| - | ====== Connectivity Infrastructure Overview ====== | ||
| - | |||
| - | The design of a communications network for any organization requires the following: | ||
| - | * a physical link such as a fiber optic or coaxial cable, a phone line, or radio link connecting the premises to the Service Provider | ||
| - | * a secure Internet connection from the Internet Service Provider (ISP) using the physical link | ||
| - | * a router for high-speed Internet connection of the internal network to the Internet | ||
| - | * firewall capabilities to ensure security of the internal network | ||
| - | * one or more data switches that link computers to one another inside the premises | ||
| - | * management and security software for all components of the network and IT infrastructure | ||
| - | * wireless (WIFI) access points and WIFI controllers that deliver wireless network access to the premises and immediate surrounds | ||
| - | * devices used by people for various library functions such as telephones, computers, tablets, scanners, printers, security cameras | ||
| - | |||
| - | The conceptual flow is that the ISP sends information to the modem, which connects to the router, which then connects the servers, desktops, printers, laptops and tablets , either wired or wirelessly. | ||

| - | A typical network infrastructure includes: | ||
| - | * External Network Services: | ||
| - | * High Speed Internet link | ||
| - | * Fibre Internet Link | ||
| - | * Coaxial Cable | ||
| - | * Line of Sight Radio Link (microwave) | ||
| - | * Digital Subscriber Link (DSL) | ||
| - | * Satellite | ||
| - | * Networking Hardware: | ||
| - | * firewall | ||
| - | * routers | ||
| - | * switches | ||
| - | * Wireless routers and Access Points (WAP) | ||
| - | * cabling | ||
| - | * electrical power | ||
| - | * Networking Software: | ||
| - | * Domain Name Service | ||
| - | * Network Address Translation (NAT) | ||
| - | * Network Segmentation (VLAN) | ||
| - | * Network security applications - Intrusion Detection, threat prevention, Cybersecurity solutions | ||
| - | * Network operations and management | ||
| - | |||

| - | The aim of this guide is hopefully to deepen your understanding of connectivity and assist you in procurements and planning without overwhelming you with acronyms. | ||
