What class of computers are known as midrange computers?
Correct Answer
B. MinicomputerÂ
Explanation
Midrange computers are known as minicomputers. These computers are smaller and less powerful than mainframe computers but more powerful than microcomputers. They are typically used in small to medium-sized businesses or for specific applications that require more processing power than a microcomputer can provide. Minicomputers are capable of handling multiple users and running complex software, making them suitable for tasks such as scientific research, data analysis, and network management.
2.
Which of these is not a type of stationary computer?
Correct Answer
C. Laptop
Explanation
A laptop is not a type of stationary computer because it is designed to be portable and can be used on the go. Unlike stationary computers such as workstations, desktop computers, and gaming computers, laptops are compact and lightweight, allowing users to carry them around and use them in different locations. Stationary computers, on the other hand, are typically larger and meant to be used in a fixed location. Therefore, a laptop does not fit the definition of a stationary computer.
3.
When were nettops introduced?
Correct Answer
D. 2008
Explanation
Nettops, which are small, low-cost desktop computers, were introduced in 2008. This marked the emergence of a new category of computers that were designed to provide basic computing functionality at an affordable price. Nettops were particularly popular for tasks such as web browsing, email, and light productivity work. Their introduction in 2008 coincided with the growing demand for compact and budget-friendly computing devices, and they provided an alternative to traditional desktop computers for users with basic computing needs.
4.
Which of these organizations introduced nettops?
Correct Answer
B. IntelÂ
Explanation
Intel introduced nettops. Nettops are a type of small, low-cost desktop computers designed for basic internet and computing tasks. Intel developed and introduced nettops as a response to the growing demand for affordable and energy-efficient computing devices. These compact machines offer basic functionality, such as web browsing, email, and multimedia playback, making them suitable for casual users and those with simple computing needs.
5.
When was Dynabook first described?
Correct Answer
B. 1972
Explanation
The correct answer is 1972. The Dynabook was first described in 1972.
6.
What are netbooks called?
Correct Answer
A. MininotebooksÂ
Explanation
Netbooks are a type of small, lightweight, and inexpensive laptops that are designed for basic tasks such as web browsing, email, and word processing. They are often referred to as "mininotebooks" due to their compact size and portability. The term "subprobooks" and "disc books" do not accurately describe netbooks, and "optical books" is not a commonly used term for this type of device.
7.
Which of these use a touchscreen display?
Correct Answer
A. Tablet
Explanation
A tablet uses a touchscreen display as its primary input method. Unlike a stylus, which is a tool used for drawing or writing on a touchscreen, a tablet itself has a built-in touchscreen display that allows users to interact directly with the device by tapping, swiping, or pinching on the screen. On the other hand, a printer and netbooks do not typically have touchscreen displays as they rely on other input methods such as buttons or keyboards.
8.
Which of these can be operated using a stylus pen?
Correct Answer
A. Tablets
Explanation
Tablets can be operated using a stylus pen because they have touch screens that are designed to be responsive to touch inputs, including those made by a stylus pen. Stylus pens provide more precision and control compared to using fingers, making them ideal for tasks that require accurate drawing, writing, or navigating on the tablet's screen. This feature is not commonly available in pocket computers, laptops, or desktops, which typically rely on keyboards and trackpads or mice for input.
9.
Which of these is an external part of a personal computer?
Correct Answer
A. Central processing unit
Explanation
The central processing unit (CPU) is an external part of a personal computer. It is responsible for executing instructions and performing calculations. The CPU is typically housed in a separate unit or chip that is connected to the motherboard and other components of the computer. It is considered an external part because it is not directly integrated into the motherboard or other internal components of the computer.
10.
Which of these provides memory for computers?
Correct Answer
A. Disc drives
Explanation
Disc drives provide memory for computers. Disc drives, also known as hard disk drives or HDDs, are storage devices that store and retrieve digital information using magnetic storage and rotating disks. They provide long-term storage for data and programs on a computer. Random access memory (RAM) and read-only memory (ROM) are different types of computer memory, but they do not provide memory for computers in the same way that disc drives do. The motherboard is the main circuit board of a computer, but it does not directly provide memory.
