GPU
A GPU, or Graphics Processing Unit, is a specialized processor designed to handle the complex calculations required by graphics-intensive applications. It is responsible for rendering images, videos, and animations.
DNS
DNS, or Domain Name System, is a system that translates domain names into IP addresses. It is responsible for mapping human-readable domain names to the IP addresses that computers use to communicate with each other.
VPN
A VPN, or Virtual Private Network, is a secure connection between two or more computers that allows them to communicate over the internet as if they were on the same local network. It is often used to protect sensitive data and maintain privacy.
URL
A URL, or Uniform Resource Locator, is an address that identifies a particular resource on the internet, such as a webpage or a file. It typically begins with “http” or “https” and contains the domain name, path, and other parameters required to access the resource.
HTML
HTML, or Hypertext Markup Language, is a language used to create webpages. It uses tags to define the structure and content of a webpage, including headings, paragraphs, images, and links.
CSS
CSS, or Cascading Style Sheets, is a language used to describe the appearance of a webpage, including colors, fonts, and layout. It works in conjunction with HTML to create visually appealing webpages.
PHP
PHP, or Hypertext Preprocessor, is a server-side scripting language used to create dynamic webpages. It is often used in conjunction with databases to create websites that can interact with users and store information.
SQL
SQL, or Structured Query Language, is a language used to manage and manipulate data stored in databases. It is used to create, update, and retrieve data from databases, and is commonly used in web development and data analysis.
API
API, or Application Programming Interface, is a set of rules and protocols used to communicate between different software applications. It allows applications to share data and functionality, making it easier to integrate them with other systems.
TCP
TCP, or Transmission Control Protocol, is a protocol used to establish reliable connections between computers for transmitting data over the internet. It is responsible for ensuring that data is transmitted accurately and reliably.
HTTP
HTTP, or Hypertext Transfer Protocol, is a protocol used to transfer data between a web server and a web browser. It is the foundation of the World Wide Web, and is responsible for sending HTML and other resources from web servers to web browsers.
FTP
FTP, or File Transfer Protocol, is a protocol used to transfer files between computers over the internet. It is commonly used for uploading files to web servers and downloading files from remote locations.
VPN
A VPN, or Virtual Private Network, is a secure connection between two or more computers that allows them to communicate over the internet as if they were on the same local network. It is often used to protect sensitive data and maintain privacy.
LAN
A LAN, or Local Area Network, is a network that connects computers within a small geographic area, such as an office or building. It is often used to share resources and data between computers within an organization.
WAN
A WAN, or Wide Area Network, is a network that connects computers over a large geographic area, such as a city, country, or even worldwide. It is often used to connect multiple LANs and enable communication between them.
DNS
DNS, or Domain Name System, is a system that translates domain names into IP addresses. It is responsible for mapping human-readable domain names to the IP addresses that computers use to communicate with each other.
DHCP
DHCP, or Dynamic Host Configuration Protocol, is a protocol used to automatically assign IP addresses to computers on a network. It ensures that each computer has a unique IP address and can communicate with other computers on the network.
RAID
RAID, or Redundant Array of Independent Disks, is a technology used to improve the performance and reliability of computer storage. It involves combining multiple hard drives into a single logical unit, providing redundancy in case of hardware failure.
BIOS
BIOS, or Basic Input/Output System, is a firmware that initializes the hardware of a computer when it is turned on. It is responsible for starting the operating system and providing a basic set of configuration options.
OS
OS, or Operating System, is the software that manages the hardware and software resources of a computer. It provides a user interface, manages processes and services, and controls the input and output of data.
GUI
GUI, or Graphical User Interface, is a type of user interface that uses visual elements such as icons and windows to interact with users. It is the primary interface used in modern operating systems and applications.
LAN
A LAN, or Local Area Network, is a network that connects computers within a small geographic area, such as an office or building. It is often used to share resources and data between computers within an organization.
WAN
A WAN, or Wide Area Network, is a network that connects computers over a large geographic area, such as a city, country, or even worldwide. It is often used to connect multiple LANs and enable communication between them.
NAT
NAT, or Network Address Translation, is a protocol used to map IP addresses between different networks. It is often used to enable multiple computers to share a single internet connection.
SMTP
SMTP, or Simple Mail Transfer Protocol, is a protocol used to send and receive email over the internet. It allows email to be sent from one computer to another, regardless of the email client or service used.
POP
POP, or Post Office Protocol, is a protocol used to retrieve email from a remote server. It is often used by email clients to download email from a server and store it locally on a computer.
IMAP
IMAP, or Internet Message Access Protocol, is a protocol used to retrieve email from a remote server. It is similar to POP, but provides more advanced features such as synchronizing messages between multiple devices and managing folders and labels.
SSH
SSH, or Secure Shell, is a protocol used to secure remote access to a computer or server. It encrypts data during transmission, preventing eavesdropping and unauthorized access.
SSL/TLS
SSL/TLS, or Secure Sockets Layer/Transport Layer Security, is a protocol used to secure communication over the internet. It encrypts data during transmission, preventing eavesdropping and unauthorized access.
VPN
A VPN, or Virtual Private Network, is a secure connection between two or more computers that allows them to communicate over the internet as if they were on the same local network. It is often used to protect sensitive data and maintain privacy.
XSS
XSS, or Cross-Site Scripting, is a vulnerability in web applications that allows attackers to inject malicious code into a webpage. It can be used to steal sensitive information or take control of a user’s computer.
CSRF
CSRF, or Cross-Site Request Forgery, is a vulnerability in web applications that allows attackers to execute unauthorized actions on behalf of a user. It can be used to perform actions such as transferring funds or changing settings without the user’s knowledge.
