What he did to become famous?

Timothy John Berners Lee was born on 8 June 1955 and grew up in London. He studied physics at Oxford University and became a software engineer. Tim Berners-Lee is a computer scientist and as one he invented the internet (also known as the World Wide Web) in 1989.

History of computers - "Past to Present & Beyond"

What will the 5th Generation of Computers be Like?

Parallel Processing

  • In fifth-generation computers, the program instructions will be divided among multiple processors of the computers, so that each processor will have fewer tasks to perform, and thus, the program will run in less time. Although the parallel processing system has been applied to some fourth-generation computers, they cannot be called fifth-generation computers because they do not run full artificial intelligence operations.

Speech Recognition

  • Speech recognition is one of the most important features of fifth-generation computers. Although this technology has been used in some computers since the 1990s, it is limited in its applications and does not support the system completely. In addition to that, speech recognition is recognized as just an added feature, although manual input is the main method of operating the computers. Fifth-generation computers are yet to come with fully supported speech recognition features.

Pattern Recognition

  • With an aim to minimize human effort and maximize computer application, pattern recognition systems will be an integral part of fifth-generation computers. This technology will help in tracking similar patterns in computing habits by using the information gathered to save you time and effort.

Understanding of Natural Human Language

  • There is a multitude of computer programming languages, including A+, C++, BASIC, FoxPro, Java and Cobol, that are used for carrying out tasks on computers. However, none have the ability to understand the natural human language. Scientists aim at creating fifth-generation computers that will be able to understand languages used by humans, so that time and effort will be saved to a large extent.

Advancements in Semiconductor Technology

  • Chips have been built that consist of millions of components, and semiconductor memory has become standardized on all computers manufactured now. But advancements are yet to be made in this field, and then, speed of information traffic will be enhanced significantly.

Imput of Computers

Input Device Defined

An input device for a computer allows you to enter information. The most fundamental pieces of information are keystrokes on a keyboard and clicks with a mouse. These two input devices are essential for you to interact with your computer. Many other input devices exist for entering other types of information, such as images, audio and video.

Output of Computers

Any information that has been processed by and sent out from a computer or similar device is considered output. A simple example of output is anything you view on your computer monitor. That data is then printed onto a piece of paper; both are forms of output.

A Hard Drive

A hard disk drive (sometimes abbreviated as Hard drive, HD, or HDD) is a data storage device. The hard disk was first introduced on September 13, 1956 and consists of one or more platters inside of an air-sealed casing. Internal hard disks reside in a drive bay and connect to the motherboard using an ATA, SCSI, or SATA cable, and are powered by a connection to the PSU (power supply unit). Below is a picture of what the inside of a hard drive looks like for a desktop and laptop hard drive.

RAM (pronounced ramm) 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.


Pronounced see-dee-rom. Short for Compact Disc-Read-Only Memory, a type of optical disk capable of storing large amounts of data -- up to 1GB, although the most common size is 650MB (megabytes). A single CD-ROM has the storage capacity of 700 floppy disks, enough memory to store about 300,000 text pages.

Raspberry Pi

The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.

3D Printer

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.

Have fun creating anything wanted!

If you've ever taken the case off of a computer, you've seen the one piece of equipment that ties everything together -- the motherboard. A motherboard allows all the parts of your computer to receive power and communicate with one another.

Motherboards have come a long way in the last twenty years. The first motherboards held very few actual components. The first IBM PC motherboard had only a processor and card slots. Users plugged components like floppy drive controllers and memory into the slots.

Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades.
