Study Notes

Grading Policy

  • Midterm exam is worth 30 marks
  • Final exam is worth 40 marks
  • Sessional work is worth 30 marks
    • Includes quizzes, lab tasks, presentations, and class participation

Data vs. Information

  • Data is unorganized facts
    • Can be text, images, audio, or video
  • Information is processed data in a meaningful format
  • Information processing converts data into information.

Hardware

  • Hardware is the physical components of a computer.
  • Internal hardware is located inside the system unit.
  • External hardware is located outside the system unit and connects via wired or wireless connections.
  • All five computer operations utilize hardware devices.

Input Devices

  • Input devices are used to enter data into the computer.
  • Examples: keyboards, mice, scanners, cameras, microphones, touch pads, touch screens, fingerprint readers

Processing Devices

  • Processing devices perform calculations and control the computer's operation.
  • The central processing unit (CPU) and memory are examples of processing devices.
  • Output devices present results to the user.
  • Examples: Monitors, printers, speakers, projectors

Storage Devices

  • Storage devices are used to store data on or access data from storage media.
  • Examples: hard drives, CD/DVD discs and drives, USB flash drives

Communications Devices

  • Communications devices allow users to communicate with others and access remote information electronically.
  • Examples: Modems, network adapters (NIC), routers

Software

  • Software is the set of programs or instructions used to tell hardware what to do.
  • System software starts up the computer and controls its operation.
  • Without the operating system, the computer cannot function.
  • Most operating systems use a graphical user interface (GUI) to interact with the user via icons, buttons, tiles, etc.
  • Examples of operating systems: Windows, Mac OS, Linux, Android

Application Software

  • Application software performs specific tasks or applications.
  • Examples:
    • Word processing programs
    • Multimedia programs
    • Web browsers
    • E-mail programs

Computer

  • A programmable, electronic device that accepts data, performs operations on that data, and stores data.
  • Computers follow instructions called programs.
  • There are five basic operations a computer performs:
    • Input: entering data into the computer
    • Processing: performing operations on the data
    • Output: presenting the results
    • Storage: saving data, programs, or output for future use
    • Communications: Sending or receiving data

Computer Users and Professionals

  • Computer Users (end users) use a computer to obtain information.
  • Computer Professionals include
    • Programmers: write programs that computers use
    • Systems analysts: design computer systems
    • Computer operations personnel: manage day-to-day computer operations
    • Security specialists: secure computers and networks against hackers

Computers To Fit Every Need

  • The six basic categories of computers are:
    • Embedded computers
    • Mobile devices
    • Personal computers
    • Servers
    • Mainframe computers
    • Supercomputers

Embedded Computers

  • Embedded computers are integrated into a product and designed to perform specific tasks or functions for that product.
  • They cannot be used as general-purpose computers.
  • Examples of devices with embedded computers:
    • Household appliances
    • Thermostats
