What would you typically expect from a switch in a networking context?

A switch is a fundamental component in networking, primarily designed to connect multiple devices within the same local area network (LAN). Its main function is to receive incoming data packets from one device and forward them to the intended destination device on the network. This process is efficient because switches operate at the data link layer (Layer 2) and make decisions based on MAC addresses, allowing multiple devices to communicate with each other seamlessly.

In contrast, a firewall is typically responsible for monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. This is a different function and not the primary role of a switch.

While some high-end switches may include features for temporary data storage or buffering, they do not store all data for the network; that function is more characteristic of a server or storage device.

Providing internet access is also not a direct function of a switch. Instead, this is typically the role of a router, which connects different networks and routes traffic between them, including connecting to the internet.

Therefore, the primary expectation from a switch in a networking context is its ability to connect devices and facilitate communication between them, making it a critical element in most network configurations.
