Peripherals fall into three categories:
1. input devices are devices that put commands inside computers such as keyboards, mouses, and joysticks but the first two are the mostly used nowadays
2. output devices are what computers give out such as monitors, printers, speakers and I think projectors also fall into that category
3.storage devices such as a optical drive, hard drive, SDD, flash drive
So the main ones might be a mouse, keyboard, monitors, I think printers, hard drives and flash drives but speakers might be considered as one instead of a flash drive.
Here are the main functions of an operating system:
1) Manage the resources of the device
The operating system controls how much of each resource is distributed, and it controls things like the processing unit and memory.
2) Establish a interface for the user of the device
The operating system must classify what the classes of the script/code have to do and what they implement.
3) Service application software
The operating system must service each application that is downloaded onto the device. It must balance it's use of storage between apps.
Answer: Depends on the power of the computer /computers and the UPS
Explanation: For someone who had a big connected network of computers and printers we would plug the computer or server into the UPS as well as the monitor and sometimes a printer sometimes the monitor was plugged into the wall
When you get a UPS you must plug it in for a certain time could be hours or even a day. A USP has a big battery in it and you must charge it (sometimes it comes semi-charged but you must plug it in to strengthen it. )
there are two connector wires that you affix to the battery and you must put a lot of strength into it to make it secure.
So in closing, you can get away with two like a desktop and a laptop.

Answer:
Option b It executes a new process, which runs at the same time as the parent
Explanation:
The exec is one of the Java Runtime methods which is used to create a new process and run it as an separate process. Exec method executes the string command that we place inside the bracket. For example,
Process proc = Runtime.getRuntime().exec("Notepad.exe");
The statement above offers a convenient way to open the another computer software such as Notepad when running the program.
