A technician notices a burning smell coming from a desktop computer immediately after powering it on. What is the MOST likely cause of this smell?
What is The power supply is malfunctioning.
A malfunctioning power supply can lead to overheating or electrical issues, resulting in a burning smell.
When traveling to a remote location with limited cellular coverage, what feature should a user enable on their mobile device to share internet access with their laptop?
What is Hotspot?
To share internet access with a laptop in a remote area with limited cellular coverage, the user should enable the "Mobile Hotspot" feature on their mobile device. This functionality allows the mobile device to act as a portable router, providing internet access to other devices, such as laptops, through Wi-Fi or a tethered connection.
Among the following options, which is a connection-oriented protocol?
A. DHCP
B. TFTP
C. HTTPS
D. DNS
What is HTTPS?
HTTPS is a connection-oriented protocol that operates over TCP (Transmission Control Protocol). It provides a secure and encrypted communication channel between a client and a server, commonly used for secure web browsing.
For a graphic designer's workstation with a motherboard that supports quad-channel memory, how many RAM modules should the technician ideally install to maximize performance?
What is four RAM modules?
Quad-channel memory configurations take advantage of the four memory channels available on the motherboard, providing increased bandwidth for data transfer and better performance, which can be beneficial for tasks such as graphic design.
In which cloud service model do users rent virtualized hardware resources over the internet?
What is Iaas.
In IaaS, users have access to virtualized computing resources, including virtual machines, storage, and networking, without the need to invest in or manage physical hardware.
After a system update, a user notices that one of their hard drives is not displayed in the operating system. This could be due to:
What is A drive letter conflict.
A drive letter conflict could occur during the update process, leading to the drive not being recognized by the operating system. Checking the Disk Management tool in the operating system to resolve any conflicts and assign a proper drive letter to the affected hard drive would be a recommended troubleshooting step.
To share files between a mobile device and a computer without using any cables, which feature should a user enable?
What is "Bluetooth" or "Wi-Fi Direct"?
To share files wirelessly between a mobile device and a computer without using cables, the user should enable "Bluetooth" or "Wi-Fi Direct" features. Both options allow for wireless communication between devices, facilitating the transfer of files without the need for physical connections.
In a SOHO (Small Office/Home Office) network, what is the typical purpose of the default gateway?
what is Routing/Communicating outside the local network?
It serves as the point of exit and entry for traffic between the local network and external networks, such as the internet. The default gateway is crucial for directing network packets to their intended destinations, allowing devices within the local network to communicate with devices outside the network.
