Description: The ‘Wired Protocol’ refers to a set of rules and standards that enable data communication through physical cables. These protocols are fundamental for establishing stable and efficient connections in computer networks, ensuring that information is transmitted correctly and in the proper order. Key features of wired protocols include the ability to handle different types of data traffic, error detection and correction, and flow management. One of the most well-known protocols in this category is Ethernet, which has evolved from its early versions in the 1970s to become the dominant standard for local area networks (LAN). Wired protocols are essential in various environments where connection stability and speed are critical, such as in offices, data centers, and industrial applications. Their relevance lies in the need for reliable and fast communication, especially in an increasingly interconnected world where data transfer is constant and vital for the operation of various applications and services.
History: The Ethernet protocol was developed by Robert Metcalfe and his team at Xerox PARC in 1973. Originally designed to connect computers in a local area network, Ethernet has undergone several revisions and improvements over the years, including increasing data transmission speeds from 10 Mbps in its early days to 100 Gbps and beyond in modern versions. As technology has advanced, Ethernet has become the predominant standard for wired networks, surpassing other protocols such as Token Ring and FDDI.
Uses: Wired protocols are primarily used in local area networks (LANs), where fast and reliable connections are required. They are common in business environments, where computers, printers, and servers are connected via Ethernet cables. They are also used in various applications for automation and process control, as well as in video surveillance systems and real-time data transmission.
Examples: A practical example of the use of wired protocols is an office network where multiple computers are connected to a switch via Ethernet cables, allowing communication between devices and access to the Internet. Another example is the connection of security cameras to a recording system via coaxial or Ethernet cables, ensuring high-quality video transmission.
