In C language, the formatting character should be preceded by the symbol %.

Windows 7 is the first version of Windows to ship with more fonts for non-Latin scripts than for Latin-based scripts. One major area of improvement is for the languages of India. earlier windows have nine (9) fonts for Indian languages that shipped in Vista, Windows 7 adds forty (40) more.

Windows 7 will now include multiple fonts (often in multiple weights) for each of the official languages of India.

The most crucial portion of any computer is the Central Processing Unit (CPU). The CPU is the brain of the computer where most calculations take place.

A Wide Area Network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using private or public network transports.

Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations.

In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location.

The CPU (Central Processing Unit) is commonly referred to as the “brains” of a computer since it carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The CPU is also known as the processor or microprocessor.

A firewall is a computer appliance or router that sits between the trusted and untrusted systems. It enables a computer to be connected safely to an untrustworthy network.

It is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.

As the name suggests, read-only memory, or ROM, stores information that can only be read. It contains the basic instructions for what needs to happen when a computer is powered on. This is typically referred to as the firmware of a computer.

The firmware represents the basic code to get the computer started. Once the computer is up and running, the CPU takes over. Firmware is also referred to as BIOS, or basic input/output system.

In computer science, LIFO refers to the way items stored in some types of data structures are processed. A LIFO structure can be illustrated with the example of a stack of trays.

The term in computing generally refers to the abstract principles of list processing and temporary storage, particularly when there is a need to access the data in limited amounts, and in a certain order.

Clip art, in the graphic arts, refers to pre-made images used to illustrate any medium.

Today, clip art is used extensively in both personal and commercial projects, ranging from home-printed greeting cards to commercial candles. Clip art comes in many forms, both electronic and printed.

However, most clip art today is created, distributed, and used in an electronic form.

Text can be aligned with one or both edges (or insets) of a text frame. Text is said to be justified when it is aligned with both edges. We can justify text in a paragraph including the last line.

WLL stands for Wireless in local loop, is a term for the use of a wireless communications link as the “last mile / first mile” connection for delivering plain old telephone service (POTS) and/or broadband Internet to telecommunications customers.

A worm is a process that uses the spawn mechanism to clobber system performance.

The worm spawns copies of itself, using up system resources and perhaps locking out the system used by all other processes. On computer networks, worms are particularly potent, since they may reproduce themselves among systems and thus shut down the entire network.

Such an event occurred in 1988 to UNIX systems on the internet.

Microencapsulation is one of the several technologies used in Electronic printing. It is widely used in “carbonless” carbon paper and “scratch-and-sniff” cologne and perfume advertisements in magazines.

This technology involves the usage of millions of transparent fluid-filled capsules containing microscopic particles (Chemistry By Steven Zumdahl, Susan Zumdahl, p. 488).

One of the common forms of representing remote sensing data as the information is in the form of thematic maps, by means of visual or computer classification.

However, thematic maps are not an end in themselves and are only the starting point for a variety of applications to which remote sensing data can be potentially used.

The World Wide Web (abbreviated as WWW or W3, commonly known as the Web), is a system of interlinked hypertext documents accessed via the Internet.

Using concepts from his earlier hypertext systems like ENQUIRE, British engineer, computer scientist and at that time employee of CERN, Sir Tim Berners-Lee, now Director of the World Wide Web Consortium (W3C), wrote a proposal in March 1989 for what would eventually become the World Wide Web.

Associative memory in computer organization is when memory is accessed through content rather than through a specific address. Associative memory is also known as associative storage, associative array or content-addressable memory, or CAM.

Associative memory is found on a computer hard drive and used only in specific high-speed searching applications.

A central processing unit (CPU), also known as processor, consists of two main components: Arithmetic Logic Unit (ALU), which performs arithmetic and logical operations and the Control Unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.ALU is a fundamental building block of CPU.

Arithmetic and Logic Unit (ALU) performs Arithmetic operations and comparisons.

The size of a display is usually by monitor manufacturers given by the diagonal, i.e. the distance between two opposite screen corners. This method of measurement is inherited from the method used for the first generation of CRT television when picture tubes with circular faces were in common use.

Being circular, only their diameter was needed to describe their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangle was equivalent to the diameter of the tube’s face.

A modem turns the digital data of a personal computer into modulated electrical signals in the voice frequency range of a telephone channel. These signals can be transmitted over telephone lines and demodulated by another modem at the receiver side to recover the digital data.
