Question 1

A tablet is a pen-based computer that provides the screen capabilities of a PDA with the functional capabilities of a laptop or desktop computer.

Accepted Answer

Tablets are designed to offer the portability and ease of use similar to that of a PDA (Personal Digital Assistant) with the more robust functional capabilities of a laptop or desktop computer, including the ability to run complex applications, browse the internet, and handle multimedia tasks. They typically use a touchscreen (pen-based or finger touch) as the primary input method.

Question 2

Personal digital assistant (PDA) is a small handheld computer that performs simple tasks such as taking notes, scheduling appointments, and maintaining an address book and a calendar. The PDA screen is touch-sensitive, allowing a user to write directly on the screen, capturing what is written.

Accepted Answer

PDAs were designed as handheld devices that could perform various personal management tasks, and their touch-sensitive screens enabled users to interact directly by writing on them, which was a significant feature for note-taking and scheduling.

Question 3

Magnetic medium is a secondary storage medium that uses magnetic techniques to store and retrieve data on disks or tapes coated with magnetically sensitive materials.

Accepted Answer

Magnetic medium is indeed a secondary storage medium that utilizes magnetic techniques for data storage and retrieval on disks or tapes that are coated with materials sensitive to magnetic fields.

Question 4

A workstation computer is similar to a desktop but has more powerful mathematical and graphics processing capabilities and can perform more complicated tasks in less time.

Accepted Answer

Workstation computers are designed for technical or scientific applications, equipped with more powerful CPUs, GPUs, and larger amounts of memory, allowing them to handle complex tasks, simulations, and calculations more efficiently than standard desktops.

Question 5

Memory stick is an older secondary storage medium that uses a strip of thin plastic coated with a magnetically sensitive recording medium.

Accepted Answer

A memory stick refers to a type of flash memory storage device, not a medium coated with a magnetically sensitive recording medium. The description given matches more closely with magnetic tape, not a memory stick.

Question 6

A hard drive is a secondary storage medium that uses several rigid disks coated with a magnetically sensitive material and housed together with the recording heads in a hermetically sealed mechanism.

Accepted Answer

A hard drive (HDD) uses rigid disks coated with magnetic material to store data, and these disks along with the read/write heads are contained within a sealed enclosure to protect against dust and other contaminants.

Question 7

A desktop computer portable enough to fit on a lap or in a bag and has its own power source or battery.

Accepted Answer

A desktop computer is designed to be stationary and is not built to be portable or to have its own battery power source. The description fits a laptop, not a desktop computer.

Question 8

A desktop computer sits on, next to, or under a user's desk and is too large to carry around. The computer box is where the CPU, RAM, and storage devices are held with a monitor on top, or a vertical system box (called a tower) usually placed on the floor within a work area.

Accepted Answer

A desktop computer is designed to be stationary and is indeed too large to carry around easily. It typically includes a computer box that houses the CPU, RAM, and storage devices, with a monitor that can be placed on top or beside it. The system box can be a horizontal case that sits on a desk or a vertical tower that is often placed on the floor.

Question 9

A workstation is a cellular telephone with a keypad that runs programs, music, photos, email, and includes many features of a PDA.

Accepted Answer

A workstation is a high-performance computer designed for technical or scientific applications, intended primarily to be used by one person at a time and typically connected to a local area network. It does not describe a cellular telephone with multimedia and PDA features.

Question 10

A common type of minicomputer is a server and is used for managing internal company applications, networks, and websites.

Accepted Answer

Minicomputers, often referred to as mid-range computers, are smaller than mainframe computers but more powerful than personal computers. They can serve multiple users simultaneously and are commonly used as servers for managing internal company applications, networks, and websites due to their capability to handle significant workloads and support multiple simultaneous users.

Question 11

An input device is equipment used to capture information and commands.

Accepted Answer

An input device is indeed used to capture or enter information and commands into a computer or other processing system, allowing the user to interact with and control it. Examples include keyboards, mice, and scanners.

Question 12

An input device is equipment used to see, hear, or otherwise accept the results of information processing requests.

Accepted Answer

An input device is used to send data to a computer system for processing, not to receive or display the results of information processing. Output devices are used for those purposes.

Question 13

A handheld computer portable enough to fit in a purse or pocket and has its own power source or battery.

Accepted Answer

This description fits the definition of a handheld computer, which is designed to be portable and powered by its own battery, making it convenient for use on the go.

Question 14

A personal computer is a computer that is operated by a single user who can customize the functions to match personal preferences.

Accepted Answer

A personal computer is designed for use by an individual user, not by multiple users in a networked environment, allowing for customization to the user's personal preferences and needs.

Question 15

A desktop computer is an electronic book that can be read on a computer or special reading device. Some are small enough to carry around, while others are the size of a telephone booth.

Accepted Answer

A desktop computer is a personal computer designed for regular use at a single location on or near a desk due to its size and power requirements, not an electronic book.

Question 16

A minicomputer is designed to meet the computing needs of several people simultaneously in a small to medium-size business environment.

Accepted Answer

Minicomputers are smaller than mainframe computers and are designed to serve multiple users simultaneously, making them suitable for small to medium-sized business environments.

Question 17

An appliance is a computer dedicated to a single function, such as a calculator or computer game.

Accepted Answer

An appliance, in the context of computing, refers to a device designed to perform a specific function or set of functions, often with optimized hardware and software for those tasks. Calculators and gaming consoles are examples of such dedicated devices.

Question 18

Adaptive computer devices are input devices designed for special applications for use by people with different types of special needs.

Accepted Answer

Adaptive computer devices are specifically designed to provide accessibility to computers for individuals with various special needs, enabling them to use computers more effectively and comfortably.

Question 19

A megabyte (MB or M or Meg) is roughly 1 million bytes.

Accepted Answer

A megabyte is commonly understood to be equivalent to 1 million (1,000,000) bytes, although in some computer science contexts, it is precisely defined as 1,048,576 bytes (2^20).

Question 20

A tablet computer has a flat screen that uses a mouse or fingertip for input instead of a keyboard. Similar to PDAs, tablet PCs use a writing pen or stylus to write notes on the screen and touch the screen to perform functions such as clicking on a link while visiting a website.

Accepted Answer

Tablet computers indeed have flat screens and primarily use touch inputs (fingertips or stylus) for interaction, including writing notes or navigating websites, rather than relying on a physical keyboard or mouse.
