You discover a hard drive is not being optimized on an automatic schedule. Before you run the optimize drive tool, why should you first run disk cleanup? How does defragmentation improve performance? When you ran the CHKDSK command in this lab, it had to run during the startup process. Why was this necessary? What form of the Chkdsk command can you us in a command prompt window? Based on what you learned in this lab along with your other experiences with disk cleanup, which type of files removed by disk cleanup took up the most space? What is one type of app that should absolutely begin at startup in order to protect your computer from attack?

Answer

Before running the drive optimize tool, it is necessary to run Disk Cleanup to remove unnecessary files to clean up the disk space.

de-fragmentation improve the performance in terms of speed of the application, software and file running, and also improve the utilization of space in hard disk.

CHKDSK is the command that is used to check the status of hard disk and file system. By running this command we can check the file system and disk status. This command have different parameters to check the status, we can use it as  "chkdsk 'parameters' "   in command prompt.

In disk cleanup hard disk has been scanned for temporary files and deleted files from different drives. In disk cleanup process the these files has been detected and deleted from the system.

Anti-Virus software is start at the absolute beginning of at the startup of the computer to protect the computer from different attacks.

Explanation:

In disk clean up of the disk unnecessary files has been detected and deleted from the system to clear the memory and save more space for needful and purposeful data.

In de-fragmentation, the fragmented files in the hard disks that are stored at different addresses of the hard drive has been arranged, so that the space and addresses between different files has been combined together and the data and files stored in order. This will help to improve the performance of the system in terms of speed.

CHKDSK is the command that is used to check the status of file system and hard drive. This command will run in command prompt along with different parameters that are needed to be checked.

Anti virus software is used to protect the system from the attack of different malware and virus software. It will start at the beginning of the startup of the system for the purpose of protection.
