Network transmission media
Types of networks based on physical scope
Network Classification
Network transmission media
A. There are four connection methods for transmission media:
1. Optical fiber: An optical fiber is used for communication in a single direction. STC
uses the optical fiber when transmitting telephone.
2. Wired: waves are guided along a solid medium such as a transmission line. STC
offered wired services like the telephone services.
3. Wireless: transmission and reception are achieved by means of an antenna. STC
offered wireless services like broadband services and internet.
4. Point-to-point laser: Laser communication follows line-of-sight, and requires a clear,
unobstructed path between the communicating sites(the sending and receiving
equipment must be united precisely to insure that the sender's beam hits the sensor in
the receiver). STC uses the point-to-point laser in order to make sure if the data are sent
or received.
B. Wired technologies:
 Twisted pair: The use of two wires twisted together helps to reduce crosstalk and
electromagnetic induction. While twisted-pair cable is used by older telephone networks
and is the least expensive type of local-area network (LAN) cable, Twisted pair is the
ordinary copper wire that connects home and many business computers to the telephone
 Coaxial cable: has a wire conductor in the centre, a circumferential outer conductor, and
an insulating medium called the dielectric, separating these two conductors.
 Optical fiber: Telephone transmission method uses fibre-optic cables. Optical fibres
transmit energy in the form of light pulses. The technology is similar to that of the coaxial
cable, except that the optical fibres can handle tens of thousands of conversations
C. wireless technologies:
 Terrestrial: Communication uses equipment such as radio or microwave transmitters that
is relatively close to the earth's surface. STC has a lot of man made towers for
telecommunication services. Actually, it sells the bad towers to Mobily Company; that is
the reason behind having a bad network for those who use Mobily sim cards or internet.
 Satellites: communications satellites provide a microwave radio relay technology
complementary to that of communication cables. STC use it for mobile applications such
as communications to ships.
 Wireless LANs: STC serves many wireless LANs services or Wi-Fi devices that are used
for many needs such as connecting laptop users who travel from location to location, and
mobile networks that connect via satellite.
Types of networks based on physical scope
Local area network
A. (VPLS) services:
STC provides (VPLS) services as network's default, so they provide this service to concept of
Virtual Private Network to enable the clients business to link set of points to others customers
form other places through the use of Layer 2 over STC’s Multiprotocol Label Switching (MPLS)
network. VPLS Bandwidth Offering From 2 Mbps up to 2.5 Gbps.
So we can use this service in various government and private sectors, such as Financial
applications, data Centers interconnectivity, stock market, network-Based meeting, like banks,
health sector, Education, transportation, and other business sectors, because this service check
the demands of the business sector.
B.Service Benefits:
1.High Availability
VPLS through VPN provides “Any-to-Any” connectivity over Ethernet. Therefore, all the
corporate sites appear to be on the same LAN, regardless of their location.
2.High Flexibility
VPLS allows business to use any routing protocol.
3.High Efficiency
VPLS enables business communications to be transported via non-IP protocols. Additionally,
VPLS enhances businesses through offering broadcast and multicast applications.
Personal area network
STC company used A personal area network (PAN) is a computer network used for
communication among computer and different information technological devices close to one
person. Like
 printers.
 fax machines
 telephones
 scanners
Also PAN may include wired and wireless devices.
A.A wired PAN :
is usually constructed with USB and Firewire connections
B.A wireless PAN:
1. such as Bluetooth .
2.infrared communication.
Home area network
STC used A home area network (HAN) is a residential LAN which is used for communication
between digital devices typically deployed in the Company, usually a small number of personal
computers and accessories, such as printers and mobile computing devices. An important
function is the sharing of Internet access, often a broadband service through a cable TV or
Digital Subscriber Line (DSL) provider.
Also STC offered :
A.DSL Sky Internet:
Sky Internet Protocol (IP) allows you to leverage the coverage of satellite to expand the IP-VPN
coverage, which enables you to have IP-VPN at all locations, regardless of distance.
*Service Benefits
High Availability
DSL sky internet provides connectivity anywhere throughout the Kingdom, regardless of the
existence of a terrestrial service.
High Scalability
DSL sky iInternet offers you higher upstream and downstream bit rates, where it works
independently from the existing terrestrial infrastructure.
Easy and Fast Setup
Sky IP is an easy and fast technology to setup, which can be fully deployed within 1-2 days
Wide area network
A wide area network (WAN) is a computer network that covers a large geographic area such as a
city and country even intercontinental distances, using a communications channel that combines
many types of media such as telephone lines, and cables. A WAN often uses transmission
facilities provided by common carriers, such as telephone companies. WAN technologies
generally function at the lower three layers of the OSI reference model: the physical layer, the
data link layer, and the network layer.
STC support this service by using Aamal Net , this services provides a comprehensive business
management internet package (basic package) which includes ADSL connectivity and
professional router with service remote management to meet your different business needs.

Campus network
A campus area network (CAN) is a computer network made up of an interconnection of LANs
within a limited geographical area. The networking equipment (switches, routers) and
transmission media (optical fiber, copper plant, Cat5 cabling etc.) are almost entirely owned by
the STC campus
In the case of a STC campus-based campus network, the network is likely to link a variety of
campus buildings including, for example, head offices or any departments.
Metropolitan area network
STC building used Metropolitan area network (MAN) to keep and control their informations.
Also STC provide this services to the government and huge company because MAN is a large
computer network that usually spans a city or a large campus, it's not cheep at all.
Enterprise private network
STC used An enterprise private network to built network by an enterprise to interconnect
various such as company sites, head offices and remote offices, in order to share computer
Virtual private network
STC offering VPN to the country because it can be used to separate the traffic of different user
communities over an underlying network with strong security features. So a VPN has a topology
more complex than point-to-point.

Overlay network
For example, many peer-to-peer networks are overlay networks because they are organized as
nodes of a virtual system of links run on top of the Internet. The Internet was initially built as an
overlay on the telephone network.
Network Classification
Network architecture:
Network architecture is the design of a communications network.
1. Active networking: It consists of active hardware, capable of routing or
switching as well as executing code within active packets.
2. Client-server: A network architecture in which each computer or process on
the network is either a client or a server. Servers are powerful computers or
processes dedicated to managing disk drives (file servers), printers (print
servers), or network traffic (networkservers ). Clients are PCs or workstations
on which users run applications. Clients rely on servers for resources, such as
files, devices, and even processing power.
3. Peer-to-peer: computers are dedicated to serving the others.STC this kind of
networking in sharing files without the need central server.
Network topology:
A topology refers to the manner in which the cable is run to individual workstations on
the network.
1. Ring topology: arranges for computers to be connected in a closed loop
2. Mesh topology: provides a direct connection between each pair of computers
3. Star topology: all computers attach to a central point
4. Bus topology: usually consists of a single cable to which computers attach.
