Computer fundamental MCQ Questions and answers- Technical Aptitude

The correct answer is Option C: WORM disk.
Let's break down why:

WORM stands for "Write Once Read Many".
This means you can write data to the disk once, and then read that data many times.
It's a type of optical storage where the data is permanently recorded.

Why not the other options?
Digital paper: This is still a developing technology and not a standard optical storage medium.
Magneto-optical disk: These are rewritable, not write-once.
CD-ROM disk: CD-ROMs are typically pre-recorded or mastered, and while they are read-only for the user after creation, the creation process itself is not "write-once" in the same way a WORM disk is. Furthermore, CD-ROM is an older technology.
None of the above: WORM is a valid write-once optical storage media.

Therefore, a WORM disk best fits the description of a latest write-once optical storage media.

The data processing job expected to further decrease in the 1996s is that of Keypuncher. A keypunch is a device for precisely punching holes into stiff paper cards at specific locations as determined by keys struck by a human operator.

A computer has no more sense than a light switch. Switches allow devices to share and transfer data, enabling communication between devices on the network. Switches work by processing packets of data and routing them to the intended destination(s).

ENIAC (Electronic Numerical Integrator And Computer) was the world’s first general-purpose computer. ENIAC was designed and built for the United States Army to calculate artillery firing tables. However, it was ENIAC’s power and general-purpose programmability that excited the public’s imagination. When it was announced in 1946, ENIAC was referred to in the media as a “giant brain.”

A compiler is computer software that transforms computer code written in one programming language (the source language) into another programming language (the target language). Compilers are a type of translator that support digital devices, primarily computers. The name compiler is primarily used for programs that translate source code from a high-level programming language to a lower level language (e.g., assembly language, object code, or machine code) to create an executable program.

A logic gate is an electronic circuit which Makes logic decisions. A Digital Logic Gate is an electronic device that makes logical decisions based on the different combinations of digital signals present on its inputs.

Identity the advantages that Micro Channel Architecture offers over ISA. Automatic System Configuration, Less Interference, Multiple device handling (the system allows expansion boards to take complete of the bus for certain operations), Greater data transfer rates. And all of the above in ISA.

Computer scientists are exploring the possibility of culturing bacteria to create living chips which have digital electronic properties. The chips called in biochips. A biochip is much like a computer chip but instead of performing a multitude of mathematical operations per second, it performs biological reactions such as decoding genes and finding contaminations in a few seconds.

A buffer is a storage device used to compensate for a difference in rate of data flow, or time of occurrence of events, when transmitting data from one device to another.

In latest generation computers, the instructions are executed both sequentially an parallely. In computer science, an instruction is a single operation of a processor defined by the processor instruction set.
