Best Answer

The (transistor) switches in an electronic computer, have only two states, ON and OFF.

Binary has only two numbers 1 and 0.

Large numbers can be represented by digits (bytes), made up entirely of ones and zeros.

Many early computers used Decimal Numbers (ENIAC, UNIVAC I, IBM 650, IBM 702, IBM 705, IBM 7070, IBM 7080, IBM 1401, IBM 1620, etc.). However the circuitry to do this is more complex than the circuitry to use Binary Numbers. Also software can easily be written to convert between decimal & binary forms, removing the need for complex decimal circuitry that early designers often felt was required.


Russian designers built some computers that used Trinary Numbers. However circuits that reliably identify 3 states in one signal are harder to design than circuits that reliably identify 2 states in one signal.

What is the binary number for the decimal number 134?

The binary number for the decimal 134 is calculated as 128+4+2=10000110. The binary number system is used internally on almost all computers and computer based devices like cell phones.


How the computer can understand binary language?

The computer understands binary because the 1 means on and the 0 means off, so that controls how it operates. Binary language is then converted to our number system where the numbers represent things. ASCII code is used to convert binary to text.

Why binary numbers are used in engineering activities?

The binary number system (base 2) is the basis for computer math and operations. Computer circuitry can represent two states (On/Off, Positive Voltage/Negative Voltage, Magnetized North/Magnetized South, etc). Any engineering which deals with the internal workings of a computer, or transmitting data to/from a computer would need to represent the data in binary (base 2) number system.


Use of binary number in business?

Binary number are hardly ever used in business.


Why did computer don't used binary?

Actually, computers do use binary. Other languages are simply used for easier readability (because binary is difficult for most humans to understand). These "high level" languages are then placed into an interpreter and then compiled into a program that uses binary to communicate with the computer.
