Data Connectivity Solutions

Data network is a set of computers or devices connected to each other with the ability to exchange data from one point to one or more points (multipoint). Data networks may be composed of a variety of communication systems such as, circuit switches, leased lines and packet switching networks.

Data networking is a major and a complex part of the IT industry and almost all parts of the communication sector. Data networks could be categorized in to three major groups according to their geographical span.

  • Local Area Network (LAN)
    A network covering a small geographical area, like a home, office, or small group of buildings, such as a school.
  • Metropolitan Area Network(MAN)
    A network that connects two or more local area networks or campus area networks together but does not extend beyond the boundaries of the immediate city.
  • Wide Area Network (WAN)
    A computer network that covers a broad area (network whose communications links cross metropolitan, regional, or national boundaries).

Data Networking Devices

All data networks are built upon a hardware infrastructure which ensures a seamless end to end connectivity. These hardware devices could be composed of Network Interface Cards (NIC), Switches, Access Points, Routers and Firewalls. SIT has a good track record in installing, configuring and maintaining many customer networks which consists of a larger number networking devices. We also have been able to build a good image in the Sri Lankan business sector for our 24 hour services as well as strong island wide customer support.

Network Communication Media

As all the above mentioned networking hardware needs to be interconnected with high availability, networking media such as twisted pair cable, coaxial, optical fiber, power line or wireless links are deployed after considering some of the deciding factors (bandwidth requirement and environmental constraints etc..).

The devices in a data network could be placed in the same room or in different far away countries and still be connected without a problem as a result of these networking media. SIT is also involved in all the above mentioned data communication media, termination and connectivity projects and have successfully completed many projects with major companies in Sri Lanka.
