Computer fundamental MCQ Questions and answers- Technical Aptitude

Software piracy refers to the illegal copying of software. It often uses the Internet. Although the Internet gets a bad rap as a source of viruses, you're no more likely to contract a virus from the Web than you are from packaged software.

Mozilla Firefox or simply Firefox is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface.

The main difference between a mainframe computer and a supercomputer is their design purpose and workload.

A mainframe computer is designed to handle thousands of users, applications, and transactions simultaneously. Its primary goal is to provide high reliability, availability, security, and continuous processing. Mainframes are widely used in banks, airlines, insurance companies, government departments, and large enterprises, where millions of transactions must be processed accurately and efficiently every day.

A supercomputer, on the other hand, is designed to solve a small number of highly complex computational problems as quickly as possible. It delivers extremely high processing speed by performing billions or trillions of calculations per second. Supercomputers are commonly used for weather forecasting, climate modeling, scientific research, space exploration, nuclear simulations, artificial intelligence, and molecular research.

Thus, supercomputers focus on maximum computational speed for a few intensive tasks, while mainframes focus on processing a large number of programs, users, and transactions concurrently. This is the fundamental distinction between the two types of computers.

Why the other options are incorrect:

Option A: The physical size of a supercomputer is not the defining difference. Both mainframes and supercomputers can occupy large spaces depending on their configuration.

Option B: This statement is incorrect because supercomputers are not necessarily smaller than mainframes, and size is not the basis for classification.

Option D: This option reverses the actual roles. Mainframes are designed to execute many programs and transactions simultaneously, while supercomputers are designed to execute a few computationally intensive programs at maximum speed.

Exam Tip: Remember this simple rule: Supercomputer = Maximum Speed (Few Complex Tasks), whereas Mainframe = Maximum Throughput (Many Users & Transactions Simultaneously). This is one of the most frequently asked conceptual differences in Computer Fundamentals.

In Windows, the Recycle Bin is a folder or directory where deleted items are temporarily stored. Deleted files are not permanently removed from the hard drive but are sent instead to the Recycle Bin, unless they are too large. The files in the Recycle Bin can be restored to their original location. They cannot be used directly while they are in the Recycle Bin.

The correct answer is likely Option A: Office 2024, but it depends on when you are reading this!

Here's why:
* Microsoft Office gets updated regularly.
* "Latest" means the most recent version available to purchase or subscribe to.
* Office 2016, 2019 and 2020 are older versions.
* Office 2024 is the most recent one compared to other options. If a newer version comes out after Office 2024, then the correct answer would change.
* Always check the official Microsoft website for the absolute latest version.
* Option E is only correct if no office 2024 available in option.

A keyboard is a peripheral device that allows a user to input text and commands into a computer.

Unlike a projector, scanner, or printer, a keyboard is typically directly connected to a single computer and cannot be shared over a network.

Projectors, scanners, and printers can be configured to be shared across a network, allowing multiple users to access them.

Laser scanners work the same way as pen-type readers except that they use a laser beam as the light source and typically employ either a reciprocating mirror or a rotating prism to scan the laser beam back and forth across the barcode.

An essential difference between the operating system that runs a typical desktop computer and the operating system that runs a typical PDA is that the desktop OS can run several programs simultaneously whereas the PDA OS cannot.

A set of information that defines the status of resources allocated to a process of process description. A process description is a set of information that describes the characteristics of a process in terms that will enable its effective installation, commissioning, operation, control and maintenance.
