Question

Ok so how would I work this out?
Please do not give me the answer just explain to me how I can solve it thnxs

Write each answer as a power of 2. Show your work and explain your steps.
a. Computer capacity is often measured in bits and bytes. A bit is the smallest unit, which is a 1 or 0, in the computer's memory. A byte is 2^3 bits. A megabyte (MB) is 2^20 bytes. How many bits are in a megabyte?

Answer 1

well if i said a bit is 8 and a megabit is 24 how many bits to a megabyte ?
23/8
therefore 3 bits. Try the same logic here

Answer 2

24/8 my bad

Answer 3

8 of what and 24 of what?

Answer 4

just anything really, i chose arbitrary numbers to show a concept. But i did explain it badly
Basically you have to look at the question as asking. How many Bits go into A byte which you are told is 2^3
Then you know there are 2^20 bytes to a megabyte so to find the amount of bits, convert the 2^20 bytes to (this is what your looking for) amount of bits

Answer 5

1byte = 2^3 bits
1 megabyte = 2^20 bytes!
So
1 megabyte = 2^20 bytes OR 2^20 * 2^3 BITS
= 2^23 bits
Got it? :)

Answer 6

@Taplin44 : Has done it in a better way though.

Answer 7

No :'(

Answer 8

1 kilometer is 1000 metres!
1 metre is 100centimeters
How many centimeters is 1 kilometers?

Answer 9

One thing I don't under stand is it says o write it in a power of 2 and also it say a bit is 0 or 1

Answer 10

This is a bit = 0 or 1
This maybe a byte: 01000101

Answer 11

This is confusing me...

Answer 12

10,000 centimeters

Answer 13

1 miunte is 60 seconds
1 second is 100 miliseconds
How many miliseconds is 1 minute!

Answer 14

dont get bogged on the complications of the question, just identify what it is asking.
When it says as a power of two it means do the calculation AkashdeepDeb showed
1 megabyte = 2^20 bytes OR (2^20) * (2^3) BITS
=2^23 (see how it is 2^something)
what a byte actually is is meaningless here

Answer 15

It actually is 100,000 centimeters
100 * 1000
Getting it?

Answer 16

Ok but how do I do the problem I still don't under stand

Answer 17

1 miunte is 60 seconds
1 second is 100 miliseconds
How many miliseconds is 1 minute!

Answer 18

6000?

Answer 19

Excellent!!
Now that IS what the question asks you!
How many bits are in a megabyte?
1 byte = 2^3 bits
1 megabyte = 2^20 bytes
1megabyte = ? bits
= 2^20 * 2^3

Answer 20

That IS how you solved the other questions right?
Solve this in the same way!! :D

Answer 21

Ok so 1 megabyte = 2^23 Bits?

Answer 22

YES!! :D

Answer 23

Understood? :)

Answer 24

Yes but do I need to work out the exponent for this question

Answer 25

Exponent = 23!
How?
Like this....
2^20 * 2^3 = 2^(20+3) = 2^23 bits
Got it? :)

Answer 26

Yes I got that but I mean like do I need to work it out like do 2*2*2*2*2 & so on for this?

Answer 27

No No Noo!!!
No need!! :D
Hahah.

Answer 28

Ok good lol thanks

Answer 29

:)

Answer 30

Here is the other part to the question I need some help on it to if you could please help
A gigabyte (GB) is 2^30 bytes. How many Megabytes are in a gigabyte? How many bits are in a gigabyte?
Ok so would it be 1 Mega bytes with 2^7 left over?

Answer 31

@AkashdeepDeb

Answer 32

1 gb = 2^30 bytes
1 mb = 2^20 bytes
1gb = 2^30/2^20 = 2^10 mb
And for 1 gb to bits
1 gb = 2^30 * 2^3 bits [Because 1 bytes is 2^3 bits]
= 2^33 bits.

Answer 33

I am a little bit busy now.
Whenever I am jobless I'll show you a cool method called the unit factor method.
THat'll help you a lot in conversions.

Answer 34

Ok thanks
