Satellite transmission is a content distribution program, that utilizes digital signals to transmit from satellites that receive parabolic antennas widely known as satellite dishes. It's a  low noise block generator for transmitted to cooling. It also allows the user it accepts single in a wide area, and the wrong choice can be defined as follows:

  • In choice a, It allows the uses to receive a signal at all times, that's why it is wrong.

2. An evil twin attack that broadcasts a legitimate SSID for an unauthorized network is an example of what category of threat? A
avanturin [10]

Answer:

A. Spoofing

Explanation:

Spoofing is the act of disguising a communication from an unknown source as being from a known, trusted source. Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server.

IP spoofing involves an attacker trying to gain unauthorised access to a system by sending messages with a fake or "spoofed" IP address to make it look like the message came from a trusted source, such as one on the same internal computer network, for example.

Email spoofing often involves things like requests for personal data or financial transactions. The emails appear to be from trusted senders such as customers, coworkers, or managers but they are actually from cyber criminals who deliberately disguise themselves to gain your trust and your help with the action they want you to take

(4 points.) Write an algorithm (i.e., step-by-step instructions) via which someone could walk or drive from some origin to some
Elis [28]

Answer:

The algorithm is as follows :

1. Record Current Position, Final Destination

2. While Current Position is not Final Destination, repeat the following:

2.1 If destination location is up then:

  2.1.1 If an obstacle is directly above you then:

     2.1.1.1 Look for alternate position (left, right, down)

     2.1.1.2 If alternate position is found then

        2.1.1.2.1 Move there

        2.1.1.2.2 Record Current Position

     2.1.1.3 If no alternate position is found then

        2.1.1.3.1 Call for help

        2.1.1.3.2 End

  2.1.2 If no obstacle is directly above you then:

     2.1.2.1 Move up

     2.1.2.1 Record Current Position

2.2 If destination location is down then:

  2.2.1 If an obstacle is directly below you then:

     2.2.1.1 Look for alternate position (left, right, up)

     2.2.1.2 If alternate position is found then

        2.1.1.2.1 Move there

        2.2.1.2.2 Record Current Position

     2.2.1.3 If no alternate position is found then

        2.2.1.3.1 Call for help

        2.2.1.3.2 End

  2.2.2 If no obstacle is directly below you then:

     2.2.2.1 Move down

     2.1.2.1 Record Current Position

2.3 If destination location is right then:

  2.3.1 If an obstacle is directly by your right then:

     2.3.1.1 Look for alternate position (down, up, left)

     2.3.1.2 If alternate position is found then

        2.3.1.2.1 Move there

        2.3.1.2.2 Record Current Position

     2.3.1.3 If no alternate position is found then

        2.3.1.3.1 Call for help

        2.3.1.3.2 End

  2.3.2 If no obstacle is directly by your right then:

     2.3.2.1 Move right

     2.3.2.1 Record Current Position

2.4 If destination location is left then:

  2.4.1 If an obstacle is directly by your left then:

     2.4.1.1 Look for alternate position (down, up, right)

     2.4.1.2 If alternate position is found then

        2.4.1.2.1 Move there

        2.4.1.2.2 Record Current Position

     2.4.1.3 If no alternate position is found then

        2.4.1.3.1 Call for help

        2.4.1.3.2 End

  2.4.2 If no obstacle is directly by your left then:

     2.4.2.1 Move left

     2.4.2.1 Record Current Position

Explanation:

<em>The algorithm is straight forward.</em>

<em>All it does is to check for available position and move into the position if there is any available.</em>

<em>It keeps checking and moving until an obstacle prevents it from moving.</em>
