7 concepts every programmer should know

7 concepts every programmer should know

1. Caching

A cache is a hardware or software component that stores data so that future requests for that data can be served faster.

No modern web system runs without a cache.

2. Cloud Computing

It's the on-demand availability of computer system resources, especially data storage and computing power, without a direct active management by people.

Cloud computing is changing the way we deliver large-scale web apps.

3. Concurrency

It's the ability of different parts or units of a program algorithm, or problem to be executed out-of-order or in partial order, without affecting the final outcome.

Concurrency means multiple computations are happening at the same time.

4. Conventions and Templates

Having a good system for naming, code structure, architecture, and processes is critical in delivering quickly and consistently, at scale.

5. Hashing

Hashing is the transformation of a string of characters into a usually shorter fixed-length value or key that represents the original string.

The idea here is for fast access to data.

6. Interface

Any program that's used needs to have a simple and easy interface for people to interact with

7. Time Complexity

Time complexity is the computational complexity that describes the amount of time it takes to run an algorithm.
