Why are SSC GD Computer Science Notes Important?

Are you preparing for the SSC GD Constable exam? You might be focusing on Math, Reasoning, and Hindi. But did you know that in the General Knowledge (GK) section, the SSC often asks basic computer questions?

Many students ignore these questions. They think, “It is just 1 or 2 marks, leave it.” But friends, in a competitive exam, every single mark counts. One mark can decide if you get the BSF or CISF post!

These SSC GD Computer Science Notes are not difficult. You don’t need to be a computer engineer. You just need to know the basics. We have written these notes in such simple language (Class 6th level) that even if you have never used a computer, you will understand everything.

SSC GD Computer Syllabus (Under General Knowledge)

Computer Science is not a separate subject in SSC GD like Reasoning or Math. It is a part of the General Awareness section. Based on previous year papers (2024, 2025), here are the important topics covered in our SSC GD Computer Science Notes:

1. Computer Basics (Hardware & Software)
2. Computer Memory (RAM & ROM)
3. Input and Output Devices
4. MS Office (Word, Excel, PowerPoint) – Most Important
5. Internet and Email
6. Important Full Forms
7. Keyboard Shortcuts

Part 1: Computer Basics (The Brain of the Machine)

Let’s start our SSC GD Computer Science Notes with the basics.

What is a Computer?

A computer is an electronic machine. It takes data from us (Input), processes it (Thinking), and gives us the result (Output).

CPU (Central Processing Unit)

• Simple Definition: The CPU is the Brain of the computer.
• Just like you think with your head, the computer thinks with the CPU.
• Exam Question: Who is the brain of the computer? -> Answer: CPU.

Hardware vs Software

Many students get confused here. Let’s make it simple.

• Hardware: Parts of the computer you can touch.
  • Examples: Monitor, Mouse, Keyboard, Printer, Hard Disk.
• Software: Parts of the computer you cannot touch. These are programs inside the screen.
  • Examples: MS Word, Windows, Google Chrome, Games (PubG).

Part 2: Input and Output Devices

This is a very common question in the SSC GD exam. You must know which device is Input and which is Output.

1. Input Devices (Giving Orders)

These devices help you “talk” to the computer or give orders.

• Keyboard: You type letters (giving data).
• Mouse: You click on things (giving orders).
• Scanner: You put a photo inside, and it goes into the computer.
• Microphone (Mic): You speak, and your voice goes inside.

2. Output Devices (Getting Results)

These devices show you the result of your work.

• Monitor (Screen): Shows you the movie or text.
• Printer: Gives you paper (Hard copy).
• Speaker: Gives you sound.

Trick to Remember: If information goes IN, it is Input. If information comes OUT, it is Output.

Part 3: Computer Memory (RAM & ROM)

In our SSC GD Computer Science Notes, this is a star topic.

1. RAM (Random Access Memory)

• Nature: It is Temporary (Volatile).
• Analogy: Think of RAM like a “Blackboard”. You can write on it, but when the teacher leaves (computer turns off), everything is erased.
• Use: It helps the computer run fast.

2. ROM (Read Only Memory)

• Nature: It is Permanent (Non-Volatile).
• Analogy: Think of ROM like a “Printed Book”. Even if you close the book, the words stay there. They cannot be erased easily.
• Use: It stores the startup instructions.

Part 4: MS Office (Word, Excel, PowerPoint)

This is the most important part of the SSC GD Computer Science Notes. SSC loves to ask questions about MS Word and Excel.

1. MS Word

• Use: It is used for writing documents, letters, and notes.
• File Extension: .docx
• Exam Question: Which software is used to type a letter? -> Answer: MS Word.

2. MS Excel

• Use: It is used for calculations, making tables, and mark sheets. It has rows and columns.
• File Extension: .xlsx
• Exam Question: Where do you find “Rows and Columns”? -> Answer: Spreadsheet or MS Excel.

3. MS PowerPoint

• Use: It is used for presentations (Slideshows).
• File Extension: .pptx

Part 5: Important Keyboard Shortcuts (Must Memorize)

You cannot complete your SSC GD Computer Science Notes without this table. Memorize these!

Shortcut Key	Function (What it does)
Ctrl + C	Copy (Duplicate)
Ctrl + V	Paste (Put it down)
Ctrl + X	Cut (Move)
Ctrl + A	Select All (Everything)
Ctrl + Z	Undo (Go back one step)
Ctrl + S	Save the file
Ctrl + P	Print the file
Alt + F4	Close the program
F5	Refresh (or Start Slideshow)

Part 6: Important Full Forms (Exam Favorites)

In the General Knowledge section, SSC often asks “What is the full form of URL?”. Here is a list for your SSC GD Computer Science Notes.

1. CPU: Central Processing Unit
2. RAM: Random Access Memory
3. ROM: Read Only Memory
4. WWW: World Wide Web
5. HTML: Hyper Text Markup Language
6. HTTP: Hyper Text Transfer Protocol
7. URL: Uniform Resource Locator
8. USB: Universal Serial Bus
9. PDF: Portable Document Format
10. Wi-Fi: Wireless Fidelity
11. LAN: Local Area Network
12. WAN: Wide Area Network
13. Email: Electronic Mail

Part 7: Internet and Email Basics

The internet is a network of networks.

Important Internet Terms:

• Browser: The app you use to open the internet. (Example: Google Chrome, Mozilla Firefox).
• Search Engine: The website where you search for things. (Example: Google, Bing).
• Virus: A bad program that damages your computer.
• Antivirus: A good program that kills the virus. (Example: QuickHeal, Norton).

Email Basics:

• To send an email, you need an Email ID (like student@gmail.com).
• “@” Symbol: Every email must have this symbol.
• Spam: Junk or fake emails are called Spam.
