The motherboard is the primary circuit board within a personal computer. Many other components are connected directly or indirectly to the motherboard. Motherboards usually contain one or more CPUs, supporting circuitry – usually integrated circuits (ICs) – providing the interface between the CPU memory and input/output peripheral circuits, main memory, and facilities for initial setup of the computer immediately after power-on.

A computer is an electronic machine that processes information – in other words, an information processor: it takes in raw information (or data) at one end, stores it until it’s ready to work on it, chews and crunches it for a bit, then spits out the results at the other end. 1_______. Taking in information is called input, storing information is better known as memory, chewing information is also known as processing, and spitting out results is called output.
Your keyboard and mouse, for example, are just input units – ways of getting information into your computer that it can process. 2_______. Your computer probably stores all your documents and files on a hard-drive: a huge magnetic memory. But smaller, computer-based devices like digital cameras and cellphones use other kinds of storage such as flash memory cards. As for output, your computer almost certainly has a screen and probably also stereo loudspeakers. 3_______. Your computer’s processor (sometimes known as the central processing unit) is a microchip buried deep inside. 4_______. That’s why your computer has a little fan blowing away – to stop its brain from overheating!

CPU or Central Processing Unit is that part of a computer which executes software program instructions. In older computers this circuitry was formerly on several printed circuit boards, but in PCs it is a single integrated circuit. Nearly all PCs contain a type of CPU known as a microprocessor. The microprocessor often plugs into the motherboard using one of many different types of sockets. IBM PC compatible computers use an X86-compatible processor, usually made by Intel, AMD, VIA Technologies or Transmeta.

The study of the nucleus of an atom is known as nuclear physics. As a result of this study, scientists have discovered ways of splitting the nucleus to release huge amounts of energy. One nucleus is split, causing many others to split, in what is called a nuclear chain reaction. A controlled nuclear reaction inside a power station can be used to provide heat and light for our homes.

You put pressure on something when you apply a force to it. The amount of pressure depends on two things: the size of the force, and, more importantly, the size of the area on which it is applied. The smaller the area, the greater the pressure. This principle explains why thin stiletto heels sink into wooden floors and damage them. It also explains why a camel’s large, flat feet prevent it from sinking into the sand in the desert.

Isotopes are different forms of the same element. They have identical chemical properties and occupy the same place in the periodic table. The word “ isotope” means “same place”. It is their physical properties that differ, because their atoms (tiny particles) have different masses. Each “isotopic form” has a different number of neutrons, in the nucleus of its atoms, which gives it a different mass. Hydrogen gas, for example, can exist naturally in three isotopic forms: common hydrogen, heavy hydrogen, and radioactive hydrogen.
