Computers and Technology
1 answer:
Dahasolnce [82]3 years ago
6 0

Answer:

Explanation:

A disk block works by transferring data between the disk and main memory units which are called the blocks, whose size can range drastically from 512 bytes to several thousand.  This data is converted to hardware-level cylinder, surface, and sector number  which makes accessing the data immensely slower than accessing data in the main memory. This time constraint is also the main reason as to why accessing a disk block is so expensive.

Bogdan [553]

Answer:

Yes, these things can be considered a computer. And they can also store and process data.

Explanation:

Headphones, radios, dishwashers, and remote controls are all computers because they all have some sort of logic board inside the device to control what it does. Example, a dishwasher has internal components that it uses to keep track of how long the wash/rinse cycle have lasted and how long they are supposed to last.

I hope that helps!
