WiFi is a wireless network to connect nearby devices with each other and share the Internet via hotspots. Ethernet, on the other hand, is a LAN network standard used in wired LAN. Go through this article to find out more about the features of WiFi and Ethernet and how they are different from each other.What is WiFi?WiFi stands for Wireless Fidelity. It defines any network based on the 802.11 standards, allows computers and devices with the required wireless capacity to communicate via radio waves with other computers or devices. IEEE established the 802.11 network standards, which describe how two wireless ... Read More

As an analogy, we can think of connection-oriented services as telephone systems, where a connection needs to be established between a sender and a receiver before they can exchange data. In contrast, connection-less services are like traditional postal systems where data exchange can take place between a sender and a receiver without establishing a connection. Go through this article to find out the major differences between connection-oriented and connection-less services. What is Connection-oriented Service? A connection-oriented service is a data transfer mechanism used at the session layer. In contrast to its opposite, connectionless service, connection-oriented service necessitates establishing a session ... Read More

All these three protocols provide a mechanism for flow control. Read through this article to get a basic overview of Stop and Wait, Go-Back-N, and Selective Repeat protocols. Stop and Wait Protocol It is the most fundamental flow control strategy. The transmitter sends one frame at a time to the receiver using this method. The transmitter will come to a halt and wait for the receiver to respond. The interval between sending a message and receiving an acknowledgment is known as the sender's waiting time, and the sender is idle during this time. After receiving an acknowledgment (ACK), the ...

Static Routing or Non-Adaptive Routing follows user-defined routing. Here, the routing table is not changed until the network administrator changes it. Static Routing uses simple routing algorithms and provides more security than dynamic routing. Dynamic Routing or Adaptive Routing, as the name suggests, changes the routing table if there is any change in the network topology. During network change, dynamic routing sends a signal to router, recalculates the routes and sends the updated routing information. Read through this article to find out how Static Routing differs from Dynamic Routing. What is Static Routing? One of the essential techniques ... Read More

Optical fibre and Coaxial cables, both are different types of guided media cables. Optical fibre is made up of plastic and glass and is used to transmits signals in form of light or optics whereas coaxial cable is made using plastic and copper wires and is used to transmits signals in form of electric signals.The following are some of the important differences between Optical fibre and Coaxial cable.Sr. No.KeyOptical FibreCoaxial Cable1Transmission TypeOptical Fibre transmits data/signals in the form of light.The coaxial cable transmits data/signals in the form of electrical signals.2MaterialOptical fibre is made using plastic and glass.Coaxial cable is prepared ...

Orthogonal frequency division multiple access (OFDMA) is a multi-user version of digital data modulation scheme OFDM (orthogonal frequency division multiplexing). In OFDM, a single stream of data is divided into several separate sub-streams for transmission via multiple channels. OFDM uses the principle of frequency division multiplexing (FDM), where the available bandwidth is divided into a set of sub-streams having separate frequency bands.In OFDMA, multiple access is achieved by assignment of different subsets of subcarriers to individual stations. This permits transmission to go on simultaneously at lower data rate from several stations.The stations assigned to a given subcarrier alternate between sending ... Read More

The IEEE 802.16 is a set of standards that lays down the specifications for wireless broadband technology. It has been commercialized as Worldwide Interoperability for Microwave Access (WiMAX) that is responsible for delivery of last mile wireless broadband access. It lays down the standards for both physical layer as well as medium access control (MAC) layer for WiMAX.Physical Layer Features of WiMAXThere are two popular services of the physical layer −Fixed WiMAX.Mobile WiMAX.WiMAX initially provided data rates of 30 – 40 Mbps. The updated version that came in 2011 provides up to 1 Gbps data rates for fixed stations.It operates ... Read More
