Basic Principles of Communications Systems (3667-02: Unit 101)

I finally doing the City & Guilds Course to learn about the Data Cabling, however this one is an essential core course. I am not going to mention the company name unless they want me to, however they are very excellent Training providers.

The last time I done City & Guilds was over 20 years ago when I was doing my NVQs.
It was boring as this is all theory but it is a core subject and boring are the essentials unfortunately if anyone reading this:

I learn new things such as:

- The PUWER rules (Provision and Use of Work Equipment Regulations 1998). This is where the user is responsible for the work tools and equipment. Using the correct tools which is intended to do for the task. 

-Using the correct voltage between 110v vs 240v. Recommend 110v tools.
Ladder 4 to 1 rules. 4 meters per 1 meter wide. Basically when you use the ladder, it is about how to use it correctly or else you fall.

- Asbestos - When you go to sites to do cabling, you have to learn about asbestos as you be going across ceilings and walls, mostly ceilings to wiring as you be feeding the cables between the ceiling and walls.

- Classes of Laser, there are 7 classes of lasers from low to high. High laser class is more dangerous than the other.

- I learn about the Health and Safety, identify the safe practices, learn about the SI Units and symbols and principles of data communication.

- Ohms law

- Wavelength

- Types of cabling we use such as coaxial to ethernet. Also mention about Fibre Optic.

I done the exam and I failed by 1 question which is unlucky for me as it was close.

Update on 8th April:
I did a retake of the exam which I failed at the time and manage to pass with flying colours. What a comeback. I finally pass both exams which I am now relieved.
