Explanation

Thick strokes are never written upward in shorthand writing.

This ensures clarity and consistency.

As upward strokes are typically lighter for ease of writing.

Explanation

 Both Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) cables use twisted pairs of copper wires to transmit data.

The primary difference is that STP cables have additional shielding around the wires to protect against electromagnetic interference

Whereas UTP cables do not have this extra shielding

Explanation

USB 3.0 is a high-speed connection standard that can transfer data at speeds of up to 5 Gbps (gigabits per second), making it ideal for high data transfer.

Explanation

A Business Intelligence (BI) reporting system is designed to extract, transform, and present data in a format that supports business decision-making. BI systems typically provide features for:

• Filtering data (selecting specific data based on criteria)
• Grouping data (organizing data into categories or aggregations)

BI systems are not designed to modify the underlying data itself.

Explanation

• Data mining refers to the process of automatically discovering patterns, relationships, and insights from large datasets, using various machine learning and statistical techniques.
• It involves analyzing and extracting valuable knowledge or patterns from large databases, which can be used to make informed decisions or predictions.

Explanation

The main electronic component used in first-generation counterparts was Vacuum Tubes and Valves.

Leo is called the first-generation computer.

The five generations of computers:

1. First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC).
2. Second Generation (1959-1965 or 1956-1963): Transistor-based technology.
3. Third Generation (1965-1971 or 1964-1971): Integrated circuit-based technology.
4. Fourth Generation (1972-1980): VLSI microprocessor-based technology.
5. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.

Explanation

MAN stands for Metropolitan Area Network.

Explanation

The data dictionary is a part of a DBMS that stores metadata — details like table names, field names, data types, constraints, and relationships.

It helps the system manage and understand the structure of the database.

Explanation

A primary key must be unique for each record and never change.

Zip code is not unique (many people can share the same zip code), so it's not suitable as a primary key.
