1. What
is network?
Network
is a group of computers, peripherals, and software that are connected to each
other and can be used together.
Network
Models
-Peer to
peer network: computer can share resources with each other, and machines that
share resources can also be used as client workstations.
-Server-based
Network (Client/Server): the roles of each computer in a client/server network
are distinctive. Affection both the hardware used in each computer and the
software installed in each computer.
Server
A server
Is a computer on the network that provides other computers (called clients or
workstations) with access to resources. Because these resources can be used by
different computers over the network, they are called shared resources.
Severs
typically have powerful hardware features than typical PCs, such as SCSI or
SATA RAID arrays or network attached storing for hard disk storage,
Client
-A
Client is a computer that uses the resources on a server. Typical examples of client
computer include windows visa, xp, and 2018, depending on the windows operating
system in use.
One of
the best reasons to create a network of any size is provide access to the
internet.
Network
Protocols
-TCP/IP: Transport control protocol/ internet protocol,
it is a protocol used for both internet access and for local
-NetBEUI/NetBIOS: Extend user interface is an enhanced
version of an early network protocol called NetBios, and NetBeui was
used primarily on peer network using windows with direct cable connection between
two computer.
-Although most current network are based on TCP/IP you
might encounter other in some network. Protocols makes network configuration
easier became users need to configure only one protocol to communicate with
other network client and server.
The following section discuss some of application
protocols that are part of the TCP/IP suite, as well as some of the services
and technologies that relate to.
DNS
DNS the domain
name system is the name for the network of servers on the internet that
translate domain name, such as www.konkhmer7hd.com.
If you manually configure ip address of one or more dns server as part of the
configuration process. Other popular domain name extension include .net .org
.gov .us .kh .cc .
Some browsers will add the www. Prefix use on most
domain name.
