INSY 2303 STUDY GUIDE 2026 QUESTIONS AND
SOLUTIONS RATED A+
✔✔non-volatile storage - ✔✔Storage which does not lose its contents when the power
is removed, such as ROM and flash drives
✔✔Durability of storage - ✔✔
✔✔Dependability of storage - ✔✔
✔✔capacity of storage - ✔✔
✔✔Serial processing - ✔✔One instruction at a time the processor must complete all
steps in the instruction cycle before it begins to execute the next instruction
✔✔Pipeline processing - ✔✔When a processor begins to execute an instruction before
it completes the previous instruction
✔✔Parallel processing - ✔✔Executes more than one instruction at a time
✔✔Communications Network - ✔✔A collection of devices used to originate, send, route,
and receive data transmissions.
✔✔Communications Channel - ✔✔Any pathway between the sender and receiver.
✔✔Wired vs Wireless - ✔✔Wired channels transport data through wires and cables.
Wireless channels transport data from one device to another without the use of cables
or wires.
✔✔Network Topology - ✔✔The physical structure of a network including its devices and
connections.
✔✔Network Node - ✔✔In a network, a connection point; in a hierarchical database, a
segment or record type.
✔✔Modem - ✔✔A device that modulates and demodulates data over an analog signal
sent via a telephone line.
✔✔TCP/IP - ✔✔(Internet Protocol) one of the main protocols of TCP/IP; responsible for
addressing packets so that they can be routed to their destinations
✔✔IPv4 - ✔✔The Internet Protocol version 4 is the dominant protocol for routing traffic
on the Internet, offers 32 bit addresses
, ✔✔IPv6 - ✔✔The Internet Protocol version 6 provides a large number of new addresses
to route Internet traffic, offers 128 bit addresses
✔✔Private IP address - ✔✔An IP address that cannot be routed over the Internet
✔✔Public IP address - ✔✔IP addresses that can be routed over the Internet
✔✔DNS - ✔✔(Domain name system) a large database of unique IP addresses that
correspond to domain names
✔✔symmetric connection - ✔✔Any connection to the internet in which the upstream
speed is the same as the downstream speed
✔✔Asymmetric Connection - ✔✔A network connection in which the download capacity
is different from (usually faster than) the upload capacity.
✔✔LAN - ✔✔Local Area Networks are often referred to as LANS. They are designed to
provide connectivity for devices within a limited area, typically within the premises of a
home, office, or school
✔✔NIC - ✔✔Network Interface Controller Card, a computer card plugged into a slot on
the motherboard inside of the computer and allows a network cable to be plugged in so
it can interface or communicate with other computers.
✔✔Ethernet - ✔✔A popular network technology in which network nodes are connected
by coaxial cable or twisted-pair wire.
✔✔Communication protocols - ✔✔A set of rules that ensures the orderly and accurate
transmission and reception of data.
✔✔Physcial communication protocols - ✔✔Specific cable and signal standards for the
channels that carry data
✔✔Transport communication protocols - ✔✔Make sure data gets to its destination by
establishing standards for dividing data into chunks, assigning addresses, and
correcting errors
✔✔Arrival communication protocols - ✔✔Convert data into standard formats that can be
used by applications, such as email, web browsers, and Skype
✔✔ARPANET - ✔✔The Advanced Research Projects Agency Network, one of the first
packet switching computer networks using TCP/IP and the prototype for the internet
