Analog - CORRECT ANSWER✅✅✅A continuous signal where the time varying variable is represented
by another time varying quantity. It differs from a digital signal where a continuous quantity is
represented by a discrete function that only takes on one of a finite number of values.
Application Service Provider (ASP) - CORRECT ANSWER✅✅✅An ASP hosts a variety of applications
on a central server. For a fee, customers can access the applications over secure Internet connections or
a private network. This means that they do not need to purchase, install or maintain the software
themselves; instead they rent the applications they need from the ASP. New releases, such as software
upgrades, are generally included in the price.
Asynchronous - CORRECT ANSWER✅✅✅Term describing store and forward transmission of medical
images and/or data because the data transfer takes place over a period of time, and typically in separate
time frames. The transmission typically does not take place simultaneously. This is the opposite of
synchronous (see below).
Asynchronous Transfer Mode (ATM) - CORRECT ANSWER✅✅✅A telecommunications standard to
support voice, video and data communications. The mode uses asynchronous time-division multiplexing
and encodes data into small, fixed-sized cells rather than packets or frames.
,Authentication - CORRECT ANSWER✅✅✅A method of verifying the identity of a person sending or
receiving information using passwords, keys and other automated identifiers.
Bandwidth - CORRECT ANSWER✅✅✅A measure of the information carrying capacity of a
communications channel; a practical limit to the size, cost, and capability of a telemedicine service.
Basic Rate Interface - CORRECT ANSWER✅✅✅An ISDN (see below) configuration that provides two
bearer (B) channels at 64 kilobits/second (kbit/s) each and one data (D) channel at 16 kbit/s. B channels
are for voice data and D channels for any combination of data, control/signaling, and X.25 packet
networking. B channels can be aggregated to provide128 kbit/s.
Bits Per Second (bps) - CORRECT ANSWER✅✅✅Number of electronic data bits conveyed or
processed per unit of time.
Bluetooth Wireless - CORRECT ANSWER✅✅✅An industrial specification for wireless personal area
networks (PANs) that provides the means to connect and exchange information between devices such
as mobile phones, laptops, PCs, printers, digital cameras and video game consoles over a secure, globally
unlicensed short-range radio frequency. The specifications are developed and licensed by the Bluetooth
Special Interest Group (http://www.bluetooth.com/Pages/about-bluetooth-sig.aspx).
Bridge - CORRECT ANSWER✅✅✅Device for linking multiple videoconferencing sites in a single
videoconference session. It is also often referred to as a multipoint control unit (MCU).
Broadband - CORRECT ANSWER✅✅✅Communications (e.g., broadcast television, microwave, and
satellite) capable of carrying a wide range of frequencies; refers to transmission of signals in a
frequency-modulated fashion over a segment of the total bandwidth available, thereby permitting
simultaneous transmission of several messages.
Cascading - CORRECT ANSWER✅✅✅Means to accommodate more videoconference participants
than using one MCU by joining another MCU into a session hosted by the primary MCU.
Certification Commission for Health Information Technology (CCHIT) - CORRECT
ANSWER✅✅✅Founded in 2004 with the public mission of accelerating the adoption of health IT, it
,certifies electronic health records (EHRs) using comprehensive, practical definitions of what capabilities
were needed in these systems. (http://www.cchit.org/)
Centers for Medicare & Medicaid Services (CMS) - CORRECT ANSWER✅✅✅A federal agency within
the United States Department of Health and Human Services (DHHS) that administers the Medicare
program and works in partnership with state governments to administer Medicaid, the State Children's
Health Insurance Program (SCHIP), and Health Insurance Portability and Accountability Act (HIPAA)
standards. (Wikipedia)
Channel Service Unit/Data Service Unit (CSU/DSU) - CORRECT ANSWER✅✅✅A digital-interface
device for connecting Data Terminal Equipment devices (DTE) (e.g., router) to a digital circuit (e.g., T1
line). CSU connects to the network and the DSU handles the DTE interface.
Circuit Switched Network - CORRECT ANSWER✅✅✅A method for implementing a
telecommunications network where two nodes have a dedicated communications channel through the
network for communication, guaranteeing full bandwidth for the session.
Class of Service (CoS) - CORRECT ANSWER✅✅✅Used in data and voice protocols to differentiate
payloads in the transmitted packets to help assign priorities to the data payload.
Clinical Decision Support System (CCDS) - CORRECT ANSWER✅✅✅Systems (usually electronically
based and interactive) that provide clinicians, staff, patients, and other individuals with knowledge and
person-specific information, intelligently filtered and presented at appropriate times, to enhance health
and health care. (http://healthit.ahrq.gov/images/jun09cdsreview/09_0069_ef.html)
Clinical Information System - CORRECT ANSWER✅✅✅Hospital-based information system designed
to collect and organize data relating exclusively to information regarding the care of a patient rather
than administrative data. .
Cloud computing - CORRECT ANSWER✅✅✅The use of computing resources (hardware and
software) that are delivered as a service over a network (typically the Internet). The name comes from
the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system
diagrams. Cloud computing entrusts remote services with a user's data, software and computation.

, CODEC - CORRECT ANSWER✅✅✅Acronym for coder-decoder. This is the videoconferencing device
that converts analog video and audio signals to digital video and audio code and vice versa. CODECs
typically compress the digital code to conserve bandwidth on a telecommunications path.
Compressed video - CORRECT ANSWER✅✅✅Video images that have been encoded using fewer bits
of information than the original dataset (either lossless or lossy) to reduce the amount of bandwidth
needed to capture the necessary information so that the information can be sent over a network.
Computer-based Patient Record (CPR) - CORRECT ANSWER✅✅✅An electronic form of individual
patient information designed to provide access to complete and accurate patient data.
Data Compression - CORRECT ANSWER✅✅✅A method to reduce the volume of data using encoding
that results in the data having fewer bits of information than the original dataset (either lossless or
lossy) to reduce image processing, transmission times, bandwidth requirements, and storage
requirements. Some compression techniques result in the loss of some information while others do not,
which may or may not be clinically important.
Diagnostic Equipment (Scopes, Cameras and Other Peripheral Devices) - CORRECT ANSWER✅✅✅A
piece of hardware or device not part of the central computer (e.g., digitizers, stethoscope, or camera)
