How many different numbers can you represent with 16 bits?
A 16-bit integer can store 216 (or 65,536) distinct values.
In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767..
What is the largest number stored in 20 bits?
Originally Answered: What is the largest unsigned integer that may be stored in 20 BITS? If we are using unsigned, then all 20 bits contribute to magnitude. All ones is the biggest number. 20 ones.
How many values is 2 bits?
In binary (base 2), two digits can represent four different values (2 ^ 2), and in decimal (base 10), two digits can represent 100 different values (10 ^ 2). They mean exactly that: Two bits store the values 0, 1, 2, and 3, which have a binary encoding of 00, 01, 10, and 11, respectively.
What is the highest value I can count to using 3 bits?
111Explanation: Binary can be registered as either 0 or 1 and since the highest value you have is the number 111. The largest decimal number that one can represent with 3 bits is 111 because is the highest number once can represent in 3 bits.
What is the highest value in one byte?
255The maximum decimal number that can be represented with 1 byte is 255 or 11111111. An 8-bit word greatly restricts the range of numbers that can be accommodated. But this is usually overcome by using larger words. With 8 bits, the maximum number of values is 256 or 0 through 255.
How many characters is 2 bytes?
65,5362 bytes per character = 65,536 different characters! The Unicode character coding system uses 2 bytes (16 bits) per character. This means that it can represent 65,536 different characters, which is more than enough to represent every currently used language in the world!
How many numbers can be represented with 3 bits?
eightFor example, a string of three bits can represent up to eight distinct values as illustrated in Table 1. As the number of bits composing a string increases, the number of possible 0 and 1 combinations increases exponentially.
How many numbers can one byte represent?
256Hexadecimal, Octal, Bits, Bytes and Words. A single byte can represent 256 (28) numbers.
How many possible numbers can be expressed in a 2 byte space?
Given 8 bits per byte, a short integer which is allocated 2 bytes can store 216 (65,536) possible 0 and 1 combinations. If we split those between negative and positive values, the data range for a short is -32,768 to +32,767.
What is the highest value I can count to using 4 bits?
By dividing a binary number up into groups of 4 bits, each group or set of 4 digits can now have a possible value of between “0000” (0) and “1111” ( 8+4+2+1 = 15 ) giving a total of 16 different number combinations from 0 to 15.
What’s the smallest decimal number that you can represent with 3 bits?
Answer and Explanation: The smallest decimal number that you can represent with three bits is either 0 or -4.
How many digits are in 8 bytes?
5 Answers. Eight bytes contain 64 bits of information, so you can store 2^64 ~ 10^20 unique items using those bits. Those items can easily be interpreted as the integers from 0 to 2^64 – 1 . So you cannot store 302 decimal digits in 8 bytes; most numbers between 0 and 10^303 – 1 cannot be so represented.

Why do bytes have 8 bits?
The byte was originally the smallest number of bits that could hold a single character (I assume standard ASCII). We still use ASCII standard, so 8 bits per character is still relevant. This sentence, for instance, is 41 bytes. That’s easily countable and practical for our purposes.
How many numbers can 4 bytes represent?
1 Integers. Integers are commonly stored using a word of memory, which is 4 bytes or 32 bits, so integers from 0 up to 4,294,967,295 (232 – 1) can be stored. Below are the integers 1 to 5 stored as four-byte values (each row represents one integer).
What does 4 bytes mean?
4 bytes can store numbers between -2147483648 and 2147483647. 8 bytes can store numbers between -9223372036854775808 and 9223372036854775807. Adding in binary is just like normal addition with carrying. But when you run out of bits you can’t carry anymore.
How many bytes is a word?
2 bytesFundamental Data Types A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits). Figure 29-2 shows the byte order of each of the fundamental data types when referenced as operands in memory.
What happens to values above 255 in binary?
An example of an 8-bit overflow occurs in the binary sum 11111111 + 1 (denary: 255 + 1). The total is a number bigger than 8 digits, and when this happens the CPU drops the overflow digit because the computer cannot store it anywhere, and the computer thinks 255 + 1 = 0. … Many PCs have a 64-bit CPU.
What is the largest decimal value with 5 bits?
Remember, the largest unsigned value occurs when all 5 bits are 1’s (11111 = 31) 8. On most computer systems, 8 bits contitutes 1 byte.
Is 00000000 a valid byte?
When all bits have a value of 0, the byte is represented as 00000000. … Remember that the byte with all bits having a value of 0 has its value set to 0. Since this byte also holds a valid value, the number of combinations = 255 + 1 = 256.
What is the largest number that can be represented by 3 bits?
7The largest decimal number that you can represent with 3 bits is 7.
