A client application is desktop computer or workstation connected to a network that is capable of obtaining information and applications from a remote server. A program that is capable of obtaining a service provided by another program.
Denial of Service Attacks are a type of attack on a network that is designed to bring the network to its knees by flooding it with useless traffic. Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols.
Quantum key distribution (QKD) uses quantum mechanics to secure a communication channel. It enables two different parties to develop a shared random secret key known only to them, which can then be used to encrypt and decrypt messages.
What makes quantum key distribution unique is its ability to enable the two communicating users to detect unwanted attempts at trying to gain knowledge of the key. This ability is supported by a fundamental aspect of quantum mechanics: the process of measuring a quantum system in general disturbs the system. If an attacker is trying to eavesdrop on the key, the attacker must in some way measure it, thus introducing detectable anomalies.

A computer is Turing complete if it can solve any problem that a Turing machine can, given an appropriate algorithm and the necessary time and memory. When applied to a programming language, this phrase means that it can fully exploit the capabilities of a Turing complete computer.
A hypothetical device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer.
