Correct Answer

(C) LIFO

Explanation

Solution: Hardware LIFO memory is seldom used in modern computers. Short for last in, first out, LIFO is a method of processing data where the data last received is the first to be sent out after processed.

[#873] An IC contains 50 gates each of which consists of 6 components. Its belong to
Correct Answer

(C) MSI

Explanation

Solution: An IC contains 50 gates each of which consists of 6 components. Its belong to MSI, Medium Scale Integration or (MSI) - between 10 and 100 transistors or tens of gates within a single package and perform digital operations such as adders, decoders, counters, flip-flops and multiplexers.

[#874] Which gate only sends one through if neither of its terminals receives a pulse.
Correct Answer

(B) NOR

Explanation

Solution: NOR gate is a digital logic gate. It implements logical NOR. It behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0). If one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator. It can also be seen as an AND gate with all the inputs inverted. NOR is a functionally complete operation. It combinations of NOR gates can be combined to generate any other logical function.

[#875] Which is a basic technique, using activity networks.
Correct Answer

(A) CPA

Explanation

Solution: Basically a CPA network is a network that focuses mainly on Cost-Per-Action or Cost-Per-Acquisition advertising. It's a type of Affiliate Marketing, but often focuses on leads over sales, but not exclusively. It's a little complex, but its a great way to generate a lot of leads or sales really fast.
