Computer Hardware for Hospitality Flashcards
Describe information architecture
Information architecture (IA) focuses on organizing, structuring, and labeling content in an effective and sustainable way. The goal is to help users find information and complete tasks effectively.
Backup and recovery in information architecture
are the process of making an extra copy (or multiple copies) of data. You back up data to protect it. You might need to transfer the already backed up data to your primary system or data center if you encounter an accidental deletion, database corruption, or problem with a software upgrade.
Disaster recovery in information architecture
Disaster recovery refers to the plan and processes for quickly reestablishing access to applications, data, and IT resources after a disruptive event such as power outage, equipment failure, cyber-attacks or natural disasters.
involve switching over to a redundant set of servers and storage systems until your primary data center is functional again.
Information security in information architecture
designed to protect the confidentiality, integrity and availability of computer systems and physical data from unauthorized access whether with malicious intent or not.
computer hardware used for general purpose
Desktop computers / laptops
Smartphones / tablets
gaming consoles
Computer hardware used for specific purposes
Ebook readers
digital cameras
MRI machines
Computer hardware used for input
They convert data in (binary code)
or through a telecommunications
network into a computer system
Computer hardware used for processing
Central Processing Unit (CPU) also known as
PROCESSOR, is the heart of the computer that
handles multiple tasks
This electronic chip controls all the other
hardware components and manages the applications
that run in computers
Computer hardware used for output
convert electronic data produced by the
computer system into human-intelligible form for
presentation to the end users
Computer hardware used for storage
A computer storage device is any type of hardware
that stores data.
Types of computers used today
Supercomputers
mainframe computers
midrange Computers
micro computers
Uses of supercomputers
most powerful computers. used to process huge amounts of data, model of complex processes and simulate the processes such as : Genetic Chess weather forecast
Uses of Mainframe computers
The largest type of computers used where many people in a large organization need frequent access to the same information which is organized into one or more huge databases such as Data Storage Bank Transactions Enterprise Resource Planning
Uses of mid range computers
act as servers to some networks or operate as workstations to perform
specialized high powered functions
Such as
Helps in manufacturing unibody frames, dental implants
Helps in design/ animation for movies
Uses of microcomputers/ personal computers
Least powerful / most widely used With networks, a person may access information that is stored on midrange and mainframe computers through micro computers Such as banking, airline reservations
