2. Introduction
What is an Operating System?
Mainframe Systems
Desktop Systems
Multiprocessor Systems
Distributed Systems
Clustered System
Real -Time Systems
Handheld Systems
Computing Environments
Operating System Concepts
3. What is an Operating System?
A program that acts as an intermediary
between a user of a computer and the
computer hardware.
Operating system goals:
Execute user programs and make solving user problems easier.
Make the computer system convenient to use.
Use the computer hardware in an efficient
manner.
Operating System Concepts
4. Computer System Components
1. Hardware – provides basic computing resources
(CPU, memory, I/O devices).
2.Operating system – controls and coordinates the use
of the hardware among the various application
programs for the various users.
3.Applications programs – define the ways in which the
system resources are used to solve the computing
problems of the users (compilers, database systems,
video games, business programs).
4.Users (people, machines, other computers).
Operating System Concepts
5. Operating System Definitions
Resource allocator – manages and allocates
resources.
Control program – controls the execution of
user programs and operations of I/O devices .
Kernel – the one program running at all
times (all else being application programs).
Operating System Concepts
6. Mainframe Systems
Reduce setup time by batching similar jobs
Automatic job sequencing – automatically
transfers control from one job to another.
First rudimentary operating system.
Resident monitor
initial control in monitor
control transfers to job
when job completes control transfers pack to monitor
Operating System Concepts
9. Multiprogramming
We can execute Multiple Programs on the System at
a time
Multi-programming the CPU will never get idle.
Operating System Concepts
10. OS Features Needed for Multiprogramming
I/O routine supplied by the system.
Memory management – the system must
allocate the memory to several jobs.
CPU scheduling – the system must choose
among several jobs ready to run.
Allocation of devices.
Operating System Concepts
11. Time-Sharing Systems–Interactive Computing
The CPU is multiplexed among several jobs
that are kept in memory and on disk.
A job swapped in and out of memory to the
disk.
On-line system must be available for users to
access data and code.
Operating System Concepts
12. Parallel Systems
Multiprocessor systems with more than on CPU in
close communication.
Tightly coupled system – processors share memory
and a clock; communication usually takes place
through the shared memory.
Advantages of parallel system:
Increased throughput
Economical
Increased reliability
graceful degradation
fail-soft systems
Operating System Concepts
13. Parallel Systems (Cont.)
Symmetric multiprocessing (SMP)
Each processor runs and identical copy of the operating
system.
Many processes can run at once without performance
deterioration.
Most modern operating systems support SMP
Asymmetric multiprocessing
Each processor is assigned a specific task; master processor
schedules and allocated work to slave processors.
More common in extremely large systems
Operating System Concepts
15. Distributed Systems
Distribute the computation among several
physical processors.
Loosely coupled system – each processor has its
own local memory; processors communicate with
one another through various communications
lines, such as high-speed buses or telephone
lines.
Advantages of distributed systems.
Resources Sharing
Computation speed up – load sharing
Reliability
Communications
Operating System Concepts
16. Distributed Systems (cont)
Requires networking infrastructure.
Local area networks (LAN) or Wide area
networks (WAN)
May be either client-server or peer-to-peer
systems.
Operating System Concepts
18. Clustered Systems
Clustering allows two or more systems to share
storage.
Provides high reliability.
Asymmetric clustering: one server runs the
application while other servers standby.
Symmetric clustering: all N hosts are running the
application.
Operating System Concepts
19. Real-Time Systems
Often used as a control device in a dedicated
application such as controlling scientific
experiments, medical imaging systems,
industrial control systems, and some display
systems.
Well-defined fixed-time constraints.
Real-Time systems may be either hard or soft
real-time.
Operating System Concepts
20. Real-Time Systems (Cont.)Hard real-time:
Secondary storage limited or absent, data stored in short term
memory, or read-only memory (ROM)
Conflicts with time-sharing systems, not supported by
general-purpose operating systems.
Soft real-time
Limited utility in industrial control of robotics
Useful in applications (multimedia, virtual reality) requiring
advanced operating-system features.
