Q1: What is a computer?

Answer:
A computer is an electronic device that takes input, processes it, and gives output, while also being able to store data for future use.
💻 It's basically a super-efficient, emotionless multitasker 😭

Q2: What are the main components of a computer system?

Answer:

Hardware – The physical parts (CPU, keyboard, monitor, etc.) Software – The programs & applications (like MS Word, Python, etc.) Data – Raw facts & figures Users – Us. The ✨humans✨ giving instructions

Think of it like:
🖥️ + 💿 + 🔢 + 🧍‍♀️ = 💻 Computer System!

Q3: What is the difference between hardware and software?

Hardware

Software

Physical parts

Programs or instructions

Can be touched

Can't be touched

Example: CPU, keyboard

Example: MS Excel, games

✨Analogy: If a computer is a brain—hardware is the brain organ, software is the thoughts.

Q4: What are the types of software?

Answer:

System Software – Runs the computer (e.g., Operating Systems like Windows, Linux) Application Software – For specific tasks (e.g., Canva, Word, Python IDEs) Utility Software – Maintenance tools (e.g., antivirus, disk cleaner)

Q5: What is data and information?

Data = raw facts (like: "Tuli", "16", "Python") Information = meaningful output from processing data (like: "Tuli is 15 and learning Python")

Q6: What are the characteristics of a computer?

Answer:

Speed – Fast like your crush ghosting you 💀 Accuracy – Very low chance of mistakes Automation – Can work non-stop Versatility – Can multitask like a Gen Z queen 👑 Storage – Has more memory than both of us combined 😭

Q7: Define IPO cycle.

Answer:
The IPO cycle is the Input-Process-Output cycle, i.e.:

Input – Giving data (e.g., typing) Process – Working on it (CPU does the magic 🪄) Output – Getting results (screen shows answer)

Q8: What is a CPU?

Answer:
CPU = Central Processing Unit = brain of the computer 🧠💻
It does all the processing.

It has:

ALU (Arithmetic Logic Unit) – Does math and logic CU (Control Unit) – Controls and directs operations

Q9: What are Input and Output devices?

Input Devices – Used to enter data (e.g., keyboard, mouse, scanner) Output Devices – Show result (e.g., monitor, printer, speakers)

Q10: Define memory. What are its types?

Answer:
Memory stores data/instructions.

Primary Memory (Main memory): RAM – Temporary, fast ROM – Permanent, non-editable Secondary Memory: HDD, SSD, pen drive – Big storage but slower

✨ Memory = Your brain notes.
✨ Storage = Your file cabinet.
