and Object-Oriented
Communication Devices - CORRECT ANSWER: Allow a computer to send and receive
data and from other computers.
Complier - CORRECT ANSWER: Translates source code into machine language. A
compiler checks source code for errors before translating it into object code. e.g. C, C++, C#, and Java programs
Computer Memory - CORRECT ANSWER: Stores ephemeral programs and data in use
temporarily for quick access and primarily store it in RAM (Random Access Memory)

Control Unit - CORRECT ANSWER: It contains circuitry coordinating the machine's
activities
CPU (Contract Processing Unit) - CORRECT ANSWER: The CPU supports data
processing. The CPU is the electronic circuit responsible for executing computer program introductions.
Cyber Architect - CORRECT ANSWER: A person who is responsible for designing,
building, testing, and implementing security systems within an organization's information technology network. An individual within this position requires a thorough understanding of an organization's IT systems to anticipate possible network security breaches.
Cybersecurity Specialist - CORRECT ANSWER: Works with organizations to keep their information systems secure and ensure integrity, confidentiality, and availability of data.

methods to gain insights that support the organization's decision making.
Data Bus - CORRECT ANSWER: Carries data between the processor, the memory
unit, and the input/output devices.
Data Pyramid - CORRECT ANSWER: It is a concept that visualizes the data-
information-knowledge-wisdom hierarchy.
Database administration - CORRECT ANSWER: It refers to the whole set of activities that ensure all databases are highly available, secure, and scalable.
Database administrator - CORRECT ANSWER: A person who is responsible for
installing and configuring databases. This position also fixes database errors and creates user accounts.
Database Administrator (DBA) responsibilities - CORRECT ANSWER: Database
security, tuning, high availability, business continuity, backup & recovery, reporting, and designing & developing database applications.

Device Driver - CORRECT ANSWER: Software that facilitates the communication
between a device and the operating system.
Dictionary Attack - CORRECT ANSWER: Performed by the attacker by using an
application and a large dictionary text file with just words. When the attacker runs the application, it tries identifying the password by trying hundreds or thousands of words per minute from that dictionary file.
Distributed Systems - CORRECT ANSWER: Interactions between computers via
networks have become commonplace and multifaceted. Many modern systems, such as global information retrieval systems or computer games, are designed as distributed systems. Distributed systems execute software as processes on more than one computer.
DoS (denial of service) attack - CORRECT ANSWER: the process of overloading a
computer with messages and results in suffocating the network resources.
Expansion slots - CORRECT ANSWER: a place in a computer where an expansion
card can be inserted.
Fifth Generation Computer - CORRECT ANSWER: We will be using artificial
intelligence to predict our needs and programming systems that can learn.
