  • You may have heard the term Algorithm recently,

  • whether it was online or maybe in some conversation about technology.

  • It's a word that gets thrown around a lot. But what exactly does it mean?

  • Well, simply put an algorithm is a set of steps used to complete a specific task.

  • They're the building blocks for programming

  • and they allow things like computers, smartphones, and websites to function and make decisions.

  • But in addition to being used by technology, a lot of things we do on a daily basis

  • are also similar to algorithms

  • Let's say you want to make some spaghetti.

  • In order to do this successfully, there's a certain set of steps

  • you need to follow in a particular order.

  • First you need to boil a pot of water.

  • Once it's boiling you then add the spaghetti and cook it for a set amount of time, stirring occasionally.

  • Once it's finished you drain the water and then it's ready to be served with a sauce of your choice.

  • That entire process is actually an algorithm. Because you followed those steps in that order,

  • you reached your desired outcome, a delicious pasta dish.

  • But, if you were to make a mistake, say over or under cooking your noodles,

  • it probably wouldn't be as good.

  • Programs work in a similar way. Their code is made up of algorithms telling them what to do.

  • Let's say that we want to use a navigation app to get directions.

  • When we punch in a destination, the app uses an algorithm to look at the various available routes.

  • Next, it uses a different algorithm to check the current traffic. And then a third one takes that information

  • and calculates the best available route.

  • All of these algorithms are built right into the apps code.

  • If there were any kind of error in that code, the app wouldn't be able to follow these algorithms correctly.

  • Meaning, you wouldn't receive your directions.

  • Both of these examples show how both humans and computers

  • can use algorithms to perform everyday tasks.

  • The difference is that computers can use algorithms

  • and calculate things better, faster, and more efficiently than we can.

  • Technology is only going to continue to evolve and get even better at what it does.

  • As long as coding and programming continue to be used,

  • algorithms will be at the heart of these technologies guiding what they do and how they do it.

  • GCF global creating opportunities for a better life.
