Is this ok [y/N]:y

Yum will try to install httpd and also will check and show you dependencies, in our case we httpd is already install so yum will auto update httpd as shown above.
In our case httpd (2.2.3-5) is already install

[root@localhost RPMS]# rpm -qa | grep httpd
httpd-2.2.3-5
[root@localhost RPMS]#

so yum showed the new version as update 2.2.6-1.fc6
