Chapter 1 Introduction to TCP/IP Networking ANSWERS INCLUDED
1) In the TCP/IP model, which layer defines the interface between software running on the
computer and the network itself?
A) Transport
B) Internet
C) Application
D) Data link
M
Answer: C
Explanation: A) The transport layer is incorrect because it deals with data delivery and flow
ED
control.
B) The Internet layer is incorrect because it deals with addressing and routing.
C) Application is correct because the application layer protocols provide services to the
application software. The application layer does not define the application itself but does define
C
how the application can access the network.
D) The data link layer is incorrect because it deals with how to access media.
O
2) Which layer of the TCP/IP model defines the rules for data packet recovery?
N
A) Transport
B) Internet
N
C) Application
D) Data link
O
Answer: A
Explanation: A) Transport is correct because the transport layer protocols deal with error
IS
recovery of data. The transport layer also handles the mechanism to guarantee delivery across the
network. The other layers do not.

3) What are the two main services provided by the network layer of the TCP/IP model?
A) Compression
U
B) Addressing
C) Routing
R
D) Reliability
E) Encryption
Answer: B, C
Explanation: B) Addressing and routing are correct answers because addressing deals with
placing the correct IP address in the packet, and routing deals with getting the packet to the
correct destination.
C) Addressing and routing are correct answers because addressing deals with placing the correct
IP address in the packet, and routing deals with getting the packet to the correct destination.

,4) The process of forwarding an IP packet from host to host is known as .
A) Delivery
B) Switching
C) Routing
D) Sending
Answer: C
Explanation: C) Routing is the correct answer because routing deals with getting the packet to
the correct destination. Switching deals with getting frames to their correct destinations. Routing
works much like the postal service to deliver messages to the correct destination.

5) What name is given to the process of enclosing data with headers and trailers as the data is
moved down the TCP/IP model?
ED
A) Condensing
B) Inclosing
C) Encryption
D) Encapsulation
C
Answer: D
Explanation: D) Encapsulation is the correct answer because as the data moves down the
O
TCP/IP model and each layer attaches its control data, this process is known as encapsulation.

6) Which layer of the OSI model defines how to start, control, and end conversations by
grouping messages in a workflow?
N
A) Application layer
B) Presentation layer
O
C) Session layer
D) Transport layer
IS
E) Network layer
F) Data link layer
G) Physical layer
SE
Answer: C
Explanation: C) The session layer defines the start, control, and end of conversations (called
session) with each computer.

,7) Which layer of the OSI model defines functions related to data delivery, error recovery, and
flow control?
A) Application layer
B) Presentation layer
C) Session layer
D) Transport layer
E) Network layer
F) Data link layer
G) Physical layer
Answer: D
Explanation: D) The transport layer focuses on issues related to data delivery to another
M
computer (for example, error recovery and flow control).

8) Which layer of the OSI model provides an interface between the network and the software
running on a host machine?
A) Application layer
B) Presentation layer
C
C) Session layer
D) Transport layer
O
E) Network layer
F) Data link layer
N
G) Physical layer
Answer: A
N
Explanation: A) The application layer focuses on issues related to communication between the
software and the network.

9) In IT, what term refers to a small network that is used for business purposes, typically in the
home of a business or employee?
A) Organizational network
SE
B) Enterprise network
C) IT network
D) SOHO network
U
E) Cloud network
Answer: D
R
Explanation: D) When you start to work in a new industry, it is good to be familiar with some of
the most popularly used terms. When referring to a small network that is used for business
purposes and is typically located in the home of the business (home office) or employee, the term
SOHO (Small Office, Home Office) is typically used.

, 10) At which of the OSI model layers are rules defined that determine how a device can send
data over a particular medium?
A) Presentation
B) Application
C) Transport
D) Network
E) Data link
Answer: E
Explanation: E) Of the seven OSI network model layers, the data link layer determines how a
device can send data over a particular medium, such as Ethernet data link protocols.

11) Which of the OSI model layers has the main purpose of defining and negotiating data
formatting?
ED
A) Presentation
B) Application
C) Transport
D) Network
C
E) Data link
Answer: A
O
Explanation: A) The OSI presentation layer (Layer 6) is responsible for defining and negotiating
the data format between communicating hosts. Some common formats include ASCII and
N
EBCDIC. It is also at this layer that some data conversion can occur (for example, from ASCII to
EBCDIC).

12) Which of the following terms best describes the process of adding headers and possibly
trailers to information for transit?
IS
A) Encapsulation
B) Packets
C) Frames
SE
D) Data Linking
Answer: A
Explanation: A) Encapsulation is the process of putting headers (and sometimes trailers) around
U
data for transmission. Packets and frames are defined by the data included in them. Data link is a
layer in the OSI model.
