Looking forward to this, always struggle to explain stuff like this to laymen
None of the analogies I use make sense to them

Your DHCP server, your router, issues (leases) IPs within a fixed range*. Device 1 will tend to always get the 1st IP in the range x.x.x.001. Device 2 then gets x.x.x.002 and so forth for every device becoming active on the network. This means that each device has a unique IP in the end. If you now want to introduce a static IP device onto this network your best bet would be to always assign a high IP within the range (in this case I went for x.x.x.240) as the chance of your (home?) network having enough devices to actually saturate the range all the way to x.x.x.240 is rather slim. In other words, for your router to actually issue the ip x.x.x.240 and cause an IP conflict (something that we don't want) it would need to have issued all the 240 odd IPs before that already to 240 odd live devices in your network. Once again, I assumed this was a home network and that you would not have so many devices. To add to this, I never go for the top range x.x.x.(250-255) as I've seen some routers use this for their own.
In your specific case the gateway/router was 192.168.10.001 and I assumed that 192.168.10.240 would not be issued and thus be available.
*I've had a look at your router and it is set, by default, to only issue IPs from a fixed range/pool of 100 IPs starting from ~192.168.10.101. The IP we assigned to your PC is 192.168.10.240 and is thus outside of any IP conflict danger. We could have used any IP, 192.168.10.249, as long as long as it was not in use or was in danger of being issued by your router easily in the course of normal use.
Why?

Do not stress. Your router makes use of a completely private IP namespace: 192.168.0.0 - 192.168.255.255
None of these IPs can be 'reached' in a manner of speaking by the internet as they are only designated for private internal network use.
Curious to know why Secondary is " 8.8.8.8" ?
Is this a default IP if u don't have a specific IP ?
8.8.8.8 is one of Google's public DNS servers

As mentioned above, 8.8.8.8 is a service provided by our dear old Google. Should your ISP have some kind of a DNS failure your PC will route DNS requests to the secondary DNS. It is also easy to remember - a big plus. In the past DNS failures happened more than what one would like to admit but these days not so much. I just tend to still do it ... 'just in case'.
The DNS converts the www.mybroadband.co.za, that you type in, to the actual computer IP, 41.203.21.137 in this case, so that your computer knows who to call up each time you open up this site.
