As a management tool, a LAN can:
Increase system performance through the distribution of tasks and equipments, improve the availability of computer resources. Tasks can be assigned to several machines; increase system reliability. Crucial processes can be duplicated and/or divided so that, on the failure of one machine, other machine can quickly take up the load. Minimize the adverse effects of loss of any one system. Help regain administrative control of equipment, LAN improves the efficiency with more information accessible at workstation which can be used for taking better and timely decision. LAN can have dramatic impact on efficiency where the data is dynamic. The LAN server concept allows efficient centralization of information by allowing control over who uses the network and for what purpose. A LAN has extensive security system. A LAN has configuration flexibility. PCs and other resources can be added as and when needed.
The advantages of local area networks can be enumerated:
- Local area networks are the best means to provide a cost-effective multiuser computer environment.
- A LAN can fit any site requirements.
- It can be tailored to suit any type of application.
- Any number of users can be accommodated.
- It is flexible and growth-oriented.
- It offers existing single users a familiar Disk Operating System (DOS) environment.
- It can use existing software if the original language supports multi-user environment.
- It offers electronic mail as an in-built facility.
- It allows sharing of mass central storage and printers.
- Data transfer rates are above 10 Mbps.
- It allows file/record locking.
- It provides foolproof security system against illegal access to data.
- It provides data integrity.
