What is a 8 bits 1 byte?
On almost all modern computers, a byte is equal to 8 bits. Large amounts of memory are indicated in terms of kilobytes, megabytes, and gigabytes. A disk that can hold 1.44 megabytes, for example, is capable of storing approximately 1.4 million characters, or about 3,000 pages of information.
How many bytes is Wchar_t?
2 bytes
wchar_t is 2 bytes (UTF16) in Windows.
How many bits is a quadword?
64 bits
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).
Is a word 16 or 32 bits?
They used word for a 16-bit quantity, while longword referred to a 32-bit quantity. Data structures containing such different sized words refer to them as WORD (16 bits/2 bytes), DWORD (32 bits/4 bytes) and QWORD (64 bits/8 bytes) respectively.
What is after petabyte?
Therefore, after terabyte comes petabyte. Next is exabyte, then zettabyte and yottabyte.
Why is a byte 8 bits and not 10?
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.
What is the size of wchar_t in 16-bit compiler?
The wchar_t type is an implementation-defined wide character type. In the Microsoft compiler, it represents a 16-bit wide character used to store Unicode encoded as UTF-16LE, the native character type on Windows operating systems.
What does wchar_t stand for?
wide character
Up vote 11. wchar_t is a wide character. It is used to represent characters which require more memory to represent them than a regular char . It is, for example, widely used in the Windows API.
What is a group of 16 bits called?
word
The correct answer is a word. A combination of 16 bits is called a word.
What is 64-bit system?
An operating system that is designed to work in a computer that processes 64 bits at a time. A 64-bit operating system will not work in a 32-bit computer, but a 32-bit operating system will run in a 64-bit computer. See 64-bit computing.
What is the word length on a 16-bit processor?
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.
How many octets are in a byte of data?
An octet would also be 8, so the answer would be 1 (8/8). An Octal is a group of 3 bits, 8/3 = 2 1/3, so there are two and one third Octals in a Byte. MS in Data Science online—No GRE Required.
What does an octet string mean in programming?
Octet string = sequence of bytes. Also, see Wikipedia. “Octet” is standardese for “8-bit byte”. It’s supposed to be a less ambiguous term compared to just “byte”, because some platforms have bytes of different width (not sure if there are any are still remaining, but they used to exist).
How many octets are in a six bit ASCII code?
The six bit ASCII code was represented as two groups of three bits and briefly gave rise to a base 8 notation they called octal which was terrible for everyone and still hangs around today, though it is thankfully falling by the wayside. Gradually, the awkward seven bit set of characters had an extra bit added and characters became eight bits wide.
How are pictures stored in an octet string?
There are javascript using BASE-64 encoding used to store pictures in Strings. The larger alphabet, in this case(I think ) A-Z,a-z,0-9, the less data needs to be transferred. every octet has 256 different possible values, and are to be stored in an alphabet of 62 letters, clearly one needs to use more than one letter / octet.
