Write a short note on peer-to-peer computing.
Peer-to-peer (P2P) system model is a kind of distributed OS. In this model, clients and servers aren't distinguished from one another. in its place, all nodes inside the system are considered peers, and each may proceed as either a client or a server, depending on whether it is providing or requesting a service. Peer-to-peer systems offer a benefit over traditional client server systems; several nodes distributed during the network can provide services.
To participate in a peer-to-peer system a node has to first join the network of peers. Formerly a node has joined the network, it able to begin providing the services to and requesting services from - other nodes in the network. Determining what services are available is proficient in one of two general ways:
* When a node connects a network it registers its service with a centralized lookup service on the network. Any node wants a specific service first contacts this centralized lookup service to determine which node provides the service. The remainder of the communication takes among the client and the service provider.
** A peer acting like a client must first discover what node provides a desired service by broadcasting a request for the service to all other nodes in the network. The node (or nodes) offers that service responds to the peer making the request. To favor this approach, a discovery protocol should be provided that allows peers to discover services provided by other peers in the network.
What are the different thread levels? There are two broad type of thread implementation: User-Level Threads -- Thread Libraries. Kernel-level Threads -- System Calls.
Write a C program that illustrates the creation of child process using fork system call. One process finds sum of even series and other process finds sum of odd series.
Q. What is the use of system programs? Answer: System programs are able to be thought of as bundles of useful system calls. They provide fundamental functionality to users so
Q. Consider a file at present consisting of 100 blocks. Presume that the file control block (and the index block in the case of indexed allocation) is already in memory. Compute h

Q. Presume that we agree that 1 kilobyte is 1,024 bytes 1 megabyte is 1,0242 bytes and 1 gigabyte is 1,0243 bytes. This progression carries on through terabytes, petabytes, and ex
How can the deadlock be prevented-Safe State Safe state : A state is safe if the system is able to allocate resources to each process in some order and still avoid deadlock.
Allocators can also be used to avoid problems with unsafe languages. C and C++ are pervasive, with huge amounts of existing code. They are also memory-unsafe languages, in that the
Q. Consider a calculating environment where a unique number is associated with each process and each object in the system. Suppose that we permit a process with number n to acce
