Both Routers and Modems are network connecting devices. Routers work at the network layer and are responsible to find the shortest path for a packet, whereas Modems connect a device like desktop, laptop to the Internet. Routers connect devices across multiple networks. Read through this article to find out more about Routers and Modems and how they are different from each other. What is a Modem? A modulator-demodulator, or a modem, is a piece of hardware that transforms data from a digital format designed for direct communication between devices using specific cabling into a format suitable for transmission via ...

Both Routers and Bridges are network connecting devices. Routers work at the network layer and are responsible to find the shortest path for a packet, whereas Bridges connect various devices in a network. Routers connect devices across multiple networks. Read through this article to find out more about routers and bridges and how they are different from each other. What is a Router? A router is a networking device that receives, processes, and sends data packets from one computer network to another. On the Internet, routers are in charge of traffic steering. Data packets are used to send data across ... Read More

Both Routers and Switches are network connecting devices. Routers work at the network layer and are responsible to find the shortest path for a packet across the network, whereas Switches connect various devices in a network. Routers connect devices across multiple networks. Read through this article to find out more about these two network devices and how they operate to understand how they are different from each other. What is a Router? Routers are network connecting devices that determine the shortest path for a packet to take to get to its destination. A router's primary function is to connect ... Read More

Stop and Wait protocol is a protocol for flow control mechanism. In this protocol, the sender sends one frame at a time and waits for acknowledgment from the receiver. Once acknowledged, the sender sends another frame to the receiver. Stop and Wait protocol is also a protocol for flow control mechanism. In this protocol, the sender sends multiple frames at a time and retransmits the frames which are found to be corrupted or damaged. Read through this article to find out more about these two protocols and how they are different from each other. What is Stop and Wait ... Read More

The process of turning plain text into an encrypted form (cipher text) is known as encryption. Sensitive data is transmitted in an encrypted form so that it can be protected and a strong encryption mechanism ensures that the data is not misused even if a hacker gets hold of it. Decryption is the reverse mechanism where the encrypted cipher text is converted back into its original form.Read through this article to find out more about encryption and decryption and how they are different from each other.What is Encryption?Encryption is the procedure of encoding data in cryptography. This procedure turns plaintext, ... Read More

What is an IP Address? An IP address (Internet Protocol address) is a numerical identifier, such as 192.0.2.1, that is associated with a computer network that communicates using the Internet Protocol. An IP address is used for two purposes: identifying a host or network interface, and addressing a specific location. An IP address has two primary functions: it identifies the host, or more particularly its network interface; and it indicates the host's position in the network, allowing a path to be established to that host. IP addresses can be either Public or Private. Read through this article to ... Read More

A Metropolitan Area Network (MAN) is a medium-sized network but it covers a larger area than a LAN. It often covers multiple cities or towns. In contrast, a Wide Area Network (WAN) is a much larger network than LAN and MAN. A WAN in general is a network of local area networks (LANs) that link to other LANs via telephone lines and radio waves. Go through this article to find out more about MAN and WAN and how they are different from each other. What is a Metropolitan Area Network (MAN)? A MAN is comparable to a ... Read More

Both LAN and MAN are computer networks that differ in terms of the geographical area they cover. LANs are private networks limited to a particular geographical area in the range of a few kilometers, while MANs cover a larger area that can span multiple cities and towns.Read through this article to find out the major differences between a LAN and a MAN.Local Area Network (LAN)A Local Area Network is a private network that connects computers and devices within a limited area like an office, a building, or a campus. On a small scale, LANs are used to connect personal computers ... Read More

Frequency Division Multiplexing (FDM) is an analog method which is used when the bandwidth of a connection is higher than the linked bandwidth of the signals which are to be communicatedTime Division Multiplexing (TDM) is a digital method where each sender is given the entire possession of the whole bandwidth of the channel for a fixed duration of time. After this, the control is given to the next sender, and the process continues on a round-robin basis.Read through this article to find out how these two multiplexing techniques work and what are the major differences between TDM and FDM.What is ...

A stateless protocol is one in which each communication is treated as a separate event, unrelated to other communications of the same type.A stateful protocol, on the other hand, is the polar opposite of a stateless protocol, in which each communication is treated as part of a broader sequence.Read through this article to find out more about stateless and stateful protocols and how they are different from each other.What is Stateful Protocol?In Stateful Protocol, when a client sends a request to the server, it expects a response; it resends the request if it does not receive one.Stateful applications and procedures ...
