What is a central processing unit (CPU)?

A CPU is the primary component of a computer responsible for executing instructions and performing calculations.

What is random access memory (RAM)?

RAM is a type of computer memory that stores data and instructions used by the central processing unit (CPU). RAM allows for fast access and retrieval of information, making it crucial for efficient computing.

What does graphics processing unit (GPU) mean?

GPU is a specialized electronic circuit primarily designed to accelerate the creation and rendering of images, videos, and animations. GPUs are commonly used in gaming, video editing, and other graphics-intensive applications.

What is solid state drive (SSD)?

SSD is a type of storage device that uses integrated circuit assemblies to store data persistently. Unlike traditional hard disk drives (HDDs), SSDs have no moving mechanical parts, which results in faster data access and improved reliability.

What does basic input/output system (BIOS) mean?

BIOS is a firmware that initializes hardware components and loads the operating system when a computer starts up. The BIOS also provides a low-level interface for configuring hardware settings.

What is hypertext markup language (HTML)?

HTML is the standard language used for creating web pages and applications. HTML uses tags to structure content and define its presentation on the internet.

What does uniform resource locator (URL) mean?

URL is the address used to access a resource on the internet, such as a webpage or a file. A URL typically consists of a protocol (e.g., http:// or https://), a domain name, and a path to the specific resource.

What is file transfer protocol (FTP)?

FTP is a standard network protocol used for transferring files between a client and a server on a computer network. FTP is often used for website maintenance, file sharing, and software updates.

What does hypertext transfer protocol (HTTP) mean?

HTTP is the protocol used for transmitting data over the internet. HTTP defines how requests and responses between a client (such as a web browser) and a server should be formatted and handled.

What is transmission control protocol/internet protocol (TCP/IP)?

TCP/IP is a set of networking protocols that enable the internet and many other computer networks to function. TCP ensures reliable transmission of data, while IP handles the addressing and routing of packets across networks.

What does virtual private network (VPN) mean?

VPN is a secure connection that encrypts and routes network traffic between a user's device and a private network over the internet. VPNs are commonly used to enhance privacy and security when accessing the internet remotely.

What is a domain name system (DNS)?

DNS is a hierarchical naming system that translates human-readable domain names (e.g., example.com) into internet protocol (IP) addresses. DNS plays a crucial role in allowing users to access websites by typing in familiar domain names instead of numeric IP addresses.

What does universal serial bus (USB) mean?

USB is a widely adopted interface used for connecting various devices to a computer. USB ports allow you to connect devices like keyboards, mice, printers, external hard drives, and more.

What is artificial intelligence (AI)?

AI refers to the simulation of human intelligence in machines, enabling them to learn, reason, and perform tasks that typically require human intelligence. AI powers technologies like voice assistants, recommendation systems, and autonomous vehicles.

What does internet of things (IoT) mean?

IoT describes the network of physical devices, vehicles, appliances, and other objects embedded with sensors, software, and connectivity, enabling them to collect and exchange data. IoT allows for smart and interconnected systems in various domains, including home automation, healthcare, and more.

What is hypertext transfer protocol secure (HTTPS)?

HTTPS is an extension of HTTP that adds encryption and security features. HTTPS ensures that data transmitted between a web browser and a website is encrypted, protecting it from unauthorized access or tampering.

What does javascript object notation (JSON) mean?

JSON is a lightweight data interchange format that is easy for humans to read and write and for machines to parse and generate. JSON is widely used for transmitting structured data between a server and a web application.

What is structured query language (SQL)?

SQL is a programming language used for managing and manipulating relational databases. SQL allows you to perform operations like querying data, inserting or updating records, and creating or modifying database structures.

What does wireless local area network (WLAN) mean?

WLAN refers to a wireless network that allows devices to connect and communicate within a limited area, such as a home, office, or campus. WLANs often use WiFi technology to provide wireless connectivity.

What is American Standard Code for Information Interchange (ASCII)?

ASCII is a character encoding standard that represents text in computers and communication devices. ASCII assigns unique numerical codes to different characters, such as letters, digits, and special symbols, allowing them to be stored and exchanged electronically.

What does simple service discovery protocol (SSDP) mean?

SSDP is a network protocol used to discover and announce network services and devices on a local area network (LAN). SSDP is commonly used in devices that support the universal plug and play (UPnP) framework.

What are domain name system security extensions (DNSSEC)?

DNSSEC is a set of extensions to the DNS protocol that provides cryptographic security measures to protect against DNS spoofing and tampering. DNSSEC ensures the authenticity and integrity of DNS records, enhancing overall DNS security.

What does WiFi protected access II (WPA2) mean?

WPA2 is a security protocol used to secure wireless computer networks. WPA2 provides stronger encryption and security features compared to its predecessor, WiFi protected access (WPA), making it a widely adopted standard for securing WiFi networks.

What is redundant array of independent disks (RAID)?

RAID is a technology that combines multiple physical disk drives into a single logical unit for improved performance, fault tolerance, or both. RAID is commonly used in servers and storage systems to provide data redundancy and increased data transfer speeds.

What does virtual private network (VPN) tunneling mean?

VPN tunneling refers to the process of encapsulating and encrypting network traffic within a VPN connection. When you establish a VPN tunnel, your data is securely transmitted between your device and the VPN server, protecting it from potential eavesdropping or interception.

What is basic input/output system (BIOS) flashing?

BIOS flashing, also known as firmware flashing, is the process of updating or replacing the firmware (BIOS) of a computer's motherboard. This is typically done to provide bug fixes, security updates, or additional features to the system. It involves installing the updated firmware onto the motherboard's firmware chip.
