Using an easy-to-follow, layered structure, this unique text begins with a gentle introduction for those new to the subject, before moving on to explain key information-theoretic principles and ...

In Chapter 4 we focused mostly on media and the physical layer (layer 1 of the OSI model), and did not include any discussion about specific network components. Similarly, Chapter 5, which examined ...

it affords an additional protection layer. We can also use the fundamental physical characteristics of the wireless channel -such as noise and channel variations- to provide secure communications.

Typically used in test labs and controlled by software, the physical layer switch resembles the old telephone switchboard, which cross-connected an input telephone line to an output line.

is the process of a user confirming that they are who they say they are on a computer system. In a network, this is often done through inputting a username and password. For networks that require ...

A solid capability for abstract thinking is also essential for networking, like most other computer science fields. Networking typically involves a layered architecture where each layer is an ...

Common topologies for computer networks include bus, ring, star, tree, and mesh. Hybrid topologies are also used. In wireless networks, devices communicate via radio waves and do not require physical ...

When it comes to tasks other than number crunching, the human brain possesses many advantages over a digital computer ... Such a network is called a multi-layer perceptron or a feed-forward ...

Networks allow people to access the same information from any computer on the network. Some computers use a cable to connect to a network. This cable is called an ethernet cable. Other computers ...
