Even though the title of the text is "An Introduction to Networking", the author seems to assume that the student or reader knows a lot about the subject matter and terminology.
Odom, W. This fully updated edition presents complete reviews and a more challenging and realistic exam preparation experience. Senior instructor and best-selling author Wendell Odom shares preparation hints and test-taking tips, helping you identify areas of weakness and improve both your conceptual knowledge and hands-on skills. The material is presented in a concise manner, focused on increasing your understanding of exam topics and preparing you for the numerous challenges the exams present. Chapter-ending Exam Preparation Tasks sections help you drill on key concepts you must know thoroughly and help increase your speed in answering questions, a difficult hurdle many exam candidates face on the new exams.
A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design. Network protocols are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications. Neither local area networks LAN nor wide area networks WAN could function the way they do today without the use of network protocols. Network protocols take large-scale processes and break them down into small, specific tasks or functions. This occurs at every level of the network, and each function must cooperate at each level to complete the larger task at hand.

Computer network , two or more computers that are connected with one another for the purpose of communicating data electronically. Besides physically connecting computer and communication devices, a network system serves the important function of establishing a cohesive architecture that allows a variety of equipment types to transfer information in a near-seamless fashion. LANs connect computers and peripheral devices in a limited physical area, such as a business office, laboratory, or college campus, by means of links wires, Ethernet cables, fibre optics , Wi-Fi that transmit data rapidly. A typical LAN consists of two or more personal computers , printers, and high-capacity disk-storage devices called file servers, which enable each computer on the network to access a common set of files. LAN operating system software , which interprets input and instructs networked devices, allows users to communicate with each other; share the printers and storage equipment; and simultaneously access centrally located processors, data, or programs instruction sets. WANs connect computers and smaller networks to larger networks over greater geographic areas, including different continents. They may link the computers by means of cables, optical fibres , or satellites , but their users commonly access the networks via a modem a device that allows computers to communicate over telephone lines.

A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network may include personal computers , servers , networking hardware , or other specialised or general-purpose hosts.
Internet layer. Fourth Edition TMH, PDF download. In this paper, we describe the design, specification, and usage of Cefore as well as Cefore-Emu and Cefore-Sim. There are several streams and area of specializations under computer network in which students shall have their own choices for their future career.
Его массивная фигура буквально нависла над ней, запах одеколона ударил в ноздри. - Я сказала. - Она смотрела ему прямо в .
Что. - Я вызываю агентов безопасности. - Нет, коммандер! - вскрикнула Сьюзан. - Нет. Хейл сжал ее горло. - Если вы вызовете службу безопасности, она умрет.
