Hardware Question 2:
________ is the other name for concentric circles on the platter of hard disk.
Answer (Detailed Solution Below)
Hardware Question 2 Detailed Solution
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.

Answer (Detailed Solution Below)
Hardware Question 3 Detailed Solution
Hardware Question 4:
Print resolution is measured as a number of _______.
Answer (Detailed Solution Below)
Hardware Question 4 Detailed Solution
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.

Hardware Question 8 Detailed Solution
Download Solution PDFThe 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.
System software acts as a bridge between the hardware and _____ software?
Answer (Detailed Solution Below)
Hardware Question 9 Detailed Solution
Download Solution PDFThe 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.
