What is cache?

In computing, a cache is a component that stores data so future requests for that data can be served faster, the data stored in a cache might be the results of an earlier computation or the duplicates of data stored elsewhere. A cache, while a cache miss occurs when it cannot. Cache hits are served by reading data from the cache, which is faster than recomputing a result or reading from a slower data store; thus the more requests can be served from the cache, the faster the system performs.

What is Bug?

A bug or software bug is an error, flaw, failure, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.

What is Buffer?

In computer science, a buffer is a region of physical memory storage used to temporarily store data while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers). However, a buffer may be used when moving data between processes within a computer.

What is Browsing Software?

Browsing software 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/URL) and maybe a web page, image, video, or another piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

What is Browsing?

Browsing is a kind of orienting strategy. It is supposed to identify something of relevance for the browsing organism. When used about human beings it is a metaphor taken from the animal kingdom. It is used, for example, about people browsing open shelves in libraries or browsing databases or the Intenet. In Library and information science, it is an important subject, both purely theoretically and as applied science aiming at designing interfaces that support browsing activities for the user.

What is Broadcasting?

Broadcasting is the distribution of audio and or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in one too many models. The term broadcasting derived from the method of sowing seeds in a field by casting them broadly about was originated from methods using the wired transmission (as in telegraph and telephone) or that were intended as a person to person communication.

What is Boot disk?

A boot disk is a removable digital data storage medium from which a computer can load and run (boot) an operating system or utility program. The computer must have a built-in program that will load and execute a program from a boot disk meeting certain standards.

What is Boot?

In computing, booting (or booting up) is the initialization of a computerized system. The system can be a computer or a computer appliance. The booting process can be "hard" after electrical power to the CPU is switched from off to on (in order to diagnose particular hardware errors), or "soft", when those power-on self-tests (POST) can be avoided.

What is Bookmark?

In the context of the World Wide Web, a bookmark is a Uniform Resource Identifier (URI) that is stored for later retrieval in any of various storage formats. All modem web browsers include bookmark features. Bookmarks are called favorites or Internet shortcuts in Internet Explorer, and by virtue of that browser's large market share, these browser wars. Bookmarks are normally accessed through a menu in the user's web browser, and folders are commonly used for organization.

What is Bluetooth?

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

What is Blogger?

Blogger is a blog-publishing service that allows multi-user blogs with time-stamped entries. It was developed by Pyra Labs, which was bought by Google in 2003. Generally, the blogs are hosted by Google at a subdomain of blogspot.com. A user can have up to 100 blogs per account.

What is Blog?

A blog is a discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order (the most recent post appears first). Until 2009 blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject. More recently "multi-author blogs" (MABs) have developed, with posts written by large numbers of authors and professionally edited.

What is BIOS?

The BIOS (Basic Input / Output System) is a type of firmware used during the booting process (power-on startup) on IBM PC compatible computers. The BIOS firmware is built into PCs, and it is the first software they run when powered on.

What is Binary?

In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system, or base-2 numeral system, which represents numeric values using two different symbols; typically 0 (Zero) and 1 (one). The base-2 system is a positional notation with a radix of 2.

What is Bar chart?

A bar chart or bar graph is a chart with rectangular bars with lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column bar chart.

What is Brandwidth?

In computing, bandwidth is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second. Variously, bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth.

What is AVAST?

Avast is a brand of antivirus software developed by AVAST Software s.r.o for Microsoft Windows, Mac OSX, Android, and Linux users. The software products have a user interface available in 45 languages.

What is Audio Card?

An audio sound card (also known as a sound card) is an internal computer expansion card that president between input and output of audio signals to and from a computer on the control of computer programs.

What is Audio?

An audio signal is a representation of sound typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20000 Hz (the limits of human hearing). Audio signals may be synthesized directly or may originate at a transducer such as a microphone musical instrument pickup, phonograph cartridge, or tape head. Loudspeakers or headphones convert an electrical audio signal into sound.

What is AVI?

Audio Video interleaved (AVI) is a multimedia container format introduced by Microsoft in November 1992 as part of its video for Windows software. AVI files can contain both audio and video data in a file container that allows synchronous audio with video playback.
