How many possible values can we have with 8 bits?
Answer: 00000000 11011011 Explanation: A byte is 8 bits and each bit is either a 0 or 1. Question 2: How many possible values can we have with 8 bits? Answer: 256 Explanation: …
What is the maximum number a byte can represent?
Without getting into two's complement: 2^8 (since a byte is 8 digits and can have 1 of 2 values) = 256, so the most individual values a byte can represent is 256. so, representing the numbers -128 to -1 is half our range.

How many bits are in a byte?
A byte can be defined as one that is composed of eight bits of zeros and ones. 2^8 = 256. Bits use the binary system, which is also known as the base-2 numeral system. So 2^8 allows us 256 values from 0 to 255. 3) UTF-8 can store a character in more than one byte.

Is all 0 a valid byte?
A byte is a group of 8 bits. A bit is the most basic unit and can be either 1 or 0. A byte is not just 8 values between 0 and 1, but 256 (28) different combinations (rather permutations) ranging from 00000000 via e.g. 01010101 to 11111111 .
Which of these are valid byte?
A byte is made up of binary bits. So as long as it's a sequence of 1's and 0's. It's valid.
How many zeros are in a byte?
A byte can represent any value from 00000000 through 11111111, for a total of 256 different possible values. Each digit in a byte can be thought of as representing an individual switch that is either off (zero) or on (one).
How many digits is a byte?
eight binary digitsData is often expressed in bytes, which are composed of eight binary digits. Bytes are used to represent all sorts of data, including letters, numbers and symbols.
How many bytes is a byte?
8 bitsThe byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures....byteSymbolB or o (when 8 bits)2 more rows
Is UTF-8 valid?
Valid UTF8 has a specific binary format. If it's a single byte UTF8 character, then it is always of form '0xxxxxxx', where 'x' is any binary digit. If it's a two byte UTF8 character, then it's always of form '110xxxxx10xxxxxx'.
What is the largest byte possible?
A yottabyte is the largest unit approved as a standard size by the International System of Units (SI). The yottabyte is about 1 septillion bytes -- or, as an integer, 1,000,000,000,000,000,000,000,000 bytes. The storage volume is equivalent to a quadrillion gigabytes (GB) or a million trillion megabytes.

How many possible values can 8 bits have?
256With 8 bits, the maximum number of values is 256 or 0 through 255. Table 5.1 gives the number of bits in a binary number and the maximum number of states that can be represented. G, gigabits = 1,0737,41,824; K, kilobits = 1024; M, megabits = 1,048,576.
Why did UTF 8 replace the ASCII?
Why did UTF-8 replace the ASCII character-encoding standard? UTF-8 can store a character in more than one byte. UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte. This allowed us to represent a lot more character types, like emoji.
What is the highest decimal value in a byte?
As we know there are 8 bits in one byte. So the largest value can be calculated by using 2n - 1, where n is the number of bits. 28 - 1 = 255. Hence 255 is the highest decimal value you can have for one byte.

How many byte characters can UTF-8 store?
UTF-8 can store a character in more than one byte.
How many bits are in a byte?
A byte can be defined as one that is composed of eight bits of zeros and ones.
What is the binary value of C?
The binary value of the ASCII letter "c" is 0110 0011. Using the handy chart that we learned in the lesson, convert this number to its decimal value. You'll need to use some math for this question.
How many zeros are in a byte?
A byte is composed of eight bit s of zeros and ones.
How many bytes can UTF-8 store?
UTF-8 can store a character in more than one byte. UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte. This allowed us to represent a lot more character types, like emoji.

How many ternary bits are in a byte?
I’ll call a byte a collection of 8 ternary bits with implicit highest zeroes. This way all of these are valid.
How many bytes are in 1K memory?
Early on, a convenient shorthand for expressing the sizes of memory was to call 1,024 bytes “1K”, 2,048 bytes 2K, and so on. This was by analogy to the metric system which calls 1,000 of a unit a kilo<unit>, and 1,024 is close enough to 1,000. Engineers and programmers implicitly understood that when talking about memory, a K wasn’t 1,000, it was the next full amount of a power of two, because there would be no point in leaving out the last 24 addresses of a 1K chip. This was all fine when memory was measured out in kilobytes, because the discrepancy wasn’t worth worrying about.
What is the range of numbers in ASCII?
For example, ASCII, one of the earliest popular encodings, used 7 bit chunks to represent a range of 128 numbers, encoded in binary. As is often the case in computers, the counting starts at 0, not 1, so the full range goes from 0 to 127:
How many addresses can a memory chip have?
If we have 10 address pins on our memory chip, we can address exactly 1,024 addresses within the chip. It can’t be 1,025, because that would require 11 wires, and if we have 11 wires, we might as well “fill” the chip with the maximum amount of memory that can address, which is 2,048 bytes.
How many addresses can you have on an address bus?
If the address bus had one wire, you could access exactly two addresses, call them address 0 and address 1, depending on whether the address wire was low (0) or high (1). If we have two wires, we can have 4 addresses. 3 wires, 8, 4 wires 16 and so on. Each additional wire doubles the number of addresses we can access.
What is the correct prefix for giga?
While I find it ugly, I accept that the correct prefixes are giga- (G) for 10^9, and gibi- (Gi) for 2^30. The misuse of giga- (and kilo-, mega-)in the context of directly accessible computer main memory is tolerable, but not encouraged.
Do you need to know the size of a linked list?
In Linked Lists we don’t need to know the size in advance.
