Which of the following statements is NOT true?a)Hard disk is fixed in ...
Statement A:
- Hard disk is fixed in the computer.
Statement B:
- Storage capacity of a hard disk varies between 1 GB to 60 GB.
Statement C:
- Hard disk consists of platters.
Statement D:
- Each platter requires a read/write head.
Explanation:
Based on the given statements, we need to identify the statement that is NOT true. Let's analyze each statement:
- Statement A: Hard disk is indeed fixed in the computer, so this statement is true.
- Statement B: The storage capacity of a hard disk can vary between different models, but it is not limited to just 1 GB to 60 GB. Hard disks can have much larger capacities, ranging from a few hundred GBs to several TBs. Therefore, this statement is not true.
- Statement C: Hard disks consist of one or more platters, which is true.
- Statement D: Each platter in a hard disk requires a read/write head to access and modify data, which is also true.
Therefore, the statement that is NOT true is B: Storage capacity of a hard disk varies between 1 GB to 60 GB.
Which of the following statements is NOT true?a)Hard disk is fixed in ...
Explanation:
Hard Disk Components:
- A hard disk is a fixed storage device in a computer that is used to store data.
- It consists of one or more circular platters coated with a magnetic material.
Storage Capacity:
- The storage capacity of a hard disk can vary greatly, typically ranging from 1 GB to 60 GB or more depending on the type and size of the hard disk.
Platters and Read/Write Heads:
- Each platter in a hard disk requires a read/write head to access and store data on the magnetic surface of the platter.
- The read/write head moves across the platter to read and write data as needed.
- Multiple platters and read/write heads are stacked on top of each other in a hard disk to increase storage capacity.
Conclusion:
The statement "Each platter requires a read/write head" is true because the read/write head is essential for accessing and storing data on the platters.
