What do you know about file allocation in OS?

The file allocation methods in OS are various ways to store the file on the hard disk. Well, there are various ways to store the files on the hard disk, which means there is an efficient utilization of disk space, and then the file can be accessed faster by the OS. The operating system stores data in memory blocks thru various kinds of file allocation methods that will allow the hard disk in order to be used efficiently and the file to be accessed. Each file is stored in such disk blocks, even if it may not be possible to store a file in a single or the same disk.

File allocation methods are needed in order to allocate memory to the files judiciously. There may also ensure that access and modification to the files are highly possible in the shortest time possible. The file allocation in OS means while the hard drive is formatted and a system has various small spaces in order to store the files is, called blocks. Well, the OS stores data in the memory blocks by using diverse file allocation methods that allow the hard disk to be utilized efficiently and the file to be accessed.

The contiguous allocation method, linked allocation method, and indexed allocation method are in space allocation which of the following ways. Each of the methods is unique from the others and gives effective services for storing the data in OS. With the aid of the allocation method, you may utilize the disk, and files are easily accessed. 

• The contagious file allocation is known to be file allocated in their manner. 
• In the linked file allocation, the pointers are utilized to point to the next block of the same file. 
• The indexed file allocation is similar to the linked file allocation. All the pointers are put together into one location that is known by the indexed book. 

In space allocation which of the following ways: What is the mounting of the file system?

Mounting a file system attaches a file system to a directory and then makes it available to the system. Well, the root file system is always mounted, and any other file system is easily connected or disconnected from the root file system. It is attaching a portion of the file system into a directory structure. The mount command will attach a file system or storage device, making it possible to an existing directory structure. Finally, the umount command will tell the system in order to finish any outstanding read or write functionality prior to removing a moue to the file system securely and safely. 

In space allocation which of the following ways: Select the correct statement about the indexed allocation

The indexed allocation method is one of the methods that is used for file allocation. In this allocation method, there may have an additional block, and that is known as an indexed block. Well, for each file, there is an individual index block that includes an ith entry that holds the disk address of the ith file block. It may have various advantages; this method will solve the external fragmentation and then give direct access—indexed allocation in space allocation which of the following ways. The blocks and pointer were spread over the memory in the linked allocation method, and so the retrieval was accomplished by visiting all blocks considerably. Well, it becomes easiest with the indexed block in order to retrieve. 

Conclusion

Now you may get more ideas regards the file allocation in OS, and the process is completed most efficiently. In order to store the data in the OS, you may choose any one of the allocation methods. 

FAQs about In space allocation which of the following ways:

What type of allocation method is each file?

The foremost things behind the allocation method are effective utilization of the file space and fast access to the files. The file allocation methods are considerable ways that any file may store in the memory block of the system. There are three types of allocation methods Contagious, linked and indexed allocation methods. 

In which method the file allocation table contains?

It will overcome the drawback of the linked file allocation. Random access to the specific block is not highly possible in the linked file allocation. In order to access the particular block, there is necessary to access all previous blocks.
