A computer is a machine that accepts information (data) as input and then processes and outputs the data based on a set of instructions. The 7 major components of a computer are:
A motherboard is the main circuit board in a computer. It holds many of the key components of a computer and provides a means for them to interact with one another. The motherboard includes the central processing unit (CPU), random access memory (RAM), graphics card, northbridge, southbridge, and other essential components.
The motherboard is also responsible for providing power to the other components and allows for communication between them. It connects to the power supply unit (PSU) via a power connector and to the case or chassis via a number of screws or bolts.
What are the different types of motherboards?
There are three main types of motherboards: ATX, microATX, and mini-ITX.
ATX motherboards are the most common and are usually used in desktop computers. They measure 305mm by 244mm and have a number of different connectors, including a 24-pin power connector, four SATA connectors, an 8-pin CPU power connector, and a 6-pin PCIe power connector.
microATX motherboards are slightly smaller than ATX motherboards and are often used in small form factor (SFF) PCs. They measure 244mm by 244mm and have a number of different connectors, including a 24-pin power connector, two SATA connectors, an 8-pin CPU power connector, and a 4-pin PCIe power connector.
mini-ITX motherboards are the smallest type of motherboard and are often used in embedded systems. They measure 170mm by 170mm and have a number of different connectors, including a 20-pin power connector, one SATA connector, an 8-pin CPU power connector, and no PCIe connectors.
Power Supply Unit (PSU)
A power supply unit (PSU) is an electronic device that converts AC to DC power. It provides power to the motherboard, storage devices, and other components in a computer system.
There are two types of PSUs: ATX and mini-ITX.
ATX PSUs are the most common type and measure 150mm by 86mm. They have a number of different connectors, including a 24-pin power connector, four SATA connectors, and two PCIe power connectors. mini-ITX PSUs are slightly smaller than ATX motherboards and are often used in small form factor (SFF) PCs. They measure 244mm by 244mm and have a number of different connectors including a 24-pin power connector, four SATA connectors, and one PCIe power connector.
When choosing a PSU, you should consider the wattage rating and the number of connectors. The wattage rating is the maximum amount of power that the PSU can deliver. The number of connectors is important because it determines how many components you can power with the PSU. Most PSUs have a wattage rating of 500-600 watts, but there are a few high-end models that offer ratings up to 1,200 watts.
When buying a PSU, it’s important to make sure that it’s compatible with your motherboard and other components. The most common form factor is ATX, so make sure that the PSU you buy has an ATX form factor. You should also check the connector type. The most common connector types are the 24-pin connector and the 4+4-pin connector.
A computer processor, also known as a CPU, is the main component in a computer. It performs all of the calculations and logical operations that allow your computer to function. CPUs are made up of millions of transistors and are typically packaged in a square or rectangular chip.
There are two main types of processors: Intel processors and AMD processors. AMD processors tend to be less expensive than Intel processors, but Intel processors tend to be faster. In recent years, however, AMD has begun to close the performance gap between its processors and Intel’s processors.
When choosing a processor, you’ll need to decide how much money you want to spend and how fast you want your computer to be. If you’re looking for a budget-friendly option, AMD processors are a good choice. If you’re looking for the best performance possible, Intel processors are the way to go.
Random Access Memory (RAM)
RAM (Random Access Memory) is one of the most important components inside a computer. It’s a type of processor that helps your computer to run quickly and easily by providing a space for programs and data to function. When it comes to RAM, more is always better. If you’re running low on memory, your computer will start to slow down and you might even experience crashes. To keep your computer running at best, be sure to upgrade your RAM when necessary.
Computer RAM is usually measured in GBs, but it’s important to remember that more GBs does not mean better memory. This is because your computer’s operating system utilizes a portion of the RAM as well which reduces how much space you have for programs and files. Like most things, the best way to determine how much RAM you need depends entirely on what you use your computer for and how often you use it. If you’re someone who likes to play games or work with large video and audio files, we recommend upgrading your RAM as soon as possible. For those who simply browse the web or check email, 256GB should be enough to keep your machine running smoothly even years from now!
