Many of the programming languages can be split by their use to front-end and back-end programming languages. Back-end programming is usually not visible by others, where front-end programming is. An example of front-end programming is writing a JavaScript code. It is easily accessible by everyone. Example of back-end programming is to create a script that will perform data transformation. Both front-end development and back-end development are important for reliable computerized operations.

Using a programming language to turn an algorithm to a code that a computer can understand is called programming. There are different types of programming languages, I will not be covering these in this article. A different article is dedicated to programming languages, or you can do your own research.

A computer algorithm outlines the steps needed for a computer program to accomplish. It is a good idea to think about steps that a program will do before writing any code. Algorithms can be efficient and not efficient. An example of not efficient algorithm is to perform all of the cycles in a loop to find out which value satisfies a condition, efficient algorithm will exit that loop execution after that value is found.

​Replacing laptop’s keyboard is a delicate task, because a keyboard is connected to laptop’s internal base using a flexible wide cable. Damaging that cable may cause inoperability of that laptop’s keyboard. Attention and care needs to be paid when dealing with that cable.

​Computer screws comes at different sizes. When working with a computer please make sure that screws that were used to tie specific equipment goes back to their previous spots. Screws may have same diameter and tread, so they will physically fit the place of being screwed in, however screws may have different length. Longer screws may cause damage to computer components, shorter screws will not provide same level of tightnesses as longer screws.

​When you are working with computer equipment please make sure that a computer is not just turned off, but completely disconnected from electrical power. This will ensure electrical safety of a person who is working with computer components.
