Modem vs router firewalls full#
With switches, the bandwidth does not have to be shared and all ports operate at full speed. The more devices on a hub, the more bandwidth that has to be shared and therefore the network gets slower. This is also why a hub is a half-duplex device whereas a switch is a full-duplex device. The bandwidth is not shared with other ports. With switches, there are zero collisions because only the two devices that are communicating will be sending data back and forth. This happens on hubs a lot because all the traffic coming in on each port is repeated out to all the other ports. Collisions means when two computers or devices send data at the same time and the signals physically collide before reaching the destination. With hubs, the more devices you connect to the hub, the more collisions there will be on the network. This significantly reduces the amount of traffic on the network because there is direct communication between the two devices rather than a one-to-all type of communication.

Instead of blindly forwarding all the frames it receives on one port to all the other ports on the device, a switch will create a MAC address source table and then forward the frame to the port with the correct destination MAC address. The part of the frame that contains the source/destination IP addresses is called a packet. Don’t worry about the technical details, just know that it contains source and destination MAC addresses and source and destination IP addresses inside the frame. The Data Link layer of the OSI model deals with MAC addresses and switches look at MAC addresses when they process an incoming frame on a port.Ī frame is a data type that is used to carry data on all networking devices. Hubs are considered Layer 1 (Physical) devices whereas switches are put into Layer 2 (Data Link). You connect devices to a hub using Ethernet cable and any signal sent from a device to the hub is simply repeated out on all other ports connected to the hub. It looks just like a switch, but works differently on the inside. Switches vs HubsĪ hub is an obsolete device that you would never want to buy these days. Finally, we’ll talk about modems and other networking terms like access points and gateways. Next, we’ll talk about routers and why they are different than switches and hubs. First, I’ll talk about the difference between switches and hubs, as both of those devices are in the same category. Both are important for creating and maintaining a home network, and they often work together to provide internet access to all of your devices.In this article, I’ll try to explain the concept behind each of these terms without getting too technical. To conclude, a modem is a device that connects you to the internet, while a router is a device that connects multiple wired or wireless devices to a single internet connection. Some routers even include built-in modems, allowing you to connect directly to your ISP without needing a separate modem. Routers come in various shapes and sizes, and they offer a range of features, such as wireless connectivity, firewalls, and advanced security protocols. Routers are often used in homes and small businesses to create a local area network (LAN) that allows multiple devices to share a single internet connection. It does this by "routing" data between devices on your home network and the internet. They are commonly used in areas where other types of internet service are not available.Ī router is a device that connects multiple devices to a single internet connection.
Cable modems: These modems use a coaxial cable to connect to the internet.There are different types of modems, including: Modems are essential for connecting to the internet, as they provide the necessary link between your device and your internet service provider (ISP). It does this by converting the digital data that your computer or device sends and receives into analog signals that can be transmitted over a phone line or cable connection. What is a modem, and what does it do?Ī modem is a device that allows you to connect to the internet. But do you know what these devices actually do and how they differ from each other? In this post, we'll explore the key differences between modems and routers so you can better understand how they work and fit into your home network. If you're setting up a home network, you've probably heard the terms "modem" and "router" thrown around a lot.
