Unfortunately, I cannot come to the class because I am still in Kuala Lumpur since I did not get the bus to UUM the night before.]]> 2018-09-13 13:31:40 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/280817887 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/280822927 Today is the first day I come to the class. Today Mr Harryizman told us to download and install 3 applications, such as Padlet, Quizlet, and HP Reveal and taught us how to use those applications. The class today finished early, we finished at 2PM even though in the timetable, our class finished at 2.30PM.]]> 2018-09-13 13:39:23 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/280822927 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/282694319 Today Mr Harryizman explains about Chapter 1: Introduction to Networking. We learned about the definition of network itself, and how important is the computer network. We also knew the different types of network, such as internet, telcos, company network, universal network, and home network. Each of those types of network have some different characteristics.

Despite of that, Mr Harryizman explains about the definition of Standard, why we should use standard, and popular networks standard organization.
In the end of class, we were asked to form a group consists of 5 members. And our class finished at 1.45 pm.]]> 2018-09-18 04:29:13 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/282694319 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/284606134 Today, Mr Harry asked us to do revision for Chapter 1: Introduction to Networking. 

He gave us 30 minutes to read the chapter and discuss with our friends. Then, we made a group by using Quizlet, and do some kind of quiz in groups. We are given some question, and we should do in groups because the answer is only in one person per question. When we are correct, we proceed to the next question, but if we are wrong, we should redo the question from the beginning. A group win this game when it finish all the questions first.

We change the group 3 times, and one of my group win this quiz. It is really fun, and make me understand more about the topic.

After do quiz in group, Mr. Harry asked us to do the test in Quizlet. And on the first test I got 83%. Because it is really fun, I retake the test until I get 100%.

That's all.]]> 2018-09-22 08:38:21 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/284606134 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/284607223 Name: Afifah Widadri Rejiana
Matric: 244018]]> 2018-09-22 08:53:24 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/284607223 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/285330934 Today Mr Harry explains about Chapter 2.

Firstly, He explains about the history of computer, and told us that Apple is the first company that produce computer. Also, he told us that the reason why people keep buying Apple products even though it is expensive, is the security of Apple's product is very high and cannot be attacked by virus. Microsoft product is usually attacked by virus because many of Microsoft programs use .exe extension meanwhile it is the extension of computer virus. In apple, the extension of .exe program is .dmg. So it means that if there is .exe program in Apple, it is most likely a computer virus and we can delete it directly.

We also re-study about the network standard organization and why we should use standard. Then, we differentiate 3 components, such as  hardware, media, and software. We also knew what is 'host'.

Then he explains the difference of LAN, WAN, MAN and Internetworks. He also explains about Intranet and VPN.

Next, we discuss what is the network topology and 5 types of network topology with our group members, and each of our members should draw the topology on the whiteboard. My group should have draw mesh topology, but suddenly Mr Harry told us to do star topology. And we finally can differentiate between those topologies.

And class is dismissed.]]> 2018-09-25 04:39:11 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/285330934 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/287059126 Today Mr Harry continue explains about Chapter 2.

First, He explains the difference between Bandwidth and Throughput. Bandwidth is the speed of the network that you buy, and throughput is the actual speed of the network (usually it is less than bandwidth). There are many factors that can make bandwidth become throughput, such as area, cable quality, weather, number of users and shape of the topology.

He also explains about OSI layer model. OSI stands for Open System Interconnection, means any system can use this. OSI has 7 layers, and it starts with layer 7. Mr Harry explains the layers one by one, and make the analogy with pizza delivery, and I become more understand because of it.

Then, he also explains about TCP/IP model. The steps is similar to OSI, but it has less layers than OSI.

In the end of the class, he explains about our second assignment. And told us to download and install an application called Socrative.

That’s all for today.]]> 2018-09-28 17:10:22 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/287059126 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028420 Today we have online class on Edpuzzle. We have to watch videos about 'Networking Media' and do answer some questions. I learned about OSI Physical layer, and 3 types of networking media such as Copper Media, Fiber Optic Media, and Wireless Media.]]> 2018-10-12 05:00:22 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028420 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028438 Today we have online quiz on UUM online learning. The topic covered on this quiz is networking media that we have learned in previous class on Edpuzzle.]]> 2018-10-12 05:00:37 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028438 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028466 Finally, today we do a physical class. 

In the beginning of the class, Mr Harry told us to bring 3 images (printed and soft-copy)based on networking media (which we have learned last week) that represent copper, fiber optic and wireless media for next lab session (Thursday, October 11th, 2018). We also have to bring soft-copy of 3 videos based on those medias.
And Mr Harry told us that we cannot have same images and videos with other groups, so we should told them which images and videos we want to take in our WhatsApp group.

Then. Mr Harry explained new chapter, Network Security Policy. The purpose of security policy is to inform users, staff & manager, specify mechanisms for security, and provide baseline. It continuously updated as technology and employee requirements change and in the form of document.
There are 2 audience of network security policy, such as internal and external audience.
Network security policy has 3 components, such as governing policy, end-user policy, and technical policy. Mr Harry explained us what are the example of those components.]]> 2018-10-12 05:01:08 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028466 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028490 For today's lab, we have bring our 3 images and videos, and we make an aura by HP Reveal application.

Mr Harry told us to sit in groups and develop this aura in PC. The steps are quite simple. First, we log in with the same username and password. Then, we just create a new aura, upload the image and upload the video as an overlay. After finished, once we scan the picture, the video we have uploaded will be appear. Mr Harry told us this is an Augmented Reality (AR)

In the first time, I can not scan the picture, and only one of my group mate can scan it. Mr Harry told us there are some factors why we cannot scan it, such as weak connection and we did not log in to the same username and password. I have log in to the same username and password, so I think the weak connection is the factor I cannot scan. So when I disconnect the WiFi and use my own data, I can scan it.

We also try to make 2 more auras on mmnet, and make 1 more aura on our own username. We also try to scan the auras of other groups.

And after that, the class is dismissed.]]> 2018-10-12 05:01:27 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/292028490 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/297852442 Today, we only have an online class in Edpuzzle.
We have to watch a slide video for ‘Network Security’ Chapter and answer some questions based on the slide. I learned about the purpose of network security itself, and three components of network security: Governing policy, Technical policy and End-User policy. I also learned about the security policy roles & responsibilities, and the security awareness.

In multimedia network, there are 4 elements: text, audio, still image and moving image. Text can be code and decode. To code text, we can use International Morse Code, ASCII and EBCDIC. For audio, there are 2 types of audio: Analog and Digital. Still images has two types: Vector image and Rasterscan (Bitmap) image. And last, moving image has two types: Video and Animation.]]> 2018-12-01 09:40:29 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/310042966 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/310043631 Today, our class is in the lab 02. We have activity in the lab using Quizlet.live and Socrative.
This activity is fun, though. We have to search for our group member based on animal's name (in the Quizlet.live) and colours (Socrative). In Quizlet.live, every member in a group will got a same question, but different answers. So we need to discuss and select one answer for one question. The fastest group that can answer all question will be the winner.
In Socrative, every member in the group will be got a same question but in different order. Basically we should answer individually but we can ask our group member.]]> 2018-12-01 09:50:30 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/310043631 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/310044460 Today, unfortunately I didn't come to class because this morning I just reached UUM from KL.

There are 3 aspects of Multimedia Network Communication: Network Performance, Quality of Service and Multimedia Transmission. Network Performance decides if a network can carry multimedia traffic or not and have 4 parameters (throughput, networking delay, delay variance and error rate). Quality of Service also have 5 parameters (performance-oriented, format-oriented, synchronization-oriented, cost-oriented and user-oriented).]]> 2018-12-01 10:04:25 UTC https://padlet.com/afifahwidadri/stiv3023_reflection/wish/310044583 afifahwidadri https://padlet.com/afifahwidadri/stiv3023_reflection/wish/310044592 There is no class today.
