CompTIA A+ Certification Core 1 (220-1101) - TCP, UDP, and ICMP

The video tutorial explains the concept of protocols, focusing on TCP/IP, UDP, and ICMP. It uses analogies to illustrate how these protocols facilitate internet communication. The tutorial also introduces Protocol Data Units (PDUs) and their significance in data transmission, highlighting the differences between Ethernet frames, IP packets, and TCP segments.

What is the primary role of a protocol in networking?

• To manage power consumption in devices

• To encrypt data for security

• To establish a set of rules for communication

• To provide a physical connection between devices

Which protocol is known for establishing a connection before data transfer?

• IP

• UDP

• ICMP

• TCP

In the ice cream shop analogy, what does the handshake represent in TCP?

• Establishing a connection

• Paying for the ice cream

• Leaving the shop

• Ordering ice cream

How does UDP differ from TCP in terms of connection?

• UDP requires a handshake

• UDP is slower than TCP

• UDP encrypts data

• UDP is connectionless

What is a unique feature of the ICMP protocol?

• It always uses a single packet

• It uses multiple packets

• It requires a handshake

• It is used for streaming video

What does PDU stand for in networking?

• Protocol Data Unit

• Packet Data Utility

• Protocol Delivery Unit

• Packet Delivery Utility

Which of the following is NOT a type of PDU mentioned?

• TCP segment

• UDP packet

• IP packet

• Ethernet frame
