The network switch is an essential piece of equipment in all modern place of work, or place of business. The sharing of internet, printer or computer files requires network switches. If you install a under-performing piece of equipment, your business will suffer, productivity will be affected, and ultimately your business revenue will drop.
The way to solve this problem is to select the right switch
Managed or Un-Managed - Un-Managed switch is a plug and use device, no setup configuration, no installation software required. It should be a basic feature rich ethernet switch without the complexity of managed switch. Until such a time that your IT Infrastructure requires a managed switch, un-managed switch will serve your needs adequately. You can even run surveillance IP Cameras, IP Telephony and Wireless Access Points (AP) on a network of un-managed PoE+ switches.
Ports - each port is 1 ethernet cable connection. Network switches commonly come in 8-port, 16-port and 24-port configurations It is important to have enough ports, and provision for extra ports against future needs.
Port Baseband - the transmission speed of each port, measured in Megabits per second (Mbps). The common basebands are 10 Mbps, 100 Mbps and 1000 Mbps, also seen as 10/100/1000. Choose a 1000 Mbps also known as a Gigabit switch, the price difference is negligible compared to it's long term usefulness.
Port Buffer Size - the buffer for pre-load of data packets, to speed up future reads. This feature is important in IP Camera or IP Telephony application. A good port buffer size is at least 4 Mbits for a 24 port switch.
Switching Capacity - the amount of data that can travel through a switch, measured in Gigabits per second (Gbps). A network switch can have many ports, but how much traffic can it actually handle? A good capacity for PoE switches used for; Camera Surveillance, IP Telephone or Access Points, is 48 Gbps for 8 port, 16 port or 24 port switches.
Forwarding Capacity - the number of network packets that can be processed by the switch, measured in packets per second (Mpps). Recommended minimum of 6 Mpps for a 24 port switch.
Note:   in network bandwidth capacity or speed, there is a big difference in small b which denotes bits, and capital B which denotes bytes. 1 byte = 8 bits.
