CCC Computer Basics

Computer hardware refers to the physical components of a computer system. These parts convert data from a digital format that the processor can read into a formatted output that the user can understand and interact with. There are several essential components of computer hardware, including the central processing unit (CPU), memory, storage, input devices, output devices, and peripherals.

Central Processing Unit (CPU)

The CPU is considered the brain of the computer. It's responsible for executing most of the calculations and logical operations needed to perform tasks on your computer. The speed of the CPU's operation determines how quickly these operations can be performed, which affects the overall performance of your system.

Processor Architecture

Processor architecture refers to the design decisions made by engineers when creating a CPU's microarchitecture. These decisions impact the efficiency and speed of the processor. Some common architectures include x86, ARM, 6502, and Zilog Z80.

Memory

Memory stores information temporarily while programs are running. While this information is stored, the program can access and manipulate it as necessary. This allows the program to do things without having all the information it needs right now, but just knowing where to find it.

Random Access Memory (RAM)

RAM is the primary memory used by your operating system and your applications. It serves as a workspace; as you work with files or use software, RAM provides the temporary space required for such activities.

Read-Only Memory (ROM)

Read-only memory (ROM) contains instructions that are always present in a computer. They cannot be modified under any circumstances. Examples of ROM are BIOS and boot sectors.

Cache Memory

Cache memory is a faster type of memory located between the CPU and main memory. Its purpose is to store frequently accessed information so that it can be retrieved more quickly than if it were obtained from RAM each time.

Storage

Storage holds important documents, music, videos, photos, and other files on your computer. Two types of storage media commonly found in computers are hard drives and solid state drives (SSDs).

Hard Drive

Hard drives are mechanical devices that store information magnetically. Data is written to the drive using magnetic force and is read using sensors that detect these changes in magnetism.

Solid State Drive (SSD)

Solid state drives have no moving parts. Instead, they store information on silicon chips. This makes them faster and more reliable than hard drives, although they are more expensive per unit of storage capacity.

Input Devices

Input devices allow users to interact with computers. Some common input devices include keyboards, mice, touchscreen displays, scanners, microphones, cameras, joysticks, gamepads, and controllers.

Keyboard

Keyboards enable users to input text and other commands through physical buttons or keys. They come in different layouts, depending on the language used.

Output Devices

Output devices help convey information to users through visual or auditory means. Some common output devices include monitors, speakers, printers, projectors, and televisions.

Monitor

Monitors display visual information processed by computers. They come in various sizes and resolutions, influencing the quality of images shown.

Speakers

Speakers convert digital audio signals into sound waves that humans can hear. There are numerous types, including desktop speakers, bookshelf speakers, tower speakers, and soundbars.

Peripherals

Peripherals expand the functionality of a computer beyond its basic capabilities. Some common peripherals include printers, scanners, digital cameras, smartphones, laptops, and smart home devices.

Printer

Printers produce paper copies of documents and images from digital data stored on computers. They come in various types, such as inkjet printers, laser printers, and thermal printers.
