In workplaces, as well as in schools, shops, and public places in general, it is now hard to find a how is computer work on its own. These little great miracles of technology, dramatically improved over time, have been able to change the way of working, teaching, learning, and organizing in general, and they did it in just over twenty years!
This article provides an in-depth understanding of the construction and functionality, detailing the various components and their various functions within this large box. The operating system plays a crucial role in ensuring harmony and autonomy in computer operations, allowing users to perform tasks without being a genius.
Our journey inside the computer begins with studying what they are and what they serve all the pieces that are inside the box . In the lines below, I’ll explain what’s and what the processor , graphics card , RAM memory, and all the other components that make up these fascinating machines. You will see, at the end of this reading you will be perfectly able to distinguish them by eye and you will perfectly understand their usefulness.
Power Supply
The power supply is that component that gives electricity to all the other pieces of the computer. It connects directly to the power socket through the power cord and, out of it, several cables are connected to the components of the PC that require direct power—the motherboard, the disks , the optical readers and, in some cases the fans. There are mainly two types of power supplies: the modular ones , on which the cables are initially disconnected and can be added as needed, and the non-modular ones , on which the cables are installed from the beginning and cannot be disconnected. Let’s know about the best company for computer repair services.
Computer fan and cooling? Service
The power supply comes with a cooling fan – Power supplies, measured in watts, are crucial for computer configurations with multiple powerful components. High wattage supplies are essential for powerful graphics units and processors. If a power supply breaks, the computer will not light up.
The motherboard is the primary component of a computer, housing all other parts and coordinating the allocation of power supply current.
Numerous integrated circuits, connectors, expansion slots, and communication buses are located on the motherboard. These are use to connect the attach components to the connectors or expansion slots and to pass the data from one side to the other. The motherboard is directly mount on the case and securely fastest using screws.
Virtually everything that matters about the inside of the computer to operate and receive data needs to be connect to the motherboard: from USB ports to LEDs , through speakers , fans , disks , processors , RAM benches and everything the rest. That’s why I told you that the motherboard is the main part of the computer: if this breaks down, the computer will not work at all (since there would be problems in the passage of data) and it should be replace.
The motherboards are built with diamonds and copper, materials that help data transmission and at the same time resist high temperatures. There are several motherboard formats, which differ in size and number of mounted expansion slots . The ATX standard, available in Mini-ATX, MicroATX, and FlexATX versions, is the most popular choice for cases base on their desire size.
Processor
The processor is the heart of the computer: without it everything else would be completely useless! It is the internal component that manages to process the received data to provide it to all other parts of the computer, the operating system, and all its programs. Initially, processors were composed of various components for specific functions, but today, central data processing is integrated into a single printed circuit called a microprocessor.
The small microprocessor unit that deals with calculations is the CPU . In some cases, you can also find the graphics calculator unit (GPU) on the same CPU plate – in that case, this component is named APU . Initially, the processor could only perform one operation at a time (though extremely fast), but today there are more core processors – more processing units—that allow you to perform as many current tasks as possible.
Processors measure performance in GHz, but today’s high speeds require using GHz. Microprocessors have dedicated motherboard housing, cache memory, and can reach high temperatures, necessitating disassembly.
The major PC processor manufacturers are Intel and AMD , which offer processor families for various types of use. For example, Intel’s i series processors (eg i3, i5 and i7) are designed for the most powerful desktop computers and laptops, while core m processors (core m3, m5 and m7, and the latest generations have assumed the names of i5 and i7) are intended for ultrabooks and 2-in-1, which need reduced power consumption.
Video Card
The video card is that component of a computer that processes graphic data , that is all that can be seen on screen, thanks to the graphics processor (GPU) on it. The GPU receives data directly from the CPU and transmits them to the main video output device (usually the monitor).
But I have to make a point: not always the video card is present on a computer work, because the GPU can also be integrated into the motherboard or in the central microprocessor (in this case you talk about APU, I’ll explain it shortly). In some computers, you can find both the integrated GPU and an independent video card—or, in technical terms, a discrete video card . Some particularly powerful configurations can also provide multiple video cards together , perhaps linked together to increase performance.
The video card is a circuit board typically enclosed by a silicon structure. Some particularly powerful video cards also feature one or more fans to lower the temperature reached. The video card, which is located in the PCI or PCI-e slot on the motherboard, can have dedicated RAM added to it for faster data processing. Once installed in the computer, the video card allows access to the communication ports from the back of the case, for connecting the monitor or other video devices. Among these are:
- the VGA port (if present);
- the HDMI or micro-HDMI port;
- the DVI port .
The main video card manufacturers are Nvidia and AMD , which offer GPUs of various powers belonging to various market segments: the most advanced, high-end gaming and professional applications (eg 3D design) cost hundreds of euro.
Are you saying you want to buy a new video card but would you like some other information about it? Perfect: I recommend that you go first on Wikipedia for a closer look.
Audio Card
As the name itself implies, the sound card is the component of the computer work that allows you to listen to digital sounds. Just like the video card, you can find it either integrated in the motherboard or as a separate component. In the latter case, the sound card has the shape of a thin rectangle with circuits and capacitors.
The motherboard powers the sound card directly, installing it in a special housing on the motherboard. Once installed in the computer, the sound card allows access to its communication ports from the back of the case. Among them are.
- the jack for headphones / speakers ;
- the jack for the microphone ;
- a set of jack for 5.1 or 7.1 (if compatible);
- a digital output for advanced systems.
Most motherboards have built-in sound cards, but audio file enthusiasts may benefit from enhancing the quality of computer sounds.
Cooling Systems
I know it may sound strange, but work creates heat and inside a computer it would be easy to get even at temperatures that exceed 100 degrees … if there were no cooling systems . The most common cooling method you can find inside a computer is the fan .
There is usually one in each of the most inclined components to heat up – a processor fan, a fan for the power supply, and a fan for the video card. The units directly above have fans with heat sinks for cooling. However, it is not unusual to find homes that include one or more fans to improve indoor ventilation.
Another interesting system to keep down the inside temperature of your computer work is liquid cooling. The system of pumps, fans, and tubes in a computer functions as a cooling agent, preventing internal components from overheating.
The liquid never comes into direct contact with the components, but the heat transfer takes place by convection : on each component to be cooled to liquid there is a waterblock that has a function similar to that of the heatsink and runs through the refrigerant liquid the component itself. Some liquid cooling systems come equipped with very light tubes, which are very pleasant to see. Wait a second, would you like to get a better idea of liquid cooling?
RAM Memory
The RAM is the component of a computer that acts as a “via” between the hard disk and cache of the processor and has the duty to speed up data traffic, since the processor bus works at much higher speeds than the disk. RAM memory, a printed circuit with benches, resembles a long and thin rectangle, storing information. The peculiarity of RAM is that it is completely empty in the absence of electricity: it is a “transitory” memory that passes data that is eliminat when the computer work is shut down, the data of the applications in use and the running processes of the system.
RAM Memory Measures in GigaByte: The larger is, the more information it can contain, the more computer performance increases, especially in multi-taskingoptics (that is, running multiple programs at the same time). The special motherboard housings often have a “snap-in” mechanism to facilitate mounting and disassembly. The storage media directly communicates with the processor.
DIMMs and SO-DIMMs are popular RAM formats for desktop computers and laptops, respectively. Bus frequency, measured in MHz, allows for different communication speeds with the computer. Now that I’ve explain to you what is needed and where is RAM install. Did you want to buy a new bench to speed up your computer more? The speaker provides comprehensive advice and detailed explanations on the various features of memories.
Hard Disk (Hard Drive or SSD)
The hard disk is the part of a computer that stores persistent data, which must last in time. It is about it that you can find the operating system, installed programs and all the files and folders. The hard disk directly connects to RAM, transferring data from the operating system to RAM for processing by the processor.
There are mainly two types of fixed disks: the mechanical disk that uses handles and heads to save and retrieve data, and the solid state disk (or SSD ), which instead uses a set of small, power-charged memories. In addition, you can find hard disk drives from different storage cuts; the unit of measure to measure the available space is GigaByte (GB, equivalent to 1000 or 1024 MB, depending on the disc manufacturer’s estimates) or TeraByte (TB, which equals 1000 or 1024 GB), and more a hard drive is large more data can hold.
A hard drive can be either 3.5″ (classic mechanical disk) or 2.5″ (standard size for SSDs and portable mechanical disks). The hard disk is house in a specific housing and connect to the motherboard via a SATA data cable (I, II, or III).
The hard drive must directly receive electricity from the power supply, which connects via an SATA power cord.
Network Card
A network adapter is a device that allows connections to a network or the Internet. The device can connect via Ethernet or Wi-Fi. It has a thin rectangle shape with printed circuit boards and an antenna if wireless. It houses and feeds directly from the motherboard via the PCMCIA or PCMCIA -e input (which stands for express).
The network card, once installed in a computer, allows access to communication ports from the back of the case. Among these are:
one or more ethernet ports for connecting network cables;
one or more Wi-Fi antennas for wireless networking.
Homes
The case is the case where all the other components of the computer are located, the so-called ” box “. A case typically consists of sheet steel or aluminum to enhance thermal conductivity, allowing its components to withstand high temperatures.
Houses feature special housings, guides for cables, LED indicators, pushbuttons, communication ports, and fans, with some cases including pushbuttons and communication ports.
- Power button – is the key you use to turn the computer on and off. It is usually on the front or top edge.
- Reset button – is the key you use to restart your computer brutally , without turning it off “clean”.
- LED indicators – are the “lights” of your computer, the indicators that show you what’s going on inside. Usually, a power LED in a case illuminates when you turn on the computer. It is a dedicated disk LED that illuminates when the drive is in use. The LED indicators need to connect to the motherboard to function properly.
- Communication ports – Some homes already have communication ports on board, in comfortably accessible places – generally on the front. For example, you may find headphone and microphone jack, USB ports or eSATA ports. In order for the ports to work properly, you must connect them to the motherboard.
- Fans : Some houses use one or more fans as part of their cooling system. The fans must also connect to the motherboard or power supply.
The side panels of the case can easily be dismantle for assembly and cleaning, with a height ranging from 33-70 cm. Small houses require careful motherboard format selection.
