What is the purpose of the clock in a computer?
Clock speed determines at what speed the CPU works, in fact faster or more the clock speed faster is the processing speed. Every CPU is designed to operate at a definite speed, Over clocking can sometimes lead to malfunction.
How do you calculate the CPU burst time in a computer system?
The CPU burst time in a computer system is typically calculated by measuring the time it takes for a process to complete its execution on the CPU. This can be done using tools like performance monitoring software or by analyzing the timestamps of when a process starts and finishes running on the CPU. The CPU burst time is an important metric for understanding the performance of a computer system and can help in optimizing resource allocation and scheduling of processes.
What are the scheduling criteria for CPU scheduling?
CPU Scheduling Criteria: There are many scheduling algorithms and various criteria to judge their performance. Different algorithms may favor different types of processes. Some criteria are. as follows: • CPU utilization: CPU must be as busy as possible in performing different tasks. CPU utilization is more important in real-time system and multi-programmed systems. • Throughput: The number of processes executed in a specified time period is called throughput. The throughput increases .for short processes. It decreases if the size of processes is huge. • Turnaround Time: The amount of time that is needed to execute a process is called turnaround time. It is the actual job time plus the waiting time. • Waiting Time: The amount of time the process has waited is called waiting time. It is the turnaround time minus actual job time. • Response Time: The amount of time between a request is Submitted and the first response is produced is called response time. A CPU scheduling algorithm should try to maximize the following: • CPU utilization • Throughput A CPU scheduling algorithm should try to minimize the following: • Turnaround time • Waiting time • Response time by manish kumar gnit g.noida
What purpose of the CPU battery?
It's not really a CPU battery but it keeps your Date and Time, etc, in memory so the system will be ready for start up.
What is the CPU temperature range?
The Cpu Temperature is The Maximum/Minimum temperature of Cpu, You have to be inside these limits for your Cpu Safety
What is the relationship between turnaround CPU cycle time and waiting time?
turn around time is the time taken for completing a particular job. It is the sum of CPU cycle time and waiting time, as these two contribute to the total turn around time
Is the CPU updating cycle another name for the CPU processing cycle?
true
What is a CPU cycle?
The sequence of steps that a CPU performs.Also known as fetch-decode-execute cycle.
3 types of DMA transfer modes?
· Block transfer DMA controller takes the bus control by CPU. CPU has no access to bus until the transfer is complete. During this time CPU can perform internal operations that do not need bus. This is a common and popular method with modern microprocessors. · Cycle stealing This is a word-by-word transfer based on CPU cycle stealing. When DMA steals a cycle, CPU is stopped completely for one cycle. Cycle stealing is not an interrupt. CPU pauses for just one machine cycle. This type of transfer takes a period of time. Some major steps of DMA cycle stealing in order to transfer data to and form memory are: · DMA needs control of the CPU · DMA must use the bus only when the CPU does not need it · CPU is suspended by DMA just before it needs to use the bus · CPU pauses for one bus cycle · DMA transfers one words and then returns the control to CPU · The overall effect is to cause the CPU to execute more slowly · Interleaved DMA. It is similar to block transfer technique, here DMA controller takes the control of system bus only when CPU is not using it. For example, performing an ALU operation or incrementing a counter. The data transfer by this kind of method takes a period of time.
What refers to the amount of time it takes a CPU to execute an instruction and store the result?
The execution cycle.
What is a cycling machine?
Each time the CPU executes an instruction, it takes a series of steps. The complete series of steps is called a machine cycle. A machine cycle can be divided into two smaller cycles. These are instruction cycle and execution cycle. Instruction cycle: In instruction cycle CPU takes two steps-- 1. Fetching: Before the CPU can execute an instruction, the control unit must retrieve or fetch a command or data from the computer's memory. 2. Decoding: Before a command can be executed, the control unit must decode the command into instruction set. Execution cycle: In execution cycle CPU also takes two steps-- 1. Executing: When the command is executed, the CPU carried out the instructions in order by converting them into macrocode. 2. Storing: The CPU may be required to store the result of an instruction in memory.
Is the machine cycle same as the CPU?
yes
How does DMA module communicate with CPU?
DMA can communicate with CPU using Cycle stelaing process
In what all situations DMA is used?
DMA (Direct Memory Access) can be used during the CPU's "busy time", such as when the CPU is processing a read/write cycle, the DMA will take over to perform other tasks while the CPU is busy.
How many steps does CPU processing cycle have?
4
How many steps does the CPU processing cycle have?

What is bus cycle in a microprocessor?
Bus cycle is a single transaction between the main memory and the CPU.
