Multimedia and Mass Storage Installation Paper
How can the computer’s we use every day affect the environment and the people that use them? There are both positive and negative repercussions from using computers in our everyday lives. The computers that we rely on in our daily lives can be dangerous. We nave to De cutlass AT now computers are supposes AT when teen have reached the end of their life cycles. Some of the positive effects of computers on the environment are that we as a society are using less paper and killing fewer trees. We are saving gas by not having to run to the store to purchase items since people can order things online.
This is done on the computer from the privacy of your own home. With computers we are able to measure the changes in the atmosphere and the effects of global warming. Negatively, computers that have been disposed of improperly can lead to harm. Computers have lead in the solder that holds the components in place. This solder can break down over time and seep into the earth and water systems. Lead is poisonous, toxic, and can harm all things that come in contact with it, including plants, animals, and humans. Other elements that are found in computers are mercury, chromium, and nickel.
Computers and their components are not biodegradable so they will remain forever as a pollutant to society. Computers continue to be replaced because people want newer and faster. They will continue to fill out landfills and cause harm to everything until we realize that these systems can be recycled and dispose of properly. Obsolete computers can be recycled at electronic stores that accept them. Consumers are able to send unwanted computers back to the manufacturer to have them refurbished and sold again as such. Computes can be donated to organizations that will provide them to families who cannot afford one on their own.
There are stores like Busty who offer a computer buyback option when you purchase a new computer from them. Within two years of the original purchase of a new computer Busty will purchase your old computer in exchange for a purchase of a new computer. Busty will the properly recycle your old computer in a manner that will not pose any environmental concerns. By doing this there is no longer a threat of the toxins getting into our earth or water systems. Power Supply Protection Computers cannot handle the constant power changes. It will ultimately lead to failure in your computers power supply.
There are a few way to protect your computer so this does not happen to you. A computer power supply has to make up for several things when it comes to the computer power. This includes blackouts, brownouts, surges, sags, and spikes. A blackout is when the power goes out completely and does not turn back on. This is the worst thing that can happen to an individual’s power at home. “An uninterruptible power supply or UPS is an online device that is constantly providing battery power to the computer and being recharged by the wall outlet,” Peach. Com.
Since blackouts do not occur all that often, there are other devices to protect your imputer from power surges and spikes. These devices are in the form of surge protectors. Common surge protectors can protect your computer from the fore mentioned power related issues. A surge protector can protect multiple devices at the same time from the increase of power that enters your house by regulating the power that goes to your computer. If the power is too much the surge protector shuts off the power to the devices and protects them from harm. To protect your computer from under power situations a line conditioner would be recommended.
I Nils would De good Tort noses Tanat nave older willing or noses Tanat eave a lot of devices on and the power fluctuates and the lights tend to dim. The line conditioner will help reduce and remove interference from the electrical lines. This will help to make sure that the computer receives the right amount of power at all times. Computers have to have a certain amount of power in order to operate them correctly. You have to protect that power supply from outside influences that can harm the computers power supply. In doing so, you can save a lot of money and headache in the future by not having to replace the power supply.
Investing in protection for your computer is a wise choice. Downloading Unauthorized Software At one point or another in our lives, we have all downloaded software or files for free from the internet. There are many risks that you are taking in doing this. There are so many ways that a person’s computer malfunctions and downloading software can only be one of them. One of the first risks that I am going to discuss is the possibility of introducing viruses into your computer. A virus can be made to delete files, share information when you are online, and destroy computer parts.
Viruses hidden in software will do whatever they were built to do. They can easily harm the computer and make it impossible to use. Downloading programs can cause other issues beside the viruses. Installing programs for the internet that you have downloaded can slow the computer and the program that down you are trying to run. This means that the program does not respond right when trying to execute commands. Slow running programs can cause the computer to crash or freeze up, making the user have to force a reboot. Installing this program can help resolve this issue.
It is illegal to download software that you do not have a license to download. If a person is caught they could be facing fines, penalties, and possible Jail time. This charge would include software piracy. Not everyone is caught and the consequences could result harmful to yourself financially, and harmful to your computer. If you are downloading unauthorized software at work on a work computer you could face being removed from you Job. You are opening up the business to potential threats from outside the company. Secrets that are contained on computers are now vulnerable.
If this information gets out you could destroy the company. Most companies have policies in place and administrative restrictions that prevent this from happening but they are not completely secure. While there is all sorts of software available for download on the internet, it would be ill advised to download it. You never know what you are going to get besides the software. Some of these programs can hide viruses so well that your anti-virus software cannot detect them until it is too late. The easiest way to prevent these issues is to not download anything that you do not know where it came from.
Section Two Tower Dust, Heat, and Static There are a few natural things that can harm the computer and these include dust, heat, and static. These are all things that happen inside you desktop computer. Cleaning ten Insole AT your computer Is Just as Important as cleaning ten outside your computer. You will have to open the case by removing the screws that hold it in place in order to do this. Locate the two or four screws on the back of your computer that hold the case on.

This will kill the computer and you will have to replace it or a lot of the components because of the overheating ruining the computer parts.
The easiest way to clean the inside of your computer is with a can of compressed air that can be purchased at many superstores. With this method of cleaning the inside of the computer the purpose is to touch the parts of the computer as little as Seibel. You will have a mess to clean up after you are done blowing the computer out. Another method used to clean the inside of the computer is with a cloth designed for cleaning the computer. Micro-fiber and cotton cloths would be anti-static and not harm you r computer. You would simply then wipe down all of the surfaces inside the computer removing all of the dust.
This method requires less clean up from around the computer after you are done cleaning the inside of the computer. Keyboard Cleaning Keeping your keyboard clean will help so that your keys function properly and do tot stick down. This is very aggravating when you are trying to type something and you have hard to push keys or keys the do not come back up after you press them. This is why the keyboard needs to be cleaned from time to time. One of the first things you need to do is to unhook you keyboard from the computer, if it is a wired keyboard.
You will then turn the keyboard upside down and shake it to remove any loose particles from inside the keyboard. While holding the keyboard upside down you can also use a can of compressed air to spray between the keys and remove particles from there. To clean the around the keys, you can use rubbing alcohol and a q-tip or cotton swab to dissolve any liquids that have been spilt inside your keyboard. Use caution with this though, it could discord your keyboard if it is too strong. Test the strength of the alcohol on the back of the computer keyboard or another place where it will not be noticed easily.
After you have tested the alcohol for disconsolation, you can use a cloth or cotton swabs to wipe the keys of the keyboard. You really want to focus on frequently used keys like the shift key, enter key, and the space bar to get them clean. Once you have he keys cleaned to satisfaction you can wipe down the rest of the keyboard. If you are using a wired keyboard you will need to plug it back in to the computer tower. Your Karaoke wall stay Tunneling properly IT you take ten relent steps to Keep it clean. It will also have less germs and appear brand new for years to come.
When you own or work on a computer you know the frustration that you experience when it does not work properly. Imagine if it is caused by something getting spilled in the keyboard. A general rule to follow is to not eat or drink while using your computer. Mouse Cleaning The first thing that you need to do when it comes to cleaning you mouse it to unplug it from the computer. If you are using a wireless mouse, you want to remove the devices batteries before proceeding with the cleaning. This will prevent any static electricity from traveling into the computer tower and damaging the computer.
The mouse is what we use to navigate the computer. Without the mouse working with a computer is hard to do. You can start by wiping your mouse surfaces off with disinfecting wipes. You have to make sure they are not overly wet because any moisture that enters the inside of he mouse can damage it and make it not work when you plug it back in. You never want to spray any fluids directly on the mouse for the same reason. Clean the top of your mouse focusing on cleaning the cracks and slots on the top. Make sure that you clean the space between the mouse wheel and the buttons of the mouse.
If there is debris in the spaces between the wheel and the mouse buttons, turn the mouse upside down and roll the mouse wheel to try to dislodge it. You might have to shake the mouse to get the debris to fall out. While the mouse is upside down you can clean the bottom of the mouse. Use a q- IP to clean out the area where the optical eye (red light) is at on the mouse. Ensure that this area is clean so that the mouse can track the motions properly. If you have an older mouse that has a ball in the bottom of it you will have to remove the ring around the ball.
There are arrows on the bottom of the mouse so you know which way to turn the disk. Once you have the disk out of the bottom you can remove the ball from the mouse. You will see a couple of rollers inside of it. Clean these rollers off with a q-tip so that there is nothing left on them. You will then want to clean the ball itself off with a rag of some sort. Once you have done this you can drop the ball back into the bottom of the mouse. You will then replace the retaining ring to hold the ball in place. You can then plug the mouse back in to the computer or put the batteries back in it and turn it on.
The mouse is then clean and ready to use again. Cleaning Your Monitor If you need to clean your dirty monitor or display you have to take care if it is a LED or LCD screen. The older CRT screens are glass and can be cleaned in the same manner you would clean any other glass around your house. The LCD and LED screens are more sensitive and can be easily damaged if you do not take some precautions. If this is done correctly, it can be done in less than five minutes.

You still have to press with caution on these devices though. If the simple cloth is not cutting the oil and dirt on the monitor you can dampen he cloth with a distilled water and white vinegar mix. This mix should be equal amounts of water and vinegar to prevent streaks.
The vinegar will help cut the tough oil spots on most of your devices. Companies have made special cleaner that are for use with LCD and LED screens. If you do not want to go out and buy this special cleaner the water vinegar mix works just as well. Do not use products that contain ammonia in them because this can damage your screen. Ammonia can discord the screen and cause permanent damage. Do not use toilet paper or paper towels on you monitor. This can scratch the trials that are on the monitor that give it the anti-glare feature. Once this special coating is gone it cannot be replace.
Your monitors’ picture will also look different if this coating is scratched. It could even be distorted looking if you Just scratch areas of the screen.
