Consider the set H of all 3 × 3 matrices of the type: $\begin{bmatrix} a&f&e\\ 0&b&d\\ 0&0&c\\ \end{bmatrix}$ where a, b, c, d, e and f are real numbers and $abc ≠ 0$. Under the matrix multiplication operation, the set H is: (a) a group (b) a monoid but not a group (c) a semigroup but not a monoid (d) neither a group nor a semigroup

Let R be the relation on the set ‘N’ of strictly positive integers, where strictly positive integers x and y satisfy x R y iff x^2 – y^2 = 2^k for some non-negative integer k. Which of the following statement is true with respect to R? I think it’s just reflexive, because it obeys reflexive conditions.

I've some elementary doubts regarding Foreign keys (referential integrity) : Can a foreign key consist of a collection of attributes - ie. can two or more columns collectively form a foreign key? If foreign key refers to a column within the same ... that has either: Multiple candidate keys Composite candidate keys Overlapping candidate keys If possible, please provide an example. Thank You.!

Consider a $128 \times 10^3$ bits/second satellite communication link with one way propagation delay of $150$ milliseconds. Selective retransmission (repeat) protocol is used on this link to send data with a frame size of $1$ kilobyte. Neglect the transmission time of acknowledgement. The minimum number of bits required for the sequence number field to achieve $100 \%$ utilization is ________.
