- E.
Storage Device
Correct Answer
A. RAMExplanation
RAM stands for Random Access Memory. It is a type of computer memory that stores data that is currently being used by the computer's operating system, applications, and processes. It is a volatile memory, meaning that it loses its data when the computer is powered off or restarted. RAM is used to temporarily store data that is needed for immediate access by the CPU, such as program instructions and data that is being actively processed. It allows the computer to quickly access and manipulate data, which can improve overall system performance.Rate this question:

Correct Answer(s)
B. Provides backup power from an internal battery
E. Gives the user time to safely shut down the computer if the power failsExplanation
A UPS (Uninterruptible Power Supply) provides two functions that a surge protector does not. Firstly, it provides backup power from an internal battery, ensuring that the computer remains powered on even during a power outage. Secondly, it gives the user time to safely shut down the computer if the power fails, preventing any data loss or damage to the system. These two functions make a UPS more reliable and effective in protecting the computer from power-related issues compared to a surge protector.Rate this question:

What is the purpose of the ASCII code ?
- A.
Translates bits into bytes
- B.
Interprets graphics digitally
- C.
Translates digital computer language into binary language
- D.
Represents letters, characters, and numbers with bits
Correct Answer
D. Represents letters, characters, and numbers with bitsExplanation
The purpose of the ASCII code is to represent letters, characters, and numbers with bits. ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns a unique numerical value to each character, including letters, digits, punctuation marks, and special characters. These numerical values are then represented using bits, allowing computers to store, transmit, and interpret text-based information.Rate this question:

Why do servers often contain duplicate or redundant parts ?
- A.
Servers require more power and thus require more components.
- B.
Servers should be accessible at all times.
- C.
Servers can be designed as standalone towers or rack mounted.
- D.
Servers are required by networking standards to have duplicate parts.
Correct Answer
B. Servers should be accessible at all times.Explanation
Servers often contain duplicate or redundant parts because they need to be accessible at all times. Having duplicate parts ensures that if one component fails, there is a backup in place to maintain the server's functionality. This redundancy helps minimize downtime and ensures continuous access to the server's resources and services.Rate this question:

What can be used to prevent electrostatic discharge (ESD) ?
- A.
Dry and non humid conditions
- B.
Carpeted floor
- C.
Grounding strap
- D.
Uncluttered work space
Correct Answer
C. Grounding strapExplanation
A grounding strap can be used to prevent electrostatic discharge (ESD) by providing a path for the electrical charge to safely dissipate into the ground. This helps to prevent the build-up of static electricity on a person or object, reducing the risk of ESD damage to electronic components. Dry and non-humid conditions, carpeted floors, and uncluttered workspaces may also help to minimize the risk of ESD, but a grounding strap is specifically designed for this purpose.Rate this question:

If a peripheral device is not functioning, what are three things you should do to solve the problem ? (Choose three.)
- A.
Use the testing functionality on the peripheral itself, if available.
- B.
Verify that all cables are connected properly.
- C.
Disconnect all cables connected to the computer except those connected to the peripheral.
- D.
Ensure that the peripheral is powered on.
- E.
Reload the computer operating system.
Correct Answer(s)
A. Use the testing functionality on the peripheral itself, if available.
B. Verify that all cables are connected properly.
D. Ensure that the peripheral is powered on.Explanation
To solve the problem of a non-functioning peripheral device, the first thing you should do is use the testing functionality on the peripheral itself, if available. This will help identify any issues with the peripheral itself. Next, verify that all cables are connected properly to ensure there are no loose or disconnected connections. Finally, ensure that the peripheral is powered on, as it may not function if it is not receiving power. Reloading the computer operating system is not necessary in this situation and may not solve the problem.Rate this question:

Download and install the most current driver.
- B.
Connect the peripheral using any cable and any available port on the computer.
- C.
Connect the peripheral using an appropriate cable or wireless connection.
- D.
Test the peripheral on another machine before installing it on the one where it will be used.
- E.
Check the computer documentation to see if the peripheral vendor is compatible with the PC vendor.
Correct Answer(s)
A. Download and install the most current driver.
C. Connect the peripheral using an appropriate cable or wireless connection.Explanation
When installing a peripheral device, it is important to perform two steps. Firstly, downloading and installing the most current driver is necessary to ensure that the device is compatible with the computer and can function properly. Secondly, connecting the peripheral using an appropriate cable or wireless connection is essential for establishing a reliable connection between the device and the computer. These two steps ensure that the peripheral device can be successfully installed and used on the computer.Rate this question:

In newer operating systems, how are system resources assigned by default when components are installed ?
- A.
Manually assigned by the operating system
- B.
Manually assigned by the administrator
- C.
Statically assigned by the component to a preset resource
- D.
Dynamically assigned between the component and the operating system
Correct Answer
D. Dynamically assigned between the component and the operating systemExplanation
System resources are assigned dynamically between the component and the operating system in newer operating systems. This means that the operating system and the component work together to allocate resources as needed, rather than having them manually assigned by the operating system or the administrator. This allows for more efficient and flexible resource allocation, as resources can be allocated and reallocated based on the current needs of the system.Rate this question:
