Let’s solve this step by step.
We are given 5 blanks (a to e) and 5 word options:
Byte, Flash, Only, ROM, Volatile
We need to match each blank with the correct word from the options.
---
a. A _______________ is the unit of measuring computer memory.
→ The basic unit for measuring computer memory is a
Byte.
(Think: 1 Byte = 8 bits — it’s how we measure file sizes, RAM, etc.)
✔ So,
a → Byte
---
b. The _______________ drive is small, easy-to-use storage device that can be carried around in your pocket.
→ This describes a
Flash drive (also called USB flash drive).
(It’s portable, plugs into USB ports, and stores data.)
✔ So,
b → Flash
---
c. The _______________ is a non-volatile memory.
→ Non-volatile means it keeps data even when power is off.
ROM (Read-Only Memory) is non-volatile — it holds firmware or boot instructions permanently.
✔ So,
c → ROM
---
d. The memory that loses its contents when the power supply is turned off is called _______________ memory.
→ That’s
Volatile memory.
(RAM is volatile — if you shut down your computer, everything in RAM disappears.)
✔ So,
d → Volatile
---
e. The full form of ROM is Read _______________ Memory.
→ ROM stands for
Read Only Memory.
(The “Only” part means you can’t normally write to it — it’s pre-written by the manufacturer.)
✔ So,
e → Only
---
All words used exactly once: Byte, Flash, ROM, Volatile, Only — perfect!
Final Answer:
a. Byte
b. Flash
c. ROM
d. Volatile
e. Only
