Which of the following networks extends a private network across public networks?

administrator
Which of the following networks extends a private network across public networks?
virtual private network
Explanation: A virtual private network extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.VPN provides enhanced security and online anonymity to users on the internet. It is also used to unblock websites which are unavailable in certain regions.
local area network
enterprise private network
storage area network

Network congestion occurs _________

administrator
Network congestion occurs _________
in case of traffic overloading
Explanation: Network congestion occurs when traffic in the network is more than the network could handle. To avoid network congestion, the network management uses various open-loop and closed-loop congestion control techniques.
when a system terminates
when connection between two nodes terminates
in case of transfer failure

A list of protocols used by a system, one protocol per layer, is called ________

administrator
A list of protocols used by a system, one protocol per layer, is called ________
protocol stack
Explanation: A protocol stack refers to a group of protocols that are running concurrently that are employed for the implementation of network protocol suite. Each layer in the network model has to use one specific protocol from the protocol stack.
protocol architecture
protocol suite
protocol system

A __________ is a device that forwards packets between networks by processing the routing information included in the packet.

administrator
A __________ is a device that forwards packets between networks by processing the routing information included in the packet.
router
Explanation: A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. They make use of routing protocols like RIP to find the cheapest path to the destination.
hub
firewall
bridge

Communication channel is shared by all the machines on the network in ________

administrator
Communication channel is shared by all the machines on the network in ________
broadcast network
Explanation: In a broadcast network, information is sent to all stations in a network whereas in a multicast network the data or information is sent to a group of stations in the network. In unicast network, information is sent to only one specific station. The broadcast address of the network is the last assigned address of the network.
unicast network
multicast network
anycast network

In computer network nodes are _________

administrator
In computer network nodes are _________
all of the mentioned
Explanation: In a computer network, a node can be anything that is capable of sending data or receiving data or even routing the data to its destination. Routers, Computers and Smartphones are some examples of network nodes.
the computer that originates the data
the computer that routes the data
the computer that terminates the data

Which of the following computer networks is built on the top of another network?

administrator
Which of the following computer networks is built on the top of another network?
overlay network
Explanation: An overlay network is a computer network that is built on top of another network. Some examples of an overlay network are Virtual Private Networks (VPN) and Peer-to-Peer Networks (P2P).
prime network
chief network
prior network

Two devices are in network if __________

administrator
Two devices are in network if __________
a process in one device is able to exchange information with a process in another device
Explanation: A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes. The nodes have certain processes which enable them to share a specific type of data using a distinct protocol.
a process is running on both devices
PIDs of the processes running of different devices are same
a process is active and another is inactive

When collection of various computers seems a single coherent system to its client, then it is called _________

administrator

“

When collection of various computers seems a single coherent system to its client, then it is called _________
distributed system
Explanation: A Computer network is defined as a collection of interconnected computers which uses a single technology for connection.
A distributed system is also the same as computer network but the main difference is that the whole collection of computers appears to its users as a single coherent system.
Example:- World wide web
computer network
networking system
mail system
