motherboard A n module is a removable flash memory device about one half the size of a PC Card that adds memory communications and multimedia capabilities to computers Express card size is the number of bits the processor can interpret and execute at a given time Word Bluetooth technology is an alternative to IrDA that uses radio waves to transmit data between two devices Preventive maintenance of your computer requires a few basic products including All of the above A USB is a device that plugs in a USB port on the system unit and contains multiple USB ports in which users plug cables from USB devices Hub ROM chips called contain permanently written data instructions or information that is recorded when the chip is manufactured Firmware A processor contains small high speed storage locations called that temporarily hold data and instructions Registers A n processor is a chip with two or more separate processor cores Multi core One gigahertz GHz equals one ticks of the system clock per second Billion The wider the bus the the transfer of data fewer the number of transfer steps required and the faster 5 Chapter 5 CGS Chapters 1 6 A n scanner works in a manner similar to a copy machine except it creates a file of the document in memory instead of a paper copy Flatbed A retinal works similarly to an iris recognition system but instead scans patterns of blood vessels in
