Wats the difference between a slot port and a square port. Cant seem to find the answer anywhere. Quote; Alpine CDA-9886. SoundStream PCA2000D. The Accelerates Graphics Port is a high-speed point-to-point channel for attaching a video card to a computer's motherboard. It was created in 1997 yet by 2004 was largely replaced by PCI Express. The primary advantage of AGP over PCI is that it provides a dedicated pathway between the slot and the processor rather than sharing the PCI bus. Slots refer to connectors on a circuit board where auxiliary circuit boards can be plugged in. They are usually much longer than they are wide, and have a gap (i.e. Slot) running along the length. In software, ports are numbers used to identify the type of internet communication and the program that is designed to process that type. A PCIe x16 slot, for instance, will have 16 lanes of bandwidth to use when communicating with the rest of the system, which makes it ideal for graphics cards and low-latency expansion. What's the difference between PCI Express standards? The main difference between PCI Express standards is speed and bandwidth.

This board contains a port and fits into a slot.

Slots and ports are physical connection points that allow the hardware of a computer to be expanded. A port is a socket. A slot is a dock for a printed circuit board.


Features


Slots are also called 'expansion slots' because they allow the computer to be expanded. The circuit board that fits into the slot is also called Casino albion road ottawa. a 'card.' At the back of a desktop computer, you will see a number of blocked letterbox-shaped openings. These show where the slots are on your computer. Cards that include ports need to protrude through the case of the computer so that users can connect peripherals.


Function


A card may include ports, although it does not have to. A sound card might just enhance the existing functions of a computer, in which case it would not need ports. If it controls speakers and microphones, it will have ports and sockets that need to be accessed by the user.


Advantages

Expansion

Slots and ports enable owners to upgrade their computers. Ports are the easiest to use. You might have an external drive connected to a port on your computer. When you want to upgrade this device, you only need to unplug it and plug in the new external drive.

PC Card Slot Types

  • ISA
  • AGP
  • PCI
  • PCI-X
  • PCI-E (PCIexpress)

ISA

Difference

ISA, or Industry Standard Architecture, is an 8bit or 16bit parallel bus system that allowed up to 6 devices to be connected to a PC. Virtually all IBM-compatible PCs made before the Pentium were based on the ISA (IBM's PC AT) bus. This asynchronous bus architecture uses 16-bit addresses and an 8-MHz clock and handles a maximum data throughput of 2 MB/s to 3 MB/s.

ISA is the precursor to PCI. Standing for 'Industry Standard Architecture' It was common from the early 1980s to the mid 1990s. ISA was a typically inelegant solution for the time, and required one to know exactly what one was doing- PnP was rare, even for so called 'ISA PnP' peripherals. In the end, the combination of flexibility, ease of use, and greater capability allowed PCI to supersede ISA.

PCI

Difference Between Expansion Slots And Ports

The PCI bus architecture is a processor-independent bus specification that allows peripherals to access system memory directly without using the CPU. Not only does this free up the CPU to service other application calls, but PCI users also can simultaneously acquire data to memory and analyze existing data in real time, all while communicating with other functions on the network.

More importantly, PCI peripherals running asynchronously can send data along the 32-bit bus at a rate of up to 132 MB/s or 66 MS/s.

AGP

2019

The Accelerates Graphics Port is a high-speed point-to-point channel for attaching a video card to a computer's motherboard. It was created in 1997 yet by 2004 was largely replaced by PCI Express. The primary advantage of AGP over PCI is that it provides a dedicated pathway between the slot and the processor rather than sharing the PCI bus. In addition to a lack of contention for the bus, the point-to-point connection allows for higher clock speeds. AGP also uses sideband addressing, meaning that the address and data buses are separated so the entire packet does not need to be read to get addressing information. This is done by adding eight extra 8-bit buses which allow the graphics controller to issue new AGP requests and commands at the same time with other AGP data flowing via the main 32 address/data (AD) lines. This results in improved overall AGP data throughput.

PCI-X

PCI-X stands for 'PCI-eXtended'. PCI-X is a computer bus and expansion card standard that enhances the 32-bit PCI Local Bus for higher bandwidth demanded by servers. It is a double-wide version of PCI, running at up to four times the clock speed, but is otherwise similar in electrical implementation and uses the same protocol.[1] It has itself been replaced in modern designs by the similar-sounding PCI Express, which features a very different logical design, most notably being a 'narrow but fast' serial connection instead of a 'wide but slow' parallel connection.

Difference Between Expansion Slots And Ports List

PCI-X revised the conventional PCI standard by doubling the maximum clock speed (from 66 MHz to 133 MHz)[1] and hence the amount of data exchanged between the computer processor and peripherals. Conventional PCI supports up to 64 bits at 66 MHz (though anything above 32 bits at 33 MHz is only seen in high-end systems) and additional bus standards move 32 bits at 66 MHz or 64 bits at 33 MHz. The theoretical maximum amount of data exchanged between the processor and peripherals with PCI-X is 1.06 GB/s, compared to 133 MB/s with standard PCI. PCI-X also improves the fault tolerance of PCI allowing, for example, faulty cards to be reinitialized or taken offline.

PCI Express

PCIe, or Peripheral Component Interconnect Express, is a computer expansion card standard designed to replace the older PCI, PCI-X, and AGP standards. PCI Express is used in consumer, server, and industrial applications, as a motherboard-level interconnect (to link motherboard-mounted peripherals) and as an expansion card interface for add-in boards. A key difference between PCIe and earlier buses is a topology based on point-to-point serial links, rather than a shared parallel bus architecture.

* Note - Since PCI Express is a serial based technology, data can be sent over the bus in two directions at once. Normal PCI is Parallel, and as such all data goes in one direction around the loop.
