Because the costs are small than other kind of transmissions. For example, in case of 8 bits data transmission, parallel aprouch needs 8 wires but serial only 1 (cheapest).

Why AC current is transmitted from power station instead of DC current?
This was due to the results of the War of the Currents between Edison, who supported DC and Tesla for AC power distribution. Although most electronics you find today run off DC power, the transmission of DC power over long distances is not very efficient and requires several substations between the power transmission source and where it is received. AC power after stepped up can be transmission over long distances with little energy loss. The energy loss occurs from heat generated from resistance within the transmission wire. At the introduction of Edison's system, there was no practical AC motor available. It was primary due to the introduction of the 3 phase AC motor did AC finally win over DC.
Why is a wrench with a long handles preferred to unscrew a nut?
Longer the handle-the more leverage
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
Short distance transmission of power is done at higher voltage or higher current?
High voltage is used to transfer power over long distances ONLY because the gauge of the wire can be smaller. Power transfer is always most efficient at the operating voltage if the size of wire is not an issue.
Why step up transformer is required to send energy at long distances How energy losses reduces by using step up voltage while sending it to long distances?
Power is basically voltage times current. The power lines have resistance and that causes a loss of some power in transmitting the power over long lines. When the power is sent at a higher voltage, the current is lower, which means that the power lost in the wires is less. A rule of thumb for power transmission is to use 1000 volt per kilometre so for a 33 km line you would use 33 kV.
What is the Preferred two man carry for long distances?
fore and aft
What is serial transmission?
Serial transmission is a method of transmitting data where one bit is transmitted after another in a single wire. Serial transmission is usually used to transmit data between two computers as it is less expensive, yet at a cost of a slightly slow speed. A minimum of two wires is needed for serial transmission, which is less compared to a minimum of eight wires in parallel transmission. Serial transmission is used to send data over long distances as the bits are less likely to get out of order. It is used in devices such as modems, bar code readers and light pens .
Which port is used to transmit slow data over long distances?
Serial ports
What are long-haul applications?
It is when transmission distances are greater than five miles
Is a wireless transmission medium that distributes radio signals through the air over long distances?
broadcast

What are the three types of distances?
Short distances Medium distances and Long distances
What are the advantages of generating alternating Voltage for transmission?
The main advantage is that it's very easy to step alternating current up or down in voltage by the use of a transformer. High voltage is preferred for long distance transmission because it cuts transmission loss.
Why are skateboards good for long distances?
They aren't. Bikes are more suitable for long distances.
Do you say large distances or long distances?
Either is correct.
Which part of the neuron can carry information for long distances?
The axon is the part of the neuron that can carry information for long distances.
