What is WiMAX Technology & Its Working

June 12, 2021 By WatElectronics

WiMAX Modem

Technology like wireless broadband provides a connection with high-speed over the air. This kind of technology utilizes radio signals to send & receive data from the users directly whenever they desire it. Different wireless technologies work together like WiFI, 3G, UWB & WiMax technology to meet up customer requirements. Wireless broadband (WBA) is a point to multipoint system that is made up of subscriber equipment & base station. The base station works through an external antenna … [Read more...]

What is a Bridge in Computer Network & Its Working

June 8, 2021 By WatElectronics

Computer Network

In information technology, computer networks are the group of computers that are connected to perform communication and transfer the data and resources to another computer. The data stored in one computer can be accessed in another computer very easily when they are connected to only one network. These are used to communicate and share devices such as scanners, printers, and photocopiers. To provide communication or interaction between the computers/hosts and hardware on the computer network, … [Read more...]

What is Bus Topology : Working & Its Examples

June 5, 2021 By WatElectronics

Bus Topology in Computer Network

In a computer network, the network topology is the geometric representation of how different devices, nodes are interconnected logically or physically to each other. There are different ways to arrange a computer network where each has pros and cons based on the requirement of your computer. Some network arrangements can provide you high security and connectivity. In a computer network, there are five types of network topologies like mesh, point to point, star, ring, bus, tree, and hybrid. From … [Read more...]

What are Network Devices : Types & Their Working

June 4, 2021 By WatElectronics

Network Devices Types

The development of computer networking started with the progress of Arpanet in the period of the ending of the 1960s and in the initial stages of the 1970s. Before the networking devices, there were computer vendor networks which are mainly constructed to associate connection between terminals and remote job entry locations with that of the mainframe. Whereas the crucial thought behind the networking was to accomplish network sharing and it was the basis in the ARPANET design. It is even more … [Read more...]

What are Network Nodes : Types & Their Working

May 31, 2021 By WatElectronics

Network Nodes in Computer Network

In Data Communication Systems, a network is an interconnecting point to exchange information between various communication components connected by various communication network links. If two or more network devices are connected to each other to transfer and share information and resources within a geographical area, then it is called a network. For example, a computer network is formed with multiple computers connected to transmit, exchange, share, store data, and resources. It enables … [Read more...]

What is Optical Time-Domain Reflectometer & Its Working

May 14, 2021 By WatElectronics

Optical Time-Domain Reflectometer

For better communication to take place between two ends, there should be a proper transmission of information from one end to another. There has been a tremendous evolution of the communication systems to make the communication process faster, reliable, and safer. It has evolved from analog to digital, wired to wireless. One of the modes of communication that are highly used nowadays is Fiber Optic Communication. In this mode, using infrared ray pulses information is transmitted from one place … [Read more...]

What is Modbus : Working & Its Function Codes

May 11, 2021 By WatElectronics

Modbus

In 1979, a data communication protocol called Modbus was developed by Modicon (now Schneider Electric) and it is used along with its PLCs (programmable logic controllers). It is an industrial standard protocol and it is mainly used in process and factory automation. Now it is commonly referred to as a de facto communication protocol to connect various industrial electronic components. In the electric power industry, this is used to connect a supervisory computer with RTU (remote terminal unit) … [Read more...]

What is Transport Layer : Elements & Security

May 6, 2021 By WatElectronics

Transport Layer in OSI Model

A reference model like OSI is frequently used in mode communication, which states that how the data is communicated between two software applications in the computer. This model comprises 7 layers where each layer has its own security protocols and responsibilities. This was developed in the year 1984 by ISO (International Organization for Standard) and today the model is defined as an architectural approach of inter-computer communications. As every layer in the OSI model is aligned with … [Read more...]

What is a Virtual LAN : Architecture & Its Types

March 5, 2021 By WatElectronics

VLAN

These days, the communication network has been implemented with the growing technology. The communication between the computer networks is achieved very easily by dividing the networks into Local Area Networks (LANs) and Wide Area Networks (WANs). When all the physical devices of the network are connected to each other within the same network using a switch link, then it is called LAN. It is mainly used for official purposes. Similarly when the various networks with logical workstations are … [Read more...]

What is Spectrum Analyzer : Types & Its Applications

February 25, 2021 By WatElectronics

Spectrum Analyzer

The one device which is more prominent in this digital industry is Spectrum Analyzer. This device holds a nearly 50-year history which consists of surmounting multiple complications in introducing the product to the real-time market. The development of the device initially took place at Applied Research Laboratories of Columbia University. The first developed spectrum uses glass acoustic delay lines, and it delivers real-time processing in the range of 1 – 40 kHz. And the initial development … [Read more...]
