Difference Between Ports And Slots

broken image


In Gigabit Ethernet applications, either SFP port, RJ45 port or GBIC port is used in different Gigabit devices, such as switches, routers, servers and storages. And some latest wireless access points (APs) are also equipped with SFP port. Since all these three port types only support 1Gbit and do not go any higher, why are they created instead of using only one type?

In this part, I will explain PCI vs PCI Express from 3 aspects. Read on to learn about differences between PCI and PCIe further. PCI vs PCIe Slot. In this part, I will show you what PCI and PCIe slots look like. The first one I will introduce is PCI slot. This slot has two types: 32-bit slot with 124 pins and 64-bit slot with 188 pins. In some aircraft, the slats are fixed, which opens up a slot between the wing and the slat. In this case, the terms slot and slat are used interchangeably. 'Leading edge slot' by Sanchom - Own work.

SFP Port vs. GBIC Port: An Improvement in Dimension

Ports

SFP port and GBIC port can be found in a variety of equipment, including Ethernet switches, routers, network interface cards, servers, etc. Today most Ethernet switches are designed with as least one or two Gigabit SFP uplink slots. What is SFP port? As the name implies, SFP port is intended for taking in SFP (mini-GBIC) fiber modules with small form-factor (SFF) connectors, while GBIC port is for accepting GBIC modules.

The two types of ports can provide the same data rates and same distances in Gigabit applications, but the same number of SFP ports uses less space than that of GBIC ports. Since they have the equal functionality, SFP has gradually taken the place of the older GBIC in Gigabit networking for space-saving and economical reasons. The table below is a comparison of SFP port vs. GBIC port.

SFP vs. RJ45 port: Distance Makes Difference

The RJ45 ports in Gigabit networking devices follow the 1000BASE-T Ethernet standard. They only support twisted pairs for network connections, and the distance is limited to 100 m (330 feet). Poker bad blue line. RJ45 port uses Category 5/5e/6 and higher level copper Ethernet cables for 1Gbit transmission. Compared with switch using only RJ45 port, SFP port switch supports more types of communication cables and longer reaches of links. Here are the differences between SFP vs. Casino reims paix.

Since most end-points at the customer's are still using RJ45 port, in order to retaining the convenience of RJ45 port while providing the advantage of SFP network to customers, some switches include combo SFP/RJ45 ports. So users can choose to utilize either the SFP port or the RJ45 port at a time for short-distance connections.

What Is Dual-Rate SFP Port?

Unlike the combo SFP/RJ45 port which is actually a link shared by two different ports, a dual-rate SFP port is one single SFP slot that can be configured to support two different data rates. Generally a dual-rate SFP slot can set to be either 1G mode or 10G mode, i.e., an SFP module or an SFP+ module can be installed in it. But the actual data rate of the transmission depends on the mode being settled and the transceiver module being used. There are several cases:

  • The dual-rate SFP slot is 10G activated, and an SFP+ module is installed; the interface is in 10G mode.
  • The port is 10G activated, but an SFP module is installed; the interface is in 1G mode.
  • The port is not 10G activated, but an SFP+ module is installed; the interface will be link down state.
  • The port is not 10G activated, and an SFP module is installed; the interface is in 1G mode.

Summary

Difference

The three port types—SFP port, RJ45 port and GBIC port—are used in different networking equipment. The SFP port is now more commonly used than GBIC port since the former one provides the same function and is more compact. When SFP port vs. RJ45 port, SFP port supports connectivity through varieties of fiber cables and the copper twisted pairs, and a wide range of link distances, but RJ45 port accepts only twisted pair cables and a shorter distance. Since every thing has both two sides, it is not always the best to choose SFP slot.

Difference Between Ports And Slots

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 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.


Which Of These Best Describes The Difference Between Ports And Slots

Advantages


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.
