Subnet Mask

Posted by 5 February, 2019 (0) Comment

A subnet mask is used to detect the IP address that is reserved for your network and the one available for use by the host. The subnet mask offers you all the information that you need to calculate the network and host portions of the address with great ease. With the subnet mask you can calculate whether the IP addresses are in a similar subnet.

The subnets are necessary for the IP network communications to carry on. The network devices use the IP addresses and a defined subnet mask to determine if the host is on a remote subnet or local subnet.

It makes it easy to identify the number of hosts capable of being included on the same subnet.

RG 58

Posted by 5 February, 2019 (0) Comment

RG-58 is a coaxial cable (electrical cable with an inner conductor that’s surrounded by an tubular insulating material) that is used for wiring especially on RF (radio frequency) communication systems. The RG58 cable is mostly used in 2-way communication systems like police radio calls and amateur radio, wireless LAN antennae, marine SSB and VHF. The cable is also the generic carrier of signals in laboratories and works in combination with BNC connectors to test and measure equipments like oscilloscopes. However, there are some limitations to the use of RG58 cables as they only support a maximum of 30 nodes in a distance of 185 meters.

They are used to setup 10B2 networks that have a bus topology thus any changes affect the entire network.
