Part 1 Block 3 - Putting it all together Flashcards
The microchips that contain the heart of the computer, the processor and main memory, are mounted on a circuit board called a m_____________________.
motherboard
Name 3 peripheral devices?
A printer, a mouse, a disk drive…
Secondary memory (or secondary storage) is the term given to the storage devices that contain p______________ data.
persistent
In most devices, secondary storage is built into the case and is usually supplied in the form of a h_____ d_________ drive or a s_____-s_________ drive
a hard disk drive
solid-state drive
Which device, a hard-disk drive or a solid-state drive, uses a rotating electromagnetically charged surface to store data?
a hard disk drive
Which device, a hard-disk drive or a solid-state drive, uses integrated circuits to store data?
a solid-state drive
Which device, a hard-disk drive or a solid-state drive, has the advantage of containing no moving parts and being much faster to access.
the solid-state drive
Secondary memory is used to store program code and data files that are not immediately needed by the computer system, so it is sometimes referred to as f______-s________ memory.
file-storage memory
For secondary storage (as well as file sizes and data transfer rates) should be use binary or decimal prefixes?
decimal prefixes
The memory hierarchy
Why do we not just build computers with a giant main memory?
it is expensive
The memory hierarchy
The fastest memory access is in the r___________.
registers
The memory hierarchy
Registers are built directly into the processor, so there are usually a fixed number of them – typically fewer than 50.
Can we add more?
No
The memory hierarchy
The slowest memory access is to h_____ d_______ storage, roughly 10,000 times slower than for the registers.
hard-disk
The memory hierarchy
Which is cheaper, hard disk storage memory or register memory?
the slowest one, so, hard disk storage memory.
The memory hierarchy
Although secondary storage is a hardware component, the memory resources of a computer system are managed by s________ – specifically the operating system.
software
