A. Short Answer Type Questions

1. Name any two hardware components that are located inside the CPU box.

The CPU box, also known as the central processing unit (CPU) or motherboard, is the main circuit board of a computer that connects all hardware components together. Two essential hardware components located inside the CPU box are:

RAM (Random Access Memory): RAM is a type of computer memory that temporarily stores data and applications while a computer is running. It is a volatile memory technology, meaning that its contents are lost when the computer is powered off. RAM is used to store data that the CPU uses to perform calculations and execute instructions.
GPU (Graphics Processing Unit): A GPU is a specialized electronic circuit designed to quickly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. Modern GPUs are very efficient at performing matrix operations, making them well-suited for tasks such as scientific simulations, data compression, and machine learning.

2. Define Smart Board.

A Smart Board is an interactive whiteboard that combines the features of a traditional whiteboard with the capabilities of a computer. It is a digital display surface that allows users to write, draw, and interact with digital content using a stylus or their fingers. Smart Boards are designed to enhance collaboration, engagement, and learning in educational settings, as well as in business and professional environments.

Smart Boards typically consist of a large, high-resolution display screen, a computer or tablet, and a stylus or other input device. They often come with software that allows users to create and edit digital content, such as presentations, lessons, and notes. Smart Boards can also be connected to the internet, enabling users to access a wide range of digital resources and tools.

3. Can a mouse and keyboard be wireless?

Yes, a mouse and keyboard can be wireless. Wireless mice and keyboards use radio frequency (RF) or Bluetooth technology to communicate with a computer or other device without the need for cables. This provides greater flexibility and convenience, as users can move around freely while working or gaming without being tethered to their computer.

Wireless mice and keyboards are available in a range of styles and designs, from compact and portable to full-size and ergonomic. They often come with rechargeable batteries, which can provide several months of use on a single charge. Some wireless mice and keyboards also offer advanced features, such as gesture recognition, customizable buttons, and adjustable sensitivity.

4. What do you mean by a disk drive?

A disk drive is a type of storage device that reads and writes data to a physical medium, such as a hard disk drive (HDD) or solid-state drive (SSD).

Disk drives come in various forms, including:

Hard Disk Drive (HDD): A traditional disk drive that uses spinning disks and mechanical heads to read and write data.
Solid-State Drive (SSD): A faster and more reliable disk drive that uses flash memory to store data.
Optical Disk Drive (ODD): A disk drive that reads and writes data to optical discs, such as CDs, DVDs, and Blu-ray discs.

5. What does CD-RW stand for?

CD-RW stands for Compact Disc-Recordable, Re-Writable. It is a type of optical disc that can be written to and re-written multiple times. CD-RW discs are used to store data, music, and video content, and are often used for backing up important files or creating custom music mixes.

CD-RW discs are similar to CD-R (Compact Disc-Recordable) discs, but they have the added ability to be re-written. This makes them a popular choice for applications where data needs to be updated or modified frequently.

6. What is a USB port?

A USB (Universal Serial Bus) port is a type of connector that allows devices to be connected to a computer or other device. USB ports are used to transfer data, power devices, and provide a means of communication between devices.

USB ports come in various types, including:

USB-A: A standard USB port that is used to connect devices to a computer.
USB-B: A smaller USB port that is used to connect devices to a computer or other device.
USB-C: A newer type of USB port that is faster and more versatile than traditional USB-A and USB-B ports.

USB ports are widely used in computers, smartphones, tablets, and other devices, and are an essential component of modern technology.
