H/W 2 – Wi-Fi
What is wireless internet (Wi-Fi)?
Wireless networking - which is often just known as Wi-Fi - is a way of getting broadband internet without wires.
Wi-Fi allows you to connect several computers at once, anywhere in the house - or if you have a laptop, to even use your computer in the garden. You don’t need to install extra phone lines or cables.
Millions of Britons already connect to the internet using Wi-Fi – pronounced ‘why-fy’. It’s also known as ‘wireless networking’ or ‘wireless fidelity’.
Wi-Fi is widely installed in cafés, airports and many other public buildings. If you have seen someone at your local coffee shop surfing the internet on a laptop computer, they are probably using a Wi-Fi network.
How does Wi-Fi work?
Wi-Fi creates a network in your home or office – a little zone where computers can get broadband internet. It uses radio waves, just like TV or mobile phones. You may sometimes hear this zone referred to as a WLAN (Wireless Local Area Network).
A device called a wireless transmitter receives information from the internet via your broadband connection. The transmitter converts the information into a radio signal and sends it.
How do I set up
Wi-Fi?
To use Wi-Fi you will need certain equipment:
• A wireless transmitter, also known as a Wireless Access Point (WAP) – A router has a WAP built-in!
• A Wi-Fi adapter on every computer/tablet/phone that will use Wi-Fi.
Many ISPs will supply you with a router, modem and wireless transmitter combined in one device, which it calls ‘the router’. To make your Wi-Fi set-up as simple as possible, you should consider using a similar device.
The router plugs directly into a phone socket and doesn’t need a computer to run it, so you don’t have to set up your computer next to the router.
Computers – mainly laptops – increasingly have built-in Wi-Fi receivers. If not, the simplest method of installing a receiver is a dongle - a little device that plugs into a USB port and transmits between your PC and wireless router.

Bob is a photographer from Bolton. He takes a lot of pictures and likes to share them with his friends. He travels round the world a lot and sometimes finds that his memory card on his camera fills up very fast and he cant take as many pictures as he’d like. When he is back in England he uses both his work computer, his laptop and his home desktop to edit and print the pictures. He has a very fast internet connection and no download limits.
How might cloud computing be useful to Bob? Explain your answer.

H/W 5 – Accessibility 2
Picture this: You roll out of bed in the morning, stumble over to the kitchen and call out, “Alexa, turn on the TV.” Good, background noise is on. Time to make some coffee. You fumble around with your coffee maker and suddenly remember that you still don’t have a gift for your niece’s upcoming birthday. Oops. “Alexa, order a chocolate gift box from Prime Now.” You listen to the product options, choose one, and confirm your order. Done. That was a close one. Technology sure is helpful. Now imagine this scene all over again, except this time you’re visually impaired.
For many able-bodied folk, virtual assistants are just another cool way for technology to make us feel like Tony Stark. But for many individuals with disabilities, it’s a complete game-changer. From placing phone calls and texting their caretakers to unlocking front doors and ordering groceries; virtual assistants are making important steps towards accessible UIs for the masses.
In 2015, Jamison Hill lost the ability to speak and could no longer use his beloved Siri for essential, everyday tasks. He could still use Siri’s “Speak selection” tool to read emails or articles, but he couldn’t say, “Hey, Siri” to do what everyone else does on a whim. Then came along Google Assistant with its uncreative name and a whole new option to use either voice or text commands. It immediately made Jamison’s life easier. He could now type in medication reminders, look up his doctor, and even order medical supplies online. Sure, he can also do these tasks manually, but virtual assistants just make it so much easier.
While Jamison maintains that the perfect assistant doesn’t exist, they have certainly improved his life. Although his particular case is a stark reminder to the designers and developers of virtual assistants that there are many other disabilities to consider. “I use Amazon Echo to control music, TV, and do math”
Annie Segarra, a Youtuber and activist for an accessible future, explained in an ad-hoc Twitterview how she mostly uses Alexa for entertainment and mental health purposes. From playing music and controlling the TV to solving math questions.
Alexa has been quite the asset for her daily tasks and Segarra is already planning on purchasing all the extra knick-knacks to give Alexa even more control. Although she does point out that sometimes voice commands are difficult to give during flare ups where even talking is a “mountain-like task”.“Alexa has become an invaluable part of my ecosystem”
Amazon’s Alexa allows short voice commands like “Timer, 15 minutes” instead of “Hey Google, set a timer for 15 minutes.” A resounding benefit for those with cognitive disabilities.At this point, it’s safe to say that virtual assistants are far from being the perfect solution for every person with disabilities, particularly for those with speech impediments. They do, however, present a unique opportunity that can be leveraged by many disabled users to help them accomplish daily goals and overcome everyday challenges. But are AI developers actively considering disabilities during their process? Or is it more of an afterthought?

Quiz Score attained: ____ / ____
Read and digest the information below. You will be quizzed next lesson!
#1: Failing MemoryYou drive while talking on the cell phone, text while listening in on a conference call, surf your iPad while watching TV. Multitasking is the new normal, and though it feels like we’re more efficient, studies show it has the opposite effect.“Your performance level drops if you stop one activity to pick up another,” says Gazzaley, who conducts ongoing studies on the effects of media on our brains.SOLUTION – Have breaks and spend time off the phone. Engage in activities such as reading, off-screen!
#2: Strained VisionAbout 40% of optometrists’ patients experienced eye strain due to computer vision syndrome (conditions related to “near work”), while 45% complained of neck and back pain associated with computer or handheld device use, according to a survey.Many computer users assume awkward postures to position their eyes for better performance, according to the association.Close computer work can cause light sensitivity, dry eye, blurred vision, double vision, fatigue and headache.SOLUTION – Limit time spent continuously in front of a computer. Adjust the top of your monitor at eye-level. Avoid nodding head up and down.
#3: Hearing LossCan you hear me now?Probably not well, if you blast music through earbuds for long stretches, says Brian Fligor, D.Sc., M.S., director of diagnostic audiology at Children’s Hospital in Boston and an instructor at Harvard Medical School. Wear and tear on ears is normal, resulting in some hearing loss in seniors. But what you do early in life sets the stage for how well you’ll hear as you age, Fligor says.SOLUTION – Make sure you earbuds fit snugly. Limit your exposure to loud music.
#4: Muscle and Joint PainOn average, we send and receive text messages 3,339 times a month, according to a 2010 Nielsen Company survey.In Britain, about 3.8 million thumb-typers complained of pain from similar activities. Nearly 38% said they suffered from sore wrists and thumbs, the result of repetitive movements, according to a 2006 survey by Virgin Mobile, a British cell-phone company.SOLUTION – Avoid sending text continuously as it may hurt your hand and neck tendons. Rest your arms on a table to relieve neck and shoulders.
