Ans: An extensive system used for declaring variables or functions of different types, integer, float, character, string, etc are data types used in C. What is a compiler? Ans: A type of translator that converts high-level programming language to machine language. In other words, it converts the source program into an object program. What is an Interpreter? Ans: It converts high-level language into machine language just like a compiler. However, the interpreter executes the line and shows the immediate result. What is Structured programming? Ans: Edgar D Costa first gave the idea

What is encryption?

What is encryption? Before sending the data from one place to another, the method of changing its main format to another format is called encryption.

What is Data Warehouse?

What is Data Warehouse? The data warehouse is a logical collection of data and information that is collected from various operational databases. It is used to create support for business analysis, business intelligence, and the decision-making process. 

What is Data Mining?

What is Data Mining? Data Mining reveals hidden special features present in data obtained from data warehouses. Data mining is the process of sorting through large data sets to identify patterns and establish relationships to solve problems through data analysis.

What is DBMS?

What is Database?

What is Database? A database is a collection of information that is organized so that it can be easily accessed, managed, and updated. Data is organized into rows, columns, and tables, and index to make it easier to find relevant information.

Concept of Global Village

Concept of Global Village Before starting to learn about the global village, it is necessary to learn about information and technology as it is considered as the spine of the global village. Technology  This current era is called the era of information technology. Again contribution of technology can be seen in every part of this era. Today's human civilization is mainly the history of technological development.  Technology is the practical knowledge of the combined achievement of science and engineering. On the basis of human society, the definition of technology can be said as "Technology is some practical technique which man can use for his circumstantial development." Achieve knowledge about any machine and natural element and the power of using them efficiently is called technology. Every day we are using various technologies for making our life more comfortable. Information Technology The technology that collects information, integrates, validates, preserves, pr

What is numeric keypad?

Numeric Keypad A numeric keypad is used to enter numbers only (although some have a function key to allow input of alphabetic characters).    Numeric Keypad Uses Numeric keypads are used in automatic teller machines (ATMs), where customers can key in their personal identification number (PIN), an amount of money, etc. Telephones have numeric keypads to allow phone numbers, etc. to be keyed in. Electronic point of sale (EPOS) terminals have numeric keypads in case the barcode reader fails to read the barcode and the number has to be keyed in manually by the operator. Chip and PIN devices have numeric keypads for entry of PIN, amount of money, etc. They are used to enable fast entry of numeric data into a spreadsheet. Advantages Numeric keypads are faster than standard keyboards for entry of numeric data. Since many are small devices (e.g. mobile phones), they are very easy to carry around. Disadvantages They can be difficult to use, due to very small keys. It is difficult to use them fo

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.
