Glossary Term: GHz

Definition. GHz, short for gigahertz, is a unit of frequency equal to one billion hertz. It is commonly used to measure computer processing speed, alternating current, and electromagnetic (EM) frequencies.

What is the difference between DRAM and DIMM?

DIMM stands for Dual In-Line Memory Module, a type of computer memory that installs in the motherboard’s memory slots. … DRAM consists of a transistor and capacitor that create a memory cell, which represents a single bit. The DIMM is installed on a motherboard and stores each data bit in separate memory cells.

What is pin RAM?

It is often used as a general term used to describe SIMM, DIMM, and SO-DIMM memory. … For example, the original SIMMs had 30 pins (which are metal contacts that connect to the motherboard). However, newer SIMM chips have 72 pins. DIMMs commonly come in 168-pin configurations, but some DIMMs have as many as 240 pins.

What are DIMMs in computers?
