What Is Computer Hardware | Introduction | Components | Specifications



A computer system consists of hardware, software, and firmware. To build a computer, we must first gather the necessary hardware. Hardware is the part of the computer that you can touch and feel. When most people view a specific computer, they understand what physical components they are using, such as a rigid metal or plastic system unit, central processing unit (CPU), power supply, disk drive, and other essentials. Component. The hardware is limited by its manufacture date and specially installed motherboard. Depending on age and availability, some hardware items may be expensive to acquire, repair, or replace. For example, if the computer is running slowly over time with the addition of new software, it may be necessary to increase the amount of physical memory called RAM (random access memory) in the computer. To do this, the technician will need to purchase the correct size, speed and style of memory according to the motherboard specifications and install it into the computer which will then increase its ability to process information more quickly.


Computer hardware consists of mechanical and electrical parts of a computer. Data flows through the motherboard which is known as the system bus. External ports, which are discussed in more detail in this lesson, allow peripheral devices to be connected to a system unit. Common ports are USB, serial and parallel ports.

Peripheral devices contain hardware connected to the system unit and are designated as input, output, or both. Traditional input device examples are the mouse and keyboard used for input data.


Output devices include common items such as monitors, speakers, and printers. All these devices are ways that a computer user can respond through visual or auditory output.

Traditionally eccentric devices have become both input and output. Gaming joysticks that provide feedback to the user through vibration and of course touch-screen displays now function as both.



The CPU is the master of the computer. Each subsystem, including input, output, and storage systems, interacts with and through the processor. For example, the processor receives user input (such as double-clicking a mouse on the screen), then interacts with the storage device (such as a hard drive) to retrieve the file. Processing, which is the act of taking data that has been inputted and converting it into something usable. Then, the processor creates a visual display of the file by outputting it to the monitor through the output subsystem.

Some hardware performs storage. Storage functions are handled in the storage subsystem. This area focuses on the act of saving data for future use and retrieval. Early computers had very limited storage, so each program had to be entered before running it, every time you wanted to use it. In modern computers, storage space has increased rapidly; Even basic computers have hundreds of gigabytes or even terabytes of information storage. Computers use both short-term and long-term storage in their daily operations. For example, when you are typing a report for school, it is stored in the computer's short-term memory (RAM) while you are typing and editing the document. Once you save the document, it is transferred to a hard drive (internal) or a USB flash drive (external) for long term storage and future use.

Parts & Functions Of Computer | Input, Process, Storage & Output


  

What makes a computer a computer? Is it necessary to have a few pieces to consider a computer a computer? Consider computers of the 1980s: they all consisted of a display screen, a keyboard, and a processing unit. Over time, computers have evolved into devices that do not look like "typical" computers. Consider an iPhone or Android tablet, where the method of input depends on touch, without the use of a separate keyboard.




Regardless of the machine's form factor, four basic functions - input, output, storage, and processing - make up a computer. Below is a demonstration of how those tasks work together.


Therefore, as we consider the history of computers and the future of computers, we must consider what is a computer and what is not. Obviously, we have desktop and laptop computers, as they perform input, processing, output and storage functions. But also because we have cellular phones and smartphones because they perform all these functions. What about our television? Many of these are also complex computers, as they take information from our inputs using a remote control, process the information, and return the output, such as an on-demand movie. Many of these televisions store information, such as your favourite channels or even video content for later playback. Some thermostats are even computers, as they perform these functions, such as "smart thermostats", such as NEST and other popular brands. Remember, the main determinant of something is the computer or not it depends on what works: does it do input, processing, output and storage? If so, it is a computer.
