But unfortunately, I missed the Quiz 1 on that day...
I will make sure that for the next time I can attend the other quizzes successfully. Fighting!]]> 2018-09-19 14:33:29 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/283453103 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/283460162 Today is the first class of STIV 3023 Multimedia System Networking (Group B) , Lecturer ask us to download the Padlet, Quizlet and HP Reveal and this is my first attempt to use these app.]]> 2018-09-19 14:45:13 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/283460162 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/283462355 Today is Hari Malaysia !!!!! No class for today but we need to attempt the Quiz 2. After I have study about the note that will come out for Quiz 2 but I still don't understand a few sub topic such as the different between network and multimedia network, what is standard and so on... When I'm answering the question I still in confusing about that.]]> 2018-09-19 14:48:26 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/283462355 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/283468436 We have discuss a few things on today class:-
1) Finally, I understand about the different between network and multimedia network. Why we use the multimedia network, it is because nowadays most of the document like video, image, animation need more larger storage and speed to upload or transfer. These type of document consist larger data so we can't use the normal network. For the network, it doesn't contain the highest speed to transfer big document.
2) We know the type of network and what is standard. For example, if no standard, Iphone can't connect with Samsung. 
3) Today we also have discuss about our Assignment 1 and we had form a group of 5 person in our group.
4) Lastly, I think the most interested thing is we play the Quizlet.live. Although our group did not answer the question correctly but I still found it very interesting. I hope that I can play next time.]]> 2018-09-19 14:57:43 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/283468436 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/284771107 We have learn the chapter 2 on today lesson.
1) I know that the requirement of networking is same with the multimedia networking.
2) Most of the programmer will use Window and for designer will more prefer Apple.
3) Virus (.exe), Apple (.dmg)
- Finally, I'm understand that .exe is a virus file, next time I will pay more attention to avoid computer got virus.
- Besides that, lecturer also ask use to find " Why hacker create virus (.exe), not for (.dmg)?
4) At least 2 host when communicate with each other, one is sender and one is receiver. How to differentiation the host? It is different by IP address.
5) Server is like a heart, if off, all the device will goes down. Moreover, server is protect by firewall.

We also learn about the network topology. What is network topology? It is means arrangement of network which include nodes. At the end of the presentation, our group is consider Star topology is more suitable. But we also prefer what the other group say that it is depend on the situation, all of the topology have their advantages.

Last but not the least,
* Don't skip breakfast
* Stay positive and always say thank you x3
Hahahahaha this is what lecturer had tell us and I totally agree!]]> 2018-09-23 17:12:35 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/284771107 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/292065721 What have I learned today?
1) Bandwidth vs Throughput
 - In general, both of them have same definition which means how fast the internet connection.
- However, they also have different places which is :
Bandwidth is how many data can travel from one location to another location per second.
Throughput is how much data is actually travelling from one location to another location per second.
-  Why cause the different between bandwidth and throughput. This may cause by the user is too many, the internet is slow, the different device have been used, different type of cable and so on.
2) Type of cable:
- Glass cable transfer in light.
- The other cable transfer in electric.
3) Open system Interconnection (OSI)
- what happen when you use World Wide Wed(WWW), Whatsapp and so on.
- There have 7 layer, which start from layer 7.
- It need to go through one by one, cannot skip any layer.

Besides that, we also have discuss about the Assignment 2]]> 2018-10-12 08:36:28 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/292065721 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/292074092 Today we had online class by using Edpuzzle. This was my first time to use Edpuzzle. It was very interesting. We had saw a lot of video and answer the questions.]]> 2018-10-12 09:09:00 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/292074092 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/292079512 We have an online quiz on Online Learning today.

Besides that, we also need to fill in the narrow topic for our Assignment 2. For our next lab class, each group need to prepare and print out 3 pictures and video which represent the copper cable, fiber cable and wireless. It must different with other group. 
For our lessons today, we have learn the network security. It represent what are the things that user can do and can't do in order to ensure the network safety. What are the things that need to protect. For example, UUM need to protect student's information, result and so on. In addition, security policy is a living document and need to update time to time. The security policy components must include in our final project. There have 3 component which is Governing policy (pihak-pihak atasan, such as HEP and UUM's decision maker) , Technical policy (UUM IT) and End-user policy (Lecturer, student and so on) .

We have learn about AR in 2D by using HP Reveal. It's like Pokemon Go. The video will appear when we scan on the picture by using HP Reveal. It is very interesting!]]> 2018-10-12 09:56:50 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/292086655 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314235654 Today we didn't have class because it is mid-sem break!!]]> 2018-12-13 13:41:46 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314235654 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314236263 Today we still didn't have class because still in mid-sem break, but we will start class on next week. ]]> 2018-12-13 13:43:01 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314236263 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237441 Today we need to participate in the Edpuzzle's online class. The topic that we have learn is Network Security Project. We need to read the slide that provide in the Edpuzzle and answer the question.  We have learn the security policy component which are Governing, Technical and End-user. Besides that, we also learn the purpose of the networking security. I have done the online on that day although Dr. Harry have open the class until tomorrow  22/10 (Monday).]]> 2018-12-13 13:45:29 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237441 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237553 Today our lab session will be conducted online as a quiz. Fortunately, Dr Harry has remind us the quiz must be accessed via quiz.uum.edu.my. Otherwise I will go to the online learning and find the quiz. The quiz is about the topic Network Security Policy which we have learn in last online class. There are 5 question that we need to complete and all are in structure form.]]> 2018-12-13 13:45:45 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237553 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237662 Today we have learn about Multimedia Info Representation. Multimedia Info can be represent as multimedia element which include text, audio, video, image, animation and interactivity. Before Dr Harry told us that there were 6 multimedia elements, I thought there were only 5 because I didn't know interactivity also include as a multimedia element. Text and still image are not time to time while for the audio and moving image are time to time which means they will change. There have 1 question that asked by Dr Harry which is "Compare between wireless and wired, which one is more secure?" The answer is wired. It is because wireless send through microwave and no protection, but for wired is send though electric and have protection. Besides that, we know audio can be divide in 2 type which are analog and digital. The process is analog-digital-analog. Quantization error means got noise when played. Lastly, image can be divide in 2 type which are vector (Adobe illustrator) and Raster (Adobe Photoshop).]]> 2018-12-13 13:45:57 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237662 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237783 I really like the lab session every week. We have done the activities through the Quizlet and Socrative and this is the first time for us to use Socrative. It is very interesting. Before end of this lab session, Dr Harry have inform us for the next lab session we will do the quiz by using Socrative as individual and the mark will be calculate as one of our quiz.]]> 2018-12-13 13:46:11 UTC https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237783 ChoiLiTing https://padlet.com/ChoiLiTing/rbmltgoyc8e5/wish/314237979 Today I didn't go to class because I'm not feeling well.
