Posted by 7 January, 2020 (0) Comment

A satellite dish is a type of an antenna that receives microwaves from communication satellites and then transmits the data. This link provides insights on the best way to get best satellite dishes. Size is of ultimate importance because the larger the dish, the more signals it’s likely to receive. A bigger dish is also suitable for places which experience long periods of rain. The oval-shaped dish is the best as it can simultaneously pick up multiple signals from different satellite locations.

The dish should also be well fixed to a mechanized motor where it can easily turn in order to pick up signals. Satellite dishes are of different types: TV satellite dish, satellite receiver and DISH network satellite dish.

This is a computer system used to monitor and control processes related to infrastructure, industry or based in a facility. These systems usually consist of four subsystems that include the Human – Machine Interface, Remote Terminal Units, Programmable Logic Controller and Communication.

SCADA systems are usually confused with Distributed Control Systems but the difference is that processes are not controlled in real time. Changes in the networking technology have an effect on these systems with protocols based on TCP/IP and Ethernet replacing older standards.

These systems are popular because there is more convenience when viewing processes from remote areas. The change solutions that are more standardized and open and increase in internet connections, have made SCADA systems more prone to attacks.
