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

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.

Explanation

Bridges are used to connect similar LANs that use the same network protocols.

They help manage traffic and reduce collisions by dividing networks into segments.

Explanation

Beeps or failure to boot can indicate a hardware or firmware issue, which is typically reported by the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware during the boot process.

Explanation

• Adobe Photoshop is the most frequently used graphics software.
• Photoshop is the industry standard for raster graphics editing, used for photo editing, digital painting, and graphic design.
• Its versatility and wide range of features make it the go-to choice for professionals and hobbyists alike.
