Drum Printer, Laser Printer

Concept:-

A page printer is a non-impact printer that prints a full page at once, whereas a line printer publishes a complete line of text at a time.

Key Points

• A drum printer is the type of line printer, and a laser printer is also called a page printer.
• Before moving on to the next line of text, the line printer outputs the previous line. The printing mechanism of early line printers consisted of a series of slugs connected in a chain.
• A printer with raised characters on a rotating drum that the paper is pressed against.
• The print drum is quieter than a chain because it rotates silently, as opposed to the clatter that a chain creates. It prints only the characters on the drum, just like a chain printer.
• Popular computer printers like laser printers use non-impact photocopier technology, which avoids damaging the paper with keys.
• Ribbon printer (belt printer) impact line printing technique where the font's characters and timing marks are etched onto a steel band.

The correct answer is CMOS.

Key Points

• CMOS (Complementary Metal-Oxide-Semiconductor) is a technology for constructing integrated circuits. It is also a term used to refer to the chip that stores the BIOS settings in a computer.
• The BIOS (Basic Input/Output System) is firmware used to perform hardware initialization during the booting process and to provide runtime services for operating systems and programs.
• While the BIOS itself is stored in ROM (Read-Only Memory), the settings and configurations that the BIOS uses are stored in the CMOS chip, which requires power to maintain the information.
• In summary, the CMOS chip stores the BIOS settings, making it crucial for the proper booting and configuration of the computer system.

Additional Information

• Option 2: CPU - This is incorrect because the CPU (Central Processing Unit) is the main processing unit of the computer and does not store the BIOS.
• Option 3: HDD - This is incorrect because the HDD (Hard Disk Drive) is used for data storage and does not store the BIOS.
• Option 4: RAM - This is incorrect because RAM (Random Access Memory) is volatile memory used for temporary storage of data and does not store the BIOS.

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.
