Part 1: Read the following passages and choose the correct answer Passage 1
The resistor is a fundamental electrical component in physical circuits as well as equivalent
circuits. It was the earliest electrical attribute - identified shortly after electrical current was
discovered. All materials exhibit some form of resistance, some are greater than others, eg. copper,
aluminum and gold have low resistance; carbon and tungsten have medium resistance, and then
ceramics, and air have high resistance. The earliest resistors were constructed from metal
substances although, in all fairness, carbon may well have been used in the first resistor
implementation. This substance formed the filament of the first early incandescent light bulb said
to have been invented by Thomas Edison recorded in the USA patent of 1879. Unlike metals,
carbon has a relatively high resistivity and can also be formed into thin films suitable for deposition
on an insulating material such as ceramic. Further, carbon particles can be mixed with insulating
materials (e.g. clay) to further increase its resistivity. Carbon composition resistors were
commonly used in the 1960s and earlier, but are not popular for general use now as other types
have better specifications, such as tolerance, voltage dependence, and stress. In 1960, Felix
Zandman and Sidney J. Stein presented a development of resistor film of very high stability. The
primary resistance element of a foil resistor is a chromium nickel alloy foil several micrometers
thick. Since their introduction in the 1960s, foil resistors have had the best precision and stability of any resistor available.

Telecommunication is defined as the science and technology of communication over a far
distance. The ability to transmit information quickly, accurately, and efficiently has always been
one of the main focuses driving human innovation. From prehistoric man with their fire signal to
the fifth- generation technology providing up to 10 gigabits per second, a never-ending
improvement in telecommunication can be seen together with the advancement of modern
civilization. Here are some take-aways about the electronic telecommunication history. In 1838,
Samuel B. Morse could send a message by letting electricity run through a wire and holding or
releasing a button, which is called telegraph. In 1876, Alexander Graham Bell discovered how to
transmit speech electrically, and then invented the telephone. In 1893, radio wave was successfully
transmitted for the first time. In 1915, the first long- distance call (coast to coast call) was made
by Alexander Graham Bell and his assistants, making long- distance communication over the
country become real. Together with the conventional telecommunication services based on the
telephone and telegraph systems, data and video communication are being installed and operated
thanks to Pulse Code Modulation (PCM) method, providing that digital transmission is not only
more economical but also more reliable than its counterpart, analog transmission.

Face recognition systems can be used to identify people in photos, video, or in real-time. Face
recognition systems use computer algorithms to pick out specific, distinctive details about a
person’s face. These details, such as distance between the eyes or shape of the chin, are then
converted into a mathematical representation and compared to data on other faces collected in a
face recognition database. Face recognition systems vary in their ability to identify people under
challenging conditions such as poor lighting, low quality image resolution, and suboptimal angle of view.
When it comes to errors, there are two key concepts to understand:
(1) A “false negative” is when the face recognition system fails to match a person’s face to an
image that is, in fact, contained in a database. In other words, the system will erroneously return
an unknown identity in response to a query.
(2) A “false positive” is when the face recognition system does match a person’s face to an image
in a database, but that match is actually incorrect. This is when a police officer submits an image
of “Mai,” but the system erroneously tells the officer that the photo is of “Thảo.”
When researching a face recognition system, it is important to look closely at the “false positive”
rate and the “false negative” rate, since there is almost always a trade-off. For example, if you are
using face recognition to unlock your phone, it is better if the system fails to identify you a few
times (false negative) than it is for the system to misidentify other people as you and to let those
people unlock your phone (false positive).
One of the benefits of facial recognition systems centers on its application in biometrics. It can be
used as a part of identification and access control systems in organizations, as well as personal
devices. The system can also be used to enable automated image recognition capabilities. Through
machine learning and Big Data analytics, social networking sites such as Facebook can recognize
photos of its users and allow automated linking or tagging to individual user profiles. Another
advantage of facial recognition systems involves its application in law enforcement and security
systems. However, facial recognition systems are less reliable and efficient than other biometric
systems such as fingerprints. Factors such as illumination, expression, and image or video quality,
as well as software and hardware capabilities, can affect the performance of the system.
