A gigabit switch connects multiple devices to a LAN and allows for faster data transfer than standard Ethernet. It should be distinguished from a hub and used with other compatible devices and fast internet speeds. CAT6 cables are recommended for optimal performance.
In computer networks, an Ethernet switch connects multiple devices, such as computers, servers, or gaming systems, to a local area network (LAN). Small businesses and home offices often use such a switch to allow more than one device to share a broadband Internet connection. A gigabit switch works the same way, only at data rates much higher than standard or Fast Ethernet. People can use these switches to quickly transfer data between devices in a network or to download it from the internet at very high speeds.
Scope
Broadband Internet connections for audio and video streaming have increased the demand for faster and more stable transmissions. Gigabit Ethernet transmits at approximately one gigabit per second. That’s at speeds nearly 100 times that of Fast Ethernet, which transfers data at about 10 megabits per second. The gigabit switch is designed to operate at these higher speeds, with no signal loss or reduction in transfer speed.
Difference between a switch and a hub
When purchasing a gigabit switch, it is important to ensure that the item you are purchasing is truly a switch and not a hub. An Ethernet switch and a hub are similar in function, but operate quite differently. The main feature that distinguishes the switch is that each connection to it has its own dedicated bandwidth and does not share transmission lines with other connected devices; this is called “Full Duplex”. This results in less data collision and faster, more reliable communication speeds than hubs that share bandwidth between connected devices.
Functionality with other devices
A gigabit switch can be used in conjunction with other network devices. Broadband modems, such as those used with Digital Subscriber Line (DSL) or cable Internet services, have only one wired connection. Users can install a gigabit switch together with a modem to enable multiple connections or to create a local area network between several devices. While these switches were initially quite expensive, they have become increasingly available for use in home offices and entertainment setups.
Correct configuration
When configuring a Gigabit Ethernet network, users should ensure that all components are designed for fast Gigabit speeds. Using a slower modem can reduce transfer speeds, even if your other network devices, such as a computer and gigabit switch, are designed for gigabit speeds. People installing this type of system should also ensure they have the fastest internet speeds available from their service providers.
Typically, Category 6 (CAT6) Ethernet cable is best for connecting other network devices or computers to a gigabit switch. Category 5 (CAT5) cabling is only rated for Fast Ethernet or 10 megabits per second. People can use some Category 5E (CAT5E) Ethernet cables to connect to a gigabit switch, but they are often less reliable than CAT6 cables.
