ICA: Router, Switch and hub

   Router > switch > hub. with this you can easily understand what and how do they preform and act as. 
  A hub is like a dumb multiple power where the bandwidth is shared and all its port doesn't have a address of its own thus it cannot track which signal are from which device as the hub itself is identified as a single address.

  Where by a switch is more advanced than a hub as each of its port has its own address and have its own bandwidth without sharing the bandwidth with the other computer connected to the same switch.

  Router is the most advanced of these three and are usually connected to a WAN aka the internet through a cable modem or ADSL modem or any other ISP , it has DHCP, NAT and other advance function such as QoS, Firewall and etc. Some router even have wireless capability thus the name WiFI router, which broadcast the signal to connect eve more devices wirelessly.

Network Topology and Transmission media

  Network topology is the layout of a network, as a network of computer consists of the server, client or server/client. The image below shows the possible configuration and types of network topology.

  Transmission media consists of physical transmission media and wireless transmission media. Example of physical transmission media are optic fiber cable, ethernet cable, coaxial cable, copper wire etc. Where else wireless transmission media are WiFi, WiMAX, LTE GSM, GPRS, GPRS, EDGE. HSPA, 3G etc.

ICA: Mashup

  Mashup is a combination of several web app feature and turning into a new one. A mashup or a mix of website.

ICA: NSFnet

  NSFNET is what came before the internet, one of the network such as ARPANET that shapes the internet we know today. According to Wikipedia what is NSFNET:


The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) beginning in 1985 to promote advanced research and education networking in the United States. NSFNET was also the name given to several nationwide backbone networks that were constructed to support NSF's networking initiatives from 1985-1995. Initially created to link researchers to the nation's NSF-funded supercomputing centers, through further public funding and private industry partnerships it developed into a major part of the internet backbone.

ICA: Silver Ant Trip

  It was a pretty amazing trip as I could get into the insight of the 3D animation industry. I didn't knew that a Malaysia company is involve in the in-game cinematic of several popular game such as Mario, Metroid Prime and Castlevania. I'm impressed and proud in the same time, a Malaysian company are capable of such feat. It totally catches my attention of such potential in m'sia local animation scene. Silver Ant first full length 3D animation SeeFood is pretty interesting and the award winning Saladin is pretty cool too.
