These are memory chips The more you have, the more work you can 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) /ˈempt/ - slot (n)
(9)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)
(10)Expansion slots
These let you add features such as sound or a modem to a
computer. - add (v)
- feature (n) /ˈfiːtʃər/

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)

(13)A memory cache, sometmes called a cache store
or RAM cache, is a porton of memory made of high-speed statc RAM (SRAM) instead of the
slower and cheaper dynamic RAM (DRAM) used for main memory Memory caching is effectve because most programs access the same data or instructons over and over By keeping as much of this informaton as possible in SRAM, the
