"To speed up magnetic hard drive performance , ___________ is often used. "

Harrizon [31]3 years ago
3 0

Answer:

disk caching

Explanation:

Hi,

Magnetic hard drives use disk caching to speed up performance. This method is quite ingenious because what it does is that in a section of memory in your pc, it keeps a copy of information that was previously accessed in the hard disk. So, next time if the same data is requested, the system can refer to cache to get quick access rather than going to the hard disk (which is slower).

Can someone please explain binary addition to me? i have a test tomorrow yikes
umka2103 [35]

Answer:

its easy

Explanation:

there are are 5 main rules

in binary there are 2 number 0 and 1

0 + 0 = 0

0 + 1 = 1

1+0=1

1+1=0 carry 1

e . g

1 1 1

1 0 1 0 1 0

+ 1 1 0 0 1 0

-------------------------

1 1 1 1 1 0 0

*in bold are the ones that you need to carry.

in decimal there are 10 possible numbers 0- 9

when you do 1 + 9 it becomes 10, this can be done easily, however if you do 1 + 9 in a table like above, you will get 0 for the first column and you will carry 1 to the next column .

in binary is the same idea but using on 2 numbers 1 and 0

e.g

1

1

+ 9

----------

1 0

*in bold are the ones that you need to carry.

hope it helps and good luck in your exam.
