What is Computer Hardware ?

what is computer hardware
The definition of Computer hardware is defined here. Computer hardware is the physical components of a computer such as CPU, Monitor, Keyboard, Graphics Card, Sound Card, Speakers, Motherboard, Storage devices, etc. Hardware refers to the physical elements of a computer. A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer. Without any hardware, your computer would not exist, and software could not be used. The hardware device like Logitech webcam allows users to take videos or pictures, and transmit them over the Internet. This is more about What is computer hardware.

How Computer Works


How Computer Works:

Today we use Computer having different types of properties and can perform millions of tasks in seconds. This is only possible due to complex architecture and reason behind how computer works. There are different types of hardware components assembled to make a single computer system. The major hardware and software responsible for working nature of Computers are illustrated below.
  
      CPU (Central Processing Unit)

How Computer Works
This hardware is called as the Brain of Computers. The CPU does the active "running" of code, manipulating data, while the other components have a more passive role, such as storing data. The computer does its primary work in a part of the machine, a control centre that converts data input to information output. This control centre called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions.

What is Computer Introduction to Computer SystemToday, Computer is widely used and we must know what is Computer Introduction to Computer System. A Computer is an electronics device that accepts input, process data and produce output. A Computer is a programmable device that can store, retrieve and process data. An Input can be a single word or digit or sentence. Same is the case with output. But processing input data depends upon the program stored in Computer memory. In modern days, we see personal Computer, Laptops in every house. But several years ago no such personal Computers was there. A simple mechanical device like Abacus and Slide rule acts as simple Computer.


History of Computer


History of Computer

We can better understand the History of Computer by learning sequences from Pre 20th century till now. Earlier Computer was not so small or compact or portable. Computers were initially large machines that could fill entire room.
The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers. ENIAC was also the first machine to use more than 2,000 vacuum tubes, using nearly 18,000 vacuum tubes.

INTRODUCTION

Computer Science Major Branches Definition
Computer science, theoretical study, experimentation, and engineering that form the basis for computer design and use— devices that process information automatically. Computer science traces its roots to the work of Charles Babbage, an English mathematician, who first proposed a programmable mechanical calculator in 1837. Computer science was not generally distinguished as separate from mathematics and engineering until the advent of digital electronic computers in the 1940s. It has since sprouted numerous research branches that are unique to the discipline.

I INTRODUCTION

Artificial Intelligence (AI), the study and engineering of intelligent machines capable of performing arts constant varieties of functions that characterize human thought. The idea of AI dates from times of yore, however the arrival of digital computers within the twentieth century brought AI into the realm of risk. AI was planned as a field of engineering science within the mid-1950s. The term AI has been applied to laptop programs and systems capable of performing arts tasks additional complicated than simple programming, though still removed from the realm of actual thought. whereas the character of intelligence remains elusive, AI capabilities presently have extensive applications in such areas as information science, laptop recreation, national security, electronic commerce, and diagnostic systems.
