Answer:

True

Explanation:

A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.

Generally, a computer is composed of five (5) main components and these include;

I. Input unit.

II. Output unit.

III. Central processing unit (CPU).

IV. Storage (memory) unit.

V. Power supply unit (PSU).

A power supply also referred to as power supply unit (PSU) can be defined as a hardware component of a computer that converts and step-down the domestic alternating current (AC) electrical power to a low-voltage regulated direct current (DC) power, so that the internal components of a computer can be supplied with power.

Hence, the power supply unit (PSU) serves as a rectifier by converting alternating current (AC) house current to direct current (DC) and as a transformer to step-down voltage from 220 Volts or 110 Volts to 50, 30, or 20 Volts depending on the requirements of a computer.

What is not an advantage of a computer network?
Nutka1998 [239]

Answer:

C. Social Engineering

Explanation:

Social engineering can be defined as an art of manipulating people, especially the vulnerable to divulge confidential information or performing actions that compromises their security.

Basically, it is a manipulative strategy or technique that involves the use of deceptive and malicious activities on unsuspecting victims in order to gain unauthorized access to their confidential or private information for fraud-related purposes. Some examples of social engineering attacks include quid pro quo, spear phishing, baiting, tailgating, water-holing, vishing, pretexting, phishing, etc.

Phishing is an attempt to obtain sensitive information such as usernames, passwords and credit card details or bank account details by disguising oneself as a trustworthy entity in an electronic communication usually over the internet.

Furthermore, phishing is a type of fraudulent or social engineering attack used to lure unsuspecting individuals to click on a link that looks like that of a genuine website and then taken to a fraudulent web site which asks for personal information.

In conclusion, social engineering being a form of cyber attack is not an advantage of a computer network.
