Data communication and networking topics
Computer networks extend interpersonal communications by electronic means with various technologies, such as email, instant messaging, online chat, voice and video telephone calls, and video conferencing.
A network allows sharing of network and computing resources..
How do computers send data via a network?
A.
Computers send information through the Internet by dividing the data to send into small chunks ("packets") and transmitting them to the other device.
All this happens without your doing anything - the web browser, e-mail program, etc. all take care of these low level details..
How does data communication network work?
Data communication networks transmit digital data from one computer to another computer using a variety of wired and wireless communication channels.
One such network, the Internet, is an immense global network of smaller interconnected networks linking millions of computers..
Important topics in networking
Computer networks connect nodes like computers, routers, and switches using cables, fiber optics, or wireless signals.
These connections allow devices in a network to communicate and share information and resources..
Types of computer network
Data communications and networking is a truly global area of study, both because the technology enables global communication, and because new technologies and applications often emerge from a variety of countries and spread rapidly around the world.
A Brief History of Communications in the U.S..
Types of computer network
Server.
What is an example of a computer network communication?
A simpler example is using collaboration software such as Google Drive to share documents with colleagues who work remotely.
Every time we connect via a video call, stream movies, share files, chat with instant messages, or just access something on the internet, a computer network is at work..
What is the data communication model of a computer network?
An architectural model developed by the International Standards Organization (ISO) is frequently used to describe the structure and function of data communications protocols.
This architectural model, called the Open Systems Interconnect (OSI) Reference Model, provides a common reference for discussing communications..
Why computer network is necessary in data communication?
Computer Networks Allow Resources to Be Shared
Networks connect multiple computers and devices so that resources can be shared.
Rather than providing a printer, copier, or fax machine for every worker, each team member can be connected to the same devices in an office, which saves companies money..
