I learn new tool for quiz game; Socrative. It is fun, challenging question and force us to break the ice with each other in a way to finish the task first in one group. However we found it a bit unfair because latecomers will always answer the question right as we already know which is right or wrong. Chapter 3 Networking Media, and Chapter 4 Wireless Media is an interesting topic but might be challenging for multimedia students to adapt and understand the practical stuffs. After Diploma i got a certificate in Fluke Network in Wireless and Data Communication from KISMEC.

LAN MAN WAN PAN(pan is new). VPN do encrypted connection.
Secure remote access > user devices remotely.
device posture is when device meets certain requirement.

VPN Types : /remote access - securely connects a device outside the corporate office,
/Site to site-connect the corporate office to branch.

Network topologies- shape formed by all the connections joining the various nodes in the network.

Factor influence- physical, distance, operating, existing system, expandability, reliability.

Bandwidth- the range of frequencies embodied in a signal & range of frequencies that a system can process.

Throughput- is how many bits are actually transferred between two computer in a given time

OSI-Open System Interconnection

This is the time we explore the most efficient way to fullfill the need of PnP. Remote learning does not suit everyone in certain way but this is the new normal.

Luckily this class already prepared the way of PnP and the tools itself from the beginning of semester so that the student can adapt it  without much problem.

Currently we already using Edpuzzle, Socrative, Quizizz and Webex(as suggested by the university) and still looking forward to explore more effective features and tools

Common Network Topologies
MESH(full/partially>WAN)

Multimedia Network Communication.

Network suit carrying multimedia element.
-Performance-QoS-Transmission

Network Performance(3 step)
- set of parameters need from network
- what network can provide
- compare both to decide

NPPs - set of parameter to characterize network performance (4 char)
1-Throughput(raw ability-bit rate)
2-NetworkDelay(time taken traverse)
**Packetization(time taken to break)
**Transmission(time take to pass)
**Propagation(time delay from object is injected to receiving)
3-DelayVariance(diff pack diff delay) aka delay jitter
4-ErrorRate(3type)
***Bit error rate(BER)-num of bit corrupt - quality
***Packet/Cell error rate(PER/CER)-num of pack corrupt - lost, duplicated
***Packet/Cell loss rate(PLR/CLR)- num of pac lost -will never arrive

Qos: Parameters
>Performance - delay and bit rate
>Format - resolution, fps, storage
>Sync - skew audio video
>Cost - data charges/fees
>User -  image sound quality

QoS: Perspective
>User - disting diff quality
>Application -  performance app
>Transmission - quality of MNperformance

*HAFAL DIAGRAM*

Multimedia Transmission
-AV most demand MN

req if AV transmission
-realtime / storage
Qualy - Human sense
Quanti - more technical SAS factor in AV

day146 still at uum

New media and business, is a chapter that introduce us to the current progressive development of multimedia tools/product on our daily life. Most of the product aim to enhance UX. currently we already have Social Media, Ar, CSCW for education, entertainment, professional work.

Right now everything still expensive and limited place to find. in the future I hope that this market  really impact in our country. and the society mentality to accept it as a new way of life. especially for the IOT.

As if i can reflex daily life at UUM during this RMCO that are currently using google form(for student) to check in and out at the main gate uum  and for friday prayer, is tedious process. why don't UUMIT just make use of UUM Attendance application and use it suit with the need of security(UK) at uum gate and friday prayer(PI).

while using that google form i can cheat anything i want or anyone else can claim to be student.

my ambition used to be 'white hat' lol.

While studying at KISMEC, one of the subject i take is Hacking. I have experience using several tools, for password hacking, phishing, and eavesdrop through network, it is fun experience.

i wish I am still alive to experience IOT and smart city in Malaysia lol. Is sensory traffic light is consider smart city or at least smart road. because it is useless when people don't know that is a thing at that particular implement location, and they will stop behind the sensory line and the traffic light will stay red forever.  *Experience this at Kulim high tech
