Time Berners-Lee was born 8 June 1955 (age 59). He invented the World Wide Web in 1989. He also founded and Directs the World Wide Consortium (N3C) the forum for technical development of the web. He now spends most of his time fighting for things that are right such as freedom.

Alan Turing

Alan Turing was born 23 June 1912 and died 7 June 1954 at aged 41. He was a British pioneering computer scientist, mathematician, logician, cryptanalyst, philosopher, mathematical biologist, and marathon and ultra distance runner. He also helped crack the German Enigma Code which helped the British win the war.

The Five Generations of Computers

The First Generation (1941 - 1956)

World War II gave rise to numerous developments and started off the computer age. Electronic Numerical Integrator and Computer (ENIAC) was produced by a partnership between University of Pensylvannia and the US government. It consisted of 18,000 vacuum tubes and 7000 resistors. In first generation computers, the operating instructions or programs were specifically built for the task for which computer was manufactured.

The Second Generation (1956 - 1963)

The invention of Transistors marked the start of the second generation. These transistors took place of the vacuum tubes used in the first generation computers. First large scale machines were made using these technologies to meet the requirements of atomic energy laboratories. Second generation computers also started showing the characteristics of modern day computers with utilities such as printers, disk storage and operating systems. Many financial information was processed using these computers.

The Third Generation (1964-1971)

Although transistors were great deal of improvement over the vacuum tubes, they generated heat and damaged the sensitive areas of the computer. It combined electronic components onto a small silicon disc, made from quartz. More advancement made possible the fittings of even more components on a small chip or a semi conductor. Also in third generation computers, the operating systems allowed the machines to run many different applications. These applications were monitored and coordinated by the computer's memory.

The Fourth Generation of Computers (1975-Present)

The fourth generation computers started with the invention of Microprocessor. The Microprocessor contains thousands of ICs. Ted Hoff produced the first microprocessor in 1971 for Intel. It was known as Intel 4004. The technology of integrated circuits improved rapidly. The LSI (Large Scale Integration) circuit and VLSI (Very Large Scale Integration) circuit was designed. It greatly reduced the size of computer. The size of modern Microprocessors is usually one square inch. It can contain millions of electronic circuits.

The Fifth Generation of Computers (Present & Beyond)

Scientists are working hard on the 5th generation of computers with quite a few breakthroughs. It is based on the technique of artificial intelligence (AI). Computers can understand spoken words & imitate human reasoning. Can respond to its surroundings using different types of sensors. Scientists are constantly working to increase the processing power of computers. They are trying to create a computer with real IQ with the help of advanced programming and technologies. IBM Watson computer is one example that outsmarts Harvard University Students. The advancement in modern technologies will revolutionize the computer in future.

TYPES OF INPUT DEVICES

An input is something that you use when you tell a computer what to do. Here are a few examples of input devices.

-keyboard
-touch screen

-touchpad

-microphone

TYPES OF OUTPUT DEVICES

An output is something that comes out of a computer. here are a few examples of output devices.

-speakers

-headphones

-monitor

-projector

HARDWARE - COMPUTER COMPONETS

Drives

A driver is software that allows your computer to communicate with hardware or devices. Without drivers, the hardware you connect to your computer. For example, a video card or a webcam will not work properly.

Monitors

A computer monitor is an electronic device that shows pictures. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.

CPU's

The CPU (also know as the Central Processing Unit) is a part of a computer system that is commonly referred to as the "brains" of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program.

RAM

RAM is an acronym for random access memory, a type of computer memory that can be accessed randomly, that is any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.

ROM

Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory (RAM), ROM retains its contents even when the computer is turned off. ROM is referred to as being non volatile, whereas RAM is volatile.

Motherboards

A motherboard (sometimes known as the main board, system board, planar board or logic board) is the main printed circuit board (PCB) found in computers and other expandable systems.

Inputs

In computing, an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance.
Big image

Outputs

An 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.

Touch Screens

A touch screen is a computer display screen that is also an input device. The screens are sensitive to pressure and a user interacts with the computer by touching pictures or words on the screen.

RASPERRY PI

The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. The original Raspberry Pi and raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14, RS Components and Egoman. these companies sell the Raspberry Pi online. In early February 2015, the next-generation Raspberry Pi, Raspberry Pi 2 was officially announced.

3D PRINTING

3D printing is any of various processes used to create a three-dimensional object. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3d model or other electronic data source.

Evaluation

I think you did very well! There was barely any copy and pasting, no spelling or grammar mistakes, you couldn't get board reading it. you used operate images and wrote about key information, also you used links to give more information to the reader. But the most obvious fault is your background, it is not relevant.


I would give your work a 9/10 because of all the reasons above.
