COURSE PLAN

COMPUTER NETWORKS-1


Course Objectives

            Computer Networking-I explain fundamentals of this subject. It provides logical method of explaining various complicated concepts and stepwise methods to explain the important topics. Each unit of syllabus is well supported with necessary illustrations, practical examples. All care has been taken to make students comfortable in understanding the basic concepts of the subject.
            Computer Network-I not only covers the entire scope of the subject but explains the philosophy of the subject. This makes the understanding of this subject clearer and makes it more interesting. Computer Networking-I will be very useful not only to the students but also to the subject teachers.
            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. But before we ask how quickly we can get hooked up, we need to know how networks operate, what types of technologies are available, and which design best fills which set of needs. So the subject gives the full idea about it.

What is System ¨ A system is a set of components which are related by some form of interaction and which act together to achieve some objective or purpose n Components are the individual parts or elements that collectively make up the system n Relationships are the cause-effect dependencies between components n Objective is the desired state or outcome which the system is attempting to achieve What is Simulation ¨ A simulation of a system is the operation of a model of the system, as an imitation of the real system ¨ A tool to evaluate the performance of a system, existing or proposed, under different configurations of interest and over a long period of time n e.g. a simulation of an industrial process to learn about its behavior under different operating conditions in order to improve the process n Reasons for Simulation ¨ Experiments on real systems are too expensive, too dangerous, or the system to be investigated does not yet exist n e.g. Investigating...

UNIT 4 Editors and Debugging Systems This Chapter gives you…  Text editors  Interactive Debugging Systems 4.0 Introduction An Interactive text editor has become an important part of almost any computing environment. Text editor acts as a primary interface to the computer for all type of “knowledge workers” as they compose, organize, study, and manipulate computer-based information. An interactive debugging system provides programmers with facilities that aid in testing and debugging of programs. Many such systems are available during these days. Our discussion is broad in scope, giving the overview of interactive debugging systems – not specific to any particular existing system. 4.1 Text Editors An Interactive text editor has become an important part of almost any computing environment. Text editor acts as a primary interface to the computer for all type of “knowledge workers” as they compose, organize, study, and manipulate computer-based information. A text edi...

Notes OF Information System

ntroduction 1.1 MANAGEMENT INFORMATION SYSTEM ( MIS) CONCEPT The concept of the MIS has evolved over a period of time comprising many dif erent facets of the organizational function. MIS is a neces ity of al the organizations. The init al concept of MIS was to proces data from the organization and present it in the for of reports at regular intervals. The system was largely capable of handling the data from col ection to proces ing. It was more impersonal, requiring each individual to pick and cho se the proces ed data and use it for his requirements. This concept was further modified when a distinction was made betwe n data and information. The information is a product of an analysis of data. This concept is similar to a raw material and the finished product. What are ne ded are information and not a mas of data. However, the data can be analyzed in a number of ways, producing dif erent shades and specifications of the information as a product. It was, therefore, demanded ...
