CHAPTER I Flashcards
4 major components of Internet of Things:
*Sensors
*Gateway
*Cloud/Server
*Mobile Application
Gather minute data from the surrounding environment. It allows an IoT device to capture relevant data for real time or post-processing
Sensors
senses and measures the temperature and converts it into an electric signal
DHT 11 Temperature humidity sensor
able to detect the presence of nearby objects without any physical contact
Si114x and Si1102
detects smoke and its level of attainment
smoke sensors
what are examples of microcontrollers?
*Arduino uno R3
*Raspberry Pi
The technology being used to aid the people with special needs.
Assistive Technology
Used to control a windows computer with your eyes.
PCEeye
is used to rejuvenate dormant circuits in patients whose spinal breaks are not complete
Electrical Stimulation
who designed the Helmet for the Blind
Chinese organization CloudMinds
Meta looks like a cycling helmet and uses sensors and cameras to map its surroundings.
Helmet for the Blind
Monitors the brain activity of users to identify which voice the listener is focusing on.
Next-generation hearing aid
Designed to help those with paralysis to stand and walk.
Bionic Exoskeleton
is a collection of entities that are designed to receive, process, manage and present information in a meaningful format.
Computer System
It refers to the physical components that make up a computer system
Computer Hardware
What are the four categories of Computer Hardware:
*Input Devices
*Processing Devices
*Output Devices
*Storage Devices
Components which are used to input raw data care categorized under?
Input Devices
It is the stage where raw data is transformed into information.
Processing Devices
Components that manipulate data into information are categorized under?
processing
It is the major device the category of processing
Microprocessor
The microprocessor is subdivided into three important units:
*The control unit
*Arithmetic and logic unit
*Register and cache
It manages and supervises the operations of the processor and other components that are crucial in data manipulation.
The control unit
is responsible for all arithmetic and logic operations like addition, multiplication, division, and comparison logic operations.
Arithmetic and Logic unit
These are storage locations inside the processor that respond to the instructions of the control unit.
Register and Cache
Hardware components that disseminate and display both data and information are classified under the
Output category
For disseminating date and information.
Output Devices
Components that retain/store data are classified under?
memory/storage devices
storage is sub-divided under?
primary and secondary memory
usually refers to random-access memory but can also refer to all memory that works in tandem with the processor.
Primary Memory
also known as “storage” refers to a location where information that are saved non-volatile.
Secondary memory
is where all the information and settings for the motherboard are stored.
BIOS or Basic Input Output System
is what’s responsible for keeping all the information intact when the entire system is shut down.
CMOS or Complementary Metal Oxide Semi-Conductor Battery
Are located at the back of the computer and are often color-coded.
Input/Output Ports
Has 20 or 24-pin female connectors.
ATX (Advanced Technology eXtended) connector
This is the largest connector on the motherboard, as this draws out the needed power directly from the power supply.
ATX (Advanced Technology eXtended) connector
This is where you connect the Power switch, LED power indicator, Reset switch, and the HDD LED cables.
Front I/O Connectors
it is where your CPU is installed.
CPU socket
This is where the processing and transfer of data happens.
CPU Socket
where you add extra components such as a video card, network card, audio card, or PCle SSD.
Expansion Card Slots
It is where you put the Network Interface Card (NIC)
Network Card Slot
This is where you connect your network card so you can connect to the internet through the telephone line..
Modem Card Slot
is where you place the RAM modules.
RAM (memory) slots
only supports a 32-bit bus
SIMM slot (Single in-line memory module)
can simultaneously run with a 64-bit bus
DIMM slot (dual inline memory module)
