Getting into computers for the first time can be tricky, the jargon can be a pain in itself.

The key is not to be intimidated, computers are for everyone. A good book of course is always useful as a guide and here at Pckernow we will try and help if you live in the South East of Cornwall or Plymouth.

Computers though can be fustrating, even for the professionals, so please remember you are not alone, and if you find yourself getting annoyed by your laptop, desktop, smartphone or tablet, just remember we all do!

Below you will find some guides to computers, which I hope will be useful. Over time we hope to add some set up guides. Feel free to visit this site, to keep up to date.


  1. CPU – Central Processing Unit – The brain, used to control the computer, process your work, and do calculations. The faster the CPU, the better.
  2. Ram – Random Access Memory – used for the quick processing of data. The more RAM, the quicker the computer generally is.
  3. Hard Drive – used to store all the data on the computer, such as photographs, files, music.
  4. GPU – Graphics Processing Unit. – Used to display images on the screen quickly. Some computers have separate GPU cards, while some are included on the motherboard.
  5. Motherboard – The main circuit board, that links all the parts of the computer together. The CPU, RAM and GPU all attach to the motherboard.
  6. Cache – a quicker version of RAM, normally attached to the CPU.

A Human Guide

A computer can be hard to understand, so many terms, CPU, RAM, motherboard for example. Some of my customers have found the following human analogy useful.

Picture the CPU, (Central Processing Unit) as the equivalent to our brain, and the RAM, (Random access memory) as where we do our day to day thinking. The RAM is quick, but cannot store much information and not permanently. The hard drive is where we store our old memories in our brian, we can store more information on the hard drive, but it can be slow to get to. The motherboard is what links our body together, allowing each part to work in a useful manner; in a computer the motherboard connects the CPU, RAM, Harddrive and other components together.

So if you were going shopping, you may store your shopping list in your RAM, but if we were asked about our child hood memories, we would resort to our hard drive, while the CPU would allow us to carry out the actions like communicating, shopping, walking and talking.

I hope this analogy helps.


Thinking smart and ahead of those trying to trick you is the key to safe computing. There are a number of individuals who sadly try to destroy the wonderful benefits computers can provide to humanity.

These individuals will do everything to get you to give them your passwords, bank details or just destroy your data.

It is incredibly annoying, time wasting and can leave you a little scared to turn the computer on.

Don’t be scared, just think smart. I have mentioned already on this site the simple rule – if I would not do this with my car or house, then don’t do it with your computer. In effect, if a letter came through your letter box, saying you have won a million pounds and all you have to do is send your bank details, would you?

The chances are you would not. The same logic applies to an email, asking for your bank details or passwords. Ignore them, delete them and if you feel it is criminal report it.
