Understand the units of digital memory size.
The standard memory size units increase in powers of 1024 (or approximately 1000 for simplified usage):
1 \text{ KB} = 1024 \text{ Bytes}
1 \text{ MB} = 1024 \text{ KB}
1 \text{ GB} = 1024 \text{ MB}
1 \text{ TB} = 1024 \text{ GB}
Step 2: Compare the sizes.
Among the given options:
- KB<MB<GB<TB
Hence, TB (terabyte) is the largest memory size listed.
