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.

NETWORKING FUNDAMENTALS II

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

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)
BUS
RING(MAN/WAN)
STAR
HYBRID

Common Network Type

OSI Reference Model

Upper layer data
-Application (Mail Web FileTransfer)
-Presentation(ASCII)
- Session(Control dialog)

Segment
-Transport(TCP and UDP)

Packet
-Network(provide connection between host diff network)

Frame
-Data Link(provide connection between host same network)

Bits
-Physical(electrical/devices)

Multimedia Data Compression

Data Redundancy - amount of repeated data - waste of space

Interpixel redundancy
Psycho-visual
Data source - data from sender
Data sink - data received
Compressor/Coder - reduce volume of data
Expander/Decoder - regenerate data compress

Categories - Entropy/Source

Techniques
-Repetitive sequence
- Statistical
- Vector Quantization

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

Type of attackers
1. Hackers - attacking system for protest, challenge, enjoyment or to evaluate weakness
2. Criminals attack for benefit - stealing credit card num, trade sec
3. Cyberterrorism INFORMATION WARFARE / cyberwar
4. Employees - dishonest emp, former emp, exp: theft fraud, sabotage
Type of Attack

Malicious - virus, worm, torjan, spam
DenialOf Service - suspended your access
Scanning Attack - to scan user IP address

Type of Security System

Secure communication system - protect message communication between two parties from eavesdroppers / capture
Attack prevention system - stop attackers from hacking, use firewall
Network Security Policy - a document of rules for user, admin, req system

Security System

Confidentiality - access by authorized people
Integrity - req modification data only by authorized people
Availability - req data only available to authorize people
Authenticity req host or service be able to verify the identity of user

Attack prevention System
to stop incoming message

Firelwall - guard gate between network
Network address translation (NAT) - method of remapping IP add, hide from sniffer.
Instrussion Detection - device/software app that moniteor network or system to identify malicious attack.
Access Permission - limiting access to particular folder file, login system,

Encryption for confidentially
compression / decompression
encryption / decryption
- protect data
- facilitate secret communication
Authentication
process to determine to authenticate access

Password a.Text easy use, difficult to remember, predictable b.Graphical hack tech dictionary attack
Digital signatures - algorithm scheme verify DS.
Biometric - authentication based on personal features a.fingerprint b.iris c.face recognition
Smart Card - pocked size digital authentication

Digital Certification
an electronic document to prove ownership of public key by applicant.

MicroNugget: Using Quality of Service (QoS) Tools

Classification, - identify and priorities the specific traffic.
Marking - optional phase, to tag identified traffic, allowed CoS(sw), ToS(rt).
Policing - anti-QoS, kind of regulation. allow to set limit.
Shaping - allow to hold and queuing traffic
Congestion Avoidance - allow to stop congestion but slow it down.
Queuing - priority queuing by important traffic.

day^{146 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
