Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In historical computer architecture contexts, the expected life cycle of a major processor architecture was often cited as approximately 7 years before being superseded by newer technology.

Multiple choice

What is the name given to the molecular scale Computer?

  1. Femtocomputer

  2. Nanocomputer

  3. Supercomputer

  4. Microcomputer
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A nanocomputer is a computer at the nanometer scale, often involving molecular or atomic-level components. This is distinct from microcomputers, which use integrated circuits.

Multiple choice

The unit of speed used for super computer is

  1. KFLOPS

  2. MFLOPS

  3. GFLOPS

  4. All of the above.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Supercomputer performance is measured in FLOPS (Floating Point Operations Per Second). GFLOPS (GigaFLOPS) is a common unit for supercomputer speed.

Multiple choice

Which of the following Processor is based on RISC Concept?

  1. Intel 80486.

  2. Intel 80586.

  3. Intel P6.

  4. None of the above.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Intel P6 microarchitecture, introduced with the Pentium Pro, incorporated RISC-like features such as instruction decoding into micro-ops. The 80486 and 80586 (Pentium) are primarily CISC architectures.

  3. TRS- 80 Model I.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The MITS Altair 8800, released in 1975, is widely recognized as the first successful microcomputer sold as a kit for hobbyists.

Multiple choice

The ENIAC

  1. Was Totally Electronic.

  2. Was the size of a personal computer.

  3. Was programmed by punched cards.

  4. Both (1) and (3).
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

ENIAC (Electronic Numerical Integrator and Computer) was the first general-purpose, electronic, digital computer. It used vacuum tubes and was programmed by manually setting switches and cables.
