Define Networking?



What is Networking?


A network is a collection of computers, servers, and components. These allows for the easy flow of data and use of resources between one another. Networking is the practice of communicating two or more computers or devices for the purpose of sharing data. Networking helps the communication among multiple computers easily. With the help of computer networking the user access may be restricted when necessary. With the help of creating a network, devices like printers and scanners, files and data that are stored in the system can be shared.
In networking the communication language used by computer devices is called the protocol. Network implement multiple protocols for to support specific application. 



Which type of functions are performed by Data Transmission Software or Protocols?



Which type of functions are performed by Data Transmission Software or Protocol?

We know computers send and receive data across communication links. We use data communication software for it. The procedure of data transmission in the form of software is known as Protocol. The data transmission software or protocols perform the following functions for transmission of data.

  • Data Sequencing:- We break a large message into small and fixed size of packets for error free data transmission. 
  • Data Routing:- In data routing we search the most efficient route for sending data between source and destination.
  • Flow Control:- It makes the flow between fast sender and slow receiver for regulating the process of sending data. 
  • Error Control:- It is the main function for communication software for error detecting and recovering it.

What is Data Communication ?


We know communication is the process of sharing information from one to another. For example the conversation between two people. Data Communication is the exchange of  data between between two devices via some form of transmission media such as wire. It is the transmission of digital data and has the objective to send data at highest speed but lowest cost. Electronic communications like emails and instant messages as well as telephone calls are examples of data communications. The effectiveness of a data communication system depends on the following charcteristics:-



  • Delivery
  • Accuracy
  • Timeliness.



Basic Terms Used In Data Communication:-


  • Data:- Collection of facts(Raw Forms)
  • Signals:- Encoding of data.
  • Signaling:- Propagation of signals via communication medium.
  • Transmission:- Communication of data by processing of signals.




What do you mean By CN?


What do you mean By CN?

CN stands for Computer Network. It is a collection of computers and devices that shares the information across wired or wireless technology. Computer networking needs at least two computers, hardware to connect them and a protocol. Computer networks allow people and machines to communicate, using a number of services. Computer network provide us facility of communication. We can easily communicate to people via emails, chat, telephone and voice and video conferencing. We can share data, files and and other important information easily. We can also use resources provided by devices on the network such as printer.
