Today I want to talk to you about something I found in my desk drawer, that I find quite interesting. This. Any idea what that is? Well, it\u2019s a five and a quarter inch floppy disk. Why is it called a five and a quarter (<\/span><span style=\"font-weight: 400;\">5<\/span><span style=\"font-weight: 400;\">\u00bc) <\/span><span style=\"font-weight: 400;\">inch floppy disk? Well, firstly, it\u2019s five and a quarter inches across. One inch is two point five four centimeters (2.54cm), so this disk is approximately thirteen point three centimeters (13.3cm) across. Secondly, it\u2019s called a floppy disk because it\u2019s floppy. Floppy means soft or bendy. This is a very soft disk. You cannot use these disks anymore. This disk was used to store computer data on. It can save about three hundred and twenty kilobytes (320KB) of data.<\/span><!--more--><\/p>\n<p><span style=\"font-weight: 400;\">Next, we\u2019re going up in size. This was used in about the nineteen eighties (1980s), early nineties (90s). If you are as old as me, I\u2019m not going to tell you how old I am, if you are as old as me, then probably when you were at school, you used these in class. If you went to school in the nineteen nineties (1990s), you would have used these. This is a three and a half (3<\/span><span style=\"font-weight: 400;\">\u00bd)<\/span><span style=\"font-weight: 400;\"> inch floppy disk. This is still called a floppy disk, however, it\u2019s not floppy; it\u2019s pretty hard. It\u2019s called floppy, though, because the name stuck. This is a little bit bigger than this. Data size. Obviously, it\u2019s smaller. This can save about one point three megabytes (1.3MB). <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Okay? We\u2019re going up in size. You\u2019ve probably seen this disk, even if you\u2019ve never used one. If you use Microsoft Word, Microsoft Excel, any of the Microsoft programs, in the top left-hand corner of the screen the save icon is actually one of these. So even though you\u2019ve never held one, you may have seen one. After these disappeared, we started using these. That\u2019s a CD. CD stands for compact disc. This can hold about seven hundred megabytes (700MB) of data. Okay? So, we\u2019re getting bigger and bigger and bigger. Now, what\u2019s this? You\u2019ve probably all seen one of these. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">These days computers don\u2019t come with CD drives installed, but you can still use a USB flash memory stick. This is mine. You probably all use one. This one I\u2019ve got here is thirty-two gigabytes (32GB). They come in a whole range of sizes, from one gigabyte all the way up to hundreds of gigabytes. I first bought one of these about ten years ago and I bought one megabyte. Cost me a lot of money. Now they\u2019re very very very cheap. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">I also have this. That is a portable hard drive. It\u2019s portable because you can move it around. This is a one terabyte (1TB) hard drive. I bought this about five years ago and, again, it was quite expensive. These days the price has come down a lot, as always happens with technology. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Now, I\u2019ve talked about the sizes of these. What does all this mean? What is a kilobyte, megabyte, gigabyte, terabyte? Well, basically, what is a byte first of all. A byte is eight bits. That doesn\u2019t really explain anything does it? What is a bit? Well, computers all work on binary. That means they process everything in zeros or ones. When you look at your computer screen, the beautiful picture of the beach that you are seeing, is actually rendered entirely in zeros and ones. So, a computer can either say yes or no, on or off. That\u2019s it. And programmers use that binary to program all computers. Now a bit, one bit is one zero or one. That\u2019s it. So, a byte, which is eight bits, is zero or one, times zero or one, times zero or one, times zero or one, times zero or one, times zero or one, times zero or one, times zero or one. Which is basically two hundred and fifty-six (256) possible combinations of zero or one. And that is a \u2026 that is a byte. Okay? <\/span><\/p>\n<p><span style=\"font-weight: 400;\">And then we come to kilobytes. Kilo means a thousand. Kilogram. Kilometer. However, a kilobyte \u2026 a kilobyte is not actually a thousand bytes. It\u2019s one thousand and twenty-four bytes (1024B). And then we go up to a megabyte, which is one thousand and twenty-four \u2026 one thousand and twenty-four kilobytes (1024KB). And then we go up to gigabytes, which is one thousand and twenty-four megabytes (1024MB). Then we go up to terabytes, which is one thousand and twenty-four gigabytes (1024GB). And then we go up to \u2026 do you know what\u2019s next? PB? Petabyte. We go up to petabyte, which is one thousand and twenty-four terabytes (1024TB). So, my hard drive of one terabyte is actually not that big anymore. You can get hard drives much much bigger than this. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Okay? So, let\u2019s compare. Here, my floppy disk, from the nineteen eighties (1980s), and here, my terabyte hard drive, from about five years ago. How much bigger is this than this? Well, a lot of numbers, but I\u2019ve actually done the math for you, so you don\u2019t have to worry. Now, firstly \u2026 firstly, let\u2019s look at how much bigger this is than this. A one terabyte hard drive is thirty-one point two five (31.25) times bigger (let\u2019s get some red chalk) thirty one point two five (31.25) times bigger than my thirty gigabyte \u2026 thirty two gigabyte (32GB) hard drive. (Thirty one point two five times.(31.25)) Okay? Then the terabyte hard drive is one thousand four hundred and twenty-eight (1,428) times bigger than my CD. Yeah? And my terabyte hard drive is how much bigger than this do you think? It\u2019s seven hundred and sixty-nine thousand two hundred and thirty (769,230). Seven hundred and sixty-nine thousand two hundred and thirty (769,230) times bigger than this. So, how much bigger is my one terabyte hard drive than my 320-byte (320B) floppy disk? Are you ready? A big number here. It\u2019s three million one hundred and twenty-five thousand (3,125,000). Three million one hundred and twenty-five thousand (3,125,000) times. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">So, my one terabyte hard drive is three million one hundred and twenty five thousand (3,125,000) times bigger than this floppy disk. And this has happened in the space of twenty years. And this is where I get amazed. This is what I find absolutely wonderful. People who were using these at school, this was new technology. This was the top of technology. However, in twenty years, these have been superseded, in turn, by new technologies. And now this is the top, this is the best you can get. A one terabyte hard drive. In twenty years, what are we going to be using? In twenty years, how much data are we going to be saving? And this is what I love about technology. People who were using these twenty years ago, could probably not imagine or conceive of these. So, us using these now, we cannot imagine what is going to come next. And this is what I love the most about technology. And this is what I want to talk to you a lot about in the future: the fact that we cannot imagine, we cannot predict, we cannot understand what is coming in the future. Thank you. <\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>5\u00bc inch floppy disk Questions<\/b><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\">How big is a 5\u00bc inch floppy disk in cm?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: 3.3cm<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: 13.3cm<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: 33cm<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: 30.3cm<\/span><\/p>\n<ol start=\"2\">\n<li><span style=\"font-weight: 400;\">When was a 3\u00bd inch floppy disk used?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: 1980s<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: 1990s<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: 2000s<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: 2010s<\/span><\/p>\n<ol start=\"3\">\n<li><span style=\"font-weight: 400;\">Where will you have seen a 3\u00bd inch floppy disk before?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: At school<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: In your house<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: On a Microsoft program<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: In the 19080s<\/span><\/p>\n<ol start=\"4\">\n<li><span style=\"font-weight: 400;\">Why is it hard to use a CD these days?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: They aren\u2019t big and can\u2019t save a lot of data.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: They are too expensive.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: Computers don\u2019t come with CD drives any more.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: Shops don\u2019t sell CDs any more.<\/span><\/p>\n<ol start=\"5\">\n<li><span style=\"font-weight: 400;\">What is a bit?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: 256<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: 1<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: 0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: 0 or 1<\/span><\/p>\n<ol start=\"6\">\n<li><span style=\"font-weight: 400;\">What comes after Megabyte?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: Kilobyte<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: Gigabyte<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: Terabyte<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: Petabyte<\/span><\/p>\n<ol start=\"7\">\n<li><span style=\"font-weight: 400;\">How many times bigger is the 1TB hard drive that then 3\u00bd inch floppy disk?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: 31.25 times<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: 1,428 times<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: 769,230 times<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: 3,125,000 times<\/span><\/p>\n<ol start=\"8\">\n<li><span style=\"font-weight: 400;\">What is Steven\u2019s main point?<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">A: New technology is much too expensive.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">B: It\u2019s easy to see what technology will come in the future.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">C: We cannot imagine what technology is coming.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">D: The technology we have now is the best we will ever get.<\/span><\/p>\n<ol start=\"9\">\n<li><span style=\"font-weight: 400;\">Explain binary.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">What does Steven mean when he says, \u201cthe price has come down a lot, as always happens with technology.\u201d<\/span><\/li>\n<li><span style=\"font-weight: 400;\">How many times bigger is the 1TB hard drive than the 5\u00bc inch floppy disk?

People have tried to fly ever since they watched the birds soar in the heavens. However, it wasn\u2019t until the late 18<\/span><span style=\"font-weight: 400;\">th<\/span><span style=\"font-weight: 400;\"> century that people flew in hot air balloons. This seemed to energize people and within 60 years people were launching gliders. 128 years after the first balloon flight, the Wright brothers flew their powered plane for 259 meters. People then realized it was possible and the public got behind flight. Inventions and changes started to come thick and fast. The first jet engine was invented in 1928 and the first man flew in space by 1961. As with all technology, once the public gets behind something, and the money for research is available, the developments start to come at an exponential rate.<\/span><\/p>\n<ol start=\"13\">\n<li><span style=\"font-weight: 400;\">Try to imagine a piece of technology we might be using in twenty years.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">It is extremely hard to imagine future technology because, if you look twenty years into the past, current technology is so different as to appear alien. I think that one thing we might have in twenty years is 100% accurate face detection. Right now, airports use face recognition software, but it is not reliable. I think that this well be development and it will be 100% accurate. It will initially be developed by the American military but, once they see the potential behind it, companies such as Google will bring out their own versions. Right now, your Google search history follows you around the Internet. You searched for running shoes at home? Wherever you log on the adverts are for running shoes. But, Google can\u2019t reach you when you are not online. Well, with facial recognition software, they could. Imagine walking down the street and all of the signboards show you adverts for running shoes? I see that in the future.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\ufeff Download word docx\u00a0 \u00a0 Download MP3\u00a0 \u00a0 Listen to MP3 online Read below for script, questions and answers. 5\u00bc inch floppy disk All right, good morning everybody.
