What Is Ict Infrastructure Information Technology Essay
The Network Design include the process to design a topology, to synthesize a network and to create this network. This process sometimes changes for the needs of the network and services. The Network planning and design are created to meet the needs of users.
Network software is used to share important information among computers.
Networking Hardware is the equipment used to build the network and includes routers, access points, switches, hubs, network interface cards, gateways, cables, modems and other materials and devices.
The Computer Network Systems and Telecommunications use communication protocols to describe digital message formats and rules for exchanging them. These Protocols include signaling, authentication and error detection and correction capabilities.
Network Security is the specialist area and a part of networking and includes the policies and provisions adopted by the network administrator. This is achieved by Firewalls and user’s authentication.

What are the main characteristics that an organisation may require from a network and infrastructure design?
– Redundant number of network nodes, including servers, routers, terminals
– The infrastructure depends upon the organisation requirements and characteristics such as the building or area that the network must cover, the amount of data that needs to be stored, the nature of the communication (wired / wireless / hybrid), the need for mobility of the users’ terminals
– The financial cost that the organisation can afford. Parameters like the skills of the staff that will use the final network, the number of technical staff for the IT support, the dynamicity degree of the system design (how often the network will need to be updated, expanded, changed) and the required network lifetime

How does it differ from traditional network management and administration?
Network management include the methods, procedures, activities and tools for the operation, administration, maintenance, and provisioning of networked systems.
Network administration is a modern professional job for the maintenance of computer software and hardware that consisting a computer network. Usually includes deploying, configuring, maintaining and monitoring active network equipment and network devices, for example routers, hubs, and switches. A related role is that of the network specialist, or network analyst, who concentrates on network design and security.
