This often leaves the hardware underutilised and an expensive infrastructure. Fig.2 Shows how the virtualisation layer is implemented in-between the host OS and the application software of the system Fig.1 Native system without virtualisation Fig.2 Virtualised system Operating system virtualisation (container) In OS virtualisation the virtualised system is implemented on top of a host operating system. Each of the virtualised containers has their own file system which operates like a normal operating system. According to shield (2007) if a file is changed on a host operating system it is usually changed in each virtual machine.

Computers would not work the same without programs. The programs on computers were made of different languages, but there are only three that serve as the foundation. The three basic types of programming languages are mechanical language, assembly languag
Another language is assembly language, which was used more than mechanical language. Assembly language is easier to compose and understand. This language was used more by programmers because it was more users friendly and made up of easily recognizable codes that translate to programming language in a one-to-one ratio. One machine language is translated for each assembly language code used. An assembler is needed to translate into machine code. The assembler was the program that translates programming language into machine code.

For example, if certain phones are selling under 5 a week by using an "IF statement" you could get these to show up as red. If certain phones are selling over 5 a week then you could make these show up as green.

It's not very time efficient, because if he lives far it takes loads of time to get to his house and then to come back.

If the sound was sampled every half second, there would be half as much information lost from the original source, but file size would be doubled. This is the trade off that has to be made between file size and quality. Bit depth is the number of bits of information recorded per second .The higher the bit depth means, the higher the sample rate and this results in higher quality sound file. A good example of bit depth is in CD quality audio which has a bit depth of 16 bits and a sample rate of 44.1 kHz.
