B. configuring the hardware Mesh Topology uses Routing and Flooding techniques for data transmission. And then the hub sends the same data to the destination device. Generally, we assign names to websites and computers like Gmail.com, Hotmail, etc. It completely removes the process of manual allocation of IP addresses and reduces the errors caused due to this. For Example, if we connect a computer and laptop to a printer, then we can call it as an Ethernet network. It offers online data storage, infrastructure, and application. A. OSI model has seven layers. Answer: Network Topology is nothing but the physical or logical way in which the devices (like nodes, links, and computers) of a network are arranged. The compilation of all the quizzes (mcq) for each and every chapters in the book of Data Communications and Networking by Behrouz A. Forouzan. ________________ is yet another service model, which includes Network-as-a-Service, Business-as-a-Service, Identity-as-a-Service, Database-as-a-Service or Strategy-as-a-Service. IP class belongs to Class C if the octet starts with bits 110. A firewall can also be built to grant limited access to outside users. Multiple Choice Questions of Computer Networking 1-1 Computer Network is A. If user has account on that computer then only user able to access the computer, If user has an account in a domain then user can login to any computer in a domain, Workgroup does not bind to any security permission or does not require any password, Domain user has to provide security credentials whenever they are accessing the domain network, Computer settings need to change manually for each computer in a Workgroup, In a domain, changes made in one computer automatically made same changes to all other computers in a network, All computers must be on same local area network, In a domain, computers can be on a different local network, In a Workgroup, there can be only 20 computers connected, In a domain, thousands of computers can be connected. This variable-length data sequence is also known as “Datagrams”. Now scan the secondary HDD and clean it. In bi-directional communication, the HTTPs protocol encrypts the communication so that the tampering of the data gets avoided. A firewall examines each message and blocks the same which are unsecured. The advantage of mesh topology is if one link breaks then it does not affect the whole network. TCP is a connection oriented protocol, UDP is connectionless, simple protocol. Using UDP, messages are sent as packets, TCP is used for the application where time is not critical part of data transmission. Q #27) Describe the layers of the OSI model?

Answer: Network is defined as a set of devices connected … e) Session Layer (Layer 5): This layer manages and controls the connections between computers. VPNs are used to connect offices remotely and are less expensive when compared to WAN connections. Translating the names into numbers or IP address is named as a Forward lookup. Q #15) What is a Proxy Server and how do they protect the computer network? This layer also detects the errors that occurred at Layer 1. c) Network Layer (Layer 3): This layer transfers variable length data sequence from one node to another node in the same network. If a device in the network is facing any problem, then it notifies the other devices that they are not receiving any signal. Then connect the HDD of the infected system as a secondary drive. Routers are similar like little computers dedicated for routing network traffic, In a Network, Hub is a common connection point for devices connected to the network.

Here you will find a list of common important questions on basic computer knowledge in MCQ quiz style with answer for competitive exams and interviews. Ifconfig (Interface Configuration) is a command that is used on Linux, Mac, and UNIX operating systems. It is in the form of an add-in card and is installed on a computer so that the computer can be connected to a network. For Example, When you type a website www.softwaretestinghelp.com, then your Internet service provider looks for the DNS associated with this domain name and translates this website command into a machine language – IP address – 151.144.210.59 (note that, this is the imaginary IP address and not the actual IP for the given website) so that you will get redirected to the appropriate destination. Both protocols TCP and UDP are used to send bits of data over the Internet, which is also known as ‘packets’. Answer: In a computer network, to enable data transmission from one computer to another, the network devices send messages in the form of packets. > Dear reader, if you are looking for important multiple choice questions with answer from computer Network, then you are in right place. B. Answer: In data transmission, if the sender sends any data frame to the receiver then the receiver should send the acknowledgment to the sender. If IP classes support more networks then very few IP addresses are available for each network. Explanation: Cloud computing offers platform independency, as the software is not required to be installed locally on the PC. Answer: Open System Interconnection, the name itself suggests that it is a reference model that defines how applications can communicate with each other over a networking system. Dynamic IP is the temporary IP address assigned by the network to a computing device. Answer: There are 4 major types of networks. And a break at a node in the network can affect the whole network. B. Platform-as-a-Service It prevents malicious access from outside to the computer network. HTML MCQ Question with Answer.
