Basic networking concepts
This
week, we will learn about basic of networking. To get connection or network the
first thing that we should have is computer. That why people call that as a
computer network. With networking we can share resources and information and
also can promote communication and collaboration. Topology, protocol and architecture is functions of networking
that can be seen today. Just like Mr. Azam said, if we want communicate we must
have centre or MEDIUM between sender and
receiver. That why communication
is one of the important things for nowadays, because computer and networking as
a centre for people. For data transmission, bandwidth,
analog and digital (type of signal) and serial and parallel (order of bits) is examples for that.
Medium also can be as physical cable. Because twisted-pair cable, coaxial cable, fiber-optic cable and ISDN
line are cable can connect from
sender and receiver. ISDN line we can see it every day because it is special
digital telephone that transmits and receives information from our house. And for
microwave and satellite systems and also cellular and infrared technology known
as wireless media.
Next
is example for network that we used today. There are many examples, Local Area network (LAN) – intranet & entranet, Metropolitan area network (MAN) this between campus and campus and Wide area network (WAN) this network used for network between broad area. Peer-to-peer
networking and server-based networks is connection between software and another
software like computer, printer and so on. So, even tough, I don’t really
understand what I understand from this topic, at least I tries to understand
that :)
