Ghost imaging, using ghosting software, is a method of converting the contents of a hard drive — including its configuration settings and applications — into an image, and then storing the image on a server or burning it onto a CD.
When contents of the hard drive are needed again, ghosting software converts the image back to original form.
Companies use ghost imaging when they want to create identical configurations and install the same software on numerous machines. For instance, if a company needs to dole out 100 laptops to its employees, then instead of manually setting configurations, and installing applications on each machine, ghosting software (usually contained on a floppy ) will retrieve the ghost image from the server, convert it into its original form, and copy it onto the laptop.
Now the laptop is ready for use.
- ghost site
A Web site that remains live but is no longer updated or maintained or only done so very infrequently. Unlike a site that is no longer available and results in a 404 error message when the user tries to access it, ghost sites can be accessed even though they have not been updated. Web sites […]
When used in reference to networks, a giant is a packet that is too large to traverse the network. Network protocols such as Ethernet often require that packets can not be over a specific number of bytes in order to travel the network.
Short for gigabit Point of Presence, a network access point that supports data transfer rates of at least 1 Gbps. Currently, only a few gigaPOPs exist, and they’re used primarily for accessing the I2 network. Each university that connects to I2 must do so through a gigaPOP, which connects the university’s LANs and WANs to […]
- giga (G)
(1) When decimal notation is used, giga stands for 10 to the 9th power. For example, a gigavolt is 1,000,000,000 volts. (2) When applied to computers, which use the binary notation system, giga represents 2 to the 30th power, which is 1,073,741,824, a little more than 1 billion. A gigabyte, therefore, is about 1.073 billion […]
(1) When used to describe data storage, 1,024 megabits. (2) When used to describe data transfer rates, it refers to 10 to the 9th power (1,000,000,000) bits. Gigabit is abbreviated Gb, as opposed to gigabyte, which is abbreviated GB.
