All forms of data within a computer are based on digital circuits. A digital circuit can have exactly two states, one of "on" or "off". They are not able to represent intermediate values, such as "half-on" or "three-quarters off"; this would be known as an analog circuit. Since there are only two possible states for any single datum (called a "bit"), computers can only understand series of these bits ("bytes", "kilobytes", etc).
Probably for the same reason you don't.
A computer Language is the code we use to make computer understand what we want it to do. Its an Instruction set given to computer to perform some task. A computer does understands only one langue (native one) which is Binary 0 or 1 (or simply say ON or OFF) but since human are barely able to understand this language so they use interpreter that translate the code written in a language close to human being and converts it to machine code to it to understand and execute. Reverse Process is done to get the results back to humans. Such Languages are: Native: Binary (0,1) Low Level: Assembly C Intermediate: C++ High Level: C#, VB, ASP, JAVA, Python, PHP, Pearl, JASON, JavaScript, HTML, CSS, F#, Ruby ..... etc.
binary
Because the octal number sytem is more useful for writing and clearer to read. Also, we're only using the binary system since the invention of computers which is not that long ago. Before that, there was no reason to use a binary system which is again not easy to read.
The most common code originally used was a 7 bit code called ASCII (American Standard Code for Information Interchange) that was originally defined on October 6, 1960 for use with teletypes. However with only 128 values (33 of which were reserved for teletype control functions, most of which were irrelevant to computers) only standard US English characters could be represented.Since 1996 there has been a gradual transition to the variable length code called Unicode (usually in UTF-8 format) that can represent most international characters.
because it is the only language a computer understands. The computer can only tell if a switch is on or off, and that is represented by a 1 or a 0
It doesn't. The only language the computer understands is its own native machine code; binary language. We use that binary language to program the computer such that it can translate the high-level human languages that we can understand into the low-level languages that it can understand, and vice versa.
Binary.
A computer "knows" nothing but it only understands "1" or "0"(binary code)
the computer does not understands the numers and alphabets , it only recognizes 0 & 1, which is known as binary digits.
A computer doesn't actually understand any language, it just processes binary numbers.
it is the only language programmed and understandable by the computer processor because it is programmed in it.
Probably for the same reason you don't.
A computer only understand binary, which is 0 as "off" and 1 as "on."
Computer's only understand binary, which is 0 as "off" and 1 as "on."
The "1's and 0's" are referred to as binary. Binary is actually the only language a computer can understand. Everything else has to be translated to binary for it to understand it. 1 is conidered closed and 0 is open.
binary number system used in computers because computer can understand only binary language as it starts from 0and 1. which makes computer easier.
