1. Give reasons for the choice of components to meet a given need – M2 By Ridjauhn Ryan

2. Introduction In this presentation I will be informing you about why I chose this specific type of RAM, CPU and OS.

3. RAM Also known as ‘Random accessed memory’ G.Skill 8GBXL Main Memory DDR3 8 GB PC1600 CL9 Ram Kit 2x 4 GB £33.55 Having more RAM means you need to read from the excruciatingly slow hard drive less often, and faster RAM means your CPU can grab its bits faster. There’s really no such thing as too much RAM, but there is such a thing as spending too much on RAM. What you do with your computer is what dictates whether or not more memory is actually practical Also known as ‘Random accessed memory’

4. CPU There’s really nothing random about it; the CPU (generally) knows exactly what data it is dealing with. When the CPU is processing data, it’s grabbing small bits in your systems memory, constantly jumping from place to place, reading, writing, and rewriting information. If your CPU had to process data directly on the hard drive, there would be a massive bottleneck.

5. OS An OS is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. The operating system acts as an intermediary between programs and the computer hardware. Examples of popular modern operating systems include Android, BSD, iOS, Linux, Mac OS X, Microsoft Windows Also known as ‘operating system’
