What is a PDF file?

2012-10-01T23:05:00.000-07:00

PDF (Portable Document Format) is a file format developed by Adobe as a means of distributing compact, platform-independent documents. It is superficially similar to HTML; a PDF document may contain images and text, as well as hyperlinks. However, as PDF is based on a variant of PostScript, each document is self-contained, packing text, graphics, and fonts into a single file. Basically Ebook page making use this format.

You can use Adobe Acrobat Writer to create PDF files, and you can view PDF files either with Adobe Reader or via a web browser with the PDF Viewer plug-in.

Additionally, Mac OS X offers built-in support for creating PDF files and includes a free application called Preview for viewing PDF files.

Processor

2011-06-18T10:07:00.000-07:00

A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The processor is process our input command and display result by VDU. The term processor has generally replaced the term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor. The central processing unit (CPU) is the section of a computer system that carries out the commands of a computer program, and is the primary element carrying out the functions of the computer or other processing device. The central processing unit carries out each instruction of the program in sequence, to perform the basic arithmetical, logical, and input/output operations of the system. This term has been in use in the computer industry at least since the early 1960s. The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same.

There is and has been many processors on the market, running at many different speeds. The speed is precise in Megahertz or MHz. A single MHz is a calculation of 1 million cycles per second (or computer instructions), so if you have a processor running at 2000 MHz, then your computer is running at 2000,000,000 cycles per second, which in more basic terms is the amount of instructions your computer can carry out. Another important abbreviation is Gigahertz or GHz. A single GHz or 1 GHz is the same as 1000 MHz . For a bit confusing, so here is a simple conversion :

1000 MHz (Megahertz) = 1GHz (Gigahertz) = 1000,000,000 Cycles per second (or computer instructions).

Motherboard Components

2011-06-16T09:18:00.000-07:00

# sockets (or slots) in which one or more microprocessors may be set up.

# slots into which the system's main memory is to be installed (typically in the form of DIMM modules containing DRAM chips)

# a chipset which forms an interface between the CPU's front-side bus, main memory, and peripheral buses

# non-volatile memory chips (usually Flash ROM in modern motherboards) containing the system's firmware or Basic Input and output system (BIOS)

# a clock generator which produces the system clock signal to bring into line the various components

# slots for expansion cards (these interface to the system via the buses supported by the chipset)

power connectors, which receive electrical power from the computer power supply and distribute it to the CPU, chipset, main memory, and expansion cards.

What is mother board ?

2011-06-15T08:06:00.000-07:00

The main circuit board of a microcomputer is mother board. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the Central processing Unit, Basic input and output system, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are know as the motherboard’s chip set.

An important component of a motherboard is the microprocessor's supporting Chip set, which provides the supporting interfaces between the CPU and the various buses and external components. This chip set determines, to an extent, the features and capabilities of the motherboard.

Computer Hardware means all components of computer. The components you can actually see and touch, and would likely break if you threw it out a fields is hardware. As example Key board, Mouse, Monitor, CPU etc is parts of computer or computers hardware. Not every system (computer) has exactly the same hardware. One of the definitions of 'hardware' according to Webster's dictionary is 'major items of equipment or their components used for a particular purpose'.
