Document Summary

Easier to ship or transport if the system needs repair. More difficult to steal, less susceptible to damage from dropping. Storage subsystem (hard drive and other drives) First, it fetches the required piece of data from ram, and then decodes the instruction into something the computer can understand. Once the cpu has decoded the instruction, it executes the instruction and stores the result to ram before fetching the next instruction. This process is called machine cycle: core is a complete processing section from a cpu embedded into one physical chip, hyperthreading provides quicker processing of information by enabling a new set of instructions. It gets data to the cpu for processing much faster than bringing the data in from. Level 2 cache contains more storage area than level 1 cache: front side bus (fsb) connects the cpu to the system memory (ram). The systems overall performance depends on many other factors, including the ram installed and hard drive speed.
