Network solutions
A network is a set of devices (often referred to as nodes) connected by communication links. A
node can be a computer, printer, or any other device capable of sending and/or receiving data
generated by other nodes on the network.
A network must be able to meet a certain number of criteria. The most important of these are performance, reliability, and security.
- LAN
Local area networks, generally called LANs, are privately-owned networks within a single
building or campus of up to a few kilometres in size. They are widely used to connect personal
computers and workstations in company offices and factories to share resources (e.g., printers)
and exchange information.
- mAN
A metropolitan area network, or MAN, covers a city. The best-known example of a MAN is the
cable television network available in many cities. This system grew from earlier community
antenna systems used in areas with poor over-the-air television reception
- WAN
A wide area network, or WAN, spans a large geographical area, often a country or continent. It
contains a collection of machines intended for running user (i.e., application) programs. These
machines are called as hosts. The hosts are connected by a communication subnet, or just subnet
for short
- Client Server Systems
These are the most common types of network operating systems and they are frequently used in business, government, schools and other organizations that require a central server. The server houses all of the files for the network, and each computer is tied into the server.
- Peer-to-Peer Network
These networks are far less common as they involve storing the files on individual computers rather than a centralized network. This means each computer must share hard-drive contents with all other computers on the network. Collectively, the computers make the network possible. This model is more common when used by a single individual while connecting multiple devices.
- Cloud Based Alternatives
While network operating systems are highly valuable in many businesses, they are not always necessary. Cloud based storage and browser based software has changed the way many businesses operate. Cloud based systems are more effective and efficient in most cases. The only downside to the cloud systems is the need for connectivity.A stable connection to the cloud is mandatory for file access.
