Mode Of Connection - Wired Vs Wireless Network

Multiple Choice

What is Ethernet primarily used for?

• Connecting devices in a local area network (LAN)
• Providing wireless connectivity to devices
• Connecting devices over the internet
• Transmitting data over long distances

Multiple Choice

Which type of cable is commonly used in Ethernet connections?

• Coaxial cable
• Twisted pair cable (Cat 5e or Cat 6)
• Fiber optic cable
• HDMI cable

Multiple Choice

What does duplex communication mean in Ethernet?

• Sending and receiving data at different times

• Only sending data without receiving.

• Sending and receiving data simultaneously

• Duplex communication refers to the speed of data transmission.

Multiple Choice

What older protocol was used to detect collisions in Ethernet?

• CSMA/CA
• Token Ring
• CSMA/CD
• Aloha

Multiple Choice

Why is CSMA/CD no longer required in modern Ethernet?

• Modern Ethernet uses switches that prevent collisions.

• Modern Ethernet relies on wireless connections that require CSMA/CD.
• CSMA/CD is still used in all Ethernet networks.
• Switches are not capable of preventing collisions in Ethernet.

Multiple Choice

What is the purpose of the preamble in an Ethernet frame?

• To provide error correction for data transmission.
• To define the maximum frame size allowed.
• To encrypt the data within the frame.
• To synchronise communication between sender and receiver.

Multiple Choice

What does the Start Frame Delimiter indicate?

• It indicates the beginning of a frame in data communication.

• Marks the end of a frame in data communication.

• Is used to identify the type of data being transmitted.

• The Start Frame Delimiter indicates the speed of data transmission.

Multiple Choice

Which address identifies where the Ethernet frame is going?

• IP address
• Source MAC address
• Port number
• Destination MAC address

Multiple Choice

What type of data is included in the Ethernet frame?

• Actual user data

• TCP header
• IP address

Multiple Choice

What is used for error checking in an Ethernet frame?

• CRC (Cyclic Redundancy Check)

• MAC address

• Firewalls

• SSL Certificate

Multiple Choice
