The Story Of IT Essentials Chapters 1 To 10

Explanation
The correct answer is "Writing." In the laser print process, writing refers to the process of creating an image or text on a photosensitive drum using a laser beam. This is the first step in the actual printing process, where the laser beam selectively charges areas on the drum, creating a latent image. The charged areas will attract toner particles in the next step, which will then be transferred onto the paper to create the final printed output.

Explanation
The star topology is characterized by each host being connected to the central device with its own wire. In this topology, all communication between the hosts is done through the central device, which acts as a hub. This allows for easy management and troubleshooting of the network, as well as providing better performance and scalability compared to other topologies.

Explanation
Isopropyl alcohol is commonly used to clean electronic components, including RAM sticks. RAM sticks can accumulate dust, dirt, and oils over time, which can affect their performance. Isopropyl alcohol is a safe and effective solvent that can remove these contaminants without causing damage to the delicate circuitry of the RAM stick. Therefore, cleaning RAM sticks with isopropyl alcohol helps to maintain their optimal functioning.

Explanation
The correct answer is 19. This is because a standard HDMI connector has 19 pins, which are used for transmitting audio and video signals between devices.

Explanation
Contrast is the correct answer because it refers to the ratio of light to dark in an image or visual display. It measures the difference between the brightest and darkest parts of an image, creating a sense of depth and visual interest. By adjusting the contrast, one can enhance the visibility and clarity of an image. Brightness, sharpness, Ken's head, and position do not directly relate to the ratio of light to dark, making them incorrect options.

Explanation
The Molex connector is commonly used to provide power to various components in a computer system, including optical drives. It is a type of electrical connector that consists of multiple pins arranged in a rectangular housing. The Molex connector is known for its reliability and compatibility with a wide range of devices, making it a popular choice for powering optical drives.

Explanation
SATA data cables typically have 7 pins.

Explanation
The given statement describes the ability of a computer to run multiple applications simultaneously. This is known as multitasking, where the computer's operating system efficiently allocates resources and time to each application, allowing them to run concurrently. Multitasking enables users to switch between different applications seamlessly and enhances the overall productivity and efficiency of the computer system.

Explanation
Task Manager allows you to view all applications that are currently running on your computer. It provides a detailed overview of the processes, services, and performance of your system. You can use Task Manager to monitor the CPU and memory usage, end unresponsive applications, and manage startup programs. It is a powerful tool for troubleshooting and optimizing your computer's performance.

Explanation
The dimensions of a PC Card (or Brown) are 85.6 x 54 mm.
