left over CMAP Flashcards
Iaas
Infrastructure as a service. provisioning of hardware resources quickly
SaaS
software as a service: accessing software resources from third parts when not obtaining a license. Spotify?
PaaS
Platform as a Service; mix of IaaS and SaaS: provisioning some hardware like storage and servers, then a multi tier web based application/database platform
DaaS
Desktop as a service: provisioning a desktop (virtual desktop - VDI) via the cloud and can lock it down to refresh images.
File sychonization
Access to files when no network connection present
shared services
pooled resources where the hardware making the cloud providers data center is not dedicated or reserved to an individual client.
contract level of service equal to 5-nines
is 99.999% availability and minimal downtime.
VDI
virtual desktop infrastructure using virtual machine to provision desktop machines,
cross platform virtualization
testing environment to test software with different OS and resource constraints.
client-side virtualization
used on a guest OS to run regular desktops while supporting legacy software and OS used to test and develop application
testing and development
using a VM and a guest OS hypervisor to ensure is running as expected
intermittent shutdown
pc powering off repeatedly during use.
limited connective message in windows
can establish a physical connection to the network, but cannot receive a lease from the DHCP server.
IOPS
input/output performance measurement. for HDD, SSD, SAN. the higher the better the performance indicator but bench markers are set by manufacture.
What does SMART do
alert OS when it detect failure and run test to detect damage of storage devices and repair most disks but maybe not corrupt OS. Can also run self-diagnostics to determine performance issues.
adaptive brightness
automatically changing brightness
calibrating a display occurs in ..
color management applet
stuck pixel
a pixel the holds its bright color. a utility to cycle through extreme color gradients can resolve this
what is is considered tooo hot for a phone
40 degrees C
case standards IPX IP5/6 - 7/8
first number indicates solid repelling 5/6: 5 = protection, 6 = proof - if first is X, this means its not solid repelling; second digit implies liquid resistance. 8 is good submersion greater then 1m.
NFC
near-filed communication
active sync
legacy technology allowing older mobile devices to connect to a mail server
dialing 228
can trigger an update in the preferred roaming list and what are the needs to connect to the carrier’s network.
serial interface card
legacy interface one of the oldest and devices like matrix printer might use it in order to connect to pc.
VA monitor
tilted crystals - best for contrast-ratio but lower performance than TN and wide color gamut for mid-range
IPS monitor
in-plane switching - rotating crystals, provides better color for a wide range of angles. balanced performance and quality
OLED monitor
thinner, lighter, consumes less power, and offers better color contrasts
TN monitor
twisted nematic - twisted crystals, best for budget
inverter
converted DC to AC
Wan SOHO router interface requires a public address
ONT
optical network terminal: converts light signals into electrical ones.
802.3
ethernet standard utilizing fiber and copper wires for LAN.
802.11
802.11 is wireless LAN. wireless-only configured networks connect in infrastructure mode
Supplicant
devices that request access from AAA server.
Gain
the amount of boost that occurs in a focused antenna measured in dBi
LDAP
lightweight directory access protocol:
