drive DVD 4 Central processing unit CPU hardware that interprets and executes system and application software instruction and coordinates the operation of all hardware a Random Access Memory RAM temporary holding area for information you re working with as well as the system and application software instructions that he CPU currently needs 5 Telecommunications device tool used to send information to and receive it from another person or computer in a network a Example Modem 6 Connecting devices such things as a USB port into which you connect a printer connector cables to connect printer to USB port and internal connecting devices on a motherboard 1 Application software software enabling you to solve specific problems and 2 Types of Software perform specific tasks a Microsoft Word 2 System software handles tasks specific to technology management and coordinates the interaction of all technology devices includes network operating system
