synchronous vs asynchronous examples
Example 1: synchronous vs asynchronous encryption
Encryption can be synchronous or asynchronous. Synchronous cryptography is mostly used for data at rest, and also for digital signature. Asynchronous cryptography is usually used for data in transit and in cases where encryption and decryption keys need to be shared or exchanged.
Example 2: synchronous vs asynchronous functions javascript
var result = database.query("SELECT * FROM hugetable");
console.log("Query finished");
console.log("Next line");
database.query("SELECT * FROM hugetable", function(result) {
console.log("Query finished");
});
console.log("Next line");
