Answer:
- def convertStr(num):
- Number = ("One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine")
- numStr = str(num)
- output = ""
-
- for x in numStr:
- index = int(x) - 1
- output += Number[index] + " "
-
- return output
-
- value = 1234
- print(convertStr(value))
Explanation:
Firstly, create a function convertStr that take one input number (Line 1).
This function convert the input number to string (Line 3) and then use for-loop to traverse through the individual digit (Line 6). In the loop, get the target index to extract the corresponding digit letter from the Number tuple(Line 7). The target index is always equal to the current digit number - 1. Next, join the extracted digit letter from the tuple to an output string (Line 8) and return it at the end of the function (Line 10).
We test the function using 1234 as argument (Line 12 - 13) and we shall get One Two Three Four
Answer:a) Mainframes, miniframes, PCs, desktop Internet computing, mobile computing
Explanation: The hierarchy of the computers or computing are in the generation is:-
- Mainframe:-designed for the execution of huge data processing , storage and execution.
- Miniframe:-has similar functioning as the mainframe but on smaller scale and version.
- Personal computer(PC):-It is designed for the individual purpose and according the need of the user.
- Mobile computing:-computing that can be done on the mobile phone similar to the computing on the personal computer
- Internet computing:-the computing of the mobile and computer system with the facility of the internet connectivity.
