Open Systems Interconnection (OSI) model

in the late 1970S, the Open System Interconection (OSI) referenced model was created by International Organization for Standardization (ISO) to break networking of an computer that could tipically comunicate only with computers from the same manufacture.

The Open System Interconnection (OSI) Model is a the primary architectural model for networks. It describe how data and networks information are communicated from application on another application on one computer through the network media to an application on another computer.

The advantages of using the OSI layer model:

1. It divides the network communication process into smaller and simpler components, thus aiding component development, design and troubelshooting.
2. It allows multiple-vendor development through standardization of networks components.
3. It encourages industry standardization by defining what functions occur at each layer of the model
4. It allow various types of networks hardware and software to communicate.
5. It prevents changes in one layer from affecting other layer, so it does nit hamper development

One of the best functions of the OSI specifications is to assist in data transfer between disparate hosts / vendor. The OSI isn't a physical model, but it's a set of guidelines that application developers can use to create and implement applications that run on a network. It also provides a framework for creating and implementing networking standards, devices, and internetworking schemes.

The Open Systems Interconnection (OSI) model has seven different layers, and divide into two groups:

• The top three layer (upper layer) 'define how' the application within the end stations will communicate with each other and with user. so, upper layer is responsible for application communicating between hosts. none of upper layer knows anything about networking of network address.
  
• The bottom four layer (bottom layer) 'define how' data is transmitted end to end, how data is transferred through a physical wire or through switches and routers. The bottom layers also determine how to rebuild a data stream from a transmitting host to a destination host's application.

Network devices is operate at all seven layers of the OSI model:

• Network management stations (NMSs)
• Web and application servers
• Gateway (not default gateways)
• Networks host

 The OSI reference model has seven layers:

• Application layer (layer 7)
• Presentation layer (layer 6)
• Session layer (layer 5)
• Transport layer (layer 4)
• Network layer (layer 3)
• Data link layer (layer 2)
• physical layer (layer 1)

bridges, switches, hubs, and router

Hubs don’t segment a network. They just connect network segments together. So, ‘materi kuliah’ don’t allow of you use a hub in a big network.

How about router? Router can connect networks together and route packets of data from one network to another. Routers, by default, break up a broadcast domain and set all of devices on a networking segmen.

Routers can also provide packet filtering by using access lists, and when routers connect two or more networks together and use logical addressing (IP or IPv6), this called an internetwork. Last, routers use a routing table (map of internetwork) to make path selections and to forward packets to remote networks.

switches aren’t use to create internetworks and switches do not break up broadcast domains by default, switches have functionality to a network LAN. The main purpose of a switch is to make a LAN works better to optimize its performance. Providing more bandwidth for the LAN users, switch don’t forward packets to another networks as routers do. Instead, they only “switch” frames from one port to another within the switched network.

Bridges and switches???

Basicly bridge and switches do the same thing, break up the collision domain on a LAN. but its differences:

• Bridge in a network to reduce collisions within broadcast domains and to increase the number of collision domains in network.
• Bridge was used to connect the hubs to a router. The bridge breaks up collision domains, but all the hosts connected to both hubs are still crammed into the same broadcast domain.
• The bridge only created two collision domains, so each device connected to a hub is in collision domain as every other device connected to that same hub. This is actually pretty lame, but it’s still better than having one collision domain for all hosts.
