d. Chrome OS
Answer:
a. macOS
Explanation:
Macintosh refers to a set of computers designed, developed and manufactured by Apple Inc. Apple officially began the sales of Macintosh on the 24th of January, 1984. The first designs of Macintosh are considered to be personal computers and had a mouse, in-built screen with a graphical user interface (GUI). The operating system designed and developed for Apple computers (MacBook) is known as macOS (Macintosh operating system).
A virtual assistant can be defined as a computer software program that is artificially intelligent to understand human voice commands and performs task for the end user based on instructions or commands.
Generally, macOS is an operating system that includes a virtual assistant referred to as Siri. Siri was developed and released by Apple on the 4th of October, 2011.
<em>Siri as a virtual assistant, is able to perform tasks such as setting reminders, scheduling events, media player controls, GPS navigation, internet search, answer some questions etc. </em>
Answer:
Priority programming is a process programming method based on priority. In this technique, the developer chooses the tasks to work according to priority, which is different from other types of programming, for example, a simple round-robin.
On UNIX and many other systems, higher priority values represent lower priority processes. Some of the systems, such as Windows, use the opposite convention: a higher number means a higher priority
<h3>Explanation:
</h3>
Priorities can be dynamic or static. Static priorities are assigned during creation, while dynamic priorities are assigned according to the behavior of the processes while they are in the system. To illustrate, the planner could favor intensive input / output (I / O) tasks, allowing expensive requests to be issued as soon as possible.
Priorities can be defined internally or externally. Internally defined priorities make use of a measurable amount to calculate the priority of a given process. On the contrary, external priorities are defined using criteria beyond the operating system (OS), which may include the importance of the process, the type and sum of the resources used for the use of the computer, user preferences , trade and other factors such as politics etc.
i hope this is right lol
They began in ancient times the babylons started trading
it mean for some people that have technology like a computer and there are some who don't have access to technology like phones, and tv's
This is a tough question. I’m not sure if I’ll get it right but I’ll try.
Data structures used for file directories typically have a hierarchical tree structure, referred to as a directory structure. The tree has a root directory, and every file in that system has a unique path.
The simplest method of implementing a directory is to use a linear list of file names with pointers to the data blocks. But another way that you can format a file directory is by using a hash table. With this method, the linear list stores the directory entries, but a hash data structure is also used. The hash table takes a value computed from the file name and return the pointer to the file name any linear list.
So I think it’s C. But I’m not 100% sure.
I hope that helps.
