Network congestion is occurred due to accessing of same bandwidth by many users at the same time and there is no alternative to network segmentation. Ques 4: What is routing? Routing is process of finding the shortest path for communicating from source to destination. This process is accomplished by the routers on network. Ques 5: What is window in networking terms? A window is sets of segment that is allowed to be sent from source to destination before the acknowledgement is sent back to it.
Ques 7: What is sub-Netting? Why it is used? It is used to break the larger network into smaller sub-networks, used in IP Networks. Basically used for minimizing the network traffic, optimizing the performance, and managing the network. Ques 8: What is communication and how it is differ to transmission?
Communication means exchanging of data between source and destination. Whereas, transmission refers to only transferring of data from source to receiver. Ques 9: Two interface of the router is configured with IP addresses Would the routing table of the router contain any information? Provide explanations Ans. The router would have to perform AND operation with IP address and subnet mask when the interface has configured. This is ultimately yield a network address and after it configured to interface, two entries will available in the routing tables which are Ques Does bridge divide a network into smaller segments?
No, it not, it only filters the large networks without changing their size.
Ques What is the role of LLC sub layer? Logical Link Control sub layer provides the controlled or optional services to the Network layer with start and stop codes. It also does the error correction. A method to standardize and categorize fault tolerance disk systems. Ques List the two types of transmission technology? Point-to-point and broadcast transmission technologies are available in the CCNA.
Ques What is point-to-point transmission protocol? Although both are the communication devices and both are used to transmit and receive data but full-duplex facilitate you to transmit and receive data at the same time while half-duplex cannot receive while it is transmitting data.
What Does Mtu Stand For? MTU determines the maximum size of a packet that is sent across the network.
You can increase MTUs across the network, but this setting generally slows down the network compared to smaller MTU settings. Broadcast domain is a domain where if a broadcast frame is forwarded, every device pays attention and receives the data.
While in Collision domain, chances of data collision is maximum. Like in Hub, if two or more send traffic at the same time, data will collide in between and none of the devices will receive the data. It should include subnet mask of each destination address. What Is Subnet? Why Is It Used? Subnets are used in IP network to break up larger network into smaller network. It is used to optimize the performance of network because it reduces traffic by breaking the larger network into smaller networks.
It is also used to identify and isolate network's problem and simplify them. What Is Network Latency?
Network latency refers to the performance of one device when it communicates with another. Network latency is affected by bandwidth speeds, network card performance, cabling and congestion.
What Is Poe power Over Ethernet? POE allows electrical current to be carried by the cable rather than the power cords. It minimizes the number of wires required to install the network. There are five types of passwords can be set on a Cisco router: It is a media access control method used in local area networking using early Ethernet technology to overcome the occurred collision. It is used in wireless network to avoid collision.
These two modes are somewhat self-explanatory. The user mode allows the user to view router status and basic system information.
With privileged mode access status, the router can be configured and all status messages and errors can be viewed. IPv4 is a 32 bits address and IPv6 is bits address. ARP is a protocol that is used to map an IP address to a physical machine address. Straight cable: Straight cable is used to connect different group devices. For example: Switch- Router. Cross cable: Cross cable is used to connect same group devices. When you send traffic on a network, the router default gateway in Windows computer terminology determines how to route the traffic.
Each router is considered a hop. With IGRP, several more factors are considered. What Is Checksum? A checksum is a count of the number of bits in a transmission data that is included with the data so that the receiver can check to see whether the same number of bits arrived. These are the three possible ways of data transmission: These are the two major types of networks: What Are Data Packets?
Data packets are the encapsulation units that transmit information across a network. It also contains the numeric identification number that defines the order and packet number.
When you send data across the network, that information is segmented into data packets. The recipient then puts these packets together to be able to read the information.
The router is a networking gateway device that is used to forward data packets to the computer networks. A router supports two broadcast domains. In the hub, if anything comes in its port then it sends it out to the others. It is less expensive and least complicated. It has a single collision domain and a single broadcast domain. There are two types of network:. It is stored in ROM and is uniquely defined.
It is identified as the Media Access Control layer in the network architecture. Broadcast Domain In the Broadcast Domain, all the juncture can reach each other by broadcast at the data link layer and every device is ready to receive their respective data.
Broadcast Domain uses local network for broadcasting the data packets to the receiver. While broadcasting, massive data are broadcasted, hence the speed of receiving the data is less and it also takes more time to receive the data of their address. Collision Domain In the Collision Domain, data collision occurs more due to sending of more frames simultaneously.
If more than two frames are sent simultaneously then the data will collide with each other in between and the information gets lost due to an occurrence of a collision and the devices will not accept the data and due to this, the communication between the sender and receiver side will collide.
