CIIP ACTUAL FINALS QUESTIONS AND ANSWERS
SET A+
✔✔Secure Socket Layer (SSL) - ✔✔Secure Sockets Layer. A protocol from Netscape
Communications Corporation, which is designed to provide secure communications on
the Internet.
✔✔segment - ✔✔The separation of an image into meaningful components. In most
medical application, this refers to an anatomic structure (e.g. a blood vessel, bone, lung)
or a disease process (e.g. a tumor)
✔✔server - ✔✔A computer which controls the function of network resources. A server is
often applied to a dedicated task, e.g. a file server controls delivery of files and a
network server controls network traffic. However it is possible for servers to fulfil more
than one task if they have a multiprocessing operating systems.
✔✔Service Class Provider (SCP) - ✔✔This is a DICOM term. A Service Class Provider
acts as a server and provides a service to a client or user, where the client is a
workstation or modality that requires information from the server. An example of this is
an archiving device which acts as a service class provider (SCP) when receiving
images from a modality (which acts as a servive class user (SCU)).
✔✔Service Class User (SCU) - ✔✔This is a DICOM term. A Service Class User is a
'client', where a client is a workstation or modality, and hence uses a service provided
by the SCP. An example of this is the a modality (which acts as a service class user
(SCU) when sending images to an archiving device (which acts as a service class
provider (SCP)).
✔✔Small Computer System Interface (SCSI) - ✔✔A parallel interface that provides fast
data transmission.
✔✔sniffer - ✔✔sniffer
, ✔✔socket - ✔✔The combination of an IP address and a port number.
✔✔Storage Area Network (SAN) - ✔✔A network topology which has a series of servers
linked through a series of switches through a dedicated network to a central storage.
This allows all servers to access a large storage and improves access times. This
topology would be most suitable in a distributed PACS, with the PACS servers at
remote locations accessing a central data store. A dedicated high speed network,
usually fibre channel connects the storage elements (RAID, JBOD and tape), to the
servers.
✔✔Structured Query Language (SQL) - ✔✔The high level language used to query
databases and obtain information.
✔✔subnet - ✔✔An interconnected, but independent segment of a network that is
identified by its Internet Protocol (IP) address.
✔✔switch - ✔✔A device that filters and forwards packets between LAN segments.
Switches, because of their design, support any packet protocol.
✔✔thumbnail - ✔✔A low resolution, small size version of an image which can be used
to quickly select the full size image.
✔✔Transmission Control Protocol/Internet Connection Protocol (TCP/IP) - ✔✔A
protocol for communication between computers, used as a standard for transmitting
data over networks and as the basis for standard Internet protocols.
✔✔Transmission Control Protocol/Internet Protocol (TCP/IP) - ✔✔TCP is one of the
main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets,
TCP enables two hosts to establish a connection and exchange streams of data. TCP
guarantees delivery of data and also guarantees that packets will be delivered in the
same order in which they were sent.
✔✔trojan - ✔✔a program that appears desirable but actually contains something
harmful
✔✔Uniform Naming Convention (UNC) - ✔✔paths simply specify the name of a
particular computer and a particular directory or resource to be accessed. The name of
the computer is prefaced with two backslashes, while the directory is prefaced for the
traditional one backslash. For example, \\UTC_SRV1\VOL1.
✔✔Uninterruptible Power Supply (UPS) - ✔✔A device which provides back-up power in
the event of failure in the primary power supply system. If there is a power-cut or drop-
out the UPS will keep the system running for a finite period of time, allowing the primary
power supply to be repaired and/or the system to be powered-off gracefully. This
protects the equipment and the stored data.
