Answer:

Press Caps Lock key to see the light illuminates or not

Explanation:

Computer keyboard is the typewriter-style device that uses arrangement of the buttons or the keys to act as the mechanical levers or the electronic switches.

Keyboard keys  have characters which are engraved or printed on the surface and press of each key corresponds to the single written symbol.

If the keyboard is not working and to see whether it is working or not, there is a Caps Lock key on the keyboard. Generally, all keyboards have a Caps Lock light which will light up if the button is on. So, this can be a quick check.

Part of the central processing unit
AveGali [126]

Answer:

Explanation:

The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations.  It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division).  And logic unit (responsible for comparing, selecting, matching and merging different data or information).  The power and efficiency of the CPU depends on the design of the ALU.  

Next up is the control unit (CU) which directs all the processor’s operations.  It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary).  Then it sends the operation to various parts of the laptop as instructed.  The CU calls the ALU to perform the necessary calculations.  It also coordinates all input/output devices to transfer or receive instructions.

The main job of the memory unit is to store data or instructions and intermediate results.  It’s divided into primary memory and secondary memory to supply data to other units of the CPU.  It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.

Another element of the CPU not depicted in the diagram is transistors.  To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches.  They control the flow of electricity depending on whether the switch is ON or OFF.  Signals turn off and on different combinations of transistors to perform calculations.  A very thin silicon chip can contain several hundred million transistors.

A palindrome is a string that reads the same from left to right and from right to left. Design an algorithm to find the minimum
stepladder [879]

Answer:

Explanation:

The following code is written in Python. It is a recursive function that tests the first and last character of the word and keeps checking to see if each change would create the palindrome. Finally, printing out the minimum number needed to create the palindrome.

import sys

def numOfSwitches(word, start, end):

   if (start > end):

       return sys.maxsize

   if (start == end):

       return 0

   if (start == end - 1):

       if (word[start] == word[end]):

           return 0

       else:

           return 1

   if (word[start] == word[end]):

       return numOfSwitches(word, start + 1, end - 1)

   else:

       return (min(numOfSwitches(word, start, end - 1),

                   numOfSwitches(word, start + 1, end)) + 1)

word = input("Enter a Word: ")

start = 0

end = len(word)-1

print("Number of switches required for palindrome: " + str(numOfSwitches(word, start, end)))
