There are two main types of encryption - <span>symmetric and asymmetric.
Using symmetric encryption, you use a single secret key that is used to both encrypt and decrypt the data. This form of encryption has been used way before computers! Without this key it is very hard to decrypt a message. However, the issue with this is that if you want to send an encrypted message, you also have to send a key to them, and </span>if your somebody unintended intercepts the
key, they can read the message.
What's the solution? Asymmetric cryptography or public key encryption. Asymmetric cryptography uses encryption that splits the key into two
smaller keys. One of the keys is public and one is kept private.
A good metaphor for understanding this is the public key is the lock, and the private key is the key. You can encrypt a message to send to somebody with their public key, locking it, which they can then decrypt, unlock, with their private key. And vice versa. So with this kind of encryption it's very difficult to decrypt a message for anybody but the owner as it's much harder to steal when it doesn't need to leave their computer, but easy to encrypt messages to send to them
Answer:
1) Execution time speed
2) Responsiveness
3) use of multi-processor architecture
4) sharing of resources
5) use of resources
Explanation:
The Distinct features are
1) Execution time speed : The time of execution in a multithreaded programming is lesser than a Non multithreaded programming which means the execution speed is faster
2) Responsiveness : Multithreaded programming languages are more responsive because every thread in the language is independent of others hence they can respond/generate responses based on its execution
3) Multithreaded programming makes use of multi-processor architecture given that each response from the threads are simultaneous
4) Ease in sharing of resources by the multiple threads found in the programming
5) Light weight of threads makes the need for resources by the threads in the programming language to be lesser when compared to other programming languages
