Understanding bits, bytes, and other units used in computer system.
A bit has only one of two values that is 0 or 1, where electrical values of 0 stand for off and 1 stand for on. It is a smallest unit of data on a system.It is binary digit.
A byte is collection of 8 bits . A byte store a single ASCII character.
An alphanumeric character lets says “A” is stored as 1 byte.
Example : To store the letter ‘R’ then it will store as ‘01010010’ which is 8 bits and 1 byte.
A kilobyte (KB) is equal to 1,024 bytes.
Computer memory and storage used megabytes (MB) and gigabytes (GB).
1MB = 1,024 kilobytes, or 1,048,576 (1024×1024) bytes.
1GB = 1,024 MB, or 1,073,741,824 (1024x1024x1024) bytes.
1 Terabyte (TB) = 1,024 GB.
1 Petabyte (PB) = 1,024 TB.
1 Exabyte (EB) = 1,024 PB.
1 Zettabyte (ZB) = 1,024 EB.
1 Yottabyte (YB) = 1,024 ZB.
Also there are Hellabyte or Brontobyte.
some unit which is used in computer system
1 kilobyte (KB) is equal to 1,024 bytes
1 megabyte (MB) is equal to 1,048,576 bytes
1 gigabyte (GB) is equal to 1,073,741,824 bytes
1 terabyte (TB) is equal to 1,099,511,627,776 bytes
1 petabyte (PB) is equal to 1,125,899,906,842,624 bytes
Understanding difference between Mbps and MBps?
Now understanding uppercase B (B) and lowercase b (b).
Uppercase B is stands for bytes and lowercase b stands for bits.
1MBps = 8Mbps
Example : 100 KB (kilobytes) = 800 Kb (kilobits).
Data SPEEDS are usually described in terms of BITS:
1,024 bits = 1 Kilobit
1,024Kb = 1 Megabit
1,024Mb = 1 Gigabit
1,024Gb = 1 Terabit
Mbps means megabits per second, here Mb means upload and download speeds.
MBps = Mega Bytes per second
Mbps = Mega bits per second
Example 100Mbps is only 12.5MBPS
Impotant Point to Remember :
Generally, Internet service providers show in Mbps.
Example : Speed upto 16 Mbps
While you download from internet, it is in MB/s or KB/s (Bytes).
In short, 16 Mbps plan, your maximum download speed will be 2 MB/s.
