Parts of Computers
RAM
What it is:
RAM, also known as volatile memory, stores data regarding frequently accessed programs and processes
-
-
GPU
What it is?
It's not uncommon to hear gamers obsess over the next new graphics card, as these graphic cards make it possible for computers to generate high-end visuals like those found in the many different types of video games.
-
What it does?
Graphics cards often communicate directly with the display monitor, meaning a $1,000 graphics card won't be of much use if there isn't a high-end monitor connected to it.
-
Motherboard
What it is?
All components of a computer communicate through a circuit board called the motherboard, as was mentioned above.
-
-
CPU
What it is?
The CPU is often called the "brain" of a computer, thanks to its direct plug connection to the motherboard, and communication with all of the computer’s other components.
-
What it does?
Whenever you write a line of code (in Python, Java, C++, or any other programming language), it's broken down into assembly language—which is a language that the processor can understand. It fetches, decodes, and executes these instructions.
-
Storage
What it is:
All computers need somewhere to store their data. Modern computers either use a Hard Disk Drive (HDD) or Solid State Drive (SSD).
-
What it does
HDDs are made of an actual disk onto which data is stored. The disk is read by a mechanical arm. (HDDs are cheaper than SSDs, but are slowly becoming more and more obsolete.)
-
Types of Computers
Supercomputers
The most powerful gadgets in the world are actually sets of different computers integrated into a single unit, which can be powered up exponentially.
-
Mainframes.
They are also known as mainframes, and are usually large (at least compared to laptops) and found in carefully cooled rooms within large companies or institutions in a country.
-
Laptops
Although it is in fact personal computers, we list this type of device separately because it is physically light parts, designed for use outdoors or to travel with us in a briefcase.
