Modern home networks support a wide range of devices including computers, smartphones, smart TVs, gaming consoles, printers, security cameras, and Internet of Things (IoT) devices.<\/p>\n<p class=\"isSelectedEnd\">Most home networks today are built around a broadband internet connection supplied by an Internet Service Provider (ISP), combined with a wireless router that distributes internet access throughout the home.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h1>Typical Home Network Components<\/h1>\n<h2>1. Internet Service Provider (ISP)<\/h2>\n<p class=\"isSelectedEnd\">The ISP delivers internet connectivity to the home using technologies such as:<\/p>\n<ul data-spread=\"false\">\n<li>Fibre Optic<\/li>\n<li>Cable<\/li>\n<li>DSL<\/li>\n<li>Fixed Wireless<\/li>\n<li>Satellite<\/li>\n<li>Mobile Broadband (4G\/5G)<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The internet connection enters the home through a modem or Optical Network Terminal (ONT).<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2>2. Modem or ONT<\/h2>\n<h3>Modem<\/h3>\n<p class=\"isSelectedEnd\">A modem converts signals from the ISP into standard Ethernet networking signals used by home equipment.<\/p>\n<h3>ONT<\/h3>\n<p class=\"isSelectedEnd\">For fibre connections, an Optical Network Terminal performs a similar function.<\/p>\n<p class=\"isSelectedEnd\">Some ISP-supplied devices combine the modem and router into a single unit.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2>3. Router<\/h2>\n<p class=\"isSelectedEnd\">The router is the central device in the home network. Its responsibilities include:<\/p>\n<ul data-spread=\"false\">\n<li>Connecting the home to the internet<\/li>\n<li>Assigning IP addresses using DHCP<\/li>\n<li>Performing Network Address Translation (NAT)<\/li>\n<li>Managing firewall security<\/li>\n<li>Routing traffic between devices<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Most home routers also include:<\/p>\n<ul data-spread=\"false\">\n<li>Built-in Wi-Fi access points<\/li>\n<li>Ethernet switch ports<\/li>\n<li>Guest wireless networks<\/li>\n<li>Basic parental controls<\/li>\n<\/ul>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2>4. Wi-Fi Access Point<\/h2>\n<p class=\"isSelectedEnd\">The Wi-Fi access point provides wireless connectivity for mobile and smart devices.<\/p>\n<p class=\"isSelectedEnd\">Modern standards include:<\/p>\n<ul data-spread=\"false\">\n<li>Wi-Fi 5 (802.11ac)<\/li>\n<li>Wi-Fi 6 \/ 6E (802.11ax)<\/li>\n<li>Wi-Fi 7 (newer deployments)<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Large homes may use:<\/p>\n<ul data-spread=\"false\">\n<li>Mesh Wi-Fi systems<\/li>\n<li>Additional access points<\/li>\n<li>Wi-Fi extenders<\/li>\n<\/ul>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2>5. Ethernet Switch<\/h2>\n<p class=\"isSelectedEnd\">An Ethernet switch expands the number of wired network ports available.<\/p>\n<p class=\"isSelectedEnd\">Switches are commonly used for:<\/p>\n<ul data-spread=\"false\">\n<li>Desktop PCs<\/li>\n<li>Gaming consoles<\/li>\n<li>Network Attached Storage (NAS)<\/li>\n<li>Smart TVs<\/li>\n<li>Security systems<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Wired connections generally provide:<\/p>\n<ul data-spread=\"false\">\n<li>Higher speeds<\/li>\n<li>Lower latency<\/li>\n<li>Greater reliability<\/li>\n<\/ul>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2>6.
