§The
Computer Networks
A
computer network is when two or more computers are connected together to share
information such as hardware, data, and software. Most common are the local
area network (LAN) and the wide area network (WAN). A LAN can range from a few
computers in a small office to several thousand computers spread throughout
dozens of buildings on a school campus or in an industrial park. Expand this
latter scenario to encompass multiple geographic locations, possibly on
different continents, and you have a WAN. Topology is the description of how
the networks are arranged and the features of topology are i.e. Star, ring and
bus etc...
Email
is a quick, simple and easy way of communicating to others and the reason why
an email is thought to be a networking site is that a person communicating
through to one or more people is thought as a networking site. However, if a person
wants to send work to a friend of theirs it would be that they would attach the
work through an email and once the email has been sent, the information on the
work such as hardware, software data or would go through a server that sends
the information of the work which is on the email attachment to the person and
the person would receive the work.
§The
Current Use of Computer Networks & Their Purpose
Computer
networking is currently being used to browse, buy, sell, research, socialize
and playing online games etc... Nowadays more and more people are researching,
buying/selling or socializing on networking sites such as face book, hotmail,
twitter and Skype etc...However, people generally use computer networking as a
way of communicating to one or more people such as to friends, family or work
colleagues. People use Skype as a social networking site to communicate to far
away relatives across the world. People on face book and twitter generally talk
about what they did during the day, what they’re going to do and general talk.
What’s
more is that why face book and twitter are the common socializing networking
sites is that you can upload videos, jokes, checking the latest news and
playing online games while socializing to other people. In addition Google is
the world’s biggest networking site and the reason is because most people
around the world use it for businesses purposes such as setting up websites,
for their organizations or companies etc. What’s more is that on company
websites such as eBay or Amazon are currently being browsed for what item of
product the person is looking for and they can buy it online buy paying the
other person directly.
§The
Reasons Why Social Networking Is A Great Way of Communicating
Social
networking is a good way of communicating with one or more people through
social networking sites such as face book, twitter, hotmail, MySpace, email,
msn, Bebo, instagram, bbm, Skype, podcasting, YouTube and Google. As an example
YouTube has videos that can be uploaded, removed, shared and viewed by millions
people across the world also, comments can be put beneath the video and they
can make humorous jokes, have debates or talk about a topic issue and have a
laugh or two about the video. Google is the world’s biggest search engine and
the reason is because most of the people use it on a daily basis.
In
another example of an everyday scenario for office workers, staff or boss use
email as a quick, easy and simple way of communicating to each other with their
workers, clients, staff etc... Such as when the next business trip is, who will
be promoted employee of the year or what improvements are needed to make better
the business. There are different kinds of emails such as hotmail or msn and
email is sending a message to someone electronically. Communicating by social
networking sites with Skype, face book or email are great ways of communicating
to those that are in another town or in another country.
§The
Kinds of Communications & Their Purposes
Communicating
is considered being able to talk to one or more people through social
networking such as the following;
How
is social networking a good way of communicating?
Face
book
Twitter
Hotmail
Msn
MySpace
Bebo
Instagram
Skype
BBM
Podcasting
E-mail
YouTube
Phoning
and texting, both are good ways of communicating to family and friends.
§The
Reasons a Computer Network Can Help Improve
Office
workers are reminded when the next meeting will be by receiving an email from
the boss or other co-workers, nonetheless a computer network is good because
you can have a website which will improve the business as well as the number of
people putting in positive comments about their business. A computer network can
help improve the business with a website to show the company as to how much
they’ve improved and what they needs improving. The structure can also be used
to see who the manager is > executive assistant > personal assistant >
receptionist > workers etc... Like a spider diagram.
A
computer can help improve the way we communicate and socialize with other
people using various types of networks and are very useful because it makes our
learning easier, the way we live simpler and what we are looking for quicker. A
computer network is important for those that work in industries, companies and
organizations etc... As well as communicating using computer networks. Although
they help us in our everyday lives computers are useful in offices because
using a computer network it can show you a structure of either you business or
company in which what’s good so far and what will need to be improved.
§The
Kinds of Ways of an Individual Communication Using Computer Networks
Ways
of individual communication using computer networks through social networking
sites i.e. Face book, webcam and twitter etc...,nonetheless face book and
twitter are optional and this is because the person with a face book account
can choose how many people they want to communicate, socialize and become
friends with. Webcam is most often an individual communication whilst using a
computer network, it depends on the number of people you are communicating to
by talking to them, in a way webcam is /isn’t optional. Individual
communication is better.
Individual
communication is a way of using the computer networks through the internet in
which can set up a blog. A blog is a website on which an individual or group of
users record opinions, information, comment, videos and pictures/photos, post
their thoughts etc... On a regular basis a person can set up a blog with just
them and their friends to know what they are doing up-to-date. Nowadays people
use the internet as a way of communicating with family and friends.
§The
Kinds of Ways of an Organisational Communication Using Computer Networks
Ways
of organisational communication using computer networks for example social
networking sites are used to communicate and people can start an organisation
to campaign/protest or to do a petition so you can get your point across.
Organisations as i.e. Human rights, non profitable, charity and international
organisations etc... However, organisations would use Wikipedia as a way of
communicating as it allows them to put information about the business also;
businesses use the intranet for communication. Intranets a business website
that’s only used by those within the business and no other person can access
the website.
Whereas
Amazon is a website which everyone can access because it sells products that
have been made in the UK and sometimes overseas international by importing them
and people can buy this by having a buy the specific product they’re looking
for by paying online or direct debit. Amazon is one of the most visited
organisational website that people have been on to look for, browse, buy and
sell products on. EBay is another organisational website that is quite similar
to Amazon. Moreover, Amazon and EBay could advertise their products on other
websites for people to click onto and browse on and this would expand their organisation
by using computer networks. Amazon and EBay are also a company as well as an
organisation.
§The
Kinds of Networks That Allow the Sharing Of Information, Hardware &
Software
Information
- you can use hardware i.e. a scanner, on a network and everyone can be
connected to it so that they’re information can go through the network to be
scanned and then to appear onto the screen monitor.
Hardware
- is a printer, scanner, photocopier, fax machine. However, a fax machine and
printer are quite similar and the reason is that they both have information on
which you can print off. > PRC prints off work and everyone can have access
to that one printer in the room.
Software
- if a person buy’s a Microsoft license
and install‘s it on a pc also known as a personal computer and anyone who were
to log in and uses that specific pc they can also, use the same software and
helps to prevent illegal software.
§The
Kinds of Networks That Are Used To Manage Resources
Large
organisations have a network administrator that could be responsible for
managing the network with the resources;
Making
sure it runs smoothly - no problems by preventing viruses, hacking and
preventing people from installing illegal software.
Deal
with issues proactively and reactively - proactively is preventing a virus from
entering the networks and reactively is a virus that’s in the networks but, is
prevented by installing an anti-virus.
Backing
up data - making sure that you save files on a hard disk drive and storing it
in a safe site.
Setting
up policies - ensuring that people do things properly such as i.e. passwords
etc
Providing
security - preventing viruses and hacking into the system etc
Organisations
that I am familiar with are i.e. Argos is a huge organisational company that
has a website to show what products they sell that people would be interested
in buying however, to improve their
productivity they could advertise on other websites such as business,
non-profitable and social networking sites etc... Because they can get more
people to buy their products which would increase their profit also, to see how
much they have improved in their productivity and how much difference they have
made in their organisation. To make the productivity even better is that they
could advertise on TV programmes or have a fun run by being sponsored. Amazon
is too, an organisational company but, is a little different to what Argos
does.
§The
Many Kinds of Network Issues
Speed
Small
server, limited processing and memory
Low
bandwidth, high contention
Costs
Extra
equipment and maintenance
Staff
skills
Network
specialist
More
user skills
Downtime
Needs
maintenance
Planned
downtime or emergency
Security
issues
Unauthorised
access
Malware
& hacking
Backups
§The
Speed & the Costs
Scenario:
In a workplace you had a small server to ruin the network, the people that are
in charge of the IT would need to limit to the number of people trying to use
the system at the same time.
Bandwidth:
Insufficient bandwidth could result in the server running quite slowly and
whoever, uses is will become frustrated. I.e. a film watched on YouTube lacks
of continuity because the picture keeps freezing.
Contention:
if too many people were to try and send messages or access a resource at the
same time, contention issues would result in as a system crash. However, until
the problem has been dealt with, no-one can access the system.
Speed
Issues: Can be avoided by having inadequate resources such as;
Memory
Fast
processing speed
Appropriate
wireless connections
Costs:
A networked system is simple than the same number of individual computers. The
interconnection of the hardware and the network operating systems adds to the
complexity > cost > of the system.
§The
Staff Skills & the Downtime
Staff
skills: Network users need higher skills than those that are have individual
computers. These skills can be provided through the training, in the following;
How
to log on
The
importance of passwords and keeping them secure
How
to share files
How
to use work areas
Downtime:
a network cannot run forever, without a period of maintenance. Access to the
network has to be suspended and this is called (planned) downtime.
Organisations
such as banks schedule a downtime at the least busy times for the network.
§The
Report OF Describing the Network Issues of an Organization Should Be Aware Of
The
network issues that the organization should be aware is of personal information
and this is where security risks comes in and the reason for this being is a
hacker can access you computer, your networking sites such as face book or
twitter, and can also, access you personal information, pictures, videos,
images, documents, etc...However, to install an anti-virus you can protect you
files as well as your computer from being accessed by someone else plus, only
allow access to your friends on you networking site and this way you can’t be
hacked and the person(s) won’t be able to access our networking site.
There
are major security risks that are in social networking and they are;
Scenario:
An example of a security issue is i.e. someone that could access your personal
record and share the information with everyone.
An
unauthorised access is when a data is addressed by controlling the access
rights, but, there are even more potential dangers and security issues.
Security
Issues are if someone can access a single computer, they can access the rest of
the computers which is potentially dangerous in which the person can access
others work folders, files, documents, email and confidentiality which is a
risk in having security issues.
Malware
also, known as (malicious software) is a software program which includes
viruses, worms and Trojans are designed to cause danger and security issues.
Viruses
are what damages files and can be prevented by installing anti-virus software
and by not opening attachments to emails from unknown sources.
Backups
are what we use in case a disaster strikes and the reason is that we need
backups is that it is essential that sufficient backups and trying to recover
it are in place to avoid possible loss of data.
Hacking
is an act in which a person(s) breaks into your computer system also; hacking can
be prevented though installing a firewall which creates a software barrier,
preventing other network users gaining access to your data on the computer.
§The
Kinds of Individuals & Organisations Using Networks to Improve Productivity
There
are those kinds of individuals and organisations that use networks to boost
their productivity by setting up a website or upgrading the website, like
Amazon offering a one day rush which is a way to attract customers that find it
interesting, quick, simple, and great to use, and with this your delivery can
come early 2-3 days too, however, there are other similar websites like eBay which do the same thing but, are 3
massive companies also, known as an organisation which use the networks to
improve their productivity plus, these organisations use the networks to
improve their productivity by advertising on the social networking sites such
as: Face book & Twitter which that is sued by many users of these social
networking sites all over the world. Other individuals use social networking
sites and the media to improve their productivity and even though the
individual isn’t in a massive organisation, the individual step by step can
create a mass organisation which can only be done though the use of networks
for the individual.
These
are the subsequent ways in which individuals and organisations themselves use
the networks to boost their productivity, the individuals can create a mass
organisation through the use of networks and so, can the organisations create
mass companies too.
The
individuals:
The
social networking sites
The
advertisement on t.v
The
sponsors on the websites
The
media, news, newspapers
The
jobs available on websites
The company’s
contracts sign
The
organisations:
The
social networking sites
The
advertisements on t.v
The
sponsors on the websites
The
media, news, newspapers
The
jobs available on websites
The company’s
contracts sign
There
not just these networks but, many other however, many o the other have their
own ways of having their many ways of use o networks plus, this is the greatest
way to have great revenue sales customs.
