Study Notes

CPU Speed Measurement

CPU speed is measured by the frequency at which it executes instructions.
Clock speed is the frequency at which instructions are executed.
1 GHz = 1 Billion cycles per second.
1 MHz = 1 Million cycles per second.
1 Hz = 1 Cycle per second.

Data Units

Bit: The smallest unit of information.
Byte: Represents a single character.

Memory Types

ROM (Read-Only Memory): The contents of ROM are fixed during operation. You cannot write to this type of memory.
RAM (Random Access Memory): The contents of RAM are changeable during operation. The operating system refreshes RAM when the PC is on.
NUM: The operations completed when the PC is turned on. (Note: "NUM" likely refers to "NUMA" or "Non-Uniform Memory Access", which describes a memory architecture, not a type of memory itself)
