The correct answer is program that accepts a program written in a high level language and produces an object program.

Key Points

• A compiler is a specialized software tool that translates programs written in high-level programming languages (like C, C++, Java, etc.) into machine language or an intermediate code.
• This machine language is a set of instructions that a computer's central processing unit (CPU) can directly execute.
• The resulting output is often called an object program or binary, which can be run on a computer without need for source code.
• This process involves several stages, including lexical analysis, syntax analysis, semantic analysis, optimization, and code generation.

In computing, a device driver (commonly referred to simply as a driver) is a computer program that operates or controls a particular type of device that is attached to a computer. A driver provides a software interface to hardware devices, enabling operating systems and or computer programs to access hardware functions without needing to know precise details of hardware being used.

The correct answer is Port.

Key Points

• PORT:
  • A 'Port' in computer terminology, is  communication endpoint using which an external device can be connected to computer.
  • The morboard contains slots called 'ports' into which a cable of an external device is plugged.
  • The identification of a port for a particular transport protocol and address is done through a 16-bit unsigned number called 'port number'.
  • Some important types of Port - Serial Port, Parallel Port, PS/2 Port, Universal Serial Bus (or USB) Port, VGA Port, Modem Port, Power Connector, Firewire Port, Ernet Port, Game Port, and Digital Video Interface (DVI) port.

Additional Information

• RING:
  • In 'Ring' topology of computer networking, all terminals are linked to each or in form of a ring and data circulate from one terminal to anor until it reaches destination point.
  • This type of networking does not require a network server to control connectivity between workstations.
• ?BUS:
  • ?In this type of computer networking, terminals are connected to a single central cable also called 'backbone'.
  • Here, in case of 'bus' topology, only one terminal can transmit a signal at a time and signal travels in both directions to all terminals till it finds destination point.
  • Since only a single cable is used in this type of networking, it is less expensive than ors.
• ?ZIP:
  • ?'Zip' file in computer terminology refers to a collection of different files compiled into a single compressed file of smaller size.
  • This zipping of files saves disk space as zipped archive takes up less space in comparison to its uncompressed version.

The correct answer is Access.

• In DASD,  full form of ‘A’ is Access.

Key Points

• Direct access storage device is a general term for magnetic disk storage devices.
• It has been used in mainframe and minicomputer environments and is sometimes used to refer to hard disk drives for personal computers. 
• A redundant array of independent disks (RAID) is also a type of DASD.
• The term "direct access" means all data can be accessed directly in same amount of time rar than having to progress sequentially through data.

The correct answer is option 1) i.e. Cache.

Key Points

•  The basic purpose of cache memory is to store program instructions that are frequently re-referenced by software during operation.
• Fast access to se instructions increases overall speed of software program.
• Cache memory is not associated with ROM, rar it is called as CPU or Random access memory which a computer microprocessor can access more quickly than a regular RAM.
• This memory is typically integrated directly with CPU chip or placed on a separate chip that has a separate bus interconnect with CPU.

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

Key Points

• Statement i: This is true. C++ is indeed an object-oriented programming language.
• Statement ii: This is true. A compiler translates high-level code into machine code all at once before execution.
• Statement iii: This is true. Machine language consists of binary code directly executed by CPU.

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

The correct answer is Spider.

Key PointsSpider

• A spider is a software program that travels web, locating and indexing websites for search engines.
• All major search engines, such as Google and Yahoo!, use spiders to build and update ir indexes.
• These programs constantly browse Web, traveling from one hyperlink to anor.

Additional InformationBug

• A software bug is an error, flaw, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.
• Bugs can trigger errors that may have ripple effects.
• Bugs may have subtle effects or cause program to crash or freeze computer.

The correct answer is .tmp.

Key Points

• Temporary files are files used by  system to store data while running programs or creating permanent files, such as Word documents or Excel spreadsheets.
  • .tmp is an extension of a temporary file.
  • It is created to hold information while a file's being created or modified.
  • The temporary file will be deleted after program is closed.
  • The storage location of a temporary file varies depending on program and operating system.
  • If temporary file is needed again after it's deleted, it is recreated when program is opened again.

Additional Information

• .txt is an extension of a text file.
• .tnt file extension is associated with online 3D designing tool for Microsoft Windows operating system called TurnTool, developed by Turntool ApS.
• .tar file extension is a file in Consolidated Unix Archive format.

The correct answer is a Graphics tablet.

Important Points

• A graphics tablet consists of an electronic writing area and a special ‘pen’ that works with it.
• A graphics tablet is a device that allows us to hand draw animations, images, and graphics. It is a computer input device.
• The special pen used in a graphics tablet is known as a stylus. The tablet is also used to capture handwritten signatures.
• In year 1888 Elisha Gray patented  first electronic handwriting device  Telautograph.

Additional Information

• A trackball is a pointing device used to track a pointer on a computer system. It consists of a ball held by a socket containing sensors.
• A plotter is a printer like a computer hardware device used for printing vector graphics.

The correct answer is option - 1.

Key Points

• A pointing device that detects two-dimensional motion relative to a surface, allowing users to interact with graphical interface of a computer.

• A device comprising keys that allow users to input text, numbers, and execute commands into a computer.

• A device that converts documents and images into digital data by scanning m, allowing digital information to be stored, viewed, or processed on a computer.

• An input device consisting of a stick that pivots on a base and reports its direction to device it is controlling, often used for gaming.

• A computer input device in form of a light-sensitive wand used in conjunction with a computer's CRT display, allowing user to point to displayed objects or draw on screen.

Additional Information

• Printers are output devices, not input devices. They produce a hard copy of documents, images, or graphics stored on a computer.
• Monitors are output devices that display images generated by computers. They do not send data into computer.
