The First Website Ever Made

The first web page went live on August 6, 1991. It was dedicated to information on the World Wide Web project and was made by Tim Berners-Lee. It ran on a NeXT computer at the European Organization for Nuclear Research, CERN.

Algebra, The origins of

Algebra is the study of mathematical symbols and the rules for manipulating these symbols.Algebra is also known as the language through which we describe patterns.

Three form of numbers in Science

Did you know that all people can be classified into one of 10 groups- those who are familiar with binary number system and those who are not familiar with it.

Ethernet LAN Hardware

The most common type of LAN hardware is known as Ethernet. In its simplest form, it consists of a single cable with hosts attached to it through connectors, taps, or transceivers.

Hard Disk Drives Key Technological Firsts

There have been a number of important firsts in the world of hard disks over their first 40 or so years.

Industrial Trends of hard Disk

The most amazing thing about hard disks is that they both change and don't change more than most other components.

A Brief History of the Hard Disk Drive

Hard disks are one of the most important and also one of the most interesting components within the PC. They have a long and interesting history dating back to the early 1950s.

What are Microcontrollers

The situation we find ourselves today in the field of microcontrollers had its beginnings in the development of technology of integrated circuits.

History of SiC LEDs

Starting early in the twentieth century, light emission from a solid-state material, caused by an electrical power source, has been reported: a phenomenon termed electroluminescence.

Hard Disk Drive

The hard disk drive in your system is the data center of the PC. It is here that all of your programs and data are stored between the occasions that you use the computer.

Why computer are suspended?

There are many reasons why a computer is running suddenly stand still, no response to the impacts from the keyboard or mouse, or commonly called the machine “hold”.

Chemistry of the Elements

Only about 90 of the 114 presently known elements occur naturally. The remaining ones have been produced artificially by nuclear chemists using highenergy particle accelerators.

High Low Voltage Cut Out

This circuit will turn off the relay when the voltage is above or below the "set-points." You need either a variable power supply or a 12v battery and an extra 1.5v battery.

Plant needs watering circuit using One Transistor

This circuit indicates when the soil is dry and the plant needs watering.

Touch Switch using One Transistor

Your body has resistance and when a voltage is present, current will flow through your body (fingers).
