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.

OPERATING SYSTEM
An Operating System (OS) is an interface between computer user and computer hardware and controls the execution of all kinds of programs. Operating System (OS) is one of the core software programs that runs on the hardware and makes it usable for the user to interact with the hardware so that they can send commands (input) and receive results (output). It provides a consistent environment for other software to execute commands. OBJECTIVES OF OPERATING SYSTEM 1. Interface between the user and the hardware 2. Coordinate hardware components 3. Provide environment for software to function 4. Provide structure for data management 5. Monitor system health and functionality FUNCTIONS OF OPERATING SYSTEMS: Following are some of important functions of an operating System. 1. Memory Management 2. Processor Management 3. Device Management 4. File Management 5. Security 6. Control over system performance 7. Job accounting 8. Error detecting aids 9. Coordination between other software and users COMPUTER-SYSTEM ARCHITECTURE: A computer system can be organized in a number of different ways, which we can categorize roughly according to the number of general-purpose processors used 1. Single-Processor Systems 2. Multiprocessor Systems 3. Clustered Systems OPERATING SYSTEM STRUCTURE: The design of operating system architecture traditionally follows the separation of concerns principle. This principle suggests structuring the operating system into relatively independent parts that provide simple individual features, thus keeping the complexity of the design manageable. A. Simple Structure B. Layered Approach C. Micro-kernels D. Modules
Lab programs implementations using C language in Window environment.
This lab complements the operating systems course. Students will gain practical experience with implementing concepts of operating systems such as system calls, CPU scheduling, process management, memory management, file systems using C language in Window environment.
