Classification of computers :computer:
Super computers
These are arguably the most
powerful in terms of speed and accuracy.
Can go even
faster with the rate of petaFLOPS (or PFLOPS).
The typical personal computer used at home and the office is only capable of calculating millions of instructions per second (MIPS).
Types of computers used in solving complex mathematical computations
PERSONAL COMPUTERS
Microcomputers or Personal computers
The smallest, least
expensive, and the most used types of
computers.
Physically
smaller
Less processing
power
permit fewer peripherals compared to super and mainframe computers.
Small memory,
commonly call personal computers or PCs.
The term was
initially used to refer to IBM compatible computers.
EMBEDDED SYSTEMS
These are computer- based systems which are standalone electronic hardware designed to perform dedicated computing tasks.
They are just like computers but not like the other types of computers.
Popular
devices that may be categorized under embedded systems
Etc.
MP3 players
Printers
DVD players
Set-top boxes
Telephones
Drones
video game consoles
ATM machines
MID-RANGE COMPUTERS
Encompass a very broad range and reside in capacity between high-end PC servers and mainframes.
Also known as mini-computers
Popular in the late 1960s but have become
almost extinct because of the popularity of
personal computers.
Mainframe computers
High-performance computers with large amounts of memory and processors that process billions of simple calculations and transactions in real time.
Called a mainframe or big iron
This makes them
popular with businesses.
SERVERS
Types of computers used to
functionality to client computers in a server-client network model.
Resources
Services
Resources provided
are based on the functions of a particular server
which may fall under these
