Is it a bit dramatic, perhaps, to say that the fate of the world rests on computer science and that’s why you should learn computer science? Maybe, but not by much. Computer science is “the study of computation and information, and is a subject which involves you in the very make-up of the world,” the University of York posits. Computer science is everywhere in our everyday lives. I wrote this article on a PC; you’re reading it on one, or a mobile phone.
Sorry it took so long for me to get this one out! Advanced Algorithms was just released, and I’m excited to let you all get your hands on it, even if you’re just auditing it for free! The more advanced material takes quite a bit longer to produce, I wanted to triple check to make sure I got everything correct and that I’ve presented it in a way that makes it easy to understand.
With the influx of interest in the edTech site I’ve been building, I’ve been getting a question that I don’t think I had previously taken the time to really think through, “Is computer science hard?”. Like most things, the answer depends on your perspective and current situation. That said, my guess is that a standard computer science education is easier than most of my readers think. Take as an analogy two friends, one weighs 300 lbs and is trying desperately to lose weight, the other friend weighs 100 lbs and wants to pack some on.
What is a Binary Search Tree? A binary search tree, or BST for short, is a tree whose nodes store a key that is greater than all of their left child nodes and less than all of their right child nodes. Binary trees are useful for storing data in an organized manner so that it can be quickly retrieved, inserted, updated, and deleted. This arrangement of nodes lets each comparison skip about half of the rest of the tree, so the entire search is lightning fast.
A linked list is a linear data structure where elements are not stored next to each other in memory. Unlike and array, elements in a linked list use pointers or references to each other to keep the list intact. Like arrays or traditional lists, linked lists are an ordered collection of objects. Linked lists stand apart from lists in how they store elements in memory. While regular lists like arrays and slices use a contiguous memory block to store references to their data linked lists store references or pointers as part of each element.
The most important thing to understand about these two fields of study is that, ultimately, they are similar. At the end of the day, Software Engineering and Computer Science will both help to make you a better programmer and developer, and the only difference between the two is how they are applied. Software Engineering tends to be more practical, and Computer Science tends to be more theoretical. In a way, Software Engineering is just applied Computer Science, and using that as a starting point, we can examine the differences between the two.
There are so many reasons to want to get a certificate in computer science in 2021, especially when you compare it to alternatives like getting a degree or attending a coding bootcamp. While computer science certificates take time and sometimes money to complete, they still accomplish the same aim as degrees and bootcamps: to show future employers that you have the skills and understanding required to get the programming job of your dreams, and you can get one in a heck of a lot less time and money than a degree.
It’s really hard to get your foot in the door for engineering interviews, especially if you have no experience and are looking for an entry-level position. Often times, more experienced candidates looking to find a higher-paying job can also have trouble. As an employer myself, I can tell you that one of the biggest mistakes I see in 75% of resumes is using a visually boring template. When I’m sifting through forty or fifty applicants, it’s really easy for my eyes to glaze over.
There are many jobs within the software industry, and most of them are easier to land, or are higher-paying once you land them, if you have a solid grasp of computer science fundamentals. You don’t need a degree from an accredited university in 90% of cases, but you do need to learn the material, whether it be online, on the job, or in a formal setting. Let’s explore the most common computer science job titles and their associated compensation, details, and duties.
As technology continues to advance, the need for professionals who are capable of utilizing and understanding computers continues to grow. This demand creates a strong job market, with excellent pay and exclusive opportunities. However, there are two fields of study when it comes to working with this technology: Computer Information Systems and Computer Science. Both are useful areas of study with in-demand skills, but what are the benefits of each, in comparison to each other?
