Refers to the process of
conveying a message
(information) from sender to a
receiver through a medium.
Communication
It is the exchange of thoughts,
messages, or information as by
speech, signals, writing or
behavior
Communication
Refers to the process of transmitting electronic
information of any type including television
pictures, sounds, facsimiles and data in the form of
electronic signals or impulses
Telecommunication
The electronic transmission of signals for
communications, including such means as:
Telephone
Radio
Television
Telecommunication
It is the transfer of information from
one computer to another over a
communication link
Data Communication
Refers to the process of sending
digital information (usually in binary
form meaning the message is in the
zeros (0) and ones (1) only) from one
device to another
Data Communication
Is an interconnection of usually passive
electronic components that performs a specific
function to simulate a transmission line or to
perform a mathematical function such as
integration or differentiation
Network
Is the construction, design, and use of network
including the physical (cabling, hub, bridge,
switch, router, and so forth), the selection and
use of telecommunication protocol
NEtworking
computer software for using and managing the
network and the establishment of operation
policies and procedures related to the network
for the purpose of sharing resources
Networking
5 benefits of Networking
Benefits of Networking
1. Resource Sharing
2. High Reliability
3. Efficiency
4. Cost-Effectiveness
5. Access to powerful communication
medium
The main goal of networking is to share resources,
that is, to make all files or data, programs and
equipment available to anyone in the network
regardless of the physical location of the resources
and user.
Resource Sharing
Data loss (e.g. cause by power failure), can be
prevented in networking by replicating data from
one computer to another or having a back-up for
high-reliability is also known as Fault-Tolerance)
High Reliability
Networking is output-driven. It gives you the
advantage of producing the maximum output in
the quickest time possible.
Efficiency
which is one of
the main reasons why most companies are into
networking already, is being “cost-effective”.
Imagine the money that a company can save upon
having a network.
Cost- effectiveness
Having a network in a company also makes
employees produce effective outputs with
minimum time and efforts exerted.
Efficiency
One of the amazing benefits that
networking brought about is being able to
communicate across the world anytime
and almost anywhere
Access to powerful communication Medium
Three Major Types
of Network
Local Area Network (LAN)
Metropolitan Area Network (MAN)
Wide Area Network (WAN)
It is a collection of two or more
computers that are located within a
limited distance of each other and that
are connected to each other, directly or
indirectly.
Local Area Network (LAN)
It is the basic building block of any
computer networks
Local Area Network (LAN)
include some type of
telecommunications components
and activity to handle long-distance
transmissions.
Metropolitan Area Network (MAN)
It is a network with a
maximum range of about 75
kilometers (45 miles) or so, and with
high speed transmission
capabilities.
Metropolitan Area Network
is a network that connects users across large
distances, often crossing the geographical
boundaries of cities or states.
Wide Area Network
It has no geographical limit
Wide Area Network
It can connect computers and other devices on
opposite sides of the world
