Terms definitions
1. Google ( Google ) Primarily acknowledged for its search engine, Google is a universally esteemed technology corporation. The company, established in 1998 by Sergey Brin and Larry Page, has expanded significantly, branching out into numerous tech-related fields. Google offers a wide array of services and products, encompassing Android, YouTube, Cloud, Maps, and Gmail. It also manufactures hardware like Chromebooks and Pixel smartphones. Since 2015, Google has been a subsidiary of Alphabet Inc. and is celebrated for its inventive spirit and workplace environment that promotes employees' personal projects. Despite confronting several ethical and legal challenges, Google continues to influence the tech sector with its groundbreaking innovations and technological progress, including the creation of Android OS and the purchase of companies specializing in AI.
2. email. Email, a vital communication tool since its introduction in 1975, has become an integral part of our daily lives. This system functions over computer networks and the internet, enabling global message transmission and reception. While 'email' is the commonly accepted term in style guides, variations such as 'E-mail' are occasionally used, especially in American and British English contexts. The process of this system includes a sender composing a message via a Mail User Agent (MUA), which then sends it to the recipient's mail exchange server. The recipient's MUA subsequently retrieves the message. Thanks to the Multipurpose Internet Mail Extension (MIME), emails can now include multimedia content. For safety, email systems employ a store-and-forward model, whereby email servers receive, forward, store, and deliver messages. This method facilitates email exchanges without requiring users to be online simultaneously.

At its launch in 2004, Gmail provided a storage capacity of one gigabyte per user, which was significantly higher than its competitors offered at the time. Today, the service comes with 15 gigabytes of storage for free for individual users, which is divided among other Google services, such as Google Drive, and Google Photos. Users in need of more storage can purchase Google One to increase this 15 GB limit. Users can receive emails up to 50 megabytes in size, including attachments, and can send emails up to 25 megabytes. Gmail supports integration with Google Drive, allowing for larger attachments. Gmail has a search-oriented interface and supports a "conversation view" similar to an Internet forum. The service is notable among website developers for its early adoption of Ajax.

Google's mail servers automatically scan emails for multiple purposes, including to filter spam and malware and, prior to June 2017, to add context-sensitive advertisements next to emails. This advertising practice has been significantly criticized by privacy advocates with concerns over unlimited data retention, ease of monitoring by third parties, users of other email providers not having agreed to the policy upon sending emails to Gmail addresses, and the potential for Google to change its policies to further decrease privacy by combining information with other Google data usage. The company has been the subject of lawsuits concerning the issues. Google has stated that email users must "necessarily expect" their emails to be subject to automated processing and claims that the service refrains from displaying ads next to potentially sensitive messages, such as those mentioning race, religion, sexual orientation, health, or financial statements. In June 2017, Google announced the end of the use of contextual Gmail content for advertising purposes, relying instead on data gathered from the use of its other services.
