Two-way communication between a server process and a client process cannot be achieved witha single socket connection between that server and that client.O b. Each message in a message queue can be associated with a type, and a process that reads datafrom a message queue can specify which type of messages it would like to read.Oc.We do not normally need worry about managing concurrency when using sockets and messagequeues as this will be managed by the operating system kernel.O d. To successfully establish a socket connection between a server process and a client process, theserver needs to know the address of the socket and connect to it, whereas the client processneeds to be listening on that particular socket and accept the incoming connection request.O e.When using message queues to communicate between processes, the messages that are sentbetween processes cannot be of different lengths. In the context of interprocess communications (IPC) in Unix/Linux, which of the following are true aboutsignals, shared memory and pipes?Select one or more:O a.Virtual memory enables the allocation of shared memory for IPC.O b. If Process X needs to send the string "Hello World" to Process Y, Process X may send a signal toachieve this.Concurrent two-way communication between two processes cannot be achieved with the use of asingle pipe.O d. A process cannot have a handler function set up to handle the SIGINT signal, as the process maynot ignore this signal.e. Shared memory is fast because it is buffered by the operating system kernel.Of.Unnamed pipes can only be used to share data between related processes (e.g. parent processand its child process), whereas named pipes can be used to share data between processes thatare unrelated.

Step 1

Access Matrix is a security model of insurance state in PC framework. It is addressed as a grid. Access grid is utilized to characterize the freedoms of each interaction executing in the area concerning each item. The lines of grid address areas and segments address objects. Every cell of grid addresses set of access freedoms which are given to the cycles of area implies each entry(i, j) characterizes the arrangement of tasks that an interaction executing in space Di can conjure on object Oj.

Step 2

So the correct options are option 2nd and 4th

2nd - In a given access matrix,the owner of the file also have all other privileges.

4th - When capability lists are used, objects become domain
