If you want to create a huge local network, you will have to resort to a switch or a network hub , which is specially designed to add more LAN ports to the switch. The WAN port is located on the back of the router used to connect with your modem to access the Internet from the ISP provider in order to take advantage of the internet on all the devices associated with it.
In any router, the WAN port is always separate from the LAN ports and often comes in a different color so that it can be recognized. In general, a router has only one WAN port. Some with dual WAN ports for enterprises, so one can use them to connect two different modems , usually from different Internet providers simultaneously. The router asserts the unique public IP address your Internet Service Provider assigns to you and it offers security features such as a firewall with port forwarding and quality of service, which prioritizes Internet traffic.
WAN port is used to connect with a modem for Internet source while LAN port is utilized to share that Internet connection with all devices associated to routers such as a computer, printer, and mobile phones.
The user needs to know what is the difference between these ports while connecting a home router to the Internet. Remember that a LAN socket is needed to connect computers if there are several, and the WAN is needed to connect with the modem which allows you to receive a signal from the Internet provider. Also, the ports differ in the data transfer rate. The speed of data transfer in a local network is often higher than the speed of downloading data from the Internet.
This can be both because of a limitation in the levy plan from the provider, and due to the limitations of the connector itself. Therefore, devices can exchange data via Wi-Fi with each other at a high speed, provided that the network cards of the devices support this speed. LAN port is used to provide Internet access or files sharing facility to all the connected devices. WAN port is used to provide Internet access by connecting with a modem or wireless broadband to all the connected routers.
Networking Devices. Wi-Fi, access point, router, But it doesn't have to be if you know what you're doing. This is where you start. If you're having a hard time with these basic terms, you're reading the right post.
Here I'll try to explain them all so that you can have a better understanding of your home network and hopefully a better control of your online life. There's a lot to explain so this long post is just the first of an evolving series. Advanced and experienced users likely won't need this, but for the rest, I'd recommend reading the whole thing.
So take your time, but in case you want to jump to a quick answer, feel free to search for what you want to know and chances are you will find it within this post. A wired local network is basically a group of devices connected to one another using network cables, more often than not with the help of a router , which brings us to the very first thing you should know about your network.
Router: This is the central device of a home network into which you can plug one end of a network cable. The other end of the cable goes into a networking device that has a network port. If you want to add more network devices to a router, you'll need more cables and more ports on the router. They are also known as RJ45 ports or Ethernet ports. The moment you plug a device into a router, you have yourself a wired network. Networking devices that come with an RJ45 network port are called Ethernet-ready devices.
More on this below. Note : Technically, you can skip the router and connect two computers directly together using one network cable to form a network of two. However, this requires manually configuring the IP addresses, or using a special crossover cable , for the connection to work. You don't really want to do that. LAN ports: A home router usually has four LAN ports, meaning that, straight out of the box, it can host a network of up to four wired networking devices. If you want to have a larger network, you will need to resort to a switch or a hub , which adds more LAN ports to the router.
Generally a home router can connect up to about networking devices, and the majority of homes and even small businesses don't need more than that. There are currently two main speed standards for LAN ports: Ethernet also called Fast Ethernet, which caps at megabits per second or about 13 megabytes per second , and Gigabit Ethernet, which caps at 1 gigabit per second or about MBps.
In other words, it takes about a minute to transfer a CD's worth of data around MB or about digital songs over an Ethernet connection. With Gigabit Ethernet, the same job takes about five seconds. In real life, the average speed of an Ethernet connection is about 8 MBps, and of a Gigabit Ethernet connection is somewhere between 45 and MBps. The actual speed of a network connection depends on many factors, such as the end devices being used, the quality of the cable and the amount of traffic.
Rule of thumb : The speed of a single network connection is determined by the slowest speed of any party involved. For example, in order to have a wired Gigabit Ethernet connection between two computers, both computers, the router they are connected to and the cables used to link them together all need to support Gigabit Ethernet or a faster standard.
If you plug a Gigabit Ethernet device and an regular Ethernet device into a router, the connection between the two will be capped at the speed of Ethernet, which is Mbps. In short, LAN ports on a router allow Ethernet-ready devices to connect to one another and share data. On many routers, this port may also be labeled the i nternet port.
Switch vs. They help increase the number of Ethernet-ready clients that a network can host. The main difference between hubs and switches is a hub uses one shared channel for all of its ports, while a switch has a dedicated channel for each one. This means the more clients you connect to a hub, the slower the data rate gets for each client, whereas with a switch the speed doesn't change according to the number of connected clients.
For this reason, hubs are much cheaper than switches with the same number of ports. However, hubs are largely obsolete now, since the cost of switches has come down significantly.
The price of a switch generally varies based on its standard regular Ethernet or Gigabit Ethernet, with the latter being more expensive , and the number of ports the more ports, the higher the price.
You can find a switch with just four or up to 48 ports or even more. Note that the total of extra wired clients you can add to a network is equal to the switch's total number of ports minus one. For example, a four-port switch will add another three clients to the network. This is because you need to use one of the ports to connect the switch itself to the network, which, by the way, also uses another port of the existing network.
With this in mind, make sure you buy a switch with significantly more ports than the number of clients you intend to add to the network. Wide-area network WAN port: Also known as the internet port. Generally, a router has just one WAN port. Some business routers come with dual WAN ports, so one can use two separate internet services at a time.
On any router, the WAN port will be separated from the LAN ports, and is often distinguished by being a different color. A WAN port is used to connect to an internet source, such as a broadband modem. WANs can be as large as a state, a country, or the world. The Internet itself is a type of WAN, because it covers the entire globe.
Although a network connecting LANs in the same city, like a group of offices belonging to the same company, these are usually called metropolitan area networks. A computer network simply means any set of computers and other devices like smartphones, smart TVs, video game systems and routers that are able to communicate back and forth with each other. Different protocols, or rule systems, exist that let computers understand each other and transmit data.
A LAN, or local area network, is a small network, often within a home or business or perhaps within a larger environment like a corporate office park or a college campus. A LAN can use wireless communication, wired connections or both. A LAN, or local area network, is a small network, often within a home or business or perhaps within a larger environment like a corporate office park or a college campus.
Devices on a LAN often use the LAN's infrastructure to connect to the public internet, but they can often communicate with each other directly through the LAN more quickly. For instance, it's not usually necessary to send a file to the public internet in order to get it to a printer on the same LAN.
A LAN can use wireless communication, wired connections or both. A wide area network usually traverses multiple geographical areas.
