Answer: A) Internet Explanation: Internet is not an operating system.

Answer: B) E Explanation:

Answer: B) Siemens m2/equivalent Explanation: Equivalent conductance is defined as the conductance of an electrolyte solution containing one gram equivalent of the electrolyte. It is equal to the product of specific conductance (k) of the solution and the volume (V) of the solution that contains one gram equivalent of the electrolyte.    λ = k x V   Unit of spceific conductance k is Siemens / m. Volume of the solution V is m3 Now, required equivalent conductance unit is Siemens.m2/equivalent .

Answer: B) The court decides which cases it will hear. In deciding cases, the chief justice’s vote counts as two votes. Explanation:

Answer: B) Rs. 500 Explanation: Let the amounts to be received by P, Q and R be p, q and r.p + q + r = 1200p = 1/2 (q + r) => 2p = q + r Adding 'p' both sides, 3p = p + q + r = 1200=> p = Rs.400 q = 1/3 (p + r) => 3q = p + r Adding 'q' both sides, 4q = p + q + r = 1200=> q = Rs.300 r = 1200 - (p + q) => r = Rs.500.

Answer: D) Emit Explanation: Here the given words represent synonyms. Exhibit and Display are synonyms for each other. Similarly, Send and Emit are synonyms for each other.   Hence, Exhibit : display :: send : Emit.

Answer: B) ROM and RAM Explanation: The main memory is defined as the central storage in a computer. (noun) An example of the main memory is where programs and data are kept when the processor is actively using them.   The main storage region of a computer, to which the central processor has immediate or direct access is of two kinds. They are :: RAM -- Random Access Memory ROM -- Read Only Memory.

Answer: D) First Generation Explanation: The First Generation Computers size was very large.    Since the First generation computers used 1000s of vacuum tubes that required lot of space made them gigantic in size. Single transistor could replace 1000 vacuum tubes and a single IC chip replaced 1000s of transistors made computers smaller and more speedy.   It is obvious that computers developed with more power, reliability, speed and smaller sizes due to the enhancement of technology.
