    1.. Point out the different types of video connectors.

    Explain their differences, add an image and


    number of pins for each one.

    -VGA video cable: It is the 15-pin video connector that only transmits
    image signal up to 30 m away, but cannot audio. Originally, the
    maximum resolution supported by a VGA cable was 640x480 pixels.
    Nowadays, taking into account the factors that influence image quality
    and technological advances, for theoretical purposes it would be a
    maximum resolution of 2048x1536 pixels at 85 Hz. Of course, with a
    good thick shielded coaxial cable and a short length to avoid image
    degradation. With a normal, well-shielded 2 m cable and ferrite cores, the resolutions it can transmit
    are 1920x1080.

    -DVI video cable:DVI cables transmit the image pixel by


    pixel. This means that there is never image deterioration for a
    given resolution and maximum cable length. For example, a
    cable with a maximum length of 15 m can transmit 720p
    resolutions without deterioration. For 1080p images the
    maximum length would be 4.5 m.

    DVI-A: They have 12 pins on the main block and 5 on the analog part. It only transmits high
    resolution analog signal. It is the most basic and very similar to VGA. It is used if you are going to
    connect a computer with DVI output to a monitor with VGA input. It is the most economical.

    DVI-I: It is universal, since it transmits in analog and digital. Which gives it greater versatility of
    use. It has the SL option (single link, that is, simple link) with 18 pins in the digital part and 5 in the
    analog part. And the DL option (dual link, that is, double link) with 24 pins in the digital part and 5
    in the analog part.

    If you want to combine analog and digital inputs or outputs, as analog and digital formats are not
    interchangeable, you will need an electronic converter from analog to digital or vice versa,
    depending on the use case.

    DVI-D: Only transmits in digital. It is arguably the first digital-only video cable. Provides higher
    image quality and higher transmission speed. It also has the SL version (with 18+1 pins) and DL
    (with 24+1 pins). Its use is between digital video outputs and digital video inputs on LCD motors or
    higher.

    Cable de vídeo HDMI

    HDMI 1.0: Maximum resolution of 1080p at 60 Hz, 8 channels of 24-bit audio and a maximum
    transfer rate of 4.9 Gbits/s.
    • HDMI 1.1: Same as HDMI 1.0 including support for DVD audio.
    • HDMI 1.2: Included 720p resolutions at 100 Hz and 120 Hz, as well as adding support for high
    fidelity audio.
    • HDMI 1.3: Maximum resolutions of 2560x1440 at 60Hz,
    Dolby TrueHD and DTS-HD Master Audio audio formats,
    inclusion of the mini HDMI connector type and transfer rate of
    10.2 Gbits/s. Use is perfect for BlueRay devices and consoles.
    • HDMI 1.4: Maximum resolution 4k (4096x2160 pixels) at 24
    Hz and 3840x2160 at 30 Hz. Possibility of sending 3D video.
    Inclusion of micro HDMI connector type. And the possibility of
    sending and receiving data as an Ethernet connection at a
    maximum speed of 100 Mbits/s.
    • HDMI 2.0: 4K resolution at 60 Hz, 32 audio channels, 2 video streaming for the same screen, 4
    audio streaming, streaming audio and video synchronization and support for dynamic HDR.
    • HDMI 2.1: 8K and 4K resolution at 120 Hz with 48 Gbits/s bandwidth.

    Cable de vídeo DisplayPort


    -Obviously, they are not immune from being
    affected by the length of the cable in signal
    degradation. For DP cables the maximum
    length is 5 m. Although for lossless Full HD
    qualities they can reach 15 m.

    DisplayPort 1.0: 1440p resolution at 60 Hz with 6.4 Gbits/s bandwidth.


    DisplayPort 1.1: 4K resolution at 30 Hz, 8 audio channels and 10.8 Gbits/s bandwidth.
    DisplayPort 1.2: 8K resolution at 30 Hz, 8 audio channels and 21.6 Gbits/s bandwidth. It also
    allowed Multi Stream Transport daisy chain connection with which video can be transmitted
    independently between different monitors. 4 screens with the same cable, simultaneously, at
    1920x1200 pixel resolution. Or 2 screens at the same time with resolution 2560x1600 pixels.
    DisplayPort 1.3: Resolution 8K at 30 Hz, 5K at 60 Hz, 4K at 120 Hz, bandwidth 32.4 Gbits/s. In
    addition to MST technology with which you can watch 4K video at 60 Hz on two screens at the
    same time.
    DisplayPort 1.4: 8K resolution at 60 Hz and 32.4 Gbits/s bandwidth.
    DisplayPort 2.0: Expected to appear at the end of 2020 with 16K resolution at 60 Hz and 77.4
    Gbits/s bandwidth on a single cable.

    Types of Hard Drives:

    1. HDD Hard Drives (Hard Disk Drive):


    - Description: They store data on rotating magnetic disks.

    - Pros:
    - Greater storage capacity.
    - Cheaper per gigabyte.
    - Cons:
    - Lower reading and writing speed compared to other types.
    - More prone to mechanical failure.
    2. SSD Hard Drives (Solid State Drive):
    - Description:They use flash memory for storage.

    - Pros:
    - Higher reading and writing speed.
    - Less prone to physical damage.
    - Cons:
    - More expensive per gigabyte.
    - Storage capacity generally smaller than HDDs.

    3. SSHD Hybrid Drives (Solid State Hybrid Drive):


    - Description: They combine the storage capacity of HDD with the speed of SSD.

    - Pros:
    - They offer a balance between capacity and performance.
    - Cons:
    - Lower performance than a pure SSD.

    Hard Drive Connectors:

    1. SATA (Serial ATA) Connectors:


    - Description: Used to connect hard drives and SSDs to the
    motherboard.
    - Pins: SATA connectors usually have 7 pins.

    2. SATA Express Connectors:

    - Description: Advanced version of SATA, allows higher speeds.


    - Pins: Combines traditional SATA and PCI Express connectors.

    3. M.2 Connectors:

    - Description:Compact and mainly used for SSDs.


    - Pins:Vary depending on type (for example, M key or B key).

    4. IDE (Integrated Drive Electronics) Connectors:

    - Description: Old, mainly used by older HDD hard drives.


    - Pins: 40 or 80 pin connectors, depending on the type.
