What does RAM stand for?
Comuter systems
Random Access Memory
What does ROM Stand for?
Comuter systems
Read Only Memory
What does RAM do?
Comuter systems
- It is the volatile memory.
- Temporary data
- Current running applications
- data and instruction are stored on the RAM
What does ROM do?
Comuter systems
- It is the read only memory
- Non-volatile
- Permanent data
- Boot strap locator (BIOS)
- Part of the operating system
What is stored on the RAM?
Comuter systems
Data and Instructions that are in current use.
What is stored on the ROM?
Comuter systems
The programming that allows the computer to start up or regenerate each time it is turned on.
What are the internal components of a computer system?
Comuter systems
- Motherboard
- CPU
- RAM
- Hard Drive
- Solid-State drive (SSD)
- Optical drive
- Heat sink
- Graphics processing unit
- Network Interface Card
What does the Motherboard do?
Comuter systems
- This is the printed circuit board that hold the central processing unit and other essential internal hardware and the function as the central hub that all the other hardware components run through
- Connects all the parts of the computer
Comuter systems
What does the CPU do?
Comuter systems
- It is the brain of the computer that processes and executed digital instructions from various programs , it’s clock speed determines the computer’s performance and efficiency in the processing data.
- Central Processing Unit
- Help fetch, decode and execute digital instruction form various programs
What does the RAM do?
Comuter systems
- It is the temporary memory storage that makes information immediately accessible to programs, RAM is volatile memory, so stored data is cleared when the computer is turned off.
What does the solid state drive (SSD) do?
Comuter systems
- They are solid-state storage devices based on NAND flash memory technology; SSDs are non-volatile, so they can safely store data even when the computer is powered down.
- It stores persistent data on solid-state flash memory.
What does the hard drive do?
Comuter systems
- They are physical storage devices that store both permanent and temporary data in different formats, including programs, OSes, device files, photos, etc.
- It stores everything that has been saved to this storage for the full computers history.
What does the Optical drive do?
Comuter systems
- Optical drives typically reside in an on-device drive bay; they enable the computer to read and interact with nonmagnetic external media, such as compact disc read-only memory or digital video discs.
- It allows you to use CDs, DVDs, and Blu-ray discs to listen to music or watch a movie.
What does the heat sink do?
Comuter systems
- This is a passive piece of hardware that draws heat away from components to regulate/reduce their temperature to help ensure they continue to function properly. Typically, a heat sink is installed directly atop the CPU, which produces the most heat among internal components.
- It removes heat form the devices components to improve device performance and extend its life.
What does the graphics processing unit do?
Comuter systems
- This chip-based device processes graphical data and often functions as an extension to the main CPU.
- It is responsible for calculating images in a computer, which can then be displayed on a monitor.
What does the network interface card (NIC) do?
Comuter systems
- A NIC is a circuit board or chip that enables the computer to connect to a network; also known as a network adapter or local area network adapter, it typically supports connection to an Ethernet network.
- It provides a computer with a dedicated, full time connection to a network.
