Network operating system

The term network operating system is used to refer to two rather different concepts:

Network device operating systemsEdit

Network operating systems can be embedded in a router or hardware firewall that operates the functions in the network layer (layer 3).[2]

Historic network operating systemsEdit

Early microcomputer operating systems such as CP/M, DOS and classic Mac OS were designed for one user on one computer. As local area network technology became available, two general approaches to handle sharing arose.

Peer-to-peerEdit

In a peer-to-peer network operating system users are allowed to share resources and files located on their computers and access shared resources from others. This system is not based with having a file server or centralized management source. A peer-to-peer network sets all connected computers equal; they all share the same abilities to use resources available on the network.[4]
The advantages include:
  • Ease of setup
  • Less hardware needed, no server need be acquired
The disadvantages include:

Client-serverEdit

Network operating systems can be based on a client–server model (architecture) in which a server enables multiple clients to share resources.[1] Client-server network operating systems allow networks to centralize functions and applications in one or more dedicated file servers. The server is the center of the system, allowing access to resources and instituting security. The network operating system provides the mechanism to integrate all the components on a network to allow multiple users to simultaneously share the same resources regardless of physical location.[4][5]
The advantages include:
  • Centralized servers are more stable.
  • Security is provided through the server.
  • New technology and hardware can be easily integrated into the system.
  • Hardware and the operating system can be specialized, with a focus on performance.
  • Servers are able to be accessed remotely from different locations and types of systems.
The disadvantages include:
  • Buying and running a server raises costs.
  • Dependence on a central location for operation.
  • Requires regular maintenance and updates.

It was established on 1 July 1949 as a  statutory body  under the Chartered Accountants Act, 1949  enacted by the  Parliament  (acting as the provisional Parliament of India ) to regulate the profession of  Chartered Accountancy  in India. ICAI is the second largest professional Accounting & Finance body in the world. However, the rapid growth and autonomy of the ACCA in the early 2000s, soon made ICAI the third largest in terms of membership, the first being the ACCA. ICAI is the only licensing cum regulating body  of the  financial audit  and accountancy  profession in India. It recommends the  accounting standards  to be followed by companies in India to  National Advisor...

Local aria network

LAN A conceptual diagram of a local area network. "LAN" redirects here. For other uses, see   LAN (disambiguation) . A   local area network   ( LAN ) is a   computer network   that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. [1]   By contrast, a   wide area network (WAN) not only covers a larger geographic distance, but also generally involves   leased telecommunication circuits . Ethernet   and   Wi-Fi   are the two most common technologies in use for local area networks. Historical technologies include   ARCNET , Token ring , and   AppleTalk . History Cabling Edit Early LAN cabling had generally been based on various grades of   coaxial cable . Shielded twisted pair   was used in IBM's   Token Ring LAN implementation, but in 1984,   StarLAN showed the potential of simple   unshielded twis...
