LO1—Understand Computer Hardware Components Flashcards
Computer hardware
Physical components of a computer
Computer components
Internal or built in elements that allow the computer to run (processors, storage, power supply)
Icon
A symbol/image on a computer screen
Input device
A device (which may be another computer) which allows the user to give instructions or provide data to the computer system
Output Device
A device that enables the computer system to provide information, data or instructions to another user (which may be human or another user)
Storage device
Any hardware capable of storing information temporarily or permanently
Change management
A systematic approach to dealing with the transition or transformation of an organisation’s goals, processes or technologies. The purpose of change management is to implement strategies for effecting change, controlling change and helping people to adapt to change
Hybrid cloud
A cloud computing environment which uses a mix of on-premises, private cloud and public cloud services with orchestration between the two platforms. By allowing workloads to move between private and public clouds as computing needs and costs change, hybrid cloud gives businesses greater flexibility and more data deployment options
Hypervisor
A hardware virtualisation technique that allows multiple guest operating systems (OS) to run on a single host system at the same time. The guest OS shares the hardware of the host computer, such that each OS appears to have its own processor, memory and other hardware resources. A hypervisor is also known as a Virtual Machine Manager (VMM).
Internet of Things (IoT)
A computing concept that describes a future where everyday physical objects will be connected to the Internet and be able to identify themselves to other devices
Privacy Filter
A panel or filter that is placed over a display to make it difficult or impossible for someone to see the screen without being directly in front of the display
Radio Frequency Identification (RFID)
A system used to track objects, people, or animals using tags that respond to radio waves. RFID tags are integrated circuits that include a small antenna. They are typically small enough that they are not easily noticeable and therefore can be placed on many types of objects
Social Engineering
A non-technical method of intrusion used by hackers that relies heavily on human interaction and often involves tricking people into breaking normal security procedures
VoIP
A technology that allows telephone calls to be made over computer networks like the Internet
Central processing Unit (CPU)
The unit that controls the actions of the computer system and manipulates the data required for particular tasks
