SSMS is only a client application. The install does not install the database engine or SQL Server Agent.
For development and testing, install Developer edition, which includes SQL Server agent. SQL Server Agent is not included with the Express Edition of SQL Server.
Hi @Samir Abbasfard ,
The agent is not visible if you use SQL Server Express. So I guess you are using the Express edition.
See this link:https://learn.microsoft.com/en-us/sql/sql-server/editions-and-components-of-sql-server-version-15?view=sql-server-ver15#SSMS
Here is a document about Upgrade to a Different Edition of SQL Server.
If I misunderstood what you mean please let me know.
Best regards,

my main problem is sql server management not work. as you can see the picture, after applying the following settings
=================================
Server Type : Database Engine
Server name: localhost
Authentication: Windows Authentication
==================================
Unfortunately I get the next image error, please help me solve this problem 
So did you install SQL Server or did you only install SQL Server Management Studio? SSMS is not SQL Server, and not is the SQL VSS Writer.
Check out the link in Dan's post above.
i downloaded and installed it from the link bellow
The link is for SSMS, the management tool and in your screenshot I don't see any SQL Server database engine service, so you don't have a running SQL Server, only the tool SSMS.
please help me how to connect to a SQL Server instance
You first need to install SQL Server: https://www.microsoft.com/en-us/sql-server/sql-server-downloads.
You cannot connect SQL Server, if you don't have SQL Server. And you don't.
Hi @Samir Abbasfard ,
Welcome to Microsoft Q&A!
I want to add something about what Erland said.
SQL Server is database engine while SQL Server Management Studio is GUI Administration Tool for working against the SQL Server engine.

Seeya
