Memory & Storage
Cards in this deck (8)
- 1RAM (Short for Random Access Memory) allows the computer to do what?To store temporary files and or cache so that different programs can quickly load resources, rather than have to wait longer when grabbing them from a hard drive.
- 2What is the difference between RAM and ROM?RAM is volatile, ROM is not.
- 3In what way (the main way) does an SSD out-perform a generic hard disk drive?An SSD has zero moving parts, which allows it to access and retrieve its data quickly, whereas a HDD must read the data from the disks, which takes time.
- 4What does a memory cache do?Cache is stored temporarily so that the CPU can refer and or retrieve the data without needing to contact the RAM, asking it to access it every time - which cuts down on loading times.
- 5What is bus width?Bus width is how many bits of information RAM can send to the CPU at the same time.
- 6What is latency?The number of clock cycles needed before the particular bit of information can be read.
- 7Which kind of computer memory is first activated on boot?BIOS
- 8In what way does virtual memory free up RAM?The system looks at the files on RAM which haven't been accessed in some time, it then copies them to the hard drive, and then frees up the RAM for other processes.
