Components of a computer system

Components of a Computer System

  • Hardware

  • Software


Hardware

Hardware

  • Physical components of a computer system

  • Examples: Monitor, Keyboard, Mouse, Hard drive, Motherboard, DVD drive, CD Rom, Flash drive, Memory, Video Card


Software

Software

  • Application Program

    • Tools that help you accomplish your work:

      (designing, drafting, rendering, word processing, Ex: AutoCAD LT 2005, Microsoft Word)

  • System Software (Operating System)

    • Platform to run application programs:

      (Windows XP,Vista, MAC OS X)


What is cad

What is CAD?

  • An electronic tool that enables you to make quick and accurate drawings with the use of the computer.

  • CAD is an acronym for:-Computer Aided Drafting-Computer Aided Design-Computer Aided Drafting and Design (CADD)


Capabilities of a cad system

Capabilities of a CAD system

  • Flexibility of editing- ability to make quick alterations to a drawing

  • Units and Accuracy levels- ability to change and work with different units and create highly accurate drawings

  • Storage and Access for drawings- save space, quick access, more organized


Capabilities continued

Capabilities (continued)

  • Sharing CADD drawings- electronic files can be transferred easily and quickly from any location

  • Design- Allows you to quickly change current designs with accuracy


Main functions of all cad systems

Main functions of all CAD systems

  • Draw-

    • add geometry to drawing (lines, arcs, circles, ellipses, text)

  • Edit-

    • change elements of drawings (erase, move, array, copy, offset)

  • Data Output-

    • view/display functions, printing (zoom, pan, scale, colors)


Functions continued

Functions (continued)

  • System Control-

    • Setting drawing environment (layers, line types, styles, drawing space, drawing aids)

  • Data Storage and Management-

    • Filing, Saving drawings (open, saving, copying, deleting files)
