Answer:
A. Request timeout.
Explanation:
The end devices like the computer systems in a network seeks to share resources with one another and/ or request resources from central server.
With this, there are two ways computers in a network can communicate. They are peer to peer network communication and client-server network communication.
The client-server communication requires a dedicated central server where computers in the network require data. Peer to peer describes a network where computers serve as both client and server to each other.
Request timeout is a message sent to a source when the time to live period (TTL) of a packet expires.
Answer: Decoupling action of the process address space refers to the physical memory of the device getting decoupled to provide address translation in automatic way. The benefit of this method is as follows:-
- Faster starting up of the program
- The physical address space gets managed on its own
- Helps in execution of large program when the main memory of the machine is of smaller size in comparison with program
<u>Output:</u>
f1 in A
f2 in A
f1 in B
f2 in A
f1 in A
f2 in A
f1 in B
f2 in B
<u>Explanation:</u>
In this snippet, the code makes use of virtual functions. A virtual function is defined as a function that is defined in the base class and redefined in the derived class. If the derived function accesses the virtual function, the program will get executed with the derived class’s version of the function.
In this code, we define the virtual function f1() in class A and also redefine it in class B which is the derived class of A. While executing the program, the function g which takes the object b (class B’s object) as a parameter. It will print class B’s version of f1() rather than class A’s version. This is working off the virtual function.
Complete Question:
A local area network is:
Answer:
b. a group of personal computers or terminals located in the same general area and connected by a common cable (communication circuit) so they can exchange information such as a set of rooms, a single building, or a set of well-connected buildings.
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings.
Generally, some of the network devices or equipments used in a local area network (LAN) are an access point, personal computers, a switch, a router, printer, etc.
