- Q1. Question on projects.
- Q2. How packet goes from source to destination.
- Ans.
Packets are sent from source to destination through a series of network devices using routing protocols.
Packet is created at the source with source and destination IP addresses.
Packet is sent to the default gateway or router.
Router checks its routing table to determine the next hop for the packet.
Packet is forwarded to the next hop until it reaches the destination.
Destination receives the packet and sends an acknowledg
- Q3. Delete a node from single linked list.
- Ans.
To delete a node from a single linked list, we need to find the node and update the pointers.
Traverse the list to find the node to be deleted
Update the previous node's pointer to point to the next node
Free the memory of the node to be deleted
- Q4. Dynamic memory alocation in c
- Ans.
Dynamic memory allocation in C allows allocation of memory at runtime.
Dynamic memory allocation is done using functions like malloc(), calloc(), realloc() and free().
malloc() allocates memory block of specified size and returns a pointer to the first byte of allocated memory.
calloc() allocates memory block of specified size and initializes all bits to zero.
realloc() changes the size of previously allocated memory block...
- Q5. Interprocess communication in OS
- Ans.
Interprocess communication is a mechanism that allows processes to communicate with each other in an OS.
IPC mechanisms include pipes, sockets, message queues, shared memory, and signals.
IPC can be used for synchronization, data sharing, and coordination between processes.
IPC can be implemented using system calls such as fork(), pipe(), socket(), and msgget().

- Q1. 1.explain what is a watchdog timer
- Ans.
A watchdog timer is a hardware or software component that monitors the operation of a system and resets it if necessary.
A watchdog timer is used to prevent system crashes or lock-ups by resetting the system if it becomes unresponsive.
It is typically implemented as a counter that needs to be periodically reset by the system software.
If the watchdog timer is not reset within a certain time period, it triggers a system re...
- Q2. 2.explain what is semaphore
- Ans.
Semaphore is a synchronization object used to control access to a shared resource.
Semaphore is a signaling mechanism used to control access to a shared resource
It allows multiple processes/threads to access the shared resource simultaneously
Semaphore maintains a count of the number of resources available
When a process/thread requests access to the resource, the count is decremented
When the process/thread releases the r...
- Q3. What is a interrupt latency
- Ans.
Interrupt latency is the time delay between the occurrence of an interrupt and the start of the routine that services the interrupt.
Interrupt latency is a critical factor in real-time systems
It can be affected by factors such as the priority of the interrupt and the current state of the processor
Reducing interrupt latency can improve system performance and responsiveness
Examples of interrupts include hardware interrupt...
- Q4. What does DMA address will deal with
- Ans.
DMA address deals with data transfer between memory and peripherals without CPU intervention.
DMA stands for Direct Memory Access.
DMA address is used to transfer data between memory and peripherals without CPU intervention.
