Software that people commonly use in the workplace to make their lives easier is called system software.
A system of interconnected computers that share a central storage system and various peripheral devices such as a printers, scanners, or routers. Each computer connected to the system can operate independently, but has the ability to communicate with other external devices and computers

Answer:
```
file = open("trips.txt","r")
file = file.split("\n")
trip_date = []
fuel_used = []
miles_traveled = []
for i in file:
trip_date.append(i.split(", ")[0])
for i in file:
fuel_used.append(i.split(", ")[1])
for i in file:
miles_traveled.append(i.split(", ")[2])
```
This should put the data in their own lists (i didn't test it) but im not going to solve everything for you. The rest is for you to tinker with. You shouldn't throw your question at us and expect an answer. This is the most that I will give you.
Explanation:
Answer: ARPANET
Explanation: The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.
Answer:
D
Explanation:
A. Polarization is simple for most antennas to determine. It is only on the same level as the antenna components. A vertically polarised antenna (that is one with vertical elements) is better received and a horizontal antenna is equally provided with horizontally polarised signals.
B. The left-hand circular polarization is named if the electric chambers vector rotates counter-clockwise as far as they are from the antenna.
The right-hand circular polarisation is named as the electric field vector rotates counter-clockwise as far as it gets from the antenna.
It then goes without stating the polarisation on the right hand is orthogonal to the left.
C. signals of the same frequency can be transmitted together in an non-interfering manner as long as their polarizations are orthogonal to one another. This too a correct statement.
