Question

what do you mean by :-
(a) Fields
(b) Tuples​

Answer 1

1)A field is an area in a fixed or known location in a unit of data such as a record, message header, or computer instruction that has a purpose and usually a fixed size. In some contexts, a field can be subdivided into smaller fields.

2)In database systems, fields are the smallest units of information you can access. In spreadsheets, fields are called cells. Most fields have certain attributes associated with them. For example, some fields are numeric whereas others are textual, some are long, while others are short.

3)Programming basics. A tuple is a data structure that is an immutable, or unchangeable, ordered sequence of elements. Because tuples are immutable, their values cannot be modified. As a general rule, tuples use less memory than a list or array.

4).....1) In programming languages, such as Lisp, Python, Linda, and others, a tuple (pronounced TUH-pul) is an ordered set of values. ... In some languages, tuples can be nested within other tuples within parentheses or brackets or other delimiters. Tuples can contain a mixture of other data types.

i hope it helpfull to you

Answer 2

Answer:

• A field is an area in a fixed or known location in a unit of data such as a record, message header, or computer instruction that has a purpose and usually a fixed size. In some contexts, a field can be subdivided into smaller fields.

• A tuple is a finite ordered list (sequence) of elements. An n-tuple is a sequence (or ordered list) of n elements, where n is a non-negative integer. There is only one 0-tuple, an empty sequence, or empty tuple, as it is referred to.
