## Series: Bitesize Coding and Computing

### How Computer Data Is Stored

Files are stored on a hard drive and are different sizes. In this clip, cartoon dinosaurs are used to demonstrate the size of files. It begins with bits that are made up of 1s and 0s. Eight bits make a byte, 1000 bytes make a kilobyte, 1000...Show More

### How Computers Have Changed

This episode takes a brief journey through time, showing how computers have changed over the years. From the mechanical calculator invented by Charles Babbage and programmed by Ada Lovelace, to Alan Turing’s algorithms which are still used in...Show More

### How Does the Internet Work?

How the Internet works is explained using the example of pigeons in their nests. All the pigeons, or computers, are connected together, and this is called a network. The rules of how the messages are sent are called protocols, and large messages...Show More

### How Search Works

Discover how search engines work through the example of a bear searching for honey in the woods. A search engine uses web crawlers to find information and send back a copy of each page. Algorithms are used to find the best match, and then the...Show More

### How to Break Down Problems

Decomposition is the process of breaking down a problem into smaller parts. Mr Moose’s problem is that he is hungry, and students find out how he could break down and solve his problem.

### How to Make a Computer Game

There are many different elements that go into making a computer game: deciding on the type of game, designing the pictures, animating the characters and choosing what will happen. We learn about why it's important to make sure that the game gets...Show More

### How to Make an Animation

This programme provides a basic introduction to animation, demonstrating how lots of pictures that are slightly different are put together to make it look as if a picture is moving. Pictures of a cat are shown in slightly different positions and...Show More

### How to Write Complex Programs

Complex programming is introduced using an example of a kangaroo that needs to have a drink without being eaten by a crocodile. The kangaroo needed to check that the crocodile was not near the water before she had a drink and she needed more than...Show More

### Using Computers at Work

Students will watch some examples of how computers are used day to day by ordinary people. They are used in shops, for taking photographs, in sport, for making music and films, to help us to learn, in aeroplanes and for going into space. What do...Show More

### What Are Computer Bugs?

This episode provides a basic explanation of what computer bugs are, describing them as mistakes in a computer program. A cartoon mouse and a robot demonstrate what computer bugs are. It also demonstrates the concept of bug-fixing in a simple and...Show More

### What Are Variables?

Variables are introduced using the example of a squirrel who wants to know where his nuts are buried, and how many he has. A variable is described as a special box that computers keep useful information in. There are two variables in the example...Show More

### What Is an Algorithm?

Algorithms are described as something very simple but important. They are explained as instructions that are split into little steps so that a computer can solve a problem or get something done. An example of how to brush your teeth is...Show More

### What Is Coding?

This episode offers a basic explanation of what coding is. In order to play games, do homework or talk to friends on a computer, programs are used. Computer programs are made using a special language called code, which is used so that the...Show More
