A network disaster recovery plan is a procedure designed to prepare an organization to respond to an interruption of network services -- such as Internet access, wide or local area network operation and wireless networking functionality -- during a natural or manmade disaster.
A key risk indicator (KRI) is a metric for measuring the likelihood that the combined probability of an event and its consequence will exceed the organization's risk appetite and have a profoundly negative impact on an organization's ability to be successful.
Cryptography is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. The term is most often associated with scrambling plaintext (ordinary text, sometimes referred to as cleartext) into ciphertext (a process called encryption), then back again (known as decryption).
Continuous software development is a blanket term that covers several aspects of an iterative application development process based on making each change when it is ready, rather than wrapping many changes into large batches.
Definition: Learn what the Open Systems Interconnection (OSI) reference model is and how its seven layers of functions provide vendors and developers with a common language for discussing how messages should be transmitted between any two points in a telecommunication network.
The Internet, sometimes called simply "the Net," is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers).
A domain name locates an organization or other entity on the Internet. For example, the domain name "www.totalbaseball.com" locates an Internet address for "totalbaseball.com" at Internet point 220.127.116.11 and a particular host server named "www."
A static IP address is a number (in the form of a dotted quad) that is assigned to a computer by an Internet service provider (ISP) to be its permanent address on the Internet. Computers use IP addresses to locate and talk to each other on the Internet, much the same way people use phone numbers to locate and talk to one another on the telephone. When you want to visit whatis.com, your computer asks a domain name system (DNS) server (think telephone information operator) for the correct dotted quad number (think phone number) for whatis.com and your computer uses the answer it receives to connect to the whatis.com server.
Definition: Learn what MPLS (Multiprotocol Label Switching) is and why allowing packets to be forwarded at the Layer 2 (switching) level rather than at the Layer 3 (routing) level is important for Quality of Service (QoS).
