The primary purpose of computer networks is to transfer data from a source machine to a destination machine. One of the elementary ways to transfer data between machines is to use removable storage media. The steps for the transfer are −Copy data from the source computer to the removable storage ...

Coaxial cables, commonly called coax, are copper cables with metal shielding designed to provide immunity against noise and greater bandwidth. Coax can transmit signals over larger distances at a higher speed as compared to twisted pair cables.Structure of Coaxial CablesCoax has a central core of stiff copper conductor for transmitting ...

The Deque class uses a doubly-linked list to implement its collection of elements.  The doubly-linked lists should have two nodes i.e. front and back nodes. This helps in adding elements on the front and back of the Deque.With the Deque class, you have the ability to add and remove elements ... Read More

Asynchronous programming in C# is an efficient approach towards activities blocked or access is delayed. If an activity is blocked like this in a synchronous process, then the complete application waits and it takes more time. The application stops responding. Using the asynchronous approach, the applications continue with other tasks ... Read More

Arrays of arrays in C# are known as Jagged Arrays. To declare jagged arrays, use the double [ ][ ].Let us now declare them −int [][] marks;Now, let us initialize it, wherein marks are arrays of 5 integers −int[][] marks = new int[][]{new int[]{ 90, 95 }, new int[]{ 89, ... Read More

A hierarchical model represents the data in a tree-like structure in which there is a single parent for each record. To maintain order there is a sort field which keeps sibling nodes into a recorded manner. These types of models are designed basically for the early mainframe database management systems, ...
