Answer:
Cell.
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.
In the field of telecommunication, all telecommunication setup are designed and developed to make use of two network devices: one device is typically used for the transmission of data while the other device is used to receive data that are sent on the network.
Generally, cell towers are tall poles that are used to transmit frequencies to mobile phones.
Answer:
I think it is the second answer choice honestly
Explanation:
I'm gonna say either the first one or second one because the word film has something to with behind the scenes work not being an actor.
Answer:
The answer is below
Explanation:
Computer System is widely known for its ability to perform its functions faster by giving out information.
The computer system operation follows certain principles, some of which are:
1. It makes use of the OPERATING SYSTEM to link the hardware and the software together, without it, the computer system is useless.
2. It works with INPUT DEVICES such as keyboards or stylus. Without input devices, there is no way humans can communicate with the computer system
3. It works with OUTPUT DEVICES such as monitors and speakers. Without output devices, there is no way computers can communicate or give back information to humans.
4. It works with the NETWORK such as LAN or WIFI to provides the sharing of data files to other users or computers. Without the network, the computer system can only work within certain spaces, with no way to share data or files with others far away.
Answer:
The answer is "Option B".
Explanation:
The system environment includes all software external areas, which may vary from user to user. The System may be different, but it is part of the System environment, depending on the level of available memory. This environment is a part of the System development life cycle. and other options that are not correct which can be described as follows:
- In option a, Time and cost estimates are part of the SDLC. It is a part where we calculate the overall cost and time for making any new software.
- In option c, It is not a use in system environment it is reported.
- In option d, System Components are a hardware device that by system environment for making a system environment but it does not include systems security that's why it is not correct.
