<span>Ordering of tuples in a Relation : </span>The tuples
are not considered to be in order, even though they appear to be in the tabular
form. The Ordering of attributes in a relation schema R and of values
within each tuples - We consider the attributes in R(A1, A2, .., An) and the
values in t=<v1, v2, .., vn> to be in order. Values in a tuple : All values are considered to be indivisible (atomic). A
special null value is used to represent values that are unknown or not applicable
to certain tuples.
A mouse is considered that out of the options listed.
Answer: D. Turing conceived the structure of a programmable computer.
Explanation: The passage describes how Alan M. Turing described the theoretical aspect of a programmable computer. There is no reference to a physical machine or Turing working on an actual (physical) computer.
The Turing machine, although it does sound like a physical computer was an abstract idea, conceived in mathematical form of what a programmable machine would be like. Alan Turing is considered one of the founding fathers of theoretical computer science.
