Q

software: operating system

A

windows, mac OS, android, iOS etc

executes application programs

manages resources

  • for sharing internal memory and processor(s)
  • handles I/O devices
  • manages space on external storage devices
22
Q

software: other software that runs on top of the OS

A

developmental; application; communications

microsoft powerpoint, iTunes etc

23
Q

look at the brainrot on slide 17

A

24
Q

Networking kroll scenario

A

RPh on PMS sends info to network that sends info to insurance server when filling out pateitn insurance info

25
Q

networking 101: telecommunications link

A

how devices communicate

ex. modems, ethernet cables, fiber optic cables, radio for satelites

26
Q

networking 101: modems

A

allow you to connect to the internet through your ISP

-A modem connects home network (LAN) to you ISP’s network (WAN) to get the internet

27
Q

networking 101: routers

A

create networks by allowing greater than or equal to 2 computers and the modem to connect

ex. it takes the signal from your modem and routes it to your devices

think wireless routers

ex. your computer connects to your wireless printer using a router

28
Q

networking 101: hosts

A

computers connected to networks

-smartphones, laptoms, iPads, etc

29
Q

networking 101: clients

A

computers or programs that connect to a network and retrieve data

30
Q

networking 101: servers

A

provide services for clients

ex. email servers, database servers, game servers

31
Q

networking 101: nodes

A

any device that is attached to a network and transmits, receives, or forwards info

  • nodes can be clients and servers
  • includes hosts linked by modems, routers, etc
32
Q

LAN

  • what is
  • what are 2 types of connection
  • what require
  • what may include to connect to other networks
A

local area network

  • connects computers within a small building
  • may be wired (via network cables, often running ethernet protocol) or wireless
  • requires network interface card
  • may include a router to connect to other networks
33
Q

WAN

A

Wide area network

  • connects computers far away
  • requires host computers for network and communications management
34
Q

TCP/IP

A

transmission control protocol/internet protocol

  • standard procedures for adressing and transmitting messages
  • messages broken into data packets at source
  • analogy: cut letter into pieves and put ea frament in its own envelope
  • packets are routed independentyl
  • packets are re-assembled into message at end
35
Q

IP addresses: what are they

A

-unique ID for every computer (host) on a network (WAN, LAN, internet)

36
Q

IP addresses: how allocate

A

-hierarchical allocation of addresses

37
Q

IP addresses: DNS

A

server for Domain Name System (DNS) consults registry to translate host names to corresponding IP adresses

38
Q

HTTP

  • what is
  • how used
  • client/server model
A

hyper text transfer protocol

  • communication protocol between clients and servers
  • utilized TCP to transfer information between computers

client
- browser that requests, receives, displays

server
-receives requests and responds to them

39
Q

Networking and security: firewalls

A

barriers between trusted networks (your home) and untrusted networks (the internet)

  • built into routers
  • can be added as antivirus software
40
Q

Even with firewalls what is most important thing for security

A

not connect with untrusted sources

41
Q

Networking and security: VPN

A

virtual private network
-allows remote users on the WAN to access a LAN

  • essentially a secure tunnel
  • how access the virtual lab computer off campus or patient records from home

-need to act act at home as you would in the hospital when you are on a VPN
+ do not leave screens open, do not show ppl records, do not talk about the records in a public space

42
Q

Authentication 101: something you know

A

password, PIN, pattern

43
Q

Authentication 101: something you have

A

smartwatch to open smartphone, FOB

44
Q

Authentication 101: something you are

A

fingerprint, iris

45
Q

Authentication 101: what type authentication HC use

A

HC typically prefers multifactor authentication (greater than or equal to 2 options)

ex. FOB + password
ex. smartwatch + fingerprint

46
Q

encryption 101

  • what is
  • role of sender and receiver
  • VPN
A

encryption is process of mathematically converting info to render it unintelligible without a key to decode it

  • sender uses algorithm to encode info and receiver uses same algorithm to decode
  • how VPN creates a secure tunnel
47
Q

examples of encryptions

A

caeser cipher

german enigma machine

48
Q

HTTPS

A

HTTPS = HTTP + Security

provides data encryption and server authentication

49
Q

slide 30 photo on how client requests https session

A

50
Q

HL7

  • what is
  • stds for what
  • how message
A

international standard to allow the exchange integration sharing and retrieval of electronic health information

provide messaging standard of certain common communication
-medication dispense, medication request

HL7 message can be transferred through HTTPS to provide communication between different systems (ex. EMR/EHR/PMS)
