General computer cleaning Tips

Below is a listing of general tips that should be taken when cleaning any of the components or peripherals of a computer as well as tips to help keep a computer clean.

1. Never spray or squirt any liquid onto any computer component. If a spray is needed, spray the liquid onto a cloth and then use that cloth to rub down the component.
2. You can use a vacuum to suck up dirt, dust, or hair around the computer on the outside case. 3.However, do not use a vacuum for the inside of your computer as it generates a lot of static electricity that can damage the internal components of your computer. If you need to use a vacuum to clean the inside of your computer, use a portable battery powered vacuum designed to do this job or try using compressed air.
4. When cleaning a component or the computer, turn it off before cleaning.
5. Be cautious when using any cleaning solvents; some individuals may have allergic reactions to chemicals in cleaning solvents and some solvents can even damage the case. Try to always use water or a highly diluted solvent.
6. When cleaning, be careful not to accidentally adjust any knobs or controls. In addition, when cleaning the back of the computer, if anything is plugged in, make sure not to disconnect any of the plugs.
7. When cleaning fans, especially the smaller fans within a portable computer or laptop it's suggested that you either hold the fan or place something in-between the fan blades to prevent it from spinning. Spraying compressed air into a fan or cleaning a fan with a vacuum may cause damage or back voltage to be generated.
8. Never eat or drink around the computer.
9. Limit smoking around the computer.

Some thing about Abacus the first calculating device

Now let we start from the abacus where we ended. Later on a little development was made by John Nappier who made Napier Bone which were made by the bone of the some animal. In which numbers were stroked. A mathematician Herman Hollerith developed the tabulating machine that used to do some simple calculation like addition, subtraction and multiplication. Later on many other calculating device were invented. The first computer which was invented by John Von was Mark 1st. It was too bigger in size and used to use large amount of space and mile of cables. It used the valves or Vacuum tubes as its main component in it. It even used large capacity of the electricity. It consumes a full room space and two many man power to use it. The main component vacuum tube was invented by Lee Dee Forest during the period of 1956 to 1963 AD. This was something about first generation computer.

Level 1 of computer

This is a saying that to know something we have to know its history. So what is the history of the computer? First father of computer is well known to charles babbage who developed first calculating device known as analytical engine and difference engine. Several people like lady ada, herman hollirith and other great scientist have envolved in it. At first there were no computer neither any calculating machine. Our forefather used to use pebbles or dry sticks to calculate. Later on abcus ( the first calculating device) was built on may be on 2000 bc or nearer. Abacus which was divided into three sector - heaven, mid bar, earth. These are some information about the begining of the computer history.

Some Use Of Computer

Although the computer got the bad defect but also contain the good things such as it can be used as education purpose to develop the mind and every student can take their time to make their mind sharp through this and also every work belonging in development of the country can be fulfill with the help of computer. As we all know that this age belongs or direct or indirectly connected with the computer. As the computer we know that have been developed to that stage where it can work in every field weather that is worker or an accountant. Although  not having its own intelligence it does have accuracy in it.

Some Effect And Defect Belong To Computer

                                                           

Computer a dumb machine has some of the defect and also some of the good effect. Some defect like it is making the people little bit lazy. It does maximum of the work like calculation and other which is causing the people to be dependent. And due to the games and other entertaining things some of the children and adults have spoil their habits. This computer is only good for the countries which don’t have the problem of light not for the countries having problem of light. And one of the most effective defect of the computer is it doesn’t contain its own intelligence, it can’t do any thing itself. It doesn’t contain its own thinking ability so when some wrong data are manually entered then it can’t be corrected automatically. These are some defect that a dumb machine computer poses which have some bad impact on human world.

Computer the machine that uses our instruction to workout. In my view main thing about the computer is that it have some similarity with human due to its own creation with a human mind. As computer got the fixed memory as the human too got the memory of brain only limited. All the computer got to restart to make itself to refresh. And the human too need to sleep to refresh. Computer got the processor to control whole over the computer and as same there is heart for the human to control all over the human body. We can take our eyes as the graphic of computer for the human. Only one things that differs us from the computer is that their memory can be formatted but our memory cant be formatted and some common differ like versatile, dilligence and fast but also computer cant be compared with human cause it is a dumb machine and cant work with us. This is the some differ and the mostly common similarity between computer and human.

Computer

       Computer as we know that is very commonly used mechanical thing. First we may start with its defination that it is an electronic device which takes input from the user from any kind of input device like keyboard, mouse, scanner and so on and gives an output to the user as result. For the computer we may elaborate it with a full form of Commonly Operatable Machine Particularly Used for Trade, Education and Research. This machine is mostly commonly used now days in every form of work like mostly for the educational purpose, for researching in scientifical or geographical. This machine is used for the simplicity, fast and for most reliable purpose. This is mostly said that computer are far faster than human in most of the work but only the bad sector that belong to the computer is that they cant think like human neither can have any emotions.
