How does a wired network work and what is its connection to the internet?
In a wired network, computers are connected to the internet using Ethernet cables. One end of the cable plugs into the computer, while the other end plugs into a modem or router. The copper wire inside the cable transfers information via an electrical current to and from both ends. This connection allows the computer to access the internet, which is a vast network of connected computers.

What is the role of a modem and router in a wired network?
A modem and router work together in a wired network to connect the computer to the internet. The modem receives data from the internet service provider (ISP) and converts it into a format that can be understood by the computer. The router then distributes this data to the connected devices within the network, allowing them to access the internet.

Study Notes
Wi-Fi: Definition and Importance
- Wi-Fi stands for Wireless Fidelity, a technology enabling wireless communication over a local area network (LAN).
- Provides high-speed internet access to devices without the need for physical cables, enhancing convenience.
- Essential in many everyday settings like homes, schools, cafes, and offices, facilitating connectivity for smartphones, tablets, laptops, and smart devices.
Wired Networks: Functionality and Internet Connection
- A wired network relies on physical cables (like Ethernet) to connect devices to a local area network (LAN).
- Provides stable and faster internet connections compared to wireless due to reduced interference and signal loss.
- Devices in a wired network communicate via switches and routers to access the internet, transmitting data as electrical signals over cables.
Modem and Router: Key Components in Wired Networks
- A modem connects to the internet service provider (ISP), converting analog signals to digital for data transmission.
- A router receives data from the modem and distributes it to connected devices within the local network.
- Together, they manage data traffic and ensure seamless internet access for multiple devices.
Differences Between Wi-Fi and Wired Networks
- Wi-Fi offers flexibility and mobility, allowing devices to connect from various locations within range, while wired networks require physical connections, restricting movement.
- Wired networks typically deliver higher speeds and reliability, whereas Wi-Fi connections may experience interference and reduced speeds due to physical barriers and distance.
Role of Wi-Fi in Modern Life
- Wi-Fi has become integral to daily activities like streaming, online work, and social networking, enhancing communication and entertainment.
- Enables the growth of smart home technology, allowing devices like thermostats, lights, and security systems to connect remotely.
- Facilitates increased productivity by providing access to information and resources anytime and anywhere, transforming how people interact and work.
