- 2What is RAM?Random-Access-Memory
The area where the processor stores the programs instructions. Different devices have different amounts of RAM - 3Name the scale in which data goes up inA bit = 1 or 0 = On or off
A nibble = 4 bits
A byte = 8 bits or 2 nibbles
1 Kilobyte (KB) = 1000 bytes
1 Megabyte (MB) = 1000 Kilobytes
1 Gigabyte (GB) = 1000 Megabytes
1 Terabyte ( TB) = 1000 Gigabytes - 4Name the other types of memory instead of RAMSDD ( SOLID DISC DRIVE)
HDD ( HARD DISC DRIVE) - 5Names the advantages and disadvantage of an SDDSDD
Adv - No moving parts that can be easily broken
- doesnt lose data when turned off
- produce less heat and noise
- quicker start-up time
Dis - Still uses more power than a HDD, which drains battery life
- Costs more
- Very few large capacity SDD models - 6Names the advantages and disadvantage of an HDDAdv - Large storage capacity
- Contains the opertaing system and installs apps
-Cheaper
Dis - Requires moving parts that can break
- Start up time is slower
- Produce more heat and noise - 7What is flash memory and its advantagesA type of peripheral that is ideal for portable devices eg usb
- it doesnt lose data when turned off
- it doesnt require moving parts
- it is removable so data transfer is available - 8State the three types of peripherals1. Storage Devices
