Hi how are you my name is Rizwan I am a student . There is question in my mind and I want to get its solution because I try my best but yet not found its answer. Any body can help me in this case kindly tell me How interrupts are handled? Also describe that What is the difference between low level format and quick format?
Tell me How interrupts are handled
Hi,
This is an excellent skills with the pictures and diagrams and will tell you a lot about the interrupts and all its flavors, you should check this link, hope it would work for you,
Regarding your other questions
Low Level Format:
Low level format is a format that mostly used to format at least within a 10MB range disk, a very old type format but a special feature is that it correctly identifies the tracks and sectors of the hard disk drive.
QUICK FORMAT:
Quick format is related with the normal format. Quick format will format the drive quickly but it will not scan any bad sectors or other things so for time saving it’s a best approach but i suggest that use the normal one.
Tell me How interrupts are handled
Interrupts is defined as a signal attached to a computer or program within the computer that makes the operating system evaluates the next step that needs to be done in order to accomplish a specific command. A good analogy is getting a job. You have to submit an application letter. Next, you need to wait for the HR Personnel to call you for an interview. The process could end here if you fail the exam or the HR personnel might endorse you on the next process which is the job offer.
Low level formatting erases all the data on the disc while quick formatting simply erases the hard disk drive's metadata and file allocation tables.

Tell me How interrupts are handled
The possible number of interrupts is 256 (0-255). There are interrupt routine to handle the condition with each interrupt. When an interrupt occurs, the processor retrieves the interrupt routine by means of its starting address from the interrupt vector table. This table holds the starting addresses of the corresponding interrupt routines. In this table the addresses are stored by means of offset and segment addresses.
The length of these addresses is 2 bytes (16 bits). So each entry in the table is actually 4 bytes long. Therefore the total length of the interrupt vector table is 256X4 or 1024 bytes or 1Kbytes.
When any low level formatting is performed, the control information like track and sector numbers is set. Also the control structure which determines the location of tracks and sectors is rewritten. But in quick formatting only the file system structure is written, i.e it is the process of setting up an empty file system such as the boot block, NTFS, FAT etc.
