What is USB 2.0
Which organization developed the DisplayPort standard?
What is VESA
Which HDMI cable rating is required for 4K resolution and refresh rates over 60 Hz?
What is High Speed (Category 2)
Which of these cables was invented by Intel?
What is Thunderbolt
Which type of cable would you use to provide a power connection from an older Molex connector to a modern SATA drive?
What is A) Molex to SATA connector
Which type of USB connector is most commonly found on older digital cameras?
What is Mini-USB
Which of the following is a primary advantage of DisplayPort over HDMI?
What is Ability to daisy-chain multiple monitors
What is the maximum data transfer rate supported by Ultra High Speed HDMI cables?
What is 48 Gbps
Which peripheral connector serves as a display interface and a peripheral interface (like USB) and is primarily used on Apple workstations and laptops?
What is Thunderbolt
Your company wants to buy Android-based tablets to collect data for their sales force. Their tablets need a high-speed connection to transfer data at least 5 Gbps. Which cabling solution do you suggest for the equipment?
What is Use a USB 3.0 Micro connection.
What type of connector is defined by USB 3.1 and is often found on modern smartphones and laptops?
USB Type-C
What type of DisplayPort connectors are available?
What is Full-size DP++ and MiniDP/mDP
Which HDMI version introduced Premium High Speed cable ratings?
What is Version 2.0
The Serial Advanced Technology Attachment (SATA) replaced which of these technologies?
What is PATA
What is the main advantage of Serial ATA (SATA) over Parallel ATA (PATA)?
A) Higher data transfer rates
B) Lower power consumption
C) Backward compatibility with older drives
D) Smaller connector size
Higher data transfer rates
Explanation: Serial ATA (SATA) offers significantly higher data transfer rates compared to Parallel ATA (PATA), which is one of the primary reasons it replaced PATA in modern computer systems. SATA also has a more efficient data transfer process and smaller, more flexible cables.
Which type of USB connector is typically used on larger devices like printers?
What is USB Type-B
Why was DisplayPort developed as a royalty-free standard?
What is To reduce costs for PC graphics manufacturers
Which of the following HDMI versions supports 4K resolution at 120 Hz?
What is HDMI 2.1
Which of these is a reversible connector used on Apple products?
What is Lightning
Which of the following connectors is most commonly used to connect external hard drives for fast data transfer?
What is eSATA
Describe the key differences between USB 3.0 and USB 2.0 in terms of data transfer rates and connector types.
USB 3.0 supports data transfer rates up to 5 Gbps, significantly higher than USB 2.0's 480 Mbps. USB 3.0 connectors often have blue coloring and additional pins for higher data transfer, while USB 2.0 connectors are typically black or white.
Explain how DisplayPort supports multiple monitors from a single video source
DisplayPort supports daisy-chaining, allowing multiple monitors to be connected in a series to a single DisplayPort output on a video card. This is done by using DisplayPort’s multi-stream transport (MST) technology.
Explain the difference between HDMI 2.0 and HDMI 2.1 in terms of supported resolutions and data rates.
HDMI 2.0 supports up to 4K resolution at 60 Hz with a data rate of up to 18 Gbps. HDMI 2.1 increases this to support up to 10K resolution at 120 Hz and a data rate of up to 48 Gbps, enabling higher resolutions and refresh rates.
Describe the role of the Molex connector in legacy systems and its relevance today.
The Molex connector, with its 4 pins and red, yellow, and black wires, was used to provide power to older internal devices such as hard drives and optical drives. While still present in some systems, it has largely been replaced by SATA power connectors in modern devices.
Explain the differences between SATA and eSATA in terms of their use cases and performance characteristics.
SATA (Serial ATA) is used primarily for internal connections within a computer, such as connecting hard drives and SSDs to the motherboard. eSATA (external SATA) is an extension of SATA designed for connecting external drives, providing faster data transfer speeds than USB 2.0 and eliminating the need for an enclosure for external drives.
