2. An Overview of the Hardware Components
CPU and RAM
The central processing unit (CPU) is the brain of a computer, responsible for processing all of the data the computer receives and executing commands. CPU speed is measured in GHz (gigahertz) and higher GHz means faster performance. Random access memory (RAM) is the short-term memory of a computer — it stores the data that the CPU is actively using for computations. The more RAM a computer has, the better it can process large amounts of data at once.
Computer storage is measured in bytes (e.g. gigabytes, terabytes). Solid-state drives (SSDs) are faster and more reliable than traditional hard disk drives (HDDs), which use spinning platters to store data. SSDs are more expensive per GB, but are less susceptible to damage from drops or impacts.
Graphics processing units (GPUs) are specialized processors designed to handle complex graphical operations. They’re essential for gaming and tasks like video editing. Some CPUs have integrated graphics, but dedicated GPUs are generally faster and more powerful. GPUs also use VRAM (video RAM) to store graphics data, which is separate from system RAM.
Motherboard and Power Supply
The motherboard is the main circuit board that all the hardware components connect to. It’s responsible for sending data between the CPU, RAM, and other components. The power supply unit (PSU) supplies electricity to the computer. PSUs are rated by wattage, and a higher wattage PSU is needed for more powerful components. It’s always a good idea to choose a PSU with a higher wattage than what’s needed to allow for future upgrades.

Ports, connectors and circuits, oh my! The motherboard is the powerhouse behind your computer’s performance. As the central hub of your entire system, it’s responsible for integrating all components together. This vital piece of hardware connects your CPU, RAM, GPU and all other parts to ensure they work in harmony.
A computer’s motherboard is often referred to as the printed circuit board, or PCB, because of the circuits that run across its surface. These circuits are the electrical pathways that allow data and information to flow around your computer. They can be thin and delicate, so it’s important to handle them with care when installing or removing hardware.
Aside from circuits, the motherboard also contains connectors for various components. You’ll find sockets for your RAM, PCIe slots for your graphics card, and SATA ports for storage devices. Motherboards usually have USB and Ethernet ports too. It’s important to check what kind of ports you need before choosing a motherboard. For example, if you’re using an M.2 SSD, make sure your motherboard supports this kind of storage.
One of the most important parts of a motherboard is the BIOS. The BIOS is a program stored on the motherboard that oversees the boot-up process. It checks that all components are present and accounted for, sets the system time, and initializes hardware settings. If the BIOS detects a problem during the boot process, it will notify you via a beep code or message on your screen.
In conclusion, the motherboard is the hub of your computer system. Its circuits, connectors, and BIOS combine to create a platform that allows all your components to communicate with each other. When choosing a motherboard, make sure it has the connectors and BIOS settings you need for your hardware. By doing this, you’ll build a system that runs efficiently and optimally.
4. The CPU: The Brain of the Computer
The CPU, or Central Processing Unit, is the main component of a computer’s hardware. It is often referred to as the brain of the computer because it is responsible for managing all the computer’s operations. The CPU’s presence is essential to the functioning of a computer because it controls how data is processed and transformed into instructions.
The CPU’s primary function is to perform calculations and other logical operations. It does this by following a set of instructions, referred to as code, stored in the computer’s memory. The CPU retrieves these instructions, interprets them, and then executes the necessary operation. It performs these operations incredibly quickly, which enables computers to perform millions of calculations in just a few seconds.
The speed at which a CPU can perform these calculations is measured in Hertz (Hz) or Gigahertz (GHz). A higher number of Hertz or Gigahertz means that the CPU can perform calculations faster. The optimal speed of a CPU depends on its intended use. CPUs used in gaming computers, for example, require a higher speed than a CPU used in a computer that’s primarily used for word processing.
The CPU is the central computing component in a computer, but it works in conjunction with other hardware components such as the motherboard, RAM, and hard drive to enable the functioning of the computer. The CPU’s efficiency depends on the performance of all the hardware components working together. If one component is limiting, it can impact the CPU’s overall performance.
Overall, the CPU is the brain of the computer that is responsible for managing all the computer’s operations. Its significant role in a computer’s functioning makes it one of the most important hardware components in a computer. As such, it’s essential to consider the CPU’s intended use and its intended operating speed when choosing a computer or upgrading the CPU in an existing computer.
5. RAM: The Computer’s Short-Term Memory
RAM stands for Random Access Memory and is a crucial component of a computer’s overall architecture. It is sometimes referred to as the computer’s short-term memory because it temporarily stores data that the computer needs to access quickly. RAM is different from the computer’s hard drive, which is used for long term storage. Without RAM, a computer would not be able to operate efficiently.
RAM is a type of volatile memory, meaning that it requires a constant electrical charge to maintain data. This makes it different from non-volatile memory, such as a hard drive or flash drive, which can hold data even when the power is turned off. Because RAM relies on a constant electrical charge, it cannot be used for long term storage.
The amount of RAM in a computer is an important factor in its overall performance. If a computer has too little RAM, it may run slowly or freeze up when trying to handle large tasks. On the other hand, having too much RAM can be wasteful and not improve performance beyond a certain point.
One benefit of having more RAM is that it allows a computer to run more programs simultaneously. This is useful for users who frequently multitask or run programs that require a lot of memory, such as video editing software or video games. Additionally, having more RAM can also reduce load times, allowing for faster access to frequently used programs and files. Overall, RAM is an essential component of any computer and its performance can greatly impact the user’s experience.
6. The Hard Drive: The Computer’s Long-Term Memory
The hard drive is like the brain of your computer – it is the place where it stores all the information that it needs to function. It is called the long-term memory because it holds all of the data and programs that you save on your computer, even when you turn it off.
Hard drives come in different sizes and speeds, with larger drives and faster speeds being more expensive. The size of a hard drive is measured in gigabytes (GB) or terabytes (TB), and it determines how much space you have available to store your files. A larger drive will be able to store more files, but it may also be slower, especially if it is an older model.
The speed of a hard drive is important because it determines how quickly your computer can access and save files. A faster drive will make your computer run more smoothly and quickly, especially if you are working with large files like videos or images. There are two types of hard drives: solid-state drives (SSD) and traditional hard disk drives (HDD). SSDs are much faster than HDDs because they use flash memory to store data, while HDDs use spinning disks.
When you save a file on your computer, it is stored on the hard drive. The computer can retrieve that file later when you need it. However, if the hard drive fails or becomes damaged, you may lose all the data stored on it. That is why it is important to back up your important files on an external hard drive or in cloud storage.
In summary, the hard drive is the computer’s long-term memory, storing all the data and programs on your computer. It comes in different sizes and speeds, with larger and faster drives being more expensive. The speed of the hard drive is important to how quickly your computer can access and save files.
