In this week, I've learned
about basic networking concepts; networking communication mediums and types of
network. There are some advantages of a computer network that i have leaned.
1/resource sharing
(hardware and software)
2/information sharing(it
is easy to access from anywhere)
3/promote communication
and collaboration(email and message )
We have 3 concepts when
every computer functions : topology, protocol, architecture. In addition,
computer network has 3 elements (at least) must exist:
sender->medium->receiver. After this week, i have known more about
wireless networking (wi fi). What's wireless networking?how many types of
network? Before, i just used Wi-fi. I never knew how many types of network?
which one i used? So, there are 3 types of network.
1. Network in small
geographical area is called LAN ( Local Area Network). It usually connected
using Ethernet. There are 2 types of LAN: Intranet, Extranet.
2. Network in a city is
called MAN ( Metropolitan Area Network).
3. Network spread
geographically is called WAN ( Wide Area Network).
This knowledge is more useful for me to use and
connect the wireless anywhere. i can know how to chose which one is better for
me to use. This parts was quite easy to understand. i could knew more what are
the characteristics or peer to peer and server-based network.
