In this day, i still not back to UUM because i have some family matters at my hometown.

But, i have contacted my mate on what to do (task) in our first week of MM System Networking class.
So, i have created a new padlet link (https://padlet.com/nashriq3118/paccql0lhdpj) for class purposes just like Dr. Harry ask.

In this case, i am very sorry because i have skipped my class on the very first week.

Today class is Lab class. Dr. Harry ask us to do some group activity that have been assign last week. We have seated with our group members and discuss about Chapter 1 notes which is Introduction of Networking. Platform or application that we use to presenting is MindMeister instead of using Microsoft Powerpoint. MindMeister is a web-based application to create a mind map. So, at the last session of the class all group have to present about mind map that created by using the MindMeister.

Today is a theory class of MM System Networking. Dr. Harry continue his lecture about 2nd chapter which is a bit fun to learn. Dr. Harry explain about the Virtual Private Network (VPN) which is the function is to create encrypted connection over public network. It is also maintain privacy through security procedures and tunneling protocols.

Next, Dr. Harry teach about the network topology which has 5 topology which is Star topology, Bus topology, Ring topology, Mesh topology and Tree topology. Dr. Harry said fully mesh is most relevan and good topology because their nodes and hub used their own connection.

Lastly, Dr. Harry teach us abput the types of computer network, LAN, MAN, WAN and last but not least is PAN. Then, Dr. Harry teach us about the order of that 4 types of computer networks. Diagram below is an order start from WAN to PAN.

Today in the lab class Dr Harry teach us about the OSI Model and the function of all the OSI Model. Basically, OSI has 7 layer which start from Layer 1 until Layer 7. From layer 1 we could see the physical layer which consist of the cabling such as copper cable, fibre optic to interconnects the data. Moving on the layer 2 we have a Data Link layer which it has the hardware which is switch. It interconnects the interner from the server to the host. The OSI Layer continue as per below:

Layer 3: Network (it used to spread the internet connection from the server to the host or user using the device (ROUTER).
Layer 4: Transport (it used to break or compress the data into packets)
Layer 5: Session (establish n terminate the connection)
Layer 6: Presentation (Conversion of the data)
Layer 7: Application (apps and database system)

Next, we have been lecture about the Bandwidth and Throughput. As per Dr. Harry, BANDWITH is the size that user could get but the THROUGHPUT is a actual size tha user can get. It is depend on the factors that influence the connection between the ISP and the user (home, office, school, uni). The factors the could influence the network connection as per below:

Distance

Weather

Area (Urban, Suburban)

Types of data

Types of cable

In this week,the class have been conducted by online that is because of the UUM Learning syllabus to do an online class once. Dr. Harry decided to do some exercise about Chapter 4&5 which is Networking media (copper media) and Networking media (physical layer). We have to complete the task that has been assigned to us using mobile application called EdPuzzle. We have to complete all the answer based on the video (chap 4&5) that Dr. has prepared to us.

Today, the theory class is continue as per normal learning about multimedia info representation. We have learnt about the multimedia element which is text, audio, static image and moving image and they are binary large object (BLOB).

Besides that, we also have learnt the three types of text code which is Morse Code, ASCII and EBCDIC.

Next we discuss about the ADC and DAC in audio. Generally, ADC will change the analog sound to digital form. While DAC will change the digital sound to analog form and this process is call quantization.

Lastly we have going through about static image and moving image. Static image has 2 types which is bitmap form and vector form. Moving image have composite and component and nowadays we all use component.

In this lab class we have covered NSP or Network Security Policy chapter. Basically, I have 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.

The 3 main components of NSP covers:

1. Governing policy

2. Technical policy

3. End-user policy

Last session of the the class we are required to do an activity which every student have to create 10 password policy for university.

On lab class today, we have conducted by some activitusing Quizlet and Socrative. We have to search for our group member based on particular name in the Quizlet and Socrative. In Quizlet, every member in a group will got a same question, but different answers. That required us to discuss a bit and select one correct answer for a question. The fastest group that can answer all question will be the winner. The quizlet is a formative assignment for us
In Socrative, every member in the group will got the same question but in different order. Basically we should answer individually but we can ask our group member. This socrative activity is summative which is the mark will be carry to the exam.

Both activity was fun activity and can make us easy to remember the topic.

Today class the theory class Dr. Harry has teach us about the multimedia data compression. We have learnt about the important of compression in multimedia content. Basically, compression is the parts of multimedia networking which when sender or the data source send information through the network to the receiver (data sink). Dr. Harry explain about why the multimedia element or we called it the BLOB. BLOB (Binary Large Object) is big in size. So, we need to perform a compression and decompression or CODEC to transfer it.

Next, we have learn about the compression categories. The categories are the entropy (lossless) and source (lossless and lossy).

Lastly, we learnt the step of image compression which are:

1. Image preparation
2. Image processing
3. Quantization
4. Entropy coding

Today class Dr. Harry is lecture us as per normal about the M ultimedia Network Communication. 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 consists of 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).
