PTE Academic Listening Technology and Computing Terms Quiz

API stands for Application Programming Interface, which is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information, facilitating integration and functionality between different systems and services.

A firewall acts as a barrier between a trusted internal network and untrusted external networks. It monitors and controls incoming and outgoing network traffic based on predetermined security rules, preventing unauthorized access and protecting against malicious software. By filtering data packets, it helps maintain the integrity and security of a computer system.

Bandwidth in networking refers to the maximum data transfer rate of a network connection. It indicates how much data can be sent or received in a given time period, typically measured in bits per second (bps). Higher bandwidth allows for faster data transmission, enabling more efficient communication and data transfer between devices.

Cloud computing allows data to be stored on remote servers accessed via the internet, rather than being confined to physical servers located in an office. This flexibility enables users to access and manage their data from anywhere, promoting scalability and reducing the need for on-premises infrastructure.

A database is an organized system that stores related data electronically, allowing for efficient management and retrieval. It enables users to easily access, update, and manipulate data, facilitating tasks such as data analysis and reporting. This structure is essential for applications ranging from small personal projects to large enterprise systems.

Encryption refers to the method of transforming readable data into a coded format to protect it from unauthorized access. This process ensures that only individuals with the appropriate decryption key can access the original information, enhancing data security and privacy.

Latency refers to the time it takes for data to travel from the source to the destination in a network. It is a critical factor in network performance, as higher latency can lead to slower communication and reduced responsiveness in applications, impacting user experience and overall system efficiency.

A daemon is a background process that operates without direct user interaction. It performs automated tasks, such as handling requests, managing system resources, or running scheduled jobs. Daemons are essential for maintaining system functionality and efficiency, allowing users to focus on other tasks while the daemon manages routine operations.

Machine learning is indeed a subset of artificial intelligence (AI) that emphasizes the development of algorithms and statistical models allowing computers to improve their performance on tasks through experience and data. This learning process enables machines to identify patterns and make predictions without being explicitly programmed for specific outcomes.

In computing, a cache is a high-speed storage mechanism that temporarily holds frequently accessed data to improve retrieval times. By keeping this data close to the processor, caches reduce the time it takes to access information, enhancing overall system performance and efficiency.

A public cloud is a cloud computing model where resources and infrastructure, such as servers and storage, are shared across multiple organizations. This allows users to access scalable resources over the internet, promoting cost efficiency and flexibility, as they only pay for what they use without the need for significant capital investment in hardware.

Open-source software refers to programs that are made available to the public with their source code accessible for modification and redistribution. This allows users to customize the software to meet their needs, collaborate with others, and contribute to its improvement, fostering innovation and community-driven development.
