Computer Communications and Networks


Book Description

Computer communications is one of the most rapidly developing technologies and it is a subject with which everyone in the computer systems profession should be familiar. Computer communications and networks is an introduction to communications technology and system design for practising and aspiring computer professionals. The subject is described from the computer system designer's point of view rather than from the communications engineer's viewpoint. The presentation is suitable for introductory reading as well as for reference. The emphasis is on practical, rather than theoretical, aspects and on technology which will become more important in the future. The majority of the subject matter applies to civil and military communications but some aspects which are unique to military applications have been included where considered signifi cant. Computer communications is a rapidly changing and highly complex subject. Sufficient practical knowledge of the subject is not usually gained at university or college but is generally developed over a period of several years by trial and error, attending courses, reading reference books and journals; this book attempts to simplify and speed up the process by bringing together a body of information which is otherwise distributed throughout many books and journals. The information is presented in a framework which makes a wider understanding of the subject possible. Basic knowledge of communications is assumed, a general famil iarity with computer systems is anticipated in later chapters, and, where relevant, theory is explained.







DATA COMMUNICATIONS AND COMPUTER NETWORKS


Book Description

Primarily intended as a text for undergraduate courses in Electronics and Communications Engineering, Computer Science, IT courses, and Computer Applications, this up-to-date and accessible text gives an indepth analysis of data communications and computer networks in an easy-to-read style. Though a new title, it is a completely revised and fully updated version of the author’s earlier book Data Communications. The rapid strides made during the last decade in the fields of data communication and networking, and the close link between these two subjects have prompted the author to add several chapters on computer networks in this text. The book gives a masterly analysis of topics ranging from the principles of data transmission to computer networking applications. It also provides standard protocols, thereby enabling to bridge the gap between theory and practice. What’s more, it correlates the network protocols to the concepts, which are explained with the help of numerous examples to facilitate students’ understanding of the subject. This well-organized text presents the latest developments in the field and details current topics of interest such as Multicasting, MPLS, IPv6, Gigabit Ethernets, IPSec, SSL, Auto-negotiation, Wireless LANs, Network security, Differentiated services, and ADSL. Besides students, the practicing professionals would find the book to be a valuable resource. The book, in its second edition introduces a full chapter on Quality of Service, highlighting the meaning, parameters and functions required for quality of service. This book is recommended in Kaziranga University, Nagaland, IIT Guwahati, Assam and West Bengal University of Technology (WBUT), West Bengal for B.Tech. Key Features • The book is self-contained and student friendly. • The sequential organization lends flexibility in designing courses on the subject. • Large number of examples, diagrams and tables illustrate the concepts discussed in the text. • Numerous exercises (with answers), a list of acronyms, and references to protocol standards.




Aeronautical Telecommunications Network


Book Description

The Aeronautical Telecommunications Network: Advances, Challenges, and Mod










Computer Security


Book Description

Computer Security, Second Edition aims to present different ideas and practices that promote the prevention of attacks on computer systems and data being compromised. The book is divided into five parts. Part I covers the important elements of computer security and case histories of computer-related crimes. Part II discusses the organizations and models for the protection of information. Part III talks about the physical security involved and access control involved in data protection. Part IV deals with the different measures employed to promote security in the communication between computers. Part V explains systems security, its access control, and integrity. The text is recommended for people involved in the promotion of computer security, especially programmers and IT practitioners, in institutions where computer-processed information is crucial and must be protected.




Consolidated Ada Reference Manual


Book Description

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical 1 Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. 2 In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 8652 was prepared by Joint Technical Committee ISO/IEC JTC 1, 3 Information Technology. This second edition cancels and replaces the first edition (ISO 8652:1987), of which it constitutes a 4 technical revision. Annexes A to J form an integral part of this International Standard. Annexes K to P are for information 5 only. xi 15 June 2001 Foreword ISO/IEC 8652:1995(E) with COR.1:2000 — Ada Reference Manual Introduction 1 This is the Ada Reference Manual.




Protocol Specification and Testing


Book Description

The increasing number of computer networks has aroused users' interest in many and various fields of applications, in how a computer network can be built, and in how it may be used. The fundamental rules of computer networks are the protocols. "A protocol is a set of rules that governs the operation of functional units to achieve communication" [STA-86}. The book follows a practical approach to protocol speci fication and testing, but at the same time it introduces clearly and precisely the relevant theoretical fundamentals. The principal objectives of this work are: to familiarize readers with communication protocols, to present the main, formal description techniques, to apply various formal description techniques to protocol specification and testing. It is considered that the readership will primarily consist of protocol developers, protocol users, and all who utilize protocol testers. Secondly the book is suggested for postgraduate courses or other university courses dealing with communication networks and data communication. A large part of the book provides a comprehensive overview for managers; some parts are of especial interest to postal organizations. The book consists of three parts: the first part introduces the OS! Reference Model, it provides an overview of the most frequently used protocols and explains the fundamentals of protocol testing. The second part familiarizes readers with the methods used for protocol 5pecification, generation, and testing. Finite-state machines, formal grammars, Petri nets and some speCification languages (SDL, ESTELLE, LOTOS) are discussed in a pragmatic style. The third part deals with applications.
