The correct answer is Liquid Crystal Display

Key Points

The technology powering display on your phone or even your TV is a lot different than it was even ten years ago. From phones to TVs, screens used could be eir a display based on OLED (Organic Light-Emitting Diode) technology or LCD (Liquid Crystal Display) technology.

Liquid Crystal Display:

• LCD stands for “Liquid Crystal Display”.
• It is a combination of two states of matter,  solid and liquid. LCD uses a liquid crystal to produce a visible image.
• LCD’s technologies allow displays to be much thinner when compared to a cathode ray tube (CRT) technology.
• It is composed of several layers which include two polarized panel filters and electrodes.
• These screens work on principle of blocking light rar than emitting light. LCD’s requires backlight as y do not emit light by m.
• Most of electronic devices mainly depend on liquid crystal display technology for ir display.

Hence, it can be concluded from given points that acronym LCD stands for Liquid Crystal Display.

The correct answer is Control panel.

  • 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.

The correct answer is Graphics software.

Key Points

• Application software
  • It is a program or a group of programs designed for end-users.
  • It is a term that is used for software created for a specific purpose. 
  • In short, it is called an App.
• Graphics software
  • It is visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone, to inform, illustrate, or entertain.
  • Graphic art software is a subclass of  application software used for graphic design, multimedia development, stylized image development, technical illustration, general image editing, or simply to access graphic files. Hence, Option 4 is correct.
  • Art software uses eir raster or vector graphic reading and editing methods to create, edit, and view art.
  • Most art software includes common functions, creation tools, editing tools, filters, and automated rendering modes.
  • Many, however, are designed to enhance a specialized skill or technique.
  • Specialized software packages may be discontinued for various reasons such as lack of appreciation for result, lack of expertise and training for product, or simply not worth time and money investment, but most likely due to obsolescence compared to newer methods or integration as a feature of newer more complete software packages.

Additional Information

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 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.

• 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 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 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.
