Give 5 uses of software and hardware.

1 answer:

7 0

Computer hardware is any physical device used in or with your machine, whereas software is a collection of code installed onto your computer's hard drive. For example, the computer monitor you are using to read this text and the mouse you are using to navigate this web page is computer hardware. The Internet browser that allowed you to visit this page and the operating system that the browser is running on is considered software.

All software utilizes at least one hardware device to operate. For example, a video game, which is software, uses the computer processor (CPU), memory (RAM), hard drive, and video card to run. Word processing software uses the computer processor, memory, and hard drive to create and save documents.

In a computer, hardware is what makes a computer work. A CPU processes information and that information can be stored in RAM or on a hard drive. A sound card can provide sound to speakers and a video card can provide an image to a monitor. All of this is hardware.

Consider the clipping of a line segment in two dimensions against a rectangular clipping window. Show that you require only the

Semmy [17]

Answer / Explanation:

Assuming we define the end points as ( x₁ , y₁) and (x₂ , y₂) and the rectangular window edge as ( Xmin ,Ymin and Xmax , Ymax)

The illustration of the above assumption is represented in the diagram below.

Now, suppose the line segment is between the points P₁ = ( x₁ , y₁) , and

P₂ = (x₂ , y₂).

We can then create a line recalling and using parametric form,

P(t) = ( 1 - t) P₁ + tP₂ , t ∈ {0 , 1 },

So, for the X axis, we have,

tₓ = P₁ₓ - x ÷ P₁ₓ - P₂ₓ

We need to note that at this point we need to know the minimum and maximum unclipped values for parameter t from each dimension.

Therefore,

- ( tmin , tmax ) = ( 0,1) means unclipped line

-tmin > tmax means completely clipped out line

– Some other range means partially clipped out line.
