ST-Strait Tips
Fiber Obtic Cables are The latest development in cabling Technology They Are Constructed From obtical Glasses.There is central glass filament calied the core and surrounding layers of cladding
buffer coating strengthening materials and outer jacket
information is transmitted by wavelength of light This is accomplishrd through devices that convent electrical signal into repiod pulses of either LED Laser Light Fiber obtic Cables After several advantage including
1.High Bandwidth capacity (many gigabite per second)
2.Longer Distance Between Device (from 2 t0 over 60 km)
3. immunity to electromegnatic interferences
Fiber obtic Cables are widely Used in WAN for both Voice and Data communications. The primary barrier to their widespread use in LAN is the Cost of electronic

OSI MODEL
1.researced and developed by the ISO- (INTER ORANIZITION FOR STANDARDIZATIONS)
2.1977 establish a subcommit to develope a communition architecture
3.1984 publish iso 7498 the open system interconnection osi reference model
THE OSI MODEL A FRAME WORK WITHIN WHICH NETWORKING STANDARDS CAN BE DEVELOPED IT PROVIDED VENDORS WITH A SET A STANDARDS THAT ENSURED GREATER COMPABILTIY
AND BETWEEN THE VARIOUS TYPES OF NETWORK TECHNOLOGIES THAT WERE PRODECER BY THE MANY COMPANIES AROUND THE WORLD
Q-WHY A LAYERED MODEL ?
+reduce complexity
+ standardizes interfaces
+ facilitates modular engineering
+ensure interoperable technology
+ accelerates evolation
+simplifies teachning and learning
What is internet,interanet,extranet?
INTERNET
1.internet is a network of network a network to be called as internet any unknown external user or user or users are allowed to access the part of resources of the network.
2.when you want to expose information to everyone in the world then we use internet protocol such as HTTP,FTP,SMTP, it is a example of internet
INTRANET
1.an intranet is a private N/w
2.it can be a collection of LAN ,MAN,&WAN
3.users access the resources from with in the oraganzition (locally)
4.if it within company's intranet the information
would not be access ible to person on the internet
it is for private use only
EXTRANET
1.extranet is a extended intranet
2.some service are made available to known users or bussiness partner
3.they can access resource from outside the organization (remotely) like home or office
4.in intranet users access the resources from within the organization while in a extranet some known users are allowed to access the resources from the outsides network
5.if we have a web based application that allows selected outside bussness partners to review their accounts that is called extranets

What is a network topology?
ans- In communication networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.
The physical topology of a network is the actual geometric layout of workstations. There are several common physical topologies, as described below and as shown in the illustratio
MAN(metropolitan area netework)-
it is a N/w which is located with a signal geagraphical region area
man usually do not use private dedicated
CAN(campus area network)-
it is located in a collage campus or two or more building having a same office in a limited area
SAN(storage area network)-
A storage
area network (SAN) is a dedicated network
that provides access to consolidated, block
level data storage. SANs are primarily used to
enhance storage devices, such as disk
arrays, tape libraries, and optical jukeboxes,
accessible to servers so that the devices
appear like locally attached `devices to
the operating system.
PAN (personal area network)-A personal
area network (PAN) is a computer
network used for data transmission
among devices such
. PANs can be used for communication
among the personal devices themselves
(intrapersonal communication), or for
connecting to a higher level network and
the Internet

LAN(Local area network)-A local area network (LAN)
is a computer network that
interconnects computers within a limited area
such as a residence, school, laboratory, or
office building
WAN(wide area network)-A wide area network (WAN) is a telecommunications network or computer network that extends over a large geographical distance. Wide area networks often are established with leased telecommunication circuits.

Business, education and government entities use wide area networks to relay data among staff, students, clients, buyers, and suppliers from various geographical locations. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet may be considered a WAN
