The Software is categorized into two. Operating System Software and the Application software.
Example :
1.0 The monitor does not show pictures without the source, when watching a video the source media application 
2.0 The printer does not print on its own without the source data from the office application, print application which process the data.
3.0  The speaker does not produce sound on its own without the source data from the media application as well.
4.0  The central processing units together with the memory does not run without the preinstalled bios and operating software on the computer.

The hardware will not run without the operating software (OS) to connect run each functional part of the computer. The Central Processing Unit computes for the Inputs and Outputs fed to it giving the computer the power to process data coming from all the hardware components receiving the electrical signals translated from the data input from human interaction or other source of data interaction to the computer. To divide we mainly have your hardware components, The Central Processing Unit, The input Peripheral (mouse, keyboard, pen stylus, mics, camera, etc) and your output peripherals (Monitor, Speakers, etc.,). Then we have your software component divided into two. The operating system software (Windows /Mac OS/ Linux / Unix / ) and the application software/program (Office applications, Browser etc.,).

Write a program that prompts the user for a word or phrase, and determines if the entry is a palindrome. A palindrome is a word
vekshin1

Answer:

Explanation:

The following code is written in Python. It asks the user for an input. Then cleans the input using regex to remove all commas, whitespace, and apostrophes as well as making it all lowercase. Then it reverses the phrase and saves it to a variable called reverse. Finally, it compares the two versions of the phrase, if they are equal it prints out that it is a palindrome, otherwise it prints that it is not a palindrome. The test case output can be seen in the attached picture below.

import re

phrase = input("Enter word or phrase: ")

phrase = re.sub("[,'\s]", '', phrase).lower()

reverse = phrase[::-1]

if phrase == reverse:

   print("This word/phrase is a palindrome")

else:

   print("This word/phrase is NOT a palindrome")

16.50. Suppose we have a sequential (ordered) file of 100,000 records where each record is 240 bytes. Assume that B = 2,400 byte
Nat2105 [25]

Answer and Explanation:

Given that total number of records in a file = 100000

Each record consists of= 240 bytes

Given that B= 2400 bytes.

Then total blocks in file = 100000 records * 240 / 2400

= 10000 blocks.

Time that will take for exhaustive read

= s + r + b.btt

= 16 + 8.3 + (10000) * 0.8

= 8024.3 msec

Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.

Hence, X (s + r + btt) > 8024.3

X (16+8.3+0.8) > 8024.3

X > 8024.3/25.1

So that, X > 319.69

Hence, atleast 320 random reads should be made to search the file
