Binary Number System is one the type of most popular Number Representation techniques that used in digital systems. In the Binary System, there are only two symbols or possible digit values, i.e., 0 (off) and 1 (on). Represented by any device that only 2 operating states or possible conditions. Generally, there are two types of complement of Binary number: 1's complement and 2’s complement. To get 1’s complement of a binary number, simply invert the given number. For example, 1’s complement of binary number 110010 is 001101. To get 2’s complement of binary number is 1’s complement of given number ... Read More

Negative numbers can be distinguishable with the help of extra bit or flag called sign bit or sign flag in Binary number representation system for signed numbers. It is not possible to add minus or plus symbol in front of a binary number because a binary number can have only two symbol either 0 or 1 for each position or bit. That’s why we use this extra bit called sign bit or sign flag. The value of sign bit is 1 for negative binary numbers and 0 for positive numbers.When an integer binary number is positive, the sign is represented ... Read More

Variables such as integers can be represent in two ways, i.e., signed and unsigned. Signed numbers use sign flag or can be distinguish between negative values and positive values. Whereas unsigned numbers stored only positive numbers but not negative numbers.Number representation techniques like: Binary, Octal, Decimal, and Hexadecimal number representation techniques can represent numbers in both signed and unsigned ways. Binary Number System is one the type of Number Representation techniques. It is most popular and used in digital systems. Binary system is used for representing binary quantities which can be represented by any device that has only two operating ... Read More

A number system is a set of symbols used to represent values derived from a common base or radix. In a number, the value of each digit can be determined using digit, position of the digit in the number, and the base of the number system. The base is defined as the total number of digits are available in the number system. This is known as positional number system.Number SystemBaseDigit UsedBinary20, 1Octal80, 1, 2, 3, 4, 5, 6, 7Decimal100, 1, 2, 3, 4, 5, 6, 7, 8, 9Hexadecimal160, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, ...

Zero (0) is used as a number and also as the numerical digit. Zero gives the additive identity of the integers, real numbers, and many algebraic structures. It is used as a placeholder for writing numbers.Natural numbers start from 1, then 2 and so on. We cannot count backward with them. Integers, on the other hand, allows us to count backward. Zero winds up being a good choice for the number that should come after 1 as we count backward. Integers can go in both directions, to a positive infinity and also in the reverse direction to a negative infinity. ... Read More

Proper Earthing is a must for safe usage of electricity. Earthing ensures a proper discharge path for the flow of electricity and hence is recommended for any plug pin connected to the circuit board.It's One-OhmIt is always safe to connect the Earthing wire dug into the ground. All the grounding paths should be accessible. This path resistance from the farthest barrier to this grounding electrode should not exceed one ohm. One-ohm resistance or below One-ohm is the suggested value of resistance for an earthing path to be safe and secure.

British standard system is the system which is based on ISO systems. In this standard system, there is a total of twenty grades of tolerance. The eight grades cover sizes up to 550 mm and the twelve cover set grades up to 3120 mm. The tolerances in these systems for which each grade varies over the range of sizes which have to be produced as soon as possible and the same standard for relative accuracy in each size.Take an example when the tolerance in grades which ranges from 0.014 mm of sizes below 5 mm to 0.350 mm for sizes ...

Mach number is the ratio of the velocity of the object with respect to the velocity of sound. Mach number is represented by "M". The formula for M is v/c, where v is the velocity of the object and c is the speed of sound which is approximately 330 m/s. The speed of sound varies due to a number of factors like temperature, altitude etc. thus depending on the surrounding conditions we estimate the value of "c".Mach 1 implies that the body is travelling at a speed equal to the speed of sound. If Mach number < 1 it implies ... Read More
