TECH NEWS:
This section later on we'll learn about media information network. Current media network is divided into two types of media, namely wired and wireless media or cable.
Cable Media
Cable Media has advantages i.e. a network condition in connect the cable capacity is more reliable and the support is greater.
Cable has communication media:
1. Twisted Pair Cable
-Good known as network cable
-The price is relatively cheap
-Used for distance-the distance is not too far
-Easily affected by disturbances
-Data speed that can be supported is limited to 10-15 Mbps.
2. Coaxial Cable
-Generally in use on television
-Used for relatively greater distance away
-Higher data speeds of 30 Mbps
-The price is relatively not expensive
-The size of some of Tuisted Pair
3. fiber optic Cable
-Relative price still expensive
-Used for relatively farther
-Higher speed at 100 Mbpz
-Relatively small Size
-Hard on the influence of disturbance
-Relatively difficult Installation
Media Without Wires
Communications use media without wires can be through the medium of a vacuum of air in large areas. Form of communication using media files wirelessly for example electromagnetic signal transmitting by satellite space.
The use of hand phone to send electromagnetic signals and use of bluettooth for data transfer. Wireless communications media among others as follows:
1. Microwave
-Is the use of electromagnetic waves of high frekuesi
-Transmission Distance is limited to between 20-30 km
-Speed up to 50 Mbpz
-Used on radar
2. Radio Waves
Radio waves are a form of electromagnetic and formed when electrically charged objects in modulation (in praise frequency). On the frequency found in the frequency of electromagnetic sepktrum.
-Frequency ranges between 3
-Khz to 3 Ghz
-Can be used to send files or voice over the air
-Used in the communication of hand phone
3. Infrared
-Used for short range communication
-Speed up to 4 Mbpz
-Used on a remote control television
