(Part 4) Network Model

What does the TCP/IP protocol suite define?

• How to build a computer network

• How to design a website

• How to create a mobile app

• How transmissions are exchanged across the Internet

How many layers are there in the original TCP/IP protocol suite?

• Six

• Five

• Four

• Three

Which layer in the TCP/IP protocol suite handles high-level protocols and issues of representation, encoding, and dialog control?

• Network Layer

• Physical Layer

• Transport Layer

• Application Layer

Which protocol is included in the Transport Layer of the TCP/IP protocol suite?

• Stream Control Transmission Protocol (SCTP)

• User Datagram Protocol (UDP)

• Host-to-Network Protocol

• Internet Protocol (IP)

What is the main function of the Internet Layer in the TCP/IP protocol suite?

• End-to-end data delivery

• Best path determination and packet switching

• Quality-of-service issues

• Physical medium connection

What is the purpose of the Network Access Layer in the TCP/IP protocol suite?

• End-to-end data delivery

• Best path determination and packet switching

• Quality-of-service issues

• Physical medium connection

How many layers does the TCP/IP protocol suite have when compared to the OSI model?

• Five

• Four

• Three

• Six

What is a similarity between the OSI and TCP/IP models?

• TCP/IP combines the presentation and session layer issues into its application layer

• TCP/IP combines the data link and physical layers into one layer

• TCP/IP appears simpler because it has fewer layers

• TCP/IP protocols are not the standards around which the Internet developed

What is a difference between the OSI and TCP/IP models?

• TCP/IP involves 3 different types of addressing

• TCP/IP involves 5 different types of addressing

• TCP/IP involves 4 different types of addressing

• TCP/IP involves 6 different types of addressing

What type of address is used in the TCP/IP protocol suite for making a connection to the physical medium?

• Specific Address

• Port Address

• Logical Address

• Physical Address
