slots

These are memory chips The more you have, the more work you can do

at a time Empty memory slots mean you can add more memory.

Single In-line Memory Module

- chip (n) = integrated chip = IC

/ˈɪntɪɡreɪtɪd/

- empty (adj) /ˈempti/

- slot (n)

Cache memory

It’s part of the memory store It has extremely fast access It’s faster than normal RAM It can speed up the computer.

- extremely (adv) /ɪkˈstriːmli/

- access (n), (v) /ˈækses/

- speed up (v)

- RAM (Random Access Memory)



Expansion slots

These let you add features such as sound or a modem to a

computer.

- add (v)

- feature (n) /ˈfiːtʃər/



ROM (Read Only Memory

This kind of memory contains all the instructions your computer needs to activate itself when you switch on Unlike RAM, its contents are retained when you switch off (constant information)

- contain (v) /kənˈteɪn/  container (n)

- activate (v) /ˈæktɪveɪt/

- switch on >< switch off (v)

- content (n) /ˈkɒntent /

- retain (v) /rɪˈteɪn/

Add the processor

Fit the new

motherboard

Remove the old motherboard Put it back together

Add the memory Don’t touch the contacts.

A memory cache, sometimes called a cache store

high-speed static RAM (SRAM) instead of the

slower and cheaper dynamic RAM (DRAM) used for main memory Memory caching is effective because most programs access the same data or instructions over and over By keeping as much

of this information as possible in SRAM, the

computer avoids accessing the slower DRAM
