1.6 Put the words into the gaps. Processors and memory

Chips dual core megabytes megahertz

motherboard processor speed upgraded

The ‘brain’ of a computer is the processor. Most of these are made by Intel and AMD, and are sometimes referred to as ‘Chips’. The fastest processors are dual core which means that these are two processors working together. The speed of a processor is measured in megahertz which is usually written as MHz.

A computer’s memory is measured in megabytes. If a computer has 1,024 megabytes of memory, and the memory type is SDRAM, this is written as 1,024 MB SDRAM, and is pronounced ‘a thousand and twenty-four megabytes ess-dee-dram’. The processor and memory modules are located on the motherboard. Changing a computer’s processor is not generally practical, but the memory can usually be upgraded.
