Data communication and Networking 2nd Edition
Computer networking refers to interconnected computing devices that can exchange data and share resources with each other.
These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies..
What are the 3 types of data communication?
Data communication between different devices are broadly categorised into 3 types: Simplex communication, Half- duplex communication, and Full-duplex communication.
It is a one way or unidirectional communication between two devices in which one device is sender and other one is receiver..
What is LAN WAN VPN?
Local Area Network (LAN) Wireless Local Area Network (WLAN) Wide Area Network (WAN) Virtual Private Network (VPN).
What is this computer network?
A computer network is a set of computers sharing resources located on or provided by network nodes.
Computers use common communication protocols over digital interconnections to communicate with each other..
Who creates computer networks?
Computer network architects design and implement data communication networks, including local area networks (LANs), wide area networks (WANs), and intranets.
These networks range from small connections between two offices to virtual capabilities such as a cloud infrastructure that serves multiple customers..
Why are computer networks important to an organization?
Benefits of computer networking
Not only does it allow staff to share information effortlessly, increasing productivity and efficiency, other benefits include cost-effectiveness, storage efficiency, flexibility, and data security..
Why computer network become so popular nowadays?
There are many reasons why computer networks are used in modern society.
Some of the key reasons include: Resource sharing: Networks enable multiple users to share resources such as printers, data storage devices, and other hardware and software resources..
The list of advantages of computer networks are:
Enhancement of Communication and Information Availability. Convenient Sharing of Resources. Easy File/Data Sharing. Highly Flexible. Affordable. Increases Cost Efficiency. Networking Boosts Storage Capacity.- Computer networks are formed by using nodes and connections (links) that enable teams to communicate with each other.
Each node uses a network interface card that defines how it interacts with the network.
Each network card has its own numeric address. - Local area network (LAN)
A LAN is an interconnected system limited in size and geography.
It typically connects computers and devices within a single office or building.
It is used by small companies or as a test network for small-scale prototyping.
