Storage is a space where you can save the data.

In computers,  storage is divided into two types.

1.Volatile memory -> Volatile memory is a temporary memory in which data is stored for a temporary period of time.

It is also known as a primary memory.

Examples are:- RAM(Random access memory)

2.Non-Volatile memory->Non-volatile memory is a permanent form of storage where data is stored permanently.

It is also known as a secondary memory.

Examples are:- Harddisk or any sort of removable devices are the non-volatile form of memory.

Main characterstic or features of comouter are speed accuracy diligence versatility and storage capacity which are taken in to consideration while communicating bet two points devices or persons

In a computer system memory is used to store data. the data stored inside memory in binary , i.e., in 0 and 1 only. that's why the capacity of memory is alwayes expressed in terms of bytes, like KB, MB , GB or TB

it is divided into two categories: Volatle and Non Volatile 

Volatile memory: Volatile means temporary or non stable. volatile memory stores data temporarily. when the compuer is switched off or there is power lost, all the data sored inside it lost immediately. RAM is the best example of this category.

Non Volatile: Non Volatile means permanent  or stable. non volatile memory stores data permanently, means even if the compuer is switched off or there is power lost, all the data sored inside it available, it will not lost. ROM is the best example of this category.

The external memory is a part of computer system but it is not permanent part. external memry like pen drive works with the computer but our computer can even work without these external memories

A software is the set of programs and program is the set of instructions.

a computer system composed of two part software and hardware.

hardware is the physucal part that is touchable.

software is the logical part and it is not touchable.

there can be two typres of softwares:

Sysyem softwares- these are used for system applications. without these softwares your system will not work properly. Compiler, interpreter, linker, loader are some examples of this category.

Application Softwares- these are used for some specific applications. if a particular application software is not present then you will not be able to open that particula type of application but it will not affect your system. some examples are: 

MS word, MS power point etc

ISP stands for Internet Service Provider. Internet service providers are responsible to provide internet service. so that, a particular person, company, institution can use internet services.

Some popular ISPs in India are:

Reliance Jio

Bharti Airtel

BSNL

Vodafone

You can go for courses like BCA or MCA where you can learn more about computer applications. There are courses on computer hardwares, data recovery etc.

Both reside on the Motherboard, ROM stores the Bios data and is known as permanant memory.

where as RAM stores the temporary data , the data act like cache. What ever you see on the Screen is stored on the RAM and will be wiped off once you switched off (Dont get confused with Physical storage drives)

Mostly you can use ctrl + z which is  undo command. 

Hibernate ORM (Hibernate in short) is an object-relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate handles object-relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions.
