What is the connectivity device that transmits packets the fastest between two computers?

• A. Router
• B. Switch
• C. Network Bridge
• D. Hub

Answer: (C)

The correct choice for the connectivity device that transmits packets the fastest between two computers is the switch. A switch operates at the data link layer (Layer 2) of the OSI model and is designed to forward data packets directly to the correct destination device within a network. When a packet arrives at a switch, it examines the MAC address and sends the packet only to the specific device that needs it, thereby minimizing unnecessary traffic. This targeted approach leads to faster and more efficient data transmission between computers connected to the same local area network (LAN). In contrast, devices like routers and hubs operate in different ways. Routers connect multiple networks together and examine IP addresses, making routing decisions based on that information, which can introduce latency. A hub merely broadcasts incoming packets to all devices on a network without distinction, resulting in inefficient use of bandwidth and slower overall network performance. Network bridges, while also helping to segment networks and reduce traffic, do not perform as efficiently as switches in transmitting packets directly to the intended recipient. Thus, in terms of speed and efficiency in transmitting packets between two computers, a switch outperforms the other connectivity devices listed.
