A Token Bus Network is a network protocol used to transmit data. In a Token Bus Network, a virtual ring is formed between nodes/stations and token is transferred from one station to another in a sequential manner. Each node in a Token Bus Network knows the address of its successor and predecessor and can transmit data if it has the token. A Token Ring Network is similar to a Token Bus Network but it works around the physical ring instead of a virtual ring. A token is passed from one node to another in a sequential manner and each node ... Read More
Steganography, or cover writing, is a method where a secret method is converted into fake looking message. This technique helps to keep a message secret. It is pretty difficult to use and understand. The structure of data remains unaltered in Steganography. It is used in text, audio, video or images. Cryptography, or secret writing, is a method where a secret method is converted in cipher text and sent to other person who then decrypt the cipher text into plain text. Cryptography can be classified as Symmetric key cryptography or Asymmetric key cryptography. Read through this article to find out more ... Read More

This tutorial will discuss how to write a swift program to calculate simple interest. Simple interest is the most commonly used method to find the interest on the money for a given time period. In this method, the interest is always applied to the original principal amount with same the interest rate for every time period. It is calculated by multiplying the interest rate by the principal amount and the time. Formula Following is the formula of simple interest − S.I = Principal Amount(P) x Time(T) x Rate(R)/100 Where Principal(P) − Principal amount represents the amount that is initially invested. ...

If the browser does not support the Fullscreen API, you can still provide a fullscreen experience to your users by using another method, such as opening a new browser window. Assuming the browser does support the Fullscreen ... Read More
You can choose between creating an EXE or a DLL when writing Dot NET code. Both of these include executable code, however, DLL and EXE operate differently from one another. The EXE will create its own thread and reserve resources for it if you run it. A DLL file, on the other hand, is an in-process server, so you cannot run a DLL file on its own. A DLL's code is used by a running application by loading and calling the DLL. The primary objective of a DLL is to facilitate the process of compartmentalizing a computer program. ... Read More
Both the TRUNCATE statement and the DELETE statement are included in the category of SQL queries for deleting the data stored in a table. They carry out deletion operations on records or rows of a table that are no longer needed. A condition is applied before each entry in the table that is being deleted when using the DELETE command. To put it another way, it is possible to delete one or more rows all at once. However, with the TRUNCATE command, each row is removed from the table simultaneously. When we delete something using the DELETE query, a log ... Read More
