The correct answer is Inkjet Printers

Key Points

• Inkjet Printers print characters on the paper by spraying ionized ink at a sheet of paper.
• These printers do not use a ribbon, unlike Dot-Matrix, Line, and Drum printers.
• The ink is directed onto the paper in the form of tiny droplets to create text and images.
• They are known for producing high-quality prints with good resolution and color.

Additional Information

• Dot-Matrix Printers use a print head that moves back-and-forth or in an up-and-down motion, striking an ink-soaked cloth ribbon against paper.
• Line Printers print an entire line at once and typically use a ribbon.
• Drum Printers have a rotating drum with raised characters and use a ribbon to transfer ink to the paper.
• Inkjet Printers are widely used in both home and office environments for their versatility and quality.

What is Database Software or DBMS?

• Database Management System (DBMS) is an application software for storing and retrieving users' data while considering appropriate security measures. It consists of a group of programs that manipulate the database. The DBMS accepts the request for data from an application and instructs the operating system to provide the specific data. In large systems, a DBMS helps users and other third-party software to store and retrieve data.

Utility software:

Hint Point:

• The system software is used to operate computer hardware
• It is an interface between Application Software and hardware of the computer.
• The System Software is designed to manage the system resources and it also provides a platform for Application Software to run.

Electronic mail, or email, is the transmission of text-based messages among networked computers. Email is one of the earliest and most basic messaging resources on the Internet and in many ways it still acts as the lowest common denominator for computer communications. Types of email services:

• Free Web-based Email Services: These are the commonly used email accounts accessible through a web browser (such as Internet Explorer, Firefox etc.). They generally use HTTP Protocol for accessing mail. Example: Yahoo Mail, Hotmail, Gmail (whose attachment size limit is 25 MB) offer free web-based email services. These services are run on financial profit from advertisements. Advertisers pay service providers to expose email account holders to advertisement.
• Priced Web-based Email Services: There are also priced web-based email service providers. Many of the free web-based email service providers such as Yahoo! And Hotmail do offer premium account on payment basis. Advantage of utilising such services include more secured transaction of communication; personalised email address; better spam filtration as well as increased storage space. Priced email services are most useful in business-related message exchanges.
• Private Email Services: Most of the institutions/organisations have their own dedicated mail server and offer mail account for free to their staff and other members of the institution. These accounts exist only till one is member of that institution. For example: abc@ugc.ac.in; abc@satyam.net etc.

Hence, we conclude that email attachment size limit in Gmail is 25 MB.
