What does Ethernet provide between two points on a network?

• Wireless Communication

• Unreliable Communication

• Optical Communication

• Reliable, Error-Free Communication

Answer explanation

Ethernet provides reliable, error-free communication between two points on a network, ensuring data transmission with minimal errors or loss.

What is used in Ethernet to ensure the destination computer knows if the transmission was successful?

• IP Addressing

• Cyclic Redundancy Check

• MAC Address

• Preamble of Bits

Answer explanation

Cyclic Redundancy Check is used in Ethernet to ensure the destination computer knows if the transmission was successful.

What type of network allows duplex communication in Ethernet?

• Bus Network

• Star Network

• Mesh Network

• Ring Network

Answer explanation

In Ethernet, a Star Network allows duplex communication as it uses a central hub to connect all devices, enabling simultaneous two-way communication.

What is a common standard for wireless networks?

• Bluetooth

• Wi-Fi

• Ethernet

• NFC

Answer explanation

Wi-Fi is a common standard for wireless networks, providing high-speed internet access to devices within a specific range. Bluetooth, Ethernet, and NFC are also wireless technologies but serve different purposes.
