What is the smallest unit of addressable memory?

byte
Historically, eight bits comprised a byte, which in turn is the smallest addressable unit of information or memory.

What is a bit Why are 8 bits considered as 1 byte Why not 7 bit or 9 bit?

Bytes is the number of bits required to encode a character in a computer. That is why 8 bits is 1 byte.

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. This sentence, for instance, is 41 bytes. That’s easily countable and practical for our purposes.

What does it mean for memory to be byte-addressable?

Byte addressable memory refers to architectures where data can be accessed and addressed in units that are narrower than the bus. An eight-bit processor like the Intel 8008 addresses eight bits, but as this is the full width of the bus, this is regarded as word-addressable.

Why is a byte The smallest addressable?

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.

What is the smallest addressable memory and what does it store?

If happen to be working on such a processor, words are the smallest addressable unit. In nearly all case these days a WORD will be the same as a byte. (Although some assembly languages use WORD to indicate two-bytes).

Why are there 7 bits in a byte?

The 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.

How do you write kilobytes?

In the International System of Units (SI) the prefix kilo means 1000 (103); therefore, one kilobyte is 1000 bytes. The unit symbol is kB.

What is the smallest unit of information?

Bit is the smallest unit of information a computer can understand. A bit has a single binary value, either 0 or 1.

What is the difference between byte addressable and word addressable?

Byte addressable means that every byte has its own unique address and can be accessed. Word addressable means that every word has its own unique address and can be accessed.

What is the relationship between a word and the addressable unit of memory?

Now we can clearly state the difference between Byte Addressable Memory & Word Addressable Memory. When the data space in the cell = 8 bits then the corresponding address space is called as Byte Address. When the data space in the cell = word length of CPU then the corresponding address space is called as Word Address.
