Exam Prep: Computing Systems and Networks (Big idea 4)

HTTPS

HTTPS

________ should be used for any secure transaction, such as those involving financial data, medical data, and sites that require a password.

Routers

________ are computing devices along a path that send the information along to the next stop on the path.

UDP

________ does not send a confirmation message back to the sender when packets are received.

cables

The Internet is very hardware driven with wires, ________, and devices such as routers and servers.

Data streams

________ are information transmitted via the Internet.

IP

The address is called an Internet Protocol (________) address.

Protocols

________ are a set of rules.

TCP IP

________ stands for: Transmission, Control, Protocol /Internet, Protocol.

multiple paths

It is built in by providing ________ between devices on the Internet.

enable devices

The addresses ________ to find and communicate with each other.

World Wide Web

The ________ (WWW) is an application that runs on the Internet.

TCP

________ creates the packets at the sending location and reassembles them at the receiving one.

Sequential systems

________ can not scale because each step runs after the one ahead of it finishes.

UDP

________ is another common protocol and stands for: User, Datagram, Protocol.

HTTP

________ is a protocol used by the World Wide Web.

UDP

________ is also built on top of IP similar to how TCP works with IP.

TCP/IP stands for

Transmission, Control, Protocol/ Internet, Protocol

UDP is another common protocol and stands for

User, Datagram, Protocol

Computing Systems

is when various types of computing devices, such as desktop or laptop computers, tablets, servers, routers, and/or sensors, plus software, work together for a use such as managing the power grid, traffic signals, a smart home, or a network such as the Internet.

Routers

are computing devices along a path that send the information along to the next stop on the path.

Internet

is a network of networks.

interconnection of computer networks

The word Internet came from

Data streams

are information transmitted via the Internet.

end-to-end architecture

because the processing is done at each end.

host

Every device on a network is called a

Protocols

are a set of rules.

TCP

creates the packets at the sending location and reassembles them at the receiving one.

UDP

is also built on top of IP similar to how TCP works with IP.

Fault-Tolerant

There is a lot of redundancy or duplication built into the Internet on purpose.

World Wide Web (WWW)

is an application that runs on the Internet.

HTTP

is a protocol used by the World Wide Web.

Sequential systems

cannot scale because each step runs after the one ahead of it finishes.

Parallel Computing Systems

can be used to speed up the processing.

Distributed Computing Systems

This model can handle the speed and memory requirements for heavy-duty processing needs that a single computer cannot due to resource constraints.
