Introduction to Operating Systems�

• Operating System is a software, which makes a computer to actually work.
• It is the software the enables all the programs we use.
• The OS organizes and controls the hardware.
• OS acts as an interface between the application programs and the machine hardware.
• Examples: Windows, Linux, Unix and Mac OS etc.
• OS is a resource allocator
• Manages all resources
• Decides between conflicting requests for efficient and fair resource use
• OS is a control program
• Controls execution of programs to prevent errors and improper use of the computer

An operating system performs basic tasks such as,

• Controlling and allocating memory
• Prioritizing system requests
• Controlling input and output devices
• Facilitating networking
• Managing file systems
• Computer system can be divided into four components
• Hardware – provides basic computing resources
• CPU, memory, I/O devices
• Operating system
• Controls and coordinates use of hardware among various applications and users
• Application programs – define the ways in which the system resources are used to solve the computing problems of the users
• Word processors, compilers, web browsers, database systems, video games
• People, machines, other computers

Diagrammatic View of Structure of OS

The structure of OS consists of 4 layers:

Hardware consists of CPU, Main memory, I/O Devices, etc,

• Software (Operating System

Software includes process management routines, memory management routines, I/O control routines, file management routines.

• System programs

This layer consists of compilers, Assemblers, linker etc.

• Application programs

This is dependent on users need. Ex. Railway reservation system, Bank database management etc.,

Evolution of OS:

• The evolution of operating systems went through seven major phases.
• Six of them significantly changed the ways in which users accessed computers through the open shop, batch processing, multiprogramming, timesharing, personal computing, and distributed systems.
• In the seventh phase the foundations of concurrent programming were developed and demonstrated in model operating systems.

Operating Systems functions:

• The main functions of operating systems are:
• Program creation
• Program execution
• Input/Output operations
• Error detection
• Resource allocation

Main Functions of OS�

• Process Management

A process is a program in execution. The operating system manages many kinds of activities ranging from user programs to system programs like printer spooler, name servers, file server etc. Each of these activities is encapsulated in a process. A process includes the complete execution context (code, data, PC, registers, OS resources in use etc.). ��

• Memory Management

To execute a program, it must he loaded, together with the data, it accesses in the main memory (at least partially). To improve CPU utilization and to provide better response tine to its users, a computer System normally keeps several programs in main memory. The memory management module of an operating system takes care of the allocation de-allocation of memory space to the various programs in need of this resource. �

• File Management

A file is a collection of related information defined by its creator. Computer can store tiles on the disk (secondary storage), which provide long term storage. Some examples of storage media are magnetic tape, magnetic disk and optical disk. Each of these media has its own properties like speed, capacity, data transfer rate and access methods. A file system normally organized into directories to ease their use. These directories may contain files and other directions. ��

• Device Management

A computer system normally consists of several I/O devices such as terminal, printer, disk, and tape. The device management module of an operating system takes care of controlling all the computer's I/O devices. It keeps track of I/O requests from processes, issues commands to the I/O devices, and ensures correct data transmission to/from an I/O ��

• Throughput :

Throughput is the amount of work that the system is able to do per unit time. it is �measured as the number of processes that are completed by the system per unit time. For example, �it ii processes are completed in an interval of t seconds, tie throughput is taken as n/t processes �per second during that interval. Throughput is normally measured in processes/hour. Here, it �is noteworthy that the value of throughput does not depend only on the capability of a system, �but also on the nature of jobs being processed by the system.

• Turnaround Time

From the point of view of an individual user, an important criterion is 'how �long it takes the system to complete a job submitted by him/her’. Turnaround time is the interval �from the time of submission of a job to the system for processing to the time of completion �of the job. Although higher throughput is desirable from the point of view of overall system �performance, but individual users are more interested in better turnaround time for their jobs. ���

• Response Time

Turnaround time is usually not a suitable measure for interactive systems, �because in an interactive system, a process can produce some output fairly early during its execution and can continue executing while previous results c11e being output to the user. Thus, another measure used in case of interactive systems is response time, which is the interval from the time of submission of a job to the system for processing to the time the first response for the job is produced by the system. ��

Types of OS:

Operating System can also be classified as,-

• Single User Systems
• Multi User Systems

Single User Systems: �

• Provides a platform for only one user at a time.
• They are popularly associated with Desk Top operating system which run on standalone systems where no user accounts are required.
• Example: DOS

Multi-User Systems: �

• Provides regulated access for a number of users by maintaining a database of known users.
• Refers to computer systems that support two or more simultaneous users.
• Another term for multi-user is time sharing .
• Ex: All mainframes and  are multi-user systems.
• Example: Unix

Some Popular Operating Systems

UNIX is a multitasking, multi-user computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas Mcllroy, and Joe Ossanna. UNIX operating system was first developed in assembly language, but by 1973 had been almost entirely recoded in C, greatly facilitating its further development and porting to other hardware.

MS-DOS was an operating system for x86-based personal computers. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s to the mid 1990s, until it was gradually 3uperseded by operating systems offering a graphical user interface (GUI), in particular by Various generations of the Microsoft Windows operating system.

Windows 7 is all about delivering on the failures of Vista.

• Performance improvements
• Boot-up time is faster than with Windows Vista, and Windows 7 resumes from sleep and reconnects to wireless networks more quickly.
• Search has been optimized to return results faster.
• Services that aren't in use are turned off, and memory is used more efficiently than in Vista, increasing performance.
• USB devices are ready for use in less time after you plug them in.
• Power management
• Automatically dims the screen after a period of inactivity when on battery power
• Powers off unused ports
• Uses less power for DVD playback
