TCS Exam
Aliya has 2600 MB of data. Dinesh has 4000 MB of data. The combined data would fit on a USB flash drive of ___________ storage capacity.
Answer (Detailed Solution Below)View answer ▾Hide ▴
Answer: Option D — 10 GB
Detailed Solution
Total data: MB.
In gigabytes, GB (or 6.6 GB in decimal units).
Only a 10 GB drive is large enough.
✓ Check
A 6 GB drive holds at most MB, which is less than 6600 MB.⚠ Common trap
Option C (6 GB) comes from adding only the thousands, 2 GB + 4 GB, and ignoring the extra 600 MB.Quick tip
, so the smallest drive that fits is 10 GB

Computer Memory & Memory Organization — Preparation
This question tests your understanding of Computer Memory & Memory Organization, a key topic in the Computer Awareness section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.
Computer memory stores data and instructions. This topic covers the memory hierarchy, from registers and cache memory to main memory (RAM and ROM) and secondary storage (hard disks, SSDs, optical discs and flash drives). It also covers types of RAM (SRAM and DRAM), types of ROM (PROM, EPROM and EEPROM), virtual memory, and units of memory from bits and bytes to kilobytes, megabytes, gigabytes and terabytes. Exam questions test the differences between volatile and non-volatile memory, which memory is fastest or largest, memory unit conversions, and the role of cache memory. Remember that moving up the memory hierarchy makes memory faster and costlier per bit but smaller in capacity. RAM is volatile and loses its contents when power is switched off, while ROM keeps its contents. Practise the computer memory questions below. Each answer comes with a short explanation.
