Could someone explain the whole concept of giga bytes and megabytes?

Answer 1

The smallest measurment of data is a Bit, there are 8 bits in a Byte. There are 1024 bytes in a Kilobyte. There are 1024 kilobytes in a Megabyte. There are 1024 megabytes in a Gigabyte. And so on...

Answer 2

A bit is a single storage unit. It is either a 1 or a 0.
When you take 8 bits you get a byte. Is is the smallest space required to contain a character such as A-Z or 0-9. There are 256 possible combinations.
1024 bytes is a kilobyte.
1024 kilobytes is a megabyte.
1024 megabytes is a gigabyte.
1024 gigabytes is a terabyte.

Since 1024 is close to 1000 the term kilo is used. You just have to understand that in the metric system it is 1000 but in computers it is 1024 (2*2*2*2*2*2*2*2*2*2).

Answer 3

A 'bit' is one of two digits 0 or 1 as used by computers for doing what computers do.
A 'Byte' is the minimum number of bits, usually enough to represent one character. Bytes are the computers method of storing information.
A kilobyte is a storage capacity of 1024 bytes.
A megabyte in computer terminology a megabyte was
1,048, 576 bytes, but it is coming to mean 1,000,000 one million bytes in computer language.
A gigabyte originally meant 1024 megabytes, but now means 1000 megabytes (1,000,000,000 bytes, one thousand million bytes, an American Billion bytes).

The more bytes a computer has, the more it can do, and store.

I have tried to explain it, in a way I would understand.

Answer 4

They are units or data storage. To put them in perspective, all computers use only 0s and 1s and one 1 or one 0 will take up a single bit. 8 bits is a byte and this is enough storage space to store a single character like a letter or number or symbol.

1024 bytes is a Kilobyte, 1024 Kilobytes is a Megabyte, 1024 Megabytes is a Gigabyte, 1024 Gigabytes is a Terrabyte.

A floppy disk can store 1.44 Megabytes
A CD can store between 650-700 Megabytes
The text of the Bible is 4.6 Megabytes
A DVD can store either 4.7 (single layer) or 8.5 (dual layer) Gigabytes.
The entire Human Genome can fit in 3 Gigabytes

Answer 5

To answer this question you have to start with how computers store data.

To a computer data is nothing more than on or off electrical pulses, or binary pules of data. These binary pulses of data are referred to as a bit.

These bits are then organized into a group of bits referred to as a byte. Depending on the computers architecture, it may use these bytes in groups of 5 to 12 bits; however, most modern computers will represent 8 bits as a byte. [1]

From the byte we move upwards into large and larger groups of bits. Which will eventually lead to the megabyte (MB), or 1000^2 or 1024^2 bytes depending on the context. [2] Above the megabyte is the gigabyte (GB) which is 1000^3 or 1024^3 bytes depending on the context. [3]

The reason why the size of the megabyte or gigabyte is dependent up on the context is due to the fact that hard drive manufactures will typically refer to a gigabyte as 1000^3 where as programmers will typically refer to a gigabyte as 1024^2. This is due to the fact that programmers are used to working with binary numbers where as the general public is typically only used to working with decimal numbers.

Answer 6

It's just a little bit of calculations.1st u gotta know to calculate it..
It starts from Bits,Bytes,KiloBytes,MegaBytes and GigaBytes

8 bits=1Bytes
1024 Bytes =1KiloBytes
1024KiloBytes=1Megabytes
1024 Mega Bytes = 1 Giga Byte


Check this out and just play around with it to help u understand better..Hope it helps..

Answer 7

1 byte = 8 bits
1 megabyte = 1024 bytes
1 gigabyte = 1024 megabytes

Answer 8

ok - 1 bit = 1 piece of information - a single letter, number, character etc

1 byte = 8 bits

1 kilobyte = 1024 bytes (don't forget tha computers work in binary - base 2 - so all math is based on that and not base 10 or decimal)

1 mega byte = lots of KB's
and gigabyte = lots of MB's!

simple!

Answer 9

A wire can only have two states - On or Off. This at its most basic is what a bit (binary digit) is. As others correctly state the units are then multiplied. So 1 Byte is 8 bits etc...

Answer 10

gigabytes and megabytes (GB and MB) are amounts of memory space left or memory taken up. An example is let's say you make a video and put it on your computer, it might take up 200 MB or some other amount of memory.
