In this video, you will see the subtraction of two numbers using the one complement method. This one has a method in which the result contains an overflow bit. If after adding there is no overflow carry. Then the result is negative and you have to complement it again.

How Integer and Floating point numbers are stored in computers
The number has two parts.
- Integer Part
- Fraction Part
Integers are numbers without the fraction part.
They can range from negative infinity to positive infinity.
Integers are further divided into two parts.- Unsigned number (0 to (2^n – 1); here n = width of data bus)
- Signed Numbers ((-2^(n-1)) to (2^n – 1))
Fractional numbers or Floating Point numbers are stored in a standard format known as IEEE 754.
IEEE 754 Floating-Point Standard comes in three different modes.- Single precision Format (32 bits)
- Double-precision format

Convert Hexadecimal number to Octal Number
Convert the number into its binary equivalence first and the make group of three digits starting from LSB and moving towards the MSB. Then you have to write the just convert the group into an octal number which will easy.

Hexadecimal Number System
In this video, I have told about the hexadecimal number system. The hexadecimal number system is widely used in electronic computer systems to represent the number systems. I have also described that we can represent fractions in the hexadecimal number system also.
-
Octal Number System
In the octal Number system, we start counting from 0 which goes up to 7. Making only 8 digits. Then after 7, we start by incrementing 1 to the tenth place and start counting from 0 up to 17.
In the video, I have described what the octal number system is and how we can convert the octal number to decimal numbers.
Just like we have fractions in decimals like 1.234, 3.9864 etc. we also have fractions in the octal number system as well like 7741.2225, 12345.654 etc.

Binary Number System
In a binary number system, there are only two possible states, HIGH state and LOW state.
These two states can be represented by current levels, voltage levels, bumps and valleys on the surface of CD/DVD etc.The two states are generally represented by a ‘0’ for LOW state and by a ‘1’ for the HIGH state.
Using the combination of 0’s(LOW) and 1’s(HIGH), we can represent the other number systems such as hexadecimal, octal or decimal into
binary number system.Bit Nibble Byte Word Dword Qword

Capacitor Time Constant=RC or Charging Time
In this video, the time constant for the capacitor is calculated.
Time Constant is denoted by the symbol tau τ
τ = R*C
Where R = value of the resistor
and C = value of capacitor
