The three main components of an operating system are:

1. manage the computer's resources (this includes the central processing unit, memory, printers, and disk drives).

2. establish a user interface (this is where the human interacts with a computer, website or application. the UI, also known as user interface, is to make the user's experience easy and intuitive).

3. execute and provide services for applications software (this is the interface between the application program and the hardware, which gets carried out from OS).

Your task is to build a palindrome from an input string.A palindrome is a word that readsthe same backward or forward. Your code
White raven [17]

Answer:

The program in Python is as follows:

word = input("Word: ")

if len(word) < 5:

   print("At least 5 characters")

else:

   pal = word[0:5]

   word = word[0:4]

   word = word[::-1]

   pal+=word

   print(pal)

Explanation:

This gets the word from the user

word = input("Word: ")

This checks if the length of the word is less than 5.

if len(word) < 5:

If yes, this tells the user that at least 5 characters is needed

   print("At least 5 characters")

If otherwise

else:

This extracts the first 5 characters of the word into variable named pal

   pal = word[0:5]

This extracts the first 5 characters of the word into variable named word

   word = word[0:4]

This reverses variable word

   word = word[::-1]

This concatenates pal and word

   pal+=word

This prints the generated palindrome

   print(pal)

topjm [15]

Answer:

1946

First, to deal with the more recent and most familiar meaning of the word ‘computer’: the word first came to mean an electronic device used to store and communicate information (and all of its subsequent functions) only in the 1940s: the earliest citation in the Oxford English Dictionary is from 1946. This is fitting.
