The correct option is (3)

Written once. read many times

Key Points

• WORM (Write Once, Read Multiple) discs include Compact Disc Recordable (CD-R) discs.
• These CDs can only store data once before it permanently resides there. A second recording onto the disc is not possible. Then, it can be read like a typical CD-ROM.
• Data or music is typically stored on a CD-R (Compact Disc-Recordable). Storage Size: At the moment, the industry norms for CDs are 74 minutes/650 MB, 80 minutes/700 MB (12 cm), and 21 minutes/185 MB (8 cm).

Additional Information

•  A CD or DVD A read-only disc is a read-only memory (CD-ROM). Commercially produced discs of this type cannot be used to store data once they have been generated.
• CD-R and CD-RW are the two different types of writeable CDs. With CD-R discs, you can only write to them once, but you can read from them repeatedly.
• You can write to CD-RW discs numerous times and read content from them an infinite number of times.

The correct answer is Interpreter.

Important Points

• A computer program that translates one program's instructions at a time into machine language is called an Interpreter.
• An interpreter translates one instruction at a time and executes that instruction immediately.
• Examples of interpreted languages are JavaScript, Python, Perl, etc.
• A compiler is a program that translates computer code written in one high programming language into machine-language or code that can be understood by a digital computer's CPU.
• An interpreter translates just one statement at a time from a program code into machine code, while a compiler scans the complete program and translates it into machine code at once.

Additional Information

• A Central processing unit (CPU) is considered as the brain of the computer, all types of data processing operations are performed by the CPU.
• It is generally composed of a control unit, main memory, and an arithmetic-logic unit.
• The process of mathematical modeling, performed on a computer, to represent the dynamic responses of one system by the behavior of another system modeled after it is known as the computer simulation.

The correct option is (2)

Non-Impact Printer

Key Points

• Characters and images are created using non-impact printers without any actual physical contact between the printing machine and the paper.
• It is a kind of printer that prints without striking or impacting a ribbon. They made use of inkjet, laser, xerographic, electrostatic, and chemical technologies. In general, non-impact printers are substantially quieter.
• Non-Impact printers like laser printers print text or graphics without actually touching the paper.

Additional Information

• An ink ribbon and paper come into touch directly when an impact printer is operating. The ink ribbon is struck by a metal or plastic head, which causes the ribbon to push against the paper and print the appropriate character (letter, digit, dot, or line) on the page.
• A printer that only prints individual characters. Dot matrix printers are the most common type of character printer.
• With speeds ranging from 150 to 2500 lines per minute, line printers print an entire line at once.
• High-speed printing applications use line matrix printers. Invoices, bank statements, product shipment and transportation documentation, product compliance labels, and more are all created using them. Text, bar codes, and graphics can all be printed on line matrix printers.
