The IP information that has been assigned to the machine, such as the DNS IP address and gateway IP address, is displayed using the IPCONFIG command.
2) What is a domain?
A domain is a collection of computers that the internet’s network recognises. Computers with central administration can utilise it. When you instal Active Directory, it is produced.
3) What is a Ping command?
Ping is used to verifying physical IP connectivity between two or more devices.
4) What is a group?
A group of user accounts is referred to as a group. It offers network administration that is streamlined.
5) What is the child domain?
The member domain of Windows 2000 Active Directory is a child domain.
6) What is OU?
For organizational units, use OU. It is an Active Directory container that can house computers, groups, and users. It is the smallest unit to which a group policy setting can be applied by an administrator.
7) What is group policy?

9) What is OS?
An operating system (OS) serves as a conduit between computer hardware and users. An operating system is a piece of software that manages files, memory, processes, input, output, and peripheral devices like disc drives and printers. It also handles input and output.
10) What is DHCP?
Network administration protocols include DHCP (Dynamic Host Configuration Protocol). When a network-connected device requests an IP address from the DHCP server, the server gives the device a special IP address.
11) What is DNS?
The Internet’s method for turning alphabetic names into numeric IP addresses is called the DNS (Domain Name System). For instance, DNS servers deliver the IP address of the Web server associated with a Web address (URL) that is entered into a browser. The DNS transforms www.crackso.com into the IP address 204.x.x.x in this fictitious example. Without DNS, retrieving the webpage would require entering a string of four numbers and dots into your browser, which is something you can do.
12) What is BSOD?

A client and server on a computer network can transmit data using the File Transfer Protocol (FTP), a common network protocol. One fantastic feature of FTP is its ability to restore a previously broken connection and begin uploading or downloading from that point on. FTP also permits the simultaneous transfer of multiple directories in addition to numerous files.
14) What is DFS?
A distributed file system (DFS) allows any number of remote clients connected to a network to store and access files from one or more central servers with the necessary permission rights. DFS can be helpful because it makes it simpler to deliver documents to several customers and because it offers a centralized storage system that prevents client machines from being overloaded with files.
15) Difference between Differential and Incremental back ups?
Only the files that have changed since the last full backup are backed up in a differential backup. Additionally, incremental backups only store updated data, but they only store modified data since the last backup.

Domain Naming Master
Schema Master
RID Master
PDC Emulator
Infrastructure Master
