Stirling

Stirling is a city and ancient burgh, in the Stirling council area of Scotland.

The city is clustered around a large castle and medevil old-town. It is a centre for government, retail, and light industry. Its population was 41,243 in 2001.
A former capital of the Kingdom of Scotland, Stirling was a royal burgh until 1975. In 2002, as part of Queen Elizabeth's Golden Jubilee, Stirling was granted city status.
Originally a Stone Age Settlement, Stirling has been strategically significant since at least the Roman occupation of part of Britain, due to its easily defensible hill and its commanding position beside the River Forth.
A ford, and later bridge, of the river at Stirling brought wealth and influence, as did its port. The town was chartered as a royal burgh by King David in the 12th century, with charters later reaffirmed by later monarchs. Major battles in Scotland's long conflict with England took place at the Stirling Bridge in 1297 and at the nearby village of Bannockburn in 1314.
Geography and Climate
Stirling is renowned as the Gateway to the Highlands and is generally regarded as occupying a strategic position at the point where the flatter largely undulating Scottish Lowlands meet the rugged slopes of the Highlands. The starkness of this contrast is evidenced by the many hills and mountains of the lower Highlands such as Ben Vorlich and Ben Ledi which can be seen to the northwest of the city. On the other hand, to the east of the city, the Carse of Stirling is one of the flattest and most agriculturally productive expanses of land in the whole of Scotland.
The land surrounding Stirling has been most affected by glacial erosion and deposition. The city itself has grown up around its castle which stands atop an ancient volcanic plug a major defensive position, which is, in turn at the lowest crossing point on the River Forth. Stirling stands on the River Forth at the point where the river widens and becomes tidal. To the east of the city the Ochil Hills dominate the skyline with the highest peaks in the range being Dumyat and Ben Cleuch. The Ochils meet the flat floodplain of the River Forth to the east of the distinctive geographical feature - Abbey Craig, a crag and tail feature upon which sits the 220ft (67m) high National Wallace Monument.
The climate of Stirling differs little from that of much of the rest of central Scotland. Warm, unstable air from the Atlantic Ocean is the predominant influence, with a prevailing southwesterly wind.
Government and Politics
In terms of local government, the city of Stirling is a part of the wider Stirling Council area, which governs on matters of local administration as set out by the Local Government etc (Scotland) Act 1994. Elections to the council take place every 4 years, with the next elections scheduled to take place in May 2007. Currently the council is controlled by the Labour Party. The Provost of Stirling is Colin O'Brien.
In terms of national government, there is a Stirling constituency of the Scottish Parliament with the MSP being Sylvia Jackson of the Labour Party and a Stirling constituency of the House of Commons represented by Anne McGuire of the Labour Party. As Scotland comprises a single European Parliament Constituency, Stirling participates in electing 7 MEP's using the d'Hondt method of proportional representation every 4 years.
Ecomony
At the centre of a large rural agricultural hinterland that encompasses some of the flattest and most productive land in Scotland, Stirling principally functioned as a market town with farmers coming to sell their products and wares in the large agricultural market that was held in the town. Today, agriculture still plays a part in the economic life of Stirling, given its focus at the heart of a large rural area, but to a much less extent than previously.
With Stirling's development as a market town and its location as the focus of transport and commmunications in the region, it has developed a substantial retail sector serving a wide range of surrounding communities as well as the city itself. Primarily centred on the city centre, there are a large number of chain stores. However this has been augmented by out-of-town developments such as the Springkerse Retail Park on the city bypass to the east of Stirling, the development of a large Sainsbury's at Raploch and a large Dobbies Garden Centre on the northwestern approaches to the city.
In terms of the services, financial services as well as tourism are the biggest employers in this sector. The financial services and insurance company - Prudential - have a large and well-established base at Craigforth on the outskirts of Stirling. In terms of tourism, the presence of such historical monuments as Stirling Castle, the National Wallace Monument and the key role which Stirling has played in Scottish history, as well as the scenery of the area, has bolstered Stirling's position as an important tourist destination in Scotland.
The University of Stirling and Stirling Council are two of the biggest employers in the area. Knowledge related industries, research and development as well as life sciences have clustered around the university in the Stirling University Innovation Park, close to its main campus. Other public sector agencies that are major employers in the city include Central Scotland Police, Forth Valley Health Board and the Scottish Environmental Protection Agency.
With good transport connections to the major cities of Glasgow and Edinburgh, Stirling is home to a large number of commuters, with 12,000 residents commuting to work in other areas, with 13,800 workers travelling in to the city.
Sport
Local sporting teams include the football team Stirling Albion F.C., and the rugby union team Stirling County. Footballers Billy Bremner and Duncan Ferguson were born in Stirling, as was rugby internationals Kenny Logan and Allister Hogg, jockey Willie Carson, and cricketer Dougie Brown.
Stirling is also a major centre of sports training and education in Scotland. The Scottish Institute of Sport is headquartered in a purpose built facility on the campus of Stirling University which opened in 2002. Also at the university in the state of the art Scottish National Swimming Academy as well as the Gannochy National Tennis centre which is seen as a tennis centre of excellence.


Furthermore the university itself has its own dedicated Sports Studies department and was ranked amongst the best in the United Kingdom for its provision of sports facilities, with the maximum 5 star award, shared by 16 other universities in the UK.
Stirling and its surrounding area has a number of 9 and 18 hole golf courses, the largest of which is the Stirling Golf Course, located in the Kings Park area of the city.
Education
The University of Stirling opened in 1967 on a greenfield site outside the town. Currently there are 9000 students studying at the university, of which 7000 are undergraduates and 2000 are postgraduates. Students of over 80 nationalities are represented at the university, with 14% of students coming from overseas. It has grown into a major research centre, with a large science park - Innovation Park, located immediately adjacent to the main university campus. Innovation Park has grown since its initiation in 1993, and is now home to 40 companies engaging in various forms of research and development. Stirling is also home to part of the wider Forth Valley College which was formed on August 1st 2005 from the merger of Falkirk, Stirling and Clackmannan colleges.
There are three main high schools in Stirling itself - Stirling High School, with a school roll of 940 pupils, Wallace High School with 950 pupils and St Modan's High School, located in the suburb of St Ninians.

Cuba

Motto: Patria o Muerte
(Homeland or death)



Getting there:

Almost all visitors to Cuba arrive by air, with scheduled flights arriving from Canada, the Caribbean, Central and South America, and Europe. The main gateways for US travellers continue to be Cancún, Nassau and Toronto. There are direct flights available from the USA, but to take them US citizens will need the permission of the US Treasury Department, which restricts travel to Cuba to journalists, researchers and a handful of other groups.

Getting Around:

Railway
Roads
Long-distance buses
Urban buses
Waterways
Seaports and Harbours
Airplanes

Attractions:
Old Havana
Varadero
Tropicana
Museum of the Revolution (Museo de la Revolucion)
Vinales Valley


Duration of Flight:

From London – Holguin – Havana
7 hours 15 minutes

Nightlife:

The nightlife in Cuba is rich and varied, but there are two spots that absolutely cannot be missed - they are recommended by Ernest Hemingway! Hemingway once supposedly said: “My mojito at the Bodeguita, my daquiri at the Floridita.” While the accuracy of this quotation is disputed, the proclamation has become a part of Hemingway lore. You can relive the great author’s nights on the town by getting drinks at these two famous bars, just blocks away from each other in downtown Havana. El Floridita was Hemingway’s preferred spot, and the bar stool he favored is currently roped off in his honor. Bodeguita del Medeo displays the quote attributed to Hemingway on the wall, along with some entertaining, decades-old Spanish graffiti on the walls and in the bathroom. Outside of Havana, the best cities for clubbing and bar hopping are Cienfuegos and Trinidad. Cienfuegos’ best-kept secret is the Palacio de Valle, a palace that contains a restaurant and a rooftop bar. The interior Arabian architecture is impressive, but the view from the top makes this an ideal place for dancing. Trinidad has all of the average spots, but if you’re looking for a unique place to salsa dance, try the Cueva Ayala. It’s located underground, in the caves that surround the Hotel Las Cuevas. It tends to get warm down there, but the open bar (free drinks with admission price) should help cool you down.
Accommodation:

Havana - NH Parque Central hotel
Halguin - Paradisus Rio de Oro hotel
Varadero Beach - Iberostar Varadero

3. A browser creates cookies to keep a record for the website owner to see how many people visit their site. They are updated so that websites can track users and see what websites they view.
4. A browser retrieves the HTML of the website and interprets it to show a viewable web page.
5. SSL – Secure socket layer.
6. Secure servers are given a certificate, link is encrypted as well as the data and a combination of send and receive ports.
7. Can a web page be viewed on more than one web browser and does the browser have the proper plug-ins to view the web page.
8. RSA is asymmetric and requires a lot of calculations whilst PGP is symmetric and uses 2 different keys to encode and decode. PGP is better as it does not require numerous complex calculations, PGP is more suited to handle internet traffic and is faster compared to RSA.
9. A public key is widely distributed to the public and a private key must be sent with the public key to ensure the information can be decoded.
Information systems homework


1. 3 functions of a browser: to allow web pages to be viewed
To convert html into a readable website
Forward and back buttons
2. Client side scripting is when the client uses scripting in order to be able to change a website because html is static and cannot be changed once it has been entered.
B)
3. Cookies allow a web server to send and receive information. A cookie is a file tat contains only one line of text, and is stored on the web servers or the user’s hard drive.
b) They keep track of the sites that have been visited and allow the web server to keep a hit counter of how many people have visited that site.
c) Site-tracking software collects and analyses the data that is generated by Internet traffic. The simplest type is a hit counter, which can be incorporated into a web page.
4. Credibility –
Bias – yes, as it would be telling people that the food is delicious and better than any other fast-food restaurant.
Accuracy – it would be as accurate as they could get the information.
b) The legality of this page is that it does not tell of the food risks involved when eating this food.
5. RSA encryption – this uses a numerous complex mathematic problem to scramble data.
PGP encryption – this uses RSA to encode the cipher key, it is slow but it does not include the numerous mathematic problem.
6. Educational entertainment which helps people to learn by making a subject fun. This usually include games and activity sheets.
b) Academic – educational website giving information about primary, secondary, colleges and universities.
c) Commercial – A company website advertising a product or service.
d) Personal – a website made for someone’s favourite band.

c) Switching packets works by sending the packets through routers which use a routing table to identify which routes are the best for sending the packets.

3. Protocol
Port number
Domain Name
Path
File Identifier
b)

4. A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services.
b) It allows websites to be stored without it directly contacting the internet everytime for a specific website and
c) The DNS uniquely identifies the ip address instead of the website address itself.
d) It will contact other DNS databases until it either finds the website he wants or an error message will appear saying that the website could not be found.

5. Class C
b) Subnets allow a network to be classed as a different network in order to allow more people to work with the network.

Chapter 1

Database Management System – This is a software package which, is used to create, manipulate and present data from electronic databases.

Database – this is a collection of related information about a ser of persons.

Traditional databases –

The storage of paper records was very bulky. Often requiring several large storing cabinets.
Data was often duplicated in several records.
Keeping records up-to-date was difficult and time consuming, and often resulted in data inconsistency, where duplicated values were updated in one record but not in others.

Benefits of using databases –

Searching and sorting operations can be performed much more quickly and easily.
Information is more easily available to users, due to improved methods of data retrieval.
Security and integrity of data is improved, due to the methods of data storage and updating.
No data redundancy (data duplication). In a relational database, data is never stored more often than is necessary.

Chapter 2

Relational model – the main idea behind a relational database is that data is grouped into entities that are related, in order to minimise data duplication and achieve data integrity.

In order to create a relational database, it is necessary first to produce a data model to represent the data being stored. The data model will indicate which entities are required, which attributes belong to each entity, and what relationships exist between the entities.

Basic Concepts Of Organisational Information Systems

2. Accuracy
• Human error reduces accuracy
• Different packages may be programmed to different degrees of accuracy (number of decimal places)for calculations

3. Volume
• Amount of data that can be processed in a given time
• Number of transactions in a given time
• Eg Banks, supermarkets process huge volume of transactions
• Need huge processing power, backing storage, output capabilities

4. Efficiency
• Combination of speed, accuracy and volume
• An efficient organisational information system will process a large volume of transactions accurately and quickly.
• Computerised info system is much more efficient than a manual one

Advantages of computerised System
• More accurate due to
• validation checks on entry
• automatic calculations
• This means less human error
Advantages of having a centralised database
• Any user can access the database from anywhere on the network
• Always be up to date and it is easy to control any changes.
• These factors make an organisation more efficient
What is an Information system?
• Group of interrelated components for input, processing, storage and output of information so it can be used for planning, decision making and control at all levels of an organisation.
• Can also be used by individuals.

What is the Internet?
• Started in 1960s for military use
• ARPANET – forerunner of Internet
• 1989 WWW was invented
1990s hardware and telecommunications became cheaper
Internet use became widespread.
1998 – Internet Explorer supplied with Windows 98
Intranet
• Same as internet but restricted to a LAN
• Same software and protocols as Internet
• Gives organisations more control
• Firewall needed between Intranet and Internet.


How does the Internet Work?
Transmission Protocols
• TCP – Transmission Control Protocol
Breaks data into packets at sending end and puts packets back together at receiving end.

• IP – Internet Protocol
Provides routing device with source and destination address
Packet Switching
Packet switching
Internet Hosting
• Host – any hardware component connected to the internet
• Every host has a unique IP address
• Eg 10.120.10.60
Packet Switching
• Routing – the method used to send data packets across the internet
Advantages of TCP/IP and Packet Switching
• Any network or hardware device can communicate with any other
• Can take any route from source to destination
• If any server or router is down the packet takes a different route
• Communications channels are used more efficiently as packets from many users can use same channel.
Server Side Hardware
• Server – Powerful computer
– Used to store data for other computers to access
– (eg web server, mail server)
• Routers and Routing tables
– Router stores and forwards data packets
– Checks IP address on packet, then checks routing table for best route.
– Routing table is database containing info about all network paths
– Routing tables are constantly updated

Internet Service Protocols
• HTTP – HyperText Transfer Protocol
Transfers and downloads web pages

• FTP – File Transfer Protocol
uploading and downloading of large files

• SMTP – Simple Mail Transfer Protocol
for sending Email between servers

• POP – Post Office Protocol
Used to retrieve Email from a mail server



Revision of Protocols
• New hardware and software – compatibility issues
• New protocols eg VOIP
Standard URL Structure
Proxy Server
• Sits between the client application and real server
• Intercepts requests to real server to see if it can fulfil the request itself.


Domain Name Server (DNS)
• Resolves a URL into the correct IP address
• User enters URL
• Browser accesses database of IP addresses through ISP
• Network of databases is accessed till IP address is matched to URL
• Process is called
HOST NAME RESOLUTION
IP Addresses always have 32 bits
IP Addresses
• Split into network ID and host ID
• 5 main types of IP address classes depending on network type and size
• 3 most commonly used are
• Class A, Class B, Class C
Class A IP Address
Class B IP Address
Class C IP Address

Examples
• 12.140.60.14
• 140.45.45.96
• 201.35.120.34
Network mask
• Used to separate network ID from host ID

Sub-net mask
• Allows a network to be divided into “sub networks”
• Network administrator can divide the host part into 2 or more subnets.
Example using a class B IP address
Example using a class B IP address
Subnet mask part of the Octet

• 192 11000000 2 sub networks
• 124 11100000 6
• 140 11110000 14
Example
For a class C network how many sub networks will the subnet mask 255.255.255.192 have?

Gateway Address
• Gateway is a link between 2 different networks.
• Each gateway address belongs to a different subnet.
• Router applies subnet mask and sends packets to correct network.
TELNET
• Allows a user to remotely control a server
• Log on with valid user ID and password
• Enter commands and they will be executed as if you were entering them directly at the server console
Revision of Protocols
• Revised and new protocols are developed due to
• Incorporation of new technology eg video streaming, mobile internet.
• New services eg VOIP
Internet Regulatory Bodies
• IANA
• Internet Assigned Numbers Authority
• Administers IP addresses and top level domains
• 2 types of top level domains
• Country codes and generic codes
