Shortcuts and Memory Questions for IBPS RRB CLERK

Keyboard Shortcuts — Windows and General

Windows OS has a set of standard shortcuts that are tested frequently. These shortcuts help perform actions without using the mouse. The exam tends to ask what a specific shortcut does or which shortcut performs a given task.

• Ctrl + C = Copy, Ctrl + X = Cut, Ctrl + V = Paste — the holy trinity
• Ctrl + Z = Undo, Ctrl + Y = Redo — reverse and re-do last action
• Ctrl + A = Select All, Ctrl + S = Save, Ctrl + P = Print
• Alt + F4 = Close current window, Alt + Tab = Switch between open windows
• Windows key + D = Show Desktop, Windows key + E = Open File Explorer
• Ctrl + Alt + Delete = Open Task Manager / security options screen

MS Word Shortcuts

MS Word shortcuts are the most frequently tested in IBPS RRB Clerk. Questions typically ask: which shortcut opens Find and Replace, or which one makes text Bold. Focus on formatting and navigation shortcuts.

• Ctrl + B = Bold, Ctrl + I = Italic, Ctrl + U = Underline — formatting trio
• Ctrl + F = Find, Ctrl + H = Find and Replace, Ctrl + G = Go To
• Ctrl + Home = Go to beginning of document, Ctrl + End = Go to end
• Ctrl + K = Insert Hyperlink, Ctrl + T = Hanging Indent
• F7 = Spelling and Grammar Check, F12 = Save As
• Ctrl + E = Center align, Ctrl + L = Left align, Ctrl + R = Right align, Ctrl + J = Justify

MS Excel Shortcuts

Excel shortcuts focus on navigation and formula-related shortcuts. IBPS RRB Clerk exam tests basic Excel shortcuts — especially those related to functions and cell operations.

• Ctrl + Home = Go to cell A1 (start), Ctrl + End = Go to last used cell
• F2 = Edit active cell, F4 = Repeat last action / toggle absolute reference
• Ctrl + Shift + L = Toggle AutoFilter on/off
• Alt + Enter = New line within same cell
• Ctrl + semicolon (;) = Insert current date, Ctrl + Shift + colon (:) = Insert current time
• Ctrl + 1 = Open Format Cells dialog box

Types of Computer Memory

Memory in computers is classified by speed, capacity, and cost. The memory hierarchy goes from fastest and smallest (registers) to slowest and largest (secondary storage). Understanding this hierarchy helps answer both direct and application-based questions.

• Registers — fastest memory, located inside CPU, stores data currently being processed
• Cache Memory — between CPU and RAM, stores frequently used data, faster than RAM (L1, L2, L3 levels)
• RAM (Random Access Memory) — primary/main memory, volatile (data lost on power off), temporary storage
• ROM (Read Only Memory) — non-volatile, stores BIOS/boot instructions, cannot be easily modified
• Secondary Memory — HDD, SSD, USB, CD/DVD — permanent storage, slowest but highest capacity
• Virtual Memory — portion of hard disk used as RAM when RAM is full — not real RAM

RAM vs ROM — Key Differences

This is a very commonly tested comparison. Exams ask direct questions like: which memory is volatile, which stores BIOS, which is modified during use. Know this table by heart.

• RAM = Volatile (data lost when power off), Read/Write, used by running programs
• ROM = Non-volatile (data retained), Read Only (mostly), stores permanent instructions like BIOS
• Types of RAM: SRAM (Static — used in cache, faster) and DRAM (Dynamic — used as main RAM, slower)
• Types of ROM: PROM (Programmable once), EPROM (Erasable by UV light), EEPROM (Electrically Erasable — like pen drives use Flash which is based on EEPROM)
• Flash Memory is a type of EEPROM — used in pen drives, SSDs, memory cards
• RAM size affects speed of multitasking; ROM size affects system startup

Memory Units and Hierarchy

Memory is measured in bits and bytes. The exam asks conversions and also tests the hierarchy of memory size units. Know the order from smallest to largest.

• 1 Byte = 8 Bits, 1 Kilobyte (KB) = 1024 Bytes, 1 Megabyte (MB) = 1024 KB
• 1 Gigabyte (GB) = 1024 MB, 1 Terabyte (TB) = 1024 GB, 1 Petabyte (PB) = 1024 TB
• Memory speed hierarchy (fastest to slowest): Registers > Cache > RAM > Secondary Storage
• Memory cost hierarchy (most expensive to cheapest): Registers > Cache > RAM > Secondary
• A nibble = 4 bits, A word = depends on system (16-bit, 32-bit, or 64-bit)
• Primary memory = RAM + ROM; Secondary memory = HDD, SSD, Optical Disk

• Confusing Ctrl + H (Find and Replace) with Ctrl + F (Find only) — remember H for sHift/Replace
• Thinking RAM is non-volatile — RAM always loses data on power off, ROM does not
• Confusing Cache memory with ROM — cache is volatile and stores recently used data, not permanent instructions
• Mixing up EPROM (UV light erased) and EEPROM (electrically erased) — exam directly asks this
• Assuming 1 KB = 1000 bytes — in computers it is always 1024 bytes, not 1000

• Shortcut trio: C for Copy, X looks like scissors for Cut, V looks like insertion arrow for Paste — CVX trick
• RAM vs ROM memory aid: RAM = Runs All Memory (temporary, running programs), ROM = Read Only Memory (permanent, boot instructions)
• Memory speed order mnemonic: Really Cool RAM Stores — Registers, Cache, RAM, Secondary — fastest to slowest
• KB MB GB TB PB — King Must Get The Prize — remember the order of memory units

• IBPS RRB Clerk Computer section has 40 questions — shortcuts and memory together can contribute 4 to 6 questions, so this is a high-return topic with zero calculation needed
• MS Word shortcuts are most frequently asked — F7 for spell check and Ctrl + H for Find and Replace appear almost every year
• Memory type questions are usually asked as MCQs with tricky options — for example which among the following is volatile — so know RAM is volatile and ROM is not
• Questions on memory units (KB MB GB conversions) are simple and take less than 20 seconds each — never skip these
• Recent pattern shows Excel shortcuts gaining more importance — especially F2, F4, and Ctrl + semicolon — spend extra 2 minutes reviewing Excel shortcuts
