Examples of Computer


New model of computer VIOS

Old Model of computer

Flat Screen Computer

  • Any collection of facts
forms of data
Forms of DATA
  • Numeric Data = (0 – 9)
  • Alphanumeric Data = (text data)
  • Graphic Elements
  • Physical Data = ex. Temperature, sound voice, light
data processing
Data Processing
  • Is the manipulation of data into a more & useful form.
  • Modern name for paperwork.
  • The outcome of the process, also known as the processed data.
mechanical data processing
Mechanical Data Processing
  • Data that processes manually.

Ex. Typewriters sorters, calculators, collators, tabulators, duplicators, and verifiers

electronic data processing
Electronic DATA Processing
  • Data that process electronically which is used in storage.

Ex. Computer

data processing cycle
Data Processing Cycle


Process / Manipulate


data processing life cycle
Data Processing Life Cycle
  • Input
    • Initial data or input data are prepared in some convenient form for processing
  • Processing
    • Input data are change, and usually combined with other information to produce data in more and useful form
  • Output
    • The results of the preceding processing steps are collected
  • Is a collection of elements or parts that work together as a point in order to solve specific problems.



People Ware

  • In its simplest form, a computer consist of five functionally independent main parts: Input, Memory, Arithmetic and Logic Unit (ALU), Control Unit (CU), & the Output Unit. As indicated in the figure 1.1.






5 functionally independent main parts of hardware
5 Functionally Independent main parts of HARDWARE
  • Input
  • Memory
  • Arithmetic & Logic Unit (ALU)
  • Control Unit (CU)
  • Output Unit
input units
Input Units
  • Accept coded information by means of input units or devices
central processing unit cpu
Central Processing Unit (CPU)
  • Brain of the computer that process data enter into the computer.
  • It is the parts of the computer that translate commands & run programs.
  • Is the center of the modern computer it is integrated circuit or microchip that contains the entire CPU of a Computer.
output unit
Output Unit
  • Enables the computer to present information to the user.
primary memory
Primary Memory
  • You can store a program over a short period of time. If you turn off the computer, all the data’s stored will be LOST.
secondary memory
Secondary Memory
  • You can store a program over a long period of time.

Ex. cd, Flash Disk having 1Giga bytes

  • It refers to the task of creating software.
programming language software
Programming Language Software
  • Used to create system and application program.
  • An artificial language used to define step-by-step instructions that can be processed and executed by the computer.
system software
System Software
  • Refers to the operating system and utility programs that manage computer resources.
  • Controls the standard activities or operations inside the computer and directs the computer how to operate its hardware resources.
application software
Application Software
  • Are the programs used to solve specific processing problems.
  • Are used in order to be productive & efficient in doing in the work in school, in the office, and in any business or personal transactions.
people ware1
People Ware
  • Responsible in developing the computer system.
  • Develops the system.
technical user
Technical User
  • One who design at the same time implement or carrying out the system.
5 classes belong to technical users
5 Classes belong to Technical Users
  • System Analyst– analyses the problem of the program
  • Computer Programmer – makes the programs that man needs
  • System Engineer – developed the system
  • Application Developer – upgrades the system

– add programs execute

  • Computer Technician – who repairs the computer
end users
End Users
  • Primary operations of the computer
  • Are the one who enters the date into the computers.

Ex. Data encoder, computer operators, computer hobbyist, application user

dos disk operating system1
DOS(Disk Operating System)
  • An operating system with a collection of software programs that supervises the activities that takes place with in the computer, it also manage coordinates & in a sense brings life to the computer hardware.
  • Every computer must have operating system to control its basic input & output operations-DOS is said to be a command line interface (CU) software.
working with dos
“Working with DOS”
  • From its introduction in 1981 to the reface of DOS 6.2 . In 1993, DOS has established itself as the primary operation system for microcomputer.
the command live
“The Command Live”
  • Most computer user, associate DOS with the command or DOS system prompt. Although some device users breakout is a cold sweat at the sight of a c/> prompt on the computer screen, this are many people who prefer the easy of typing command directly.
  • Is an operating system that provides you a wide variety of information in a wide range of formats.
windows graphical user interface
Windows Graphical User Interface
  • Provides easy access to large volumes of sounds, graphics, multimedia information, & provides of platform for the development of even more sophisticated applications.
what s new in windows
What’s New in Windows?
