Question 1. Question 2.
What are the important topologies for networks? BUS topology: In this each computer is directly connected to primary network cable in a single line. Inexpensive, easy to install, simple to understand, easy to extend.
STAR topology: In this all computers are connected using a central hub. Can be inexpensive, easy to install and reconfigure and easy to trouble shoot physical problems. RING topology: In this all computers are connected in loop. All computers have equal access to network media, installation can be simple, and signal does not degrade as much as in other topologies because each computer regenerates it. What is mesh network? A network in which there are multiple network links between computers to provide multiple paths for data to travel.
What is difference between baseband and broadband transmission? In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously. What is packet filter? Packet filter is a standard router equipped with some extra functionality. The extra functionality allows every incoming or outgoing packet to be inspected. Packets meeting some criterion are forwarded normally.
Those that fail the test are dropped. What is traffic shaping? One of the main causes of congestion is that traffic is often busy. If hosts could be made to transmit at a uniform rate, congestion would be less common. Another open loop method to help manage congestion is forcing the packet to be transmitted at a more predictable rate.
This is called traffic shaping. What is multicast routing?
Sending a message to a group is called multicasting, and its routing algorithm is called multicast routing. What is Kerberos? It is an authentication service developed at the Massachusetts Institute of Technology.
Kerberos uses encryption to prevent intruders from discovering passwords and gaining unauthorized access to files. What is passive topology? Example for passive topology - linear bus. What are the advantages of Distributed Processing? Distributed database c. Faster Problem solving d.
Security through redundancy e. Collaborative Processing. Name the factors that affect the reliability of the network? Frequency of failure b. Recovery time of a network after a failure. When a switch is said to be congested? It is possible that a switch receives packets faster than the shared link can accommodate and stores in its memory, for an extended period of time, then the switch will eventually run out of buffer space, and some packets will have to be dropped and in this state is said to congested state.

You can even call it as the line configuration. Click on Whatapp logo to join oureducation banking group with many students 2 Write the types of networks. It happens within a secure ,password protected network.
Cellular technology — uses antennae resembling telephone towers to pick up radio signals within a specific area 4 What is network typologies?
Bus topology — all computers are synchronize by a single line of cable. Star topology — multiple computers are linked to a main computer, which is called a host Ring topology — each computer is connected to two other computers, with the entire network. Radio signal, the print signal given from computer to printer etc.
Data transferring can happen in both directions but not at the same time. Alternatively, the data is sent and received. Browsing through the internet, a user sends the request to the server and later the server processes the request and sends back the web page.
Data transferring happens in both directions that too simultaneously. Two lane road where traffic flows in both the directions, communication through telephone etc. Q 33 Name the different types of network topologies and brief its advantages? Ans Network Topology is nothing but the physical or logical way in which the devices like nodes, links, and computers of a network are arranged. Physical Topology means the actual place where the elements of a network are located.
Logical Topology deals with the flow of data over the networks. A Link is used to connect more than two devices of a network. And more than two links located nearby forms a topology. The network topologies are classified as mentioned below. As the devices are connected to a single cable, it is also termed as Linear Bus Topology. The advantage of bus topology is that it can be installed easily.
And the disadvantage is that if the backbone cable breaks then the whole network will be down. In Star Topology, there is a central controller or hub to which every node or device is connected through a cable.
In this topology, the devices are not linked to each other. If a device needs to communicate with the other, then it has to send the signal or data to the central hub. And then the hub sends the same data to the destination device. The advantage of the star topology is that if a link breaks then only that particular link is affected.
The whole network remains undisturbed. The main disadvantage of the star topology is that all the devices of the network are dependent on a single point hub.
If the central hub gets failed, then the whole network gets down. Data or Signal in ring topology flow only in a single direction from one device to another and reaches the destination node. The advantage of ring topology is that it can be installed easily. Adding or deleting devices to the network is also easy.
The main disadvantage of ring topology is the data flows only in one direction. And a break at a node in the network can affect the whole network.
In a Mesh Topology, each device of the network is connected to all other devices of the network. Mesh Topology uses Routing and Flooding techniques for data transmission. The advantage of mesh topology is if one link breaks then it does not affect the whole network. And the disadvantage is, huge cabling is required and it is expensive. Ans In data transmission if the sender sends any data frame to the receiver then the receiver should send the acknowledgment to the sender.
The receiver will temporarily delay waits for the network layer to send the next data packet the acknowledgment and hooks it to the next outgoing data frame, this process is called as Piggybacking. Q 36 In how many ways the data is represented and what are they?
Q 38 How a Switch is different from a Hub? Ans The time taken for a signal to reach the destination and travel back to the sender with the acknowledgment is termed as Round Trip time RTT. Ans Brouter or Bridge Router is a device which acts as both bridge and a router.
As a bridge, it forwards data between the networks. And as a router, it routes the data to specified systems within a network. It is assigned by the Internet Service Provider as a permanent address. Dynamic IP is the temporary IP address assigned by the network to a computing device. Dynamic IP is automatically assigned by the server to the network device.
Q 42 How VPN is used in the corporate world? Corporate companies, educational institutions, government offices etc use this VPN. Q 43 What is the difference between Firewall and Antivirus? Ans Firewall and Antivirus are two different security applications used in networking. A firewall acts as a gatekeeper which prevents unauthorized users to access the private networks as intranets.
A firewall examines each message and blocks the same which are unsecured. Antivirus is a software program that protects a computer from any malicious software, any virus, spyware, adware etc. A Firewall cannot protect the system from virus, spyware, adware etc.
Ans If a network self-repair its problem then it is termed as Beaconing. If a device in the network is facing any problem, then it notifies the other devices that they are not receiving any signal. Likewise, the problem gets repaired within the network.
Q 45 Why the standard of an OSI model is termed as Ans OSI model was started in the month of February in So it is standardized as When a new device is added to the network, it broadcasts a message stating that it is new to the network. Then the message is transmitted to all the devices of the network. Q 47 How can a network be certified as an effective network? What are the factors affecting them? Ans A network can be certified as an effective network based on below-mentioned points,.
DNS acts as a translator between domain names and IP address. As humans remember names, the computer understands only numbers. Generally, we assign names to websites and computers like gmail.
When we type such names the DNS translates it into numbers and execute our requests. This is used to design or develop standards that are used for networking. Q 50 What is the use of encryption and decryption? Ans Encryption is the process of converting the transmission data into another form that is not read by any other device other than the intended receiver.
Decryption is the process of converting back the encrypted data to its normal form. An algorithm called cipher is used in this conversion process. For example, if we connect a computer and laptop to a printer, then we can call it as an Ethernet network.
Ethernet acts as the carrier for internet within short distance networks like a network in a building. The main difference between Internet and Ethernet is security. Ethernet is safer than the internet as Ethernet is a closed loop and has only limited access.
Ans Encapsulation means adding one thing on top of the other thing. When a message or a packet is passed through the communication network OSI layers , every layer adds its header information to the actual packet. This process is termed as Data Encapsulation.
Decapsulation is exactly the opposite of encapsulation. The process of removing the headers added by the OSI layers from the actual packet is termed as Decapsulation. Q 53 How are networks classified based on their connections? Ans Networks are classified into two categories based on their connection types. They are mentioned below,.
Ans In Networking when a task is in progress another task gets started before the previous task is finished. This is termed as Pipelining.
