"observe your child"

Bullying has become a typical expertise for several youngsters and teenagers throught out our nation daily.  Recent surveys from the u.  s. Department of Justice, indicate that as several as half all youngsters that enter their college threshold daily square measure browbeaten at it slow throughout their year, and a minimum of half-hour square measure youngsters with special wants...FACT!

Bullying behavior is physical, verbal, racial, ethnic. Bullying by ladies is a lot of usually verbal, typically with another lady because the target.

Children United Nations agency square measure browbeaten expertise real suffering that may interfere with their social and emotional development, furthermore as their college performance. Some victims of bullying have even tried suicide instead of still endure such harassment and penalization.

"Linear Topology"

Computer Networks with Topology coherent ("Linear Topology") commonly referred to "Linear bus topology", this layout includes general layout. One main cable connecting each connection point (computer) that is connected to the connector called Connectors-T and the ends must be terminated with a terminator (terminator). BNC type connector used (British Naval Connector: Connector Maritime Britain), actually is a BNC connector name is not the name of the cord, the cable used is RG 58 (Sepaksi Thinnet Cables). Installation of beruntut bus topology is very simple and cheap but many can only consist of 5-7 computers.

     • Connectors BNC cable is used to connect the cable to the T connector.
     • T BNC Connectors are used to connect the cable to the computer.
     • tube BNC Connectors (BNC barrel connector) is used to connect 2
       BNC cable.
     • BNC terminator is used to marks the end of a bus topology.

"Mesh Topology"

"Mesh Topology" is a topology that was designed to have a level restoration with a variety of alternative routes or routing is usually prepared with the support of software or software.
 

"Ring topology"

"Ring topology" is called the topology of the network form series, each of which is connected to two other points, so that it can form a ring that resembles a circular path. Wires used in a ring topology BNC cable, therefore has no end it does not need a terminator. However, this topology has been widely abandoned because it has a weakness similar to a "bus topology" in addition, the development of a network using a ring topology is relatively difficult. In the ring topology all nodes / points function as repeaters which will amplify the signal along the circulation. It means every device work together to receive the signal from the previous device after it is forwarded to the device afterwards.
Excess "Topology Ring" (Ring):

• less cable.

• No data transmission will experience a collision (collision), because at one time only one node that can transmit data / data flow in one direction.

• Each computer has the right to equal access to the token sehinnga no hogging the computer network.

"Star Topology"

"Topology star" is a way to connect between one computer to another computer so as to form a network in the form of star shape (star). The star topology has the shape like a star / star, each node is connected centrally on a hardware hub or switch. Hub or switch used to connect each node in the LAN network. This tool is often used in a star topology and extended star. The only difference between Hub and Switch is the speed of data transfer. The cable used in this topology is a UTP cable with RJ-45 connectors.
The principle of a "star topology" is centralized control, all links must be through the center of the channel data to all nodes or client chooses. Central node called the primary station / server while the other is called the secondary station / client server. At the time of network connection initiated by the server, each client server can use network connections without waiting for orders from the server.
Pros: Flexible, Management and Development of the network easier, treatments performed in a node or Damage on a node does not affect other nodes, control center, ease of network management, detection and isolation of the damage / error easier.
Disadvantages: Requires special handling, centralized control (HUB) becomes a critical element.

"Bus Topology"

"Bus topology" is a topology that media transmission using a single cable or cable that connects the center of the client and the server. The both ends must be the terminator. This topology is actually quite simple and easy to handle, but at this time have many abandoned due to the density of traffic data and if there is a node that is damaged then the whole network can not function.
The following are the advantages and disadvantages of bus topology.
Advantages of bus topology:

• More Efficient cable, because the media only uses a single cable transmission and centralized so that it does not require a lot of wiring.

• Has a simple wiring layout, the installation of a bus topology wiring scheme and design that is used is very simple so installation is easier.

• Easy to develop, because the development of computer network both client and server can be done easily without disturbing the other computers. 

kinds of topology

Understanding the network topology is a technique to connect one computer to another computer that assemble into a network, where the network topology is based on the use of cost, speed of data access, the size and the level of connectivity that will affect the quality and efficiency network. 

There are a wide variety of network topology that many computers in use today include Bus Topology, Ring Topology, Star Topology, Mesh Topology, Linear Topology, each type of these topology has its own advantages and disadvantages.

"free education online"

The potential for educational applications of online learning has grown. Students are not only able to access knowledge from textbooks, but also be able to access course materials from outside the school. Teachers and students can obtain a lot of information, not limited, and can be accessed from several libraries around the world!

Students and teachers can improve classroom education by accessing information from various sources (databases, libraries, special interest groups), communicating via computer with other students or with experts in the particular field of study, and exchange information. Activities as done by national geographic allows students and teachers together to reap the benefits of connecting a national network of students, teachers, and scientists to investigate a variety of topics.
