is a physical artifact that can run a program.

is a computing device, but not all computing devices are computers.

is a group of computing devices and programs working together for a common purpose.

is a group of interconnected computing devices capable of sending or receiving data

of a computer network is the maximum amount of data that can be sent in a fixed amount of time.

between two computing devices on a computer network (a sender and receiver) is a sequence of directly connected computing devices that begins at the sender and ends at the receiver.

is the process of finding a path from sender to receiver.

is responsible for addressing and routing your online requests.

is a protocol that defines how computers send packets of data to each other.

Data traveling in the internet is broken down into small chunks of data called

is a protocol that allows computer applications to send messages without checking for missing packets to save on time needed to retransmit missing packets.

When a system can support failures and continue to function

refers to the hardware.

refers to the software used on the internet.

is a computational model in which operations are performed in order one at a time.

takes as long as the sum of all of the steps.

takes at least as long as the longest branch in the program.

is broken into discrete instructions.

takes as long as the longest of the tasks done in parallel.

is needed for real-world simulations and modeling.

allows problems to be solved that could not be solved on a single computer because of either the processing time or storage needs involved.
