Question 1. Which one of the following is an output device?
(a) Mouse
(b) Keyboard
(c) Speaker
(d) Pen drive
Answer: (c) Speaker
In simple words: A speaker is an output device because it sends out sound from the computer. Devices like a mouse and keyboard are used to put information into the computer, and a pen drive stores information. Output devices let us receive information from the computer.

🎯 Exam Tip: Identify the function of each device: input (sending data in), output (receiving data out), or storage (keeping data).

 

Question 2. Name the cable that connects CPU to the Monitor
(a) Ethernet
(b) VGA cable
(c) HDMI
(d) USB
Answer: (b) VGA cable
In simple words: The VGA cable is used to connect the computer's CPU to the monitor. It carries the video signals from the computer so you can see things on the screen. Many modern computers also use HDMI cables, which carry both video and sound.

🎯 Exam Tip: Be familiar with different types of cables and their specific functions in a computer system.

 

Question 3. Which one of the following is an input device?
(a) Speaker
(b) Keyboard
(c) Monitor
(d) Printer
Answer: (b) Keyboard
In simple words: A keyboard is an input device because you use it to type and put information into the computer. Speaker, monitor, and printer are all output devices because they show or give out information from the computer. Input devices convert our actions into digital data for the computer.

🎯 Exam Tip: Distinguish between input devices (send data to computer) and output devices (receive data from computer).

 

Question 4. Which one of the following is an example for wireless connections?
(a) Wi-Fi
(b) Electric wires
(c) VGA
(d) USB
Answer: (a) Wi-Fi
In simple words: Wi-Fi allows devices to connect to the internet or other devices without any physical cables. Electric wires, VGA cables, and USB cables are all types of wired connections. Wireless connections offer flexibility and let devices move around freely.

🎯 Exam Tip: Understand the difference between wired (using cables) and wireless (using radio waves) connections.

 

Question 5. Pen drive is device.
(a) Output
(b) Input
(c) Storage
(d) Connecting cable
Answer: (c) Storage
In simple words: A pen drive is a storage device because it is used to save and carry digital information. It helps you keep your files safe and move them between different computers. Storage devices are crucial for saving all kinds of digital data.

🎯 Exam Tip: Classify devices based on their primary function: input, output, processing, or storage.

II. Match The Following

 

Answer:
1. - Connecting Cable
2. - Wireless connection
3. - Output device
4. - Input device
5. - LDMI
In simple words: We match computer parts and technologies with their correct functions or categories. For example, VGA is a type of cable that connects devices, and Bluetooth is a way to connect wirelessly. Matching exercises help us understand the specific roles of different components.

🎯 Exam Tip: Carefully read each item and its possible matches, connecting them based on their primary function or category.

III. Give Short Answer:

 

Question 1. Name the parts of a computer.
Answer: A computer mainly has three important parts that work together. These parts are:
1. Input unit
2. Central Processing Unit (CPU)
3. Output unit
These parts work in a sequence: Input \( \rightarrow \) CPU \( \rightarrow \) Output. This basic architecture is fundamental to how most modern computers operate.
In simple words: The three main parts of a computer are the Input unit, the Central Processing Unit (CPU), and the Output unit. Each part has a special job.

🎯 Exam Tip: When listing parts, always mention the three main units: Input, Processing, and Output, and show their functional flow.

 

Question 2.
Answer: The table below compares Input and Output units and their devices:

Input devices are how we give information and commands to the computer for it to process. Output devices are how the computer gives us back information in a way we can understand. The interaction between input and output devices allows us to communicate with computers and receive results from their processing.
In simple words: Input devices are for sending data to the computer, like a keyboard. Output devices are for getting information back from the computer, like a monitor.

🎯 Exam Tip: Clearly define the role of input and output, and provide multiple specific examples for each to show comprehensive understanding.

Activity

Look at how to connect cables to a desktop computer using the 4-3-2-1 formula. You start with 4, then go to 3, then 2, and finally 1. Once these steps are complete, your computer will be ready to use.

To assemble a computer, students need to connect its various parts. For this construction activity, the 4-3-2-1 formula is used to guide the connection process.

Samacheer Kalvi 6th Science Parts Of Computer Additional Important Questions And Answers

I. Choose The Correct Answer:

 

Question 1. Which one of the following is not important part of computer?
(a) Input device
(b) Output device
(c) Mouse
(d) Central Processing Unit
Answer: (c) Mouse
In simple words: While a mouse is very useful, a computer can still work without one, for example, by using only the keyboard. Input devices, output devices, and the Central Processing Unit (CPU) are the essential parts a computer needs to function. The core functionality of a computer depends on its ability to process data, not necessarily on a mouse.

🎯 Exam Tip: Understand the difference between essential computer components (like CPU, memory, basic input/output) and peripheral devices (like a mouse, which can be optional).

 

Question 2. The page on the monitor can be moved up and down using the _____
(a) Right button
(b) Scroll ball
(c) Left button
(d) Number key
Answer: (b) Scroll ball
In simple words: You can move a page up and down on the screen using the scroll ball (also called a scroll wheel) on your mouse. This makes it easy to read long documents or web pages. The scroll wheel is an ergonomic feature that improves navigation.

🎯 Exam Tip: Think about the common actions you perform with a mouse and identify which part controls specific movements like scrolling.

 

Question 3. Which one of the following is an example for wireless connection.
(a) USB
(b) power cord
(c) HDMI
(d) wi-fi
Answer: (d) wi-fi
In simple words: Wi-Fi is a type of wireless connection that lets devices connect to the internet or other devices without needing any cables. USB, power cords, and HDMI are all types of wired connections. Wireless technologies offer convenience and greater mobility.

🎯 Exam Tip: Remember that "wireless" means no physical cables are used to transmit data, distinguishing it from options like USB or HDMI.

 

Question 4. The data is measured in units which is called as _____
(a) micron
(b) meter
(c) millimeter
