A cache is temporary stored data that helps software or devices access frequently used information more quickly.
Clearing a cache can sometimes help resolve certain application or website problems, although it is not a universal solution for every technical issue.
Cloud Computing
Cloud computing refers to delivering computing resources and services over a network, typically the internet.
Cloud services can provide storage, computing power, databases, software, and other resources without requiring all of the underlying infrastructure to be located on the user’s own device.
Cloud Storage
Cloud storage allows users to store files on remote servers that can be accessed through the internet.
It can be used for documents, photographs, videos, backups, and other types of digital files.
Cookies
Cookies are small pieces of information that websites can store in a user’s browser.
They can be used for purposes such as maintaining login sessions, remembering preferences, and supporting certain website functions. Some cookies may also be used for analytics or advertising-related purposes.
Cybersecurity
Cybersecurity is the practice of protecting computers, networks, applications, accounts, and data from unauthorized access, attacks, damage, or disruption.
It includes areas such as account security, network protection, malware defense, privacy, and security monitoring.
Data
Data refers to information that can be collected, stored, processed, or analyzed by people or computer systems.
Data can include text, numbers, images, audio, video, records, and many other forms of information.
Database
A database is an organized collection of information that can be stored, managed, searched, and updated.
Websites, applications, businesses, and other systems use databases to manage information efficiently.
Encryption
Encryption converts information into a form that is difficult to understand without the appropriate key or method for decrypting it.
It is widely used to protect information during storage and transmission.
Firewall
A firewall is a security system that monitors and controls certain network traffic according to defined rules.
Firewalls can help prevent unauthorized network connections and are commonly used on computers, servers, and networks.
Generative AI
Generative AI refers to AI systems capable of producing new content based on learned patterns and user instructions.
Depending on the system, generative AI can create text, images, audio, video, software code, or other outputs.
Hardware
Hardware refers to the physical components of a computer or electronic device.
Examples include processors, memory, storage drives, displays, keyboards, cameras, batteries, and circuit boards.
Hardware differs from software because software consists of digital instructions rather than physical components.
IP Address
An IP address is a numerical address associated with a device or network interface that uses Internet Protocol communication.
IP addresses allow systems to identify network destinations and communicate across networks.
Malware
Malware is a general term for malicious software designed to perform harmful or unauthorized actions.
