Explanation / Answer

Disadvantages of dynamic IP address

-Using dynamic IP address means our Internet provider will constantly change our IP address usually every hour which results in a gap in the user's connection. Our machine sometimes can also have trouble connecting to Intternet again as soon as our IP is changed

-Dynamic IP address needs an extra effort from administrators to setup since there requires a seperate program to constantly change the IP's.

Disadvantages of Static IP

The major disadvantage of static IP is security,since our machine is running on a constant IP it becomes vulnerable to hacking because hackers need not concentrate on chnaging Ip's they just have to hack 1 IP.

Static IP's are mainly used by servers which is connected by a lot of computers .To maintain the connection with all computers in network a server has to be up all the time which is quite costly.

ans7)functionality of a global catalog in the Windows networking

A global catalog searches for the objects in all domains regardless of where data is stored.

A global catalog server resolves a user principal name when the authenticating domain controller has no idea of the user account

It Supplies universal group membership information in a multi domain setup.

8)difference between permissions and rights in networking

2. Permissions are handled by Access Control Lists

RIGHTS are given to Security Principles and they are system related not object related for example rights are applied to change settings of system, any screen

2. Rights are handled by Security Policies.
