Crash Course Media Literacy

First thing’s first: what is media literacy? In our first episode, Jay breaks this question down and explains how we’re going to use it to explore our media saturated world
Database Applications

Database Applications

BBC Bitesize: Digital Technology

Databases are at the heart of digital technology, making data easy to store, organise and search.
Debugging

Debugging

BBC Bitesize: Computing

A simple explanation of debugging.
Digital Design Principles

Digital Design Principles

BBC Bitesize: Digital Technology

Digital design demands an understanding of computational thinking, as programming simply tells a computer what to do and how to do it.
Digital Data

Digital Data

BBC Bitesize: Digital Technology

What is digital data, and how do computers understand it? How is digital data represented, stored, shared and manipulated?
Developing Test Plans and Testing a Solution

Developing Test Plans and Testing a Solution

BBC Bitesize: Digital Technology

Once software has been created, it must be tested under different conditions to make sure it works. This can be achieved with white box, black box, unit, integration and system testing, as well as thorough planning and evaluation.
Contemporary Trends in Software Development

Contemporary Trends in Software Development

BBC Bitesize: Digital Technology

Software development and programming paradigms change over time, from imperative programming to high level languages like Python and C++.
Digital Applications

Digital Applications

BBC Bitesize: Digital Technology

The advent of digital technology has radically affected our lives, but what are the positive and negative aspects of those changes?
Database Development

Database Development

BBC Bitesize: Digital Technology

Developing the right type and structure of database allows you to store, access, search and output your data to your greatest advantage.
System Software

System Software

BBC Bitesize: Digital Technology

The functions of system software and their modes of processing, tasks carried out by utility applications, the role of antivirus software and the importance of regular system updates.
Spreadsheet Applications

BBC Bitesize: Digital Technology

Spreadsheets can help you calculate values from data using various formulae. They can also be used for data modelling and the visual representation of data.
Cyberspace: Network Security and Data Transfer

Cyberspace: Network Security and Data Transfer

BBC Bitesize: Digital Technology

Networks make computers more powerful, but also more vulnerable to attack. In the era of the internet and cloud computing, what are the threats to data security?
Multimedia Applications

Multimedia Applications

BBC Bitesize: Digital Technology

Multimedia applications combine elements like text, images, audio and video and require specific considerations in their design.
Programming Constructs

Programming Constructs

BBC Bitesize: Digital Technology

Computer programs use data stores to organise the different types of data they contain. Data stores can be either a constant, variable or an array, and contain inputs, outputs, functions, instructions, sequences and more.
Digital Data: Binary

Digital Data: Binary

BBC Bitesize: Digital Technology

The number system that computers use is binary. Binary is a base-2 system as it only uses two digits, 0 and 1. A binary digit, or bit, is the smallest unit of data in computing. All data (music, images, software) processed by a computer is stored...Show More
Testing

Testing

BBC Bitesize: Digital Technology

Software testing involves testing a program under various conditions to make sure it works. Even the best programmers make mistakes, so it is important that these are identified as soon as possible in the development stage so that errors can be...Show More

Ethical, Legal, and Environmental Impact

BBC Bitesize: Digital Technology

How does life, society and the law react to the evolution of digital technology?
Simple Error Handling Techniques

Simple Error Handling Techniques

BBC Bitesize: Digital Technology

In some ways, computer languages are no different to our own. They have strict rules programmers must follow in order to make their programs understood. Mistakes throw up errors, which must be fixed.
How Email Works

How Email Works

BBC Bitesize: Computing

A basic explanation of what emails are, what the email address means and how they are sent and received. Email addresses have a domain name which is after the @ sign. The last part of the address indicates where the address is registered, such as...Show More
Hardware

Hardware

BBC Bitesize: Digital Technology

Hardware is the physical components or workings of a computer system. It includes input, processing and output devices. The Central Processing Unit (CPU) can be thought of as the brain of the computer.
Evaluation

Evaluation

BBC Bitesize: Digital Technology

Appropriate use of coding constructs is evaluated to determine the efficiency of software as it relates to use of RAM. Software is measured against the functional requirements to evaluate fitness for purpose.
