A network switch is a hardware device used to connect multiple devices on a computer network. A switch can be managed locally or remotely through a console port, Telnet connection, or web interface. Switches make it possible for multiple computers to share resources on a network. Layer 2 switches are designed to forward data packets based on their MAC addresses (Media Access Control) while layer 3 switches perform IP routing between networks and different subnets. The bridge function of layer 2 switches allows them to act as bridges or repeaters for Ethernet networks and as hubs for Fast Ethernet or Gigabit Ethernet networks
The first thing to keep in mind is the difference between LAN and WAN.
The first thing to keep in mind is the difference between LAN and WAN. A LAN is a Local Area Network, or a network of computers and other devices within a small area, such as a home or office. A WAN is a Wide Area Network, which means it’s spread over a large area that can be anything from across town to across continents.

A switch is actually a small computer, built to handle switching traffic. Switches are faster than routers because they don’t have to process routing information. They also use less power and cost less than routers, so they’re ideal for small networks with few users.

- Local management is done through a console port. The user needs to connect the computer directly to the switch and use it as an input device. This method is used when you have only one or two switches on your network, but as you add more switches and devices they will become harder to manage individually in this manner.
- Remote management is done through a Telnet connection (or other type of remote access software). This method allows you to connect using any device with an internet connection and control all devices connected within your network remotely without having physical access to them physically in person at all times which would be impossible due to their size being very large compared against laptops/desktops etcetera so this form could only work if someone wanted too badly enough!
Switches make it possible for multiple computers to share resources on a network.
Switches are used to connect multiple devices on a network. They allow users to share resources such as printers and files, and they allow computers to communicate with each other. Switches can also be used to connect networks together, or connect networks to the internet.
Layer 2 switches are designed to forward data packets based on their MAC addresses.
Layer 2 switches are designed to forward data packets based on their MAC addresses. A MAC address is a 48-bit number that is unique to each device on a network, and it’s stored in the MAC address table of the switch. When you send data across your network, each switch looks at its own table and forwards your packet based on what port it thinks should be receiving that packet (based on its destination IP address).
Layer 3 switches, also known as routers, perform IP routing between networks and different subnets.
Layer 3 switches, also known as routers, perform IP routing between networks and different subnets. They support IP and IPX routing protocols and can be used to connect multiple networks together. Layer 3 switches can also be used to connect networks of different technologies together or networks of different sizes together.
The bridge function of layer 2 switches allows them to act as bridges or repeaters for Ethernet networks and as hubs for Fast Ethernet or Gigabit Ethernet networks.
The bridge function of layer 2 switches allows them to act as bridges or repeaters for Ethernet networks and as hubs for Fast Ethernet or Gigabit Ethernet networks. A bridging device works by “listening” to the traffic on each network and forwarding it only when the destination address matches a MAC address in its table. This is different from routing, which involves sending packets based on their source IP addresses rather than their MAC addresses.
Switches come in many different types and perform various functions
Switches come in many different types and perform various functions.
- Switches are used to improve the performance of a network by allowing you to connect multiple hosts together, while still maintaining full bandwidth between them. For example, if you need more than one computer on your network but don’t want them sharing each other’s resources (such as printers), using a switch instead of an ordinary hub will allow each computer its own dedicated connection to the Internet without affecting any others’ ability to send data packets through the same cable–thus maximizing throughput and reducing latency issues that might otherwise occur when two hosts try sending information through one hub at once.
- Switches can also be used for managing traffic on your local area network (LAN). This can be done locally or remotely through a console port, Telnet connection, or web interface depending on what kind of switch model you choose; however most people prefer remote management options because they make it simpler for IT professionals who manage large networks consisting of hundreds or even thousands upon thousands
Switches are an essential part of any network. They provide a way for computers and other devices on a network to communicate with each other, share resources such as printers and files, and connect to the Internet. The type of switch you choose will depend on what kind of traffic needs to be routed through it–LAN or WAN traffic–as well as how many ports are needed.
