Word scramble
Unscramble the letters and write each key term on the line.
1
SICOOHNG TESGARO
Match a scenario's needs (capacity, speed, portability, durability, cost) to magnetic, optical or solid-state storage, then justify the choice with reasons.
2
LARTVUI OMERYM
Part of secondary storage (HDD or SSD) that the computer uses as extra RAM when real RAM is full. It is slower than RAM.
3
NPIGGA
Data is split into fixed-size pages. Idle pages are moved out of RAM into virtual memory, then swapped back into RAM when the CPU needs them.
4
NITRHSGHA
When RAM is full, the computer keeps swapping pages to slow secondary storage, so it becomes sluggish. Adding more RAM reduces swapping. Virtual memory is no replacement for RAM.
5
TDAA TNECRE
A building full of servers and storage devices owned by the cloud provider. It holds users' data, often copied to several locations, and is accessed over the internet.
6
DUOCL OGRTEAS
Saving data on a provider's remote servers so you can reach files from any device online, add space easily, get backups done for you and share files, without buying your own hardware.
