Hardware basics 1

A few days ago, I have started new course. It is computer and internet. This course is very interesting and very useful, because it is all about computer. Computer is a machine that we have been using for several ages. So in this week’s post, I am going to show you what I have studied along with challenging points.

In this week’s lesson, we started with new first topic. It is hardware basics which included conceptions and number systems of computer.

As we know that computer is a programmable machine that processes the data into the information. Basically, computer consists of two big components which are hardware and software.

- Hardware is the electrical or mechanical parts of computer known as physical parts.

- Software is a series of related instructions that tell computer what task to perform known as program. It consists of system software and application software.

- If we have a set of computer, we can see that there will be five elements involve in information processing cycle or known as computer operation. They are input, processing, output, storage and communication.

As I have mentioned, there is a challenging part which is number system. Actually, I really do not know what number system is all about. Eventually, I know what it is. There are five number systems. They are decimal system that has a base of ten or X₁₀, binary system that holds on a base of two or X₂, octal system that has a radix of eight or X₈, and hexadecimal system that has a base of sixteen or X₁₆. The cryptic point is we were given chance to convert a number system from one to another. There was confusion in my mind. Nevertheless, I could overcome my confusion by giving a full attention on the lecture.

However, computer has become as a part of human nowadays. Why it is so, because it efficiently helps people in daily tasks with its strengths included its speed, reliability, consistency, storage and communication. What is more, people’s life has even become more comfortable and convenient.
