Job control is a system function and is handles by an operating system. The CPU does not candle any job control functions. Job control is on a much higher level that the CPU is not designed to handle.

What is the main advantage of multiprogramming?
Multiprogramming increases CPU utilization by organizing jobs so that the CPU always has a job to execute.
What is the differences between the job scheduling and process scheduling?
Jobs or processes are the same. Whereas, Job scheduler and CPU scheduler are two different terms. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler. While Job scheduler selects the processes from the job pool (Job pool is on the Hard disk) and load them in to the memory (Main Memory or RAM) for execution. in other hand CPU scheduler selects among the processes (in RAM) that are ready for execution and allocates the CPU to one of them. Hope I got it right and answered your query. Sorry for any mistakes as I'm not perfect as well. :) Cheers, KV
What are different types of CPU scheduling algorithms?

When we say a system is a multiprogramming system?
Multiprogramming is collecting several jobs in a job pool and the OS selects the job from the pool so that the CPU has one job to execute , in case of any IO request for the job in execution the CPU switches to another job here switching is less compared to multitasking.So a computer system which allows such type of switching in between jobs is called a multiprogramming system. Please make note that multitasking is done by user but multiprogramming is done by operating system only.
What is CPU sheduling algorithm?
Basically,this is a need in case of multiprogramming.For optimum utilization of CPU it should be utilised in the meanwhile time when some process is in waiting state for some I/O or waiting for some event to occur. So,for this many programs should be in memory in waiting state so that CPU can be allocated to some other process for optimum utilization of CPU. A schedule(time table in broad sense) which will decide Cpu will be allocated to which process when some previous process is in waiting state. Now this schedule is designed according to some criteria(algorithm) to decide CPU will be allocated to which process. Some Algorithms: 1.First Come First Serve(FCFS) 2.Shortest Job Scheduling(SJS) 3.RoundRobin Scheduling(RRS)
The control unit is one component of the?
its located in the central processing unit which is your microprocessor in simple words. its job is to check device status and control computer components
Which hardware is an eye of computer?
, Control Unit is an hardware eye of computer. Well, as you might already know that CPU(Central Processor Unit) is termed as brain of computer. CPU consists of three parts as follows 1. ALU(Arithmetic and Logic Unit) 2. Memory 3. CU(Control Unit) Job of control unit is to monitor all activities and make sure that everybody is doing what they are supposed to do. Regards, Prime
What is the job of the cooling fan and heat sink?
They're used to help keep the processor on the motherboard inside the Central Processing Unit (CPU) from overheating. Both are necessary: the fan actually protects all the devices inside the CPU from overheating, while the heat sink is used especially for the processor as it gets overheated quickly.
The purpose of a CPU?
A Central Processing Unit is the main processor in a computer that processes all the logic statements put to it. It is responsible for all the processing of the computer unless there is another process that does the job like a Graphics Processing Unit or Physics Processing Unit.
How do you describe a CPU?
CPU is stand for Central Processing Unit. The CPU is divided in 2 parts such as CU, ALU and other Registers, Instruction Decoder and Bus Interface. There are mainly 6 types of Registers instruction decoder is decode the instruction There are 3 type of bus Address Bus, Control Bus, Data Bus.
What is the central processing unit of the computer?
The CPU's job is to send out bits of memory to other places in your memory and each memory slot has a code which the CPU uses to find the location in the memory and then send out a 1 or a 0 to that spot. And if you've ever used a flip flop that is what it is and that is what the CPU changes.
Technician is assembling a new computer Which two components are often easier to install before mounting the motherboard in the case?
Before mounting the motherboard in the case I like to install the CPU and CPU fan/heatsink on to the motherboard. In fact, it is recommended to install the CPU & heatsink while the motherboard is still our of the case to make the job easier.
What is a multi program system?
A group of jobs that are ready to be executed is called job pool. Since there is more than one job that can be executed, it is possible for the operating system to make a decision about which job to execute next. That decision keeps CPU utilization as high as possible. In general, it is not possible for a single user to keep CPU or I/O devices busy at all times. Multiprogramming allows the system .to increase CPU utilization by ensuring that the CPU always has a job to execute. The CPU has a pool of jobs. When the currently executing job has to wait (if it is performing some I/O), it is removed from the CPU- Another job is selected and the CPU now executes it. This process ensures that CPU is always executing a job if there is a job to execute. In a non-multiprogrammed system, if a job had to wait for an I/O operation, CPU would also have to wait until I/O was finished. Hammad Ali

What is the difference between control unit and memory unit?
Control UnitAll computers follow instructions that are given to it in a program. These instructions are in a particular order in the program, and following them, and carrying them out, will mean that the computer has accomplished whatever task it was meant to do. Something in the computer has to manage the instructions and make sure that all the other parts of the processor do what they should be doing. This is the job of the control unit.The control unit has three jobs:It has to decide which instruction to carry out next and then go and get it.It has to decipher the instruction, in other words it has to work out what needs to be done to carry the instruction out.It has to tell other parts of the processor what they should do so that the instruction will be carried out.Memory UnitThe third part of the processor is where everything that the processor is going to use is stored. This includes all the program instructions and all the data needed to carry out those instructions. One of the jobs of the control unit is to be able to find the information stored there when it is to be used. The parts of the operating system, which the computer is using at the time, also need to be stored in memory.
What is the difference between the job scheduler the CPU scheduler?
1. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler. 2. Job scheduler selects the processes from the job pool and load them in to the memory for execution. in other hand CPU scheduler selects among the processes that are in ready to execute and allocate the CPU to one of them. 3. CPU scheduler is faster than the process scheduler.
How do you get rid of bees inside walls?
Unless you are experienced this is not a job to do yourself. Contact a beekeeper or a pest control officer.
