AN INTRODUCTION TO OPERATING SYSTEMS : CONCEPTS AND PRACTICE - PHI LearningPHI Learning Pvt. Ltd.
The book, now in its Fifth Edition, aims to provide a practical view of GNU/Linux and Windows 7, 8 and 10, covering different design considerations and patterns of use. The section on concepts covers fundamental principles, such as file systems, process management, memory management, input-output, resource sharing, interprocess communication (IPC), distributed computing, OS security, real-time and microkernel design. This thoroughly revised edition comes with a description of an instructional OS to support teaching of OS and also covers Android, currently the most popular OS for handheld systems. Basically, this text enables students to learn by practicing with the examples and doing exercises.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

4. Spooling
• SPOOL : Simultaneous Peripheral Operation On-Line
• A spool is a buffer that holds output for a device, such
as a printer, that cannot accept interleaved data streams
• Spooling overlaps input of one job with the
computation of other jobs
• The spooler may be reading the input of one job while
printing the output of a different job as shown in next
slide

5. Spooling
Disk
I/O
Online
CPU
Card Reader Line Printer
6. Spooling Technique
• A high speed device like a disk is interposed
between a running program and a low speed device
involved with the program input/output
• Communication between a high speed device and
low speed device is isolated
• High speed device transfers the data to the spool
• Low speed device gets the data from the spool
6
7. Advantages
• Performance of the system is increased
• CPU and I/O devices work more efficiently
• Leads naturally to multiprogramming
• Also used for processing data at remote sites
7
8. What is a Buffer ?
A buffer is an area of main memory for holding
data during input and output data transfers
8
9. Buffering
• Overlaps the I/O of job with that of its own
computation
• After the data have been read and the CPU is
about to start the operation, the input device is
instructed to begin the next input operation
• Both the CPU and I/O device are busy
9
11. Buffering
• By the time CPU is ready for next operation, the
input device would have finished reading it
• CPU creates data and puts into a buffer until an
output device can accept it
11
13. Input Buffering
• Data transferred by an input channel is stored in
the buffer
• After the data transfer, the processor access the
data from the buffer
13
14. Why Buffering ?
Because of three reasons…
• To cope with a speed mismatch between the
producer and consumers of a data streams
• To adopt between devices that have different data-
transfer sizes
• To support copy semantics for application I/O
14
15. Summary
• Spool: Simultaneous Peripheral Operation On-Line
• Spooling overlaps the I/O of one job with the computation
of another job
• A high speed device like a disk is interposed between a
running program and a low speed device
• Buffer is an area of main memory, which is used to store
data temporarily during input and output data transfers
• Spooling and buffering increases the system performance

16. Frequently Asked Questions
1. Define the terms Spooling and Buffering
2. Explain in detail Spooling and Buffering

17. Quiz
1. Buffering overlaps the I/O of a job with its own
computation
• True
• False
2. SPOOL stands for simultaneous peripheral
operation off line
• True
• False
