Computers and other devices send information to one another. A computer acts as a ________ when it
is sending data. This same computer also acts as a receiver when the data is sent to it. Throughout the
process of information exchange, a computer may play the role of transmitter and _________many
times - Transmitter, receiver
_____________media carries information from one area to another. - transmission
_____________media consist of metal (usually copper) strands that conduct electrical impulses along a
route from one location to another. Wired media are relatively easy to install and maintain, although
installation is limited by the length of the network. They also cannot support more advanced
applications. An example of wired media would be the twisted-pair cable used in older telephone wiring
or the coaxial cabling used to connect most television sets to a cable outlet. - Wired
______________cables transmit data messages using light pulses. Fiber optic cables are more expensive
than wired media, but they permit faster and more secure transmission of data. An example of fiber-
optic media use in a network would be the fiber-optic cabling run in an office building or hospital to
create a local area network. - Fiber-optic
There is no physical conductor with _____________media. ______________ media transmit
electromagnetic waves through the air using radio waves, satellite, and microwave technology.
__________ media are used when it is impractical or impossible to set up wired or fiber-optic cables. An
example of wireless media use in a network would be a network connection to a wireless laptop or
printer. - wireless
What is a client server? - In a network, the client is the application, computer, or user that accesses
another remote computer system known as the server.
The connection between the client and server is the n______. - Network
What is the oldest and most centralized type of network configuration? Dumb terminals with no
computing ability are connected to a host, usually a mainframe computer. All computing takes place on
,the host. This type of system is used for functions such as data entry and simple queries. - terminal host
system
______________systems are similar to terminal-host systems with the client replacing the dumb
terminal. Thin clients are computers with less computing ability that rely on the server to perform
functions such as database management, printing, and application programs. Fat clients, on the other
hand, have computing power of their own and perform functions such as data processing and decision
support. Servers can be mainframes, minicomputers, or personal computers (PCs). - Client server
The function of a ______server is to provide shared disk access (for example, sharing computer files
such as documents and databases) to the workstations that are attached to a network. Each workstation
is a client device that is able to execute applications on its own. - file
____ networks are the most decentralized type of network. There is no server; each workstation
functions individually, with some shared services among the workstations. For example, one workstation
is connected to a high-speed printer, which all other workstations share. - Peer
A network__________ is the physical connection of the devices within the network. The physical
topologies are bus, ring, and star networks. - topology
A_____topology links all computers and other devices (nodes) in the network along a single line. A data
message is sent to all nodes, and only the intended recipient node pays attention to the message. A bus
topology is easy to wire and is fast. The topology is limited because of length. - Bus
_________ topology connects all the nodes in a circle, forming a closed loop. Data messages travel in
one direction around the ring. Each node re-sends the message until it reaches the intended recipient
node. The ring topology is able to operate over a larger area than a bus topology. However, it is difficult
to add new nodes to the ring. - Ring
_________ topology links all computers and peripheral devices to a central node (hub). All data
messages must pass through the hub before reaching the recipient node. The central node resends the
message. A star topology is easy to wire and repair, but if the central node goes down, the entire
network is down. - Star
_____________name refers to the top layer (level 7) of the Open Systems Interconnection model of the
International
, Standards Organization in the health environment. The standard ensures a common communication
method
between applications generally mapped through an interface. The organization's primary goal is to
provide data
exchange standards that eliminate or substantially reduce custom interface programming and program
maintenance. - HL7's
Denise works for a home health agency providing hospice care. After completing her home visits, she
returns to the office where she uploads patient data from her PDA to the agency's network.
In this particular case, Denise's PDA functions as a ________. - transmitter
What type of network topology is characterized by a central node that links to computers and other
peripheral devices, sending all data messages through the central node before reaching the recipient
node? - Star
A _______________operating system allows only one person to access the computer at a time. - single-
user
A _____________ operating system allows many people to use a computer's resources simultaneously.
An example of this type of operating system would be a client-server network configuration. Each client
is able to access the server at the same time. - multi-user
A ________________operating system has more than one central processing unit (CPU) within the
computer system. The additional CPUs may be reserved for special processing functions, such as
complex imaging in a 3D application. - multiprocessing
A ____________operating system allows a single user to have more than one software process (task)
running at the same time. Most people have this type of operating system on their desktop and laptop
computers. An example of multitasking: a user can write a note in a word-processing program while
downloading a file from the internet and printing an email message. - multitasking
A _________is an interactive system that helps managers make decisions. A decision support system is
not meant to replace the human decision-making process, but, rather, provides information to help
(support) the human decision-making process. Decision support systems are used to help solve semi-
structured and unstructured problems - decision support system (DSS)
