In the final episode of the series, Justin Webb and guests discuss how the role of president has changed - and what the winner of the vote will be able to do once in office.

In the penultimate episode, Justin Webb and guests discuss what happens on election day -- and how the notorious electoral college system works.

Justin Webb and guests reach episode 3 of this guide to how the US elections are run, with a look at the historical and contemporary importance of the TV debates.

Following on from part one, which explained how the candidates are selected, part two looks at what happens on the campaign trail - and who's paying the bill?

Justin Webb, former BBC US correspondent and co-presenter of Americast unpicks some of the terminology associated with the US Election.

What role have the USA and Iran played in the region? Where do we stand on the 'two-state solution'? Katya Adler and guests explain the history and context of the decades long conflict between Israel and the Palestinians and assess what happened to the peace process. In this episode we set out how global players have tried to influence the region at times of peace and at times of war.

How do Lebanon, Hezbollah, Egypt and Jordan view Israel and the Palestinians? Katya Adler explains the history of the formation of Hezbollah and the role it plays in the region. The US, UK and EU have designated Hezbollah's military wing as a terrorist organisation but how is it viewed in Lebanon and the region? We take a tour of this Middle Eastern neighbourhood to set out the relationships that could determine the future of the conflict.

What is Hamas, what do they stand for and what do they want now? As part of our series explaining the context of today’s conflict, Katya Adler and guests take a closer look at the group responsible for orchestrating the recent attacks on Israel. They are regarded as a terrorist organisation by Israel, the US and the UK, but how are they seen by Palestinians? As well as being a militant group and an Islamist movement, they are in charge of governing more than two million people in the Gaza Strip. How did they come into being and what are they hoping to achieve?

Katya Adler and guests explain the context of the conflict, exploring issues and history that will help you get to grips with what’s going on today. In this episode we'll look at what’s shaped modern Israel

Katya Adler and guests explain the history and context of the decades-long conflict between Israel and the Palestinians. In this episode we focus on life in the Palestinian territories of the Gaza strip and the West Bank and explore the history of how the state of Israel was created.

When so-called "generative" Artificial Intelligences like Chat GPT and Google's Bard were made available to the public, they made headlines around the world and raised fears about how fast this type of AI was developing. But realistically, what harm could AI do to people? Is it an existential threat, or could it become one? And if things got really bad, couldn't we just switch it off or smash it up with a hammer? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree. This series is your chance to get back to basics and really understand key technology terms. What's an algorithm? Where is "the Cloud" and what exactly is Blockchain? What's the difference between machine and deep learning in artificial intelligence, and should we all be using Bitcoin? Our experts will explain in the very simplest terms everything you need to know about the tech that underpins your day. We'll explore the rich history of how all these systems developed, and where they may be going next.

AI is now able to do some types of work faster and cheaper than human beings, and some workers have already found themselves out of a job. Earlier this year, a report from Goldman Sachs said that AI could potentially replace the equivalent of 300 million full-time jobs, and a different survey of 12 thousand people suggested that a third were worried their bosses would replace them with AI. So is AI coming for your job? What type of workers are most at risk, and if you aren't replaced, could you find yourself working alongside an AI? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree. This series is your chance to get back to basics and really understand key technology terms. What's an algorithm? where is "the Cloud" and what exactly is Blockchain? What's the difference between machine and deep learning in artificial intelligence, and is it just jobs under threat, or is it much worse than that? And before we get to the destruction of humanity, should we all be using Bitcoin?

At its simplest, an algorithm is a sequence of step-by-step instructions designed to give a result. They are the building blocks of every computer program and are there to ensure every digital device gives the right results on request. For example, when we type a search query into Google, its algorithms try to give us the result we're seeking. In the case of Social Media, the algorithm's job is to keep followers on a platform, by showing engaging, interesting, and relevant posts. But over the years they’ve increasingly been entrusted with life-altering decisions, such as A-level results during the pandemic. So how are algorithms being used? Why do many people distrust them, and try to beat them? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree.

Artificial Intelligence is already here. It's being used in products and services you already use, and is working behind the scenes in medicine, transportation, robotics, science, education, the military, surveillance, finance , agriculture, entertainment, retail, customer service, and manufacturing. How is is AI being used in these sectors, and for what purpose? And with the release of chatbots that can emulate human writing, we're now seeing websites that say they're "powered by Chat GPT". What does that mean? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree.

Artificial Intelligence has been in the news constantly this year, from a chatbot that can write anything you can imagine, in any style, to scientists and world leaders warning that AI needs to be controlled. With the big tech firms all rushing to make their AI products available to the public, it looks like AI is likely to be part of our lives from now on. But what is it? What are the different types of AI we should know about? Are they intelligent, in a way we would recognise, and are they conscious? And what does machine learning mean? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree.

Big data is vast, unwieldy information that is so huge that normal software traditionally used to analyse it just can't cope. It's not new. Ever since humans organised ourselves, we've been keeping records, and gathering information, from scrolls, to bank ledgers and now your internet browsing history. But his information is now flowing into organisations at a faster rate and in greater volume than ever before. Taking a good look at it could provide meaningful insights. But how can you spot patterns in the chaos, without the job taking forever? And what insights could this mega data analysis provide?

You might be wary of using digital currencies, but you probably already do. Salaries, benefits and pensions are now paid direct to banks, and when you buy a coffee, you may well use a contactless card to pay, without a flutter of a 5 pound note in sight. So what are online cryptocurrencies like Bitcoin, and why won't some people touch those with a barge pole? And when you hear about them, another word always pops up - Blockchain. What does it do? And how could both become important when we start to use the next version of the Internet, called web 3.0?

Just by putting on a headset, Virtual Reality promises to immerse you in another world, and Augmented Reality takes that world and brings it into your living room. How do they work? It's a type of technology that seems to have been "the next big thing" for at least a decade. But are they just expensive toys, or do they have a use beyond gaming? In a similar vein, you may have seen adverts for the Metaverse, and that Facebook's parent company is pumping huge amounts of money into it. But what is it? How are Virtual Reality and Augmented Reality linked to the Metaverse, and will they make it...a reality?

We all get that sinking feeling when we accidentally delete a valuable photo or document, but there's now a good chance you can find a backup copy - thanks to the Cloud. Cloud computing has drifted into our lives without many people even realising - apart from those irritating emails, offering to sell you ever greater amounts of storage space. Some laptops now have very little memory built-in, and rely on the Cloud to store files. But where does it all that information go? What does the Cloud look like and where exactly is it? How are vast amounts of computer memory and processing power being put to use? And are those precious photos of your pet cat being kept securely?
