  3. INTRODUCTI0N • We say ‘Wired Network Technology”. • In computing terminology, the term “wired” is basically used to differentiate between wireless connections and those that involves cables. • The transmission of data over a wire-based communication technology and that technology is known as wired technology.
  4. HISTORY Some of the most defining moments in the history of wired network technology, which influenced the advancements it’s making today, include: • 1876: The invention of the telephone started a revolution towards wired communications. • 1964: With the introduction of optical fiber, the potential of wired networks skyrocketed. • 1970: Ethernet technology, which uses a coaxial-based or twisted copper transport system, was developed. • 1980: During this decade, researchers built the foundation for a digital subscriber line (DSL). • 2000: Broadband technology became available to consumers. Today, more than 20 million users trust it.
  5. WIRED OVER WIRELESS • Wired may refer to peripheral devices as well. Since many keyboards and mice are now wireless, "wired" is often used to describe input devices that connect to a USB port. • Peripherals such as monitors and external hard drives also use cables, but they are rarely called wired devices since wireless options are generally not available.
  6. • While many peripherals are now wireless, some users still prefer wired devices, since they have a few benefits over their wireless counterparts. For example, an Ethernet connection is not prone to signal interference that can slow down Wi-Fi connections. Additionally, wired network connections are often faster than wireless ones, which allows for faster data transfer rates. Some users also prefer wired peripherals since their is no need to replace batteries on a regular basis. Gamers especially prefer wired keyboards and mouce since they have lower latency and can be backlit, thanks to the power provided by the USB connection. • It continues to evolve and test the limits of speed as researchers discover faster ways to transmit data.
  7. TYPES OF WIRES OR CABLES • Coaxial Cables-used in TV, Computer systems • CCTV Cables-used for CCTV cameras • Ethernet Cables-used for LAN connections • Telephone Cables-used for landlines • Jelly Filled Cables-used underground
  8. ADVANTAGES • Reliable – Not affected by other wireless signals(portable/cellular phones, microwaves,etc) • Price – Wire is cheap • High life expectancy • High speed • QoS(Quality of Service)
