Personal computer (PC): A general-purpose computer designed for individual use. It typically includes keyboard, mouse, monitor, and tower (CPU) or laptop. PCs are commonly used for Internet browsing, word processing, gaming, and multimedia types of purposes.
Laptop: As the name suggests Lap which means your legs Thai, and Top means the above. Compact and lightweight portable PC, designed to be used on the go. Laptops have a built-in keyboard, touchpad and display.
Workstation: A high-performance computer designed for complex tasks such as 3D modeling, video editing, and scientific simulations. Workstations typically have powerful processors, large amounts of RAM, and high level graphic cards.
Server: A computer that provides resources and services to other computers on the network. For example, this is our website and all files are stored in its server. The servers are designed to be reliable, scalable, and able to handle heavy workloads.
Mainframe: A large, powerful computer used by organizations or companies to process critical/complex resources and data. Mainframes are known for their high availability, security, and ability to handle large amounts of data.
Supercomputer: The most powerful type of computer, used for highly complex computations and simulations. Supercomputers are typically used in scientific research, weather forecasting, and other computationally intensive tasks.
Supercomputers
Supercomputers are the most powerful computers available, capable of performing trillions of calculations per second. They are used for tasks such as weather forecast, nuclear simulations, and scientific research and many more uses.
Supercomputers are typically built using a large number of processors or cores that work together in parallel to solve complex problems.
The design of supercomputers has evolved over time, with modern supercomputers utilizing large arrays of commodity processors operating in parallel over a high-speed communications network.
Internet and Networking
The internet is a global network of interconnected computers that allows for the exchange of information and communication.
Networking refers to the process of connecting computers and other devices to share resources and communicate with each other.
Network technologies include Ethernet, Wi-Fi, and cellular networks.
Internet connectivity and communication are necessary to access online services, surf the web, send emails, and communicate with others.
Personal Computer Hardware
Personal computer hardware refers to the physical components of a computer, including the central processing unit (CPU), memory (RAM), storage devices (hard drives, solid-state drives), graphics cards, and input/output devices (keyboard, mouse, monitor).
The hardware components of a personal computer work together to execute instructions, store and retrieve data, and provide a user interface for interacting with the computer.
The performance and capabilities of a personal computer are influenced by its hardware specifications, such as the speed and number of CPU cores, amount of RAM, and storage capacity.
Hardware Upgrade
A hardware upgrade involves adding new or additional hardware to a computer to improve its performance, increase its capacity, or add new features.
Common hardware upgrades include replacing the hard drive with a faster one or a solid-state drive (SSD) for improved performance, adding more RAM to increase the computer’s memory capacity, upgrading the graphics processing unit (GPU) for better graphics performance, or adding a USB 3.0 expansion card for faster data transfer.
Hardware upgrades can be necessary for older computers to meet the system requirements of new or updated software.
When performing a hardware upgrade, it is important to ensure that the compatibility between the new hardware and the older components. Tools like PCPartPicker can help identify and shop for compatible components.
