250 Billion emails are sent out daily

No, these shocking numbers aren’t triggered by humans. The surprising fact is that 81% of all emails are spam which is sent using automated means. That’s a whopping 200 billion spam emails every day. The first spam email was sent back in 1978, it was an advertisement for a presentation by Digital Equipment Corporation for DEC System 2020. The email contained 600 recipients, and none of them were happy to receive it.

Cyber Terrorism and DDOS

The most common form of “cyber terrorism” is a DDOS, or Distributed Denial of Service attack, whereby hundreds if not thousands of systems around the world simultaneously and repeatedly connect to a website or network in order to tie up the server resources, often sending it crashing offline. Anonymous released a tool this year that users could download and set on autopilot to receive attack commands from a remote command source. Similar DDOS attacks are often performed by the use of malware installed on users computers without their knowledge.

400 hours of video are uploaded to YouTube every minute

By the time you reached this paragraph, 1600+ hours of video content have been uploaded to YouTube. Speaking about user engagement, the massive video sharing site serves more than 1 Billion people every month, and an average internet user spends 4 hours every month on YouTube. Looking at such stats, Google has taken massive steps to protect copyrights of individuals by scanning over 100 years of video contents every day using complex software.

Counting Starts at Zero

At a base level, every computer’s just a really big, complicated calculator. But thanks to the way its intrinsic circuitry works – with lots of little logic gates that are either ‘on’ or ‘off’ – every action that takes place at a base level is happening in binary, where things are either a 1 or a 0, with no shades of grey in between. This actually translates up to a neat bit of programming trivia – in the computer science world, all counting (with the rather notable exceptions of Fortran and Visual Basic) starts at zero, not one. It actually makes a lot more sense – ever thought about why the 20th century refers to the 1900s? It’s because when historians decided on the dating system, they weren’t clever enough to call the very first century (0-99AD) the 0th century. If they had, we’d probably have far fewer confused school children the world over.

The work that goes into a Ctrl+C, Ctrl+V

One rather under-appreciated fact about solid state drives (SSDs), regarded as the gold standard for fast, reliable storage, is the amount of copying they have to do. When you want to copy some data from one bit to another, it’s not just a matter of shuffling the data from one part of the drive to another. Because of the complicated way a SSD works, over-writing a block of old data with some shiny new data isn’t as simple as just writing the new stuff in with a bigger, thicker Sharpie. Rather, the storage drive has to do some complicated shuffling around. In practice, this can mean that writing a tiny 4KB file can require the drive to read 2MB (that’s thousands of times more data that the 4KB file you’re trying to write), store that temporarily, erase a whole tonne of blocks, then re-write all the data. It’s rather labor-intensive, so think before you juggle your files around next time.

The distance data travels

A quick experiment for you: click this link, which should take you to Wikipedia. With one click, you’ve just fetched a bunch of data from servers in Ashburn, Virginia, about 6000km away. Your request has traveled from your computer, through a local Wi-Fi router or a modem, up to a local data center, from there onward (under the Atlantic Ocean, if you’re in the UK), all the way to Virginia, and back again – in around 0.1 of a second, depending on how good your internet connection is. By comparison, your body takes around 0.15 of a second for a signal to pass from your fingers, up your spinal cord to the brain, and back down again.

Bits, Bytes, and Size

Next time you complain about the pitiful memory capacity of your old 8GB iPod Touch, it’s worth remember what makes up eight whole gigabytes. Computer science grads will know that in every gigabyte, there’s 1024 megabytes; 1024 kilobytes in a megabyte, and 1024 bytes in a kilobyte. Breaking it down to the lowest level, you’ve got 8 bits in a byte.

The First Computer Virus Was Created Out Of A Clean Heart

When computers are harmed by viruses, usually there is some malice behind their creation, but not on this occasion. In 1983, Fred Cohen, who is known as the inventor of computer virus defense techniques, made a parasitic application that would infect computers. He called it a computer virus and the virus’ primary function was to infect a computer, and make copies of itself by spreading from one machine to the other through a floppy disk. The virus was not created out of pure malice or some revenge scheme, but to show to the world that such a thing was definitely possible and that appropriate measures should be taken in order to counter such threats. Looking at the slew of computer viruses that are harmful to our machines, we would assume that his advice was not taken seriously, despite the fact that we have a plethora of antivirus programs at our disposal.
