Different types of Servers

Different types of Servers used in networks are listed below.

File Server: File servers are used to store the user documents and files centrally. An ideal file server should have a large amount of memory and storage space, fast hard-disks, multiple processors, fast network adapters, redundant power supplies etc.

A File server runs FTP (File Transfer Protocol) in Windows, Linux or Unix Networks, or SMBP (Server Message Block Protocol) in Windows Networks. Well known FTP software products are Micrsoft IIS, vsftpd, Apache FTP Server etc.

The main advantage of keeping network user files and electronic documents centrally in a file server is that the network user files and documents can be managed (backup'd) easily. Think about managing network user files and electronic documents kept distributed inside user workstations in a network consists of thousands of computers! Nearly impossible.

Print Server: Print Server, which redirects print jobs from client computers to specific printers.

Mail Server: Mail Servers are used to transmit emails using email protocols. Most widely used email transmission protocol is SMTP (Simple Mail Transfer Protocol). Mail Servers exchange emails between different domains.

Most widely used Mail Server software products are Microsoft Exchange Server, SENDMAIL (now proofpoint), qmail,Postfix etc.

Application Server: Common computer applications or programs which are required by different network users can be run in a central server, which enables multiple network users to access common network applications from the network. Typically Application Servers run business logic. Which means, every business is different and the Application Server is the Server Software which controls the business process. Some examples for Application Server Software are SAP BASIS, WebLogic, WebSphere etc.

Database Server: Database Server allows authorized network clients to create, view, modify and/or delete an organization's data, stored in a common database.

Examples of Database Management Systems are Oracle 10g/11g, Microsoft SQL Server 2000/2005/2008/2012, PostgreSQL,IBM DB2, MySQL, Sybase, Informix etc.

Directory Servers: Directory Servers allows the central administration and management of network users and network resources. Directory Servers provide the basic functions of network security, Authentication, Authorization and Accounting.

Examples of Directory Servers are Microsoft Active Directory, NetIQ eDirectory, Fedora Directory Server, OpenLDAP etc.

Another logical classification of computer networks is Centralized and Distributed Computer Network Model.

Centralized computer network model

In Centralized computer network model, the network resources are placed and managed from a main location. Centralized network model allows administrators to manage the resources centrally (typically in Head Office). The network servers and other critical network resources are located in a central location in a secure and dedicated server room.

Centralized network model provides following advantages to Network and System Administrators.

Centralized network model provides Network and System Administrators better access to network devices

In Centralized network model, Network Resources can be managed more easily

Centralized network model provides better Network Security.

The main disadvantage is more work load of Network and System Administrators and increased risk of communication failure due to a catastrophe in the central location.

Distributed network model

In Distributed network model, the network resources are placed and managed from different geographical locations. Designated network and system administrators manage the network resources in different locations. These days most of the Enterprise network models are distributed.

                                                                       

Internetworks

Internetworks

Before discussing about the terms internet, intranet and extranet, we need to discuss the term Internetwork.

An internetwork can be defined as two or more computer networks (typically Local Area Networks LAN) which are connected together, usinng Network Routers.

Each network in an Internetwork has its own Network Address, which is different from other networks inside the Internetwork. Network Address is used to identify the networks inside an Internetwork.

Internetwork allows different users at different geographical locations of an organization to share data, resources and to communicate. Modern businesses cannot even function without Internetwork. Internet, Intranet and Extranet are different types of internetwork.

Internet, Intranet and Extranet

             

Internet: Internet is a worldwide, publicly accessible computer network of interconnected computer networks (internetwork) that transmit data using the standard Internet Protocol (IP). Internet is the world's largest Internetwork .

The terms World Wide Web (WWW) and Internet are not the same. The Internet is a collection of interconnected computer networks, linked by copper wires, fiber-optic cables, wireless connections, etc. World Wide Web (WWW) is a collection of interconnected documents and other resources, linked by hyperlinks and URLs. The World Wide Web is one of the services accessible via the Internet, along with various others including email, file sharing, remote administration, video streaming, online gaming etc.

Intranet: An intranet is a private network that is contained within an enterprise. It may consist of many interlinked local area networks and use any Wide Area Network (WAN) technologies for network connectivity. The main purpose of an intranet is to share company information and computing resources among employees. Intranet is a private Internetwork, which is usually created and maintained by a private organization. The content available inside Intranet are intended only for the members of that organization (usually employees of a company).

Extranet: An extranet can be viewed as part of a company's intranet that is extended to users outside the company like suppliers, vendors, partners, customers, or other business associates.

Extranet is required for normall day-to-day business activities. For example, Placing order to registered vendors, Billing & Invoices, Payments, Joint Ventures, Product Brochures for Partners, Discounted price lists for partners etc.

Difference between Windows 2003 Basic and Dynamic disks

Difference between Windows 2003 Basic and Dynamic disks

Physical disk drives are hardware device that can be installed or attached to a computer for data storage purpose. Windows 2003 should automatically detect any disk drive you install the computer. The main tool which ships with Windows 2003 for disk management is Disk Management MMC snap-in. You must be a member of the local Administrators group, the Backup Operators group, or have been delegated permission to manage basic and dynamic disks. To format a disk, you require administrator privileges. Windows 2003 supports two storage types; Basic disks and Dynamic Disks. Basic Disks Basic storage uses normal partition tables supported by MS-DOS, Microsoft Windows 95, Microsoft Windows 98, Microsoft Windows Millennium Edition (Me), Microsoft Windows NT, Microsoft Windows 2000, Windows Server 2003 and Windows XP. A disk initialized for basic storage is called a basic disk. A basic disk can have up to four primary partitions or up to three primary partitions and one extended partition. Each primary partition is represented with one logical volume. Each extended partition is represented by one or more logical drives. Dynamic Disks Dynamic storage is available in Windows XP Professional, Windows 2000 and Windows 2003 Server. A disk initialized for dynamic storage is called a dynamic disk. A dynamic disk contains dynamic volumes, such as simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes. With dynamic disks, we can create fault tolerant volumes. Non-fault tolerant volumes provide no data redundancy. If a non-fault tolerant drive fails, the data can be recovered only from backup. Fault tolerant volumes provide data redundancy. If a fault tolerant drive fails, you can rebuild the volume without having to recover data from backup.
