In computing, a word is the natural unit of data used by a particular processor design.The number of bits in a word (the word size, word width, or word length) is an important characteristic of any specific processor design or computer architecture.

What is word in memory?
A group of memory bits in a RAM or ROM block.In Verilog HDL, a memory word is a register in a memory (that is, RAM or ROM) block that contains the same range of bits as the other registers in the memory. For example, the memory reg [5:0] EXAMPLE [0:2] defines 3 memory words, each containing a bit range of 5 to 0 .
What is computer easy word?
A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web.
What is a word in binary?
Quick Reference. A binary word of length n is a string of n binary digits, or bits. For example, there are 8 binary words of length 3, namely, 000, 100, 010, 001, 110, 101, 011 and 111.
How many bits make a word?
16 bits
Fundamental Data Types
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).
What is word in PLC?
A word refers to the size of data the processor handles. This will vary by PLC model. If the PLC uses a 16 bit processor a word refers to 16 contiguous bits (2bytes). A 32 bit processor uses a 32 bit word. Older PLCs used 8 bit words, there are still alot of these out there.
How are words stored in a computer?
Text is stored on a computer by first converting each character to an integer and then storing the integer. For example, to store the letter `A’, we will actually store the number 65; `B’ is 66, `C’ is 67, and so on. The conversion of letters to numbers is called an encoding.
What are the 4 types of computer?
The four basic types of computers are as under: Supercomputer. Mainframe Computer. Minicomputer.
- Analog Computer.
- Digital Computer.
- Hybrid Computer.
What are the 7 types of computers?
Types of computers
- Supercomputer.
- Mainframe.
- Server Computer.
- Workstation Computer.
- Personal Computer or PC.
- Microcontroller.

What is a computer for kids?
A computer is a. device for working with information. The information can be numbers, words, pictures, movies, or sounds. Computer information is also called data. Computers can process huge amounts of data very quickly.
Why is a word 2 bytes?
If a character is 8 bits, or 1 byte, then a WORD must be at least 2 characters, so 16 bits or 2 bytes.
What is word length in computer?
The word length of the processor in a computer refers to the maximum number of bits it can take as input. It is the number of bits processed by a computer CPU in a single pass. The computer further takes this input for process and gives the output.
What is opposite word?
The word which is a pronoun that means what one? It may also be used to introduce restrictive and nonrestrictive clauses. There are no categorical antonyms for this word.
What is a bit word?
A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1.In many systems, four eight-bit bytes or octets form a 32-bit word. In such systems, instruction lengths are sometimes expressed as full-word (32 bits in length) or half-word (16 bits in length).
What is the name of 4 bit data?
From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. Bytes are a pretty common buzzword when working in binary.
What are 4 bits called?
nibble
In computing, a nibble (occasionally nybble or nyble to match the spelling of byte) is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade. In a networking or telecommunication context, the nibble is often called a semi-octet, quadbit, or quartet.
Is a word 16 or 32 bits?
In x86 assembly language WORD , DOUBLEWORD ( DWORD ) and QUADWORD ( QWORD ) are used for 2, 4 and 8 byte sizes, regardless of the machine word size. A word is typically the “native” data size of the CPU. That is, on a 16-bit CPU, a word is 16 bits, on a 32-bit CPU, it’s 32 and so on.
What is difference between word and integer?
Integer is a signed value 16-bit (+32767 to -32768 range), WORD is an unsigned 16-bit value (0 to +65535 range).
How many words are in a PLC?
Most PLCs use 16-bit words. a 16-bit unsigned integer (0 to 65,535). a 16-bit signed integer (-32,768 to 32,767). 16 individual bits (such as a group of boolean values).
Which is word addressable RAM?
A memory word is certain bytes that bidirectional data bus can carry at a time.And such memory are called word addressable memory. In a 32 bit machine, size of the data bus is 32 bits or 4 bytes. So, a 32 bit machine has word size of 4 bytes.
What is digital word?
1 : relating to or using calculation directly with digits rather than through measurable physical quantities. 2 : of or relating to data in the form of numerical digits digital images digital broadcasting. 3 : providing displayed or recorded information in numerical digits from an automatic device a digital watch.
