What is Information? It is a form of knowledge that we acquire through education, communication, practical experience, research, analysis or ratiocination.
It consists of data, facts, and conclusions.
To the scientist concerned with communications theory it is the opposite of entropy.1
To the computer scientist it is any data that can be expressed as a sequence of ones and zeros

15. Consider the extended LAN connected using bridges B1 and B2 in the given Figure. a.)A sends a packet to C. (b) E sends a packet to F. (c) F sends a packet to E. (d) G sends a packet to E. (e) D sends a packet to A. (f) B sends a packet to Fcs
1. why it is much easier to do algorithm analysis than it is to do algorithm design. Your answer should include an example of a problem for which an algorithm already exists and all that is required of you is to analyze it versus another problem for which no algorithm exists and you are required to design one.
v When one does algorithm analysis, there is already an algorithm that is to be analyzed. What one does then is to apply the rules of analysis as we had studied them in class – rules for

Operation on a Process
- Process creation: A user requests, and already running process can creates new processes. Parent process creates children processes using a system call, which, in turn create other processes, forming a tree of processes.
- Process pre-empting: A process pre-empted if I/O event or timeout occurs. Then process moves from running state to ready state and CPU loads another process from ready state to running state, if available.
- Process blocking: When a process needs I/O event
