hardware
The hardware component of a computer all the physical and tangible parts that make up the entire system that makes possible the operation of data processing. Among the most important parts that make the hardware of a computer is the processor or microprocessor, formerly known as CPU (Central Processing Unit), which is the brain or heart of the system, through which pass all the data, motherboard , or motherboard, which contains all circuits that interconnect the components of the hardware.
The processor is embedded on the motherboard connected to an interface that acts as a link between this and all other system components, called chipset. This form key elements of the hardware. The characteristics of these elements depend on 80% of the system's speed and fast data processing.
Then also embedded on the motherboard, are the places for other elements also play important roles. Among them stands out the RAM, which serves to assist the processor in the administration of data processing, the size of it being critical to the processor is not saturated in their actions.
The RAM memory is used in a computer for temporary storage and work (not massive). The RAM temporarily stores information, data and programs that the processor reads, processes and run. RAM is known as the computer's main memory, unlike the so-called auxiliary memory and mass storage (like hard disks, magnetic tapes or other memories).
The reports have had a very important development and has generated in a very short period of technologies that increase the speed of them and their storage capacity. For a normal computer RAM memory capacity should not be inferred from 1 GB to operate the system smoothly.
Another hardware component that has been a great evolution for their importance to have increased the use of videos and images of excellent quality, leading to an important file size, are the graphics cards. Also known as video cards are a very important hardware to play continuously, without freezing the screen, the latest games placed on the market by the leading companies in this market
They now have their own memory and processing unit, this last call u nity GPU (or GPU, English acronym for G raphics Processing Unit). The basic objective is to make only GPU graphics processing, freeing the main processor (CPU) of this expensive task (in time) to enable and perform other functions more efficiently.
Prior to these video accelerator cards, the main processor was responsible for building the image while the video section (either card or motherboard) was simply a translator of the binary signals to the signals required by the monitor, and much of main memory (RAM) computer was also used for these purposes.
In addition to these important components, we have the hardware group known as input devices, which are the means to enter data that the processor is responsible for processing. Within this group is the keyboard, mouse or the mouse, scanner, microphone, webcam, reader barcode, Joystick, CD or DVD (only reading), etc..
Just as there is this group of input, which as we said the data into the system, exist within the hardware, output peripherals, ie those who are responsible for visualizing the results of the requested operation to the processor. Within this group are as central, monitors, printers and speakers or speakers.
