SHELL PROGRAMMING
A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter.The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. This file consists of executable simple shell programs, which includes : 1.Program to find Average of Three Numbers 2.Program to Implement If Statement 3.Program to find Largest of Three Numbers 4.Program to Find whether the Character is Vowel or Not 5.Program to Print Factorial of a Number 6. Program to Print Numbers from 1 to 10 using While Loop 7. Program to Print an Array YOU CAN DIRECTLY COPY THE CODE AND EXECUTE AND RUN THE ABOVE PROGRAMS IN UNIX OS.

Transition in Prokaryotes
A prokaryote is a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. Prokaryotes are divided into two domains, Archaea and Bacteria. Species with nuclei and organelles are placed in the third domain, Eukaryota. Prokaryotes reproduce without fusion of gametes. The first living organisms are thought to have been prokaryotes. This attachment is a short note of transition in prokaryotes .
Unix Operating System
Unix is an operating system with set of programs that act as a link between the computer and the user. This file consists unix Architure, unix file system, vi command and unix commands with description,syntax and examples.
scheduling Algorithm
Here are some assignment questions on scheduling algorithms, which includes First Come First Serve(FCFS) and Shortest Job First(SJF). In SJF questions are given both on Preemptive and Non-Preemptive Scheduling Algorithm.
Interhalogens
An interhalogen compound is a molecule which contains two or more different halogen atoms (fluorine, chlorine, bromine, iodine, or astatine) and no atoms of elements from any other group. This document explains the interhalogen compounds with suitable examples using VSEPR theory
Adiabatic Demagnetisation
The lowest temperature near absolute zero can be reached by boiling liquid hydrogen and helium under pressure . K. Onnes attained a temperature of 0.82K by evaporating liquid helium under a pressure of 0.013mm of mercury. The lowest temperature 0.7K in this way was reached by Kessam by reducing the pressure on the surface of liquid helium to 0.036mm of mercury by extremely powerful pumps. The possibility of still lower temperature was explored by Deobye and Giaque in 1926 independently by Adiabatic Demagnetisation of paramagnetic salts.
