Answer:
It happens to me as well. Maybe check emails? It could also be a bug.
Explanation:
An individual who possesses good work ethic embodies principles like reliability, dependability, dedication to the job, teamwork and cooperation, and a self-disciplined character. Most employers seek a strong work ethic; performance depends on it; satisfaction is derived from it; and it ensures career progression. It is that untouchable effort an employee exemplifies daily, regardless of whether someone is watching or not. A company that has its employees doing exemplary well has everything to do with their performance. Thus, if you have a strong work ethic, you will have qualities that will keep you in demand by huge companies. When you are skilled at the workplace and your colleagues notice and appreciate it, you will have a very deep sense of satisfaction within you. If you put 101 percent, your willingness to work hard will be recognized and will leave you shining brightly than others when the opportunity of promotion knocks.
The allocation methods define how the files are stored in the disk blocks.
There are three main disk space or file allocation methods:
1.Contiguous Allocation-in this scheme,each file occupies a set of blocks on the disk. For example if a file requires x blocks and is given a block y as the starting location,then the blocks assigned to the file be :x,y+1,y+2,......y+x-1.
This means that given the starting block address and the length of the file(in terms of blocks required) we can determine the blocks occupied by the file.
Advantages
-both the sequential and direct accesses are supported
-this is extremely fast since the number of seeks are minimal because of contiguous allocation of file blocks.
2.linked allocation-in this scheme,each file linked list of disk blocks which need not be contiguous disk blocks can be scattered anywhere on the disk.
Advantages
it is very flexible in terms of file size.file size can be increased easily since the system does not have to look for a contiguous chunk
of memory.
this method does not suffer from external fragmentation and it makes it relatively better in terms of memory utilization.
3.Indexed Allocation-in this scheme,a special block known as the index block contains the pointers to all the blocks occupied by a file.Each file has its own index block.the entry in the index block contains the disk address of the block
Advantages
it supports direct access to the blocks occupied by the file and therefore provides fast access to the file blocks
it overcomes the problem of external fragmentation.
