Telecommunication and Networking

Wow!!! It is a brand new semester, new beginning and new hope for me. Everything gonna be change. Frankly, I see the difference in me when compared the PAST and PRESENT. Somehow it is a good sign. I realise myself growing up rapidly within these couple of months in the sense of I becoming more independent, stronger and tougher. I learn how to face difficulties and challenges in my life with a smiling face.@.@ It is also definitely a chance for me to learn how to appreciate my FAMILY. They are pretty essential to me as they are my supporters wherever I go and we share happiness and sorrow together.



      I really can't imagine myself I will write a blog as it is not my style. However,  I am glad that I have the opportunity to try something new.yaa.. thank you, Dr. Dayang! All of you might wonder who is Dr. Dayang. Well, before I introduce Dr. Dayang, please give her a big round applause first..xD She is our Telecommunication and Networking (SPPM 1013) lecturer. The first impression I get from Dr. Dayang is she is very friendly, cute, has a sense of humour and dedicated. She tries to remember all her students' name as she cares for us. She is also being an understandable person whereby she puts herself in her students' shoes. That's great!





Okay, back to the topic. What have I learnt for today's lesson? Today is the second lesson for telecommunication and networking class whereby Dr. Dayang starts the class by briefing us the individual and group assignment.(yup..it's a bit tense up). Next, Dr. Dayang gives us lecture on 'Introduction to Telecommunication and Networking'. For me, telecommunication and networking becomes more and more popular especially in this world of globalisation. Even a gorilla dwelling in a jungle know how to use ipad 2. It is pretty amazing!





Below are the summarize of mine for today's lesson:

  • What is the meaning of 'communication'?
- Communication is the process of imparting, conveying /exchange of thoughts, messages, ideas, knowledge /information by sign and sounds like speech, signals, writing/behaviour.
- Communication can be said as complete once the receiver can get the meaning from the sender.
- Communication is effective when there is an interaction between the two communicating parties.

  • What is the meaning of of 'telecommunication'? (tele = far off)
- Telecommunication is a form of communication over a long distance whereby transfer of data (communication) from a transmitter to a receiver across a distance is occured.
- The data/code for telecommunication is represented by some form of electromagnetic energy: electricity, radio, waves and lights which are transmitted through medium: wire, cable and atmosphere.



  •  The 6 elements of computer and communications technology:-
1) People       2)Procedure   3)Data/Information
4)Hardware   5)Software     6)Communication/Connectivity 

However, the most important element is the PEOPLE. Without people, there is no point for us to communicate.

1) People
- user of the computer
- built, analyse and develop the system
- 2 categories of people:
  i) Professional: Those who have gone through specialised training in theory and technical                aspects.e.g.programmer, computer engineer and etc.
 ii) end user: Those who know how to use without training. e.g.clerks, teachers and etc.

2)Procedure
- an orderd set of tasks for performing some action.
- a clear specification for the sequence, training, execution of a process.

3)Data
- information stored on the computer system, used by application to accomplish task.

4)Hardware (equipment/devices)
- physical object that are part of computer syatem.
- basic operation of computer system.
- 5 categories of ICT equipment: IPOSC

I = Input   P = Processor  O = Output  S = Storage C = Communication

5) Software/Program
- 2 categories: i) system software (e.g. Window, doc and etc.)
                       ii) application software (e.g. antivirus, Microsoft Office and etc.)
- instructions that control the functioning of the computer.

6) Communication/Connectivity
- is the transmission of data (electonic data)
- is the conversion of data analog-to-digital and digital-to-analog.

That's all from me. Thank you!!!Looking forward to the next class.


To be continued...stay tuned yaar...
