IBPS RRB GBO Computer Analysis 2025 | RRB Scale 2 Computer Exam Analysis | IBPS RRB SO Computer |

Summary

Sachin Arora reviews the computer section of the IBPS RRB Scale 2 GBO exam held on 28 December 2025. He says the paper covered a wide range of computer topics and that many candidates reported strong scores—often above 30 or 35 out of 40, with some claiming full marks. He discusses recalled questions and explains the related concepts.

Questions and concepts reviewed

MS Office shortcuts

• Ctrl + H: Find and Replace in Word, Excel, and PowerPoint.
• Ctrl + F: Find.
• F1: Open Help in MS Word.
• Other function keys mentioned:
  • F2: Rename a file or folder.
  • F3: Search.
  • F4: Repeat the last action.
  • F5: Refresh.
• Ctrl + W: Close the current document or tab.
• Alt + F4: Close the active window or exit the application.
• In Excel, bar, pie, and line charts can be inserted from the Insert tab.
• Older Word documents use .doc; newer ones use .docx.

Networking and internet protocols

• IPv4 uses 32 bits; IPv6 uses 128 bits and is represented in hexadecimal. The instructor identifies IPv6 as the newer Internet Protocol version.
• POP3 uses port 110 and is used to receive email. The instructor contrasts it with IMAP, which allows access to email from different devices.
• A VPN is described as a secure connection that carries data through a tunnel. PPTP is mentioned as a tunneling protocol.
• A network serving a room, home, office, or building is a LAN.
• In a mesh topology, each node connects to every other node. The instructor also notes that it uses many wires. A combination of different topologies is called a hybrid topology.
• Network topology refers to how computers are connected in a network.

Computer systems, memory, and generations

• Linux and Unix are identified as operating systems. The instructor says a computer needs an operating system to boot, along with drivers.
• A notebook or laptop is a portable computer and falls under the broader category of microcomputers.
• RAM is volatile (temporary) memory, while ROM is non-volatile. Therefore, for a question asking which memory is “not non-volatile,” the answer is RAM.
• Registers are described as the fastest memory inside the CPU.
• Cache is presented as the memory closest to the CPU. If cache is not among the options, RAM or primary memory may be the intended answer.
• Instructions stored in ROM are referred to as firmware. More precisely, firmware is software stored in non-volatile memory.
• The generations of computers were reviewed as:
  1. First generation — vacuum tubes
  2. Second generation — transistors
  3. Third generation — integrated circuits
  4. Fourth generation — microprocessors
  5. Fifth generation — artificial intelligence, robotics, or knowledge-based systems
• The instructor identifies ENIAC as first-generation and Cray as fourth-generation.

Printers, malware, and other technologies

• A monochrome inkjet printer uses a single black ink cartridge.
• A Trojan horse is malware that disguises itself as useful or legitimate software. The instructor distinguishes it from a virus or worm, noting that it does not replicate in the same way.
• A time-bomb virus is described as malware that activates at a specified date or time.
• Zoom is identified as an online meeting platform.
• Blockchain is identified as the technology used by cryptocurrencies such as Bitcoin.
• Laser technology is mentioned in connection with CDs, DVDs, and laser printers.
• ASCII stands for American Standard Code for Information Interchange.

Overall exam coverage

The instructor says the questions spanned hardware, software, operating systems, memory, networking, malware, number systems, databases, and newer technologies. He also mentions questions involving the OSI model, networking devices, RDBMS, MS Word, Excel, PowerPoint, and number conversion, including binary-to-decimal conversion. He describes the paper as broad in coverage, with some familiar or repeated question types.

He closes by asking viewers to share their computer-section and overall scores, and briefly promotes a computer course offered through the Arora Educator app.
