History of ComputING

Originally, the term “computer” referred to a person who performed numerical calculations (a human computer) often with the aid of a mechanical calculating device. Examples of early mechanical computing devices included the abacus, the slide rule, etc. In 1623 Wilhelm Schickard built the first mechanical calculator and thus became the father of the computing era.

However, none of those devices fit the modern definition of a computer because they could not be programmed. In 1801, Joseph-Marie Jacquard developed a loom in which the pattern being woven was controlled by punched cards. The series of cards could be changed without changing the mechanical design of the loom. This was a landmark point in programmability. In 1837, Charles Babbage was the first to design a fully programmable mechanical computer that he called “The Analytical Engine”. In 1890, the United States Census Bureau used punch cards and sorting machines designed by Herman Hollerith to handle the flood of data from the decennial census mandated by the Constitution. Hollerith’s company eventually became the core of IBM. IBM developed punch card technology into a powerful tool for business data processing and produced an extensive line of specialized unit record equipment.

More powerful and flexible computing devices were constructed in the 1930s and 1940s, gradually adding the key features that are seen in modern computers. Vacuum tube computers were in use throughout the 1950s, but were largely replaced in the 1960s by transistor computers, which were smaller, faster, and cheaper, used less power and were more reliable. By the 1970s, the adoption of integrated circuit technology and the creation of microprocessors such as the Intel 4004 caused another leap in size, speed, cost and reliability. By the 1980s, computers had become sufficiently small and cheap to replace simple mechanical controls in domestic appliances such as washing machines. Around the same time, computers became widely accessible for personal use by individuals in the form of personal computers. In conjunction with the widespread growth of the Internet since the 1990s,   personal computers are becoming as common as the television and the telephone and almost all modern electronic devices contain a computer of some kind.

The future of computers seems to be in Cheap Laptops and small netbooks or handheld smartphones. It is predicted by many market analysts that personal desktop computers will soon be as obsolete as the room-sized computers first built back in the 1940’s.

Hardware of a modern Personal Computer:

1 – monitor;

2 – motherboard;

3 – CPU (microprocessor);

4 – RAM memory

5 – expansion cards;

6 – power supply;

7 – optical disc drive;

8 – hard disk

9 – keyboard;

10 – mouse.

A minimal setup of a typical contemporary desktop computer would be: a computer case with power supply (usually sold together), a motherboard, a processor with a heat sink and a fan (usually sold together); at least one memory card, a mass storage, a keyboard and a mouse for input, a monitor for output.

The motherboard (or mainboard) is the primary circuit board within a personal computer. It connects everything together. The central processing unit, or CPU, is that part of a computer which executes software program instructions. Nearly all PCs contain a type of CPU known as a microprocessor. The microprocessor is often plugged into the motherboard using one of many different types of a socket.

The mass storage is connected to the motherboard with cables and can be installed in the computer case or in a separate case. The mass storage can be: a hard disk, a floppy drive or a Zip drive (both with removable media), an optical drive (CD or DVD, removable, usually read-only). The operating system (e.g.: Microsoft Windows, Mac OS, Linux or many others) can be located on either of these, but typically it’s on one of the hard disks. A live CD is also possible, but it is very slow and is usually used for installation of the OS, demonstrations, or problem solving.

The memory card(s) and video card are mounted directly onto the motherboard in expansion slots. The video card – otherwise called a graphics card, graphics adapter or video adapter – processes and renders the graphics output from the computer to the computer display, also called the visual display unit (VDU), and is an essential part of the modern computer.

The keyboard and the mouse are external and connected to the back plate of the motherboard. The monitor is also connected to the back plate, not (usually) directly to the motherboard, but to a connector in the graphics card.

A typical computer also has a network card, a modem and possibly a router. Common additions connected on the outside (peripherals) are: a printer, a scanner, a web cam, speakers, a microphone, a headset, a card reader, gaming devices, such as a joystick.

Nowadays laptop computers or simply laptops (also called notebooks) are in wide use. They are small personal computers designed for mobility. Usually all of the interface hardware needed to operate the laptop, such as parallel and serial ports, graphics card, sound channel, etc., is built-in to a single unit. They contain batteries to facilitate operation without a readily available electrical outlet.
