Difference Slot Port

A slot port vs sqaure port is the same thing, the only difference is the slot is Square ( all sides being equal ) vs slot rectangle ( unequal ) plus it has nothing to do with whether the walls of the enclosure are or are not used. Slot port is easier to build. Slot port adds strength. Slot port has a higher tendancy for turbulence since it uses 90degree corners. Slot port is cheaper. Round port if flared are more efficient. Round port costs more to make. Round ports are a bitch sometimes to mount, as they need support internally so they dont move. Round ports are not the same as aeroports. If you’re looking to use the features of HDMI 2.1, for example, you need a monitor with an HDMI 2.1 port and a video card with an HDMI 2.1 port—if one of them is running HDMI 2.0, you won’t. In this video I discuss the difference between an M.2 SSD and a NVME PCI-Ex4 SSD. From how to tell them apart just by looking at them and little bit about r. Available PCI Express lanes are often distributed across two slots, meaning that the second PCIe port may only run eight lanes electrically. This also means that the speed of one physical x16 PCIe.

HDMI vs Mini HDMI

The basic difference between HDMI and Mini HDMI, as the names suggest, is the size; however, there are also other differences, which are addressed in this article. HDMI and mini HDMI are two port sizes that come under the HDMI standard. HDMI is the large sized slot used on devices such as monitors, projectors and graphics cards while mini HDMI is the smaller version of HDMI that is found on small devices such as digital camera, camcorders, and DSLRs. The number of pins is the same despite the difference in sizes, but the order of what pins are assigned have been changed. Other details such as voltages, speeds, bit rates, and protocols remain the same in both interfaces. It is important to note that there is a further smaller interface size known as micro HDMI used for devices like phones and it is NOT the same as mini HDMI.

What is HDMI?

HDMI, which stands for High Definition Multimedia Interface, is an interface used to transmit multimedia. It can transmit both audio and video in digital format where the video stream is uncompressed and audio stream can be compressed or uncompressed. There are several types of HDMI ports that differ in size under names type A, type B, type C and type D.

In general language, what HDMI refers is to the HDMItype A interface. This port has dimensions of 13.9 mm × 4.45 mm. This port has a number of 19 pins. HDMI carries out differential transmission and, therefore, to transmit one data bit there should be a pair of wires. In HDMI, there are 3 data lines as Data 0, Data 1 and Data 2. Data 0+, Data 1+ and Data 2+ are connected to pin numbers 7, 4 and 1 respectively and Data 0-, Data 1- and Data 2- are connected to pins 9, 6 and 3 respectively. Pin 8, 5 and 2 are connected to the shield for Data 0, Data 1 and Data 2. Pin 10,11 and 12 are used for the clock and they are respectively used for Clock+, Clock shield and Clock-. Pin number 13 is used for CEC (Consumer Electronics Control), which is a feature used to send user commands to control HDMI devices. Pin 14 is reserved and will be used in future standards. Pins 15 and 16 are used for something called DDC (Display Data Channel) and pin 17 is a shield for the CEC and DDC channels. Pin 18 is the power supply, which is connected to +5v to allow a maximum of 50 milliamperes. Pin 19 is the Hot Plug Detect, which is responsible for detecting connection and disconnection of devices while turned on.

HDMI type A port is usually found on comparatively larger devices such as Monitors and projectors. What is found on computers graphics cards as well is HDMI type A slots.

What is Mini HDMI?

Mini HDMI refers to the HDMItype C interface. This connector is much smaller than HDMI type A interface. The dimensions are 10.42 mm × 2.42 mm. However, the special thing is that it has the same number of pins that is 19. The order of the pins is bit different with what is found on type A. Positive signal pins have been swapped with the corresponding shields. That is pins 1, 4 and 7 have been swapped with pins 2,5 and 8. Shield for the CEC and DDC channels is connected to pin 13 instead of pin 17. CEC (Consumer Electronics Control) is connected to pin 14 instead of pin 13. The reserved pin here is pin number 17.

The speed, bit rate and the protocol are exactly similar to the HDMI type A. Because of the small size this is used in comparatively smaller devices such as Digital cameras, camcorders, DSLR where space is not enough to accommodate a full HDMI port.

A device with a mini HDMI interface can be connected with any device with a full HDMI interface without any issue. For example, a camcorder with a mini HDMI output can be connected to a monitor with an HDMI input using a HDMI cable whose one side is mini HDMI and the other side is HDMI.

What is the difference between HDMI and Mini HDMI?

• HDMI refers to the HDMI receptive of type A and mini HDMI refers to HDMI receptacle of type C.

• HDMI has a port size of 13.9 mm × 4.45 mm while the size of mini HDMI is 10.42 mm × 2.42 mm. So, the size of mini HDMI is much smaller than HDMI.

• Positive signal pins used in HDMI are 7, 4 and 1 and the respective pins for shield are 8, 5 and 2. However, in mini HDMI these are swapped. 7, 4 and 1 are used for the shield while 8, 5 and 2 are used for positive data.

• Shield for the CEC and DDC on HDMI is connected to pin 17. However, on mini HDMI this is connected to pin 13.

• CEC (Consumer Electronics Control) is connected to pin 13 on HDMI while this is connected to 14 on mini HDMI.

• Pin 14 on HDMI is reserved while on mini HDMI it is the pin 17 that is reserved.

• HDMI is used in larger devices such as monitors, projectors and graphics cards while mini HDMI is used in relatively small devices such as digital camera, camcorders and DSLRs.

Summary:

Mini HDMI vs HDMI

The major difference between HDMI and Mini HDMI is in the sizes. HDMI is the larger version and mini HDMI is the smaller version. The number of pins is the same, but there are differences in what each pin is assigned to. Despite the size and the difference in pin assignment there are no other changes. Both are used for transmitting multimedia including video and audio. HDMI most precisely known as type A HDMI is found on large devices while mini HDMI known as type C is found on small devices that cannot accommodate the space for a type A HDMI.

Plug

The plug is part of a cable that connects to a port. The plug always connects to something else (e.g., a jack or port). For example, the most common plug is the power plug that connects your computer, monitor, and other devices to a power source. The picture is a U.S. desktop power cord with a male plug end that connects to the wall socket and female plug end for the computer or monitor.

In our example of a power cord plug, this plug is different in different countries around the world.

Cable and cord

A cable or cord is one or more wires in a plastic covering that allows for the transmission of power or data between devices. The picture is an example of a Cat 5 network cable. See our cable definition for a list of types of cables used with computers.

Wire

A wire is a single strand of metal (e.g., copper) or optical fibers capable of transmitting power or data from one area to another.

Connector

Difference Slot Portugal

A connector is the unique end of a plug, jack, or the edge of a card that connects to a port. For example, all desktop computer expansion cards have a connector that allows them to connect in a slot on the motherboard. When referring to cables, the connector is the end of the cable that connects into a port. For example, the end of a USB cable has a connector that allows it to connect to a USB port.

Port

The port has either holes or a slot that matches the plug or card connected to the port. The picture is a computer PS/2 port for a keyboard and mouse with a PS/2 connector to connect to the computer.

There are also software ports. For example, port 80 is a network port that allows HTTP traffic on a network.

• See our port definition for a full listing of computer ports.

Jack

A jack is similar to a port and is a hole or other connection that allows a compatible plug to connect to the jack. With computers, a jack often describe an audio jack.

Adapter

An adapter is a device capable of converting power or data from one source of input into another. For example, an AC adapter used with laptop computers and other devices takes AC power and converts it into DC power.

Socket

A socket is an opening that fits another specific device with matching pins or other connectors. A socket example is a CPU socket, which is a socket on the motherboard for a computer CPU.

Over the evolution of computers, there were many different sockets designed for computers. Each socket supports a set of computer processors. For example, the Socket 370 is a socket that supported the first Intel Celeron processors and Coppermine processors.

Slot

A slot is also a connection used with computers that either describes a CPU slot or an expansion slot. Today, CPU sockets are used instead of CPU slots, but expansion slots still connect expansion cards to the computer.
