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 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.

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.

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.
