A domain is a logical grouping of computers or devices connected to the same or distinct types of networks. A centralised server handles each computer within a domain and administers it. A domain controller assigns unique domain names to these network domains, which are used to identify them. A domain controller serves as a server within a domain for the domain hosts, providing authentication services, domain names, and other services.
Secure access, in which no other computer outside the domain can access the domain computers, is one of the essential features of using a domain. The domain controller can also act as a storage database accessible by all devices in the domain.
The devices in a domain are under the control of a domain. It also has some characteristics like dependability, scalability, and so on. Therefore, some specialist software for creating and administering domains is required.
For these objectives, most operating systems include some built-in software. Domains are most commonly utilised in a 'Client-Server' model and are helpful when there are many machines. A network domain is typically used to subdivide a network or combine numerous networks with different architectures.
A workgroup is a collection of self-contained computers linked by a network and can share common data, resources, and tasks. It functions similarly to a workgroup in that it can be used to partition or categorise a network. The critical distinction is that it does not have centralised control over the workgroup's devices. For better management, it can be used to partition a vast network into workgroups.
Any server does not supply a workgroup name. In addition, assigning workgroup names is not reliant on any hardware components. In general, we assign workgroup names to devices, and they begin to function as a group.
A workgroup primarily uses a peer-to-peer networking architecture, in which each computer is self-contained, with its user account, permissions, memory, and importance. Furthermore, the security of these systems is questionable. They feature local security, which means that each device is secure in its own right. It's also possible that one computer in a workgroup doesn't have access to all other computers in that workgroup. Every machine must have its own set of user accounts and permissions.
Only machines from the same network can be part of a workgroup. A hub or a switch can be used to link these machines. It's simple to set up and configure, yet it's only valid for a few PCs. Most operating systems include applications for creating and maintaining workgroups. A workgroup is helpful in small local area networks such as schools, universities, and buildings.
The following table highlights major differences between a domain and a workgroup −
|Servers are one or more computers. Servers are used by network administrators to manage the security and rights of all computers on a domain.||Every computer is a peer; no computer has command over another.|
|You can log on to any computer on the domain without needing an account on that computer if you have a user account on the domain.||A set of user accounts exists on each machine. You must have an account on any computer in the workgroup in order to use it.|
|There can be more than hundreds of computers||There are usually only ten to twenty PCs in a room.|
|The computers may be connected to several local networks.||Computers must be connected in the same local network|
|Due to centralised governance, thedomain has very advanced security.||Due to the lack of centralised access management, a workgroup is significantly less secure.|
|Data from centralised storage can be recovered in a domain.||Due to each computer's local storage, data recovery in a workgroup is not possible.|
