☑️mouse, keyboard, monitor, speaker, microphone, printer, etc.
OPERATING SYSTEM -
☑️instructions that a computer follows come from software. A basic software
environment is established by the computer's (OS)
RAM -
☑️Random access memory which converts a series of instructions
CPU: -
☑️Central Processing Unit that receives each instruction or data file from memory and
processes it
STORAGE -
☑️data written into different types of storage devices like a hard drive or optical discs
MAINFRAME -
☑️a large high speed workstation and the primary memory of a computer
WORKSTATION -
☑️a type of pc housed in a case that can sit on or under a desk
MOTHERBOARD -
☑️where the pc's components are attached to and contained within a computer's case
SERVER -
☑️any computer providing services to other computers, implies a powerful computer that
supports a number of users simultaneously in a computer network
FAULT TOLERANT -
☑️in order for a server to be reliable it needs to starting specifying high quality
components and also by using extra copies of components for redundancy
POWER SOURCE -
☑️portable computers can be run from internal battery packs as well as from building
power
NETWORKING -
1
, ☑️portable computers use wireless radio technologies to connect to networks rather than
cabled connections
INTERNET OF THINGS (OIT) DEVICES -
☑️refers to a world in which many different types of things are embedded with
processing and networking functionality
OEM -
☑️pc and laptop companies producing these are referred to this because rather than
making each component that goes into a pc, they source components such as cpu's and RAM
modules from manufactures and put them together as a branded PC system. Original Equipment
Manufacture.
MEDICAL DEVICES -
☑️represents another class of devices where use if electronics to remotely monitor and
configure that appliance is expanding rapidly. Ex: cardiac monitors, defibrillators, insulin pumps
GAMING CONSOLE -
☑️have powerful cpus and graphics processors, plus Ethernet and WiFi for wired and
wireless home networking and internet connectivity.
INPUT DEVICE -
☑️the computer receives data entered by the user through peripheral devices like mice,
keyboards, scanners, cameras and microphones
OUTPUT DEVICE -
☑️the processed data is shown or played to the user through an output device like a
monitor or loudspeaker system
ALT+F4 -
☑️to close a tab
TOUCHPAD -
☑️the mouse build in to the laptop
TASKBAR -
☑️opening programs easier for your favorite or mainly used programs which is located at
the bottom of the screen.
NOTIFICATION AREA -
☑️usually on the right side of the screen notifying you about what you want like an alarm
or an update on a program, etc.
POST -
☑️Power-On Self-Test which starts right before the Windows loading screen pops up
when you turn on the computer
RSI -
☑️Repetitive Strain Injury which occurs usually when you're working on a task or even
playing games for long period of time
