Pentium M

The first Pentium M computer was introduced in March 2003 and is based on x86 microprocessor architecture. During later modification the Pentium M is not a low-power version of the desktop-oriented Pentium 4, but instead a heavily modified version of the Pentium III design. It is optimised for power efficiency with the purpose of extending notebook computer battery life. Running with very low average power consumption and much lower heat output than desktop processors, the Pentium M runs at a lower clock speed than the contemporary Pentium 4 desktop processor series, but with similar performance (e.g. a 1.6 GHz Pentium M can typically attain the performance of a 2.4 GHz Northwood Pentium 4 (400 MHz FSB, 100 MHz quad-pumped) with no Hyper-Threading Technology).

Central Processing Unit

Also Known as CPU.

A central processing unit refers to part of a computer that interprets and carries out, or processes, instructions and data contained in the software. The more generic term processor can be used to refer to a CPU as well. Microprocessors are CPUs that are manufactured on integrated circuits, often as a single-chip package. Since the mid-1970s, these single-chip microprocessors have become the most common and prominent implementations of CPUs, and today the term is almost always applied to this form.

The term "Central processing unit" is, in general terms, a functional description of a certain class of programmable logic machines. This broad definition can easily be applied to many early computers that existed long before the term "CPU" ever came into widespread usage, yet the term and its acronym have been in use at least since the early 1960s.

Flash memory

Flash memory, or more precisely, NAND flash memory chips, stores data on a semiconductor. It is mostly used in the form of USB flash drives to transfer data from one PC to another, or as memory cards that record hundreds of photos in digital cameras. Apple uses flash memory as a substitute for a hard disk drive so it can make its music player only a quarter-inch thick.
Manufacturer prices are starting to rise even though historically the price of flash memory has fallen about 40 percent a year.

The Portable Hard Drive

The portable hard drive is a higher capacity variant of the flash drive. Although this device is somewhat larger than the flash drive, this device is still convenient to take to businesses and to transfer large amounts of data. Shape vary and are based on USB; the USB cord is retractable in some for increased portability. The most common are those based on MicroDrives. They aren't much larger than the drive they contain, and often have retractable USB plugs. They are meant to have the same practicality and ease of use of flash drives (Mass Storage Class drivers and portability), but they are still based on an actual (albeit micro-sized) hard disk with moving heads and spinning platters, so they are much less tolerant of abuse.

Monitor

What is it?

A computer display, monitor or screen is a computer peripheral device capable of showing still or moving images generated by a computer and processed by a graphics card. Monitors generally conform to one or more display standards. Sometimes the name "display" is preferred to the word "monitor". Computer displays are sometimes called heads, especially when talking about how many are connected to a computer. Once an essential component of a computer terminal, computer displays have long since become standardized peripherals in their own right.

Keyboard

A keyboard is a peripheral modelled after the typewriter keyboard. Keyboards are designed for the input of text and characters, and also to control the operation of the computer. Physically, computer keyboards are an arrangement of rectangular or near-rectangular buttons, or "keys". Keyboards typically have characters engraved or printed on the keys; in most cases, each press of a key corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously, or in sequence; other keys do not produce any symbol, but instead affect the operation of the computer, or the keyboard itself.

Roughly 50% of all keyboard keys produce letters, numbers or signs (characters). Other keys can produce actions when pressed, and other actions are available by simultaneously pressing more than one action key.
