Differentiate between mutexes vs semaphores.
Semaphores is a synchronization tool to overcome the critical section problem.
A semaphore S is Basically an integer variable that apart from initialisation is accesses only through atomic operations such as wait() and signal().
Semaphore object basically acts as a counter to monitor the number of threads accessing a resource.
Mutex is also a tool that is used to provide deadlock free mutual exclusion.It protects access to every
critical data item.if the data is locked and is in use,it either waits for the thread to finish or awakened to
release the lock from its inactive state.
What are the commonly found errors in Embedded Systems?
Damage of Memory devices due to transient current and static discharges.
Malfunctioning of address lines due to a short in the circuit
Malfunctioning of Data lines.
Some memory locations being inaccessible in storage due to garbage or errors.
Improper insertion of Memory Devices into the memory slots
Faulty control signals.
