1. During in-circuit tests (ICT) all components on the PCB are measured. In doing so, defective components are detected and can be replaced accordingly. Function tests (FCT) check the entire intended function of a PCB. According to the intended area of use, the environment is replicated and the electrical performance of the PCB is checked.
  2. ICT (information and communications technology, or technologies): ICT, or information and communications technology (or technologies), is the infrastructure and components that enable modern computing.

The following computer trivia fun facts were compiled by our technicians here at San Diego PC Help (we’ve been fixing laptops, tablets, cellphones, etc. since 1999.) Enjoy the list! Also be sure to check out the humorous 6 things you can do with your computer other than the obvious and our introduction to Net Neutrality!

A collection of fun ICT activities for children in key stage 1 and 2. This Trivia was originally posted in San Diego PC Help The following computer trivia fun facts were compiled by our technicians here at San Diego PC Help (we’ve been fixing laptops, tablets, cellphones, etc.

1. It took the radio 38 years and the television only 13, but the internet reached 50 million users in only 4 years.

2. The computer mouse was invented by Doug Engelbart in 1963. It was made out of wood (weird, huh).

3. In 2009 the average number of Internet transactions per second was 2,000. The total number of goods sold was worth $60 billion.

4. Early hard disks in personal computers held only 20 MB of data and cost around $800. In 2010 you could get a 2 GB flash drive for around $8. This implies that there is a 100-fold reduction in the price and a 100-fold increase in storage capacity.

5. Rear Admiral Grace Hopper, the first female admiral in the US Navy is also known in the computer world for creating the popular programming language COBOL. She also came up with the term ‘debugging’ after removing a moth from a computer.

6. The computing power in today’s cell phones is much higher than the processing power of all the computers in the Apollo 11 Lunar Lander that put 2 men on the moon.

7. The two main components in IT (Information Technology) are hardware and software. But there is also a lesser known ‘grey’ component. This is the software that is stored in hardware and cannot be modified easily. It is known as ‘firmware’.

8. There are over 20 billion web pages on the internet, and that number is rapidly growing every day. Also, there are over 2 billion internet users worldwide at present.

9. RIM (the BlackBerry operating system company) co-CEO and cofounder Mike Lazaridis dropped out of college to start his own company. He did so after reading Microsoft’s founder, Bill Gates’, book.

10. The first hard disk drive was created in 1979 by Seagate. Its capacity was a whopping (not) 5 MB.

11. HP, Google, Microsoft, and Apple have one thing in common – apart from the obvious that they are IT companies. They were all started in garages.

12. The 12 engineers at IBM that developed the IBM PC had a code name – “The Dirty Dozen”.

13. Free football videos. The first and still the oldest domain name to be registered is Symbolics.com, it was created on March 15th, 1985.

14. Most Central Processing Units (CPU’s) are sold as a bit slower than they actually run. By over-clocking them you can get them to run faster – for free.

15. The first micro-processor was the 4004, Intel had originally designed it for a calculator and no one had any idea to what it would lead.

It’s what the smartest, fastest and most intelligent machine on this planet can understand – Thing 1 and Thing 2. Okay, let’s be more precise – Zeros and Ones.

My inspiration behind writing this blog is my toddler child who thinks that software is something that is ‘soft’ and you can ‘wear’ it . As I was explaining to him about computers and software, I found that I need a refresher. I went back to reading the basics of Computer Science and Electronics. It would need years (and maybe a PhD) to completely understand the whole end-to-end process, but I am sharing as I am learning and hopefully this will peak your interest and encourage you to read or research further.

Let’s enter the computer’s world of bits and bytes. It’s your usual work day, you start your day with responding to emails, and later, maybe open your usual software and continue working. Little do you think of how exactly the letters you type on the keyboard get translated to your desired results. Or a few mouse clicks can help you navigate around and command the computer on what to do. Even a simple operation such as creating a new text file in notepad is quite mind boggling when you think deeper on what goes underneath. Basically, you are “telling” the computer in English that you need to save a text file, but your computer understands only 0 and 1. There is a HUGE translation gap. There has to be some translation which converts actions and commands to 0’s and 1’s so a computer can understand. Not only that, a ‘Save’ command will save text in 0 and 1 and will give it back in English when requested. This translation is super-fast, so much so, that it is under appreciated and taken for granted! Luckily computers are just machines so they don’t get emotional ;P but let’s just do our part and pay some attention to the grand scheme behind clicks and typing.

We can break end-to-end processing into 3 major steps:

  • Translation to Binary
  • Saving commands in the Memory as Binary
  • Executing Binary commands using CPU

Translation to Binary

Before we talk about Translation to Binary, let’s look at what exactly is ‘binary’ i.e. 0 and 1

What is 0 and 1?

Thing Thing 1fun In Ict Igcse

When we say that information is consumed and stored in computer form of 0’s and 1’s, there is literally no 0 and 1 written in the memory like we write it on a paper. 0 and 1 can be interpreted as absence and presence of something. In this case, it’s electric charge since we are dealing with electric circuits.

Why is Translation needed and how is it done?

Translation is done by Operating Systems and Compilers. We use keyboards, mice, voice commands, etc. to interact with a computer, but this is all gibberish since computers cannot understand it. An Operating System is the bridge between computer software and hardware. Along with converting commands to 0’s and 1’s, it oversees that all running programs get what they want in terms of CPU time, resources, and memory. So, all our physical actions or interactions eventually get written into a series of electric charges i.e. 0’s and 1’s. They then either get stored into a RAM or hard disks. Also, code written in high level languages (closer to human language) compiles and translates to machine language. In short, all eventualities will lead to conversion of commands into 0’s and 1’s.

In my next part, we will continue our journey and see what happens to the translated actions and commands. If you have any questions in the meantime, don’t hesitate to contact KTL Solutions at 301-360-0001 or by emailing, [email protected]
