Some Key Terms- The Internet and Web Design

Define the term – Protocol

Is the special set of rules that end points in a telecommunication connection use when they communicate. Protocols exist at several levels in a telecommunication connection. For example, there are protocols for the data interchange at the hardware device level and protocols for data interchange at the application program level.

What are the following protocols used for?

TCP/IP-
Transmission control protocol (TCP), which uses a set of rules to exchange messages with other Internet points at the information packet level Internet Protocol (IP), which uses a set of rules to send and receive messages at the Internet address level. It can also be used as a communications protocol in a private network. When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.

Http-
Hardware and/or software that connects computer networks and allows them to communicate. HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. As soon as a Web user opens their Web browser, the user is indirectly making use of HTTP. HTTP is an application protocol that runs on top of the suite of protocols.

Smtp-
SMTP (Simple Mail Transfer Protocol) is a TCP/IP Protocol used in sending and receiving e-mail. However, since it is limited in its ability to queue the messages at the receiving end, it is usually used with one of two other protocols, that let the user save messages in a server mailbox and download them periodically from the server.

FTP-
File Transfer Protocol (FTP), a standard Internet protocol, is the simplest way to exchange files between computers on the Internet. FTP is an application protocol that uses the Internet's TCP/IP protocols. FTP is commonly used to transfer Web page files from their creater to the computer that acts as their server for everyone on the Internet. It's also commonly used to download programs and other files to your computer from other servers.

What does GUI stand for? What was used before GUI?
Graphical User Interface. It is a graphical (rather than purely textual) user interface to a computer.

Command Line Interface (CLI) was used before. It is a mechanism for interacting with a computer operating system or System software by typing commands to perform specific tasks.

There are two methods of data transmission – serial and parallel. Explain the difference between them.

Serial transmission bits are sent over a single wire individually. Whilst only one bit is sent at a time, high transfer rates are possible. This can be used over longer distances as a check digit or Party Bit can be sent along it easily.

Parallel transmission Multiple wires are used which can transmit multiple bits simultaneously, which allows for higher data transfer rates than can achieved than with Serial transmission. This method is used internally within the computer.

Define the term “URL”. Explain the components that make up the URL.

Uniform Resource Locator (URL), is the address that defines the route to a file on the Web or any other Internet facility. URLs are typed into the browser to access Web pages, and URLs are embedded within the pages themselves to provide the hypertext links to other pages.

The URL contains the name of the protocol to be used to access the file resource, a domain name that identifies a specific computer on the Internet, and a pathname, a hierarchical description that specifies the location of a file in that computer.

In the context of data transmission, what is “error detection”?

A set of techniques that can be used to detect errors in received data. Techniques that are applicable include parity checks involving parity bits, checksums or a Cyclic Redundancy Check.

Name and explain one common method of error detection.

When u miss spell the URL or whatever u are typing to search.

Assessment Part B

Draw up word tables to explain how tables (with fields, data types), queries and forms could be used to provide a solution.

JUST DOUBLE CLICK THE PICTURES TO VIEW TABLES CLEARLY

Switchboard Form-
This form is created like a menu of the Digital Music Database. It lets you explore and browse into other forms from that page.

Artists Form-
This form gives you information about the artists or band and background information.

Select Artist Query-
It lets customers easily search about an Artist rather than browsing the Artists form.

Music Form-
Gives you detail about the song, album, genre and a sound of the song and a picture included.

Search Song Query-
You can just type the song you want to see rather than browsing 10 records/songs.

Song Tracks Form-
It is just a form which helps you to browse only songs and listen to them.

Search Track Query-
It is there to search just one track you are looking to listen for.

Assessment Part A- Question 2

Discuss what advantages such a system has over conventional methods of organizing and previewing music?

Lets the customers browse through the database themselves without any difficulties. They do not require assistance.
It provides background information of various amounts on the music and artists.
It is like an online library, which lets you browse through quickly.
The customer makes much more profit in looking at it rather than buying the album which contains the song you like and not the artist’s information etc.
The database has organized the digital music in a way you want it to be like (alphabetical songs).
The artists, soundtracks and music forms are there if you just want to the search one of them like soundtracks or information about the artist which navigation buttons lead you through.
The database is uncluttered and clearly organized to use from customers.
free sevice for customers.

Assessment Part A -Question 1

What ethical / legal issues need to be considered when implementing this database? Explain.

Privacy is a legal issue when implementing this database as it has to be considered to keep the privacy of the Artist. As it might not keep the Artist’s details confidential with their concern.
Copyright is a legal issue as it concerns the plagiarism of the songs in the database if they are from a private or public album and/or the internet. These songs are from another owner who needs to be credited. You should always have the permission from the Artist. If this doesn't occur without the artist knowing then it is a copyright law called 'music priacy' general term referring to the illegal duplication and distribution of sound recordings. The pictures of the Artist have to be taken in concern as it might be a copyright law from the photographer who took the picture and doesn’t want his or her’s photograph copied.
Copyright is also an ethical issue as you do not want to plagiarize someone’s ownership of their photograph or songs which is morally wrong.
The Government’s rules and regulations is a legal issue for people under a certain age which might restrict them to search and browse on this database. This shouldn't be a worry as the database doesn't involve anything to restrict a certain age but the precautions have to be taken.

Thus all these issues had to be considered when implementing the 'digiatl music database' as this database does include images, music, and artist's information.

Types of Databases & file,record,field

There are a lot of Databases like-

Mobile phones
Yellow pages
Address Book
Dictionary
Google

This is an example of a database of music containing album titles, song titles, artists, genre.

ON the left if what a record is, on the top is the field and the circle around the whole thing is a File.

Definitions of Database

This year we are learning about Databases.

This are definitions which will come in help sometime-

Field- A space allocated for a particular item of information. In database systems, fields are the smallest units of information you can access.
Record- Records are composed of fields, each of which contains one item of information.
File- A collection of data or information that has a name, called the filename. Almost all information stored in a computer must be in a file.
Query- A request for information from a database.
Database- You can think of a database as an electronic filing system. Traditional databases are organized by fields, records, and files.
Report- A formatted and organized presentation of data. Most database mangaement systems include a report writier that enables you to design and generate reports.
DBMS- A collection of programs that enables you to store, modifies, and extract information from a database.
Data Dictionary- In database management systems, a file that defines the basic organization of a database. A data dictionary contains a list of all files in the database, the number of records in each file, and the names and types of each field.
Data Type- In programming, classification of a particular type of information.
