Working and Difference between Wifi Router & Modem | Detailed Video in Hindi.

A modem and a Wi-Fi router are two distinct devices that serve different purposes in a home or office network. They are often used together to provide internet connectivity and wireless networking capabilities. Here are the key differences between them Function: Modem (Modulator-Demodulator): A modem is a device that connects your home or office network to the internet service provided by your internet service provider (ISP). It converts digital data from your computer or network into analog signals for transmission over a telephone line, cable line, fiber-optic line, or other types of communication lines. It also demodulates incoming analog signals from the ISP back into digital data that your network can understand. Wi-Fi Router: A Wi-Fi router, on the other hand, is responsible for creating a local wireless network within your home or office. It allows multiple devices (such as smartphones, laptops, tablets, and smart home devices) to connect to the internet wirelessly and communicate with each other within your local network. It also manages the distribution of IP addresses to devices on your network and handles network security features. Connectivity: Modem: A modem typically has one or more ports for connecting to the internet service provider's network infrastructure, such as a cable or DSL line. It lacks the capability to provide wireless connectivity to devices. Wi-Fi Router: A Wi-Fi router is equipped with multiple Ethernet ports for wired connections and provides wireless connectivity through Wi-Fi. It allows you to connect multiple devices to the internet and each other using wireless technology. Networking Features: Modem: Modems are primarily focused on the task of facilitating the connection to the internet. They do not offer advanced networking features, such as DHCP (Dynamic Host Configuration Protocol) for IP address assignment, firewall capabilities, or the ability to create a local network. Wi-Fi Router: Wi-Fi routers offer a range of advanced networking features, including DHCP, NAT (Network Address Translation), firewall protection, QoS (Quality of Service) settings for traffic prioritization, and more. They provide the infrastructure for creating a local network, managing device connections, and ensuring network security. Combination Devices: Some modern networking devices combine the functions of a modem and a Wi-Fi router into a single unit. These are often referred to as "modem-router combos" or "gateway devices." They simplify the setup process for users and are commonly provided by ISPs for home internet connections.
