BITS AND
BYTES :-
Bits
are most often used to measure data transfer speeds. This may refer to how fast
you are downloading a file, or how fast your Internet connection is. For
example, if you are downloading a file on cable modem, your download speed might
be 240Kbps. This is much faster than a dial-up modem, which maxes out at
56Kbps.
Bytes,
on the other hand, are used to measure data storage. For example, a CD holds
700MB (megabytes) of data and a hard drive may hold 250GB (gigabytes). The
other important difference is that bytes contain eight bits of data. Therefore,
a 240Kbps download is only transferring 30KB of data per second. However,
kilobytes per second is not as commonly used as kilobits per second for
measuring data transfer speeds. After all, using kilobits per second (Kbps)
makes your connection sound eight times faster.
It
is important to know that bytes are abbreviated with a capital B, where as bits
use a lowercase b. Therefore, Mbps is megabits per second, and MBps is
megabytes per second. So 8Mbps is equal to 1MBps.
KILOBITS AND
KILOBYTES :-
In
data communications, a Kilobit is one thousand bits. It is used to measure the
amount of data transferred per second. Kilobits per second is shortened to
kb/s, Kbps or kbps (as opposed to KBps, which is Kilobytes per second. ... The
lowercase b is commonly used to denote bits, while the uppercase B is used for
bytes.
MEASURE OF
FILE SIZE :- KBps
File
size i.e. how big the file or how much space a file occupies in the hard disk
measured in terms of Kilo Bytes (KB upper case “K” and upper case “B”). In
computing terms the upper case “K” stands for 1024. 1024 is computed from 210.
(2 power 10). 2 denote the number of characters in the binary system which is
used to store data in the disc (ones and zeroes).
Other
abbreviations like mega, giga and terra also use the base as 1024,
1KB
(Kilo Byte) = 1024 Bytes (approximately 1000 Bytes)
1MB
(Mega Byte) = 1024 KB (approximately 1000 Kilo Bytes or 1 million Bytes)
1GB
(Gigabyte) = 1024 MB (approximately 1000 Mega Bytes or 1 billion Bytes)
1TB
(Terra Byte) = 1024 GB (approximately 1000 Gigabytes or 1 trillion Bytes)
MEASURE OF
DATA TRANSFER SPEED :- kbps
Data
transfer speed over the networks (including the internet) is calculated in
terms of bits per second: kilobits (kb small case “k” and small case “b”). The
higher the kbps i.e. more the bits transferred per second, more the speed,
faster the network/connection. Here k stands for 1000.
1
kbps (kilo bits per second) = 1000 bits per second
1
Mbps (mega bits per second) = 1000 kilo bits per second.
1
Gbps (giga bits per second) = 1,000 mega bits per second.
DOWNLOAD
SPEED (APPROX)(MARKED IN ITALICS) :-
Internet
connectivity Download speed (approx)
256
kbps 31.3 KBps
384
kbps 46.9 KBps
512
kbps 62.5 KBps
768
kbps 93.8 KBps
1
mbps ~ 1000kbps 122.1 KBps
I
have mentioned download speed as approximate because they will vary (always
reduce) by 15 – 20% due to network signal loss, computer hardware overheads
etc. So for realistic, real world figures always reduce 15 – 20% from the
computed KBPS download speeds.
Now
I guess the confusion of kbps and KBps has cleared away. Just remember when you
talk in terms of network it’s always bites per second (bps) and when you talk
in terms of storage and files its always Bytes per second (Bps).
