Answer:
D) extents
Explanation:
Disks fragmentations in computer science refers to the cases of a file system laying out its contents in a non-continuous manner thus preventing an in-place alteration of the contents (that is the contents of the file are scattered in fragments across different location on the disk). Disk fragmentation is mostly associated with aging. To mitigate against this, modern implementation of file systems try to preallocate longer chunks of disk space, this is called extents, in this way fragmentation is avoided since a contiguous size of disk space is preallocated to the files and its contents stay together.
B. Add actions
A. a presentation without a clear beginign middle and end
A. add action between slides
Answer: A. passive attacks
Explanation:
Passive attack is a type of attack where by a system is tracked and scanned to determine how vulnerable it is and to also detect open port. The major purpose of a passive attack on a network is to gain access to the information of the target without altering the data.
A passive attack on a network may not be necessarily malicious, it is a type of network attack that is very difficult to detect.
Methods of carrying out passive attacks.
•War driving: scanning of networks is carried out to detect Wi-Fi that are vulnerable.
•Dumpster driving: Attackers or intruders search for information from discarded computers and
other gadgets, those information can help to attack a network.
