The Battle of Britain was an air-to-air combat between the RAF and the Luftwaffe to show who's better in the air or not. The Blitz was the strategic bombing campaign against British cites by the German Luftwaffe bombers. It was likely that around 20,000 Londoners died during the bombings. Views.
The Secure Shell protocol version 2, or SSH2, specifies how a client can connect securely to an SSH server, and then use the resulting secure link to access the server's resources.Among other things, the client can run programs; transfer files; and forward other TCP/IP connections over the secure link.he SSH2 protocol is a descendant of the SSH v1.x series of protocols. SSH version 2 is standardized at IETF, and the vast majority SSH implementations now support SSH version 2.
The SN2 reaction is a type of reaction mechanism that is common in organic chemistry. In this mechanism, one bond is broken and one bond is formed synchronously, i.e., in one step.S N 2 is a kind of nucleophilic substitution reaction mechanism.Since two reacting species are involved in the slow (rate determining) step, this leads to the term s ubstitution n ucleophilic (bi-molecular) or SN2, the other major kind is SN1.his is because the nucleophile attacks from the back of the substrate, thus breaking the carbon-leaving group bond and forming the carbon-nucleophile bond. Therefore, to maximise the rate of the S N 2 reaction, the back of the substrate must be as unhindered as possible.
