Question Bank
16.1 What is the primary use of tar command?
16.2 Describe the options available and their use in tar command.
16.3 What is the strategy you would follow to transfer your files over the network when you change your place of work? (Assume your new location has given you a login account.)
16.4 Write a shell script that will replicate the behavior of tar program.
16.5 What is the extent of compression achieved say for text files under UNIX?
Compare the efficacy of the compression when you zip with when you use compress command for text files.
16.6 Why compression of image files can be organized differently then say text files?
16.7 What is a lossy compression? Is the compression of a text file using compress command in UNIX lossy?
16.8 How does one attempt profiling of a program? Suppose a program is developed by having a main program which is used as a switching program to always call a function. Suggest a strategy that will find out which function engages the processor most?
16.9 Write two programs, one to perform matrix addition of int numbers and other to perform matrix multiplication of doubles. Use large matrices of 1000*1000.
Populate the matrices using some number generators. Check the running times of the two programs using the linux profiler.

Input Output (IO) Management:HW/SW Interface and Management of Buffers.

5.3 HW/SW Interface IO management requires that a proper set-up is created by an application on computer system with an IO device. An IO operation is a combination of HW and SW instructions as shown in Figure 5.8. Following the issuance of an IO command, OS kernel resolves it, and then communicates Figure 5.8: Communication with IO devices. with the concerned device driver. The device drivers in turn communicate with IO devices. The application at the top level only communicates with the kernel. Each IO request from an application results in generating the following: Naming or identification of the device to communicate. Providing device independent data to communicate; The kernel IO subsystem arranges for the following: The identification of the relevant device driver. We discuss device drivers in Section 5.3.1. Allocation of buffers. We discuss buffer management in Section 5.4. Reporting of errors. Tracking the device usage (is the device free, who is the current u...

Introduction to Operating Systems:Early History: The 1940s and 1950s

Early History: The 1940s and 1950s Operating systems have evolved over the last 60 years through several distinct phases or generations that correspond roughly to the decades (see the Operating Systems Thinking feature, Innovation).3 In the 1940s, the earliest electronic digital computers did not include operating systems.4, 5, 6 Machines of the time were so primitive that programmers often entered their machine-language programs one bit at a time on rows of mechanical switches. Eventually, programmers entered their machine-language programs on punched cards. Then, assembly languages—which used English-like abbreviations to represent the basic operations of the computer— were developed to speed the programming process. General Motors Research Laboratories implemented the first operating sys- tem in the early 1950s for its IBM 701 computer.7 The systems of the 1950s generally executed only one job at a time, using techniques that smoothed the transition between jobs to obtain maximu...

Input Output (IO) Management:IO Organization.

IO Organization In the previous section we discussed various issues that arise from the need to support a wide range of devices. To meet these varied requirements, a few well understood modalities have evolved over time. The basic idea is to select a mode of communication taking device characteristics into account or a need to synchronize with some event, or to just have a simple strategy to ensure a reliable assured IO. Computers employ the following four basic modes of IO operation: 1. Programmed mode 2. Polling mode 3. Interrupt mode 4. Direct memory access mode. We shall discuss each of these modes in some detail now. 5.2.1 Programmed Data Mode In this mode of communication, execution of an IO instruction ensures that a program shall not advance till it is completed. To that extent one is assured that IO happens before anything else happens. As depicted in Figure 5.1, in this mode an IO instruction is issued to an IO device and the program executes in “busy-waiting” (idli...
