UNIT 28 P2

When considering how my website will operate there are many factors that will effect a user’s use of my website, these are not issues with the site it’s self but issues with the user’s actual personal computer system or landline connection, a summary of potential issues are listed below.

-Web server capacity
A Web server is a program that, using the client internet provider which connects to the World Wide Web's Hypertext Transfer Protocol, this then serves the files that form Web pages to Web users (whose computers contain HTTP clients that forward their requests). Every computer on the Internet that contains a Web site must have a Web server program. The leading Web server is Microsoft's Internet Information Server it is the most widely installed and used server. A common way that you could increase the capacity of the web server is to upgrade your server to a better server, this is a common debate with most tech savvy people on which is best as most people hate internet explorer so must switch to servers like Google Chrome or Firefox.
-Bandwidth 
Bandwidth or the other term Data Bandwidth are common terms that are used to refer to measures and they represent the available or consumed data in the communication resources such as your internet or download speed and they are expressed in Bits Per Second, like for example:, kbit/s, Mbit/s, Gbit/s. The size of the bandwidth can affect the connection speed of the internet so the higher the bandwidth the better the performance and often the higher the cost.

-Executions 
Executions within computers and software programs are simply the process by which a person’s computer or any machine can carry out certain instructions of a computer program.

When the instructions are given by the user by typing or other means they trigger in the program a sequences of actions on the machine and those actions produces effects that are according to the instruction and the semantics of the instructions in the program this could be running Google or opening a Word document. In some cases programs for a computer may be executed in a Batch Process without someone interacting with that program or a user with type commands into an interactive session of an interpreter such as start-up actions or Auto functions.

-Download Speed 
Download speed form the User side is how long it would the selected webpage to load, photos to load or things to download once requested. The measurements for the time it would take to load the page and the speed of the page are completely different issues as some webpages have more content than others like pictures and videos. For example having slow internet connection or having a computer that has a lot of information stored on it is more likely for it to run more slowly than it should and maybe causing the webpage to time out or crash, and so it’s best to get the best connection possible and even if it has to cost more to run but it is more likely to give you much more, quicker and stronger download speed making a better use of the computer. If the download speed is running slowly because you have be downloading too much you can make this better by getting a new processor or a better connection.

-Cache Memory 

Cache Memory is in the short term used for the RAM that the CPU can access easier and quicker than it would with a normal RAM chip.  The CPU will use the Cache Memory to store the instructions that will be required to the run the applications/programs the user wishes to use. You can find larger caches and that will operate at higher specific speeds, also these are now considered to be the core of the CPU your pc uses. Other caches on the other hand can be simpler and differ and also they will be slower when used. Your computer will start to run more slowly because the cache memory is getting too full like trying to stuff a suitcase, you can improve this by simply gaining a better cache memory bank.

-Processor Speed 

Processor speed is the speed of which the microprocessor gives out instructions to the rest of the system. The CPU has got a fixed number of ticks (basically time) in which it has to operate the instructions, so the faster the clock the better, this leads as the more instruction it gets and can be executed in good time. For example 2 CPU's may have the same clock speed but it may not perform the same as some will run faster than others and some will have faster microprocessor like the differences between computer systems, which means that a single calculation can be performed in just 1 tick, but when the technology advances some of the Microprocessors are not even what is known as Superscalers, which means that they can produce more than one instruction per clock cycle. If you wish to increase the speed of the processor then you can upgrade your processor and you could clean out the history that is on your computer for processors a simple way of looking at this is like instead of using an Intel i3 processor you can upgrade to an Intel i7 for overall increased processing speed.

UNIT 28 D3

Following on from the excellent work creating the database for Kingswood School’s media department, you have been asked to plan, design and create a website for all the film reviews to be displayed. There is also a need for film trailers to be displayed on the site so the user can view and select the film prior to purchasing the ticket. The website also needs the functionality to be able to allow users to pay for films and add reviews after they have watched the particular film.  The website needs to feature two-way interactivity as well as being multi-age.

-BELOW ARE SCREEN SHOTS OF MY WEBSITE AND DESCRIPTIONS OF HOW THEY FIT THE TASK-

 This page fits the defined purpose as it shows the correct dates and information about films and showings. It provides a correct and age friendly easy to navigate home page with easily visible buttons it is as the brief says "interactive" and "multi-age" as the house style is appealing to all age groups and follows the schools own uniform colour scheme.

 the payments page I designed and created was as the brief stated "functional" and easy to use when paying for a movie rental, the design follows my house style and creates a professional look. It features the design critical "two-way interactivity" and is simple to use.

 My review page was in line with my house style and was eye-catching as well as fully interactive and was able to link to other sites for comparing reviews and allowed users to give feed back on the professional reviews on the films being shown.

 This "film" page show effectively and clearly the information about times, dates and locations of viewing for films and shows in a manner which users of all age could understand and easily extract regardless of technological understanding

In this "trailer page" it shows as the brief states a full page of film trailers which are featured in the site. As with all other pages it allows a varying degree of quality in video for some older systems and a easy to use "two-way interface", which is age friendly 

UNIT 28 M3

After completing my website, I allows several of my target audience use the website and test it out and give user feedback and critical evaluations on the overall effectiveness of the system and its pros and cons.
From this data I was able to come to the conclusion that there were 2 areas my website could adapt and change to become a more appealing system to my target audience.
1. The color constancy on the pages, that it doesn't follow a house style.
2. The reviews page has a click to view button which lacks functionality.

UNIT 28 P1, M1, D1

This is a simple diagram of how we as independent users connect and use the internet. Below the diagram is an explanation of some of the features on the diagram and some features critical to internet usage.

ISP
ISP (Internet Service Provider) is an business such as Sky, BT or Talk talk that provides and installs a way to access the internet and this is directly connected with the clients that subscribe to these business by using copper wiring, wireless or by fiber-optic wire installation. Different businesses of the Internet Service Providers may be an Non- profit organization such as county councils or profit organizations like Virgin media.

Web Hosting Services

This allows people or organizations to make and design their own website on the internet. All web host companies provide space on servers that is owned or leased for use by the clients. As well as providing internet connections. This is what they call a "Data Centre", web hosts also provide data spaces and connectivity for other services that are located in the Data Centre, and they may also maintain the day-to-day running of the website.

Domain Structure
a domain structure is a group of computers which maintains its own security and accounts management on a local level, for example the primary domain controller. All logins for local accounts are done within the domain, and it has its own servers for locally logged on users much like our local school network.

Domain Name Registrars
domain name registrar is an organization that manages the reservation of internet domain names. A domain name registrar must be authorized by a high-level domain registry agency. The management is done in accordance with the guidelines of the designated domain name registries and to offer such services to the public as well as in combination to online laws and laws of the country which it originates.

Worldwide Web

The World Wide Web is a system of linked hypertext documents that are accessed through the Internet. With a browser such as Google or Internet explorer, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them through hyperlinks.

Mail Clients

Mail Clients is a computer program that is used for accessing a user’s email and allows them to manage their email inbox. Clients can refer to any system that is capable of handling the users email and regardless of it being a mail user agent, a relaying server or a person typing manually on a terminal. Also a web application that provides message management, composition and reception functions is sometimes considered an email client but is more commonly known as webmail.  An example of this would be Gmail.

Components

-Hardware

Web browsers are more commonly known as Browsers, and it is a software application gaining access to information resources on the Worldwide Web. An information source will be identified as a Uniform Resource Identifier (URI) and this maybe a webpage, image, video or any other piece of informational content available on the web. Hyperlinks are also presented into resources and enable the users to easily navigate their selected browsers to the online resource. Also a web browser can also be defined as a program that is designed to enable easy access for the users to get, send and view information or any other resources that come from the internet such as a user friendly interface that is simple and easy to use, very much like Google chromes.

-Web Server 

Web Servers can also be referred as hardware on a computer or a software application on a computer. This helps to deliver web content to the user and it can be accessed through the internet, and the most common used of the web servers are called websites like Facebook but other web servers that offer that same as website and they are applications such as 'gaming', 'data storage'. The primary function of a web server is to deliver web pages on the request of the user using the HTTP. This means that the delivery of the HTML documents and any additional content that may be included by a document, such as images or any other content the website produces.

-Web 2.0

Created in 1999 and it was a way of describing next generation websites. Although it suggests that the updated version of the Worldwide Web this is a common misconception it doesn't refer to an update to any of the technical specification but they will have changed by the software developers and the users that use the web. A Web 2.0 site allows users to interact and collaborate with others in social networking sites, such as Facebook, such as Youtube which allows users to link and share with many other sites seamlessly.

-Blogs

Blogs are discussions or informational online sites that get published on the internet and that these documents consist of entries or posts. Also these are posted in the typically displayed way of being in reverse chronological order meaning the most recent will appear first. Up-till 2009 these posts were posted individually or on occasion in small groups of 3/4 and often covered by the same subject and even more recently 'multi-author blogs', 'MAB's' have been developed and with posts that were written in large numbers of authors and that it professionally edited.  MAB's from newspapers, other media outlets, universities, and think tanks and similar accounts of ever increasing number of blogs being released onto the internet. The rise of Social Networking sites like Facebook helps to migrate the MAB's and single bloggers into societal mainstreams. A blog is comparable to an online biography.

-Online Applications 

Online Applications or a Web Applications is an application that is accessed by the user that is on a network such as the internet. A Web Application may also mean a computer software application that is coded in a web-browser-supported program language very much like JavaScript and combined with rendering-browsers like HTML. A majority is interactive, allowing users to leave comments and even message each other via GUI widgets on the blogs or by special boxes around the page, and it is this interactivity that distinguishes them from other static websites; also blogging can be seen as a form of social networking. Many blogs provide commentary on a particular subject, others function like personal online diaries, and others function more as online brand advertising.

-Cloud Computing

Cloud Computing is the use of computer resources both hardware and software that is delivered as services over networks such as the internet. Also the name comes from the use of the Cloud-Shaped symbol as an abstraction for a complex infrastructure that contains it in the system diagram and Cloud Computing trusts any remote services with the user’s data and software. Users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user's data are stored on servers at a remote location this is like X-box 360 online cloud data service which allows users to monitor their accounts anywhere.

Protocols
Internet Protocol or IP Addresses are the universally-used form of addressing on a TCP/IP network. These Network-layer Addresses are uniquely eidetic from each of the networks interfaces, these sever as the mechanics by which the data is routed to the corresponding network on the internet, and there will be the correct device on that network to ensure correct operational function. Most people do not realize that there is an additional level of addressing that will occur at the point of the transport layer which is called TCP/IP set above is the IP address. Both of the TCP/IP transport protocols TCPs and the UDP use concepts of ports and sockets for the virtual software addressing and that enable the different functions of many different applications simultaneously on an IP device to work properly as a result it is very critical to the working and operation of the World Wide Web.

SMTP

Short for Simple Mail Transfer Protocol, a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP (Post office protocol)  or IMAP (Internet messaging access protocol). In addition, SMTP is generally used to send messages from a client to a mail server. This is why you need to specify both the POP or IMAP server and the SMTP server when you configure your e-mail application or else it will not work effectively.

HTTPS

Hypertext Transfer Protocol Secure (HTTPS) is a communications protocol for secure communication over a computer network, with especially wide deployment on the Internet. Technically, it is not a protocol in and of itself; rather, it is the result of simply layering the HTTP on top of the SSL/TLS protocol, thus adding the security capabilities of SSL/TLS to standard HTTP communication.

In its popular deployment on the internet, HTTPS provides authentication of the web site and associated web server that one is communicating with, which protects against man-in-the-middle attacks. Additionally, it provides bidirectional encryption of communications between a client and server, which protects againsteavesdropping and tampering with and/or forging the contents of the communication. In practice, this provides a reasonable guarantee that one is communicating with precisely the web site that one intended to communicate with (as opposed to an imposter), as well as ensuring that the contents of communications between the user and site cannot be read or forged by any third party.

TCP/IP

Short for Transmission control protocol/ internet protocol , the suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the Internet, making it the de facto standard for transmitting data overnetworks. Even network operating systems that have their own protocols, such as Netware, also supportTCP/IP. Overall making it a pivotal protocol.
