Ethernet Splitter vs Switch vs Modem vs Bridge



This post will cover important information about network switches, modems, splitters, and bridges. You'll learn about the definitions of Gigabit switches, how they operate, and the differences between the best Ethernet switch vs modem vs splitter vs bridge.

In your installation, there are various network devices such as switches, modems, splitters, bridges, and potentially more. You may be familiar with some of them and confused about choosing the best Ethernet switch or Gigabit switch. Do you genuinely understand their differences? This article aims to clarify what these devices are and how they differ from one another. 


What are Switches, Modems, Splitters, and Bridges


Network Switch


A network switch serves as an essential hardware device in networking, facilitating efficient communication between interconnected devices. Its primary function involves receiving data packets and intelligently directing them to their intended destinations. This ensures that the data is sent only to the specific computers or devices it intends to, optimizing network efficiency and reducing unnecessary traffic. To learn more about network switches, including comprehensive guides and selection assistance, you can refer to What is a Network Switch, and How Does It Work? Which provides detailed information and resources on this important networking component.






The modem, often called a "modulator, demodulator," is a compact network device that empowers your network equipment to effectively transmit and receive signals over a telephone line or cable originating from outside your residence.


The primary function of a modem is to establish a connection with your Internet Service Provider (ISP) to facilitate Internet access. While it allows a wired device to connect, if you have multiple devices and desire wireless connectivity, you will require a router in addition to the modem to use the WiFi function. Upon subscribing to ISP services, they typically provide you with a modem compatible with the specific type of internet service you receive. If you decide to purchase your own modem, it is essential to ensure that your ISP recommends or approves the models you select.




Ethernet Splitter


The splitter, a compact and convenient device, is ingeniously equipped with three Ethernet ports—two on one side and one on the other. It is specifically designed to seamlessly comply with the older 100BASE-T standard. With this smart design, each pair of Ethernet splitters can effortlessly accommodate two cables. By harnessing the capabilities of a network splitter, it becomes possible to effectively divide a single Internet connection, thereby facilitating the creation of additional connections. This convenient functionality allows for the sharing of a single Ethernet signal between two devices, significantly reducing the requirement for multiple Cat5 cables when connecting two networks.


Network Bridge


A bridge, commonly referred to as a network bridge or Ethernet bridge, serves as an essential network node responsible for establishing connectivity between two networks that utilize different protocols. Its core purpose is to establish a connection between a local area network (LAN) and another LAN operating on the same protocol. Operating as both an entry and exit point for a network, a bridge holds significant importance in dividing networks into manageable segments, thus facilitating efficient communication.


The Difference Between Switch vs Modem vs Splitter vs Bridge


Switch vs Modem


A network switch and modem are distinct devices with different functions in computer networking. A switch connects multiple devices within a local network, enabling efficient and simultaneous data transmission at the data link layer. A modem establishes a connection between a computer or local network and an internet service provider (ISP) network by modulating digital signals for transmission and demodulating received analog signals back into digital format. While switches facilitate communication within a network, modems provide internet access by connecting the local network or computer to the wider internet through the ISP network. These devices typically have ports, power inputs, and status LEDs. They are often interconnected through a router, which links the modem to the ISP and connects the switch to the local network. 


Switches are commonly used in extensive networks like enterprises, campuses, and data centers, while modems primarily serve the purpose of internet connectivity for home networks. It's worth noting the significant differences in their configuration options.


Switch vs Bridge


A bridge is a network device that connects two network segments, similar to data link switches. Both bridges and switches enhance network performance, reliability, and security. Routers and computers can also function as bridges. While switches typically have numerous ports, bridges usually have two or four ports, limiting their connectivity. In contrast, switches can have many ports, allowing for larger network expansion and the ability to connect multiple networks. Additionally, switches offer advanced features like VLAN support and QoS capabilities. 


In summary, bridges are simpler devices used to connect a few segments, while switches are better in function, port capacity, and network expansion

 and can handle larger network deployments with multiple segments.


Switch vs Ethernet Splitter


A switch is an intelligent device that processes and forwards data packets, enabling simultaneous communication among multiple devices within a network. It provides advanced features like VLAN support and port management. An Ethernet splitter, also known as a hub, is a passive device that divides an Ethernet connection into multiple separate connections. It lacks the processing capabilities and advanced functionality of a switch. Switches typically have multiple ports, offering dedicated bandwidth to each device, while Ethernet splitters have a limited number of ports and share available bandwidth among connected devices. Consequently, Ethernet splitters may result in decreased performance and potential collisions during simultaneous data transmission. 


In summary, switches outperform Ethernet splitters in terms of performance, efficiency, and advanced functionality. While switches can be used individually or in groups, Ethernet splitters require pairing and do not require power input. Ethernet splitters are a simpler solution that is more suitable for basic network setups.
