Explain how computer system is different from computer in 150 words
Zina [86]

Answer:

To be distinguished from the physical or hardware components of a computer, programs are collectively referred to as software. A computer system, therefore, is a computer combined with peripheral equipment and software so that it can perform desired functions.

A computer is a device that does certain things (mostly very basic data manipulation and mathematical functions), just as a building is a device that does certain things (such as housing offices or apartments). What makes a computer special is that it does these things very very quickly. A computer system is a mechanism that incorporates multiple computers along with other things like data storage devices, networks, and data paths (ways to move data around among storage devices and computers), as well as software (rules for how to do things), procedures and processes and protocols and on and on. A computer system performs a rather complex function, just as a city is a system that involves multiple buildings along with roads, sewage treatment plants, water and electrical systems and many other things that enable it to perform a function considerably more complex than the function performed by a building.

A major advance in the field of computing was the advent of networking. Before that, computers had to be near each other in order to communicate with each other and computer systems typically existed in a relatively small physical location where all the computers were in the same place. If you see a movie released in the period from roughly 1950 to 1980, you will note that computers and computer systems were typically depicted as gigantic things located in a large room. With networking, a computer system might have computers in one place, remote access devices in another place, and other computers in other places. Thus a building might have computers and terminals and printers and what have you all over it, all capable of communicating with each other. The internet, which enables world wide networks, has made it possible to have computer systems that consist of thousands of computers (or more), located all over the globe.

a computer is like an engine whereas a computer system is like a vehicle (a car or truck or boat) that contains one or more engines and does something more complex than what the engine does. But the engine is the essential component that enables the vehicle to do what it does. a computer exists in a single place and does a primitive set of functions. A computer system combines a computer with many other things to perform a complex set of functions. It can also exist in a single place, but it may exist in many places at the same time.

The minimum spanning tree of an undirected graph G exists if and only if G is connected. True or False?
zlopas [31]

Answer: True

Explanation:

The definition of minimum spanning tree(MST) says that the graph must be connected and undirected to be considered for MST. It has (V-1) edges where V is the number of vertices. The minimum spanning tree is implemented using Kruskal's algorithm whereby it starts by considering the minimum weighted edge and covers all the edges upto (V-1) edges. So for MST it has to be connected

Answer:

2

  • See here we have //
  • // means floor division in python.
  • It gives us only the integer part not floating or decimal.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
sdas [7]

Answer:

The modified program in Python is as follows:

import math

paint_colors = {'red': 35,'blue': 25,'green': 23}

wall_height = int(input('Enter wall height (feet):\n'))

wall_width = int(input('Enter wall width (feet):\n'))

area = wall_height*wall_width

print('Wall area:',area,'square feet')

paint_needed = area/350.0

print('Paint needed: {:.2f} gallons'.format(paint_needed))

print('Cans needed:',round(paint_needed),'can(s)')

color = input("Choose a color to paint the wall: ")

print("Cost of purchasing", color, "paint: $",paint_colors[color])

Explanation:

The italicized are given from the question [unchanged]

<em>import math</em>

<em> paint_colors = {'red': 35,'blue': 25,'green': 23} </em>

<em>wall_height = int(input('Enter wall height (feet):\n')) </em>

This gets input for width

wall_width = int(input('Enter wall width (feet):\n'))

Calculate the wall area

area = wall_height*wall_width

Print the calculated wall area

print('Wall area:',area,'square feet')

Calculate the amount of paint needed

paint_needed = area/350.0

Print the amount of paint needed to 2 decimal places

print('Paint needed: {:.2f} gallons'.format(paint_needed))

Print the amount of can needed to nearest integer

print('Cans needed:',round(paint_needed),'can(s)')

Prompt user for color of paint [here, we assume the user input is correct]

color = input("Choose a color to paint the wall: ")

Prints the corresponding amount for the color

print("Cost of purchasing", color, "paint: $",paint_colors[color])
