The History of Computing

Sir Tim Berners-Lee

Sir Tim Berners-Lee is a famous computer scientist, best known as the inventor of the 'World Wide Web'. (1989) He was knighted by Queen Elizabeth in 2004. His invention really did change he world.

Alan Turing

Alan Mathison Turing, was born 23 June 1912.He was a British pioneering computer scientist, mathematician, logician, cryptanalyst, philosopher, mathematical biologist, and marathon and ultra distance runner. He was highly influential in the development of computer science providing a formalisation of the concepts of "algorithm" and "computation" with the Turing Machine, which can be considered a model of a general purpose computer.Turing is widely considered to be the father of theoretical computer science and artificial intelligence.

What is a Monitor?

A monitor or a display is an electronic visual display for computers. The monitor comprises the display device, circuitry and an enclosure. The display device in modern monitors is typically a thin film transistor liquid display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size.

Originally, computer monitors were used for data processing while television receivers were used for entertainment. From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality.

What is a Drive?

A drive is a medium that is capable of storing and reading information that is not easily removed like a disk. The picture is an example of different drives listed in Microsoft Windows My computer.

What is a CPU?

Alternatively referred to as the brain of the computer, processor, central processor, or microprocessor, the CPU (pronounced as C-P-U), short for Central Processing Unit, was first developed at Intel with the help of Ted Hoff in the early 1970's. The computer CPU is responsible for handling all instructions it receives from hardware and software running on the computer.

Ram and Rom

There is one major difference between a ROM and a RAM chip. A ROM chip is non-volatile storage and does not require a constant source of power to retain information stored on it. When power is lost or turned off, a ROM chip will keep the information stored on it. In contrast, a RAM chip is volatile and requires a constant source of power to retain information. When power is lost or turned off, a RAM chip will lose the information stored on it.

What is a Motherboard?

Alternatively referred to as the mb, mainboard, mobo, mobd, backplane board, base board, main circuit board, planar board, system board, or a logic board on Apple computers. The motherboard is a printed circuit board that is the foundation of a computer, located at the bottom of the computer case. It allocates power to the CPU, Ram and all other computer hardware components. Most importantly, the motherboard allows hardware components to communicate with one another.

3D Printing

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.


great Info I think there is a bit of copy an paste going on but the grammar is correct the back ground is very relevant so well done your video's are quite boring and pictures are unique I rate it 7 out of 10.
