Q:

which of the following represents a set of properties that guarantee that database transactions are processed reliably in computer science ?

A) Buffer Cache B) ACID
C) Foreign Key D) None
 
Answer & Explanation Answer: B) ACID

Explanation:

ACID means (Atomicity, Consistency, Isolation, Durability) is a set of properties of database transactions intended to guarantee validity even in the event of errors, power failures, etc.

In the context of databases, a sequence of database operations that satisfies the ACID properties and, thus, can be perceived as single logical operation on the data, is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction.

Q:

A wire of copper having length I and area of cross-section A is taken and a current / is flown through it. The power dissipated in the wire is P. If we take an aluminium wire having same dimensions and pass the same current through it, the power dissipated will be

A) P B) < P
C) > P D) 2P
 
Answer & Explanation Answer: C) > P

Explanation:

Aluminum has a resistivity varying from 2.65 to 2.82 × 10−8 Ω m.The resistivity of copper is generally given as: 1.72 x 10-8 Ω.m.So, since resistivity of aluminium is higher than that of copper, so Power dissipated will be greater than P. this is because rest of the factors (l, A and i) are constant.
