Reset Power Supply Some power supplies will have a switch on them, and you can just flip the switch off and then back on again to reset the power. You can try doing this with or without the power cable plugged in.

Following is a simple flowchart to help you zero in on common power supply–related problems:

1. Check AC power input. Make sure the cord is firmly seated in the wall socket and in the power supply socket.
2. Check DC power connections.
3. Check DC power output.
4. Check installed peripherals.

To summarize, high quality PSUs can fail for the following reasons:

• Broken MLCC components.
• Long mounting PCB screws.
• Damaged ICs and FETs because of soldering-wave issues.
• Careless soldering jobs/repairs.
• Cracked PCBs.
• High inrush currents.
• Creepy-crawlies.
• High surge voltages.

Most likely your system will shut down at some point if your PSU is too weak. It would help to know your current PSU model and system specs. A 1060 uses very little power even at peak draw. You’ll be fine, wattage wise.

What is a symptom of a failing power supply? The computer sometimes does not turn on. It could also cause a computer to reboot unexpectedly. A technician helps a customer to add a new 2 GB RAM module to a workstation that currently has one 2 GB RAM module installed.

Which two types of data should be backed up before troubleshooting a computer for a customer? (Choose two.) Explanation: Only customer created data is necessary for backup as a precaution to the troubleshooting process.

The purpose of a mains power supply is to convert the power delivered to its input by the sinusoidally alternating mains electricity supply into power available at its output in the form of a smooth and constant direct voltage.

What task should be completed before escalating a problem to a higher-level technician? Verify full system functionality and, if applicable, implement preventive measures.

What is the most important reason for a company to ensure that computer preventive maintenance is done? Preventive maintenance helps to protect the computer equipment against future problems. A technician opens up a PC to work on it, and finds that it is very dusty inside.

What are three types of power issues that a technician should be concerned about? (Choose three.)

• blackout.
• flicker.
• brownout.
• spike.
• spark.
• fuzzing. Explanation: Power issues include increases, decreases, or sudden changes in power and include the following: Spike. Surge. Fault. Blackout. Sag/dip. Brownout. Inrush Current.

Bluetooth network technology

Which two devices are commonly powered by PoE? (Choose two.)

• access point.
• core switch.
• IP phone.
• modular switch.
• router. Explanation: Compact switches, APs, and IP phones can be powered by a PoE-enabled switch. Routers and modular switches require a large amount of energy and cannot be powered through an Ethernet cable.

The distinguishing features of WAN are WANs have a large capacity, connecting a large number of computers over a large area, and are inherently scalable. They facilitate the sharing of regional resources. They provide uplinks for connecting LANs and MANs to the Internet.

technology adoption finds that 73 percent of the 37,000 respondents claim the mobile phone is the electronic device they use the most.

Here is the list of the top 9 new and trending technologies:

• Artificial Intelligence (AI) and Machine Learning.
• Robotic Process Automation (RPA)
• Edge Computing.
• Quantum Computing.
• Virtual Reality and Augmented Reality.
• Blockchain.
• Internet of Things (IoT)
• 5G.

Whether it’s practical (like washing machines, tumble dryers, refrigerators, cars, flooring materials, windows, or door handles) or for leisure (like televisions, Blu-ray players, games consoles, reclining chairs, or toys), all these things are examples of technology.

In general, when technology attempts to solve problems of matter, energy, space, or time, it is successful. When it attempts to solve human problems of the mind, communication, ability, etc.

A wide area network (also known as WAN), is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.

Difference between a LAN and a WAN

Advantages of a wide area network (WAN)

• Covers large geographical area:
• Centralized data:
• Get updated files and data:
• A lot of application to exchange messages:
• Sharing of software and resources:
• Global business:
• High bandwidth:
• Distribute workload and decrease travel charges:

While WANS provide numerous advantages, they have their share of disadvantages. As with any technology, you need to be aware of these downsides to make an informed decision about WANS. The three most critical downsides are high setup costs, security concerns, and maintenance issues.

The further the distance, the slower the network. One of the big disadvantages to having a WAN is the cost it can incur. Having a private WAN can be expensive. A WAN connection is generally harder to set up, and there are many creative ways to do so.
