All of the components in a computer communicate via the motherboard, which functions as a kind of digital glue. It relays instructions to the other pieces of hardware.
RAM temporarily holds data the CPU needs to perform tasks, enabling faster program execution. Storage devices like hard disk drives (HDDs) or solid state drives (SSDs) permanently store applications and files.
Motherboard
The motherboard is the main printed circuit board that connects all major computer components and carries essential chips, slots, sockets, and ports that determine the performance, expandability, and compatibility of your system. It also houses the central processor (CPU) and provides expansion slots for adding add-in cards like a graphics card or network controller.
Other features include a BIOS chip that runs your computer before the OS starts and a CMOS battery for low-level system control. Most motherboards also feature ports for connecting storage devices like HDDs and SSDs.
Processor
The processor, or central processing unit (CPU), is the brain behind every component of your computer. It tells everything from disk drives to screens what to do.
CPUs perform arithmetic and logical operations like addition, subtraction, multiplication, and division. They also handle boolean and bitwise operations. They include a control unit and a set of registers, including general-purpose and floating-point. They include L1 and L2 cache memory.
RAM
RAM provides the fast access and storage that keeps your computer running smoothly. It increases the speed at which programs run, allowing you to multitask and work quickly.
Unlike hard drives or SSD’s that keep data for long periods, your memory processes information much faster. This is why older computers take longer to boot and load software. This loss of productivity can cost your company money.
Hard Drive
A hard disk drive (HDD) is a non-volatile data storage device. It consists of one or more stacked disk platters housed in an air-sealed case. Data is written to the platters using a magnetic head that rapidly moves over them as they spin.
Modern hard drives use digital data interfaces and connect to a computer via ATA, SATA, SAS or USB cables. Frequent cleanups help create more space and improve performance.
Graphics Card
Graphics cards are responsible for creating the visuals that you see on your computer’s monitor. They can range from simple 2D graphics to advanced 3D games.
Integrated cards are built into the motherboard and cannot be upgraded or replaced. These are often used in laptops and inexpensive desktop PCs.
High-end graphics cards can process thousands of triangles or vertices per second, which makes them suitable for 3-D gaming and graphically intensive applications.
Sound Card
A sound card is an essential component for a computer, providing audio output to speakers or headphones. They have specialized chips and functionality that improves the quality of your music, gaming, home theater system or content creation.
A digital music file is sent from a program to the sound card, which converts it into an analog signal for the speakers. Sound cards can also provide microphone input and MIDI capability.
Video Card
Also known as a graphics card, it is the hardware component that renders visual information on screen. Its specialized processor speeds up the processing of graphics and images.
It can be integrated into the motherboard (called Integrated GPU) or as an expansion board that slips into a slot on the motherboard. Discrete GPU is upgradeable and can be replaced as newer ones become available.
Wireless Card
A wireless network card, also known as a Wi-Fi adapter, allows a computer or laptop to connect to the internet wirelessly. It can be integrated into general-purpose laptops or an external USB device.
The latest models feature multiple security protocols to prevent data hacking. Pair it with a strong graphics card to get the best performance when gaming or editing video.
Keyboard & Mouse
Keyboards and mice are essential computer peripherals that allow you to navigate a desktop or laptop computer. Choosing the right combo to meet your specific computing needs can improve productivity and enhance your user experience.
Wholesale keyboards from Meetion include ergonomic designs that promote comfortable usage and reduce the risk of repetitive strain injuries. Their mouses feature advanced optical sensors for smooth and precise tracking, maximizing accuracy during cursor movements.
Power Supply
The Power Supply converts AC electricity into DC power that the motherboard, hard drives and other system components use. It also supplies power to any installed peripherals, such as extra hard drives or graphics cards.
Most modern PSUs don’t directly plug into the motherboard. This simplifies and reduces internal wiring that can affect airflow and cooling, and also saves costs and energy.
