Numbers stored and transmitted inside a computer in binary or ascii?
Binary.
Why do digital computer use binary number system?
Binary numbers have only 2 digits, 0 and 1. Binary came from a need to represent information based in magnetics that only offer an "on" or "off" state. Decimal numbers have 10 digits, 0,1,2,3,4,5,6,7,8,9. Decimal numbers came about from humans having 10 fingers to count with. Once they reach 10, they start reusing fingers (digits). When humans count to 3, they count to their 3rd digit. Here's how to count to 3 in binary, which only has 2 digits: 01,10,11 Here's counting to 7 in decimal: 1,2,3,4,5,6,7 Here's counting to 7 in binary: 001,010,011,100,101,110,111 All of the mathematics done in decimal can be done in binary. No matter how fancy computers get, the bottom line is they have to store and manipulate information at a physical level, something physical must store all of that information. In computers, that physical storage is magnetic. All information is stored and manipulated at the lowest level as a combination of large binary values, large combinations of "on" and "off". Scientists are inventing new ways to store information in computers, so perhaps in time computer storage won't be limited to binary values.
Where do you use sign binary number?
Whenever a computer program uses integers - for example, in a game, to store a player's score, but also for many other situations - this will internally be stored as a binary number. This number may be signed or unsigned. Some programming languages, such as Java, only use signed numbers. In other cases, the programmer may decide to use either signed or unsigned numbers, depending on his needs.
How is scientific notation related to the floating point representation used by computers?
Floating point numbers are stored in scientific notation using base 2 not base 10.There are a limited number of bits so they are stored to a certain number of significant binary figures.There are various number of bytes (bits) used to store the numbers - the bits being split between the mantissa (the number) and the exponent (the power of 10 (being in the base of the storage - in binary, 10 equals 2 in decimal) by which the mantissa is multiplied to get the binary/decimal point back to where it should be), examples:Single precision (IEEE) uses 4 bytes: 8 bits for the exponent (encoding ±), 1 bit for the sign of the number and 23 bits for the number itself;Double precision (IEEE) uses 8 bytes: 11 bits for the exponent, 1 bit for the sign, 52 bits for the number;The Commodore PET used 5 bytes: 8 bits for the exponent, 1 bit for the sign and 31 bits for the number;The Sinclair QL used 6 bytes: 12 bits for the exponent (stored in 2 bytes, 16 bits, 4 bits of which were unused), 1 bit for the sign and 31 bits for the number.The numbers are stored normalised:In decimal numbers the digit before the decimal point is non-zero, ie one of {1, 2, ..., 9}.In binary numbers, the only non-zero digit is 1, so *every* floating point number in binary (except 0) has a 1 before the binary point; thus the initial 1 (before the binary point) is not stored (it is implicit).The exponent is stored by adding an offset of 2^(bits of exponent - 1), eg with 8 bit exponents it is stored by adding 2^7 = 1000 0000Zero is stored by having an exponent of zero (and mantissa of zero).Example 10 (decimal):10 (decimal) = 1010 in binary → 1.010 × 10^11 (all digits binary) which is stored in single precision as:sign = 0exponent = 1000 0000 + 0000 0011 = 1000 00011mantissa = 010 0000 0000 0000 0000 0000 (the 1 before the binary point is explicit).Example -0.75 (decimal):-0.75 decimal = -0.11 in binary (0.75 = ½ + ¼) → 1.1 × 10^-1 (all digits binary) → single precision:sign = 1exponent = 1000 0000 + (-0000 0001) = 0111 1111mantissa = 100 0000 0000 0000 0000 0000Note 0.1 in decimal is a recurring binary fraction 0.1 (decimal) = 0.0001100110011... in binary which is one reason floating point numbers have rounding issues when dealing with decimal fractions.
What is the Largest real number that can be stored in binary using 16 bits?
1111 1111 1111 1111 = 2^16 = 65536
Why is information stored in some kind of binary format in computers?
Information is stored in some kind of binary format in computers because computer memory is made out of binary digits (bits).
Numbers stored and transmitted inside a computer in binary or ascii?
Binary.
In what form is data stored in a computer system?
It is stored in binary, that is in the form of ones and zeroes.
Numbers are stored and transmitted inside a computer in?

How binary patterns are stored and transmitted in a computer system?
i do not know how binary is transmitted but i know it is saved as 8 digits representing a number or letter bitmap images will use binary to show were to place colours if you use these 3 patterns 1101100, 11100010 and 1110110 you will get a pattern. A Capital A in binary is represented by 01000001. every 8 digits is a byte. all binary patterns are use ASCII ASCII (American Standard for Information Interchange) as this is the standard saving type.
What is stored on a computers harddrive?
Everything. All of the code that tells the computer how to boot up and shut down and all of your files and programs.
Why all data stored in a computer in binary form?
Because binary (0 or 1) is the only format that the computer can understand. A transistor is either off or on. There is no other state.
Why are MAC addresses written as six pair of Hexadecimal numbers?
Any data is stored internally in the computer as binary digits, but those are "bulky" - you need 4 binary digits for every hexadecimal digit, so hexadecimal is really a kind of shortcut to write out binary numbers.Decimal is another option, but conversion between binary and decimal is more cumbersome than with hexadecimal. Therefore, for the new IP addresses (IP version 6), they decided to write them down in hexadecimal, instead of the decimal that is used for IPv4.
What is a binary float?
It is the way computers store irrational numbers. e.g. in a 4-byte binary float, which contains 32 digits of 0 and 1. the first digit says whether the number stored is positive or negative. The next 8 digits store the value of the power of 10 when the number is in scientific notation, and the remaining 23 digits store the actual digits of the number.
Where does the word digital come from?
Digital information is stored using a series of ones and zeros or binary "digits". See the related link for more information.
What are the advantages and disadvantages of binary code decimal?
Advantage of binary over decimal: information can be recorded and stored in any dichotomous variable: magnetised or not magnetised (most electronic media), pit or no pit (optoelectronic media CDs/DVDs). For decimal it would be necessary to store as 10 different levels of magnetisation or depths of pits. Not so easy to make such a system error-free. Advantage of decimal over binary: fewer "digits" required. Every ten binary digits (1024 values) can be replaced by just a shade more than three decimal digits (1000 values). So the number of digits to be stored is less than a third.
What do bytes take the form of?
A byte (in computer terminology) is equal to 8 bits. A bit is a single binary number (0 or 1). Therefore a byte takes the form of 8 of the smallest pieces of data stored by a computer.
