Ethernet switches allow all wired devices, such as computers, laptops, printers and wireless access points, routers to connect to transmit and receive data. In the following article, DNG Corp will introduce to readers all the information about what an Ethernet Switch is, its features and how to classify the device in the most detailed way.<\/div>\n<h2 style=\"text-align: justify;\"><strong>What is an Ethernet Switch?<\/strong><\/h2>\n<div style=\"text-align: justify;\">An Ethernet Switch is a network connection device and uses multiple ports to communicate between other devices in the LAN using Ethernet cables. Ethernet switches are used to connect wired devices such as computers, laptops, routers, servers and printers to a local area network (LAN). In addition, multiple Ethernet switch ports allow faster connections and smoother access to multiple devices at the same time.<\/div>\n<p><span style=\"font-weight: 400;\">=&gt; See more: <a href=\"https:\/\/dngcorp.vn\/multilayer-switch-la-gi\/\">What is Multilayer Switch? How to use it effectively<\/a><\/span><\/p>\n<div>An Ethernet switch differs from a router in that it allows for network connectivity and uses only a single LAN and WAN port. Unlike an Ethernet hub, which sends packets to all ports, an Ethernet switch has the ability to understand the packet&#8217;s addressing scheme and send packets to their correct destination port, thus limiting the number of data collisions sent to the destination port at the same time.<\/div>\n<div><\/div>\n<div>However, most corporate networks use a combination of switches, routers, and hubs, as well as wired and wireless technologies.<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-9538 size-full\" src=\"https:\/\/dngcorp.vn\/wp-content\/uploads\/2024\/05\/ethernet-switch-1.jpg\" alt=\"What is Ethernet Switch?\" width=\"800\" height=\"500\" \/><\/p>\n<p style=\"text-align: center;\"><em>What is Ethernet Switch?<\/em><\/p>\n<h2 style=\"text-align: justify;\"><strong>How Does an Ethernet Switch Work?<\/strong><\/h2>\n<div style=\"text-align: justify;\">An Ethernet switch provides connectivity for multiple devices to each other using physical cables. That is, the devices will either connect to the same switch or to another switch on the same network. These cables include: coaxial cable, fiber optic cable, and twisted pair Ethernet cable.<\/div>\n<div style=\"text-align: justify;\">Once a device is connected to a port, the Ethernet switch will manage the flow of data between the devices and other applications, data, cloud services, and the internet. The switching process will direct data to and from the correct port on the Switch based on the port of the sending device as well as the sending and destination MAC addresses. The MAC addresses of both the sender and destination are identical to the data sent in the Ethernet frame.<\/div>\n<div style=\"text-align: justify;\">Every Ethernet-compatible device has a hard-coded physical address called a MAC address that the connected switch uses to uniquely identify a device.<\/div>\n<div style=\"text-align: justify;\">When a Switch receives an Ethernet packet, it stores the sending device&#8217;s MAC address and the port it is connected to in a locally stored table called the MAC address table. The Switch then checks the MAC address table to see if the destination MAC address is connected to the same switch. If it is, the Switch forwards the packet to the known destination port. If not, the Switch broadcasts the packet to all ports and waits for a response.<\/div>\n<div style=\"text-align: justify;\">If the switch is directly connected to the destination device, the device accepts the data packet, responds, and the transmission is complete. If the device is connected to another Switch, the next Switch repeats the lookup and forwarding process until the frame reaches its intended destination.<\/div>\n<figure id=\"attachment_9540\" aria-describedby=\"caption-attachment-9540\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-9540 size-full\" src=\"https:\/\/dngcorp.vn\/wp-content\/uploads\/2024\/05\/ethernet-switch-2.jpg\" alt=\"What is Ethernet Switch?\" width=\"800\" height=\"500\" \/><figcaption id=\"caption-attachment-9540\" class=\"wp-caption-text\"><em>How does Ethernet switching work?<\/em><\/figcaption><\/figure>\n<div><\/div>\n<div style=\"text-align: justify;\">In addition, Ethernet switches are researched and manufactured in many types to be able to handle different network sizes or structures: access, distribution and core. Switched networks often have a tree-root structure, with small switches connected to devices at the access edge, larger switches acting as distribution, and then core switches.<\/div>\n<h2 style=\"text-align: justify;\"><strong>Popular Ethernet Switch Types<\/strong><\/h2>\n<div style=\"text-align: justify;\">The demand for Ethernet switches is increasing today. Accordingly, manufacturers also research and develop many types to suit different access network needs. DNG Corp has summarized for readers the popular Ethernet Switch types today:<\/div>\n<h3 style=\"text-align: justify;\"><strong>By feature<\/strong><\/h3>\n<div style=\"text-align: justify;\">&#8211; Managed Ethernet Switch: Managed switches offer a wide range of configuration options, especially suitable for medium and large enterprise LANs. This type of device provides full control over network traffic, allowing each Ethernet port to be customized individually. This ensures optimal performance in data transmission over the network, leveraging gigabit or 10 gigabit connectivity.<\/div>\n<div><\/div>\n<div style=\"text-align: justify;\">Managed Ethernet Switches allow administrators to configure custom security policies for authentication and authorization as new devices and users are added to the network. End devices or users can be intelligently assigned dedicated or shared bandwidth using advanced QoS, improving overall network efficiency.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">To build virtual local area networks (VLANs, 802.1Q), these switches are tasked with segmenting the network to control broadcast flooding. Additionally, they are designed with Spanning Tree Protocol (STP), ERPS, and OAM capabilities to enable seamless L2 switching in metropolitan and enterprise Ethernet networks.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">&#8211; Unmanaged Ethernet Switches: Unmanaged switches are primarily plug-and-play devices that require minimal installation, typically only an Ethernet cable. The Switch configuration uses auto-negotiation between Ethernet devices, facilitating communication between them.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">Unmanaged switches act like a port multiplier, automatically determining the appropriate data rate, switching between full-duplex and half-duplex modes.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">To access unmanaged switches, administrators need to make physical changes. At the same time, these switches will provide incredible basic network access functionality without any customization. However, they do not provide the flexibility and security of managed switches.<\/div>\n<h3><strong>By function<\/strong><\/h3>\n<div style=\"text-align: justify;\">&#8211; Workgroup Switch: This type of switch is responsible for connecting computers together to form a peer-to-peer network system. This Ethernet Switch does not require large memory or high processing speed.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">&#8211; Segment Switch: This is an Ethernet Switch that connects Workgroup Switches or Hubs together, creating a link at the second layer of the system. This type of switch requires high processing speed.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">&#8211; Backbone Switch: This is a type of switch used to connect segment switching devices together. Backbone Switches require a very large amount of memory and transmission speed to be able to fully contain the addresses of all computer devices in the system. From there, they can promptly convert data between networks.<\/div>\n<h2 style=\"text-align: justify;\"><strong>The Functionality of Ethernet Switch<\/strong><\/h2>\n<div style=\"text-align: justify;\">An Ethernet Switch offers numerous benefits to businesses when installed, integrated, and managed correctly.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">&#8211; Reduces Network Downtime: Minimizes the time that the network is offline.<\/div>\n<div style=\"text-align: justify;\">&#8211; Improves Network Speed and Increases Available Bandwidth**: Enhances the overall speed of the network and provides greater bandwidth.<\/div>\n<div style=\"text-align: justify;\">&#8211; Reduces Load on Personal Computers: Decreases the strain on individual computing devices.<\/div>\n<div style=\"text-align: justify;\">&#8211; Protects Company Networks: Provides stronger security features to safeguard the network.<\/div>\n<div style=\"text-align: justify;\">&#8211; Reduces IT Investment and Operating Costs: Lowers costs through remote management and consolidated cabling systems.<\/div>\n<div style=\"text-align: justify;\">&#8211; Scales IT Infrastructure Appropriately: Facilitates infrastructure sizing and future expansion planning using modular switch devices.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">Most corporate networks support a combination of wired and wireless technologies, with Ethernet switching being a part of the wired infrastructure. Dozens of devices can connect to the network through an Ethernet switch. At the same time, network administrators can monitor traffic, control communication between machines, manage user access securely, and troubleshoot issues quickly.<\/div>\n<div class=\"flex-shrink-0 flex flex-col relative items-end\">\n<div>\n<div class=\"pt-0\">\n<div class=\"gizmo-bot-avatar flex h-8 w-8 items-center justify-center overflow-hidden rounded-full\">\n<h2 class=\"relative p-1 rounded-sm flex items-center justify-center bg-token-main-surface-primary text-token-text-primary h-8 w-8\" style=\"text-align: justify;\"><strong><span style=\"font-size: 20.16px;\">Is Ethernet Different from Wi-Fi?<\/span><\/strong><\/h2>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"group\/conversation-turn relative flex w-full min-w-0 flex-col agent-turn\">\n<div class=\"flex-col gap-1 md:gap-3\">\n<div class=\"flex max-w-full flex-col flex-grow\">\n<div class=\"min-h-[20px] text-message flex w-full flex-col items-end gap-2 break-words [.text-message+&amp;]:mt-5 overflow-x-auto whitespace-normal\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"fe71cbaa-cebd-4e31-94c8-d752b87fab80\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose w-full break-words dark:prose-invert light\">\n<p style=\"text-align: justify;\">Wi-Fi can be considered an extension of the Ethernet access network, enabling wireless connectivity to the Ethernet network. With Wi-Fi, users can move freely without needing a wired network connection.<\/p>\n<p style=\"text-align: justify;\">Typically, Wi-Fi requires a wireless access point to serve as the interface with the network. End devices connect to the access point, which in turn is connected to a part of the Ethernet switch rather than connecting directly to the switch via physical cables.<\/p>\n<p style=\"text-align: justify;\">Wi-Fi and Ethernet differ in their IEEE 802 protocols. Ethernet is defined by IEEE 802.3, while Wi-Fi is defined by IEEE 802.11.<\/p>\n<p style=\"text-align: justify;\">From a user\u2019s perspective, Ethernet connections require physical cables and provide a dedicated link from the switch to the end device with bandwidth up to the speed of the connected port. Wi-Fi connections, on the other hand, are wireless and allow devices to receive Wi-Fi signals from anywhere within range. However, they require sharing the bandwidth of the Wi-Fi access point with other devices connected to the same AP.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-9542 size-full\" title=\"Kh\u00e1c bi\u1ec7t gi\u1eefa k\u1ebft n\u1ed1i Ethernet v\u00e0 Wifi\" src=\"https:\/\/dngcorp.vn\/wp-content\/uploads\/2024\/05\/ethernet-switch-3.jpg\" alt=\"What is Ethernet Switch?\" width=\"800\" height=\"500\" \/><\/p>\n<p style=\"text-align: center;\"><em>Difference between Ethernet and Wifi connection<\/em><\/p>\n<h2><strong>Managed and Unmanaged Ethernet Switches<\/strong><\/h2>\n<p><strong>Unmanaged Ethernet Switches<\/strong> refer to switches that come with no user configuration options; these devices simply need to be plugged in and turned on.<\/p>\n<p><strong>Managed Ethernet Switches<\/strong> are switches that can be managed and programmed to deliver specific results and perform certain tasks.
