Most linguistic studies of human-computer communication have focused on the issues of syntax and discourse structure. However, another interesting and important area is the lexical semantics of c o m m a n d languages. The names that users and system designers give the objects and actions of a computer system can greatly affect its usability, a n d the lexical issues involved are as complicated as those in natural languages.

This book attempts to provide a unified overview of the broad field of data and computer communications.
The organization of the book reflects an attempt to break this massive subject
into comprehensible parts and to build, piece by piece, a survey of the state of the art.The book
emphasizes basic principles and topics of fundamental importance concerning the technology
and architecture of this field and provides a detailed discussion of leading-edge topics.
The following basic themes serve to unify the discussion:...
After you read chapter 8 you should be able to: Discuss the purpose of the components required for successful communications; describe these uses of computer communications: wireless messaging services, wireless Internet access points, cybercafés, global positioning systems, collaboration, groupware, voice mail, and Web services; differentiate among types of networks: LANs, MANs, and WANs;...
Discovering Computers - Chapter 9: Communications and Networks includes Communications, Uses of Computer Communications, Networks, Network Communications Standards, Communications Software, Communications Over the Telephone Network.
The TCP/IP protocol suite has become the de facto standard for computer communications in today's networked world. The ubiquitous implementation of a specific networking standard has led to an incredible dependence on the applications enabled by it. Today, we use the TCP/IP protocols and the Internet not only for entertainment and information, but to conduct our business by performing transactions, buying and selling products, and delivering services to customers.
Built upon a foundation of Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL) and Universal Description Discovery and Integration (UDDI) technologies, Web services have become a widely accepted industry standard in the last few years [1, 2]. Because of their platform independence, universal compatibility, and network accessibility, Web services will be at the heart of the next generation of distributed systems. As more vendors offer SOAP tools and services, the advantages of using SOAP and Web services as an integration point will become even more pronounced.
All email communications on the internet are possible by two protocols:
1) Simple Mail Transfer Protocol (SMTP port-25)
2) Post Office Protocol (POP port-110)
E-Mail hacking consists of various techniques as discussed below.The most effective and easiest way to trace an email is to analyze it's email headers. This can be done by just viewing the full header of received email.
Information communications technology (ICT) has been found to be one of the most potent tools for promot-
ing equity and access to education, and a great resource in bridging the gap of the digital divide. ICT affects
almost all of our everyday activities, be it business, defense, or space exploration. Being informed of the latest
information has become essential for survival. Educational enterprises also beneft from the advantages and
technological learning tools offered by ICT. ICT is indispensable for creating effective distance education learn-
For some years, commentators have been predicting the 'convergence' of the Internet and
mobile industries. But what does convergence mean? Is it just about mobile phones providing
Internet access? Will the coming together of two huge industries actually be much more about
collision than convergence? In truth, there are lots of possibilities about what convergence
might mean, such as:
• Internet providers also supply mobile phones - or vice versa, of course.
• The user's mobile phone is replaced with a palmtop computer.
• The mobile Internet leads to a whole range of new applications.
The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The
three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process.
A comprehensive yet comprehensible and witty guide to the latest advances in computer network security protocols. The author team includes Charlie Kaufman, currently chief security architect for Lotus Notes, and formerly Network Security Architect at Digital Equipment Corporation;
A web-based Knowledge Base System is an online Knowledge resource on the net. Knowledge Base System creates a huge archive of information on a website that help people gain knowledge. Knowledge Base System also is a communication tool that helps people share knowledge quickly and easily.
The purpose of a computer communications network is to allow
moving information from one point to another inside the network. The
information could be stored on a device, such as a personal computer in the
network, it could be generated live outside the network, such as speech, or
could be generated by a process on another piece of information, such as
automatic sales transactions at the end of a business day
Describe the structure of a network, including the devices and media that are necessary for successful communications. Explain the function of protocols in network communications. Explain the advantages of using a layered model to describe network functionality. Describe the role of each layer in two recognized network models: The TCP/IP model and the OSI model. Describe the importance of addressing and naming schemes in network communications.
My undivided gratitude to Allah S.W.T that has given me blessings and strength to complete this project entitled “Modeling Intersatellite Optical Wireless Communication System” successfully.
I wish to express my sincere appreciation to my Supervisor, Dr. Sevia M. Idrus, for her constant guidance, counsels, and putting much effort upon the completion of this project. I also would like to thank my lecturers in the Faculty of Electrical Engineering who have taught me throughout the semesters.
Computer organization and architecture Ninth edition - William Stallings is the good book for undergraduates and professionals in computer science, computer engineering, and electrical engineering courses, learn the fundamentals of processor and computer design from the newest edition of this award-winning text.
Data communications and networking are changing the way we do business and the way
we live. Business decisions have to be made ever more quickly, and the decision makers
require immediate access to accurate information. Why wait a week for that report
from Germany to arrive by mail when it could appear almost instantaneously through
computer networks? Businesses today rely on computer networks and internetworks.
