Explain with examples the roles of system software and application software?​

Computers and Technology

Answer:

System software and application programs are the two main types of computer software. Unlike system software, application software -- often just called an application or app -- performs a particular function for the end user. Some examples of application software include the following:

web browsers

email clients

word processors

spreadsheets

Explanation:

Application software and system software are coded differently. System software is written in system programming languages -- such as Executive Systems Problem Oriented Language (ESPOL) -- designed to provide easy access to the underlying computer hardware. Application programs are written in general-purpose languages, such as Pascal, that enable the program to use the same code on different platforms. Some languages, such as C, are used for both system and application software.

System software and application software are also triggered differently. System software is generally triggered when a computer or device is turned on, and it remains on until the device is powered down. Application software is triggered by an end user after the computer is turned on. Application software needs system software to function, whereas system software can run independently of application software.

In most cases, end users do not interact with system software because it runs in the background. By contrast, end users do interact with application software -- installing it, booting it up, using it to perform certain tasks, booting it down and uninstalling it.

Fantom [35]

Complete question:

Scrabble is a word game in which words are constructed from letter tiles, each letter tile containing a point value. The value of a word is the sum of each tile's points added to any points provided by the word's placement on the game board. Write a program using the given dictionary of letters and point values that takes a word as input and outputs the base total value of the word (before being put onto a board). Ex:  If the input is:  PYTHON

the output is: 14

part of the code:

tile_dict = { 'A': 1, 'B': 3, 'C': 3, 'D': 2, 'E': 1, 'F': 4, 'G': 2, 'H': 4, 'I': 1, 'J': 8,  'K': 5, 'L': 1, 'M': 3, 'N': 1, 'O': 1, 'P': 3, 'Q': 10, 'R': 1, 'S': 1, 'T': 1,  'U': 1, 'V': 4, 'W': 4, 'X': 8, 'Y': 4, 'Z': 10 }

Answer:

Complete the program as thus:

word = input("Word: ").upper()

points = 0

for i in range(len(word)):

   for key, value in tile_dict.items():

       if key == word[i]:

           points+=value

           break

print("Points: "+str(points))

Explanation:

This gets input from the user in capital letters

word = input("Word: ").upper()

This initializes the number of points to 0

points = 0

This iterates through the letters of the input word

for i in range(len(word)):

For every letter, this iterates through the dictionary

   for key, value in tile_dict.items():

This locates each letters

       if key == word[i]:

This adds the point

           points+=value

The inner loop is exited

           break

This prints the total points

print("Points: "+str(points))

makvit [3.9K]

Answer:

Please find the detailed answer as follows:

Explanation:

Long-term average cell rate is also called as sustained cell rate(SCR). It can be defined as the maximum average cell rate in a log time period(T).

The relation among the SCR, Average cell rate and Peak cell rate is as follows:

Avg.cell rate ≤ SCR ≤ PCR

If the source producing fixed-length cells at constant rate, then the long-term average cell rate will be same as peak cell rate(PCR).
