Wired communications

It is any type of data and information transfer within communication networks between devices using a wired connection. It also includes wired Ethernet connections, fiber optic cables for telephone and other uses, cables for television and Internet systems, PSTN, and CAN and MOST systems in automobiles.

Wired connectivity is the use of wires and cables to connect devices and systems to each other. A wired connection is usually made by attaching electrical conductive tape to the terminals of devices or systems. Programming is also used in this type of communication.

Wired communication methods refer to the transmission of data or signals over physical connections such as cables, wires, and networks.

It should be noted that communication networks include two types of communication: wired communication, which we are talking about today, and wireless communication.

Advantages of wired communications

Wired communications refers to the transfer of information and data over physical cables or wires. There are different uses and advantages of wired communications in different contexts. Some common uses include:

  1. High Bandwidth: Wired connections often provide higher bandwidth compared to wireless connections. This allows for faster data transfer rates, making a wired connection suitable for applications that require transferring large amounts of data quickly, such as streaming high-definition video or transferring large files.
  2. Security: A wired connection is usually more secure than a wireless connection, as the physical connection makes it difficult for unauthorized users to intercept data. This is especially important in sensitive applications such as banking, healthcare, and government communications.
  3. Stability in remote areas: In remote or rural areas where wireless coverage may be limited, wired communications infrastructure can be more reliable and cost-effective for establishing communications.
  4. Power over Ethernet (PoE): Ethernet cables, typically used for wired communications, can carry electrical power along with data. This feature, known as Power over Ethernet (PoE), is useful for powering devices such as IP cameras, VoIP phones, and other networked devices without the need for a separate power supply.
  5. Consistent Performance: Wired communications systems provide consistent performance without being affected by factors such as signal strength, interference, or obstructions that can affect wireless signals.
  6. Fiber Optic Communications: Fiber optic cables, a type of wired communications media, provide extremely high bandwidth and are immune to electromagnetic interference. They are commonly used for long-distance communications, including high-speed Internet connections and long-distance communications.
  7. Cost-effective for fixed installations: In scenarios where the infrastructure is already in place, such as in homes, offices, and data centers, a wired connection can be more cost-effective for fixed installations than a wireless network setup.
  8. Despite the advantages of wired connectivity, it is essential to note that wireless technologies also play a crucial role in various applications, providing mobility and convenience that wired solutions may not provide. The choice between wired and wireless connectivity depends on the specific requirements and limitations of a particular scenario.

Types of wire connections

  • The pair is scheduled.

It consists of a pair of wires twisted together, where the twist of noise on the wire is defined by the cancellation of a certain limit, the amount of electromagnetic interference from the environment between transmission and reception, and twisted pair wire Twisted pair wire is a copper wire that connects the personal computer at home or at work to improve the telephone as a material Produced as twisted wire; The two wires are insulated, preventing the wires from being crossed and twisted.

Isolating the media also helps to reduce the crossing of telephone lines, and they are considered twisted pair of copper, and it is because it is the lowest speed communication tool and the frequency with which communication signals are slow and is not found in other media that are known to average in carrying “1-128 Mbps.” the second".

  • Coaxial cables.

Coaxial cables consist of a cylindrical wire running down the middle of an insulating sheath. The insulating sheath is surrounded by a conductive sheath that acts both as a shield and a return path for the signal. Coaxial cables are highly resistant to noise due to the shielding that keeps most of the electromagnetic energy within the surrounding conductor sheath.

  • Optical fiber cable.

Fiber optic cable consists of very thin and long glass fibers into which light pulses can be sent. The data rates supported by fiber optic networks are incredibly fast, as it is very fast in fact. Optical fibers have become one of the most technological developments for transmitting information, and this innovative material has revolutionized communications operations, modern telecommunications use electricity, light, or radio to transmit sounds, images, and data.

Optical fibers, instead of spreading sound waves, transmit data in the form of light pulses with the great advantage that the luminous pulses are transmitted without interruption, as the information is transmitted by light waves and not by electricity, which leads to avoiding electrical noise interference and signal degradation. It also A means of transmitting data in the form of light.

One of the advantages of the fiber optic system is its ability to carry the equivalent of an encyclopedia's set of information in one second and transmit data over long distances of more than 100 km. It is electrically insulating, easy to install, and has long continuous lengths.

Wired networks

Dial-up network.

Dial-up communication is almost extinct now, but it is worth mentioning briefly because the first method used to access the Internet on a large scale was the dial-up network, which enabled the emergence of the wired digital communications revolution. With wired telephony, only one form of communication can pass through the channel. A dial-up modem converts digital signals from a computer into analog signals that pass over a telephone line by initiating a "phone call" to an Internet service provider's server.

Network cable connection.

A cable Internet connection is a form of wired-to-broadband communication. Through the use of a cable modem, users can access the Internet over wired cable TV lines. Modems can provide very fast access to the Internet over wired cables, making a cable connection an option. Applicable for many

Digital subscriber line network.

DSL (Digital Subscriber Line) uses copper telephone lines by connecting two separate wires to the user so that service is provided at the same time as landline telephone service. Two separate wires provide the ability for customers to make calls while surfing the Internet.

Fiber optic network.

Fiber Internet services are among the best home broadband options on the market offered by companies, and they use optical signals to transmit information compared to traditional wired cable lines.
