Transcript internet protocol

1) Radio frequency identification.
2) Get it from any device and always there for if you need it.
3) Could be a bad connection, could loose it if host shuts it
down and the software
4) A computer system that relies on technology
5) In supermarkets

• It is a worldwide computer network that uses
protocols to transmit and exchange data.
• NETWORK is an arrangement of intersecting
horizontal and vertical lines that is capable of
sharing information.
• PROTACOL is a set of rules that allows computer
systems to connect with another computer.
• The File Transfer Protocol (FTP) is a standard network
protocol used to transfer computer files from one host to
another host over a TCP-based network, such as the Internet.
FTP is built on a client-server architecture and uses separate
control and data connections between the client and the server.
• Access point to the internet
• Location that has all the hardware to allow users access to the
internet
• ISP’s may use a number of Pop's in an area to allow good
access to the internet
•
•
An interchange between networks within the internet
ISP’s can connect with each other
•
Protocol used to route packets of information across the internet
The protocol that takes the data from the application and passes
it to the IP for transfer across the internet
• The reverse happens on the other end where the TCP will
reassemble the date.
•
•
•
•
ISP’s provide the gateway for the people to connect to the
internet
Examples:- sky, BT, AOL, PlusNet, TalkTalk.
ISP’s commonly provide other services such as TV & phone
packages and a user specific email address.

•
Connecting backbone:- main connecting routes between large
networks and local networks
Server:- computer/program that runs the needs of connected
computer
Router:- directs the data packages to the correct
destination/device
Client:- computer that uses the services provided by the server.

Mobility
 Access to real-time information.
 Supports productivity.
 Provides service opportunities.

Promotes flexibility. Scalability
 Patterns are easily changed.
 Works over great distances.
 Effective for wide range of user communities.

Environmental Conditions
 Prone to weather and solar activity.
 Constrained by buildings, trees, terrain.

Limit to how much data a carrier wave can transmit without
lost packets impacting performance. Cost
 Wireless network cards cost 4 times more than wired
network cards.
 The access points are more expensive than hubs and
wires.

Signal Bleed Over
 Access points pick up the signals of adjacent access points
or overpower their signal.
Definition:- Wireless is when you can use the internet
without having a wire plugged into your phone,
computer, iPad E.T.C
Advantage:- not dragging around a cable and beaning
limited to where you can go.
Disadvantage:- can be slower because every object In
the way will help to slow it down. Also every device you
had will also slow it down.
Definition:- connecting using Ethernet cables
or connections to their network.
Advantage:- better connection, more reliable,
sometimes faster
disadvantage:- less flexible, not completely
safe.
Definition:- access a computer system or
service remotely via a telephone line.
Advantage:- Low Price, Secure connection –
your IP address continually changes, Offered in
rural areas – you need a phone line
Disadvantage:- Slow speed, Phone line is
required, Busy signals of friends and family
members

Facts: Emails and instant messaging are two
completely different things.
 When you send an email its stays on the
email server ( E.G:- Hotmail, Gmail etc. ) until
the receiver opens it. ( store and forward
system )
 Basics = address book, attachments and
multiple recipients.
Advantage:



Emails are delivered extremely fast when compared to traditional post.
Emails can be sent 24/7, 365 days a year.
Webmail means emails can be sent and received from any computer,
anywhere in the world, that has an Internet connection.
Cheap - when using broadband, each email sent is effectively free.
Emails can be sent to one person or several people.
No limit on how many people you can send it to.
Disadvantage:




Sometimes the internet might be down so you cant send them.
You could get hacked and your email could be changed.
The recipient needs access to the Internet to receive email.
Viruses are easily spread via email attachments (most email providers
scan emails for viruses for you).
Spam - unsolicited email, ie junk mail.
Hi mate.
How are you?
Just sending you an email to ask you
about the new text books. The class is doing so far
so good by the way the students are asking about
a trip. Could you email me back to let me know
how long you will be getting back to me.
See you later.
TO:- Main Recipient
CC:- Carbon Copy
BCC:- BLIND Carbon Copy
SMTP:- Simple Mail Transfer Protocol (SMTP) is an
Internet standard for electronic mail (e-mail)
transmission.
POP3:- Post Office Protocol 3 is a simple system with
limited selectivity. Incoming messages and attachments
are downloaded when users check their mail.
IMAP:- The Internet Message Access Protocol
(commonly known as IMAP) is an Application Layer
Internet protocol that allows an e-mail client to access email on a remote mail server.
IPhone – call people and Snapchat - wireless
IPad - face time - wireless
Laptop – internet and ppt for HW - wireless
House phone – to ring people – phone lines
 Ps4 – play games - internet cables
 TV – watch TV and use internet - internet cables
 Radio – listen to capital and radio one - wireless
 Xbox – play GTA 5 – internet cables
 Printer / fax – to fax people invoices – wireless

All methods of passing data between
devices, computers and users over a
network.
E.G: Computers, phones, machinery etc.
E.G: Audio, video, image and text.

UTP:- Cables are basic pairs of cables twisted
together.

STP:- Cables are basic pairs of cables but they have a
foil shield.
Max data transfer= 250 mbps.
Max range = 100m.
Benefits = twisting cancels out some interface & low
cost.
 Limitations = slower, less capacity than others & can
only be used for short distances.
 E.G: analogue telephone network.

Solid wire core separated from a copper outer
by a plastic insulated shield.
The inner cable transmits data and the outer
connects to the earth.
Max data transfer = 1000mbps.
Max range = 100m.
Benefits = fast & reliable.
Limitations = costs more than UTP/STP.
E.G:- connection to TV networks/aerial.

A technology that uses specially designed bundles of
transparent fibres to transmit light. Note: Some of the
applications of fibre optics are in medicine, where it is
used to view otherwise inaccessible parts of the body, and
in telecommunications, where it is used to transmit data
of all types.
Max data = 2.4gbps.
Max range = 50km.
Benefits = fast, long distances & littler interface.
Limitations = complex connection and equipment needed.
E.G:- Fibre optic broadband- connects to the BT panels n
the street then use coaxial cables to the house.

Short range data transmission using infrared
light.
Max data = 4mbps.
Max range = 100m.
Benefits = reliable.
Limitations = short range, device must be in
the line of sight.
E.G:- TV controllers & some phones now have
infrared.

Short wavelength radio transmission at very
high frequency.
Max data = 300gbps.
Max range = 100m.
Benefits = signal does not degrade over long
distances.
Limitations = device must be I the line if sight
& is affected by weather.
E.G:- Bluetooth.

Data is transmitted from the earth to a
satellite which relays it back to another
station on earth.
Max data = HUGE!!!!
Max range = 500km to 36,000km
Benefit = distances & speed
Limitations = expensive!!
E.G:- global communication systems.
