What is meant by task processing time?
A task can refer to a process or a part of a process.The processing time of a task is the actual amount of time in which the CPU was processing instructions for that task.
Can you check CPU usage from task manager?
YES Just look under the performance tab and you will see cpu usage.
What is it called when a device requests the CPU to perform a task?
interrupt controller
What part of the computer handles the task of calculating formulas and editing?
CPU
What option allows you to view processes sorted by how CPU hungry they are?
Check your Task Manager, under the processes tab. You can sort it by Memory or CPU.
When a device needs the CPU to perform a task what does it need to do?
The device needs to signal the CPU to get its attention. It typically does this through an interrupt request line (IRQ).
A CPU uses a series of actions to complete a task What is this series of actions called?
Pipeline
What do you use task manager for?
For Emergency shutdown of programs, check the performance of your CPU etc.
What tab will tell you which programs are most demanding on your CPU?
Depending on what OS (operating system) you are using. i will use windows for my answer. you can either press CTRL + ALT + DEL and select Task Manager from the list that appears. or you can right click on your task bar (the one at the bottom of your screen) and select task manager from there. once Task Manager is open navigate to the processes tab and then click the CPU to sort the list by descending order of CPU % if you are wanting to know this because the computer is running slow it might also be an idea to check how much memory it is using, by clicking on the memory normally located next to CPU.
When will you have two CPU usage history graphs in task manager?
When you have two CPU's. You are shown one graph per processor (core) that your machine has. Ex, a quad core i.e. a machine with 4 processors will have four CPU usage history graphs.
How process and threads relate to CPU architecture?
A process is a program in execution,it needs resources like CPU time,memory,files and i\o devices to accomplish its task. Threads are lightweight process
Is two programs can literally multitask if a system has a single CPU?
literally yes - but practically the CPU is jumping from one task to the other and back until he finished - so both tasks are slowed down
