What would be the effect of the system running too many input output jobs?
Each program that is waiting for Input/Output is put into a blocked state inside the computer. The programs only enter the Ready/Running state when they are available to perform I/O operations. Because of DMA (Direct Memory Access) and because of the fact that most processes will be blocked, the effect of having a reasonable number of I/O programs will be minimal to the performance of your machine. If you have an extravagant number of I/O programs, your computer will see significantly slower performance.
When multiple programs or processes are running on a Unix machine how do you find out much memory is being used by each program?
to find out the memory of each processes running on our unix/ Linux box type "PS -aux | more" would list u all the processes running with their respective processor id's (pid) and the memory used by the respective programs ... if u are running out of memory what we can do is note down the pid which is taking lot of memory and if u feel the process is not so important for u then use the command "killall"to quit or stop that particular process I am using red-hat Linux, here u can use a top command to c the amount of memory utilized by each running processes. You can use "top" or the native "prstat" in Solaris. In order to see how much memory is used by a process, not including that shared with other processes ( through shared libraries ), you can execute "pmap -x $pid" giving your processes PID.
What happens to the transport layer PDU as the packet moves through the network?
manages the data transport between the processes running on each end host
How is true multi tasking achieved?
True multi-tasking is achieved through parallel processors. If you only have one processor, only one task can execute at a time. You can still multi-task by rapidly switching between all the running processes, but you cannot have two processes running simultaneously. With two or more processors running in parallel, you can.
What are the science processes and describe each?

During which of the following processes is no ATP produced a glycolysis b Krebs cycle c ets d ATP is made during each of the processes above e ATP is not made during any of the processes?
the answer is D ATP is made during each of the processes
What is the meaning of maltitasking?
Multitasking is the simultaneous running of several processes by a single machine. PCs are an example of multi-tasking machines. They are capable of running several programs at the same time as well as numerous background tasks such as network control, file management, printer control and many more. The processes are normally under the control of housekeeping software that allocates computer resources to each of the tasks as they are needed.
Can you get the maze block in Pokemon diamond?
Yes. There are 5 different ones. Each block has a different spot blocked. One doesn't have any blocked.
Could each of the agile processes be described using the generic framework activities?
Yes, each of the agile processes can be described using the generic framework activities.
How is energy and the kinetic theory involved in each of these six processes?
What six processes would be a good comeback question. Name the processes and one of us will have a stab at it.
What are all the process that are presently running?
The 'ps' command will give you all the currently running processes. Each Unix system may have slightly different options to list them. The most common would be: ps -ed or ps -ef or ps -el depending on how much information you want to see.
What do you mean by real and pseudo-parallelism?
Pseudo-parallelism is the parallelism effect where a single processor creates a illusion of parallel processing by switching processes(or context) at very small intervals such that it is unnoticable to the user. This creates the effect that multiple processes(threads or programs) are running simultaneously. What actually happens is, each process is given a finite time(very small) and the process executes its instruction during this period. At the end of this period, context switching occurs and the Operating System allocates a finite time for another process. The next process may or may not be allocated the same amount of time and the time allocated to each processes depend upon their priority. On the other hand, Real parallelism applies to multi-processor(or multicore) system where each processor(or core) initiates its own sets of processes. Note that, it is possible that when a multi-core processor is performing Real Parallelism, each core might be performing Pseudo-parallelism amongst the processes(or threads) it is currently running.
