Asymmetric Digital Subscriber Line (ADSL) is one form of the Digital Subscriber Line technology,this is a data communications technology that enables faster data to be transmission over copper telephone lines than a conventional voiceband modem can provide. This is done by utilizing frequencies that are not used by a voice telephone called a splitter, or DSL filter, this in turn allows a single telephone connection to be used for both ADSL service and voice calls at the same time. ADSL can generally only be distributed over short distances from the central office, typically less than four kilometres (2 mi), but it has been known to exceed eightx kilometres (5 mi) if the originally laid wire gauge will allows for further distribution.

Audio Video Interleave (also Audio Video Interleaved), known by its acronym AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. Like the DVD video format, AVI files support multiple streaming audio and video, these features are very seldom used. Most AVI files also use the file format extensions developed by the Matrox Open DML group in February 1996. These files supported by Microsoft, are unofficially called "AVI 2.0".

Adobe,
Adobe Systems Incorporated is an American computer software company headquartered are in San Jose, California, USA. The company has historically focused upon the creation of multimedia and creativity software products, with a more-recent foray towards rich Internet application software development.
Adobe was founded in December 1982 by John Warnock and Charles Geschke, who established the company after leaving Xerox PARC in order to develop and sell the PostScript page description language. In 1985, Apple Computer licensed PostScript for use in its LaserWriter printers, which helped spark the desktop publishing revolution. The company aquired it's name Adobe from Adobe Creek in Los Altos, California, this creek ran behind the house of one of the company's founders. Adobe acquired its former competitor, Macromedia, in December 2005, which added newer software products and platforms such as Coldfusion, Dreamweaver, Flash and Flex to its product portfolio.
As of August 2009, Adobe Systems has 7,564 employees about 40% of whom work in San Jose. Adobe also has major development operations in most parts of the world.

The Apple II (often rendered Apple ][ or Apple //) was an 8-bit home computer,and one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.) and introduced in 1977. The Apple11is easy to use, has features and expandability that is a major technological advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists which pioneered many features that made the Apple II a commercial success. Introduced at the West Coast Computer Faire in 1977, the Apple II was among the first successful personal computers; it launched the Apple company into a successful business (and allowed several related companies to start). Throughout the years, a number of models were sold, with the most popular model remaining relatively little changed into the 1990s. By the end of production in 1993, somewhere between five and six million Apple II series computers (including about 1.25 million Apple IIGS models) had been produced

Analogue electronics or analog are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two different levels. The term "analogue" describes the proportional relationship between a signal and a voltage or current that represents the signal. The word analogue is derived from the Greek word (analogos) meaning "proportional".

A blog (a blend of the term web log) is a type of website or part of a website. Blogs are usually maintained by an individual with regular entries of commentary, descriptions of events, and other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. Blog can also be used as a verb, meaning to maintain or add content to a blog.
Most blogs are interactive, allowing other users to leave comments and even message each other via widgets on the blogs and it is this interactivity that distinguishes them from other static websites

The term broadband refers to a telecommunications signal of greater bandwidth, in some sense, than another standard or usual signal (and the broader the band, the greater the capacity for traffic). Different criteria for "broad" have been applied in different contexts and at different times. Its origin is in radio systems engineering, but was popularized after MediaOne adopted it as part of a marketing campaign in 1996 to sell their high speed data access. The slogan was "This is Broadband. This is the Way". The term has never been formally defined, even though it is used widely and has been the subject of many policy debates, and the FCC

Bitmap
Bitmap or pixmap in computer graphics, is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of bits. Now, along with pixmap, it commonly refers to the similar concept of a spatially mapped array of pixels. Raster images in general may be referred to as bitmaps or pixmaps, whether synthetic or photographic, in files or memory.
In certain contexts, the term bitmap implies one bit per pixel, while pixmap is used for images with multiple bits per pixel.

A web browser or Internet browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page,an image,a video, or other piece of content. Hyperlinks present in resources will enable users to easily navigate their browsers to related resources.
Although browsers are primarily intended to access the World Wide Web, they can also be used to access information provided by Web servers in private networks or files in file systems. Some browsers can also be used to save information resources to a file systems.

Connectivity
In an undirected graph G, two vertices u and v are called connected if G contains a path from u to v. Otherwise, they are called disconnected. If the two vertices are additionally connected by a path of length 1, i.e. by a single edge, the vertices are called adjacent. A graph connected if every pair of vertices in the graph are connected.
A connected component is a maximal connected subgraph of G. Each vertex belongs to exactly one connected component, as does each edge.
A directed graph is called weakly connected if replacing all of its directed edges with undirected edges produces a connected (undirected) graph. It is connected if it contains a directed path from u to v or a directed path from v to u for every pair of vertices u, v. It is strongly connected or it is strong if it contains a directed path from u to v and a directed path from v to u for every pair of vertices u, v. The strong components are the maximal strongly connected subgraphs.

A Compact Disc (also known as a CD) is an optical disc used to store digital data. It was originally developed to store and playback sound recordings exclusively, but later expanded to encompass data storage CD-ROM, write-once audio and data storage CD-R, rewritable media CD-RW, Video Compact Discs (VCD), Super Video Compact Discs (SVCD), PhotoCD, PictureCD, CD-i, and Enhanced CD. Audio CDs and audio CD players they have been commercially available since October 1982.
Standard CDs have a diameter of 120 millimetres (4.7 in) and can hold up to 80 minutes of uncompressed audio (700 MB of data). The Mini CD has various diameters ranging from 60 to 80 millimetres (2.4 to 3.1 in); they are sometimes used for CD singles, storing up to 24 minutes of audio or delivering device drivers.

A codec is a device or a computer program capable of encoding and/or decoding a digital data stream or signal. The word codec is a portmanteau of 'compressor-decompressor' or, more commonly, 'coder-decoder'. A codec (the program) is not be confused with a coding or compression format or standard – a format is a document (the standard), a way of storing data, while a codec is a program (an implementation which can read or write such files. In practice "codec" is sometimes used loosely to refer to formats, however.
A codec encodes a data stream or signal for transmission, storage or encryption, or decodes it for playback or editing. Codecs are used in video conferencing, streaming media and video editing applications. A video camera's analog-to-digital converter (ADC) converts its analog signals into digital signals, which are then passed through a video compressor for digital transmission and storage. A receiving device then runs the signal through a video decompressor,and then to a digital-to-analog converter (DAC) for analog display. The term codec is also used as a generic name for a video conferencing unit.

Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can also be applied to any kind of XML document, including SVG and XUL.
CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation,this includes elements such as the layout, colors, and fonts This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics,also enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design). CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) as well as Braille-based, tactile devices. While the author of a document typically links that document to a CSS style sheet, readers can use a different style sheet, perhaps one on their own computer, to override the one the author has specified.

The CMYK color model (process color, four color) is a subtractive color model,that is used in color printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some color printing such as cyan, magenta, yellow, and key (black). Though it varies by print house, press operator, press manufacturer and press run, ink is typically applied in the order of the abbreviation.
The “K” in CMYK stands for key since in four-color printing cyan, magenta, and yellow printing plates are carefully keyed or aligned with the key of the black KEY PLATE. Some sources suggest that the “K” in CMYK comes from the last letter in "black" and was chosen because B already means blue However, this explanation, , is incorrect.

Computer Operating System
An operating system (OS) is software, consisting of programs and data, that runs on computers and manages computer hardware resources and provides common services for efficient execution of various application software.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between application programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently call the OS or be interrupted by it. Operating systems are found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers.

Pre-recorded DVD discs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are known as DVD-ROM, because data can only be read and not written or erased. Blank recordable DVD discs (DVD-R and DVD+R) can be recorded once using a DVD recorder and then function as a DVD-ROM. Rewritable DVD discs (DVD-RW, DVD+RW, and DVD-RAM) can be recorded and erased many times.
DVD discs are used in DVD-Video consumer digital video format and in DVD-Audio consumer digital audio format, all so for authoring AVCHD discs. DVD discs containing other types of information, they may be referred to as DVD data discs

A domain name is an identification label that defines a realm of administrative autonomy, authority, or control in the Internet. Domain names are also hostnames that identify Internet Protocol (IP) resources such as web sites. Domain names are formed by the rules and procedures of the Domain Name System (DNS).
Domain names are used in various networking contexts and application-specific naming and addressing purposes. They are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, net and org and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users that may wish to connect local area networks to the Internet, run web sites, or create other publicly accessible Internet resources. The registration of these domain names is usually administered by domain name registrars who sell their services to the public.

In computing, a name server consists of a program or computer server that implements a name-service protocol. It maps a human-recognizable identifier to a system-internal, often numeric, identification or addressing component.
The most prominent types of name servers that are in operation today are the name servers of the Domain Name System (DNS), one of the two principal name spaces of the Internet. The most important function of these DNS servers is the translation (resolution) of humanly memorable domain names and hostnames into the corresponding numeric Internet Protocol (IP) addresses, the second principal Internet name space, used to identify and locate computer systems and resources on the Internet.

Encryption
Encryption in cryptography is the process of transforming information (plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as ciphertext). In many contexts, the word encryption also implicitly refers to the reverse process, decryption (e.g. “software for encryption” can typically also perform decryption), to make the encrypted information readable again (i.e. to make it unencrypted

Electronic mail, commonly called email, e-mail or e.mail, is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks. Some early email systems required that the author and the recipient both be online at the same time, instant messaging. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver and store messages. Neither the users nor their computers are required to be online simultaneously; they need connect only briefly, typically to an email server, for as long as it takes to send or receive messages.

A home page or homepage has various related meanings to do with web sites:
- It most often refers to the initial or main web page of a web site, sometimes called the front page (by analogy with newspapers).
- The web page or local file that automatically loads when a web browser starts or when the browser's "home" button is pressed; this is called a start page. The user can specify the URL of the page to be loaded, or may choose e.g. to re-load the most recent web page browsed.
- In the 1990s this term was also used to refer to a whole web site, particularly a personal web page (proberbly because simple web sites often consisted of just one web page).

Fixed wireless is the operation of wireless devices or systems used to connect two fixed locations (e.g., buildings) with a radio or other wireless link, such as laser bridge. Usually, fixed wireless is part of a wireless LAN infrastructure. The purpose of a fixed wireless link is to enable data communications between the two sites or buildings. Fixed wireless data (FWD) links are often a cost-effective alternative to leasing fiber or installing cables between the buildings.
The point-to-point signal transmissions occur through the air over a terrestrial microwave platform rather than through copper or optical fiber; therefore, fixed wireless does not require satellite feeds or local telephone service. The advantages of fixed wireless include the ability to connect with users in remote areas without the need for laying new cables and the capacity for broad bandwidth that is not impeded by fiber or cable capacities. Fixed wireless devices usually get their electrical power from the public utility mains, unlike mobile wireless or portable wireless devices which tend to be battery powered.

File size measures the size of a computer file. Typically it is measured in bytes with a prefix. The actual amount of disk space consumed by the file depends on the file system.
The maximum file size a file system supports depends on the number of bits reserved to store size information and the total size of the file system. For example, with FAT32, the size of one file cannot be equal or larger than 4 GiB.
Some common file size units are:
1 KiB = 1,024 bytes
1 MiB = 1,048,576 bytes
1 GiB = 1,073,741,824 bytes
1 TiB = 1,099,511,627,776 bytes
These units are often described using the terms KB, MB, GB and TB respectively.. For example, a hard disk which is described by its maker as having a capacity of 200 GB will have a capacity very close to 200 x 109 bytes. Yet, when such a disk is freshly formatted and installed in a machine running Microsoft Windows, the operating system will report the size as approximately 186 GB (this value can vary slightly depending on the exact capacity of the drive and the file system used). This is because Windows is actually reporting the size in GiB and 186 GiB is approximately equal to 200 GB.

A filename extension is a suffix to the name of a computer file applied to indicate the encoding convention (file format) of its contents.
In some operating systems (for example Unix) it is optional, while in some others (such as DOS) it is a requirement. Some operating systems limit the length of the extension (such as DOS and OS/2, to three characters) while others (such as Unix) do not. Some operating systems (for example RISC OS) do not use filename extensions. Unix accepts the separator dot as a legal character but does not give it a special recognition on the OS level.
