Networking is defined as connectivity between peers inside
network and outside network.Inside network connectivity in
Networking topology is known as Lan and outside Network
connectivity is called as WAN.Lan Is defined as Local Area
Network between peer systems and Wan is defined as Wide
Area Network between Lan to a Lan in different Location and
this connectivity of lan in different locations is defined
as WAN.Networking is depends on OSI layer which is defined
as OPen System Internetworking.In OSI Layer data is reached
to destination from source passing all the 7 layers of OSI
layer and these 7 layers were on either side of network and
they are defined as

Presentation Layer
Data-link Layer
Network Layer
Transport Layer
Session Layer
Physical Layer
Application Layer

It is connection between two or more computer or devices
through the transmission media for the purpose of
communication and accessing resources is called network and
the whole process is called networking.

LAN,Wi-Fi,WLAN,WAN,VAN,PAN,CAN

Proxy can be defined as an intermediately device,
which plays the role of an agent in the Context of SNMP.It
works as a Virtual LAN to the Devices Which are not having
an Ethernet Inerface,Like MODEMS and Multiplexers.

By using the SNMPPROXY we can Know the STATUS of
these(MODEMS etc) devices.

When an Agent performs PROXY role,it acs on the behalf of
one or more other nodes.A NETWORK MANAGER that wishes ti
obtain the information from or control the node
communicates with the proxy agent.The proxy agent then
translates the MANAGER's request to a form appropriate for
the arget sysem and uses an appropriate nework management
protocol to communicate with the target system.

creating daemon is very simple in Linux. you just need to
create a child process from its parent process and kill the
parent process. also you should close all the I/O streams.
[as daemon is a background process which is not interactive
in nature].

latter on you can write a init script in /etc/init.d/ to
make it a service.

This the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data.
Data Communication is the process of transferring information from a sender to a receiver with the use of a medium in which the communicated information is understood by both sender and receiver. It is a process that allows organisms to exchange information by several methods.

Telecommunications is a general term for a vast array of technologies that send information over distances. Mobile phones, land lines, satellite phones and voice over Internet protocol (VoIP) are all telephony technologies -- just one field of telecommunications. Radio, television and networks are a few more examples of telecommunication.

com port is a communication port or a serial port. which is
used to connect the mouse,keyboard,router and modem.

its cache memory.

A CPU cache is a cache used by the central processing unit
of a computer to reduce the average time to access memory.
The cache is a smaller, faster memory which stores copies of
the data from the most frequently used main memory
locations. As long as most memory accesses are to cached
memory locations, the average latency of memory accesses
will be closer to the cache latency than to the latency of
main memory.

When the processor needs to read from or write to a location
in main memory, it first checks whether a copy of that data
is in the cache. If so, the processor immediately reads from
or writes to the cache, which is much faster than reading
from or writing to main memory.

172.16.8.159 \ 25

172 16 8 159
10101100.00010000.00001000.10011111

8 +8 +8 +1 =25
11111111.11111111.11111111.10000000

Zeros mean, that you can change address bit, so
159=10011111 and last combination of 0011111 is changeable,
so max number in you network usually is broadcast address.
so last byte is 1(unchangeable)1111111(max sequence of
changeable bits).

11111111(bin) means 255(dec)

Whole address 10101100.00010000.00001000.11111111 =
172.16.8.255

Protocols TCP/IP is used to configure windows Operating
System which is abrreviated as Transmission Control
Protocol for transmitting data from one system to another.

Protocols IPX/SPX are used in Unix operating system for
transmitting data.

Protocols ICMP are used as Internet Protocols.

NIC (network interface card or Lan card)

FTP,PPP,IP

It depends on type of windows server
1.Enterprise Edition
2.Standard Edition

In Enterprise Edition more users add

yes

By using VLAN technology we can reduces the size of
broadcast domain.

VLAN (virtual local area network) is a logical grouping or
segmenting the devices under a single broadcast domain.
as a result provides Security and Flexibility.

Defragmentation is smiple says bring the data at once place
in the drive....when we copied or save a file it save on
different sectors on the drive when u browse for the file
it will search every sector id (for every sector we have an
id).when defragmentation done all the data bring upto one
part and it will take less time to reterive the data...

IIS used for Browsing Intranet

Net (all websites):through CCPROXY software

Or

Install windows 2003 server run Domain controller promotions
--> Install DNS server default setting(not Manually)

In LAN system --> Local Area Connetion Status-->In
properties--> Gateway is server IP address and DNS are ISP
dNS(That system added to the windows 2003 server domain)

ccproxy software is easy

An element management system (EMS) manages one or more of a
specific type of network elements (NEs).
Using an EMS a user can manage all the features of each NE
individually, but not the communication between NEs.

Communication between NEs is managed by the network
management system (NMS).

A network management system is a combination of hardware and
software used to monitor and administer a network.

Network management refers to the maintenance and
administration of large scale computer networks at the top
level.

In brief,If network vendor wants to manage multiple
EMS,vendor can go to NMS.

If network vendor wants to manage multiple EMS,vendor can
decide to go for NMS.

If network vendor want to manage one or more of a specific
type of network elements (NEs),vendor can decide to go for EMS.

Management information is viewed as a collection of managed objects information store in a Base is called MIB

first we should RAID card ....which is easly avaivlable in
market conect it on ur mother board . then connect it with
u r hard disk
then before starting the os in a syatem configure ur RAID

just select whatever instruction come in your way...it is
very simple to follow
and finally select ur type of RAID...
