Explanation

Transmission media refers to the physical path (like cables or wireless signals) used to transfer data between devices.

It enables communication in computer networks, such as LANs and the Internet.

Explanation

The Data Link layer is responsible for physical addressing through MAC (Media Access Control) addresses.

The Physical layer deals with transmitting raw bits over the medium.

Explanation

Networks are typically classified into four main types based on distance (geographical coverage):

1. PAN (Personal Area Network) – Very short distance (e.g., Bluetooth, USB connections).
2. LAN (Local Area Network) – Limited area (e.g., home, office, or school network).
3. MAN (Metropolitan Area Network) – City-wide coverage (e.g., ISP networks in a city).
4. WAN (Wide Area Network) – Large-scale, global reach (e.g., the Internet).

Explanation

A switch operates at the Data Link Layer (Layer 2) of the OSI model.

It uses MAC addresses to forward data frames within a local network.

Explanation

A gateway is a device that connects two or more networks using different communication protocols.

It acts as a translator between systems so they can communicate effectively.

Explanation

A switch connects two or more computers within the same local area network (LAN).

It intelligently forwards data only to the specific device intended, improving network efficiency.
