Q. Error detection in operating system?
Error detection- Error detection take places at both the hardware and software levels. At the hardware level every data transfers must be inspected to ensure that data haven't been corrupted in transit.
All data on media should be checked to be sure they have not changed since they were written to the media. At the software level media should be checked for data consistency for instance whether the number of allocated and unallocated blocks of storage matches the total number on the device. There errors are habitually process-independent (for instance the corruption of data on a disk) therefore there must be a global program (the operating system) that handles all types of errors. As well by having errors processed through the operating system processes need not contain code to catch and correct all the errors possible on a system.

List operations to be performed on directories. Search for a file, delete a file, create a file, list a directory, rename a file, and traverse the file system.
Garbage collectors trade space for time. If we collect all the time (which requires a lot of processing time), the GC allocator will use the least memory possible. On the other han
