Router is a device that connects networks and determines the best route data should travel to reach its destination and then sends it along that route. Compare and contrast full and incremental backups. A full backup makes a duplicate of all files selected for backup. An incremental backup duplicates only those files that have changed since the last backup. Incremental backups are faster to perform but are slower to restore.
Differential backups take up more disk space than an incremental backup.
Compare and contrast the two programs. ScanReg and ScanRegW are the programs that make up the Registry Checker. ScanRegW will neither fix nor restore the registry like ScanReg, but ScanRegW will compress a backup. Lastly, ScanRegW runs in protected mode while ScanReg runs in real mode. The safest method of modifying the registry is to use the Control Panel.
