Can a binary number have more than 8 bits?
Can a binary number have more than 8 bits?
A CPU with a capacity of 8 bits has a capacity of up to 11111111 in binary . If one more bit was added there would be an overflow error.
Why do computers use 256?
The general reasoning behind why 8, 256, and other numbers are important is that they are powers of 2, and computers run using a base-2 (binary) system of switches. ASCII encoding required 7 bits, and EBCDIC required 8 bits.
Why is it 255 and not 256?
The de facto standard of eight bits is a convenient power of two permitting the values 0 through 255 for one byte. That leads to 256 possible values, which are typically numbered 0 to 255.
What value does the 5 in 256 stand for?
5 is our tens digit. This means we have 5 sets of tens.
Why are computers based on 8 bits?
Originally Answered: Why are computers based on 8? 8 bits is a byte. Because computers are based on hardware, and hardware likes powers of two for binary logic. 8 bits was convenient: it holds a character in ASCII.
Why do we have 6 bit and 8 bit BCD code?
The earliest computers dealt with numeric data only, and made no provision for character data. Six-bit BCD was used by IBM on early computers such as the IBM 704 in 1954. This encoding was replaced by the 8-bit EBCDIC code when System/360 standardized on 8-bit bytes.
What is the largest decimal number you can represent using 7 binary bits?
127
What’s the smallest decimal number that you can represent with 4 bits?
8
What is the smallest decimal possible?
If we only have three digits to spare, the smallest possible number is 0.01. With four digits, it’s 0.001.
How many numbers can be represented with 3 bits?
Binary number representation
| Length of bit string (b) | Number of possible values (N) |
|---|---|
| 3 | 8 |
| 4 | 16 |
| 5 | 32 |
| 6 | 64 |
Why Ascii code is of 7 bit?
6 Answers. ASCII was indeed originally conceived as a 7-bit code. To be ASCII-compatible, a fixed-with encoding must encode all its characters using only one byte, so it can have no more than 256 characters. The most common such encoding nowadays is Windows-1252, an extension of ISO 8859-1.
What is the largest number that can be represented by 10 bits?
1024
How high can you count with 3 bits?
0 and 1 Two bits can strore four values 00, 01, 10, and 11 three bits can store eight values 000,001,010,011, 100,101,110 and 111. it means the combination of all the bits represents one value like 010 represents 2 and 101 represents 5.
What if humans had 8 fingers?
If we had 8 fingers per hand, then we would have evolved in a radically different environment. Almost all of the higher vertebrates in the world today have a multiple of five digits on each limb. Look at the skeleton of almost any creature and you’ll find a variation of five digits.
What is the largest number you can count on your 20 fingers?
Finger binary is a system for counting and displaying binary numbers on the fingers of one or more hands. It is possible to count from 0 to 31 (25 − 1) using the fingers of a single hand, from 0 through 1023 (210 − 1) if both hands are used, or from 0 to 1,048,575 (220 − 1) if the toes on both feet are used as well.
