The correct answer for this question is 'Digital technology' because modern computers operate using binary code, which is a system of ones and zeros that represent data. This binary code is processed by digital components such as transistors and integrated circuits, which are fundamental to the functioning of computers. Therefore, the foundation of present-day computers lies in digital technology.
The correct answer for this question is 'Glitch' because in computer jargon, a glitch refers to a temporary fault or malfunction in a system. This term is commonly used to describe unexpected errors or problems in software or hardware, making it the appropriate alternative for 'bug' in this context.
The correct answer for this question is 'Mainframes' because mainframes are known for their ability to handle multiple users simultaneously through time-sharing. This allows small businesses to save costs by using a single processing unit to link several users, maximizing efficiency and reducing the need for multiple individual systems.
The correct answer for this question is 'Optical input device' because a light pen is a type of input device that uses light to interact with a computer. It is typically used to select objects on a screen by pointing directly at them. This makes it an optical input device that relies on light for its functionality.
The correct answer for this question is 'RAM' because RAM (Random Access Memory) is a type of memory that is volatile, meaning that it loses its data when the power is turned off. This is in contrast to non-volatile memory, such as hard drives, which retain data even when the power is off.
The correct answer for this question is 'C. Processing' because RAM, Cache, and Registers are all used to temporarily store data and instructions during the processing of tasks by the computer. These components play a crucial role in the overall processing speed and efficiency of the computer system.
The correct answer for this question is 'CPU' because the Central Processing Unit (CPU) is the main component of a computer that controls and executes instructions from software programs. It is responsible for performing calculations, processing data, and managing the overall operation of the computer system. Therefore, the CPU is the unit that controls all parts of the computer.
The correct answer for this question is 'Disk' because a disk is a storage medium that is in the form of a circular plate. Disks are commonly used in computers and other electronic devices to store data and information. The circular shape of a disk allows for data to be stored and accessed efficiently.
The correct answer for this question is 'Hard Disk Drive' because HDD is a commonly used acronym in technology to refer to the storage device that uses magnetic storage to store and retrieve digital information. This term is widely recognized in the field of computing and accurately describes the function of the device.
The correct answer for this question is 'Mainframes' because mainframes are powerful computers that can support multiple users simultaneously, allowing small businesses to save costs by using a single processing unit to link several users. Mainframes are designed to handle large amounts of data and complex processing tasks efficiently, making them ideal for multi-user systems in small businesses seeking cost savings.
