The correct answer is the "Dot-matrix printer".

Key Points

• Plotter: The plotter is a kind of printer which is used for printing vector lines. It uses a simple pen and paper.
• Laser printer: The laser printer is an example of a non-impact printer. It uses laser technology to print the content. This kind of printer is used mostly in large companies.
• Inkjet printer: The inkjet printer is an example of a non-impact printer. This kind of printer is used mostly in homes, businesses and so on. It uses a different pattern of ink droplets to print the content.
• Dot-matrix printer: The dot-matrix printer is an example of an impact printer. It has 9-24 pins which are situated at the printer head. It is commonly used for printing in applications like payroll and accounting. 

The correct answer is the Dot-matrix printer.

Additional Information

• Printer is referred to as an output device. The printer is divided into two parts. These are impact printers and non-impact printers.
• Impact printers use a kind of pin and hammer system to print a document. It is less costly than the non-impact printer.
• Non-impact printers use ink in any form to print a document. It is the best for printing photographs.

The correct answer is Tracks.

• Tracks are the other name for concentric circles on the platter of the hard disk. A disk drive track is a circular path on the surface of a disk or diskette on which information is magnetically recorded and from which recorded information is read.
  • A track is a physical division of data in a disk drive, as used in the Cylinder-Head-Record (CHR) addressing mode of a CKD disk. The concept is concentric, through the physical platters, being a data circle per each cylinder of the whole disk drive.
  • In other words, the number of tracks on a single surface in the drive exactly equals the number of cylinders of the drive.
• A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.
  • The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces

The correct answer is Dots Per Inch (dpi).Key Points

• Print resolution is measured as the number of Dots Per Inch (dpi).
  • ​It can be said that Resolution (in terms of print)  is a measure of the number of dots that a device can put in one square inch of page space.
  • The higher the dot density, the higher the resolution of the print or scan.
  • A printer with 600 DPI is a printer that prints 600 x 600 per square inch or 360,000 dots per inch.
  • Increasing the DPI will make the size of the printed image smaller while decreasing the DPI will make the size of the printed image larger.

Additional Information

• Characters-per-second (cps) is a unit of measure used to describe the speed of dot-matrix and daisy-wheel printers.
• Lines-Per-Minute (LPM) is the number of lines of text a printer is capable of producing in one minute. It is affected by factors such as text size, resolution, and colour.
• Pages per minute (PPM) is a printer speed measurement standard. It is the measurement standard for how fast a printer can print a standardized page.

The correct answer is Barcode Reader.

Key Points

• Barcode Reader:
  • This is an example of an input device used to read information contained in barcodes.

Additional Information

• Speaker:
  • This is an example of an output device.
  • It produces sound through a vibrating transducer called a driver.
•  DLP Projector:
  • It stands for Digital Light Processing Projector.
  • This is an example of an output device.
• Bubblejet Printer:
  • A Bubblejet printer is an example of an output device that is used to print information on paper.

The correct answer is Toggle Keys

Key Points

Toggle key:

• A toggle key is a key that is used to turn a function on or off, or to switch between two functions.
• A toggle key can also be used as an accessibility option to alternate the input mode of keys.
• Examples of toggle keys are the caps lock key, number lock key and scroll lock key.

The correct answer is the Basic input/output system.

Important Points

• It is the program a personal computer's microprocessor uses to get the computer system started after you turn it on.

The correct answer is Port.

Key Points

• PORT:
  • A 'Port' in computer terminology, is the communication endpoint using which an external device can be connected to the computer.
  • The motherboard 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 the '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, Ethernet Port, Game Port, and Digital Video Interface (DVI) port.

Additional Information

• RING:
  • In 'Ring' topology of computer networking, all terminals are linked to each other in form of a ring and the data circulate from one terminal to another until it reaches the destination point.
  • This type of networking does not require a network server to control the connectivity between workstations.
• ​BUS:
  • ​In this type of computer networking, the terminals are connected to a single central cable also called 'backbone'.
  • Here, in the case of 'bus' topology, only one terminal can transmit a signal at a time and the signal travels in both directions to all the terminals till it finds the destination point.
  • Since only a single cable is used in this type of networking, it is less expensive than others.
• ​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 the zipped archive takes up less space in comparison to its uncompressed version.

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 the user.
• In contrast, system software consists of programs that run in the background, enabling applications to run. These programs include assemblers, compilers, file management tools, and the operating system itself. Applications are said to run on top of the system software since the system software is made of "low-level" programs. While system software is automatically installed with the 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 the .EXE extension. Though they have different file extensions, Macintosh and Windows programs serve the same purpose and can both be called applications.

The correct answer is Local Area Network (LAN):

Important Points

• It is a computer network within a small geographical area.
• A LAN is composed of interconnected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN.

Additional Information

• Photoshop is a powerful photo editing tool by Adobe.
• An Operating System (OS) is an interface between a computer user and computer hardware.
• An operating system is software that performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

The correct answer is Pen drive.

• Flash drive is popularly known as a pen drive.

Key Points
