Introduction The source code consists of the programming statements that are created by a programmer with a text editor or a visual programming tool and then saved in a file. For example, a programmer using the C language types in a desired sequence of C language statements using a text editor and then saves them as a named … Read more

What is a Primary Key? A primary key is a special relational database table column (or combination of columns) designated to uniquely identify each table record. It is a unique identifier, such as a driver license number, telephone number (including area code), or vehicle identification number (VIN). A relational database must always have one and … Read more

HTML <Div> Tag The div tag is known as Division tag. The div tag is used in HTML to make divisions of content in the web page like (text, images, header, footer, navigation bar, etc). In other words, the HTML <div> tag is used to group the large section of HTML elements together. Div tag has both open(<div>) … Read more

RSA Algorithm RSA is a type of cryptosystem algorithm. RSA algorithm works on the basis of the mathematical fact that it is not easy to factor the product of two prime numbers. RSA algorithm came into existence in 1977. RSA was developed by Leonard Aldeman, Aldi Shamir and Ron Rivest. The process of key generation … Read more

What Is Lossy Compression? Lossy compression also referred to as irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. In other words, it is a method of data compression in which the size of file is reduced by eliminating data in the file. … Read more

What Is a Servlet? A servlet is a Java programming language class that is used to extend the capabilities of servers that host applications accessed by means of a request-response programming model. Although servlets can respond to any type of request, they are commonly used to extend the applications hosted by web servers. For such applications, Java … Read more

What is Current? In electric circuits, current is the flow of electric charge. It’s really electrons (charged particles) that move around in circuits. Electric current are the electrons or negatively charged particles that move around in circuits. So when current flows in some direction in a circuit, the actual physical effect is electrons flowing in the opposite … Read more

There are two types of circuit namely combinational circuit ( no memory elements to store past or future values which may affect the output ,only present input changes the output ) and sequential circuit ( memory element like flip-flop are involves which store data and changes the output ). Latches and flip-flops are the basic … Read more

What is a Desktop? A desktop computer is a personal computer designed for regular use at a single location on or near a desk due to its size and power requirements. The most common configuration has a case that houses the power supply, motherboard (a printed circuit board with a microprocessor as the central processing unit, memory, bus, certain peripherals and other electronic components), disk storage (usually one or more hard disk drives, solid state drives, optical disc drives, and … Read more

What Is Pushdown Automata? A pushdown Automata is essentially a finite automaton with an auxiliary data structure (extra memory) known as a stack, which helps Pushdown automata to recognize Context Free Languages. Pushdown automata are used in theories about what can be computed by machines. They are more capable than finite-state machines but less capable … Read more
