The purpose of a computer communications network is to allow
moving information from one point to another inside the network. The
information could be stored on a device, such as a personal computer in the
network, it could be generated live outside the network, such as speech, or
could be generated by a process on another piece of information, such as
automatic sales transactions at the end of a business day. The device does not necessarily have to be a computer; it could be a hard disk, a camera or even a printer on the network. Due to a large variety of information to be moved, and due to the fact that each type of information has its own conditions for intelligibility, the computer network has evolved into a highly complex system. Specialized knowledge from many areas of science and engineering goes into the design of networks. It is practically impossible for a single area of science or engineering to be entirely responsible for the design of all the components. Therefore, a study of computer networks branches into many areas as we go up from fundamentals to the advanced levels. Advancements in communication of speech have long been matured
in the form of public switched telephone network (PSTN). However, design
of store-and-forward type of networks, such as the internet, is far from
matured - perhaps due to proliferation of the ways in which such networks are
used. The integration of the two types of networks is the culmination of
telecommunications technology. It is not futuristic to imagine
telecommunications networks meeting the needs of live traffic (e.g., phone
calls) as well as store-and-forward data (e.g., email) traffic according to the
desired quality of service.
In this chapter, we look at a computer network as a whole, from both
an application point of view and a design point of view. In fact, the design and
application influence each other so much that a study of the fundamentals is
practically impossible by leaving either one out
What else can I help you with?
What revision most effectively correct the faulty coordination in this sentence the internet has changed communications and it allows computer networks to interconnect?
The Internet has changed communications by allowing computer networks to interconnect.
What is DQDB in computer networks?
In telecommunication, a distributed-queue dual-bus network (DQDB) is a distributed multi-access network that (a) supports integrated communications using a dual bus and distributed queuing, (b) provides access to local or metropolitan area networks, and (c) supports connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications. IEEE 802.6 is an example of a network providing DQDB access methods.
What is the meaning of network of networks?
This is usually used to describe the Internet. A few computers connected together is a computer network. A few computer networks connected together is a network of networks.

What are the types of information and communications technology?
Information and communications technology (ICT) is constantly changing. ICT combines telephones, computer networks, and audio visual networks to give the consumer a better experience when making phone calls, using the internet, or watching television.
How has the decreasing cost of computer hardware contributed to the merging of computers and communications?
Computers and communications have both dramatically declined in costs, making it practical to digitize networks on a large scale.
