2x locations, where x is the number of address pins
- Each location contains y bits, where y is the number of data pins on the chip
- The entire chip will contain 2x * y bits, where x is the number of address pins and y is the number of data pins on the chip
