Question 1

The most significant factor in choosing a transmission method is its ____.&#10;A) noise&#10;B) attenuation&#10;C) throughput&#10;D) latency

Accepted Answer

Throughput is the measure of the amount of data that can be transmitted over a given time interval. It is the most significant factor in choosing a transmission method because it determines how quickly data can be transmitted. Other factors such as noise, attenuation, and latency are also important, but they are secondary to throughput. Therefore, the best choice is C - throughput.

Question 2

One of the most common transmission flaws affecting data signals is ____.&#10;A) noise&#10;B) attenuation&#10;C) throughput&#10;D) latency

Accepted Answer

Noise is a common transmission flaw that arises due to interference from external sources. It can cause errors or loss of bits in data signals during transmission. Attenuation refers to the weakening of the signal strength as it travels over a distance, whereas throughput refers to the amount of data that can be transmitted over a period. Latency is the delay that occurs when data is transferred between two points. While all these factors can affect data transmission, noise is the most common cause of transmission flaws.

Question 3

Serial refers to a style of data transmission in which the pulses that represent bits follow one another along a ____ transmission line.&#10;A) long&#10;B) short&#10;C) secondary&#10;D) single

Accepted Answer

Serial transmission happens over a single transmission line, and the bits are sent one after the other in a continuous stream. Therefore, the answer is (D) single.

Question 4

The serial interface on the back of the connectivity device is often labeled &#34;____.&#34;&#10;A) Connector&#10;B) Port&#10;C) Board&#10;D) Console

Question 5

The distance between corresponding points on a wave's cycle is called its ____.&#10;A) amplitude&#10;B) frequency&#10;C) phase&#10;D) wavelength

Accepted Answer

The distance between corresponding points on a wave's cycle is known as wavelength. Amplitude refers to the maximum displacement of a wave from its equilibrium position, frequency is the number of cycles of a wave that occur in one second, and phase refers to the position of a wave cycle relative to a reference point.

Question 6

____ is a technology used with fiber-optic cable, which enables one fiber-optic connection to carry multiple light signals simultaneously.&#10;A) Statistical multiplexing&#10;B) WDM (wavelength division multiplexing)&#10;C) TDM (time division multiplexing)&#10;D) FDM (frequency division multiplexing)

Accepted Answer

WDM (wavelength division multiplexing) is a technology used with fiber-optic cable, which enables one fiber-optic connection to carry multiple light signals simultaneously. It works by dividing the available bandwidth on a single fiber into multiple channels, each with a different wavelength of light. This allows for higher data transmission rates and more efficient use of the available fiber-optic infrastructure.

Question 7

The byte 00001110 means ____ on a digital network.&#10;A) 3&#10;B) 6&#10;C) 14&#10;D) 30

Accepted Answer

In binary, each digit represents a power of two, with the rightmost digit representing 2^0=1, the next digit representing 2^1=2, then 2^2=4, and so on. Thus, the byte 00001110 represents 0*128 + 0*64 + 0*32 + 0*16 + 1*8 + 1*4 + 1*2 + 0*1 = 0+0+0+0+8+4+2+0=14. Therefore, the correct answer is C, which is 14.

Question 8

A digital signal composed of a pulse of positive voltage represents a(n) ____.&#10;A) 0&#10;B) 1&#10;C) 4&#10;D) 8

Accepted Answer

A pulse of positive voltage is commonly used to represent a 1 in digital electronics, while a zero is typically represented by a no pulse or a pulse of negative voltage. Therefore, the best choice is B, which represents a 1. Choices C and D are not relevant options because digital signals typically use a binary system, meaning there are only two possible values (0 or 1), and 4 or 8 are not part of that binary system. Choice A is also not the best choice because, as mentioned earlier, a pulse of positive voltage usually represents a 1.

Question 9

Which connector is used in RS-232 transmissions?&#10;A) DB-25&#10;B) ST&#10;C) BNC&#10;D) Cat-5

Accepted Answer

The DB-25 connector is typically used in RS-232 transmissions, as it has 25 pins and can accommodate the multiple signal lines required for this type of data transmission. ST, BNC, and Cat-5 connectors are used for other types of connections, such as fiber optic cables, video cables, and Ethernet cables, respectively.

Question 10

The data transmission characteristic most frequently discussed and analyzed by networking professionals is ____.&#10;A) noise&#10;B) scalability&#10;C) throughput&#10;D) cost

Accepted Answer

Throughput refers to the amount of data that can be transmitted over a network in a given amount of time, and is a key factor in determining network performance. This characteristic is often analyzed and discussed by networking professionals as it directly impacts the user experience and overall efficiency of the network. Noise, scalability, and cost are also important factors, but are not typically as heavily scrutinized as throughput when evaluating network performance.
