Answer:
System preferences.
Explanation:
MacOS is the primary operating system designed and developed for Apple computers (MacBook).
In macOS, system preferences is a launch point that provides access to almost all the settings needed to administer a macOS system. The system preferences allow users to change various settings on their Mac computers such as changing the desktop layout, desktop picture (wallpaper), size and location of the dock, font size, appearance, energy saver etc.
Answer:
1. Processor communication -- this involves the following tasks:
<em>a. exchange of data between processor and I/O module</em>
<em>b. command decoding - I/O module accepts commands sent from the processor. E.g., the I/O module for a disk drive may accept the following commands from the processor: READ SECTOR, WRITE SECTOR, SEEK track, etc. </em>
<em>c. status reporting – The device must be able to report its status to the processor, e.g., disk drive busy, ready etc. Status reporting may also involve reporting various errors. </em>
<em>d. Address recognition – Each I/O device has a unique address and the I/O module must recognize this address. </em>
<em />
2. Device communication – The I/O module must be able to perform device communication such as status reporting.
3. Control & timing – The I/O module must be able to co-ordinate the flow of data between the internal resources (such as processor, memory) and external devices.
4. Data buffering – This is necessary as there is a speed mismatch between speed of data transfer between processor and memory and external devices. Data coming from the main memory are sent to an I/O module in a rapid burst. The data is buffered in the I/O module and then sent to the peripheral device at its rate.
5. Error detection – The I/O module must also be able to detect errors and report them to the processor. These errors may be mechanical errors (such as paper jam in a printer), or changes in the bit pattern of transmitted data. A common way of detecting such errors is by using parity bits.
Answer:
A. a collection of organized data.
Explanation:
It can be a data source, or a database, an excel sheet. or access database. However, it must be well-formatted and hence organized. filtering of data is not necessary, as well as it is not any barrier to the number of the set of data, or the data being sorted. Unsorted data is also fine, and multiple set of data is also fine. It must be known that a data source can be formed from multiple sets of data through the query. And the resultant data source can be used by the mail merge. However, the data source must be a collection of organized data. Hence, A is the correct answer.
Answer:
Wait. Then you try it again
Explanation:
You wait and try again later and if this still persists, you may have to check the optical drive from the drive manager peradventure there is an issue there probably a software issue, also you may have to clean the optical drive using the cleaner disc, likewise you may need to test an old disc on the optical drive to be sure the fault is not from the disc you inserted.
