Answer:Answer:
TRUE
Explanation:
SATCOM in the Ku- and Ka- bands, as well as EHF systems are adversely affected by rain (the higher the frequency, the greater the effect) because one of the factors that affects availability in a satellites is rain. Higher frequencies in Ka-band (30/20 GHz), rain can have a very large effect that simply cannot be overcome at the usual levels of availability.
Rain reduces the quality of signals by interfering with the signals thereby, reducing their strength and quality.
Therefore Rain can not only degrade a satellite's signal, it can also cause a complete outage of the satellite's.
Answer:
Suzanne needs a blog
Explanation:

Answer:
d) Online, real-time systems.
Explanation:
The options are:
a) Batch processing systems.
b) Personal computer systems.
c) Data compression systems.
d) Online, real-time systems.
And the correct option is D. Online, a real-time system. And this is because it is this which is characterized by the data which is assembled from more than one location as it is online, and various clients from various locations enter the data, and it's updated immediately, as it is a real-time system, which is updated in real-time. And hence D. is the correct option. The data compression system takes the data from one location at a time. The batch processing system is made up of different programs for input, output, and process. and hence is different from real-time, which requires continual all the three. And a PC is not made to a specific function, and it does different activities. Hence, its also not the right option here.
Answer:
b. This would set the group ownership of file1 to root.
Explanation:
Linux allows user to have his own files and regulate the ability of other users to access them. The <em>chown</em> command allows you to use the appropriate utility to change the owner of a file or directory.
The basic command syntax is as follows:
# chown [options] <owner name: owner group name> <file or directory name>
For example, if you want to give a user <em>root</em> opportunity to use the <em>file1.txt</em> file as he wishes, you can use the following command:
# chown root file1.txt
In addition to changing the owner of a file, the group of its owners or both can be changed at the same time. Use a colon to separate the username and user group name (without the space character):
# chown user2:group2 file1.txt
As a result, the user with the name <em>user2</em> will become the owner of the <em>file1.txt</em> and its group will become <em>group2</em>.
In your case omitting username
# chown :root file1.txt
will change owner group only.
Relational operators allow an end user to <u>compare</u> numbers.
<h3>What are
relational operators?</h3>
Relational operators can be defined as a programming language construct which allows an end user to compare both numbers and char values.
Also, it can be used to determine whether one number is less than (<), greater than (>), equal to (=), or not equal to another.
This ultimately implies that, relational operators allow an end user to <u>compare</u> numbers.
