Answer:
b. Associativity
Explanation:
Associativity specifies the order in which operators are processed vis a vis operands/values in an expression. For example: Consider the expression: a + b + c. Here a + b is evaluated first before adding the result with c as the '+' operator is left associative. The default associativity can also be overridden by the use of parentheses. For example a + (b + c) . In this case b+c will be evaluated first.

Answer: EMI(Electromagnetic interference)
RFI(Radio frequency interference)
Explanation: Electromagnetic interference is the emission of the electromagnetic signal that can disturb the working of the other device.It invokes the disturbance that can create error, under-performance mechanism,distortion etc in the equipment.
Radio-frequency interference(RFI) is the radio-frequency signal that interferes the other device by creating noise and distortion. This leads to breaking of the operation and data error.
Other options are incorrect because cross talk is referred as undesired communication between signal ,attenuation is the degradation in the amplitude of any signal and extended length of cabling is increasing the length of the cable.Thus the correct answer is RFI and EMI.
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).
