IP Addressing


IP Addressing:
IP Address is of 32 bits. Eg : 192.168.2.25
No 2 system can have same IP as network conflict occurs.
Address space IPV4  is 232
Notations
1.       Binary notation – 0&1
2.       Dotted decimal notation -0-9
3.       Hexadecimal-0-15

Types of IP Addressing
1.       Class Full addressing: IP address space is divided/classified into 5 classes A,B,C,D and E.
Address space of class A-231
Address space of class B-230
Address space of class C-229
Address space of class D-228
Address space of class E-228





Problems in Class A and B
Host Id remains fixed & net id changes, 3 net id are there in class A and 2 net id  in class B and so it is difficult to change it again and again.
A & B-small organization
C- large organization
D -military, for multicast addressing
E-reserved for future use
Net ID- Network id
Host id-id given to the system
Class A, B and C are divided into net id and host id. These parts are of varying length depending on the class of the address. Host id means the name of the system is connected via networking.
Class C- LAN networking.

Simulation Practice Problems

1. There is only one telephone in a public booth of a metro station. Following table indicates the distribution of arrival time and duration of calls: Time Between arrivals (minutes) 4 5 6 Probability 0.1 .6 0.3 Call Duration (minutes) 3 4 5 6 Probability 0.14 0.6 0.12 0.14 Simulate for 100/500/1000 times. Conduct 3 such trials. It is proposed to add another telephone to the booth. Justify the proposal based on the waiting time of caller.Generate graphs to support your answer. 2. A baker needs to find out the cookies he need to bake each day. The probability distribution for the cookies customers is as follows: Number of customers/day 7 9 11 14 Probability 0.35 0.30 0.15 0.20 C...

System Analysis and Design (SAD)

Introduction to System Analysis and Design (SAD) System are created to solve Problems. One can think of the systemsapproch as an organised way of dealing with a problem. In this dynamic world , the subject system analysis and design, mainly deals with the software development activities. This post include:- What is System? What are diffrent Phases of System Development Life Cycle? What are the component of system analysis? What are the component of system designing? What is System? A collection of components that work together to realize some objectives forms a system. Basically there are three major components in every system, namely input, processing and output. In a system the different components are connected with each other and they are interdependent. For example, human body represents a complete natural system. We are also bound by many national systems such as political system, economic system, educational system and so forth. The objective of the system demands tha...

Advantages and Disadvantages of EIS Advantages of EIS Easy for upper-level executives to use, extensive computer experience is not required in operations Provides timely delivery of company summary information Information that is provided is better understood Filters data for management Improves to tracking information Offers efficiency to decision makers Disadvantages of EIS System dependent Limited functionality, by design Information overload for some managers Benefits hard to quantify High implementation costs System may become slow, large, and hard to manage Need good internal processes for data management May lead to less reliable and less secure data
