Advanced Operating System- IntroductionDebasis Das
Introduction to Advanced Operating systems. Many university courses run advanced/ distributed operating system courses in their 4 year engineering programs. This is based on WBUT CS 704 D course but matches many such courses run by different universities. If you need to downloaad this presentation, please send me an email at ddas15847@gmail.com

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
4. System Software- Performs essential operation tasks
Operating system
Utility programs
Application Software - Performs specific tasks for
users
Business application
Communications application
Multimedia application
Entertainment and educational software
Driver Programs (Device Driver)
small program that allows a specific input or
output device to communicate with the rest of the
computer system
5. user / application programs
programs used by the users to perform a
task
system programs
an interface between user and computer
driver programs
communicate I/O devices with computer

Operating System
Computer
Hardware
8. A collection of programs which control the resources of a
computer system.
Written in low-level languages (i.e. machine-dependent).
An interface between the users and the hardware.
When the computer is on, OS will first load into the
main memory.
9. Operating
System
Device configuration
Controls peripheral devices connected to the computer
File management
Transfers files between main memory and secondary
storage, manages file folders, allocates the secondary
storage space, and provides file protection and
recovery
Memory management
Allocates the use of random access memory (RAM) to
requesting processes
Interface platform
Allows the computer to run other applications
10. Best use of the computer resources.
Provide a background for user’s programs to execute.
Display and deal with errors when it happens.
Control the selection and operation of the
peripherals.
Act as a communication link between users.
System protection.
11. Common Operating Systems and
Their Differences
Network Operating System
UNIX / Linux / MS Windows2000 Server
Desktop Operating System
MS Windows 9X/Me / Mac OS / DOS
Mobile Operating System
Palm OS and Pocket PC
12. Examples
Common operating systems:-
WINDOW
used in IBM compatible microcomputers
UNIX
multi-user, multi-tasking OS used in minicomputers and
microcomputers
VAX/VMS
used in DEC’s VAX series of minicomputers
14. Cross-Platform Issues
Cross-Platform
developing software for, or running software, on more
than one type of operating platform.
Machine-independent Programming Languages
JVM
Makeup Languages
HTML
XML
Advantages
cost-effective
saves time
develop the program on different computers
15. A part of operating system to control disk operation.
2 parts
Small system data
Keep track of key information of the disk
Data area
Where data file is stored
16. 3 parts:-
boot/boot record
i.e. a short program for loading DOS into
computer’s memory
File allocation table (FAT)
i.e. record the status of each part of the disk and
keep track of all data
Root directory
i.e. record the filename, size of the file , date and
time
17. Efficient
time spent to execute its programs should be short
Small in size
memory occupied should be as small as possible
Reliable
18. Type of Operating System
Batch processing.
Real time processing.
Time sharing processing.
19. Batch processing
Jobs, together with input data, are fed into the
system in a batch.
The jobs are then run one after another.
No job can be started until previous job is
completed
20. Immediate response is needed.
For example
anti-missile defense system
airplane landing control system
interrupt error in computer system
21. Each user is given a time slice to interact with
the CPU.
The size of the time slice will depend on the
system.
Each user is served in sequence.
24. To handle 2 or more programs at the same time from a
single user ‘s perception
CPU can only perform one task at a time, however, it
runs so fast that 2 or more jobs seem to execute at the
same time
25. 2 or more programs store in the main
memory at the same time
When one job reeds to wait (e.g. I/O
operation), CPU switch to another job to
execute
When the first job finishes waiting, CPU will
get back the first job to execute
26. Use 2 or more CPUs to handle jobs
Computer networking
Job 1 Job 2
Job 3
Job 4
Job 1
Job 2
Job 3
Job 4
CPU 1 CPU 2 CPU 1
time time
without multiprocessing
with multiprocessing
27. Buffering
A temporary storage area (buffers) to read data from
input device or send data to the output device
Keep CPU busy
Because I/O operation is slow
28. a larger buffer from hard disk
buffer store the data through I/O operation
because I/O operation is slow and CPU
operation is fast
