Computer Hardware:

• Central Processing Unit (CPU):

  • The CPU is the "brain" of the computer, responsible for executing instructions and performing calculations.

  • It determines the computer's processing speed and performance.

• Random Access Memory (RAM):

  • RAM is a type of volatile memory that stores data and instructions that the CPU needs while it's actively working on tasks.

  • It provides fast access to data but is temporary, as it's cleared when the computer is powered off.

  • More RAM generally allows for smoother multitasking and faster application performance.

• Hard Disk Drive (HDD) and Solid-State Drive (SSD):

  • The hard disk drive (HDD) and solid-state drive (SSD) are storage devices for your computer.

  • HDDs use spinning disks to store data, while SSDs use flash memory. SSDs are faster and more reliable but often cost more per gigabyte.

  • These devices store your operating system, software, files, and data.

• Motherboard:

  • The motherboard is the main circuit board that connects and controls all hardware components in your computer.

  • It has sockets for the CPU, RAM, and various expansion slots for peripherals.

• Graphics Processing Unit (GPU):

  • The GPU, also known as a graphics card, is responsible for rendering images and videos.

  • It is essential for gaming, video editing, and graphic-intensive tasks.

• Power Supply Unit (PSU):

  • The PSU provides electrical power to the computer's components.

  • It converts electricity from your wall outlet into the appropriate voltages and currents required by your hardware.

• Optical Drive:

  • Optical drives (e.g., DVD-ROM, Blu-ray) are used for reading and writing optical discs, such as CDs, DVDs, and Blu-ray discs.
