KEY TERMS SLIDE 2 computer system hardware software computer network central processing unit (CPU) program computer language operating system software application software

ELEMENTS OF A COMPUTER SYSTEM SLIDE 3 Input Processing Memory and storage Output device

COMPUTER NETWORKS SLIDE 4 Global computer network (Internet)  For accessing the World Wide Web  For exchanging Local computer network (intranet)  Functions like a typical website  Used to share information within an organization

Checkpoint SLIDE 5 List the four main elements of a computer system.  Input device(s)  Processing unit  Memory and storage  Output device(s)

INPUT AND PROCESSING SLIDE 6 Input: getting started Processing: making things happen  Word processing  Desktop publishing  Database software  Spreadsheet software  Presentation software

Checkpoint SLIDE 7 What are common input devices?  Common input devices include keyboard, mouse, game controller, joystick, touch-sensitive screen, scanner, voice- activated system, microphone, and camera.

MEMORY AND OUTPUT SLIDE 8 Memory and storage  Saving for later Output  Obtaining results

MEMORY CAPACITY SLIDE 9

Checkpoint SLIDE 10 How do internal and external memory differ?  Internal memory is inside the computer and holds a fixed amount of data. External memory is not stored within the computer and it is highly portable.
