Chapter 5: System Software
- Anti-virus utilities scan for computer viruses.
- Backup utilities can make a copy of all information stored on a disk, and restore either the entire disk (e.g. in an event of disk failure) or selected files (e.g. in an event of accidental deletion).
- Data compression utilities output a shorter stream or a smaller file when provided with a stream or file.
- Disk checkers can scan the contents of a hard disk to find files or areas that are corrupted in some way, or were not correctly saved, and eliminate them for a more efficiently operating hard drive.
- Disk cleaners can find files that are unnecessary to computer operation, or take up considerable amounts of space. Disk cleaner helps the user to decide what to delete when their hard disk is full.
- Disk compression utilities can transparently compress/uncompress the contents of a disk, increasing the capacity of the disk.
- Disk defragmenters can detect computer files whose contents are broken across several locations on the hard disk, and move the fragments to one location to increase efficiency.
- Disk partitions can divide an individual drive into multiple logical drives, each with its own file system which can be mounted by the operating system and treated as an individual drive.
- Disk space analyzers

Screen/Lcd Laptop Rosak (Putih)
Entri nie khas untuk sesiapa yg ada masalah screen laptop jd putih...
Masalah nie jd kepada diri sy sendiri, model laptop: Acer Aspire 4710
Screen tu jd putih lepas sy install windows vista dulu. Bila sy gerakkan screen tu, dia akan berubah putih. Tapi dia boleh kembali normal lepas sy restart..
Laptop saya jadi macam tu tak sampai setahun pun dari tarikh saya beli. Selama 3 tahun laptop sy macam tu... sy tidak hantar kedai sebab kedai minta RM500 nak betulkan.. (tak mampu huhuhu)
Akhirnya setelah 4 tahun... screen saya putih buat selama-lamanya... (sedih)
Apa nak buat ?
Saya terpaksa guna monitor untuk memaparkan screen tu...
Itu adalah sebahagian cara kalau anda tidak mahu keluar duit RM500...
