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.
How many bits are needed in order to represent the decimal values from 0 to 15?
4 bits. 24 = 16, so you have 16 different combinations.4 bits. 24 = 16, so you have 16 different combinations.4 bits. 24 = 16, so you have 16 different combinations.4 bits. 24 = 16, so you have 16 different combinations.
How many bits do you need to represent 63 values using 8 bits per value?
To represent 63 values, you need at least 6 bits, as 2^6 = 64, which can accommodate all 63 values. However, if you're specifically using 8 bits per value, then you would use 8 bits for each of those 63 values, resulting in a total of 63 x 8 = 504 bits.
How many unique values can 8 bits represent?
2 raised to the 8th power, or "2^8", or 256.
How many bits required to store a?
To determine how many bits are required to store a specific value, you need to know the range of values that must be represented. The formula to calculate the number of bits (n) needed is ( n = \lceil \log_2(V) \rceil ), where ( V ) is the number of unique values. For example, to store integers from 0 to 255 (256 values), you would need 8 bits, since ( \log_2(256) = 8 ).
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.
What is the total range of decimal values that can be represented in eight bits?
In an 8-bit binary system, the total range of decimal values that can be represented depends on whether the representation is signed or unsigned. For unsigned 8 bits, the range is from 0 to 255. For signed 8 bits, using two's complement, the range is from -128 to 127.
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 different values can be stored in 4 bytes?
Four bytes can store (2^{32}) different values, since each byte consists of 8 bits and 4 bytes equal 32 bits. This means that the total number of unique combinations is (2^{32} = 4,294,967,296). This range includes values from 0 to (4,294,967,295) for unsigned integers, or from (-2,147,483,648) to (2,147,483,647) for signed integers.
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.
