Technology: Are we afraid?

C’mon let’s be honest, we all have to use technology on a daily basis whether we like it or not. Are we afraid of computers?

Whether you’re working in computing itself or other professions, computers are now a crucial part of our lives.

For decades now, Computer Scientists have found new ways to make technology useful, from handheld devices like mobile devices to servers and super computers. Over the past 10 years, CPU’s have got up to 60% quicker! Although, it’s not just the CPU component that has boosted the speeds of these monsterous machines. With SSD’s being more commonly used in more machines, we can get data in mere milliseconds. Again, it’s not just these components that have made our computers react like lightning bolts.

Personally, I’m mainly afraid of something if i don’t know how it works. With that in mind, let’s take a look at the inside of a computer:

Let’s think of it like this, the CPU (Central Processing Unit) is the ‘brain’ of the computer. It takes what is inputted into the computer and gets it ready for output. The speed of processors are measured in Megahertz(MGz) or Gigahertz(GHz) — Mostly Gigahertz now due to ever increasing speeds. If a computer has a 3GHz CPU, this means it has 3000000000 pulses per second — this a fairly powerful CPU.

RAM(Random Access Memory)is used for temporary storage. It is used for information from the CPU that needs to be used quickly. If there is a power cut or the computer is turned off, the data in the RAM will be lost.

A hard drive is used for storing data permanently, so like all the programs on your computer and your operating system, along with your files.

PSU stands for Power Supply Unit, this is fairly self-explanatory :).

Graphics Cards are so the computer can provide a visual output so you can see what the computer is doing on some sort of screen or display.

The Motherboard is to connect all these components up so that they can work together, and also has very important chips to tell the computer what to do on boot.

Machines are also getting smaller and smaller with the idea of nanoparticles and nanotechnology coming into play. George Tulevski has done a really interesting talk on how computer scientists hope to soon get this working.

In addition to this, computers are being used by all sorts of digital makers to make so many different and amazing things. Here’s an example of Bethanie Fentiman’s Pi Wizard chess! To learn more about her, Wizard chess and her raspberry jam in Kent click here.

Think about it, who made this though? Us. We did. Humans. Man kind. Earthlings. Can we really be afraid of something we have made and developed ourselves? I don’t think so. We need to embrace this generation of digital making and computing — there’s no time like the present.

Don’t fear what is happening, embrace it!
