Circuit switching is a network configuration operates almost the same way as the telephone system works. In this network configuration, two network endpoints are connected via a dedicated physical path for the duration of the dedicated connection.  Before communication to occur, there needs to be a complete end-to-end channel. Regular telephone service makes use of circuit switching.  There are three phase of circuit switching which are as follows: Circuit Establishment: A dedicated physical route is established between the sender and the receiver. The path may include a nu ..read more

This post is cover the advantages and disadvantages of packet switching. Some main Advantages and Disadvantages of Packet Switching are as follows.  What is Packet Switching? Packet switching is a digital network communication method that groups all transmitted data into suitable small  sized blocks, call packets, which are transmitted via a medium that may be shared  by multiple simultaneous communication sessions. Packet switching increase network efficiency, robustness, enables technology convergence of many applications operating on the same network. Following are the Advant ..read more

This article gives the Advantages and Disadvantages of Message Switching.  What is Message Switching? Message Switching The smallest individual unit is a message. The sender and recipient do not have a direct connection either. Many intermediate nodes transmit out data to guarantee that the message gets to its target recipient. Thus message switched data networks are sometimes known as hop-by-hop networks. Message switching is lower complexity, highly reliable, and reduces traffic congestion. Message switching requires more time than packet switching since the entire message continues ..read more

When selecting the best two-way radio for your purposes, it can be helpful to know the difference between UHF or ultra-high frequency and VHF or very high frequency.  Which is better UHF or VHF? So let us check out the difference between UHF and VHF to better understand this topic. What is the difference between UHF and VHF? What is UHF? UHF stands for ultra-high frequency. Within the electromagnetic spectrum, it is the range of radio frequencies that fall between 300 MHz and 3 GHz. UHF signals are widely utilised in radio and television broadcasting, usually delivering TV signals on ..read more

The visible region of the electromagnetic spectrum is known as visible light. It is the range of wavelengths that causes humans to perceive brightness and colour. It is located between UV and infrared radiation and most people can visually detect wavelengths between approximately 400 nanometers and 780 nanometers. Here this article gives the application of visible light to better understand this topic. What are the applications of Visible light? Photography: One of the use of visible light can be essential use for photography, as cameras capture light reflecting off objects to create images ..read more

What is ultra-high frequency(UHF)? The band of electromagnetic radiation with a radio frequency range of 300 MHz to 3 GHz is known as ultra-high frequency(UHF). With a wavelength ranging from 1 to 1 dm, this band is also referred to as the decimeter band. UHF radiation is less impacted by environmental conditions, they are more frequently utilised for channel broadcasting and TV and radio transmission. They have high directivity, but the receiving error also rises at the same time. UHF radio uses a wide variety of frequencies: 450 MHz:  Commercial radio services, such as land mobile radi ..read more

When there is a line of sight(LOS) between the sender and the receiver, infrared technology uses focused light instead of light that is diffuse and reflected at objects like walls and furniture. One type of electromagnetic radiation that is included in the electromagnetic spectrum is infrared light. It is undetectable to the human eye and originates from heat and thermal radiation. Senders in infrared transmission might be as basic as laser diodes or light-emitting diodes (LEDs).  Massive bandwidth that is available for usage but has not yet been fully utilised is the benefit of infrared ..read more

Has your PC performance slowed down? Are you planning to upgrade your HDD to SSD? Or Are you looking to build a new Desktop PC in near future? Let's deep dive into HDD Vs SSD to help you to decide which one is better option?  If your need is storage capacity and your budget is lower then HDD is a better option, but if you want good powerful performance, reduce computer boot time, and overall speed is important and your budget is higher then SSD is the better option.  ..read more

Some points on advantages and disadvantages of are discussed here. So let us check about the advantages and disadvantages to know more about Ultra High Frequency (UHF). UHF is a short-range communication frequency band that works in the 300 MHZ - 3 GHZ bands. Because radio waves in these bands are compact, operate at higher frequencies, and have strong signal penetration, UHF can communicate through objects like walls and concrete. This makes it useful in indoor and outdoor environments as well as built-up areas.  Ultra High-Frequency(UHF) Advantages UHF is frequently used by public safe ..read more

This article discusses the advantages and disadvantages of radio transmission. Data can be sent across shorter and greater distances using radio transmission, which uses radio waves that are then converted to electromagnetic signals to travel over villages, cities, and entire nations. Depending on the surroundings, AM or FM techniques work to amplify radio waves that are used for data sensing and receiving. Following are some advantages and disadvantages of radio transmission to better understand about this topic. Advantages of Radio transmission Compared to infrared, which uses infrared ligh ..read more
