Some books are like wine, the older the better. That is the case with the book "Data Communications, Computer Networks and Open Systems". Nowdays, some issues are taken for granted or assumed that these issues were well explaned in the books in the pastCited by: Now in its third edition, Understanding Data Comunications, provides a comprehensive introduction to the field of data communications for both students and professionals.

Assuming no prior knowledge of the field, it presents an overview of the role of communications, their importance, and the fundamental concepts of using the ISO's 7-layer 4/4(1). Communication Systems by Dr Cong Ling. This note covers the following topics: Communication Channel, Noise in Communications, Growth of Mobile Communications, Wi-Fi, Satellite or Space Communication, Effects of noise on analog communications, Noise performance of DSB, SSB, FM and AM, Digital communications, Digital modulation, Noncoherent demodulation.

Forouzan has 37 books on Goodreads with ratings. Behrouz A. Forouzan’s most popular book is Data Communications and Networking (McGraw-Hi. 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 4/5(5). I used to like "parts" of different books. There was a neat book by Roddy and Coolen that made early studies on Modulation theory very easy.

Mischa Schwartz's Information Transmission, Modulation and Noise was a favourite, as was of course Simon H. Data Communication Overview. Data communication happens whenever at least two computers transmit information to each other.

In order for this communication to work, a system must be in place that transfers the information from point A to point B. ALTTC/NP/KKD/Data Communication 34 Data Units • Protocol Control Information (PCI) – (N)-PCI is the protocol control information exchanged between the (N)-entities to coordinate their functions • Service Data Units (SDU) – (N)-SDU is the data unit transferred between the ends of a (N)-connection whose identity is preserved during the File Size: KB.

Data communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, and vice versa. It enables the movement of electronic or digital data between two or more nodes, regardless of geographical location, technological medium or data contents.

Introduction []. This book will eventually cover a large number of topics in the field of electrical communications.

The reader will also require a knowledge of Time and Frequency Domain representations, which is covered in-depth in the Signals and Systems book. This book will, by necessity, touch on a number of different areas of study, and as such is more than just a text.

The Little Data Book on Information and Communication Technology v Preface Since the late s access to information and communication technolo-gies (ICTs) has seen tremendous growth—driven primarily by the wireless technologies and liberalization of telecommunications markets.

Mobile com -File Size: 7MB. 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 1/5(1).

The topics covered in the attached e-books are: Unit I: INTRODUCTION TO DATA COMMUNICATIONS AND NETWORKING: Standards Organizations for Data Communications, Layered Network Architecture, Open Systems Interconnection, Data Communications Circuits, Serial and parallel Data Transmission, Data communications Circuit.

In telecommunication, a communications system or communication system is a collection of individual communications networks, transmission systems, relay stations, tributary stations, and data terminal equipment usually capable of interconnection and interoperation to form an integrated whole.


The components of a communications system serve a common purpose, are. Data Communication System “Our technical know-how has been accumulated over more than two decades.” The world has now truly become dependent on wireless data communication systems, and several new technologies have redefined data communication.

What hasn’t changed, however, is that all wireless networks, LAN facilities, broadband and GPS systems are. RS is a simple protocol that is implemented on a twisted wire bus.

The system allows a couple of dozen devices to be networked as far as 1 km, with a data rate of up to 1 Mbps. Ethernet is an example of a baseband system implemented on a bus. Further reading. Serial Programming/Forming Data Packets.
