MGT 3061 Lecture Notes - Lecture 3: Uninterruptible Power Supply, Natural Disaster, Private Network
Document Summary
Combination of hardware and software for improved reliability. Uninterruptible power supply (ups) and redundant array of independent disks (raid) Some threats can be controlled completely or partially, but some cant be controlled. In 2008, the # of computer viruses in existence exceeded one million. Consists of self propagating program code that"s triggered by a specified time or event. Indications of a computer infected by a virus. Programs increasing in size, files have been corrupted or cant be opened, hard disk space is reduced, keyboard locks up or the screen freezes, available memory reduced, disk access is slow. Travels from computer to computer in a network (does not erase data) Independent programs that can be spread themselves without having to be attached to a host program. Replicates into a full blown version that eats up computing resources. Named after the trojan horse that greeks used to enter troy during the trojan wars.
