Active directory user accounts
Can we create multiple user accounts in active directory in a single shot? If so what is the command or tool used?
Why do we need memory protection and how the protection is eccomplished by the cpu?
The following Segment Registers are used to protect the Memory of CPU. It is related to Memory layout. such as stack, heap, code and Data of a process. segment registers: CS contains the segment of t...
This is done by using registers
We use DHCP Relays when DHCP client and server don't reside on the same (V)LAN, as is the case in this scenario. The job of the DHCP relay is to accept the client broadcast and forward it to the server on another subnet.
It is a Bootstrap Protocol that relays DHCP(Dynamic Host Configuration Protocol) messages between clients and servers for DHCP on different IP Network.using DHCP in a single segment network is easy. I...
1, give two real-world examples of closed systems. How well does each protct its software? 2, is each of the following an open system or a closed system? For each system, give an example of a real-world attack that has occurred. a. Pc b. Cell phone c. Ipod d. Xbox e. Kindle (an e-book reader)
What is the difference between 32 bit and 64 bit system?
It is just the size of the packages of information being handle, either 32 bits information packages or 64 bits information packages ( Data).
Processor:--a processor is the part a computer system that executes instructions .It is also called a cpu assembler: -- an assembler is a program that takes basic computer instructions and converts them into a pattern of bits that the computer's processor can use to perform its basic operations....
Assembler is a programming language which converts assembly language into machine language..and compiler is a language which convert high level language to machine language at once..whereas interpreter does that line by line
Processor is the one which executes the instructions.Compiler takes the source code and generates the assembly language code.Assembler takes the assembly language code and generates an object file.Lin...
StarVATion: starVATion is a resource management problem where a process does not get the resources it needs for a long time because the resources are being allocated to other processes. aging: aging is a technique to avoid starVATion in a scheduling system. It works by adding an aging factor to...
Starvation is a condition where a process does not get the resources it needs for a long time because the resources are being allocated to other processes. It generally occurs in a Priority based sche...
Condition for deadlock occurrence?
Deadlock can arise if four conditions hold simultaneously.Mutual exclusion: only one process at a time can use a resource.Hold and wait: a process holding at least one resource is waiting to acquire additional resources held by other processes.No preemption: a resource can be released...
The condition for the occurrence of deadlocks are Mutual Exclusion: At least one resource must be non-shareable.[1] Only one process can use the resource at any given instant of time. Hold and Wait ...
What is the meaning of register and main memory(ram) ?
And give the difference between them
Registers are present in the CPU and are directly associated with ALU.So,overhead involved in accessing information from the registers is the lowest
registers are used for storing the values.
eg ADD R1,R2
where R1,R2 are registers for performing the operation addition.
and main memory is also used for storing and registers are stored in main mem.
Differentiate between complier and interpreter?
An interpreter reads one instruction at a time and carries out the actions implied by that instruction. it does not perform any translation. but a compiler translates the entire instructions.
The compiler converts a high level language instruction into into machine language where as an interpreter converts the high level instruction into some intermediate form and after that, the instructi...
While running dos on a pc, which command would be used to duplicate the entire diskette?
Diskcopy Java thread states
Diskcopy command is used to duplicate the diskette,while running DOS on PC.
Paging is solution to external fragmentation problem which is to permit the logical address space of a process to be noncontiguous, thus allowing a process to be allocating physical memory wherever the latter is available.
Paging is a process of dividing the memory into equal sized logical blocks.When any page is required the operating system searches for that page in the secondary memory and copies that page to the mai...
Switching the cpu to another process requires saving the state of the old process and loading the saved state for the new process. This task is known as a context switch.Context-switch time is pure overhead, because the system does no useful work while switching. Its speed varies from machine to machine,...
Context switching is a process of storing and restoring the state of the CPU So that the execution of the process can be resumed from the same point where it had been switched. There are 3 situations ...
What is throughput, turnaround time, waiting time and response time?
Throughput number of processes that complete their execution per time unitturnaround time amount of time to execute a particular processwaiting time amount of time a process has been waiting in the ready queueresponse time amount of time it takes from when a request was submitted until the first...
Throughput: Number of processes completed per unit time. Turnaround time: The interval from time of submission of the process to the time of completion of the process. Waiting time: The sum of the pe...
Throughput:Total amount of work done in a unit of time.Waiting Time:The amount of time that is taken by a process in ready queue.Turn Around Time:The sum total of waiting time & execution time is ...
What is heartbeat in clustering?
Heartbeat cluster is a program that runs specialized scripts automatically whenever a system is initialized or rebooted.This cluster allows clients to know about the presence (or disappearance!) of pe...

What are the difference between win 2003 and win 2008 os?
Difference between 2003 server and 2008 server 1.we can install windows 2008 server either in full version(install all services& applications) or server core(only install minimal required services), ...
Primary difference is visualization management and power management tools.
Difference between logical and physical address space?
->the concept of a logical address space that is bound to a separate physical address space is central to proper memory management.Logical address generated by the cpu; also referred to as virtual address.Physical address address seen by the memory unit.->logical and physical addresses are...
logical address is the address generated by the CPU But physical add is the actual add of any process.
cpu basically generates logically address but physical address is the actual address of the process in the memory.
yes we can create multiple account in active directory user and computers.
