Computer Hardware Basics

– any physical device or equipment used in or with a computer system (anything you can see and touch).

External hardware

  • – any hardware device that is located outside the computer.
  • – a piece of hardware device which is used to enter information to a computer for processing.
  • Examples: keyboard, mouse, trackpad (or touchpad), touchscreen, joystick, microphone, light pen, webcam, speech input, etc.
  • – a piece of hardware device that receives information from a computer.
  • Examples: monitor, printer, scanner, speaker, display screen (tablet, smartphone …), projector, head phone, etc.

Internal hardware

  • – any piece of hardware device that is located inside the computer.
  • Examples: CPU, hard disk drive, ROM, RAM, etc.

Computer Software Basics

Computer software

  • – a set of instructions or programs that tells a computer what to do or how to perform a specific task (computer software runs on hardware).
  • Main types of software – systems software and application software.

Application software

  • – a computer program that provides users with tools to accomplish a specific task.
  • Examples of application software: word processing, spreadsheets, presentation, database management, Internet browsers, email programs, media players, accounting, pronunciation, translation, desktop publishing, enterprise, etc.

System Software

– it is designed to run a computer’s hardware and application software, and make the computer system available for use. It serves as the interface between hardware, application software, and the user.

  • Main functions of system software – allocating system resources, managing storage space, storing and retrieval of files, providing security, etc.
  • Main types of systems software – operating system, device driver, utility software, programming software, etc.

– a software that controls and coordinates the computer hardware devices and runs other software and applications on a computer. It is the main part of system software and a computer will not function without it.

  • Main functions of an operating system – booting the computer, managing system resources (CPU, memory, storage devices, printer, etc.), managing files, handling input and output, executing and providing services for application software, etc.
  • Examples of operating system: Microsoft Windows, Apple iOS, Android OS, macOS, Linux, etc.

– a software program that is designed to control a particular hardware device that is attached to a computer.

  • The main purpose of device driver – it acts as a translator between the hardware device and operating systems or applications that use it.
  • It instructs computer on how to communicate with the device by translating the operating system’s instructions into a language that a device can understand in order to perform the necessary task.
  • Examples of device driver: printer driver, display driver, USB driver, sound card driver, motherboard driver, ROM driver, etc.

– a type of system software that helps set up, analyze, configure, strengthen, maintain a computer and performs a very specific task (e.g. antivirus software, backup software, memory tester, screen saver, etc.).

Is the physical equipment used for input processing and output activities in an information system?

Computer hardware is the physical equipment used for input, processing, and output activities in an information system.

What are of input output and processing in information systems?

Input captures or collects raw data from within the organization or from its external environment. Processing converts this raw input into a meaningful form. Output transfers the processed information to the people who will use it or to the activities for which it will be used.

What are the parts of system input process output?

There are four basic elements to the systems model: output, process, input, and feedback. Process represents the operations that occur to transform the inputs to the desired outputs. Inputs represent the basic materials or resources that will be transformed to the output. Feedback is the element of control.

What are the physical components in operating elements of an information system?

An information system is essentially made up of five components hardware, software, database, network and people. These five components integrate to perform input, process, output, feedback and control.
