Apple iPhone text “Effective Power” – Fix

This may work for you and it may not.  If you haven’t heard, there is apparently some bad formatted text? that you can send across through an iPhone that can cause your phone to shut off or reboot.

If you get a text that says Effective Power (which is also followed by other stuff) which causes your phone to reboot or power off, go to your photos app and send any picture to whoever sent the text to you.  Now open your messages and this should be gone or you can delete the message.

You may also try sending a message by Siri.  If you can’t find their number, say “Siri, send ‘whatever’ to my latest text”.

Hopefully this will stop the messages and the phone problems many have reported.

Going to take a certification that involves binary?

Going to take a certification that involves binary?

Here’s a quick tutorial~

Let’s say you are given an IP address of 192.168.1.135 in an answer.

What is this number in binary?

Here’s what you do.

Take a simple key to convert the numbers in the octets into binary.

The key is this:

128   64   32   16   8   4   2  1

Now let’s take the first octet of 192 and let’s see how many times the numbers above (the key) go into the given octet.

How many times does 128 go into 192?     192 – 128        1 time

This will leave us 64.

Next, how many times will 64 (your remaining number) go into the next number in the key(64)?

64 -64       1 time

Now the remaining number is 0.   So if you subtract 32 from 0 the number will be 0.  16 from 0 is 0, 8 from 0 is 0, 4 from 0 is 0, 2 from 0 is 0 and finally 1 from 0 is 0.

Look at your answers. 11000000 -This will represent 192.

Now let’s do the 168 octet.

128 goes into 168 – 1 time.   The remaining number is 40.   64 goes into 40 – 0 times.    32 goes into 40 – 1 time.  This gives you a remainder of 8.   16 (the next number in the key) goes into 8 how many times? 0 . 8 goes into 8 – 1 time.  The remainder is now 0.    4 goes into 0 – 0 times.   2 goes into 0 – 0 times.  1 goes into 0 – 0 times.   Look at your answers (bold).

168 will be 1010100

Of course the next number (third octect) which is 1 will be 00000001.

If you use the above key for 132, along with the subtraction method, 132 will be 10000100.

Your final answer is 11000000.1010100.00000001.10000100

Try a these yourself using the subtraction method above –

192.168.1.32

192.168.1.111

Flip over and see the answers

11110110˙10000000˙00010101˙00000011

01100100˙10000000˙00010101˙00000011

The easy way to subnet your network

Why?  The Golden Question

All over the internet you will find information on ‘How to Subnet’.   Suddenly you are thrown into a world of bits and binary and given charts of ‘How to Subnet’.   But why do you subnet?

Subnets are created to separate areas of your network for security and/or to hold down broadcasts.  Computers constantly ‘talk’ to each other.   If you have a network of 10 computers, the talking (opening files or programs) or broadcasting packets that are sent out during networking is not much traffic at all.   However if you have 10,000 computers talking and passing data, you will have thousands of computers passing data and your network will slow down from all of the information.   If you still don’t understand, invite 10 friends over for a get together.  It’ll get noisy but you can still hear every conversation.    Now, go to a rock concert with 10,000 screaming fans.   Get the picture.

Subnetting allows you to divide areas of your network out to prevent this.   So here comes the golden question.  How can you get them to ‘talk’ when you need to?   With the installation of a Layer 3 Switch or a router, these subnets can talk.

And for all of the folks who know a ton of details on the subject, this is just an example for people who are searching why to subnet.

Subnetting allows your network to become more efficient and allows you to separate your network by subnets.

Let’s say your network is on a 192.168.1.x numbering scheme.

How do you know what your network is?  Open a command prompt and type ipconfig.   See the gateway?  That is your starting number for your network.   The network allows 254 computers to be in the broadcast domain.

So if you do an ipconfig and see this-

192.168.1.125      – your ip address
255.255.255.0    – your current subnet
192.168.1.1           – your gateway (This is your router or firewall – the point leading to the internet)

Now let’s say you have 20 devices in your network.   How can you effectively hold down broadcast and prevent your router from building tables for each device?  How can you make it more effective and hold down traffic?   Actually without understanding binary, you can do this.   Remember this is basics and should help you understand.

You see under the current network, you can have 254 devices in your network.  Printers, routers, computers, tablets, netbooks, notebooks, etc.    The last set of numbers called an octet only goes from 1-254.   But lets narrow this down.

You can use a CIDR calculator online to determine how to tweak your network.   A good site is Subnet Calculator.   Go there and enter your router’s number in the ip field.   Now go down and enter a number close to the number of devices you have on your network.  In this example, enter 30.

Did you see where the subnet changed to 255.255.255.224?    (Did you notice that 224 + 30 is 254?)

Ok, now open your adapter settings by clicking the network icon at the bottom right corner and selecting Open Network and Sharing Center.

Now click on the adapter settings.

Right click and select properties on your adapter that is active.

Now select Internet Protocol v4

Enter an ip address statically (manually put it in).  Put in your new subnet and your gateway.   You must also put in your DNS or a public DNS server.  You should keep a list of each devices number to avoid any problems.  All ip addresses must be different on each device.

The only valid numbers in this broadcast domain now is – 192.168.1.1, 192.168.1.2, 192.168.1.3 continuing until you get to 192.168.1.30 (remember you chose to have up to 30 devices on your network.)  If you enter any number above this, you will get an error.

Error screen showing an ip address above what you selected.

If you get the above error screen, you have entered an invalid number.

After you select a number between 192.168.1.1 and 192.168.1.30, click OK and exit all screens by clicking OK.

If you do an ipconfig now, you will see this-

When you change subnets as the above example shows, you have to remember that you may lose connectivity to devices such as routers or network printers.   You will need to set devices such as servers and these devices on the same subnet so that whoever is assigned this subnet can communicate with them.

This by no means is a thorough subnetting lesson.   It can become much more complex by introducing multiple routers into your network, DHCP servers or other devices.   This is a simple how-to that shows you how broadcast domains can be more efficient.
