Complete Question:
1. A wireless technology standard for exchanging data over short distances
2. A particular brand of mobile phone/PDA
3. A network that operates over a limited distance, usually for one or a few users
1. Bluetooth
2. PAN
3. Blackberry
Answer:
1. Bluetooth 2. Blackberry . 3. PAN
Explanation:
1. Bluetooth is a wireless technology standard, used in order to exchange data between mobile devices, like smartphones, tablets, headsets, wearables, over short distances in a one-to-one fashion (which means that it is not possible to build a network based in Bluetooth).
2. Blackberry is a brand of mobile phones/PDAs, very popular a decade ago, because it was the first one to allow mobile users to access e-mails and messages from anywhere, at any time.
3. PAN (Personal Area Network) is an ad-hoc network that it is only available for data exchange at a very short distance, within the reach of a person, i.e. a few meters as a maximum.
It is thought to allow someone to interact with his nearest environment (laptop, tablet, PDA) and it can be wireless (like Bluetooth) or wired (via USB cables).

Answer:
its easy
Explanation:
there are are 5 main rules
in binary there are 2 number 0 and 1
0 + 0 = 0
0 + 1 = 1
1+0=1
1+1=0 carry 1
e . g
1 1 1
1 0 1 0 1 0
+ 1 1 0 0 1 0
-------------------------
1 1 1 1 1 0 0
*in bold are the ones that you need to carry.
in decimal there are 10 possible numbers 0- 9
when you do 1 + 9 it becomes 10, this can be done easily, however if you do 1 + 9 in a table like above, you will get 0 for the first column and you will carry 1 to the next column .
in binary is the same idea but using on 2 numbers 1 and 0
e.g
1
1
+ 9
----------
1 0
*in bold are the ones that you need to carry.
hope it helps and good luck in your exam.
