Y12 Hardware Flashcards
(43 cards)
Hardware
physical components of computer
CPU
the brains of the computer. performs the bulk of processing and calculations required by the computer’s software. It executes instructions stored in memory, and performs arithmetic and logical operations.
Motherboard
main circuit board of a computer and connects all components, allowing them to communicate with one another
Power supply
converts AC power from wall outlet into DC power that computers components can use. It provides necessary voltage and current.
Display
Output device that visually presents information processed by a computer. It converts digital signals into a visual format.
RAM
(random access memory) is a type of volatile memory that temporarily stores data and instructions which the CPU needs to access quickly.
GPU
(graphics processing unit) is a processor designed to handle complex mathematical calculations required to render graphics and images
Computer system
set of integrated components that work together to perform computing tasks. it consists of hardware and software that collaborate to accept inputs, process data, store information and produce outputs.
HDD
hard disk drive is a traditional storage device which uses spinning disks to read and write data. It is also non-volatile, meaning the data is always stored on there.
SSD
solid state drive is a storage device which uses flash memory to store data. It is faster and more reliable than HDD but is smaller
Form factor
the size, configuration, shape, weight, or physical arrangement of a device
GPS
global positioning system is a satellite based navigation system that provides location and time information
NFC
near field communication is short-range wireless technology that enables communication between devices when brought closer
AR
argumented reality is technology that overlays digital content onto the real world through device’s camera and screen. ar is transforming how users interact with their mobile devices. it provides users with immersive experiences that overlay digital information into real world, like enhancing location-specific information, home design and visualisation and integration with AI
VR
virtual reality is technology that creates immersive, computer generated environment that can be experienced through special headsets. it has made significant strides, offering users fully immersive experiences, such as cordless headsets, diverse applications and improved realism
operating systems
software that manages hardware resources and provides services for programs
resolution
number of pixels displayed on a screen, expressed as width x height
secondary storage
non-volatile storage used for long-term data retention
WIFI
wireless networking technology that allows devices to connect to the internet
Bluetooth
wireless technology standard for exchanging data over short distances
explain about convergence
- merging of different technologies or media platforms into unified systems or devices.
- why is it important
-> improvements of technology are introduced
-> digital cameras used to be popular, but most people use their phones
-> results in easier access to technology at a lower cost, like wifi
mobile device
portable computing device that is small enough to operate in one hand, typically having a display screen, internet and applications, and designed for mobility and flexibility
software
programs that run on a computer
specification
detailed description of design and capabilities of a device, includes components like processor speed, storage capacity, memory etc.
