Ahmed's 1-terabyte hard drive contains 1024 gigabytes of storage space.
Step-by-step explanation:
Ahmed's new laptop has a 1-terabyte (TB) hard drive which has 1024 gigabytes (GB). In computing, storage space is measured in hierarchical units where one GB contains 1024 megabytes (MB) and one MB is equivalent to 1024 kilobytes (KB). Thus, Ahmed's laptop with a 1 TB hard drive can be said to have approximately 1024 GB of storage space.
