Pbs Learning Media: Crash Course Computer Science: The First Programming Languages

Today, we're going to take our first baby steps from hardware into software! Using that CPU we built last episode, we're going to run some instructions and walk you through how a program operates on the machine level. We'll show you how...

Today we're going to take a step back from programming and discuss the person who formulated many of the theoretical concepts that underlie modern computation - the father of computer science himself: Alan Turing. Normally, we try to...

Today we're going to talk about how we organize the data we use on our devices. You might remember last episode we walked through some sorting algorithms, but skipped over how the information actually got there in the first place! And it...

As computers play an increasing role in our daily lives there has been a growing demand for voice user interfaces, but speech is also terribly complicated. Vocabularies are diverse, sentence structures can often dictate the meaning of...

Today, we're going to build the ticking heart of every computer - the Central Processing Unit or CPU. The CPU's job is to execute the programs we know and love - you know, like GTA V, Slack... and Power Point. To make our CPU, we'll...

Today we're going to talk about a fundamental part of all modern computers. The thing that basically everything else uses - the Arithmetic and Logic Unit (or the ALU). The ALU may not have to most exciting name, but it is the...

Today we're going to create memory! Using the basic logic gates we discussed in episode 3, we can build a circuit that stores a single bit of information, and then through some clever scaling (and of course many new levels of...

Today, we're going to discuss the critical role graphical user interfaces, or GUIs played in the adoption of computers. Before the mid 1980's the most common way people could interact with their devices was through command line...

Specifically, how that stream of characters you punch into your browser's address bar, like "youtube.com", return a website. Just to clarify, we're talking in a broader sense about that massive network of networks connecting millions of...

Today, Carrie Anne is going to take a look at how those transistors we talked about last episode can be used to perform complex actions. With just two states, on and off, the flow of electricity can be used to perform a number of logical...
