✥ Operators: Operators are tokens that perform a particular operation on the given values, called operands.
✥ ORDER By Clause: ORDER BY clause sorts data on one or more columns in ascending or descending order.
✥ Output Devices: The output devices receive data from a computer and deliver the desired output on a suitable device for a
user.
✥ Platform as a Service (PaaS): PaaS provides users with a platform for building, deploying, and managing applications without
having to worry about the underlying infrastructure.
✥ Primary Key: One of the candidate keys is designated as primary key.
✥ Private cloud: A private cloud is a cloud infrastructure that is owned and operated by a single organisation and made available
to internal users over a private network.
✥ Program: Sequence of instructions given to a computer is called a program.
✥ Public cloud: A public cloud is a cloud infrastructure that is owned and operated by a third-party cloud service provider and
made available to the public over the Internet.
✥ Python Shell: Interactive Python interpreter is also known as the Python Shell.
✥ Random Access Memory (RAM): RAM is a random access memory in which data can be read from and written onto any
random memory location. It is also commonly known as main memory or read/write memory.
✥ Raw Facts: Data are raw facts.
