Switch
A network switch or switching hub is a computer networking device that connects network segments.
The term commonly refers to a network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3 and above) are often referred to as Layer 3 switches or multilayer switches.
The term network switch does not generally encompass unintelligent or passive network devices such as hubs and repeaters
Function
The network switch, packet switch (or just switch) plays an integral part in most Ethernet local area networks (LANs). Mid-to-large sized LANs contain a number of linked managed switches. Small office/home office (SOHO) applications typically use a single switch, or an all-purpose converged device such as a gateway to access small office/home broadband services such as DSL or cable internet. In most of these cases, the end-user device contains a router and components that interface to the particular physical broadband technology, as in Linksys 8-port and 48-port devices. User devices may also include a telephone interface for VoIP.
A standard 10/100 Ethernet switch operates at the data-link layer of the OSI model to create a different collision domain for each switch port. If you have 4 computers (e.g., A, B, C, and D) on 4 switch ports, then A and B can transfer data back and forth, while C and D also do so simultaneously, and the two "conversations" will not interfere with one another. In the case of a "hub," they would all share the bandwidth and run in Half duplex, resulting in collisions, which would then necessitate retransmissions. Using a switch is called microsegmentation. This allows you to have dedicated bandwidth on point-to-point connections with every computer and to therefore run in Full duplex with no collisions
Hub
An Ethernet hub, active hub, network hub, repeater hub or hub is a device for connecting multiple twisted pair or fiber optic Ethernet devices together and making them act as a single network segment. Hubs work at the physical layer (layer 1) of the OSI model. The device is a form of multiport repeater. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision.
Hubs also often come with a BNC and/or Attachment Unit Interface (AUI) connector to allow connection to legacy 10BASE2 or 10BASE5 network segments. The availability of low-priced network switches has largely rendered hubs obsolete but they are still seen in older installations and more specialized applications.

Snake Temple - chor soo kong
The Snake Temple (simplified Chinese: 蛇庙; pinyin: Shé Miào; Pe̍h-ōe-jī: Tsuâ-biō) is situated in Sungai Kluang, Bayan Lepas, Penang, Malaysia and is perhaps the only temple of its kind in the world. The temple is filled with the smoke of burning incense and a variety of pit vipers. The vipers are believed to be rendered harmless by the sacred smoke, but as a safety precaution, the snakes have also been de-venomed but still have their fangs intact, visitors are warned against picking up the reptiles and placing them on their bodies for taking pictures. Local devotees believe that the temple's snake population has come there of its own accord.
The temple was built circa 1850 in memory of Chor Soo Kong, by a Buddhist monk who moved to Penang. Chor Soo Kong was born with the Tan surname in China during the Song Dynasty (960-1279). He was very serious about spiritual attainment and was ordained at a young age. Legend has it that Chor Soo Kong, who was also a healer, gave shelter to the snakes of jungle. When he died at the age of 65 after a lifetime of good deeds, he was bestowed the honorific title Chor Soo, meaning an eminent historic figure continuously revered by a community generation after generation. After the completion of the temple, snakes appeared on their own accord. The Snake Temple was originally named the "Temple of the Azure Cloud" in honor of the beauty of Penang's sky.
Believers from as far away as Singapore and Taiwan come to pray in the temple on Chor Soo Kong's birthday (the sixth day of the first lunar month).

Penang Hill
Penang Hill is a hill resort comprising a group of peaks in Penang, Malaysia. It is 6 kilometres (3.7 mi) from the city centre of George Town, and stands out prominently from the lowlands as a hilly and forested area. Penang Hill is also known by the Malay name Bukit Bendera, which refers to Flagstaff Hill, the most developed peak.
Topography
Penang Hill is mainly hilly granitic mass. The hill system is higher towards the northern part with its highest point at Western Hill, at an elevation of 833 m (2,723 ft) above sea level. Other than Western Hill, there are a number of peaks in the region, such as Bukit Laksamana, Tiger Hill, Flagstaff Hill and Government Hill. Flagstaff Hill is 735 m (2,450 ft) above sea level. A number of small rivers and streams originate from the region. Sungai Pinang is the largest of the rivers, and it starts from a number of tributaries in the area.
Land use
Because Penang Hill has a cooler environment, it has been a popular holiday retreat. A number of bungalows were built around Flagstaff Hill. The northern part of the Hills are not well developed. Government Hill, Bukit Timah and others are designated water catchment areas and no development is permitted.
Some recreational potential exists at the upper reaches of the river where the water is relatively clean. In a number of cases, sudden changes in ground level have resulted in a series of small waterfalls and rapids, where bathing, dipping and picnicking are popular.
The lower terrain of the Hills is used mainly for agricultural and residential purposes.
Accessibility
The most convenient way up to Penang Hill is by means of the Penang Hill Railway, a funicular railway from Air Itam to the top of Flagstaff Hill. Construction of the railway took place between 1906 to 1923, at a cost of 1.5 million Straits dollars. The railway was opened to the public on October 21, 1923. The 2,007 m (1 mile 435 yard) journey takes about half an hour and the train may stop at intermediate stations upon request.
The train is now out of service and is going through some upgrade and renovation. It will resume operation somewhere in early 2011.
Alternatively, there is a 5.1 km (3.17 mile) tarred road known popularly as the "jeep track". It is open only to the vehicles of hill residents. The "jeep track" is also used by off-road motorcycle enthusiasts to traverse up the steep terrain. It is a popular hiking route. It begins at the quarry at the entrance of the Penang Botanic Gardens and it takes a two or three hour leisurely hike to reach the top. Some of the more famous pit stops at the mountain are 52 and 84. At these pit stops, a view of the island is visible to hikers, who are able to get some water and tea prepared by locals stationed on the hill. Eighty Four is the last pit stop before the top of Penang Hill — approximately forty five more minutes from 84.
Jalan Sultan Yahya Petra, more commonly known as Summit Road, leads from the top station to the western part of the hill right towards Western Hill and Tiger Hill.
The eastern face of Penang Hill is well served by a series of roads and paths, for example, Moniot Road, Viaduct Road, and Tunnel Road. Moniot Road is named after a Frenchman, Michael Jules Moniot who surveyed it between 1846 and 1855. Moniot Road has been declared a Heritage Trail in 1995 by the Governor of Penang.
A system of bridle paths forms a picturesque labyrinth of walks connecting the different bungalows. Indian penal servitude prisoners shipped from Bencoolen, Sumatra to Penang during the second half of the 19th century built these by-paths.
Numerous trekking trails lead from various starting points in the lowlands to Penang Hill. The more popular trails include the Moongate Trail, trail from Air Itam Dam to Tiger Hill, trail from Hye Keat Estate and trail from the Municipal Park (formerly Youth Park). Some of the trails are used by farmers to transport produce to the markets of Balik Pulau and Air Itam
Plant and Animal Life
[edit] Flora
The most common forest type found on Penang Hill is the hill dipterocarp forest. Growing at higher altitudes are some of the submontane oak-laurel as well as coniferous trees. The Tree fern which is normally associated with higher elevations is also found growing here.
Penang Hill is scientifically important as a type site of many Malaysian plant species. In the past, botanists came here to collect plants for herbaria around the world. It is an area rich in biodiversity and has a great number of endemic species, some of which are so rare that their existence is endangered.
The rare and endangered species include the parasitic plant Exorhopalia ruficeps, which grows in the shady and damp undergrowth. The Penang Slipper Orchid (Paphiopedilum barbatum) is fast becoming over-collected and disappearing. The endangered witch hazel Maingaya malayana was rediscovered years ago and has since been propagated.
[edit] Fauna
Large mammals are not found in Penang Hills. Wild boars, small and medium sized mammals such as the squirrels, monkeys and tree shrews can be sighted. A number of species found in these hills are nocturnal. These include the civets, flying lemurs, flying civets and bats.
In the evenings, the characteristic calls of the cicadas and crickets are often heard. If one is discerning enough, the stick insect and leaf mantis may be found well-camouflaged among the vegetation.
Penang Hills have a rich bird fauna. Over 100 species or about 80% of the birds found on Penang Island have been recorded here. They range from the common garden species to rare deep forest inhabitants.

National Zoo Zoo Negara 国家动物园
Zoo Negara (literally National Zoo in Malay) is a zoo in Malaysia located on 110 acres (45 ha) of land in Ulu Klang, near Taman Melawati, in north-east Kuala Lumpur. It was officially opened on 14 November 1963. The park is managed by a non-governmental organization known as the Malaysian Zoological Society. For funding, Zoo Negara relies on gate collections and on support from donors and sponsors.
Zoo Negara is home to 5137 animals of 459 different species. Over the years, the zoo has transformed itself to an open concept zoo with over 90% of its animals kept in spacious exhibits with landscape befitting its nature.
Zoo Negara received MS ISO 9001:2008 certification in July 2007, and is a member of the South East Asian Zoos Association (SEAZA). The President and chairman of the zoo is Y. Bhg. Dato’ Ismail Hutson.
In 1957, the Malayan Agri-Horticultural Association (MAHA) opened a miniature zoo. After the creation of the mini-zoo, the idea of proper zoo gradually gained momentum, and the federal government chose a spot in Ulu Klang, Selangor next to the border of Kuala Lumpur. In the 1960s, Ulu Klang was an undeveloped green area. In 1963, the first Prime Minister of Malaya (now Malaysia) YTM Tunku Abdul Rahman opened the zoo to the public. Zoo Negara was known as the "Zoo in the Jungle" due to the greenery that surrounded the area.
The zoo welcomed its millionth visitor on February 14, 1966, just three years after opening, and by 1986, the zoo was welcoming over 1 million visitors per year.[1]
The area surrounding the zoo was covered with thick vegetation until the late 1970s as Kuala Lumpur underwent an economic boom. Given Ulu Klang's close proximity with Kuala Lumpur, the area was opened for large scale development as a planned residential area in the 1980s. It has expanded in terms of population ever since. The development has caused the zoo's surrounding areas and also increases the land value where the zoo is located.
In the late 1990s and early 2000s, there were plans to move the zoo to other locations in Selangor. However, the plans were largely unpopular among the public as it is seen as an effort by some developers to capitalise on the value of the zoo's large land. With the support from the Ministry of Natural Resources and Environment and the Selangor State Government, Zoo Negara will not be relocated.
The Amphibian World center at the Reptile Park has a variety of frogs and toads that originate from various habitats in Malaysia.

Football
1.)with ball 2.)defend player
3.) corner kick
4.) free kick
5.)Extraordinary
Common elements
Two teams of usually between 11 and 18 players; some variations that have fewer players (five or more per team) are also popular.- A clearly defined area in which to play the game.
- Scoring goals or points, by moving the ball to an opposing team's end of the field and either into a goal area, or over a line.
- Goals or points resulting from players putting the ball between two goalposts.
- The goal or line being defended by the opposing team.
- Players being required to move the ball—depending on the code—by kicking, carrying, or hand-passing the ball.
- Players using only their body to move the ball.
Peoples from around the world have played games which involved kicking or carrying a ball, since ancient times. However, most of the modern codes of football have their origins in England.[1]
AC milan and Inte rmilan football club Stadium
The stadium construction started in 1925 in the district of Milan named San Siro, with the new stadium originally called "Nuovo Stadio Calcistico San Siro" (San Siro New Football Stadium).[2] The idea to build a stadium in the same district as the horse racing track, belongs to the man who then was the president of AC Milan, Piero Pirelli. The architects designed a private stadium only for football, without the athletics tracks which characterized the Italian stadia built with public funds.[3] The inauguration was on September 19, 1926, when 35,000 spectators saw Internazionale defeat Milan 6–3. Originally, the ground was home and property of AC Milan. In 1947 Internazionale became tenants and the two have shared the ground ever since.
As well as being used by Milan and Inter, the Italian national team also plays occasional games there and it has also been used for the 2001, 1970 and 1965 UEFA Champions League finals. The stadium was also used for Internazionale's UEFA Cup finals when played over home and away legs but has never featured since the competition changed to a single final structure in 1997–98.
The stadium underwent further renovations for the 1990 World Cup with $60 million being spent, bringing the stadium up to UEFA category four standard. As part of the renovations, the stadium became all seated, with an extra tier being added to three sides of the stadium. This entailed the building of 11 concrete towers around the outside of the stadium. Four of these concrete towers located at the corner to support a new roof which has distinctive protruding red girders.
Inter is in the process of new stadium feasibility studies.
The first Rugby Union international took place at the San Siro when Italy played New Zealand national rugby union team in the 2009 end of year rugby tests.
he stadium is located in the western part of Milan. The stadium can be reached by tram, line 16 ends right in front, or using the Lotto metro station (line 1, red color, direction Rho Fiera) which is approx a 15 minutes walk from San Siro. Before sport events and concerts, a free bus connection is available from Lotto station to the stadium.
Dim Sum
DIM SUM
Dim Sum – Chinese Brunch :
In the west, dim sum came about as a natural result of 19th century Chinese immigrants - most of whom were from the Canton region - settling on the East and West coasts.Some gourmands believe that dim sum inspired the whole idea of "brunch" - combining breakfast and lunch into one large midmorning meal. It is true that the word brunch only came into existence in the late 1800's. (There's also some thought that the Denver sandwich - the quintessential cowboy snack - came about when a Chinese cook tried to adapt Eggs Foo Yung to suit western tastes).
But, back to dim sum. What types of foods are served at a typical dim sum lunch? Many of the dishes are either steamed or deep-fried. Among the former, you'll find everything from steamed pork spareribs and char siu bao - steamed buns with roast pork - to har gao, those wonderful shrimp dumplings with the translucent skin
Dim Sum Food:
Deep-fried treats include mini spring rolls and Wu Gok, a type of taro turnover. Not to mention whatever other culinary creations the chef may come up with. At one dim sum lunch we were treated to delicious shrimp dumplings wrapped in seaweed and topped with a dollop of salmon caviar.
Finally, there's dessert. Custard tarts are a must; you may also have a choice between mango or almond pudding. All of the above are washed down with copious amounts of green tea.
