Answer:
Terrestrial microwave
Explanation:
Based on the information provided it can be said that the type of transmission system being described is called a Terrestrial microwave transmission systems. This is a system used between ground-based microwave transmission antennas which produce a narrow, highly directional signal to another antenna in order to communicate information back and forth. Although very effective, it limits the communication to only the antenna's that have a line-of-sight with each other.
Option d is correct. The correct answer is terrestrial microwave. Terrestrial microwave transmission systems are used for long-distance land-based communications, requiring clear line-of-sight between the antennas due to their high-frequency, short wavelength signals.
These systems require a clear line of sight between the transmitting and receiving antennas due to the short wavelengths of microwave signals, making them suitable for long-distance land-based communications.Microwaves, due to their high frequencies, can carry more information per unit time. This efficiency makes them ideal for both land-based long-distance communications and satellite transmissions. However, unlike cellular systems which use weaker radio transmitters for short distances, terrestrial microwave systems focus on long-distance transmission between antennas.Hence,option d is correct.
Complete Question:
___ transmission systems transmit tightly focused beams of radio signals from one ground-based microwave transmission antenna to another.
a.Satellite
b.Cellular
c.Downlink
d.Terrestrial microwave

Your network is divided into two segments. As the signal travels down the first segment, it becomes weak. To amplify the signals passing to the second segment, the network engineer installed a networking device. Which networking device did the engineer install?
Answer:
The engineer installed a Bridge
Explanation:
A bridge is a networking device that serves as a link between two or more networks, therefore, making them work as a single network. Bridges function in a similar pattern as hubs and repeaters, however, they are distinct. The MAC address table is maintained to adequately direct transmissions to the receiver.
It is worthy to note that bridges operate on the Data link layer of the OSI (Open system Interconnect) model. It connects and maintains communication between multiple networks.
The bridge installed by the engineer creates stability between the two network segments. It optimizes the signal which makes the network perform better.
If Tracy starts on the left edge of the canvas and moves forward 50 pixels, how many times will this code need to be repeated to have Tracy reach the right edge of the canvas?
answer choices
4 times
8 times
10 times
50 times
Final answer:
The number of times the code must be repeated depends on the width of the canvas, which is not provided. If hypothetically assuming a canvas width of 400 pixels, Tracy would need to move 8 times to reach the right edge.
Explanation:
The question 'If Tracy starts on the left edge of the canvas and moves forward 50 pixels, how many times will this code need to be repeated to have Tracy reach the right edge of the canvas?' is asking us to determine the number of iterations required for a movement command in a programming context to cross a given distance. To answer this, we need the width of the canvas in pixels. Once the width is known, we would divide it by the movement distance (50 pixels) to find out how many 50-pixel movements are needed to reach the right edge. Since the width of the canvas is not provided, we are unable to give a specific answer. However, if we assume the canvas is 400 pixels wide (as an example), then Tracy would need to move 400/50 = 8 times to reach the right edge.
Final answer:
To reach the right edge of the canvas, Tracy needs to repeat the code 10 times.
Explanation:
To reach the right edge of the canvas, Tracy needs to repeat the code multiple times. Let's assume that the canvas is 500 pixels wide. If Tracy moves forward 50 pixels each time, she will need to repeat the code 10 times (500/50 = 10) to reach the right edge of the canvas.
