Technical Questions

Distributed systems work in a network. They can share the network resources,communicate with each other.

1. Mutual exclusion (where at least one resource is non-sharable)

2. Hold and wait (where a process holds one resource and waits for other resource)

3. No preemption (where the resources can’t be preempted)

4. Circular wait (where p[i] is waiting for p[j] to release a resource. i= 1,2,…n

j=if (i!=n) then i+1

else 1 )

Interior gateways connect LANs of one organization, whereas exterior gateways connect the organization to the outside world.

Floating gate avalanche injection MOS (FAMOS) transistor is used in each cell of EPROM.

Configuration Management is a support for software in managing the different items in the product, and changes in them.

In microprocessor more op-codes, few bit handling instrucitons. But in Microcontroller. fewer op-codes, more bit handling Instruction, and also it is defined as a device that includes micro processor, memory, & input / output signal lines on a single chip.

the basic architectual difference is that microcontroller has an programmable memory while it is not the case with mivroprocessors.

It is the transfer of sufficient amount of the state of process from one machine to the target machine.

Hardware device that maps virtual to physical address. In MMU scheme, the value in the relocation register is added to every address generated by a user process at the time it is sent to memory.

->The user program deals with logical addresses; it never sees the real physical addresses
