Focused on fundamental concepts and practical applications, this book provides a strong foundation in the principles and terminology of computer networking and internet technology. This thoroughly revised second edition, incorporating some of the latest technical features in networking, is suitable for introductory one-semester courses for undergraduate students of computer science and engineering, electronics and telecommunication engineering, information technology, as well as students of computer applications (BCA and MCA). This text begins with an overview of computer networking and a discussion on data communication. Then it proceeds to explain how computer networks such as local area networks (LANs) and wide area networks (WANs) work, and how internetworking is implemented. Besides, the book provides a description of the Internet and TCP/IP protocol. With the prolific growth of networking, ‘network management and security’ has become an increa-singly important part of the academic curriculum. This topic has been ade-quately dealt with in a separate chapter. The practical aspects of networking, listing the essential requirements needed for actually setting up a computer network, are thoroughly explained in the final chapter of the book. WHAT IS NEW IN THE SECOND EDITION • Wireless LAN in Chapter 4 • API and Socket Programming and End-to-End Protocol in Chapter 7 • Remote Procedure Call (RPC) Protocol in Chapter 8 • Dynamic Host Configuration Protocol –Error reporting by ICMP –Virtual Private Network (VPN) in Chapter 9 –Network Address Translation (NAT) An appendix dealing with telephone networking, wireless networking, cellular networking and satellite and telemetry communication has been included to meet the requirements of the students.

Informatics in Medical Imaging provides a comprehensive survey of the field of medical imaging informatics. In addition to radiology, it also addresses other specialties such as pathology, cardiology, dermatology, and surgery, which have adopted the use of digital images. The book discusses basic imaging informatics protocols, picture archiving and communication systems, and the electronic medical record. It details key instrumentation and data mining technologies used in medical imaging informatics as well as practical operational issues, such as procurement, maintenance, teleradiology, and ethics. Highlights Introduces the basic ideas of imaging informatics, the terms used, and how data are represented and transmitted Emphasizes the fundamental communication paradigms: HL7, DICOM, and IHE Describes information systems that are typically used within imaging departments: orders and result systems, acquisition systems, reporting systems, archives, and information-display systems Outlines the principal components of modern computing, networks, and storage systems Covers the technology and principles of display and acquisition detectors, and rounds out with a discussion of other key computer technologies Discusses procurement and maintenance issues; ethics and its relationship to government initiatives like HIPAA; and constructs beyond radiology The technologies of medical imaging and radiation therapy are so complex and computer-driven that it is difficult for physicians and technologists responsible for their clinical use to know exactly what is happening at the point of care. Medical physicists are best equipped to understand the technologies and their applications, and these individuals are assuming greater responsibilities in the clinical arena to ensure that intended care is delivered in a safe and effective manner. Built on a foundation of classic and cutting-edge research, Informatics in Medical Imaging supports and updates medical physicists functioning at the intersection of radiology and radiation.

Introduction to Data Networks describes the different types of data networks, how they operate and the services they can provide.Data networks are telecommunications networks that are installed and operated for information exchange between data communication devices such as computers and voice gateways. Although data networks can transfer any type of digital media (voice, data or video), the type of network, services used and optional configurations can dramatically affect the performance of data services.This book provides a functional description of the key data network parts including hubs, routers, bridges and gateways. You will discover the differences between personal area networks (PANs), premises distribution networks (PDNs), local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs).The basic operation of Ethernet is provided along with how Ethernet has evolved and the different types of Ethernet systems that are available today. Discover how data networks are configured and managed using simple network management protocol (SNMP). Learn the basic operation of gateways and firewalls and how firewalls operate to protect networks from the unwanted transmission of information. The operation of different types of data systems and how they operate is explained including Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay, and the Internet. Find out how data networks can be configured to allow many users to share the same data network using virtual private networks. You will lean about the common types of data services such as CBR, ABR, UBR and their typical service costs. Some of the most important topics featured are:?Functional parts of data networks ?Descriptions of hubs, routers, bridges and gateways.?The differences between PAN, PDN, LAN, MAN, and WAN Networks?How Ethernet and other types of data networks operate?How packets are automatically routed in IP networks?How gateways and firewalls operate?Overviews of Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay and the Internet?Introduction to virtual networks (VPNs)?Data services including CBR, ABR and UBR
