Which of the following are Physical Layer 1 components? Choose three.Choose all applicable answers.ServersHubsJacksCables

1. Break Down the Problem

To determine which components belong to Physical Layer 1, we need to analyze each option provided: Servers, Hubs, Jacks, and Cables.

2. Relevant Concepts

• Physical Layer 1: This layer of the OSI model is responsible for the physical connection between devices. It includes the actual hardware and physical medium through which data is transmitted.

3. Analysis and Detail

1. Servers: These are considered higher-level components that operate above the physical layer; thus, they are not part of Layer 1.
2. Hubs: These are networking devices that connect multiple Ethernet devices, making them part of the physical layer since they deal directly with data transmission.
3. Jacks: Connectivity points that allow network cables to connect, these also fall under Layer 1 as they facilitate the physical connection.
4. Cables: Cables are physical media for transmitting data; they are an integral part of the physical layer.

4. Verify and Summarize

After analyzing each component, we identify that Hubs, Jacks, and Cables all function as Physical Layer 1 components.

Final Answer

The three Physical Layer 1 components are: Hubs, Jacks, and Cables.
