Practice Best Networking Interview Questions;

Q1. What Is the WWW?

The term WWW stands for World Wide Web also known as W3 which is basically a collection of web pages found on the network of computers. It was invented by Tim Berners-Lee. It is one of the applications built on top of the Internet which is a network of online content that is formatted in HTML and accessed via HTTP.

Q2. Where do we use cross and standard cable?

A Crossover cable is used to connect two or more computing devices. It is made to connect to network devices of the same kind over Ethernet directly. Crossover cables are mostly used to connect two hosts directly. Whereas a Standard cable is also known as a Straight-through cable which is used in LAN to connect a computer or a network hub such as a router. It is one of the most common types of network cable.

Q3. What Is an URL?

URL stands for Uniform Resource Locator which is a specific type of Uniform Resource Identifier that is used to specify addresses on the World Wide Web. It is consists of the domain name, along with other detailed information, to create a complete web address to identify the specific web page deployed over the internet. For example -

Q4. What is Protocol?

A Protocol is basically an established set of rules that is used to determine how data is transmitted between different devices within the same network. A network protocol helps the devices to exchange information and communicate with each other, regardless of any differences in their internal processes, structure, or design. Some of the different types of protocols are Post office Protocol (POP) Simple mail transport Protocol (SMTP) File Transfer Protocol (FTP) Hyper Text Transfer Protocol (HTTP).

Q5. How many pins do serial ports have?

The number of pins that serial ports have varies with respect to the version of the serial ports. That means If you are using an old serial port then it will consist of 25 pins but among these 25 pins, only 9 pins were used. Whereas if you are using the latest version of the serial port then it will consist of only 9 pins.

Q6. What is a gateway or Router?

A gateway is also known as a node or router is a key stopping point for data on its way to or from other networks. It acts as a network entity that allows a network to interface with another network with different protocols in order to join dissimilar systems. It can take several forms and perform a variety of tasks which include Web application firewalls etc.

Q7. Define 802.11 Wireless LAN and CSMA?

802.11 wireless LANs use a media access control protocol called Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). The CSMA/CA stands for Carrier Sense Multiple Access/Collision Avoidance which is a protocol for carrier transmission in 802.11 networks. CSMA is a media access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus or a band of the electromagnetic spectrum.

Q8. What is TCP/IP?

TCP/IP stands for Transmission Control Protocol/Internet Protocol model which is a communications architecture used for networking computers and to communicate across the Internet. It is a two-layered program that defines how the data between the devices should transmit and thus enables communication over networks and large distances.

Q9. What is FDDI?

FDDI stands for Fiber Distributed Data Interface which is a set of ANSI and ISO standards for data transmission on fiber-optic lines in a local area network (LAN). It is a standard for data transmission in a local area network which is used on the backbone for a wide area network (WAN).

Q10. What is the full form of ping?

PING stands for the Packet InterNet Groper which is a computer network management system software also known as utility software. Ping is used to testing the network communication between the two devices.

Q11. What is the difference between Cells and Packets?

The difference between Cells and Packets can be stated a packet is a small segment of a larger message that includes information such as the source and destination, the protocols, or identifications. Whereas a cell is a geographical area covered by the frequency emitted by a base station in a cellular network.
