How the Internet and Email Work

The document provides a summary of how information is processed and transmitted over the internet. It explains that when a link is clicked, a package of information is sent with the sender's address, receiver's address, and packet type. The package first travels to the local area network and then the router, which routes packets between networks. It then goes to the proxy server, which checks the URL safety before sending it to the internet. The package passes through firewalls that prevent unwanted data and leaks. It is received by routers or switches that transfer data through bandwidth. Not all packets are acknowledged, and unacknowledged packets are replaced. The package then travels through the worldwide web to its destination, going through firewall scanning at the receiving end

REACTION PAPER

The dawn of the net is a very informative and creative way of showing how the internet
and email works, sa video nagpapakita kung paano pinoprocess ng internet ang information
natin. it shows what will happen kapag klinick natin ang isang link at sinasabi dun every
package of information have its own corresponding size depende kung anong website, every
package ay naglalaman ng ibat ibang information senders address, receivers address at kung
anong packet ang ginamit. Pinapakita kita din doon na after sending sending the package after
pressing the enter button it will travel to the LAN o local area network, ang LAN daw ay
ginagamit para maconnect ang local computer at router, printer, etc. and after going through to
LAN it will send to the Router. And router is used to transfer data from one network to another
using router switch, sa video dinidiscribe si router switch as a digital pinball wizard because it
routes the ip pockets fast and loose to its designated way. After naman dumaan kay router
switch dadalhin naman sila sa proxy na ginagamit para mag send ng data sa internet, after
icheck ni proxy yung url at kung safe ba ito the package will go to the internet. Kapag nandun na
siya sa destination niya dadaan naman yung package sa firewall, the corporate firewall serves
two purposes according to the video, una ay it prevents nasty things or unsecured data or things
coming to the internet into the intranet at pangalawa ay para maprevent niya ang leak ng
sensitive information to the internet. After going through the firewall another, router or switch
receives the package to many designated narrow roads or what we call bandwidth which ang
purpose ay mag transfer ng data from one place to another. But not all packets cannot continue
on the path, kapag di na acknowledge ni IP yung isang packet ay irereplace niya yung packet
nayun o papalitan. And after that, the package will go through the internet o world wide web, it
describe the world wide web as a spider web that connects with many links and a free space to
go with many opportunities. And after traveling to the designated destination along the way the
package will go through the another firewall. Sa firewall nayun makakalagpas kalang kung meet
mo yung criteria nila kadalasang ginagamit na port dito ay 80 at 25 and the other ports are used
in business. Ang port 25 ay ginagamit para sa mga mail packets and port 80 is the the entrance
for packets from the internet to the web server. At saloob daw ng firewall every packaged are
screened thoroughly. After going in firewall the packaged lineup on the interface para mapunta
sa mga web server, isa isa nirereceived ang mga package at binubuksan st psgkstspod mskuhs
yung information at isend sa web server the packaged will be recycled at pwede ulet gamitin
para lagyan ng bagong data o information the packaged will send back to you and go through
the same process and that's how the internet and email sent and received.
