Computer – units of measurement
Memory capacity and data storage capacity for computers are measured in bytes. File sizes are also measure in bytes (one byte is 8 bits). However, a byte is small (it can hold only one character) so we use larger units:
Computer - speed measurement
- How speed is measured :
In computing, most central processing units (CPU) are labeled in terms of their clock rate expressed in megahertz or gigahertz. Hertz has become the primary unit of measurement accepted by the general populace to determine the performance of a CPU. For home-based personal computers, CPU clock speeds have ranged from approximately 1 megahertz in the late 1970s (Atari, Commodore, Apple computers) to up to 6 GHz in IBM POWER processors. The abbreviation MHz is short for megahertz. Megahertz is a measurement for one million cycles every single second. MHz is pretty common terminology when we talk about computer processor speed.
