What is data transmission?

Data transmission is the transfer of data from point-to-point often represented as an electro-magnetic signal over a physical point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, and storage media. The term usually refers to digital communications (i.e. digital bit stream), but may include analog data transmission as well. Data transmission is a subset of the field of data communications, which also includes computer networking or computer communication applications and networking protocols, for example routing and switching.

Why A tradition phone line has a sampling rate of 2400 baud but a baud is not a bit while the data transfer rate of telephone line is greater then 2400 signal per second?

Baud rate is the number of samples per second. Data transfer rate is the number of bits per second. Since the analog phone line can have more than two values at any one sample, this translates to more bits per second than baud.

There is a tendency to confuse baud rate with data rate. The two terms are not always the same.

Address of a float can be assigned to a char?

No. The address of a float can only be assigned to a variable of type pointer to float. Any other (coerced) use is outside of the definition, implementation, and portability of the language.

Yes, with typecast, but it is entirely pointless:

float f;
char c = (char)&f;

How long does it take to become network security engineer?

There is no definite answer for this question. It depends on your level of interest and ability to absorb working security practices (and apply them effectively to secure any system).

You can go about trying to get certified in this field; Look into:

CCSP - Cisco Certified Security Professional

CISSP - Certified Information Systems Security Professional

There are specializations still as a Network Security Engineer:

Have a look at the GIAC Certifications: http://www.giac.org/certifications/

You can start by knocking down one of the most basic certifications:

CompTIA Security+

How much a crestron programmer makes?

It depends on the level of experience and wether or not you're certified and what level of certification you have (ie: Certified, Master Certified, Silver, Gold or Platinum), plus of course your level of expertise on A/V if it's residential or commercial etc. But on average it starts around $45K for basic level programmers with minimum A/V knowledge, all the way up to $150K for Certified programmers with good A/V knowledge and experience. It also depends which company it is, and where the company is located usually northern states or out west, down here in the south salary range are very low.
