What is relationship between a guest operating system and a host operating system in a system like VMware?
A host operating system is the operating system that is in direct communication with the hardware. It has direct hardware access to kernel mode and all of the devices on the physical machine. The guest operating system runs on top of a virtualization layer and all of the physical devices are virtualized. A host operating system should be as modular and thin as possible to allow the virtualization of the hardware to be as close to the physical hardware as possible, and so that dependencies that exist in the host operating don't restrict operation in the guest operating system.Read more: What_is_the_relationship_between_a_guest_operating_system_and_a_host_operating_system_in_a_system_like_VMware_what_factors_need_to_be_considered_in_choosing_the_host_operating_system
Is the operating system a set of instructions that direct the computer to accomplish specific tasks?
yes shiraz yes
Why it is difficult to support direct access to files with variable-length records?
For direct access with variable-length records, it's virtually impossible to access a record directly because the address of the desired record can't be easily computed. In order to access a record, the File Manager must do a sequential search through the records. The File Manager could search forward from the CBA-if the address of the desired record was between the CBA and the end of the file. Otherwise, the search would start from the beginning of the file. It could be said that this semi-sequential search is only semi-adequate
What is absolute code in operating system?
Program code in a form suitable for direct execution by the central processor, i.e. code containing no symbolic references.
Needs of operating system?
Operating System is a system software which allow us to have a direct interface with the hardware without knowing the complexity involved in the background. In simply words, it puts use of computer hardware. To the point of definition, a software allowing you to mobile hardware installed in your phone is also a operating system.

What is the difference between the file maintenance and file organization?
file organization is of 3 types sequential,direct and indexed sequential where how data is accessed in eash file is decided where as file maintainence is
Difference between direct sequential file and index sequential file?
Explain the difference between sequential and direct file access.A. Sequential access to data is used when the data has to be read from the start, in sequence. It is the normal method of access for magnetic tape. Direct access is used when it is possible to jump directly to a file or data item without reading through all the items stored before it. This is the normal method used for hard disks.
Is floppy disk store sequential access files?
False. It is considered as direct access storage devive
What does direct connection in file sharing mean?
Direct connection in file sharing would refer to what is more commonly knows as 'peer to peer' file sharing. This is when one individual uses a file sharing client that allows them to download directly from other (multiple) individuals and vice versa.
What is the difference between direct access and sequential access?
, Both terms "direct access" and "sequential access" as you must have guessed refer to accessing schemes in the file system. In broadest sense difference between these two can be stated like this -In sequential access data is stored at random locations. -In direct access data is stored at sequential locations. ( Ironically this is true No matter what kind of first impression we get when we hear it for the first time. ) -In sequential access addition of data is fast but retrieval of data is slow. -In direct access addition of data is slow as reordering of data blocks may be needed to put current data block after the last used data block for the file. But retrieval of data is fast. -Data structure implementing Sequential access is linked list. -Data structure implementing Direct access is an Array. Application areas:- A situation where rate of addition of data is much larger compared to retrieval of data Sequential access is preferred, in opposite situation Direct access is more suitable. Regards, Prime There are technical explanations as to how it works, but in simple terms, direct access means going straight to the record you want, whereas sequential access means going through all records one by one until you find the one you want.

Interactive mode
Describe the use of interactive websites?
Interactive websites help the visitors find or do exactly what their need is. This is done more easily than a non interactive website. This type of website could ask a person what they want to do and direct them to it.
What are advantages and disadvantages of contiguous memory allocation?
The advantage of contiguous memory allocation is 1. It supports fast sequential and direct access 2. It provides a good performance 3. the number of disk seek required is minimal The disadvantage of contiguous memory allocation is fragmentation.
What is meant by interactive system?
a system that allows direct communications between user and computer - 2 misses
