Computer hardware

Hardware is a comprehensive term for all of the physical parts of a computer, as distinguished from the data it contains or operates on, and the software that provides instructions for the hardware to acoomplish tasks. The boundary between hardware and software is slightly blurry - firmware is software that is "built-in" to the hardware, but such firmware is usually the province of computer programmers and computer engineers[?] in any case and not an issue that computer users need to concern themselves with.

A typical computer (Personal Computer, PC) contains in a desktop or tower case the following parts:



Motherboard which holds the CPU, main memory and other parts, and has slots for expansion cards

power supply - a case that holds a transformer, voltage control and fan

storage controllers, of IDE, SCSI or other type, that control hard disk , floppy disk, CD-ROM and other drives; the controllers sit directly on the motherboard (on-board) or on expansion cards

graphics controller that produces the output for the monitor

the hard disk, floppy disk and other drives for mass storage

interface controllers (parallel, serial, USB, Firewire) to connect the computer to external peripheral devices such as printers or scanners

Computer software

Computer software (often called just software) is made of one or more computer programs. Sometimes it means one specific program, or it can mean all the software on a computer, including the applications and the operating system. Applications are programs that do a specific thing, such as a game or a word processor. The operating system (Mac OS, Windows 7, Windows XP, Linux, etc) is software that helps the applications run, and controls the display and the keyboard.

INTERNET
The Internet is generally defined as a global network connecting millions of computers. More than 190 countries are linked into exchanges of data, news and opinions. It is a vast computer network linking smaller computer networks worldwide (usually preceded by the). The Internet includes commercial, educational, governmental, and other networks, all of which use the same set of communications protocols.

ELECTRICITY AND MAGNETISM




6º. Unit 8.

ELECTRICITY

  Electricity has been known since ancient times, but scientists could not make use of it safely until the eighteenth century. Thomas Edison's invention of the electric lightbulb in 1879 sparked the demand for electric power that continues to this day, ultimately resulting in the need for legislative and regulatory controls on the electric-power-generating industry.

 

 Electrical charge.

Static electricity

Static electricity is the build up of an electrical charge on the surface of an object. It's called "static" because the charges remain in one area rather than moving or "flowing" to another area. We see static electricity every day. It can even build up on us. For example, when we rub our feet on the carpet and then zap something when we touch it. That is static electricity that we have built up on the surface of our skin discharging onto another object. We also see it when our hair gets charged and sticks straight up or when our pant legs keep sticking to our legs. This is all static electricity that has built up on the surface of an object.

What is current electricity?

Electric current in simple terms are electrons in motion along a path, regardless of the number of electrons flowing. The path may be a conductor such as copper, silver and aluminium. Free electrons can be forced to move from one region of the conductor to the other.

MAGNETISM


Most people are familiar with magnets primarily as toys, or as simple objects for keeping papers attached to a metal surface such as a refrigerator door. In fact the areas of application for magnetism are much broader, and range from security to health care to communication, transportation, and numerous other aspects of daily life. Closely related to electricity, magnetism results from specific forms of alignment on the part of electron charges in certain varieties of metal and alloy.


           3. Magnetic pole

 1. Either of two small regions which are located respectively in the polar areas of the northern and southern hemispheres and toward which a compass needle points from any direction throughout adjacent regions; also :  either of two comparable regions on a celestial body

2 :  Either of the poles of a magnet.
