COMPUTER | MCQs

Explanation

Hardware refers to the physical components of a computer system, including:

• Motherboard: The main circuit board that connects all hardware components together.
• Hard disk: A storage device that holds data and programs.
• Processor (CPU): The brain of the computer that executes instructions and performs calculations.

In addition to these three, hardware also includes other components such as:

• RAM (Memory)
• Power Supply
• Graphics Card
• Sound Card
• Keyboard
• Mouse
• Monitor
• Case

Explanation

Synchronization can occur in both hardware and software contexts to ensure that different components or processes operate in harmony.

Explanation

زیادہ فائلز اکٹھی بھیجنے کے لیے زیپ استعمال ہوتا ہے کیونکہ:

کمپریشن: زیپ فارمیٹ فائلز کو کمپریس کرتا ہے، جس سے ان کا سائز کم ہو جاتا ہے اور انہیں بھیجنا آسان ہو جاتا ہے۔

ایک ہی فائل: متعدد فائلز کو ایک ہی زیپ فائل میں اکٹھا کیا جا سکتا ہے، جس سے انہیں مینیج کرنا آسان ہو جاتا ہے۔

آسان شیئرنگ: چھوٹی سائز کی فائلز کو ای میل یا دیگر فائل شیئرنگ سروسز کے ذریعے آسانی سے بھیجا جا سکتا ہے۔

پاس ورڈ پروٹیکشن: زیپ فائلز کو پاس ورڈ کے ذریعے پروٹیکٹ کیا جا سکتا ہے، جو فائلز کی سیکیورٹی کو بڑھاتا ہے۔

Explanation

When referring to data or storage device, writing is taking information and moving it to an alternate location.

For example, saving data onto a diskette is the same as writing information to a diskette.

Explanation

The Arithmetic and Logic Unit (ALU) performs logical operations in the Central Processing Unit (CPU).

An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations.

Explanation

 To boot (to boot up, to start up or booting) a computer is to load an operating system (OS) into the computer's main memory or RAM.

Explanation

Explanation

  To play and hear sound on a computer, the following are required:

• Sound Card: A hardware component or integrated chip that processes audio signals and enables the computer to produce sound.
• Speakers: External or built-in devices that convert audio signals from the sound card into audible sound.

Explanation

The Arithmetic Logic Unit (ALU) and the Control Unit (CU)

They are both components of the Central Processing Unit (CPU), which is the brain of a computer

Explanation

Both software and physical parts work together to transfer data in a computer system.

Software parts, such as operating systems, device drivers, and data transfer protocols, manage and direct data transfer.

Physical parts, like buses, ports, cables, network interface cards, and storage devices, physically move the data.
