Write about major hardware components of a computer system

Motivation[ edit ] Due to the exploding complexity of digital electronic circuits since the s see Moore's lawcircuit designers needed digital logic descriptions to be performed at a high level without being tied to a specific electronic technology, such as CMOS or BJT. HDLs were created to implement register-transfer level abstraction, a model of the data flow and timing of a circuit. There are different types of description in them "dataflow, behavioral and structural". Example of dataflow of HDL:

The Ishango bone Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers.

The earliest counting device was probably a form of tally stick. Later record keeping aids throughout the Fertile Crescent included calculi clay spheres, cones, etc. The Roman abacus was developed from devices used in Babylonia as early as BC.

The major hardware components of a computer system are: Processor; Main memory; Secondary memory; Input devices; Output devices; For typical desktop computers, the processor, main memory, secondary memory, power supply, and supporting hardware are housed in a metal case. Many of the components are connected to the main circuit board of the computer, called the motherboard. § Implementation of Texas Essential Knowledge and Skills for Transportation, Distribution, and Logistics, Adopted (a) The provisions of this subchapter shall be implemented by school districts beginning with the school year. John Catsoulis lives under the tropical sun in Brisbane, Australia. He has a Bachelor of Science with Honors (Griffith University) with a triple major in quantum physics, electronics and mathematics, and a Master of Engineering (La Trobe University) in specialized computer architectures.

Since then, many other forms of reckoning boards or tables have been invented. In a medieval European counting housea checkered cloth would be placed on a table, and markers moved around on it according to certain rules, as an aid to calculating sums of money.

The ancient Greek -designed Antikythera mechanismdating between and BC, is the world's oldest analog computer. The Antikythera mechanism is believed to be the earliest mechanical analog "computer", according to Derek J.

It was discovered in in the Antikythera wreck off the Greek island of Antikytherabetween Kythera and Creteand has been dated to c. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later.

Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. A combination of the planisphere and dioptrathe astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy.

An astrolabe incorporating a mechanical calendar computer [9] [10] and gear -wheels was invented by Abi Bakr of IsfahanPersia in The sectora calculating instrument used for solving problems in proportion, trigonometry, multiplication and division, and for various functions, such as squares and cube roots, was developed in the late 16th century and found application in gunnery, surveying and navigation.

The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. A slide rule The slide rule was invented around —, shortly after the publication of the concept of the logarithm. It is a hand-operated analog computer for doing multiplication and division.


As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions.

Slide rules with special scales are still used for quick performance of routine calculations, such as the E6B circular slide rule used for time and distance calculations on light aircraft. In the s, Pierre Jaquet-Droza Swiss watchmakerbuilt a mechanical doll automaton that could write holding a quill pen.

By switching the number and order of its internal wheels different letters, and hence different messages, could be produced. In effect, it could be mechanically "programmed" to read instructions.

It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location. The differential analysera mechanical analog computer designed to solve differential equations by integrationused wheel-and-disc mechanisms to perform the integration.The four main components of a computer system are input devices, output devices, processing devices and the storage devices used to store data within the computer system.

These are the hardware components of a computer system; software is a set of digital instructions for the computer stored in the memory.

Programming Languages. As I noted earlier, software developers create software using one of several programming languages. A programming language is an artificial language that provides a way for a programmer to create structured code to communicate logic in a format that can be executed by the computer hardware.

Devices that enable a computer to connect to other components; includes modems and network interface cards. Control Unit The component in any computing system that works in coordinatin with the central processing unit to instruct, maintain and control the flow of information. The four main components of a computer system are input devices, output devices, processing devices and the storage devices used to store data within the computer system.

These are the hardware components of a computer system; software is a set of digital instructions for the computer stored in the memory.

OUTPUT/DISPLAY DEVICES Output devices are hardware components which are used to display or print the processed information. Output devices include monitor (display screen), printer, plotter, speaker, computer output microfilm etc.

Monitor Monitor is commonly known as Visual Display Unit (VDU) and it is the main output device of a computer. The hardware specifications of a computer will vary depending on what an individual user will be doing with it. A person that wants to use their computer for graphically intense games or video editing will need a totally different configuration than somebody that just wants to .
