THE PEOPLE
Tim Burners Lee
Tim Burners Lee is the director of the world wide web consortium which oversees the webs continued development he is also the founder of the world wide web foundation and is a senior researcher and holder of the founders chair at the MIT computer science and artificial intelligence labrortary.
in 2004 he was knighted by queen elizabeth II for his pioneering work.
Alan Turing
Alan Turing was born on 23 June, 1912, in London. His father was in the Indian Civil Service and Turing's parents lived in India until his father's retirement in 1926. Turing and his brother stayed with friends and relatives in England. Turing studied mathematics at Cambridge University, and subsequently taught there, working in the burgeoning world of quantum mechanics. It was at Cambridge that he developed the proof which states that automatic computation cannot solve all mathematical problems. This concept, also known as the Turing machine, is considered the basis for the modern theory of computation.
The 4 Generations Of The Computers
1st generation
The first computers used vacuum tubes for circuitry and magnetic drums for memory , and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
2nd generation
Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output
3rd generation
Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system , which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.
4th generation
The miocropresser brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central procesing unit and memory to input/output controls—on a single chip.
fith generation
the fifth generation computer system project was an initiative by Japan's ministry international trade and industry , begun in 1982, to create a computer using massively parallel computing /processing. It was to be the result of a massive government/industry research project in Japan during the 1980s. It aimed to create an "epoch-making computer" with-supercomputer-like performance and to provide a platform for future developments in artificial intelligence. There was also an unrelated Russian project also named as fifth-generation computer
inputs and outputs
A input is a keyboard a touch screen or a mouse and will enter information to a output device outputs give out infomation
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.
ram / 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 isvolatile 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.
moniters
Alternatively referred to as a video display terminal and video display unit , a monitor encompasses a display screen for video images and casing that holds it. In its most common usage, monitor refers only to devices that contain no electronic equipment other than what is essentially needed to display and adjust the characteristics of an image.
motherboards
The motherboards 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.
cpu
The Central Processing Unit (CPU) is responsible for interpreting and executing most of the commands from the computer's hardware and software
rassberry pi
what is a raspberry pi well it is The Raspberry Pi is a low cost, credit sized computer card that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.
Just Bought A Raspberry Pi? 11 Things You Need To Know
Evaluation, Ffion Evans
You have got a lot of info about different topics. It is very detailed. I like how you have got links and videos in the flyer. The background could be a bit more relevant to the topic. Besides that the layout is good and you have put a lot of effort into it. Try not to copy and paste everything.
