Analysis and implementation of algorithms for memory allocation in operating system
Explain First- t and best- t methods are used in memory allocation in operating systems.
Task 1) Produce a owchart for each of the two algorithms, and use your owchart to detail the steps in the algorithms.
Task 2) Implement each of them in a programming language that you are familiar with (e.g. C or C++),
Task 3) Run your programs with three different cases for each of the two algorithms, and record your input and output for each of the three runs, and compare the e ciency of both algorithms.
Suppose further that a single processor system can solve the problem in 106 seconds (about 11.6 days). So, on average, the single processor system
The program you develop should take a message given as a command line argument and append it to a file (also specified on the command line). The file should have no permissions, both before and after the message is appended. Of course, the file sh..
Why does concurrency lead to programming errors that are difficult to locate? Give as concrete an example as you possibly can?
Specify the order in which processes execute and determine the mean process turnaround time for each of the scheduling algorithms.
How many page faults are generated by the following arrayinitialization loops, using LRU replacement, and assuming page frame 1 has the process in it, and the other two are initially empty.
The following four requests could come in to the operating system as it is running on computer system: Clock in computer has just "ticked", and we require to update seconds counter.
Consider the followimg nested loop contruct. Categorize the efficiency in terms of the variable n using "big-O" notation. Suppose the statements represented by the elipsis
Discuss how many minimum length Ethernet frames can a ten Mbps switch port forward in one second, assuming no collision?
Discuss what roles do firewalls and proxy servers play in network security? Determine the importance of maintaining security on a LAN?
While working with a 2.5 GHz pipelined MIPS processor which has a L2 cache unit miss penalty of 10 ns and a memory miss penalty of 50 ns, determine the Effective CPI for a program with a 0.4% instruction miss rate, 11.4% data miss rate, a L2 miss rat..
