What are the main differences between the three I/O models (Programmed I/O, Interrupt-driven I/O, and DMA) and what are their strength and weakness?
Write the function product which consumes a list of numbers and returns the product of those numbers. Make sure you follow the design recipe!
Give an example of how an operating system may use a combination of memory technologies with varying speeds, capacities and costs to achieve overall good performance at acceptable cost.
Write a program that takes a list of command line arguments, each of which is a full path of a command (such as /bin/ls, /bin/ps, /bin/date, /usr/bin/who, /bin/unameetc). Assume the number of such commands is N, your program would then create N child processes, each of which executing one of the N commands. You should make sure that these N commands are executed concurrently, not sequentially one after the other. The parent process should be waiting for each child process to terminate. When a child process terminates, the parent process should print one line on the standard output stating that the relevant command has completed successfully or not successfully (such as"Command /bin/who has completed successfully"). Once all of its child processes have terminated, the parent process should print "All done, bye-bye!" before it itself terminates.
hey i am wondering if you guys provide help for programming in Ada language
A program on your computer has established a TCP connection with a remote Web
server. It sends three TCP segments to the server, of length 200 bytes, 300 bytes and 400 bytes,
respectively. The sequence number of the first segment is 9042.
(a) What are the sequence numbers of the second and third segments your computer
sends? If all three segments are acknowledged, what should the ACK numbers of the ACK
segments be?
(b) Each of the three segments is the payload of a separate IP packet. For each of those
packets, what are the Version, Total Length, and Protocol fields? (Assume we are using IPv4.)

Waterfall, V-shape, and Rapid Application Development (RAD) are among well-established software process models that have been used to develop software. Typically, software process model involves specification, design, implementation and testing the software system. Lately, software companies have started to move to Agile process model in order to cope with the rapid demand of releasing quality software faster to the market. Looking at this latest trend, discuss Agile model and compare it with Waterfall model. Provide an analysis on how software project management aspect is implemented in an Agile model.

hey i need to learn how to create a number generator for pascal. but not a normal one, that just gives you a random number when you click the exe file. i mean one that once clicked, 10 numbers come up spinning numbers from 1 to 9. and after 5 seconds, one by one, from left to right, they stop on a random number. and also everytime you click the .exe it will spin a different 10 digit number everytime.
