Which of the following hardware devices would show the most detailed view of graphical content?

  1. 3D camera
  2. CCTV camera
  3. Very-high resolution display device
  4. Web camera used to record lectures
  5. Airplane's black box

Solution

The correct answer is (c) Very-high resolution display device.

A very-high resolution display device is designed to output and present graphical content with a high level of detail, allowing for a clearer and more intricate visual experience. "Very-high resolution display devices that will show content in incredible detail and dramatically improve the viewing experience (think clarity and resolution way beyond 1080p HD)"[1]The other options are primarily input or recording devices, or a data recorder, and are not designed for displaying content in detail:

  • (a) 3D camera: An input device that captures images in three dimensions.
  • (b) CCTV camera: An input device used for surveillance, capturing video footage.
  • (d) Web camera used to record lectures: An input device for capturing video and audio.
  • (e) Airplane's black box: A flight recorder that stores flight data and cockpit voice recordings, not a display device.

Which of the following statements is/are CORRECT regarding computer software?

  1. Application software and program software are the two main types of computer software.
  2. A custom application software is developed with the intention of selling the software in multiple copies.
  3. Microsoft office is an example of application software.
  4. Microsoft Windows is the default software installed by computer manufacturers.
  5. To install a software, download the software that works with the operating system installed in the computer
(c) Microsoft office is an example of application software. (e) To install a software, download the software that works with the operating system installed in the computer.

Explanation:

  • Statement (a) is incorrect:The two main types of computer software are application software[2] and system software[3], not "program software." System software includes operating systems, device drivers, and utilities, while application software includes programs like word processors, web browsers, and games.

    Software Type Personal Workgroup Enterprise
    System Software Smartphone, Tablet, Personal Computer and Workstation operating systems Network Operating Systems Server and mainframe Operating Systems
    Application Software Word-proccessing, spreadsheet, database and graphics programs Email, group-scheduling, shared-work and colloboration applications General-ledger, order-entry, payroll and human resources applications

  • Statement (b) is incorrect:Custom application software is typically developed for a specific user or organization to meet their unique requirements and is not intended for mass sale in multiple copies. Software intended for mass sale is usually referred to as off-the-shelf or commercial software.
  • Statement (c) is correct:Microsoft Office, which includes programs like Word, Excel, and PowerPoint, is a suite of application software designed to perform specific tasks for users.
  • Statement (d) is incorrect:While Microsoft Windows is a very common operating system pre-installed by many computer manufacturers, it is not the only default software. Other operating systems like macOS and various Linux distributions are also pre-installed by different manufacturers.
  • Statement (e) is correct:Software must be compatible with the operating system installed on the computer to function correctly. Downloading and installing software designed for a different operating system will likely result in installation errors or the software not running.

Which of the following is/are NOT (a) system software?

  1. Disk Defragmenter
  2. Google's Android
  3. Ubuntu
  4. Microsoft Edge
  5. Printer Driver

Solution

The correct answer is (d) Microsoft Edge.

Microsoft Edge is a web browser, which falls under the category of application software. Application software is designed to perform specific tasks for the user, such as browsing the internet, word processing, or playing games.

The other options are all examples of system software:

  • (a) Disk Defragmenter:A utility program that optimizes disk performance by reorganizing fragmented files.
  • (b) Google's Android: An operating system, which is a core component of system software that manages computer hardware and software resources.
  • (c) Ubuntu:Another operating system, similar to Android in its function as system software.
  • (e) Printer Driver: A type of device driver, which is system software that allows the operating system to communicate with hardware devices like printers.

Which of the following is INCORRECT regarding software?

  1. Software is essential to work with any computer.
  2. Google’s Android and Apple’s iOS are examples of application software.
  3. There are two major types of software: system software and application software.
  4. System software is required to control access to system resources and manage memory and files.
  5. Virtual machine is a software that can enable running multiple operating systems on a computer.

(b) Google's Android and Apple's iOS are examples of application software.

Explanation

  • Software is essential to work with any computer. This statement is correct. Without software, a computer is essentially a collection of hardware components that cannot perform any useful tasks.
  • Google's Android and Apple's iOS are examples of application software. This statement is incorrect. Android and iOS are examples of operating systems, which fall under the category of system software, not application software. Application software refers to programs designed for specific tasks, like word processors or web browsers.
  • There are two major types of software: system software and application software. This statement is correct. System software manages the computer's resources, while application software helps users perform specific tasks.
  • System software is required to control access to system resources and manage memory and files.This statement is correct. Operating systems, a type of system software, perform these crucial functions.
  • Virtual machine is a software that can enable running multiple operating systems on a computer.This statement is correct. Virtual machine software creates a virtualized environment where multiple operating systems can run concurrently on a single physical machine.

Which of the following is NOT a unit of measurement for data?

  1. Kilobyte
  2. Terabyte
  3. Youbyte
  4. Megabyte
  5. Zettabyte

The correct answer is (c) Youbyte.

TABLE 1.5 Units of measure for data[4]

Unit of Messure Size Equivalent to
Byte 1 byte One alphanumeric character
Kilobyte 1024 bytes The text of a joke or very short story
Megabyte 1024 Kilobytes 800 pages of text

Who amongst the following is regarded as the creator of the first digital electronic computer? George Boole Alan Turing John V Atanasoff Frederic Calland Williams John von Neumann Solution John Vincent Atanasoff is widely recognized as the creator of the first digital electronic computer. In the late 1930s, along with his graduate student Clifford Berry, he developed the Atanasoff–Berry Computer (ABC) at Iowa State College (now Iowa State University). This machine was completed around 1939–1942. Why the ABC was important: It was the first computing machine to use binary digits (bits) to represent all data. It used electronic vacuum tubes for arithmetic calculations, which made it much faster than mechanical computers. It could solve systems of linear equations, a critical need in engineering and physics. Although the ABC was never fully operational or commercialized like lat...

2020-02 Which of the following is/are TRUE regarding the Von Neumann architecture? Single Instruction, Multiple Data (SIMD) Single Program, Multiple Data (SPMD) Single Instruction Stream, Single Data Stream (SISD) Multiple Instruction, Multiple Data (MIMD) Multiple Instruction, Single Data (MISD) Solution The correct option regarding the Von Neumann architecture is (c) Single Instruction Stream, Single Data Stream (SISD) . The Von Neumann architecture is a foundational computer architecture where both data and instructions are stored in the same memory space. This architecture is characterized by a single processing unit that executes instructions sequentially, one at a time, and processes data from a single stream. This aligns with the definition of SISD (Single Instruction, Single Data) in Flynn's Taxonomy, which categorizes computer architectures based on their instruction and data strea...
