Hardware Device Selection Flashcards
Information systems dedicated to medical facilities are known as
Hospital Information Systems (HIS)
There are three broad types of HIS
administrative, semi- clinical, and clinical
handle non-medical management issues such as payroll.
Administrative
Tracks the flow of patients into and out of the hospital.
Semi-clinical
Performs order-entry results reporting.
Semi- clinical
information is entered directly into the system at the patient’s bedside rather than having the information transcribed from written notes.
Point of service (POS)
there are many systems currently available that support healthcare facility issues such as laboratory, pharmacy, and radiology.
Specialty Support Programs
The following are the major internal types of hardware of all computers:
Motherboard
Central processing unit (CPU)
Control units
usually housed inside a plastic case, but there may be components that exist outside of the case.
hardware
usually houses the motherboard, microchips, processors, and electronic circuits that carry out the computer’s primary functions.
Computer case
a thin piece of non-conducting plastic onto which the computer’s circuits are printed.
motherboard
has areas where chips are mounted and slots are placed which allow the addition of other pieces of hardware.
motherboard
comprised of different unit types: arithmetic, logic, control, and memory.
Central processing unit (CPU)
perform fetch, execute, decode, and store functions based on the computer’s machine language.
control units
This term encompasses the hardware that is connected to the computer to make it fully functional.
peripherals
include the keyboard, printer, monitor, storage devices, and mouse.
peripherals
include disk drives, hard drives, and USB drives.
storage devices
There are three major classes of computers:
Analog, Digital, and hybrid
measure specific continuous data and do not break the information down any further.
Analog
measure temperature, pressure, heart rate, voltage, or current.
Analog
use binary code to represent data.
Digital computers
This is the most common type of computer used at home and in businesses
Digital computers
have elements of both analog and digital computers.
Hybrid
These computers are produced and used for highly specific tasks which are often based on physics and engineering.
Hybrid
The most common network interface card (NIC) is called an
ethernet card
is installed onto a networked computer and allows full time access to the local area network (LAN).
