Google Chrome, called "Google Chrome", is a web browser developed by Google. The browser is based on other open source software, including WebKit, with the goal of improving stability, speed and security. flexibility and create a simple and efficient user interface.
The name of the software comes from the web browser GUI (Graphical User Interface) called Chrome. The beta test version of the software was released on September 2, 2008. It is available in 50 languages and is available for download in Microsoft Windows, macOS, Linux, Android, and iOS versions.
Google will launch “mini programs” enhanced web applications (Progressive Web Apps, referred to as PWA) on Chrome. In November 2018, Google announced that it would remove all ads on its Chrome 71 web browser from December 2018 on websites that continue to provide abusive usage experiences.
Google Chrome is characterized by simplicity and speed. Google Chrome supports multi-tab browsing. Each tab page runs in an independent "sandbox". While improving security, the crash of one tab page will not cause other tab pages to be closed. In addition, Google Chrome is based on the more powerful JavaScript V8 engine, which is not possible in current web browsers.
Advantages
Not easy to crash
The biggest highlight of Chrome is its multi-process architecture, protection The browser will not crash due to malicious web pages and applications. Each tab, window, and plug-in runs in its own environment, so problems with one site won't affect other sites. This architecture further improves the security of the system by confining each site and application to a closed environment.
Fast speed
Uses WebKit engine. WebKit is simple, compact, and uses memory efficiently, making it easy for new developers to get started. Chrome has a DNS pre-interception feature. When browsing the web, "Google Chrome" can query or pre-intercept the IP addresses of all links on the web page. Landing page. Chrome has GPU hardware acceleration: When GPU hardware acceleration is activated, using "Google Chrome" to browse websites that contain a large number of images can render faster and avoid image cracking when the page is scrolled.
In April 2013, Google announced that it would develop a new independent browser engine Blink for the Chrome browser. In the latest Chrome development version, Blink has officially appeared.
Nearly invisible
Saying that Chrome’s interface is simple is not enough to describe its simplicity. Chrome hardly looks like an application. Most of the screen space is used to display the sites the user visits, and Chrome buttons and logos are not displayed on the screen. Chrome's designers said they wanted users to forget they were using a browser, and their goal was largely achieved.
Easy Search
One of Chrome's signature features is the Omnibox, a universal toolbar located at the top of the browser. Users can enter the website address or search keywords in the Omnibox, or enter both at the same time, and Chrome will automatically perform the operations the user wants. Omnibox can understand user preferences. For example, if a user likes to use the search function of the PCWorld website, once the user visits the site, Chrome will remember that the PCWorld website has its own search box and allow the user to choose whether to use the search function of the site. If the user chooses to use the search function of the PCWorld website, the system will automatically perform the search operation.
Tab flexibility
Chrome provides new features for tabbed browsing. Users can "grab" a tab and drag it into a separate window. Users can combine multiple tabs in one window. Chrome can use the configuration of a certain tab that the user likes when it starts. Other browsers require third-party plug-ins to provide this feature.
More secure
Blacklists: "Google Chrome" regularly updates blacklists to prevent phishing and malware. and warn users when they attempt to browse websites that may cause computer damage. This service is also available through the use of another free application programming interface (API) "GoogleSafe Browsing API". While updating and maintaining these blacklists, Google will also notify the included websites to prevent website owners from not knowing that the websites contain malware.
Sandboxing: Each tab page in "Google Chrome" is a sandbox (sandbox) to prevent "malware from damaging the user's system" or "using the tab page to affect other Bookmark page". Adhering to the principle of least privilege, the permissions of each action will be limited. It can only perform calculations but cannot write files or read files from sensitive areas (such as My Documents, Desktop). The Sandbox Team is a team that says they "take existing restrictions on running programs and make those restrictions a prison." For example, malware running in one of the tabs will not be able to steal credit card numbers, interfere with The mouse works, or tells the system to run a program on startup, and the malware aborts as soon as the tab is closed.
Plugins: Plugins usually do not have a unified standard and cannot be sandboxed like tabs. These usually need to run at the browser's own security level or higher. To reduce the risk of attacks, plugins run independently. Starting from version 5.0, "Google Chrome" has built-in Adobe Flash Player to ensure that the latest version is used to reduce the risk of being attacked. Later, in version 9.0, the Flash player was built into a sandbox and ran independently. This technology is a milestone in the advancement of Chrome security. It's particularly important for Windows XP users because it's the only browser on the platform that offers Flash embedded sandboxing. Starting from version 8.0, "Google Chrome" has a built-in PDF reader that runs independently in a sandbox.
Multiprocessing: allows multiple programs to run at the same time without affecting each other, and each web page tag is independent Due to the existence of window programs, when resources are too high or crash, the entire program will not crash due to a pause.
Task Manager (Task Manager): A very unique tool. Users can check which websites occupy the most memory, download traffic and CPU resources, which is helpful for managing various tabs and Plug-ins also facilitate users to terminate malicious operations.
Fraud and malware protection: Google Chrome can send real-time warnings when it detects that a website you're browsing may be harmful. The browser sends part of the visited URL to Google to see if the URL is listed on a list of scams and malicious sites. (Phishing and malware detection capabilities).
Auto-updates (Auto-updates): To ensure that you are protected by the latest security updates, "Google Chrome" will regularly check for updates to ensure that the updates are always the latest version. Update checks ensure that the latest security features and fixes are being used. The browser automatically updates the new version without requiring any action from the user. After the update, it will be automatically used on the next startup.
Icon evolution
News on February 5, 2022, since the Google Chrome browser was first released in 2008 , the icon design of a blue circle surrounded by three pinwheel-shaped slices has remained the same, with only minor adjustments.
According to reports, the new icon removes shadows, optimizes proportions, and brightens colors, thereby simplifying the main brand icon to be in line with Google’s more modern brand expression.
