Web Utilities

Utilities are programs that make computing easier. Web utilities are specialized utility programs that make using the internet and the web easier and safer. Some of these utilities are Internet services for connecting and sharing resources over the Internet. Others are browser-related programs that either become part of your browser or are executed from your browser.


WEB-BASED APPLICATIONS :

Typically, application programs are owned by individuals or organizations and stored on their computer system's hard disk. An emerging trend, however, is to free users from owning and storing applications. The most widely used Web-based applications are free using Web-based services that provide access to programs that run within your browser window. For example, Google Apps provides free ac cess to programs with capabilities similar to Microsoft's Word, Excel, and Power Point. Another type of Web-based application typically runs on your desktop like a tra ditional application program. To use one of these, you connect to the Web site of an application service provider (aps), copy the application program to your com puter system's memory, and then run the application. Unlike Web-based services, access is typically not free and the appli cations are more specialized.


FTP :

File transfer protocol (FTP) and Secure FTP (SFTP) are Internet stan dards for transferring files. Using FTP software, you can copy files to your computer from specially configured FTP servers. This is called downloading. You also can use FTP to copy files from your computer to another computer on the Internet. This is called uploading.


PLUG-INS :

Plug-ins are programs that are automatically started and operate as a part of your browser. Many Web sites require you to have one or more plug-ins to fully experience their content. Some widely used plug-ins include.

• Acrobat Reader from Adobe-for viewing and printing a variety of standard forms and other documents saved in a special format called PDF. Windows Media Player from Microsoft-for playing audio files, video files, and much more.

•QuickTime from Apple-for playing audio and video files.

•Real Player from Real Networks for playing audio and video files.

•Shockwave from Adobe-for playing Web-based games and viewing concerts and dynamic animations.

Some of these utilities are included in many of today's browsers and operating systems. Others must be installed before they can be used by your browser.


FILTERS :

Filters block access to selected sites. The Internet is an interesting and multifaceted arena. But one of those facets is a dark and seamy one. Parents, in particular, are concerned about children roaming unrestricted across the Internet. Filter programs allow parents as well as organizations to block out selected sites and set time limits. Additionally, these programs can monitor use and generate reports detailing the total time spent on the In ternet and the time spent at individual Web sites, chat groups, and newsgroups.


INTERNET SECURITY SUITES :

An Internet security suite is a collection of utility programs designed to maintain your security and privacy while you are on the Web. These programs control spam, protect against computer viruses, provide filters, and much more. You could buy each program separately; however, the cost of the suite is typically much less. Two of the best-known Internet security suites are Quick Heal and Symantec's Norton Internet Security.

Automations and robotics

Automations and robotics refer to the use of technology to automate and perform tasks that were previously done by humans. Automation involves the use of software, machines, and other systems to perform tasks without human intervention. Robotics, on the other hand, involves the design and development of machines that can perform tasks autonomously or with limited human intervention. Automations and robotics are widely used in industries such as manufacturing, healthcare, transportation, and agriculture. In manufacturing, robots are used to perform repetitive and dangerous tasks, such as welding and painting. In healthcare, robots are used to perform surgeries and assist patients with mobility issues. In transportation, automated systems are used to control traffic flow and ensure the safety of drivers and passengers. In agriculture, robots are used to plant and harvest crops, reducing the need for manual labor. Advancements in technology have led to the development of more sophisticate...
