SIMMs
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)
add (v)

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/

A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of 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.
