LET’S TALK ABOUT UPS (Uninterruptible Power Supply)

One of the most important investments you can make when you purchase a computer, is an UPS. Protect your hardware and data loss; increasing user productivity. When the electrical current going to your device is not steady, it can have dire consequences for your PCs and home entertainment systems. Common issues relating to voltage include blackouts, brownout, noise, spikes, and power surges. Mother Nature will have her moments; it’s just a fact of life.

NOTE: this list is an incomplete list and suggested brands, depends and may varies on your country.


HOW DOES IT WORKS
Before we define the issues related to voltage irregularity, let’s find out what a UPS is and how it works. A UPS is a device that provides consistent backup power during inconsistent power issues. The UPS can protect both data and the computer equipment connected to it by stabilizing the voltage passing through. A UPS comes in a range of sizes and models that target different types of equipment. Some of these include the UPS itself, Surge suppressor, and SPS. Knowing the right one to use is essential for the protection of the equipment you use.


POWER PROBLEMS, HOW MANY?

BLACKOUT: Also called a “power cut” can happen when a transformer is damaged or a downed power line. Software improvements over the years have improved when situations like this occur. If you used earlier Windows 95 or 98, you might remember that when a power outage occurred, and you started up your PC, it would perform a diagnostic test. With the introduction of Windows NT and NTFS, Windows recovers from the event easier.


BROWNOUT: This happens when there is an overload of electrical circuits. If you have a lot of electrical equipment connected and in use at the same time, this can trigger a brownout resulting in a loss of power. The issue usually lasts for a short period, but it can cause damage to your device.


NOISE: Commonly caused by interference from lightning and generators; resulting in unclean power going to your devices. It can cause the operating system and applications to malfunction and possibly corrupt files.


SPIKE: A sudden increase in voltage lasting only a short time. Common causes of this are lightning or restoration of your power after a widespread outage. When this happens, what I normally do is unplug all my electrical equipment. When the power returns, I wait a bit for the voltage to normalize before I reconnect the equipment. Some electric companies will notify you if there is going to be a planned outage for maintenance.


POWER SURGE:  A dramatic increase in voltage caused by household appliances such as a refrigerator or air conditioners. Surges last a very short time, but can cause significant damage to computer components.


WHAT HAPPENS IF DON’T?
You might notice, in the descriptions of these different voltage disturbances, a lightning storm is usually the biggest threat to your equipment. What exactly does the lightning do that makes it hazardous to your equipment? When lightning strikes a transformer, it can trigger a powerful surge, which travels instantaneously through the wiring going to your house. The surge moves to your computer from the outlet or data lines. The first component that usually dies in your PC is the motherboard. This effect can also trigger a wave of other voltage issues that damages other components in your PC, like the hard drive and RAM.



HOW AND WHAT TO CHOOSE
Protecting your equipment is not a one size fits all approach. There are many solutions available on the market that target different environments, including a home, office, or a large data center. Here is a list of what to look for when purchasing a UPS for the home.

  • A UPS is a significant investment, ensure there is a lifetime warranty included with your purchase. I have owned a UPS since 2005, even though the battery died a few years ago, I was able to get a replacement battery at a small fraction of the cost purchasing a new one.
  • Supports up to eight outlets for various equipment. I have two computers on all the time; some UPS equipment will include one battery backup in addition to surge protection; while having extra outlets with only surge protection. In scenarios like this, I will only keep the most important device connected to the battery outlets on the UPS.
  • The backup power that’s immediate in case of a power outage.
  • Your UPS should support protection of other devices such as a network, serial port and data connections.
  • Complete surge suppression that filters out an unreliable voltage that could damage equipment.
  • Site wiring fault indicator to ensure that your equipment is properly grounded.
  • Noise filtration preventing data corruption.
  • Other features and functions to look for including a battery replacement indicator, battery management, intelligent features such as automatic save and shutdown. This might be available only on more expensive models.
Home computing has evolved over the years; it is not unusual for some users to own a home server and other equipment such as a Network Attached Storage (NAS) device. For such configurations, investing in a UPS will require more research on your particular needs. The most obvious being the need for a more a powerful UPS that can handle the demands.

A media server works similarly to a file server used in an office. They are constantly saving, retrieving or processing information like streaming to your smart TV or mobile devices. Such events can lead to a catastrophic loss of data if a power outage occurs. For such setup’s, you should first consider investing in a UPS with options such as battery replacement, the ability to hot swap a battery, and intelligent battery features. Integration with your backup tools is also a function of the UPS you should look at getting.

SAMPLE IMAGE, NOT A VALID OR PUBLICITY IMAGE

FUNCTIONS, FUNCTIONALITY AND OTHER ASPECTS
Having a UPS will prevent damage to your equipment, but predicting when such events might occur is usually beyond your control. By having the option to gracefully shutdown provides protection against data loss. These features are commonly available in the accompanying software that comes with your UPS. Make sure you check for the follow features when making your purchase:

  • Automatic shutdown
  • User notification of power loss
  • Customization shutdown commands
  • Conservation mode.
  • Battery replacement warning.
  • Management tools: status display, runtime, event log, remote management via the web or remote computer
  • Environmental: temperature, humidity
Of course, all the mentioned options before, depends on your BUDGET. 

Ask yourself How much does your information and data COST?



OPERATING YOUR UPS BACKUP PROPERLY
Using your UPS effectively is important. Some users might believe, a UPS means the fun will never stop, meaning, you can keep playing, listening to songs, or just leave the computer running idle. Nope. What you should do is use the opportunity to shut down the equipment gracefully. Some UPS devices will provide up to 1 hour of backup power. Use this time to shut down and power off all equipment.

One device you should never plug into a UPS is a printer. Doing so can cause the printer motor to burn up. A printer will queue whatever jobs there are to print. When the power returns, it normally resumes printing. A simple surge protector should be enough.

Owning computing equipment is a major investment and protecting it should be a top priority. 




NOTE: This article is for a desktop computer, a laptop does NOT NEED a UPS and only depends if the laptop has a DOCKING STATION and this will provide AC to all components attached. Example:
WHAT ABOUT SURGE PROTECTORS
At the very minimum, you should definitely be connecting your computer and home entertainment devices to a surge protector. A surge protector doesn’t provide any power backup, but will protect your equipment from damage.



PERSONAL EXPERIENCE: one time in a company, we were running out of budget... and what we do was to share a UPS. How? simple, just plug 2 CPU without monitors and from the end of the software, configure ALL to save every minute. once you are in a power outrage, you can turn off the computer pushing the power button and everything you were working, gonna be save. Of course, this is not a solution for professionals, but sometimes requires other "technics".

Is not a smart and quite solution, but works until you can add/replace UPS.

REASONS TO REPLACE YOUR COMPUTER FAN AND HEATSINK

REASONS TO REPLACE YOUR COMPUTER FAN AND HEATSINK A computer's fan and heatsink are two of its most important components. The primary role of both is to cool down the processor and keep it from overheating. A laptop or notebook does not have to be outside in hot, humid weather to overheat. In fact, even if a computer is kept away from extreme heat altogether, it can still overheat. That is because a computer's processor is responsible for processing information and giving instructions to other components in the computer. A processor can get very busy as a result, especially when it is running multiple programs simultaneously. As a result, it heats up, and if there is nothing to cool it down, it can malfunction and break down, costing the owner hundreds or even thousands of dollars. This is why a good fan and heatsink are necessary. The more demand placed on the processor, the more effective the fan and heatsink must be. This guide identifies five issues

LET’S TALK ABOUT PC AUDIO SPEAKERS Computer speakers are one of those PC accessories that are almost essential; and you can spend anywhere from $10.00 to $1,000.00 for quality PC speakers, depending on your budget.   There are tons of tons of speakers with features and different prices as we know. But as I always say: WHAT and HOW is what I am looking for. For sample: I have this one in my office and works properly, the only disadvantage is that has no RADIO and only can be played with micro SD and plugged to my computer. And only pay like $20-$25. USB charged and the battery longs for 6 hours. https://www.energysistem.com/en/products/music_box/music_box_series_/42198-energy_mini_music_box_z100_r_black Here there is some thoughts and share some personal ideas about this topic.

LET’S TALK ABOUT - NETWORK FORENSICS

LET’S TALK ABOUT - NETWORK FORENSICS BASIC CONCEPT Network forensics is a sub-branch of digital forensics relating to the monitoring and analysis of computer network traffic for the purposes of information gathering, legal evidence, or intrusion detection. Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. Network traffic is transmitted and then lost, so network forensics is often a pro-active investigation. Network forensics generally has two uses. The first, relating to security, involves monitoring a network for anomalous traffic and identifying intrusions. An attacker might be able to erase all log files on a compromised host; network-based evidence might therefore be the only evidence available for forensic analysis. The second form relates to law enforcement. In this case analysis of captured network traffic can include tasks such as reassembling transferred files, searching for keywor
