It is an address for accessing specific web data located on a server (a computer hosting data for others to access).
the standard for communication between browsers and servers (usually "http" or "https")
2. is set of rules to standardize communication
the name of the server that hosts the data.
the location of the data in a hierarchy of folders on the server
is a small chunk of any kind of data: text, numbers, lists, etc
(Internet Protocol) an addressing system that finds paths to distant computers and splits data into small packets sent separately
Transmission Control Protocol), a reliable system of transmitting data packets
There are multiple pathways among the physical connections of the Internet to create redundancy. Even if one pathway is unavailable, there is still another way to transmit a message from sender to receiver (as shown right).
There are two hierarchical Internet addressing systems, domain names (as shown below) and IP addresses. These address hierarchies work much like the postal system, which locates people first by state, then city, then street, then house number, then apartment, and then finally person.
A bit is the smallest unit of data, which can only have one of two values (such as a 1 or 0).
The bit rate of a connection is the numbers of bits of data that can sent in a second.
Bandwidth is the transmission capacity of a system (for digital data, it is measured by bit rate). Higher bandwidth is better; the data will travel more quickly.
Latency is time between the transmission and the receipt of a message. Lower latency is better; the data will take less time to start transmitting.
Storing data in the cloud
Storing data in the cloud means storing it somewhere on the Internet, but you don't know where. The cloud service provider (Google Drive, Dropbox, Snap!, etc.) manages the actual storage location.
A redundant system is one that has back-up elements in case one part fails.
Fault tolerance is the ability of a system to work around problems.
Scalability is the ability of the Internet to keep working as it grows.
