In 2001, Tim Berners-Lee became a Fellow of the Royal Society.
Berners Lee is a British computer scientist who invented the World Wide Web. Tim Berners-Lee is the primary inventor of the World Wide Web, the system of text links that made the Internet accessible to mass audiences. Lee wrote the original Web software himself in 1990 and made it available on the Internet in 1991. He joined MIT's Laboratory for Computer Science in 1994 and remains a leading authority on Internet issues. His 1999 book Weaving the Web described the Web's birth and growth. In 2003, Queen Elizabeth II announced that Berners-Lee would be made a Knight Commander of the Order of the British Empire.
In 2004, Berners-Lee was awarded the first Millennium Technology Prize, a Finland-based award for excellence which carries a cash prize of one million Euros.
The 4 Generations Of Computers
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.
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
The Second Gen
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.
The Third Gen
The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
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.
The Fourth Gen
The microprocessor 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 processing unit and memory to input/output controls-on a single chip.
The Fifth Gen
Ram Vs Rom
First released in 2012, the Raspberry Pi is a single-board computer created by the Raspberry Pi foundation in the United Kingdom. It was designed to be a small, cheap computer that could be used in schools to teach science to children. Since its introduction, almost four million Raspberry Pis have been sold.
These machines use a 700 MHz ARM processor, and models can come equipped with either 256MB or 512MB of RAM. They can support up to five USB 2.0 ports. Raspberry Pis may utilize a MicroSD card or flash memory (up to 4GB) for non-volatile storage, and uses HDMI for digital audio and video output. There is no on-board network interface, but they support wireless and Ethernet networking via USB.
Created by Charles W. Hull in 1984, the 3D printer is a sophisticated printing device that uses a design from a digital image to produce an identical physical object using materials such as metal alloys, polymers, or plastics.
An object's design typically begins in a computer aided design (CAD) software system, where its blueprint is created. The blueprint is then sent from the CAD system to the printer in a file format known as a Stereolithography (STL), which is typically used in CAD systems to design 3D objects. The printer then reads the blueprint in cross-sections and begin the process of recreating the object just as it appears in the computer aided design. In the picture below is an example of a 3D printer called the FlashForge.
