How does arpa work?
Arpa (Automatic Repeat reQuest) is a protocol used in telecommunications to ensure reliable data transmission over unreliable networks. When data packets are lost or corrupted during transmission, Arpa triggers retransmission requests to recover the lost data. It helps in maintaining data integrity and minimizing transmission errors in network communication.
Why ABCD parameters are called as transmission parameter?
ABCD parameters are called transmission parameters because they describe the relationship between the input and output voltages and currents of a two-port network, which helps in understanding how signals are transmitted through the network. They are used to analyze the transmission characteristics of linear electrical networks.
What are some examples of Microwaves transmission?
Some examples of microwave transmission include satellite communication, terrestrial point-to-point communication networks, wireless local area networks (Wi-Fi), and radar systems used in aircraft navigation and weather monitoring.
What are the key differences between AC and DC transmission systems, and how do these differences impact the efficiency and reliability of power distribution networks?
AC (alternating current) transmission systems use a back-and-forth flow of electricity, while DC (direct current) systems have a one-way flow. AC systems are better for long-distance transmission due to lower energy losses, but DC systems are more efficient for high-voltage transmission over shorter distances. AC systems are more common and easier to convert voltages, but DC systems are more reliable for transmitting large amounts of power over long distances. The choice between AC and DC impacts the efficiency and reliability of power distribution networks based on factors like distance, voltage levels, and power requirements.
What is the meaning of bridge in physics?
In physics, a bridge refers to a circuit that connects two or more networks together. It is used to transfer signals or data between different parts of a system, such as in electronic circuits or communication networks, without mixing or altering them. Bridges can help improve the efficiency and reliability of signal transmission in complex systems.
What is the function of burden resistors?
To load a circuit to a specific resistance value. This is useful in impedance matching networks, power transmission, telecommunications, etc.

What does Insertion loss refers to in telecommunications?
Insertion loss in telecommunications refers to the reduction in signal strength that occurs when a device, such as a connector, filter, or switch, is inserted into a transmission line. It is typically expressed in decibels (dB) and quantifies how much power is lost as the signal passes through the device. High insertion loss can negatively impact the performance of a communication system by degrading signal quality and reducing overall system efficiency. Minimizing insertion loss is crucial for maintaining optimal signal integrity and performance in telecommunications networks.
What is dedicated ground?
Dedicated ground refers to a specific area or network of infrastructure exclusively reserved for a particular use, such as transportation, logistics, or telecommunications. In logistics, it often involves dedicated routes or facilities for the transport of goods, ensuring efficiency and reliability. This concept can also apply to telecommunications, where dedicated ground networks provide stable and secure connections for data transmission. The primary advantage is optimized performance tailored to specific operational needs.
What are computer netwoks?
Computer networks are telecommunications networks that allow computers to exchange information (data), a good example is the Internet.
