Computer System
COMPONENTS of COMPUTER SYSTEM
A complete, working computer. Computer systems will include the computer along with any software and peripheral devices that are necessary to make the computer function. Every computer system, for example, requires an operating system. A system of interconnected computers that share a central storage system and various peripheral devices such as a printers, scanners, or routers. Each computer connected to the system can operate independently, but has the ability to communicate with other external devices and computer. It includes the computer along with any software and peripheral devices that are necessary to make the computer function.
PEOPLEWARE
Managers
System Analyst/Designer
Programmers
Operators/Technicians
Users
Peopleware is a term used to refer to one of the three core aspects of computer technology, the other two being hardware and software. Peopleware can refer to anything that has to do with the role of people in the development or use of computer software and hardware systems, including such issues as developer productivity, teamwork, group dynamics, the psychology of programming, project management, organizational factors, human interface design, and human-machine-interaction
SOFTWARE
System Software
Application Software
Software is any set of machine-readable instructions that directs a computer's processor to perform specific operations. Computer software contrasts with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other. Using a musical analogy, hardware is like a musical instrument and software is like the notes played on that instrument.
HARDWARE
Computer hardware is the collection of physical elements that constitutes a computersystem. Computer hardware refers to the physical parts or components of a computer such as the monitor, mouse, keyboard, computer data storage, hard disk drive (HDD), system unit (graphic cards, sound cards, memory, motherboard and chips), etc. all of which are physical objects that can be touched (known as tangible). In contrast, software is instructions that can be stored and run by hardware.
SYSTEM UNIT
INPUT DEVICES
Input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to aninformation processing system such as a computer or other information appliance. Examples of input devices include keyboards, mice,scanners, digital cameras and joysticks.
OUTPUT DEVICES
STORAGE DEVICES
Output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form.
Storage device is a device for recording (storing) information (data). Recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.
