CompTIA A+ 1101 TCP and UDP

Question 1

• transported inside of an IP packet
• encapsulated by the IP protocol
• two very common ways to move data from place to place
• operate at OSI layer 4, the transport layer
• add additional capabilities that IP, alone, can’t provide, such as multiplexing (use many different applications at the same time)

Answer 1

TCP and UDP

Question 2

Transmission Control Protocol

Answer 2

TCP (Acronym)

Question 3

User Datagram Protocol

Answer 3

UDP (Acronym)

Question 4

• connection-orientated protocol
• uses a three-way handshake to establish a reliable connection, making it a reliable protocol (has a built in system to verify receipt of data, can recover from errors, and can manage out-out-order messages or retransmissions)
• utilizes flow control (the receiver can manage how much data is sent)

Answer 4

TCP

Question 5

• connectionless protocol
• real-time communication (no way to stop and resend data)
• unreliable delivery
• no flow control (the sender determines how much data is transmitted)

Answer 5

UDP
