• Java is a high-level object-oriented programming language.
• Java was developed by James Gosling.
• James Gosling is known as far of Java.
• Java was formerly known as Oak.
• Since Oak was already a registered company name later changed to Java.
• Java was originally developed at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform.

The correct answer is i - True, ii - False, iii - True

Key Points

• Statement i: This is true. High-level programming languages are more abstract and easier for humans to read and write.
• Statement ii: This is false. Debugging is process of finding and fixing errors or bugs in code, not writing code.
• Statement iii: This is true. Python supports multiple programming paradigms, including procedural, object-oriented, and functional programming.

So, statements are: i - True ii - False iii - True

The correct answer is Scrolling

Key Points

• The wheel located between two buttons on a mouse is primarily for scrolling.
• This means rotating wheel allows you to move up and down through content on a webpage, document, or application window, without having to click and drag a scroll bar.
• It's much faster and more convenient for navigating large amounts of information.

The correct answer is Impact printer.

Key Points

• Dot-matrix printer is a type of computer printing in which ink is applied to a surface and a low-resolution dot matrix is used for layout.
• It is also called an Impact printer.
• Dot-matrix printers employ a print head that goes back and forth or up and down on page and prints by impact, striking an ink-soaked cloth ribbon on paper, similar to a typewriter or line printer's print mechanism.
• Not only can a dot matrix printer create any patterns, but it can also print specified characters.
• Impact printer printers are noisy yet popular.
• There is no direct contact between ink ribbon and paper with non-impact printers.

The correct answer is i - True, ii - False, iii - True

Key Points

• Statement i: This is true. An algorithm is a step-by-step procedure for solving a problem.
• Statement ii: This is false. Assembly language is generally considered harder to understand and write than high-level languages because it is closer to machine code and less abstracted.
• Statement iii: This is true. SQL is used for managing and manipulating relational databases.

So, statements are: i - True ii - False iii - True

The correct answer is Secondary Storage.

• Auxiliary memory is popularly known as Secondary Storage.

Key Points

• Auxillary memory:
  • These units are among computer peripheral equipment.
  • Many times y are also referred to as secondary storage.
  • They have slower access rates for greater storage capacity and data stability.
  • This memory holds programs and data for future use and it is nonvolatile.
  • It is used to store inactive programs and to archive data.

Additional Information

• Primary storages are  key component of a computer system that enables it to function. Its examples are random access memory (RAM), read-only memory (ROM) and cache.
  • The RAM is a read/write memory.
    • The CPU can change contents of RAM at any time.
    • RAM is volatile.
  • Read-Only Memory (ROM) is non-volatile and retains its information even after power is turned off.

The correct answer is Magnetic Ink Character Recognition(MICR).

Key Points

• Magnetic ink character recognition is abbreviated as MICR.
• Magnetic ink character recognition (MICR) is a check identification and processing method.
• The MICR on a check is  string of characters at bottom left corner of check.
• The bank routing number, account number, and check number are among three groupings of numbers.
• MICR numbers are intended to be read by both humans and sorting machines.
• Due to usage of magnetic ink and unique fonts, y can't be faked or replicated.
• Enhanced protection against fraud and mechanisation of check processing are two of technology's advantages.
• MICR was created in late 1950s and is currently used all over world.

Additional Information

• Barcode Reader:
  • A Barcode reader or scanner is an electronic input device that can scan and decode barcodes.
  • These devices use optical technology such as infrared light.
• Optical Mark Reader: 
  • It can be considered as a Scanning device.
  • Optical mark recognition is process of capturing human-marked data from document forms such as surveys and tests.
  • They are used to read questionnaires, multiple-choice examination papers in form of shaded areas.
• Optical Character Reader:
  • It allows digitization of a flat, paper image and transfers it to computer where image can be manipulated.
  • It converts handwritten or printed text into machine-encoded text electronically or mechanically.

The correct answer is program.

Key Points

• a program is a specific set of ordered operations for a computer to perform. In modern computer that John von Neumann outlined in 1945,
• program contains a one-at-a-time sequence of instructions that computer follows. Typically, program is put into a storage area accessible to computer.
• A computer program in its human-readable form is called source code. Source code needs anor computer program to execute because computers can only execute ir native machine instructions.
• Therefore, source code may be translated to machine instructions using language's compiler. (Machine language programs are translated using an assembler) The resulting file is called an executable. 

Additional Information

• Input device: An input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. 
• Hardware: Computer hardware includes physical parts of a computer, such as  case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and morboard.
• Chip set: The chipset is basically electronics on morboard that communicate with all connected components.

The correct answer is Application

Key Points

• An application, or application program, is a software program that runs on your computer. Web browsers, e-mail programs, word processors, games, and utilities are all applications. The word "application" is used because each program has a specific application for user.
• In contrast, system software consists of programs that run in background, enabling applications to run. These programs include assemblers, compilers, file management tools, and operating system itself. Applications are said to run on top of system software since system software is made of "low-level" programs. While system software is automatically installed with operating system, you can choose which applications you want to install and run on your computer.
• Macintosh programs are typically called applications, while Windows programs are often referred to as executable files. This is why Mac programs use .APP file extension, while Windows programs use .EXE extension. Though y have different file extensions, Macintosh and Windows programs serve same purpose and can both be called applications.

The correct answer is Control panel.

Key Points

• Control panel:
  • It is used to change system settings on a computer.
  • With help of this, we can change hardware and software properties of a computer.
  • It is an important part of a computer.
  • It is used to control all systems.

Additional Information

• Linker:
  • It is used to create connections between all functions of a program to continue program execution.
  • It is a part of operating system.
  • It is a utility software.
• Debugger:
  • To do debugging tools are used which are called Debugger.
  • It is a part of debugging tool.
  • With its help, we can correct errors in computer programs.
• Compiler:
  • It is used to convert high-level languages into low-level languages on a computer.
  • It translates whole program at a time on computer.
