Most Commonly Used IT Acronyms and Their Meanings

CPU (Central Processing Unit)
The CPU is the computer ‘brain’ and its most important element. It interprets and executes most of the commands from the computer’s hardware and software.

RAM (Random Access Memory)
RAM may be compared to a person’s short-term memory. It is the place where the operating system, application programs and data in current use are kept so they can quickly be reached by the processor.

GHZ (Gigahertz)
GHz describes the frequency cycles and is used when discussing computer performance, usually the clock speed of the CPU. A CPU with a higher clock speed can process data faster. One GHz means 1 billion cycles per second.
A gigabyte (GB) is equal to approximately a billion bytes and is a measure of computer storage capacity that could be used to describe disk space, data storage space, or system memory.

A megabyte (MB) is a measure of computer storage capacity and is equal to approximately a million bytes. Most PCs have storage in gigabytes, not megabytes.
