CPU• Ghz is the speed of the CPU. How fast it thinks. Anything over 3Ghz is very quick. Between 2-3 is good.• We need a multi-core processor (dual or quad). The reason is the more cores the easier it is to multitask. ie Open PhotoShop, Internet Explorer, Flash at the same time.• The Intel i3, i5 and i7 are the newest incarnation of CPU’s. They are multicore processors but can hyperthread to form twice the amount of cores. They create virtual cores within the physical cores.
RAM• The bigger the better.• Generally 2GB RAM is minimum for a office computer running Office Suite.• Anything above 6-8GB is desired for a web designer.• The reason is the more RAM you have the better your computer will deal with having larger files and programs.• Ie video files, Adobe software.
Graphics Card The graphics card takes pressure off the CPU to convert data into colour pixels on your screen Every motherboard comes with an on-board GPU but it has limited functionality.• Stand Alone Graphics card are add-ons to the motherboard and vary in memory size.• The higher the onboard memory the better. 256MB of memory is minimum and 1GB is preferred.
HDD• HDD refers to hard drive.• The bigger the better but you must explain why.• So 1TB or above is good. Your explanation might include the need for large file storage for video files, animation files and large amounts of graphics.
Monitor• Size is important.• LCD is standard now. Size would be 24 inches or above.• High Definition for editing and watching video and graphics.
Peripheral Devices• Any device which requires a USB connection (avoid mouse and keyboard).• Graphics tablet• Scanner• Multimedia projector• Colour laser jet printer
