Answer:
a. labels
Explanation:
a. labels b. graphs c. numbers d. formulas
It is the labels, which is the title of each column. For one column we can have the names, for another column, we can have a label grade. and for the third column, we can have the label scores. And the others are the graphs, formulas and the numbers, which are not an option.
Since Joan wants to see what her presentation would look like in the eyes of her audience, it might be best for her to use the Slideshow view that is available at the bottom right side of her desktop view.
This option is a full-screen form of her Normal view in Microsoft PowerPoint. The Slideshow view is represented by the projector screen symbol next to the zoom in and out bar.
Answer:
D) can access main memory at the same time as the main CPU
Explanation:
DMA is short for Direct Memory Access, these controllers allow the device to transfer data directly to and from the memory modules without interfering with CPU processes. Therefore it can access main memory at the same time as the main CPU. Thus freeing up CPU processing power for other tasks while also retrieving the data necessary.
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.
