CIIP CORE MAIN QUESTIONS AND ANSWERS SET A+
✔✔lossless - ✔✔Used to denote a form of compression that does not degrade the
quality of the image being compressed.
✔✔lossy - ✔✔A method of compressing images which results in a slight reduction of
image quality.
✔✔MAC address - ✔✔This is a unique serial number residing in the firmware of a
network interface card that identifies the network card on the network.
✔✔Mbps - ✔✔1 million bits per second transmission rate
✔✔megabyte - ✔✔1 million bytes
✔✔Mini-PACS - ✔✔If it assumed that a PACS must be as a minimum hospital wide, a
mini-PACS can refer to a department based system, such as Radiology, A & E or
Orthopaedics, or to a modality based system such as CT and MRI or CR.
✔✔modem - ✔✔A piece of hardware that lets a computer talk to another computer over
a phone line
✔✔MRN - ✔✔see 'patient ID'
✔✔Network Attached Storage (NAS) - ✔✔This is a device that contains a number of
disk units attached to a dedicated server. The NAS device appears as a server on the
network.
✔✔Network Interface Card (NIC) - ✔✔This is a circuit board that allows a computer to
communicate on the network. There are NICs available for all network protocols.
✔✔Network Operating System (NOS) - ✔✔The software that connects all the devices
on a network so that resources can be shared efficiently and files can be transferred. It
, handles administration of all network functions, Network operating systems are usually
in two parts; server and client/requester.
✔✔node - ✔✔A node can be a computer or some other device, such as a printer
attached to a network. Every node has a unique network address, known as a Media
Access Control (MAC) address.
✔✔octet - ✔✔One of the four number groups in an IP address. Although it is three
decimal digits, it is derived from an eight-digit binary number, hence the term 'octet'.
✔✔Open Database Connectivity (ODBC) - ✔✔A standard database access method
developed by Microsoft™. ODBC should make it possible to access any data from any
application regardless which DBMS is handling the data. ODBC manages this by
inserting a middle layer between the application and the DBMS.
✔✔Open Systems Interconnection (OSI) model - ✔✔A framework developed by the
International Standards Organization (ISO) to provide worldwide standards for computer
communications.
✔✔operating system (OS) - ✔✔The software used to control the computer. There are
several different operating systems used, the choice depending on the function and
power needed.
✔✔packet - ✔✔Data sent over a LAN is separated into blocks known as packets to
create optimum transfer over a packet-switching network. One of the key features of a
packet is that it contains the destination address in addition to the data.
✔✔Packet Internet Groper (PING) - ✔✔A program used to test whether a particular
network destination is online, by sending an Internet control message protocol (ICMP)
echo request and waiting for a response.
✔✔PACS - ✔✔Picture Archiving and Communication System. A system (often
comprised of several components) concerned with digital storage, transmission, and
display of medical images.
✔✔patient ID - ✔✔A hospital-wide unique identifier for a patient.
✔✔pixel - ✔✔This is a word defined from the term "picture element" and is the smallest
viewable element, rectangular or square in an image or display. The function of a
workstation will determine the number of pixels required in its display.
✔✔port number - ✔✔In computing, a port (derived from seaport) is usually an interface
through which data are sent and received.
✔✔lossless - ✔✔Used to denote a form of compression that does not degrade the
quality of the image being compressed.
✔✔lossy - ✔✔A method of compressing images which results in a slight reduction of
image quality.
