1. What Exactly is RIP?
In answer, RIP is an abbreviation for Routing Information Protocol, which is sometimes referred to as Interior Gateway Protocol (IGP). When determining the best acceptable route between a sender and a receiver, it is a distance-vector protocol that employs hop count as a routing measure.
2. The Distinction Between A Collision Domain And Broadcast Domain Is Explained In Detail.
When two devices attempt to transfer data at the same time, a collision will occur, causing them to pause and re-transmit the data. Answer: Collision domain as a result, when two devices in a network communicate information, the collision domain must consider all of the devices connected to the network, regardless of whether the information is intended for them. It only occurs in the event of a half-duplex mode of operation.
3. What Exactly Are The Differences Between Half-Duplex And Full-Duplex Transmission Modes?
Half-duplex is the answer. Using a network cable, two devices are joined together in a point-to-point system, and these devices may communicate with each other in both ways at the same time, rather than just in one direction.
A point-to-point system in which two devices are linked by a network cable, and in which these devices may communicate with each other in both directions at the same time is known as full-duplex communication.
4. Explain The Difference Between Public and Private IP Addressing.
Answer: A public IP address is an IP address that can be accessed over the Internet, such as a web server or an email server. The public IP address assigned to your computer enables you to protect your own server, which may be used for VPN, FTP, WEB, and other services. You may set up any home server to publish content on the Internet with the use of a public IP address by Sprintzeal.
It is the IP address of a system that is used to connect with other systems on the same network that has been designated as its private IP address. Private IP addresses are not placed into the Internet, and no data may be transferred to them from the Internet; they only function inside the confines of the local network.
5. What Exactly Is The Difference Between Unicast, Multicast, Broadcast, And Anycast Communication Protocols?
Answer: A single data packet is transmitted from the source to a single destination on the network when using a unicast transmission.
A single data packet is transmitted to all of the destinations on the network when broadcasting is used.
Multicast is similar to broadcast, except that to participate in multicast, you must be a member of the multicast group.
Anycast is a network communication technique in which data is transmitted to the nearest node in the network, and that node subsequently launches another anycast to the next closest node.
6. What’s the Difference Between Straight-Through And Crossover Cables And How Do They Work?
Straight-through: This form of connection is useful when you need to connect two distinct types of devices together. It is the most widely used cable standard for network cables and is also the most expensive. It aids in the connection of a router’s WAN port to a LAN port on a computer.
In order to connect two devices of the same kind, you may use a crossover cable. It is exclusively used in a few particular situations. Using the standard port on both hubs or switches, you may establish a connection between two hubs or switches.
7. Explain What NOS Stands for.
When it comes to operating systems, a NOS (Network Operating System) is a kind of operating system that handles network resources, similar to an operating system that has additional features for integrating computers and devices into a local area network. For instance, Windows Server 2019, Linux Server, and so on.
