The only certainty is that a char holds one byte. All other primitives are implementation dependant. However, you can determine the length of any type, including user-defined types, by using the sizeof() operator.
1 MB (megabyte) = 1048576 bytes (2^20)
In Access and in databases in general each field in a database table is of a certain data type. The data type determines what type of data a field can hold. A field of the text data type can hold text, a field of the number data type can hold numbers and a field of the data/time data type can hold date and time values.Access actively checks what type of data is entered into a field and Access will disallow the entry of data into a field that doesn't conform to the field's data type. Access won't allow you to put text into a field of the Number data type, for example.So, data types are a way to restrict the entry of data into a field. Internally, the database uses different strategies for the storage and retrieval of different data types.
data type refers to the kind of value that is held by a particular variable. For ex: an int variable contains integer value, a string holds a alpha numeric value etc. variable refers to the name of a value using which we can refer to this value. Ex: public int age = 28; here int is the data type and age is the variable.
Because each data type uses a certain number of "bits" to store their values, and thus are mathematically limited to the amount of data they can hold before losing information. You can think of an analogy of your mailbox and letters you receive. You can only fit so many letters into the mailbox before it physically cannot hold any more letters.
There is no single answer to this question. A byte is universally defined as a tuple of 8 bits (sometimes bytes are also called octets, therefore).However, a word commonly refers to the natural word for a given processor, that is the processor's preferred entity for arithmetic operations. The word is therefore typically defined by the processor's ALU width.Typical 8, 16 or 32 bit processors have 8, 16 or 32 bit words (containing 1, 2 or 4 bytes), respectively. Other processors have another word size, such as 3 bytes per word, or 8.In Windows programming, a word is often thought to refer to a 16 bit entity, mostly because the classic 32-bit Windows API makes frequent use of DWORD, a double-word, 32 bits or 4 bytes wide. However, these data types are not generally portable and are not recommended for use outside the specific context of this API.

Exactly 0 bytes
A stick of 512 megabytes of RAM can hold about 512 megabytes of data. It cannot, however, store it for long because it is volatile and is not designed to store data.
KB = Kilo(1000)byte A KB of data can hold 2^10 =1024 Bytes of Information
A data structure such as an array or a string can hold a number of bytes or characters in a storage medium. In programming, arrays store multiple values of the same type, while strings specifically hold sequences of characters. Additionally, files on disk or in memory can also serve as storage for bytes and characters, enabling data persistence and retrieval.
The number of texts that a 5GB storage can hold depends on the average size of each text message. A typical SMS text message is around 160 characters and can be roughly estimated to be about 140 bytes. Therefore, 5GB (which is approximately 5 billion bytes) can hold about 35 million text messages, assuming no other data is stored.

One megabyte (MB) holds approximately 1 million bytes of data. More specifically, it is often defined as 1,024 kilobytes (KB), with each kilobyte consisting of 1,024 bytes. This means that a single MB can store various types of data, such as a few high-quality images, several minutes of audio, or a small text document.
In the 8086 microprocessor architecture, each segment can contain 64 kilobytes (KB) of data. Since 1 KB is equal to 1024 bytes, this means each segment can hold 65,536 bytes. The four segments typically used are the code segment, data segment, stack segment, and extra segment, allowing the processor to manage different types of information efficiently within its 1 MB addressable memory space.
A megabyte can hold approximately 1 million bytes of data, which is equivalent to roughly 500 pages of plain text or a few minutes of audio or video.
When data first started getting put onto compact discs in 1985 (until which time their sole purpose was for music), a typical CD held 74 minutes of music, or 650 million bytes of data. Today, your typical standard CD-ROM holds 80 minutes of music and 700 million bytes of data.
Approx 700MB, or 700,000,000 bytes.
