1. Contoh Report Text Tentang Laptop

A laptop is a computer which is easy to carry around. Its user can fold the laptop along its hinge for carrying. The laptop was created mainly for this particular reason. Computer parts were scaled to smaller size so this could happen.

The first laptop was invented in 1979 by British Designer Bill Moggridge. In 1982, two computer designers from Microsoft, Kazuhiko Nishi and Bill Gates, started their discussion concerning a new portable computer. The main thing about the computer was a new LCD technology. A year later the company launched its TRS-80 Model 100, which was a computer that looked pretty much like the laptops we know today.

The development of laptops continued with various upgrades and additional functions added. Laptops have a lot of advantages like:

-People can carry them anywhere, whether office or home.

-They can be used in a smaller space than an ordinary personal computer.

At the same time portable computers have several negative points like:

-Price is higher

-Computer thefts became easier.

-While used in the car they can cause car accidents.

-They break more easily than desktop computers.

A mobile phone (also known as a wireless phone, cell phone, or cellular telephone) is a very small portable radio telephone.

The first mobile phone networks were created in the late 1970s in Japan. A cell phone combines technologies, mainly telephone, radio, and computer. Cell phones work as two-way radios. They send electromagnetic microwaves from base station to base station. The waves are sent through antennas. This is called wireless communication.

There are different kinds of phones. A flip phone flips open, and is best for calling. A bar phone is shaped like a candy bar, and the keys and screen are on one face. A slate phone is a phone that has almost no buttons, and uses a touchscreen. Most smartphones are slates. A slider phone slides on rails. It can slide out number keys or a mini keyboard, but some do both. A swivel spins on an axle.

Many 21st century mobile phones are smartphones. These phones can be used for email, browsing the internet, playing music and games,and many other functions that computers can perform. This is because mobile phones basically are small computers. Older phones also used computer technology, but lacked many of the parts of a computer that were too big to fit into a phone. Modern phone makers have been able to use smaller parts. Most smartphones are also GPS receivers and digital cameras.

Bicycles are human powered vehicles, typically featuring pedals, a seat, two wheels and a frame. Before the word ‘bicycle’ become popular (coming from the French word ‘bicyclette’), bikes were typically called ‘velocipedes’.

Bicycles are used for transport, recreation, competitive racing, courier delivery and a range of other tasks.

Bicycles typically use a chain to transmit power to the rear wheel. Some bicycles feature suspension. This is especially common in mountain bikes where they are used to help deal with the vibration caused by uneven surfaces. Road bikes typically have thinner tires inflated to higher pressures than those found on mountain bikes, taking advantage of the smoother surfaces that roads generally provide.

Helicopters are agile aircraft capable of taking off and landing vertically, hovering and flying in different directions.

Helicopters have advantages over fixed-wing aircraft that allow them to access hard to reach areas, particularly useful in rescue situations. As well as search and rescue, helicopters are useful for tourism, medical transport, fighting fires, aerial photography, military activity and more.

The lift and thrust of helicopters are provided by spinning rotors, usually featuring two or more blades. Helicopters typically have one main rotor and one smaller rotor in the tail which counters the torque effect, stopping the helicopter from spinning in the opposite direction.

Around 1480 Leonardo da Vinci designed a machine resembling a helicopter which can be described as an ‘aerial screw’. The first working helicopter is believed to have been the Focke-Wulf Fw 61, first flown in 1936.

Airplanes are fixed-wing aircraft that are propelled through the air by engines. They are used for transportation, recreation, research and military purposes.

Some aircraft (usually military or experimental) are capable of supersonic flight (breaking the sound barrier) by traveling at speeds faster than sound (1235kph, 768mph). There have only been two commercial aircraft capable of supersonic transport, the most well known of these was the Concorde which flew between major cities such as London, New York and Paris until 2003.
