QUESTIONS AND VERIFIED ANSWERS /GET IT
100% ACCURATE|ALREADY GRADED A+
Processor - ✔✔ANSWER✔✔>>integrated circuit is a super-thin slice of
semiconducting material packed with microscopic circuit elements, such as
wires, transistors, capacitors, logic gates, and resistors. Usually these circuits
are found in microprocessors.
ALU (Arithmetic Logic Unit) - ✔✔ANSWER✔✔>>performs arithmetic operations,
such as addition and subtraction, as well as logical operations, such as
comparing two numbers to see if they are the same
Logical Storage Model - ✔✔ANSWER✔✔>>Any visual or conceptual aid that
helps a computer user visualize a file storage system. Basically this model is
how we perceive files are saved. The Tree view model is a storage metaphor to
represent the logical storage model. To visualize the model, imagine the director
of a disk as a tree on its side. The trunk corresponds to the root director, the
branches to folders, and the leaves to files.
Physical Storage Model - ✔✔ANSWER✔✔>>A representation of data as it is
physically stored. Basically, this model is how files are actually saved.
File management utility - ✔✔ANSWER✔✔>>software, such as windows explorer,
that helps users locate, rename, move, copy, and delete files.
full - ✔✔ANSWER✔✔>>type of backup; copy of all the files fore a specifed
backup job
, differential - ✔✔ANSWER✔✔>>type of backup; a copy of all the files that
changed since the last full backup of a disk
incremental - ✔✔ANSWER✔✔>>type of backup; a backup that contains files that
changed since the last backup
Formatting - ✔✔ANSWER✔✔>>the processing of dividing a disk into sectors so
that it can be used to store information. Formatting is intergral to completely
deleting data.
Deleting Files (The Process) - ✔✔ANSWER✔✔>>When selecting the delete
option from a files icon, the operating system simply changes the status of the
file's clusters to "empty" and removes the file name from the index file. The file
name no longer appears in a directory listing, but the file's data remains in the
clusters until a new file is stored there. TO delete data in such a way that no one
cna ever read it, you can use special file shredder software that overwrites
supposedly empty sectors with random 1s and 0s.
LAN (Local Area Network) - ✔✔ANSWER✔✔>>An interconnected group of
computers and peripherals located within a relatively limited area, such as
building or campus.
WAN (Wide Area Network) - ✔✔ANSWER✔✔>>An interconnect group of
computers and peripherals that covers a large geographical area, such as
multiple branches of a corporation
Network Devices (Network Appliances) - ✔✔ANSWER✔✔>>Any electronic
devices that broadcast network data, boost signals, or routes datat to its
destination. Examples includ hubs, siwtches routers, gateways, bridges, and
repeaters
Ring - ✔✔ANSWER✔✔>>type of topology; a network in which all devices are
connected in a circle with each device having exactly two neighbors
P2P - ✔✔ANSWER✔✔>>type of topology; a method of using a network in which
workstations act as both file servers and clients
High Bandwidth (Broadband) - ✔✔ANSWER✔✔>>refers to communiactions
channels, such as cable TV and DSL, which have high bandwith
Narrow Bandwidth (Narrowband) - ✔✔ANSWER✔✔>>Refers to communcation
channels, such as dial-up Internet access, which have low bandwidth.
