How??

Have you ever wondered how data are input, processed, stored and output as information in a computer?

Below is a small block diagram to show it

                                Input devices

                           (Mouse, keyboard)

 

                       Central Processing Unit (CPU)                                              Output devices

                                                                                                                    (Monitor, printer)

                                             

 

           

             Main memory (RAM)         Secondary storage devices

                                                       (Hard disk)

1.       All the data are entered into the CPU via input devices. i.e. mouse, keyboard.

2.       The data are processed by CPU and send to the main memory for temporary storage.

3.       The data are sent to output devices and displayed through them. i.e. printer

4.       The data can be stored in secondary storage devices on the command of CPU. i.e. hard disk

Some of the ways to connect to a computer network.

A computer network is a collection of computers and their hardware components interconnected to each other electronically. Each computer can share resources, information and send or receive data with other computers in the same network. The speed of connection is faster than a normal connection to the Internet. There are various types of networks based on the medium used to transport the data, scale, communications protocol used, topology and organizational scope. There are different ways to connect to a computer network. Some of them are below:

Personal area network

It’s a personal computer network that is used to communicate among computers and devices that are close to a person. Computer, scanner, fax machine are some of the examples. It could be wired or wireless.

Local area network

Campus network

It’s a computer network within an area built by interconnection of local area networks. It is usually owned by college/university. The networking equipments and transmission media are all owned by the specific college/university. The network is linked to various computers within the campus territory.

Metropolitan area network

It is a network that covers vast amount of computers in a specific geographical area. The large computer network can be connected to a city, or a country.

Wide area network

It’s a broad computer network that covers a large geographical area.  It can cover an entire country; communicate long distances, or even intercontinental distances.

The devices can be interconnected with devices in wide distance in this network.

Jetman Flight at Grand Canyon West

Ever wanted to fly like a bird?

Yves Rossy nicknamed 'Jetman' was the first person to fly  a jet engine-powered wings. He developed and built a system comprising a back pack with semi-rigid aeroplane-type carbon-fiber wings with a span of about 2.4 metres (7.9 ft), powered by four attached Jet-Cat P200 jet engines  modified from large-model, kerosene fueled, aircraft engines. His first flight occurred in November 2006 in Bex, lasting nearly six minutes and nine seconds. He flew over some places. On 5 November 2010, he flew a new version of his jet-powered flight system and successfully performed 2 aerial loops before landing via parachute. He launched from a hot air balloon  at 2,400 meters (7,900 feet) and flew a total of 18 minutes before landing. The wingspan of Rossy's latest craft has been reduced to 2m. He says that the suit with the jet engine-powered wings attached will be available for human to fly in near future. Isn't that amazing? I cant wait to get my hands on them and fly like a bird.
