Study Notes
Central Processing Unit (CPU)
- The CPU is the brain of a computer, responsible for executing instructions.
- It fetches instructions from memory, decodes them, and performs the necessary operations.
- Different types of CPUs exist, varying in speed and processing power.
- Modern CPUs are highly complex integrated circuits capable of executing billions of instructions per second.
- Clock speed, measured in Hertz (Hz), impacts the CPU's processing capability. Higher clock speeds typically indicate faster processing.
- Multiple cores are becoming increasingly common in modern CPUs, enabling parallel processing and significant performance improvements.
Random Access Memory (RAM)
- RAM is a volatile memory that stores data and instructions currently being used by the CPU.
- It provides fast access for the CPU to retrieve and store data compared to other storage devices.
- RAM is critical for a computer's overall performance, as the more RAM a computer has, the more programs and data it can hold in active use.
- Data in RAM is lost when the computer is powered off.
- Different types of RAM exist, with variations in speed and capacity. DDR4, DDR5 are common examples.
Hard Disk Drive (HDD)
- HDDs are non-volatile storage devices that store large amounts of data permanently.
- Data is stored on spinning platters with magnetic heads that read and write data.
- HDDs are generally less expensive per gigabyte of storage than other storage options like SSDs.
- HDDs are slower than SSDs due to the mechanical nature of the storage mechanism.
Solid State Drive (SSD)
- SSDs are non-volatile storage devices that use flash memory to store data.
- They have no moving parts, making them faster and more reliable than HDDs.
- Data access speeds are dramatically faster, resulting in noticeably quicker boot times, application loading, and overall performance.
- SSDs are more expensive than HDDs per gigabyte of storage.
Graphics Processing Unit (GPU)
- GPUs are specialized processors designed for handling graphical tasks.
- They accelerate the rendering of images, videos, and other visual content.
- GPUs are essential for tasks like gaming, video editing, and 3D modeling.
- Modern GPUs often include more processing cores than CPUs, optimized for parallel processing.
Motherboard
- The motherboard is the main circuit board of a computer.
- It connects all other components together.
- It provides power, communication channels, and slots for expansion cards.
- Critical for ensuring all computer parts operate correctly and interoperate together.
- Enables communication between different components like CPU, RAM, storage devices, and expansion cards.
Input Devices
- Input devices allow users to provide input to the computer.
- Examples include keyboards, mice, touchscreens, and webcams.
- They translate external data (e.g., typed text) into signals understood by the computer.
Output Devices
- Output devices display information processed by the computer.
- Examples include monitors, printers, speakers, and projectors.
- They present the results of computer processing in a user-friendly format.
Peripheral Devices
- Peripheral devices are any external device connected to the computer.
- They include all input and output devices.
- Printers, scanners, and external hard drives are examples of peripherals.
Network Interface Card (NIC)
- NICs are hardware components that enable a computer to connect to a network.
- They provide the physical connection between the computer and the network.
- Different types cater to network technologies (e.g., Ethernet, Wi-Fi).
Expansion Cards
- Expansion cards enhance the functionalities of a computer by adding specific capabilities.
- Examples include sound cards, video cards, and network interface cards.
- They plug into slots on the motherboard to extend computer functionality.
