Digital Radiography & PACS
| Question | Answer |
|---|---|
| Bus Topology | type of network setup in which each of the computers and network devices are connected to a single cable |
| Client-Based Network | is a centralized computer that controls the operations of the network,the server processes that resource as requested by the client and return only the result back to the cient |
| Coaxial Cable | network Communication medium that is similar to TV cable wiring |
| Digital Imaging & Communications in Medicine (DICOM) | a global information technology standard that allows network communication btween modality and PACS |
| Fiberoptic Cable | network communication medium that uses glass threads to transmit data on the network in the form of light |
| Health Level-7 (HL-7) | standard protocol used for medical data systems |
| Hospital Information System | information system used throughout the hospital, include direct patient care inforamtion, billing systems, and reporting system |
| Local Area Network (LAN) | Small area networked with a series of cable or wireless access points so that the computer can share information and devices on the same network |
| Mesh Topology | Network that has multiple pathway interconnecting devices and networks |
| Network | 2 or more object sharing resources and inforamtions, interconnected computer, terminals, and servers connected by communication channel sharing data and program resources |
| Network Bridge | created so that larger networks can be segmentd or broken up into smaller networks to reduce traffic within that network |
| Network Hub | central meeting point where cables from several devices can come together n share information throughout the group. simple boxlike deivce with several wires port aviable to recieve n pass on data to various pieces of equipment, |
| Network Interface Card (NIC) | interface between the computer and the network medium |
| Network Protocol | agreed on set of rules for network communication |
| Network Router | device that can read portions of the messages and direct them to their intended target, even if the device is on a seperate network and useds a different network protocol |
| Network Switch | similar to a hub but it sends data only to those devices to which the data are directed |
| Peer to Peer Switch | each computer on the network is considered equal; no computer has ultimate control over another |
| Radiology Information System | inforation system used in RT department for ordering examination and reportinf results |
| Ring Topology | network in which the devices are connected in a circle |
| Server | computer that manages resources for other computers, servers, and network devices |
| Server Based network | centerlized computer server that controls the operation, files, and sometime the programs of the computer(clients) attached to the network |
| Star Topology | network that has the devices connected to a central hub or switch |
| Thick Client | computer that can work indpendently from the network and can process and manage its own files |
| Thin Client | device that is found on a network that request services and resources from a server |
| Topology | physical geometric layout of the connected devices on a network |
| Twisted Pair Wire | network commincation medium that consists of four twised pairs of copper wire that are insulated and bundled together with a RJ-45 termination |
| Wide Area network (WAN) | network that spams a large area, city, state, nation, continent and world |
| Wireless | network commincation medium that used either infrared or radio frequencies as its mean of communication |
