Answer: Time Division Multiple Access (TDMA)
Explanation:
Time Division Multiple Access (TDMA) is a digital cellular telephone communication technology which allow many users to share the same frequency without interference. It works by dividing a signal into different timeslots, and increasing the data carrying capacity.
Time Division Multiple Access (TDMA) is a complex technology since it requires accurate synchronization between the transmitter and the receiver. Again, TDMA is used in digital mobile radio systems. The individual mobile stations cyclically assign a frequency for the exclusive use of a time interval.
In most instances, the entire system bandwidth for an interval of time is not assigned to a station. But the frequency of the system is divided into sub-bands, and TDMA is used for the multiple access in each sub-band. Sub-bands are referred to as carrier frequencies and the mobile system that uses Sub-bands are known as the multi-carrier systems.
Consider this illustration, the frequency band has been shared by three users. Each user is assigned definite timeslots to send and receive data. user ‘2' sends after user ‘1’ and user ‘3’ sends thereafter. More users can be added too.
From the question, Time Division Multiple Access (TDMA) are developed to improve the efficiency and quality of digital communications and it can divide a channel into six or more time slots.
Answer: Twisted pair cable
Explanation:
Twisted pair cabling simply refers to a wiring whereby two conductors that are gotten from a single circuit will be twisted together so that their electromagnetic compatibility can be enhanced.
This type of network cable is commonly used to connect office computers to the local network and it is used for Ethernet networks. A circuit is formed from the pair of wires which can be used in the transmission of data.
I will be able to help you on this question, were there options given?
Probably not
Not a good idea my friend
Yes, of course.
When you replace people with technologically advanced robots, it can disturb the economic factors. Although I don't agree with using robots as an every day, common thing, such as self-driving cars or like in the question, using robots as doctors. Technology is technology, it will always need updates and sometimes they break down or need repairs, so that could provide jobs for people; tech jobs that is. Not everybody is tech savvy though, but you learn. I still don't agree with it, but it is what it is.
