The answer is the second one: sends information to other computers on a specific network.
Explanation for each option:
The part of the computer that stores information: This description is more accurate for a storage device or a hard drive, not a server. A server may store information, but its primary function is not just storage.
Sends information to other computers on a specific network: This is the correct definition of a server. A server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network.
Is an internet provider: This is incorrect. An internet provider, or Internet Service Provider (ISP), is a company that provides individuals and organizations access to the internet. A server is not an ISP.
In summary, a server is a system that sends information to other computers on a specific network.
