Compression of IPv6 address
IPv6 address is short form of IP address version 6. It is basically a 128 bit address. In IPv6 address, hexadecimal notation is preferred. There are total 8 fields in IPv6 hexadecimal notation and each field consists of 16 bits. Hence, total bits are 8 x 16 = 128 Rules for compression: There are basically three rules for compression: Rule-1: When o

Difference between Inter and Intra Frame Compression
In Compression, we reduce the size of our data to achieve high efficiency and easy storage. It is quite cumbersome to transfer files having large size so we need to compress it. Compressed file takes less time for data transmission and reduce the cost of storage. Compression Ratio = B1 / B2 where, B1 = Total Numbers of bits required to represent da

LZW (Lempel–Ziv–Welch) Compression technique
Why do we need a Compression Algorithm? There are two categories of compression techniques, lossy and lossless. Whilst each uses different techniques to compress files, both have the same aim: To look for duplicate data in the graphic (GIF for LZW) and use a much more compact data representation. Lossless compression reduces bits by identifying and

Maximum Data Rate (channel capacity) for Noiseless and Noisy channels
As early as 1924, an AT&T engineer, Henry Nyquist, realized that even a perfect channel has a finite transmission capacity. He derived an equation expressing the maximum data rate for a finite-bandwidth noiseless channel. In 1948, Claude Shannon carried Nyquist's work further and extended to it the case of a channel subject to random(that is, t
