Show Answer Key & Explanations
Step-by-step solution for: Computer Worksheet activity for Grade 3
Let's go through each statement one by one and determine whether it is True or False, with explanations for clarity.
---
✔ True
*Explanation:* A microcomputer (like a personal computer) is typically designed for individual use, as opposed to mainframes or servers that serve multiple users.
---
✘ False
*Explanation:* Modern computers can perform billions of operations per second (measured in GHz). Saying "one operation per second" is extremely slow and outdated.
---
✘ False
*Explanation:* The Arithmometer was invented by Charles Xavier Thomas de Colmar in the 1820s. John Napier is known for inventing Napier’s Bones, a calculating tool, not the Arithmometer.
---
✘ False
*Explanation:* IBM Deep Blue was a famous chess-playing supercomputer, but it is not the fastest in the world. As of recent years, the fastest supercomputers are like Fugaku (Japan) or Frontier (USA). Deep Blue is outdated.
---
✔ True
*Explanation:* Embedded computers are specialized computing systems embedded within larger devices. They often use microcontrollers (a type of microprocessor with integrated memory and I/O), so they are commonly referred to as such.
---
✘ False
*Explanation:* Ada Lovelace is considered the first computer programmer, not the inventor. She wrote algorithms for Charles Babbage’s Analytical Engine. The inventor of the first mechanical computer-like device is usually credited to Charles Babbage.
---
✔ True
*Explanation:* Yes, digital cameras contain small embedded systems that process images, manage settings, and store data—these are examples of embedded computers.
---
✔ True
*Explanation:* This is fundamental to networking. Computers connect via networks (Wi-Fi, Ethernet, etc.) to share data and resources.
---
✘ False
*Explanation:* Computers store both instructions (programs) and data (such as text, images, numbers, etc.). Memory holds both types.
---
✔ True
*Explanation:* That’s a standard definition: computers process raw data into useful information through computation and storage.
---
✔ True
*Explanation:* Charles Babbage is widely regarded as the Father of the Computer due to his design of the Analytical Engine, which had features resembling modern computers (input, processing, storage, output).
---
✘ False
*Explanation:* A workstation is a high-performance computer used for technical or scientific applications (e.g., engineering, graphic design). It is not similar to embedded computers, which are small, specialized systems built into devices. Workstations are general-purpose, while embedded systems are dedicated and limited in scope.

1. A microcomputer is designed to be used by one person at a time.
✔ True
*Explanation:* A microcomputer (like a personal computer) is typically designed for individual use, as opposed to mainframes or servers that serve multiple users.
---
2. The computer can perform an operation in a second.
✘ False
*Explanation:* Modern computers can perform billions of operations per second (measured in GHz). Saying "one operation per second" is extremely slow and outdated.
---
3. The Arithmometer is invented by John Napier.
✘ False
*Explanation:* The Arithmometer was invented by Charles Xavier Thomas de Colmar in the 1820s. John Napier is known for inventing Napier’s Bones, a calculating tool, not the Arithmometer.
---
4. The fastest computer in the world is IBM Deep Blue.

5. Embedded computers are also called microcontrollers.
✔ True
*Explanation:* Embedded computers are specialized computing systems embedded within larger devices. They often use microcontrollers (a type of microprocessor with integrated memory and I/O), so they are commonly referred to as such.
---
6. Lady Augusta Ada is the first computer inventor.
✘ False
*Explanation:* Ada Lovelace is considered the first computer programmer, not the inventor. She wrote algorithms for Charles Babbage’s Analytical Engine. The inventor of the first mechanical computer-like device is usually credited to Charles Babbage.
---
7. A digital camera has an embedded computer.
✔ True
*Explanation:* Yes, digital cameras contain small embedded systems that process images, manage settings, and store data—these are examples of embedded computers.
---
8. Computers can communicate with other computers.
✔ True
*Explanation:* This is fundamental to networking. Computers connect via networks (Wi-Fi, Ethernet, etc.) to share data and resources.
---
9. Computers can only store instructions.
✘ False
*Explanation:* Computers store both instructions (programs) and data (such as text, images, numbers, etc.). Memory holds both types.
---
10. A computer is a device that is used to manipulate data into information.
✔ True
*Explanation:* That’s a standard definition: computers process raw data into useful information through computation and storage.
---
11. Charles Babbage is the Father of the Computer?
✔ True
*Explanation:* Charles Babbage is widely regarded as the Father of the Computer due to his design of the Analytical Engine, which had features resembling modern computers (input, processing, storage, output).
