What is router?
Router is a device that is used to connect two different networks.
How will you configure ADS?
Start ==> Run ==> DCPROMO
Or
Start==> Configure your server ==> add/Remove a Role
Or
Start==> Configure your server ==> add/Remove a Role
What is ADS?
A central component of the Windows platform, Active Directory service
provides the means to manage the identities and relationships that make up
network environments.
What if this wizard (ADS) is not running?
Check the network cable it
should be plugged
Check root partition it should be in NTFS
Check IP of server it should be configured statically

Check IP of server it should be configured statically
How will you add a client to server? /
How’s the client join a domain?
What are the client configurations?
On Server
Configure ADS (for example it’s configured with xyz.com)
On Client
Log in form local administrator account
My Computer ==> Properties ==> Computer Name ==> Change
==>Domain ==>xyz.com ==> username Administrator (of xyz.com)
Password xxxxxxxxxxx (of admin of xyz.com)
Welcome to xyz.com ==> Restart the computer
Configure ADS (for example it’s configured with xyz.com)
On Client
Log in form local administrator account
My Computer ==> Properties ==> Computer Name ==> Change
==>Domain ==>xyz.com ==> username Administrator (of xyz.com)
Password xxxxxxxxxxx (of admin of xyz.com)
Welcome to xyz.com ==> Restart the computer
Does it necessary to use administrator account to configure the client?
Not every time but you are required a properly configured user account in
domain controller security policy.
ISO stand for?
International standard organization
OSI stand for?
Open System Interconnection
What is full form DHCP and how will you configure it?
Dynamic host configuration protocol
To configure it on Server
Configure your server ==>Add/Remove a role ==>DHCP server ==>complete the wizard
Start ==> Administrative tools ==> DHCP ==>New scope ==> Wizard
Now authorized this server and do activate it
On client
Local area network ==> tcp/ip ==> obtain ip automatically
Obtain DNS automatically
To configure it on Server

Start ==> Administrative tools ==> DHCP ==>New scope ==> Wizard
Now authorized this server and do activate it

Local area network ==> tcp/ip ==> obtain ip automatically
Obtain DNS automatically
Which OSI layer does IP belong?
P belongs to the Network Layer (layer 3) in the OSI model.
What is a subnet mask?
Subnet mask is a 4 byte (32 bit) number used to identify the sub-network ID
and the host ID from an IP address. All the hosts in a sub-network will have
the same subnet mask. E.g. 255.255.255.0, 255.255.127.0, 255.255.0.0
Why do we do networking?
For data sharing
To accumulate hardware resource

What are the benefits of networking?
There are lots of advantages from build up a network, but the three big
facts are-
File Sharing
From sharing files you can view, modify, and copy files stored on a different computer on the network just as easily as if they were stored on your computer.
Resource Sharing
Resources such as printers, fax machines, Storage Devices (HDD, FDD and CD Drives), Webcam, Scanners, Modem and many more devices can be shared.
Program Sharing
Just as you can share files on a network, you can often also share program on a network. For example, if you have the right type of software license, you can have a shared copy of Microsoft Office, or some other program, and keep it on the network server, from where it is also run

What is network?
A network is basically all of the components (hardware and software) involved in connecting computers across
small and large distances.
What is networking?
A process that is describes how the network will connect.
What is meshing?
Meshing generically describes how devices are connected together. It
is also the part of topology. There are two types of meshed topologies: partial
and full.
In a partially meshed environment , every device is not connected to every other device.
In a fully meshed environment, every device is connected to every other device.
Wireless is the good example of meshing. Wan ( internet is also a good example of meshing where a computer have connectivity with all internet network.)

Describe Various Network Type
Local Area Networks Local area networks (LANs) are used to connect
networking devices that are in a very close geographic area, such as a floor of
a building, a building itself, or a campus environment.
Wide Area Networks Wide area networks
(WANs) are used to connect LANs together. Typically, WANs are used when the
LANs that must be connected are separated by a large distance.
Metropolitan Area Networks A metropolitan area network (MAN) is a
hybrid between a LAN and a WAN.
Content Networks Content networks (CNs) were developed to ease users’
access to Internet resources. Companies deploy basically two types of CNs:
1.Caching downloaded Internet information
2.Distributing Internet traffic loads across multiple servers

2.Distributing Internet traffic loads across multiple servers
Storage Area Networks Storage area networks (SANs) provide a
high-speed infrastructure to move data between storage devices and file
servers.
Advantage
Performance is fast.
Availability is high because of the redundancy features available.
Distances can span up to 10 kilometers.
Management is easy because of the centralization of data resources.
Overhead is low (uses a thin protocol).
Disadvantage of SANs is their cost.

Intranet An intranet is basically a network that is local to a
company. In other words, users from within this company can find all of their
resources without having to go outside of the company. An intranet can include
LANs, private WANs and MANs,
Extranet An extranet is an extended intranet, where certain internal
services are made available to known external users or external business
partners at remote locations.
Internet An internet is used when unknown external users need to
access internal resources in your network. In other words, your company might
have a web site that sells various products, and you want any external user to
be able to access this service.
VPN A virtual private network (VPN) is a special type of secured
network. A VPN is used to provide a secure connection across a public network,
such as an internet. Extranets typically use a VPN to provide a secure
connection between a company and its known external users or offices. Authentication
is provided to validate the identities of the two peers. Confidentiality
provides encryption of the data to keep it private from prying eyes. Integrity
is used to ensure that the data sent between the two devices or sites has not
been tampered with.
