How many unique values can 8 bits represent?
2 raised to the 8th power, or "2^8", or 256.
What is the range of numbers that can be encoded in 4 bits using 2s complement notation?
Using 4 bits the signed range of numbers is -8 to 7. When working with signed numbers one bit is the sign bit, thus with 4 bits this leaves 3 bits for the value. With 3 bits there are 8 possible values, which when using 2s complement have ranges: for non-negative numbers these are 0 to 7; for negative numbers these are -1 to -8. Thus the range for signed 4 bit numbers is -8 to 7.
How many different values can be represented by 4 binary digits?
24, or 16 (0 through 15) One binary digit (bit) can have 21 values (0 or 1). Two bits can have 22 values. Three bits can have 23 values. A five-bit number can have 25 values... and so on...
How many different values can 128 bits represent?
A 128-bit register can store 2 128th (over 3.40 × 10 38th) different values. The range of integer values that can be stored in 128 bits depends on the integer representation used.
What is the smallest decimal number that can be stored using 8 bits?
0.0000001
How many unique values can 8 bits represent?
2 raised to the 8th power, or "2^8", or 256.
If records in a database are stored using a key which is one byte long how many records can the database store?
If the key is one byte long, then there are 8 bits that can be positive or negative. With all permutations of 8 bits, that leaves 2^8 (two to the eighth power) possibilities, which is only 256 total unique values.
How many bits does a Java char contain?
16 bits. Java char values (and Java String values) use Unicode.
How many bits in octet?
Eight bits to the octet. The values are 0-255.
How many bits are in the subnet ID block and What are the values of these bits for a link-local IP address?
16 bits per block
How many bits are in the Subnet ID blocks and what are the values of these bits for a link-local IP address?
16 bits per block
How many different number can be represented using 5 bits?
Using 5 bits, a total of (2^5) different numbers can be represented. This equals 32, allowing for values ranging from 0 to 31 in unsigned binary representation. If signed representation is used (e.g., two's complement), the range would be from -16 to 15, still totaling 32 distinct values.
What is the minimum number of bits would you need to represent 9 different values?
4.1 bit for 2,2 bits for 4,3 bits for 8,4 bits for 16.
8 bits can represent how many different characters?
There are 256 possible values (or characters) in 8 bits.
What is the range of numbers that can be encoded in 4 bits using 2s complement notation?
Using 4 bits the signed range of numbers is -8 to 7. When working with signed numbers one bit is the sign bit, thus with 4 bits this leaves 3 bits for the value. With 3 bits there are 8 possible values, which when using 2s complement have ranges: for non-negative numbers these are 0 to 7; for negative numbers these are -1 to -8. Thus the range for signed 4 bit numbers is -8 to 7.
How many distinct values can we represent with 5 bits?
32 values. 2^5=32
If a binary number needs to represent 16 different values how long must the number be in bits?
4 bits
