Security risks


Hacking
When a computer system is hacked it is normally due to there being a weakness on said system. The 'hacker' then takes advantage of this weakness to gain access to the computer and alter or delete files.
Identity theft
To steal an identity you must have all of the victim's personal information and data. This can be done by creating a false website which requires these details to gain access. 
Viruses
These can be found mainly in downloadable files and emails, as the user does not know these contain viruses, they open them and are then infected. They are capable of destroying your computer system or just affecting the speed of the computer.
Firewalls
Firewalls act as your computer's shield against potential threats. You can toggle the access for specific software. Devices such as routers would have hardware firewalls and its own set of firewall rules. Software firewalls should be in place in case a threat makes its way past the first firewall.
Passwords
Passwords are widely used by most websites that require user accounts. The password is needed to access the data and information stored in the account.
SSL
SSL stands for 'secure socket layer'. This encodes the data from the internet on the site's network connection. Any site that uses SSL has a certificate to show users that they are a safe and protected site.

Task 2 p2

User factors

Download speed
When making a website we must take into account the fact that some users of the website will have a low download speed, this will mean that the images and videos on the page will have trouble loading and could buffer too.

Browser
Certain internet browser do not support various file types that are used in websites, this causes errors when attempting to load the website. Using a more up to date browser will allow the user to use the website to its full extent. Or the case may be where a third party is needed, for example, software like flash player or java script is needed.

Age of equipment
If the age of the equipment you are using is too old, you will not be able to have a good screen resolution and graphics. This would mean that you would not be able to load more recent websites as they are made with a higher resolution and to a greater quality.

Device
Different devices have different resolutions and image quality. These devices can range fro hand held devices like mobile phones to smart TVs and computers. Some websites may not be able to be supported on these devices due to the difference in resolution.

Server factors

Bandwidth
The greater the bandwidth size the greater the amount of data users can download from your website. This would mean that you would have to pay more if you were paying for space on a server. 

Hits
The more hits your website has means it has more requests to the server that it runs on. The more people that are on your website, the slower the server will run. Eventually, if there are too many users accessing the server it will crash.

File types
Not every browser is able to load all file types, this can cause issues for the user when accessing your website.

Bitmap
These are images created from hundreds of individual pixels from a wide range of colours. These can provide very detailed images but can take a while to save and load as it is done pixel by pixel. Also when these images are enlarged they can lose quality as it becomes pixelated.

JPEG
These images offer a greater image quality but as the file size decreases through saving perhaps, image quality is lost.

Vector
These images are more simpler than Bitmaps when they are saved as they use lines and shapes instead of thousands of pixels. Vectors are far easier to re-size too as they keep their quality better than other file types.

MP3
These are small audio files most commonly used for music files. Due to them being small and easy to download and transfer, they are quite popular.

AVI
These are video files used mainly throughout windows software, these file types do not take up much memory.

Internet structure diagram

Web Architecture 

ISP

This stands for internet service provider, this provides internet access and domain registration names. these can be private or open to the community.

World Wide Web

This is also known as WWW. This is a system of hyperlinks that link to the internet which, when clicked, take you to the different webpages. When using a search engine like Google for example, the user can browse these webpages.

Domain Structure

This is where there is a group of computers which are all linked and have to have their accounts and security managed. A log in would be required to access this domain and its servers and receive as well as send data, for example, saving a document to the school network.

Domain Name Registrar

This is a company that lets you legally register your website domain name, this means that no one else can have this other than you. There are dozens of these companies that you can register with.

Web Hosting Services

These are companies that allow you to pay for some space on there servers to put your website on. You will have to pay continuously for the time and space on their server. These companies may also provide internet connectivity and may also maintain the website.

Components

Browsers

Web browsers are networks of information resources on the world wide web. Sources are identified by a URI or a uniform resource identifier, this can be a webpage, image, video or any other form of content that is available on the webpage. A web browser is a program that is created to allow the user easy access to both send and receive information and also view the information.

Web servers

These can be known as both hard and software. The web server provides internet access for the user and also provides content. The content can vary from amazon to youtube to countless other pages. The web pages are delivered using HTTP, HTML documents along with any other content is delivered using this.

Blogs

A blog is where a user can write down and publish anything they see fit, whether it be their opinion on a specific topic or just their day to day activities. 

Proxy Server

These are servers which allow access to webpages or other information which could not be access through the use of your normal browser. For example, if Smooth-wall blocked access to youtube, a proxy server could be used to navigate around this problem.

Router

This is a piece of hardware that all computers need to be connected to a networking package. A router will split itself across the various devices connected to the router, it will spread the package the most efficient way according to how much data the devices need or just an equal split.

Email

This is where users can send various types of multimedia documents to one another. This can now be done on various devices such as computers, mobile phones and tablets. This is normally available through the use of apps but can also be done through the use of web mailing services such as Hotmail.

Web 2.0

This is where webpages have become more interactive by changing from the standard HTML format, this allows you to share and exchange links with other users. Youtube is a good example of web 2.0 as this site is constantly updated with content shared between users.

Cloud computing

This is a mix between hardware and software, the cloud network is emitted from a server which stores and manages data just as if it was a local server. A good example of this is Dropbox as it allows you to upload your content to a cloud server and then it can be accessed from any other location as long as Dropbox has been downloaded and you can log in.

TCP/IP

TCP- Transmission Control Protocol

IP- Internet protocol

TCP/IP basically is the Internets communication language protocol. When you set up a computer it should come with a TCP/IP if not you can also set up your computer with a directed internet connection to gain a TCP/IP, as long as it is a computer that is able to send messages or retrieve data from its TCP/IP. As you can tell from the name this program works in a two part system. The first layer which is the TCP manages the information of assembling a message or making a document smaller so it can be send via the internet and then gets received by the second layer. The second layer is the IP which with control where the message or document is sent and makes sure it is sent to the correct address.

Online application

These are applications where the user may stream or download through the use of their internet connection.
