Document Summary
Cache memory: form of ram that gets data to the cpu for processing more quickly than it can from regular ram. Clock speed: dictates how many instructions the cpu can process each second. Control keys: used with other keys to perform shortcuts. Control unit: coordinates the activities of computer components. Disk defragmenter: reorganizes files making the hard drive work more efficiently. Embedded computer: specially designed computer that can perform complex calculations extremely rapidly. Expresscard: allows reading of flash memory cards such as memory sticks; interface to connect peripheral devices to a computer, usually a laptop computer. Function keys: shortcut keys to perform special tasks in software. Hyper-threading: simultaneous execution of more than one instruction. Major functions of a computer: input, process, output, storage. Memory modules: small circuit boards that hold a series of ram chips and fit into special slots on motherboard. Overclocking: running cpu at a faster speed than manufacturer recommends.
