The Banker's algorithm is a deadlock avoidance strategy where the system checks whether a resource allocation request will leave the system in a safe state. If granting the request maintains safety, the allocation is allowed; otherwise, it's postponed until it can be safely granted. ...
to be taken simultaneously. Remember, taking multiple locks is only necessary when code needs to get exclusive access to memory protected by different locks. This analysis typically either yields a trivial lock ordering that will avoid deadlock or shows that complete deadlock avoidance is impossible...

We need a system which can act as an intermediary and manage all the processes and resources present in the system. AnOperating Systemcan be defined as aninterface between user and hardware. It is responsible for the execution of all the processes, Resource Allocation,CPUmanagement, File Manageme...
Although current operating systems have become more efficient and advanced over the years, they're still susceptible to issues. For example, a deadlock can hinder the system's ability to advance to the next task because the second process is waiting for the resource from the first one. A dea...
When FETCH FIRST 1 ROW ONLY is specified, Db2 also applies a sort avoidance preference that is associated with OPTIMIZE FOR 1 ROWS during access path selection. However, sometimes the avoiding of any sort can result in a more expensive (in total cost) access path being used. If this situati...
In daisy chaining system all the devices are connected in a serial form. The interrupt line request is common to all devices. If any device has interrupt signal in low level state then interrupt line goes to low level state and enables the interrupt input in the CPU. When there is no int...
