John has been using a computer for the past 6 months, loading a lot of software and media on the computer. He has never connected his computer to the Internet. For the past few weeks, his computer has been slow to respond to any commands to open a file or copy files. Which of the following options could make his computer faster?
  1. Disk Defragmenter
  2. Antivirus software
  3. Firewall software
  4. Upgrading the processor
Explanation
Answer - A - Use Disk Defragmenter to increase the access speed by rearranging files stored on a disk to occupy contiguous storage locations. To use Disk Defragmenter, you can select it from Start >Programs > Accessories > System Tools or use a software package such as Norton Utilities that has a disk optimization program built into it.

Key Takeaway: Most of the time when a hard drive is full of data, the programs are slow to respond. This is because the data stored on the hard drive is not stored sequentially. Data is divided into smaller chunks and stored at different locations on the hard drive. When a program is required to open, these chunks of data have to be picked up from different parts of the hard drive.

Disk defragmenter assembles data related to a program or software in a sequential manner, thus reducing the access time. This in turn makes the computer respond faster.
