They are commonly used in environments where large volumes of data need to be stored and accessed, such as banking, e-commerce, and customer service. 

c. File Servers 

File servers are used for storing and sharing files across a network. They facilitate access to documents, media files, and other data by users within the organization. File servers are particularly important in environments where document sharing and collaboration are essential. 

d. Email Servers 

Email servers manage and facilitate the sending, receiving, and storage of emails. These servers allow users within an organization to send messages and store incoming correspondence securely. Email servers can be used for both internal and external communication. 

e. Application Servers 

Application servers provide an environment for running applications. They host the software programs that users access over the network. These servers are often used to support client-server applications, where users interact with an application on the client side, and the application logic is processed on the server side. 

f. Virtual Servers 

Virtual servers are not physical machines but rather software-based servers that run within a physical host server. Virtualization technology, such as VMware and Hyper-V, allows one physical server to run multiple virtual servers, each acting as an independent server. This provides greater flexibility and resource utilization and is commonly used in cloud computing environments. 

g. Proxy Servers 

A proxy server acts as an intermediary between client devices and the internet. It forwards client requests to the internet and returns responses back to the client. Proxy servers can be used for a variety of purposes, including enhancing security, controlling internet usage, and improving performance by caching frequently accessed content. 

h. Print Servers
