IntroductionThe word “computer” these days is very famous among all of us. Almost every one of us had our own personal computer. In fact, a portable personal computer or also known as a laptop was introduced to the world by Adam Osborne in 1981. Most people prefer to use a laptop because it is very easy to carry wherever you go. As the laptop becomes famous over the years, they try to make it as convenient as possible. For example, the laptop of the past was quite heavy and bulky. Since then, they've made it even thinner, lighter and even smaller. I myself started using the computer since the age of 10 and I see a very big transformation in terms of creation and technology. What is a computer? In general, a computer is a programmable machine. The main characteristics of a computer are that it responds to a specific set of instructions in a well-defined way and that it executes a prerecorded list of programs. It also has the ability to store, retrieve and process data. We can use a computer to enter documents, send emails, and browse the Internet. We can also use a computer to handle tasks such as database management, presentations, accounting, spreadsheets, games, etc. What is computer hardware? Hardware refers to all the physical parts of a computer. Things you can actually see and touch. Computer Hardware Basics A computer system consists of inputs, outputs, processing, and storage. One of the basic computer hardware is the motherboard. It was previously called a motherboard. It is the main component of a computer. The motherboard is used to connect all the parts of a computer together. It can also be called the “backbone” of a computer because it is the hardware that ensures the computer functions properly. System board...... middle of paper ...... and tutorials over the last few weeks I have learned a lot about computer hardware. Before this, I have so little information about what computer hardware is. When my friends ask me about computer hardware, I usually tell them that it's something you can see with your own eyesight, but it's not just about our visual. It also implies something that can be touched. Computer hardware is very important because without it, the computer itself will not function properly. Actually, I have an experience where I don't know how to refill inkjet printer ink. I'm very lucky because the printer existed during my primary year. The evolution of the printer in terms of technology has accelerated. The same goes for the keyboard. Nowadays, these are also touchscreen keyboards. I'm really fascinated by the growth of this hardware.
