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

data

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.

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 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.

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.

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.

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.

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.

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 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.

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.

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 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.

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

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.

COMPUTER SCIENCE

Refer to the gambling game of roulette. A roulette wheel contains 18 black slots and 18 red slots that are numbered (not sequentially) 1−36. There are two green slots numbered 0 and 00. The dealer spins the wheel and spins a ball into the wheel in the opposite direction. Bets are made on which slot the ball will fall into as the wheel slows to a stop. The ball is equally likely to fall into any slot. What is the size of the sample space?
