Bangladesh Bank Data Entry/Control Operator (IT) Exam 16 October 2026 — Question Solution | বাংলাদেশ ব্যাংক ডাটা এন্ট্রি/কন্ট্রোল অপারেটর (আইটি) নিয়োগ পরীক্ষা ২০২৬ — প্রশ্ন সমাধান

Answer: change the Boot Order (Boot Priority / Boot Sequence) setting so that the SSD's OS boot entry is Boot Option #1, ahead of Network Boot (PXE, "LAN" or "IPv4/IPv6 Network").

Why the PC boots from the network: at power-on the firmware tries the boot devices one by one, in the configured order, and starts the first one that is bootable. The SSD is detected, so the hardware is fine; the problem is that the network (PXE) entry comes before the SSD, or the SSD entry is missing from the boot list, so the firmware loads a network boot program instead.

flowchart LR
    A["Power on and POST"] --> B["Firmware reads the boot order"]
    B --> C{"Option 1: Network PXE"}
    C -- "listed first" --> D["Tries to boot from the network"]
    B --> E["Fix: Option 1 = SSD, Windows Boot Manager"]
    E --> F["OS loads from the SSD"]

Steps to fix:

1. Restart and press the setup key (usually Del, F2 or F10; it differs by manufacturer) to open BIOS/UEFI Setup.
2. Go to the Boot tab → Boot Option Priorities / Boot Sequence.
3. Set Boot Option #1 to the SSD; on a UEFI system the entry is usually named after the OS boot loader, e.g. "Windows Boot Manager (SSD model)".
4. Move Network/PXE boot down, or disable it (often "Network Stack", "PXE Boot" or "LAN Option ROM") if the PC never needs to boot from the network.
5. Press F10 → Save and Exit.

If the SSD still does not appear as a boot option: check the Boot Mode setting. An OS installed in UEFI mode (GPT disk) will not show as bootable when the firmware is set to Legacy/CSM, and vice versa, so the firmware falls through to the network. Set the boot mode to match the way the OS was installed.

Exam tip: "Drive detected but wrong device boots" → Boot Order/Boot Priority; mention disabling PXE and matching UEFI/Legacy mode as supporting fixes.

Answer:

• The RAM upgrade (8 GB → 16 GB) lets the computer run more applications simultaneously.
• The SSD upgrade (256 GB → 512 GB) lets the computer store more data.

Why RAM decides how many applications can run: RAM is the computer's main (primary) memory. Every program that is open, together with the data it is working on, must be loaded into RAM, because the CPU works directly with RAM. It is fast but volatile: its contents are lost when power is switched off. With 8 GB, opening many programs (browser tabs, Word, Excel, a banking application, antivirus) fills the RAM; the operating system then moves parts of memory to the disk (virtual memory/page file), which is far slower, so the PC lags. 16 GB doubles the working space, so more programs stay open smoothly.

Why the SSD decides how much can be stored: the SSD is secondary storage. It is non-volatile: it keeps the operating system, installed software and files (documents, photos, databases) permanently, even with the power off. Doubling it to 512 GB doubles the space for saved data. It does not by itself let more programs run at the same time.

Point	RAM upgrade (8 → 16 GB)	SSD upgrade (256 → 512 GB)
Type	Primary memory	Secondary storage
Volatile?	Yes, cleared at power-off	No, keeps data permanently
Holds	Programs and data currently in use	OS, software and files saved for later
Effect of upgrade	More applications at once, better multitasking	More data stored

Worked check: both upgrades double the capacity (16 ÷ 8 = 2; 512 ÷ 256 = 2), but they double different things: working space versus storage space. (Windows shows a 512 GB SSD as about 476 GB, because the drive maker counts 1 GB = 10⁹ bytes while Windows divides by 2³⁰: 512 × 10⁹ ÷ 2³⁰ ≈ 476.8.)

Exam tip: RAM = "how much can be open at once"; SSD/HDD = "how much can be saved".
