CUET PG 2022 — Computer PYQ

CUET PG | Computer | 2022

Which of the following storage hardwares can be used as a back-up device?

(A) HDD (B) ROM (C) RAM

(D) Cache (E) Magnetic Tape

Choose the correct answer from the options given below:

Choose the correct answer:

Explanation

Solution Logic

Backup devices ke liye do shartein (conditions) honi zaroori hain:

Non-volatile Memory: Computer band hone ke baad bhi data delete nahi hona chahiye.
High Capacity: Inme zyada matra mein data store karne ki kshamata honi chahiye.

Aaiye har option ko test karte hain:

HDD (Hard Disk Drive): Yeh magnetic storage hai. Isme $1 \text{ TB}$ se $20 \text{ TB}$ tak data save kiya ja sakta hai aur power jane par data safe rehta hai.

$\text{Status} = \text{Non-volatile} + \text{High Capacity} \rightarrow \text{Suitable}$
ROM (Read Only Memory): Isme sirf system ki startup files hoti hain. User isme apna backup nahi rakh sakta.

$\text{Status} = \text{Permanent but Restricted Access} \rightarrow \text{Not Suitable}$
RAM aur Cache: Yeh dono "Volatile" hain. Inka data temporary hota hai.

$\text{Power Off} \rightarrow \text{Data} = 0$

$\text{RAM/Cache} \neq \text{Backup}$
Magnetic Tape: Yeh sabse purana aur bharosemand backup medium hai. Aaj bhi bade data centers iska use karte hain kyunki yeh sasta aur durable hota hai.

$\text{Status} = \text{Sequential Access} + \text{High Durability} \rightarrow \text{Suitable}$

Final Answer

Upar diye gaye solution ke mutabik:

(A) HDD aur (E) Magnetic Tape sahi hain.
(B), (C), aur (D) backup ke liye istemal nahi hote.

Correct Answer: Options mein se jahan (A) aur (E) diya ho, wahi sahi chunav hai.
