1. How do switches affect network performance?
- The switch's processor, which manages the data flowing through the switch, can also affect overall performance, as can the switch's internal memory.
- Latency – which affects the time from a request until when a user sees a result – is another element of performance that is affected by the switch.

2. Why are switches important in networking?
- Switches are key building blocks for any network.
- They connect multiple devices, such as computers, wireless access points, printers, and servers, on the same network within a building or campus.
- A switch enables connected devices to share information and talk to each other.

3. How do switches manage network data?
- Multiple data cables are plugged into a switch to enable communication between different networked devices.
- Switches manage the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended.

4. Do network switches have different speeds?
- Switches also vary in the network speed they offer, ranging from Fast Ethernet (10/100 Mbps), Gigabit Ethernet (10/100/1000 Mbps), 10 Gigabit (10/100/1000/10000 Mbps) and even 40/100 Gbps speeds.
- The choice of speeds depends on the throughput needed for the tasks being supported.

5. Do network switches need power?
- All network switches need the power to operate. Most network switches consist of AC power.
- Thus, it is essential to have a power source outlet when running an Ethernet switch.
- Ethernet switches will need the power to operate like any other network switches.
6. Does a switch have an IP address?
- Network switches can have IP Addresses depending on whether they are Layer 3 Switches.
- In production, if a Switch has an IP Address, it needs to be a static address for the purposes of monitoring and re-configuration

7. How many ports can a switch have?
- Fixed-configuration switches are usually available with five, eight, 10, 16, 24, 28, 48, or 52 ports.
Reference
8. Do network switches need cooling?
- This is because there are a ton of connectivity requirements between a large number of servers across various tiers.
- Because of this, it's important to know how to maintain your network switches, which involves cooling them, so they don't overheat.
Reference
9. Do network switches store data?
- Switches have three primary tasks.
- They learn MAC addresses, forward data packets, and protect those packets.
- Switches learn and store MAC addresses in what's called the Content Addressable Memory (CAM) table, a type of LUT. Some switches can forward data through Layer 3 network overlays using IP address parameters.
Reference
10. Does network switch an end device?
- A source or destination device in a networked system.
- For example, a user's PC is an end device, and so is a server.
- Network switches, routers and other equipment work in between to enable messages to travel from one end device to the other.
Reference
11. Are network switches wired?
- Network switches are often referred to as an ethernet switch or LAN switch (Local Area Network).
- The latter name reflects the fact that they typically rely on cabled connections to support networking activities across a relatively limited physical space, such as a single office.
