Introduction to Data Communications Author, educator, and researcher Andrew S. Windows NT networking for dummies. These books deal with computer networking: the discipline concerned with communication between computer systems or devices.
A computer network is a digital telecommunications network which allows nodes to share resources. Aside from this, they will be dependent on the main file server, which means that, if it breaks down, the system would become useless, making users idle. These links connecting the devices are called Communication channels. Computer Networks is the ideal introduction to today's and tomorrow's networks.

This is the first book that explains how computer networks work inside, from the hardware technology up to and including the most popular Internet application protocols. In the end Computer network are mainly divided into Local Area Network, Metropolitan area network, wide area network, wireless networks, Internetworks.
Computer Networks Book by Andrew S. All the computers can be interconnected using a network, and just one modem and printer can efficiently provide the services to all twelve users. To establish a computer network one needs to be equipped with the basic guidelines that help to lay down complex networks.
Computer network is a telecommunication channel using which we can share data with other coomputers or devices, connected to the same network.
The three parts of the book - bits, signals, and packets - cover three corresponding layers of abstraction. If users must take turns, it is a timeshared connection.
Physical Topology The term physical topology refers to the way in which a network is laid out physically. Two or more devices connect to a link; two or more links form a topology. There are four basic topologies possible: mesh, star, bus, and ring. Mesh Topology In a mesh topology, every device has a dedicated point-to-point link to every other device.
The term dedicated means that the link carries traffic only between the two devices it connects. First, the use of dedicated links guarantees that each connection can carry its own data load, thus eliminating the traffic problems that can occur when links must be shared by multiple devices.
Second, a mesh topology is robust. If one link becomes unusable, it does not incapacitate the entire system. When every message travels along a dedicated line, only the intended recipient sees it. Physical boundaries prevent other users from gaining access to messages. Finally, point-to-point links make fault identification and fault isolation easy.
Traffic can be routed to avoid links with suspected problems.
This facility enables the network manager to discover the precise location of the fault and aids in finding its cause and solution. First, because every device must be connected to every other device, installation and reconnection are difficult.
Second, the sheer bulk of the wiring can be greater than the available space in walls, ceilings, or floors can accommodate. For these reasons a mesh topology is usually implemented in a limited fashion, for example, as a backbone connecting the main computers of a hybrid network that can include several other topologies. Star Topology In a star topology, each device has a dedicated point-to-point link only to a central controller, usually called a hub.
The devices are not directly linked to one another. Unlike a mesh topology, a star topology does not allow direct traffic between devices.
The controller acts as an exchange: If one device wants to send data to another, it sends the data to the controller, which then relays the data to the other connected device. This factor also makes it easy to install and reconfigure. Far less cabling needs to be housed, and additions, moves, and deletions involve only one connection: between that device and the hub.
If one link fails, only that link is affected. All other links remain active. This factor also lends itself to easy fault identification and fault isolation. As long as the hub is working, it can be used to monitor link problems and bypass defective links.
If the hub goes down, the whole system is dead. Although a star requires far less cable than a mesh, each node must be linked to a central hub. For this reason, often more cabling is required in a star than in some other topologies such as ring or bus. High-speed LANs often use a star topology with a central hub. In Tree topology, the central controller can be active and passive. Bus Topology A bus topology is multipoint connection.
One long cable acts as a backbone to link all the devices in a network. The bus cable is end with cable ends or Terminators each end.
A drop line is a connection running between the device and the main cable. A tap or T-Connector is a connector that either splices into the main cable or punctures the sheathing of a cable to create a contact with the metallic core. Therefore, it becomes weaker and weaker as it travels farther and farther.
For this reason there is a limit on the number of taps a bus can support and on the distance between those taps. Backbone cable can be laid along the most efficient path, then connected to the nodes by drop lines of various lengths. In this way, a bus uses less cabling than mesh or star topologies. In a star, for example, four network devices in the same room require four lengths of cable reaching all the way to the hub. Signal reflection at the taps can cause degradation in quality.
Data Communications and Networking (McGraw-Hill Forouzan Networking)
This degradation can be controlled by limiting the number and spacing of devices connected to a given length of cable. Adding new devices may therefore require modification or replacement of the backbone. Data Communications and Networking by Behrouz A. Forouzan-4th Edition 42 Physical Topology In addition, a fault or break in the bus cable stops all transmission, even between devices on the same side of the problem.
The damaged area reflects signals back in the direction of origin, creating noise in both directions. Bus topology was the one of the first topologies used in the design of early local area networks. Ethernet LANs can use a bus topology, but they are less popular now because of its disadvantages.
Ring Topology In a ring topology, each device has a dedicated point-to-point connection with only the two devices on either side of it. Forouzan-4th Edition 44 Physical Topology A signal is passed along the ring in one direction, from device to device, until it reaches its destination.
Each device in the ring incorporates a repeater. When a device receives a signal intended for another device, its repeater regenerates the bits and passes them along.
Each device is linked to only its immediate neighbors. To add or delete a device requires changing only two connections. In addition, fault isolation is simplified. Generally in a ring, a signal is circulating at all times. If one device does not receive a signal within a specified period, it can issue an alarm. The alarm alerts the network operator to the problem and its location.
Re: Computer Networks by Forouzan pdf download
In a simple ring, a break in the ring such as a disabled station can disable the entire network. This weakness can be solved by using a dual ring or a switch capable of closing off the break. Today, the need for higher-speed LANs has made this topology less popular. For example, we can have a main star topology with each branch connecting several stations in a bus topology 48 Categories of Networks Today when we speak of networks, we are generally referring to three primary categories: local-area networks, metropolitan-area networks and wide-area networks.
The category into which a network falls is determined by its size.
A LAN normally covers an area less than 2 miles. WAN can be worldwide. Networks of a size in between are normally referred to as metropolitan-area networks and span tens of miles.
Local Area Network A local area network LAN is usually privately owned and links the devices in a single office, building, or campus. Depending on the needs of an organization and the type of technology used, a LAN can be as simple as two PCs and a printer in someone's home office; or it can extend throughout a company and include audio and video peripherals.The term dedicated means that the link carries traffic only between the two devices it connects.
Communication When we communicate, we are exchange or sharing information. The entire capacity of the link is reserved for transmission between those two devices. This facility enables the network manager to discover the precise location of the fault and aids in finding its cause and solution. An Introduction to Computer Networks.
