Enterprise Computing preliminary course

unit 2. networking systems and social

Computing so as the name suggests for

this unit we are taking a look at

Network systems and the infrastructure

that kind of sets up different types of

networks whether it be local or through

the internet but with a focus on social

Computing uh that of the social media

and the fact that we are trying to

encourage networks that bring people

together have interaction and set up

virtual communities for people to

interact through online platforms so you

can see a bit of connection here to what

was already alert with unit one but this

unit gets a lot more Technical and it's

probably contains the most terminology

out of all three preliminary units so

there's a lot to learn here and it leads

to a very messy mind map so let's see if

we can follow along

the first area is that of the

introduction to human-centric Computing

that we are developing systems with

individuals humans in mind and their

efficiency to get on the system and

engage in their work so areas related to

this is the effects of disruptive

technology so how when we have new

technology being invented or improved

communication it changes everything it

changes how we work it means we can do

work in different ways so it has that

effect on individuals in both a personal

and work related manner

the Innovations push change so when a

new technology comes out it means new

systems can be built with this new

technology and based on Trends and what

people are using that becomes kind of

New Foundations for what systems need to

include in order to support users in

order to make systems human-centric for

them

the next area is out of graph and

network Theory and in particular in

relation to social networking so with

that in social networking the graph

Theory relates to different users pages

and groups that they might be accessing

and tries to map that out and portray a

kind of picture of what users go to what

pages and what kinds of groups do they

set up and all that so it kind of

displays that in graph Theory

and then from there is the network

Theory which shows the flow of

information through all these elements

all right so they're the two theories in

place there and trying to map that out

in social media obviously it's very

important in social media in particular

if you're a platform for managing the

success of getting users getting them

interested and allowing for people to

grow and information to go through as to

expand their brands okay for specific

users

the next Theory then is the influence on

apps on social networking as with social

networking and outside of social

networking apps build on functionality

so when we include an app on within

social networking it expands what we can

do whether it can be we can embed a game

into the social media platform or it

could be a new element that can be

allowed for creativity and that can be

shared through social networking so the

apps build upon this and probably the

easiest way you can see that is through

your phone every time you download a new

app onto your phone you have a new

function something you can do okay but

we're talking about this in a social

media platform type of way where you can

share that element with your networks

and the people who you've been set up

with through your social media

the next area here is in hardware and

software's influence on the iot and iome

those two acronyms stand for the

internet of things which relates to all

the information available on the

internet that we can access and View and

then the io me the internet of me things

out there on the internet about myself

so there's a lot of categories related

to this specifically the impact on the

individual with this data that is out

there as well as the impact on

Enterprises we develop an identity and a

reputation online okay whether it be

ourselves or our business what we do

there's info out there and that will

influence how people see us or our

business now the other side of this too

is what's going on in the background the

hardware infrastructure that allows us

to connect with these networks so what

technology is running behind the scenes

so that will come up a bit later in this

unit

okay and the software protocols that

need to be used okay for specific types

of communication whether it be through

accessing websites accessing social

media accessing email there are

protocols in place so that all the

different types of technology that are

being used to access the networks mobile

devices computers game consoles are all

still speaking the same language when

online together

data obviously needs to be backed up

because if something happens to a

particular server on a network data

could potentially be lost and we still

want that data so we need backup making

secondary copies of data in place to

protect data whether it means storing it

offline or storing it at a different

server in a secondary location okay just

that it's somewhere else so that if

anything happens to our primary source

we can get it again

and then obviously things need to be in

place with regulation compliance and

cyber security and cyber security is

actually the third unit of Enterprise

computing's preliminary course okay but

the fact that things are set up to make

sure that businesses are bound by some

sort of rules for their ethical use as

well as the protection of data

and then finally characteristics related

to the startup and success of startup

groups okay people want to start

businesses online and we want to create

systems that people want to use there

are platforms available out there that

give people the tools they need to have

a network without having all the network

infrastructure ready they can start it

from their home and connect to their

website of the actual platform giving

them Network capabilities the chance to

find users for their businesses and

allow their brands to grow whether it be

through some sort of specific platform

or through social media they can share

their ideas they can share their

business and find customers

the next area of this unit is of storage

and workflow in Enterprise systems and

here we're going through a lot of the

technical components so that up the

benefits and limitations of digital

workplace so data is digital so we can

share it quite easily

okay through a variety of platforms and

through obviously making posts online

okay but then obviously there's

limitations too and potential

consequences too in the areas of

protecting our data protecting our

ownership of data that we need to be

mindful of and obviously think where

we're going to be sharing our data

we then got developments in network

connectivity and obviously a lot has

happened in recent years where we can do

a lot of our work that traditionally we

need to go into our workplace for from

home so obviously that first point there

is of remote working we can use video

conferencing software uh to have

meetings now and then after those

meetings we can do our work at home

okay and still have all my team members

faces on screen so we can still speak as

if we're in the same office another

layer to this is of file sharing there

are now Cloud platforms such as Dropbox

iCloud

um and even Microsoft to have their

OneDrive okay where multiple users can

access

um shared drives online and be working

on the same documents in those drives

okay to collaboratively develop their

work depending on whatever their

workplace is okay these items are set up

once again to allow users to work

remotely and then obviously tools that

support workflows with task delegation

who's going to be doing what so we do

have our once again face-to-face through

video conferencing but then we'll go

what specific items and apps that can be

downloaded where we can share schedules

through calendars and allow people to

know when things will take place because

we aren't in the workplace together we

are at home we are off site that

communication still needs to take place

so that can be automatically logged into

calendars so people know when things

going to happen okay but obviously these

things all support the changing nature

of work that moving away from the

workplace and now more so working from

home which is a bargaining chip people

you now use when going for jobs that

they want to work from home x amount of

days per week

the next area is data storage

requirements okay and look it's twofold

it depends if we're going to be storing

our data locally okay in our own drives

but more so these days online so what

capacity do we need okay of storage do I

need one terabyte of online storage or

more to support all my businesses data

we've got to think of that capacity

there and then accessibility

how will users access the data stored on

our Cloud platform or on our local

platform and then based on login

procedures what data within our storage

can each user access to because we've

also got to protect privacy and factor

in not all users within my Enterprise

need to have access to all work okay but

then also on the other side of that too

through making it accessible the fact

that people who might have impairments

or disabilities okay all of that is kind

of broken right down because they don't

have to travel into the workplace

anymore so having our data stored in

network drive supports accessibility

because people can just be seeing a

computer at home

and getting to the data they need quite

easily we've got to think of the

location of where this data is going to

be stored it's going to be logical so in

the cloud that's usually self-managed by

the platform we're using but locally how

is it a centralized drive is it going to

be a single centralized drive or maybe a

distributed model if we've got a larger

Enterprise and then obviously as alluded

to with accessibility security measures

that are going to be put in place and

we'll get to that in a bit later within

this unit too in order to protect data

ensure that the user is viewing the data

have a reason and right to be viewing

that data as per their task

the next area is our Cloud Computing

Services and really it is what is the

foundations of the services so whether

it be infrastructure as service which is

iaas software as service saas and

platform as service these will help set

up our cloud services in how we're going

to use them how people will access them

okay when we want to use these

and then we got the different types of

cloud-based data storage and it

basically relates to how it's going to

be used and the restrictions in place so

will it just be a public Cloud where

anyone can access and share data and

work on information is it going to be a

private Cloud which is more of an

internet where actual users need to log

in and be specifically a part of an

organization okay to view the data

within the cloud and then in these days

most of these cloud services may be

hybrid we can have General customers

coming in and viewing our data through

our sites but there is a portion within

our Cloud that is restricted to only

authenticated users and only they can

access it to do their work and then we

also have non-cloud on-premises okay

where we don't use cloud technology it's

pretty much just the data we've stored

on local hard drives there so Cloud

technology can be used in a variety of

ways to support our business based on

what we are doing

Okay the third area then relates to

network architecture and infrastructure

now we're getting into the technical

nitty-gritty of the actual networking

systems so the key components of it

required the Network Technologies Hub

switch routers gateways Bridges all of

that okay the on-premise stuff we need

in order to connect to the Internet or

to our customers okay what

infrastructure do we need is it just a

router that is connected to our phone

line or NBN that gets us to that network

connection we need or are we managing a

lot of the network ourselves from our

businesses location

and then how does that connect us to

cloud computing

this is supported by transmission media

okay and I already said NBN just before

what is connecting our devices together

both locally and through the internet to

get to our data that is online so our

wide mediums of twisted pair ethernet

um our coaxial cabling and then

obviously optical fiber which is the

main infrastructure in Australia now

okay within the roads of the NBN and

then our wireless mediums too our

microwaves our satellites and radio

signals that allow for wider area

communication without the need for wires

okay and obviously expanding upon the

data in order to connect to services

that are a lot further away without

needing a physical connection

the next area is the transmission

interference we are using these mediums

but what can affect our data while being

transmitted so things such as distance

between the nodes that are communicating

between each other and the topography

how specific nodes and mediums are laid

out on a network okay the mountain

ranges the height and the The Valleys

all of that will impact on how the data

is sent so there are physical and

environmental barriers that will also

include too so just physical barriers

could be transmitting high above a

Clifford trees being in the way or

specific buildings that have been built

okay that data needs to be transmitted

through okay unfortunately Landscapes

aren't all flat we have houses we have

nature all of that is impacting on the

actual data being sent between our

devices through our transmission mediums

and that obviously needs to be factored

into our Network infrastructure

okay we want to improve the data flow in

a sense so based on what we just said

about interference we need to think of

our antenna power our actual traffic

filtering by how many users are

accessing our Network and then how is

that being dispersed among our

technologies that we're using on our

Network to support that flow and give

users a good experience interacting and

getting to the data they need and

getting it back to them as information

and the things that can support that is

flow scheduling and traffic monitoring

which obviously a network administrator

needs to use but we are also talking

about Smart Systems too and we have ai

supporting this as well that is

monitoring this and then moving users

down different Pathways to support their

work on a network

okay once again we're talking about

graphene Network Theory but how can we

optimize this for users okay so we said

that social media needs this stuff but

we want to optimize it if our Enterprise

is going to maximize its success so the

adjacency and centrality of the actual

Network how are people getting to the

data they want how is that information

flowing and being shared through the

actual graph Theory

okay and how it's all set up how does it

give users that feeling of connectedness

to their data okay and allowing them to

expand through those social networks and

then what are the things that actually

weighted on these graphs okay so

obviously an area that needs to be

optimized for an Enterprise to maximize

their success

okay and then we've got to talk about

specific devices that support the

Internet of Things So once again getting

users onto the internet and knowing

specific protocols HTTP https

um that's incorporates SSL SMTP all of

that that is required to access certain

systems and services online

okay we then talk about machine learning

ml in conjunction with the internet of

things as I said before with managing

networks a lot of these are run by smart

AI systems that will help map users on a

network through specific routes of

mediums and devices to control the flow

of a network for their user experience

on the network so they don't get too

much lag or get dropped off an actual

platform okay ml the machine learning is

data driven so it will read numbers of

traffic and bits per second and

bottlenecking and bandwidth and all of

that and try to control this traffic

okay it will report any types of

diagnoses going place on the network and

then try to respond to this at this

stage we still want a physical human

network administrator there to support

the AI managing it with its machine

learning okay but a key area here is

automation this these types of tasks are

being taken over by AI because they can

it is numbers based they can make the

diagnostic decisions and respond to them

okay and they can operate 24 hours where

humans traditionally can't so we're

developing Smart Systems to allow these

Network systems to function for users

all over the world and control the flows

of traffic

okay we then and as mentioned before

need to focus on network access and

security now we already know that we

need logins and passwords to get onto

the internet and that controls users

allowing them to identify who they are

and what network rights they have to

access information okay and that

obviously passwords involves you typing

in a string of characters but then these

are also replaced with things such as

Biometrics okay and you see it on your

phone your phone these days you used to

have to put in a PIN code and you still

do sometimes but it can also just do

facial recognitions facial recognition

thumb print recognition that's

Biometrics it's reading your biology in

order to gain access into a system

we also have a thing known as captcha

okay and that capture that's used for

detecting Bots that's when you log into

a website with your password then you

might get a prompt come on screen of an

image and it might say what does this

word say and it might be in a more

calligraphy style of writing with a

grainness behind it and robots can't

read that because it's not in an OCR

type of character that they can read off

screen so only humans can interpret that

and it keeps the Bots out okay same when

you've got to click on the different

squares on screen saying where is the

traffic lights or where are the

mountains okay robots can't distinguish

that from a multiple panel of images but

humans can so it ensures that only

humans are getting into the system

and then um what also might be on our

systems too is that TPM The Trusted

platform modules which is a chip that is

used to support security measures so

support the booting of systems making

sure they are booting in a secure

location as well as checking the

signatures of users their digital

signatures that are coming from trusted

locations okay TPM supports that and

then finally software updates and you

guys are updating software on your

mobile phones and on your computers

software updates don't just uh update

for uh compatibility and efficiency they

also update for security okay so when

you update your software it could be new

protections are being put in place on

your systems through the OS to protect

you from malicious software and

unauthorized users because they've

picked up a pattern and then obviously

um the platforms are trying to defend

their users from this and they'll push

that stuff out through software updates

and then we've got the use of

intelligent home networks okay and um

you know we've seen things such as Alexa

where we can speak out loud commands and

things will happen in our home switching

lights on and off the ability to check

your mobile phone to see internal

security cameras with you on a house so

this internal intelligent home networks

that are being established where Digital

Data is allowing us to do a lot of

things from centralized devices from our

mobile phone from our computers and we

can control functions within our house

wow we're living in the future now

aren't we okay so the final area of this

unit is creating a basic Network okay so

obviously a lot of the creativity here

is happening in this portion of the unit

so we want to design and model a network

we are setting up some sort of network

okay and it might be fully physical

we're designing it we're designing it's

a logic what nodes are we using to

connect what devices and illustrating

what mediums are we using to connect it

all together

we are going to apply project management

Tools in order to do this okay so what

tools can we use so the use of hardware

and software to illustrate this here and

map it out and how we're going to set up

our Network there

okay we've got to have a bit of

knowledge on how to configure network

devices and that can be embedded into an

assessment so The Logical naming of

specific devices and then later on

updating these devices with their naming

with their properties and what they're

connecting with how to configure

specific protocols on a network and

configuring our actual devices for

connection to the Internet so that stuff

is potentially accessible within this

unit in relation to the preliminary

course and your knowledge in Enterprise

computing

okay also the implementation of security

protocols that we just mentioned before

the setting up of passwords the setting

up of potentially Biometrics if you've

got cameras enabled and all of that what

things need to be done in order to

protect users on a network so a working

knowledge of how to do that

we want to be able to optimize a

performance on a network so knowing how

to improve a bandwidth so mapping out

the routing of pathways on a network the

actual mediums we are using okay to

distribute data so as we know optic

fiber is the best wide medium but it's

expensive the actual nodes that are at

our Central nodes so our routers and

switches that might be centralized how

have we placed them out of network and

has our Network traffic mapped through

that all of that helps improve bandwidth

but then also the other side of it too

of updating drivers and firmware okay so

pushing out updates to our devices which

manufacturers do for phones and

computers all the time okay allowing the

actual software to be updated so it can

continue to be optimized and compatible

with new technology out there and then

the final area of this unit okay

evaluating the transmission it okay how

good is it can it be improved how can we

evaluate the I.T so looking at when data

is unsecured what can we do about it

there to ensure that it gets secured the

use of encryption the ability to

scramble data prior to transmission so

that when it is transmitted okay if it

does get intercepted it won't make sense

it can't be read but ensuring that when

the user gets it therein they have the

appropriate decryption key okay to

translate that data back into readable

form

okay so that comes along with it so they

can interpret the data there and then

finally just ensuring that our

infrastructure is set up in a way that

is logical and allows for data to flow

through our Network logically and

efficient so I hope this video has given

you an understanding of the network

systems and social Computing unit of the

Enterprise Computing preliminary course

it is the most technologically heavy

Topic in relation to understanding

content there is a lot here and as you

can see this mind map it's a big mess

but it is all terminology so learning

this terminology here and understanding

the relationship between terminology

will allow you to be successful at

understanding this unit okay and

remember we're not just learning about

Network Technology and infrastructure

but how it is used to support social

networking okay the fact that it allows

for the efficient interaction between

different users globally in many cases

with these Enterprise systems to allow

them to share ideas and have a pleasant

online experience through their

technology so no lag and they can get to

the data they want and it loads quickly

okay based on the efficient setup of

these Network systems
