Thé évolution of computer network câble connectivity

 The evolution of computer network connectivity has gone through several phases, from the early days of wired networks to the current era of wireless communication.

Wired Networks: The first computer networks were established in the 1960s, using coaxial cables and other physical media to transmit data between computers. These early networks were slow and unreliable, but they laid the groundwork for the development of more sophisticated network technologies.

Ethernet: In the 1970s, Ethernet was invented, which allowed for the creation of local area networks (LANs) using coaxial cables. Ethernet became the most popular LAN technology, and it remains in use today.

Twisted Pair Cable: In the 1990s, twisted pair cable was introduced, which improved the performance of Ethernet and made it possible to transmit data at faster speeds over longer distances. Twisted pair cable remains in use today, particularly in enterprise networks.

Fiber Optics: In the 1980s and 1990s, fiber optic cables were developed, which offered even faster speeds and longer distances than twisted pair cable. Fiber optic cables are now used extensively in backbone networks, as well as in some enterprise networks and homes.

Wireless Networks: In the late 1990s and early 2000s, wireless networks began to gain popularity. The first wireless standard was 802.11, which allowed for wireless LANs (WLANs) using radio waves to transmit data. Since then, many new wireless standards have been developed, including 3G, 4G, and 5G cellular networks, which have greatly expanded the capabilities of wireless communication.

Today, both wired and wireless networks are used extensively, with each technology serving different needs and use cases. Wired networks are still preferred in many situations where reliability and speed are critical, such as in enterprise networks and data centers. However, wireless networks have become essential for mobile devices and remote access, and they are increasingly being used in smart homes, smart cities, and other emerging application
