Computer Hardware: An Overview Computer hardware is the physical components that make up a computer. It includes the CPU, RAM, storage devices, motherboard, and more. DG by Dilara Guluzadeh
CPU (Central Processing Unit) 1 The Brain The CPU is the brain of the computer, responsible for processing information. 2 Processing Power It handles instructions, calculations, and tasks, impacting system speed. 3 Multi-Core Modern CPUs have multiple cores to handle multiple tasks concurrently. 4 Clock Speed Clock speed measures how fast the CPU processes instructions.
RAM (Random Access Memory) Short-Term Memory RAM acts as short-term memory, holding data that the CPU needs to access quickly. Speed and Capacity RAM speed and capacity affect how quickly a computer can load and run programs. Volatile Memory RAM is volatile, meaning data is lost when the computer is turned off.
Storage Devices Hard Disk Drive (HDD) HDDs are older, using spinning platters to store data. They are cheaper, but slower. Solid State Drive (SSD) SSDs are newer, using flash memory to store data. They are faster, but more expensive. Other Storage Other options include USB drives, external hard drives, and cloud storage.
Motherboard 1 Connects Components The motherboard is the main circuit board that connects all the other components. 2 Expansion Slots It has slots for expansion cards, such as graphics cards, sound cards, and network cards. 3 Chipset The chipset controls communication between the CPU, RAM, and other components.
Power Supply Unit (PSU) Provides Power The PSU converts household AC power into DC power that the computer can use. Wattage The wattage rating of the PSU determines how much power it can provide to the system. Efficiency PSU efficiency impacts energy consumption and heat generation.
Graphics Processing Unit (GPU) Function Dedicated to Graphics Processing Handles complex visual tasks Benefits Improved gaming performance, smoother video editing, and better visual quality
Input Devices Keyboard Allows users to enter text, commands, and data into the computer. Mouse Used for navigation, selecting items, and controlling the cursor on the screen. Microphone Captures audio input for voice commands, recordings, and communication. Scanner Converts physical documents into digital images.
Computer Hardware Computer hardware refers to the physical components of a computer system. These components work together to perform tasks, process information, and provide users with an interactive experience.
Output Devices Monitor Displays visual output, such as text, images, and videos. Printer Produces hard copies of digital documents and images.
Cooling Systems 1 Heat Management Cooling systems prevent overheating, which can damage components. 2 Fans and Heat Sinks Fans circulate air, while heat sinks dissipate heat from components. 3 Liquid Cooling Liquid cooling systems are more efficient and can keep components cooler.
