What are the six peripherals of a computer system
Lubov Fominskaja [6]
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.

What does it mean to design,<br> implement, and maintain computer<br> systems?
docker41 [41]

Answer:

Let's take an example of the embedded system, which is a perfect example of this question as a computer system. Suppose we want the embedded system to record the details related to soil of agricultural land. We will take an IoT device which will be a sensor that can register soil properties, and get connected to the computer system through the internet. And we design an embedded system that registers these values and then copy them like somewhere in DB space on Amazon cloud or Google cloud. And finally display on some LCD or a big projector, or whatever, and like we design. Thus we have designed, and now when we install this on agriculture land, we implement it, and since check regular for correct performance, we maintain this embedded or a mini-computer system as well. This is what design, implement and maintain computer systems mean.

A. increase the pace of research in finding and producing vaccines.

Explanation:

These are the options for the question;

A. increase the pace of research in finding and producing vaccines.

B. analyze computer systems to gather potential legal evidence.

C. market new types of products to a wider audience.

D. create more intricate screenplays and movie scripts.

Modeling software can be regarded as computer program developed in order to build simulations as well as other models. modelling software is device by international researchers to make research about different vaccines and other drugs and stimulants to combat different diseases. It helps the researcher to devoid of details that are not necessary and to deal with any complexity so that solution can be developed. It should be noted that Sophisticated modeling software is helping international researchers to increase the pace of research in finding and producing vaccines.
