1. Local area network (LAN) 2. Wide area network (WAN)

A network can be classified into two main major geographic categories. These two are:

health level 7 (HL-7)

A standard that oversees most computerized clinical and administrative data such as demographics, reports, claims, and orders. Developed by American National Standards Institute (SDO) and Accredited Standards Developing Organizations (ANSI)

1985

First version completed of Digital Imaging Communications in Medicine (DICOM) in what year? pp. 108 to 111 (to finish reading)

1. Peer to peer 2. Server or Client based (server)

In Component Role Classification: Network are typically classified as either ------ or -------

Client-Based Network

Is similar to a server-based network; however, rather than sending the entire original resource to the client for processing, the server processes the resource as requested by the client and returns only the results back to the client. This smaller exchange of information lessens the load on the network and allows more room for another request.

Network bridge

It can also bring two or more networks together that speak the same language

Network hub

It does not know what the data are, nor to which device they should go, so it simply forwards the bits. It has several wiring ports available on it to receive and transmit data to the various connected pieces of equipment.

Mesh topology

Mesh topology The Internet is based on ------ , and this topology is used most often to connect networks to other networks.

Mesh topology

Mesh topology is a network that has multiple pathways interconnecting devices and networks. This type of network has redundancy built in with the multiple connections.

Ring Topology

One of the four common network topology configurations type: is a network in which the devices are connected in a circle. Each device passes its received messages to the next node on the ring (always in the same direction), and the data transmissions move around the circle until they reach the correct receiver. If there is a break at some point in the ring, the entire network comes to a halt. pp. 107-108 (unfinished)

Star Topology

One of the four common network topology configurations type: is a network that has the devices connected to a central hub or switch.

Star Topology

One of the four common network topology configurations type: It can be thought of as a bus topology with the bus collapsed into a central box: the hub or switch.

Star Topology

One of the four common network topology configurations type: Which The data are sent through the hub out to the destination device. This transmission of data may be through another hub or switch to an adjacent network or directly to the device.

Bus Topology

One of the four common network topology configurations type: is a network in which all devices are physically attached to and listen for communication on a single wire. it has a single point of failure (one wire). Example: If a wire is break, the entire network is down.

Network bridge

is created so that larger networks can be segmented or broken up into smaller networks to reduce traffic within that network. With that said, the segmented information can be connected to the bridge
