Question 1 of 20
Which specific type of image is drawn by the precise laser beam on the rotating photoreceptor drum during the electro-photographic printing process?
Question 2 of 20
In the central processing architecture, which hardware unit strictly takes on the responsibility of decoding the instruction after it has been placed in the Instruction Register (IR)?
Question 3 of 20
The dynamic sequence—starting from the ingestion of raw data, moving through internal manipulation, and concluding with the presentation of formatted results—is universally encapsulated by which fundamental acronym?
Question 4 of 20
Match List-I (Computer Generation) with List-II (Programming Languages): List-I a. First Generation b. Second Generation List-II I. Assembly Language, COBOL, and FORTRAN II. Machine Language (Binary 0s and 1s)
Question 5 of 20
Under what strict, explicit conditions does a modern computer guarantee 100% absolute accuracy during its execution of calculations?
Question 6 of 20
Match the fundamental hardware or software component in List I with its strict operational mechanism in List II. List I a. Dynamic RAM (DRAM) b. Static RAM (SRAM) c. Erasable Programmable ROM (EPROM) d. Secondary Storage List II I. Requires targeted Ultraviolet (UV) light exposure for memory erasure II. Inaccessible directly by the CPU; requires intermediate transfer to RAM III. Utilizes transistor logic (flip-flops) yielding ultra-fast, static buffering IV. Relies on capacitors and demands a continuous electrical refreshing cycle Choose the most accurate mapping:
Question 7 of 20
Assertion (A): Computers from the IBM 7094 series were inherently more reliable and energy-efficient than the ENIAC. Reason (R): The IBM 7094 models utilized solid-state transistors instead of fragile vacuum tubes for their primary logic hardware.
Question 8 of 20
Assertion (A): It is significantly more expensive to manufacture RAM per gigabyte compared to ROM. Reason (R): RAM utilizes complex architecture that allows the CPU to seamlessly and rapidly Read from and Write to it at any time.
Question 9 of 20
Which of the following is an accurate example of an Optical Disc used as a storage device?
Question 10 of 20
What is the correct chronological sequence of the standard Instruction Cycle managed by the Control Unit?
Question 11 of 20
A modern processor operating in the 'picosecond' range is processing data at which fraction of a second?
Question 12 of 20
Along with Primary Cache and RAM, which other broad category of storage is explicitly included within the comprehensive 'Memory Unit' block of a standard computer architecture?
Question 13 of 20
Assertion (A): The Instruction Register (IR) must hold the current instruction before the CPU can determine the required execution steps. Reason (R): The Control Unit decodes the instruction specifically while it is being held in the Instruction Register. Select the correct answer from the codes given below:
Question 14 of 20
Which of the following input technologies is primarily utilized by the global banking industry to securely process and clear cheques?
Question 15 of 20
Given below are two statements, one labeled as Assertion (A) and the other as Reason (R): Assertion (A): Linux is highly revered by IT professionals. Reason (R): Linux provides architectural stability, high security, and a robust Command Line Interface (CLI). Choose the most appropriate answer:
Question 16 of 20
Which defining generation of computer history saw the monumental introduction of keyboards and monitors, replacing older methods like punched cards?
Question 17 of 20
In the foundational theory of computer science, how is the boundary or distinction between Hardware and Software characterized?
Question 18 of 20
Which specific hardware unit is exclusively targeted by the Control Unit's control signals to execute mathematical and logical manipulation?
Question 19 of 20
If computing architecture advances from speeds measured in microseconds to picoseconds, what is the exact mathematical shift in the fractional measurement of a second?
