Lossless compression is when an image or document is reconstructed in a more efficient way using an algorithm to rewrite it. No data is lost from the file despite the compressed version taking up less mem...

Resolution is the number of pixels in a given unit area (dots per inch). A higher resolution increases the quality of an image. Colour depth is the amount of memory stored by each pixel (number of bits pe...

Firstly, represent the 3₁₆ and E₁₆ as 2 four bit binary numbers (known as nibbles). Once we have this (0011 and 1110 respectively), we can then combine them back together, into one...

Recursion is when a named block of code (a subroutine or function) calls itself. We can use recursion to describe some algorithms in very few lines. For example, the following block of p...

Https or hyper text transfer protocol secure is a method that is used to securely transfer data between the client and the webserver. This ensures that the data packets sent have been encrypted so that if...
