Chapter 1 Quiz

Which two devices are considered end devices? (choose two.)

laptop, printer Refer to curriculum topic: 1.2.2 A device that forms the interface between users and the underlying communication network is known as an end device. End devices are either the source or destination of a message.

What is the delay in the amount of time for data to travel between two points on a network?

latency Latency is a term used to indicate delay when getting a packet from one point to another. Network connections with small amounts of delay are called low-latency networks, whereas network connections with long delays are called high-latency networks. High latency creates bottlenecks in any network communications.

In fiber-optic media, the signals are represented as patterns of

light In fiber-optic media, the physical layer produces the representation and groupings of bits as patterns of light.

which term is used to describe a network device with the primary function of providing information to other devices

server Refer to curriculum topic: 1.2.1 Servers are devices with software installed that allows them to provide information, like web pages or email.

Which items are collectively referred to as network media?

wires and radio waves Refer to curriculum topic: 1.2.2 Network media is a term used to describe the actual physical layer transport along the path over which an electrical signal travels as it moves from one component to another.

When a user is visiting an e-learning website to learn about networking, the user computer is acting as a?

- client, host, client device, host device Refer to curriculum topic: 1.2.1 In this scenario, the computer is reliant on the e-learning website to provide the necessary information required for the user to learn about networking. Therefore, the computer is the client device.

What is the purpose of an IP address?

It identifies the source and destination of data packets on a network. Packets that are routed across the Internet contain source and destination IP addresses. These addresses are used to determine how the packets should be routed from source to destination by intermediate devices. 1.3.2

Which statement describes the ping and tracert commands?

Tracert shows each hop, while ping shows a destination reply only. Refer to curriculum topic: 4.2.3 The ping utility tests end-to-end connectivity between the two hosts. However, if the message does not reach the destination, there is no way to determine where the problem is located. On the other hand, the traceroute utility (tracert in Windows) traces the route a message takes from its source to the destination. Traceroute displays each hop along the way and the time it takes for the message to get to that network and back.

What is the internet?

a network of networks Refer to curriculum topic: 1.1.1 The Internet is essentially a network of networks. Each user connects to the Internet by using a physical cable or through wireless media. Underneath this network of networks lies a very real backbone of connections that bring the world to personal computing devices.

bit

a one or a zero

gigabyte

approximately one billion bytes

megabyte

approximately one million bytes

kilobyte

approximately one thousand bytes

terabyte

approximately one trillion bytes

What terms represent the maximum and actual speed that can be utilized by a device to transfer data?

bandwidth; throughput Refer to curriculum topic: 1.1.3 Bandwidth measures the maximum rate at which a device can transfer data. However, in practice, the actual speed for data transfer could be reduced because of numerous factors like network congestion, overhead etc. This actual rate of transfer is known as throughput.

Information in its raw or unorganized form that represents something is known as:

data

What is an advantage of the peer-to-peer network model?

ease of setup Refer to curriculum topic: 1.3.1 The simplest peer-to-peer network consists of two computers that are directly connected to each other through the use of a wired or wireless connection. The advantages of peer-to-peer networking include ease of setup, lower cost, and less complexity.

byte

eight bits

Refer to the exhibit. Which term correctly identifies the device type that is included in the area B?

intermediary Refer to curriculum topic: 1.2.2 Routers and switches are intermediary devices. End devices consist of PCs, laptops, and servers. They also include printers, VoIP phones, security cameras, and hand-held devices.

What type of network is defined by two computers that can both send and receive requests for resources?

peer-to-peer Refer to curriculum topic: 1.3.1 The simplest form of peer-to-peer networking consists of two computers that are directly connected to each other through the use of a wired or wireless connection.

Which criterion can be used to select the appropriate type of network media for a network?

the environment where the selected medium is to be installed Refer to curriculum topic: 1.2.2 Criteria for choosing a network medium are the distance across which the selected medium can successfully carry a signal, the environment in which the selected medium is to be installed, the amount of data and the speed at which the data must be transmitted, and the cost of the medium and its installation.
