To create copies of files on another storage medium
What is the main purpose of disk compression and file compression?
To reduce file size by removing redundant data in files
What action should virus checkers take if a file or program is suspected to be infected?
Put the file or program in quarantine for further inspection
What does damaged files with bad sectors contain after being repaired?
'Empty' sectors
What is the purpose of disk contents analysis/disk repair software?
To optimize storage by deleting unnecessary files
What is the result of fragmentation on disk access and computer performance?
It slows down disk access and reduces computer performance
What does antivirus software do if a virus is not yet in its database?
Perform heuristic checking for types of behavior that could indicate a virus
Study Notes
Disk Formatting and Management
- A hard disk formatter organizes storage space by dividing the disk into tracks, sectors, and clusters, and creates a file system to manage files and data.
- Full formatting using NTFS deletes all existing data on the disk, and reinitializes the disk for new use.
- Initializing a new hard disk drive prepares it for use by creating a file system and allocating space for data storage.
Data Recovery and Repair
- Reformatting a previously used HDD can make it difficult or impossible to recover existing data, as the old file system is overwritten.
- Disk formatters' checking tools identify and repair bad sectors on a disk, which can contain corrupted or damaged files.
- Repaired files with bad sectors are moved to a new location on the disk, and the bad sectors are marked as unavailable for use.
- Disk contents analysis/disk repair software diagnose and fix disk problems, such as bad sectors, corrupted files, and file system errors.
File Compression and Backup
- File compression software reduces the size of files, making them easier to store and transfer, while maintaining their original content.
- The primary function of backup software is to create a copy of important files and data, to prevent loss in case of disk failure or data corruption.
- Disk compression and file compression both aim to reduce the amount of storage space required for data, but operate on different levels (disk-level and file-level).
Virus Protection and Antivirus Software
- If a file or program is suspected to be infected, virus checkers should quarantine or delete it to prevent the spread of malware.
- Antivirus software uses its database to identify and remove known viruses, and may update its database to include new viruses.
- If a virus is not yet in its database, antivirus software may still detect and remove it using heuristic analysis or other methods.
Fragmentation and Defragmentation
- Fragmentation occurs when files are broken into smaller pieces and scattered across the disk, leading to slower disk access and computer performance.
- Defragmentation software reorganizes files on the disk, grouping together fragmented pieces, to improve disk access and computer performance.
- The result of fragmentation on disk access and computer performance is slower data retrieval and decreased system efficiency.
Test your knowledge about the need for utility software provided with an operating system, which includes tasks like optimizing, maintaining, and managing computer resources. This quiz covers topics such as hard disk formatting, virus checking, defragmentation, disk analysis/repair, file compression, and backup software.
