We all use computers in our every day activities. So many people these days use computers more often than using regular papers especially in offices. Due to the ways computers help so many people to be more efficient and effective, so many people now prefer to use computers more regularly than before. Keeping track records, doing more calculations, data processing, composing and even chatting are just few of the main reasons while most people these days prefer to use there computers more often than using normal paper works especially in most offices.

In our present life, every one must have some basic knowledge about computer. But if there is someone who is unable to operate a computer, then he can take part in basic computer learning programs easily which are accessible online and offline. Individuals who are unable to attend regular classes at some college or school, can benefit from the Internet or some offline computer learning programs. Some aged people feel embarrassed in joining classes at schools or colleges with young students so they want to master their course at home.

It is not hard to start your basic computer skills learning, because it is very simple to learn and master. There are many issues that one should keep in mind while selecting a useful source for him or her to obtaining basic computer skills. In the process of basic computer learning from home all the lessons or lectures should be in video format, because it would leave a strong impact on the learner. And the person who is delivering the lecture should be experienced and should teach in simple and easy language. The teacher should not be seen as speaking computer himself.

The teachers’ system of teaching should be interesting and simple to follow because it will create interest of the learner in learning basic computer skills faster. The knowledge of the teacher should be perfect and good because if he don’t have complete knowledge of computer himself, then it would be tough to handle students who are totally strange with computers. There should not be any kind of pressure on the students, as this can frustrate the students. The learning environs should be good and there should be some good materials to practice with or little interesting assignments for the students.

Coordinated Universal Time (UTC from the French Temps Universel Coordonné) is an international timescale based on the time told by atomic clocks. Atomic clocks are accurate to within a second in several million years. They are so accurate that International Atomic Time, the time relayed by these devices, is even more accurate than the spin of the Earth.

The Earth’s rotation is affected by the gravity of the moon and can therefore slow or speed up. For this reason, International Atomic Time (TAI from the French Temps Atomique International) has to have ‘Leap seconds’ added to keep it in line with the original timescale GMT (Greenwich meantime) also referred to as UT1, which is based on solar time.

This new timescale known as UTC is now used all over the world allowing computer networks and communications to be conducted at opposite sides of the globe.

UTC is governed not by an individual country or administration but a collaboration of atomic clocks all over the world which ensures political neutrality and also added accuracy.

UTC is transmitted in numerous ways across the globe and is utilised by computer networks, airlines and satellites to ensure accurate synchronisation no matter what the location on the Earth.

In the USA NIST (National Institute of Standards and Technology) broadcast UTC from their atomic clock in Fort Collins, Colorado. The National Physics Laboratories of the UK and Germany have similar systems in Europe.

The internet is also another source of UTC time. Over a thousand time servers across the web can be used to receive a UTC time source, although many are not precise enough for most networking needs.
