Straight Through Cables vs Crossover Cables: Key Difference

-

What is an Ethernet cable?

An Ethernet cable is a network cable used for high-speed wired network connections between two devices. This network cable is made of four-pair cable, which is consists of twisted pair conductors. It is used for data transmission at both ends of the cable, which is called RJ45 connector.

The Ethernet cables are categorized as Cat 5, Cat 5e, Cat 6, and UTP cable. Cat 5 cable can support a 10/100 Mbps Ethernet network while Cat 5e and Cat 6 cable to support Ethernet

 What is Straight Through Cable?

Straight Through Cable

Straight-through cable is a type of CAT5 with RJ-45 connectors at each end, and each has the same pin out. It is in accordance with either the T568A or T568B standards. It uses the same color code throughout the LAN for consistency. This type of twisted-pair cable is used in LAN to connect a computer or a network hub such as a router. It is one of the most common types of network cable.

What Is Crossover Cable?

Crossover Cable

When to use Crossover Cable?

A Crossover cable is a type of CAT 5 where one end isT568A configuration and the other end as T568BConfiguration. In this type of cable connection, Pin 1 is crossed with Pin 3, and Pin 2 is crossed with Pin 6.

Crossover cable is used to connect two or more computing devices. The internal wiring of crossover cables reverses the transmission and receive signals. It is widely used to connect two devices of the same type: e.g., two computers or two switches to each other.

In regard to physical appearance, Crossover Ethernet cables are very much similar to regular Ethernet cables. Still, they are different with regard to the order with which the wires are arranged. This type of Ethernet cable is made to connect to network devices of the same kind over Ethernet directly. Crossover cables are mostly used to connect two hosts directly.

KEY DIFFERENCES:

  • Crossover cable, Pin 1 is crossed with Pin 3, and Pin 2 is crossed with Pin 6 while in Straight-through cable Pin connection is one to one.
  • Straight-through cables are mainly used for connecting non-similar devices while crossover cables are mostly used for connecting similar devices.
  • Straight through cable connects a computer with a DSL modem while Crossover cable connects Router to Router and Computer to Computer.

 

When to use Straight Through Cable?

Computer to network switch/hub

Here are applications where you should use Crossover Cable:

  • It helps you to connect a computer to a switch/hub’s normal port.
  • You can use it to connect a computer to a cable/DSL modem’s LAN port.
  • It allows you to connect a router’s WAN port to a cable/DSL modem’s LAN port.
  • Connect 2 switches or hubs with one of the hub or switch using an upline port and the other one using a normal port.
 
Use of Cross over cable- computer to computer

Router to Router

Here is an application where you should use Crossover Cable:

  • It can use a computer to a computer with no switch or hub.
  • Network devise to the network device. For example, the route to the router.
  • Crossover cable enables one to establish a direct connection between two computing devices using Ethernet ports.
  • It Connects two computers directly.
  • You can connect two hubs/switches by using the normal port in both switches and hubs.

Difference between Crossover and Straight-through cable

Here are the difference between Crossover and straight-through cable

Straight through Crossover
Straight-through cable is a type of CAT5 with RJ-45 connectors at each end, and each has the same pin out. A Crossover cable is a type of CAT where one end is T568A configuration, and the other end as T568B Configuration.
It is one of the most commonly used cable formats for network cables. It is used only for certain applications.
You can also connect it to the router’s LAN port to a switch/hub’s uplink port. You can connect it to a router’s LAN port to a switch or hub’s regular port
Straight through cable connects a computer with a cable or DSL modem’s LAN port. Crossover cable connects with a router’s LAN port with switch/hub normal port.
You should use straight-through cable when you want to connect two devices of different types. You should use a crossover cable when you want to connect two devices of the same type.
It helps you connect a router’s WAN port to a cable or DSL modem’s LAN port. You can connect two switches/hubs by using the normal port in both switches/hubs.
Straight-through cables are mainly used for connecting, unlike devices. While crossover cables are mostly used for connecting like devices.

Straight Through vs. Crossover Cable, which one to choose?

The selection or network cable should be done based on your application. If you want your cable to connect to your computer and printer together, you need a crossover cable. If you have several computers and a printer, you should buy a switch.

All the computers connected to the switch with a straight–through cable and printer should be connected to the switch with a straight-through cable.

 If you are having an issue with installing a printer or getting other issues dealing with a printer or printer setup on the computer, try this troubleshooter.  If a step doesn't apply, skip to next step  1. Turn computer off  2. Turn printer off 3. Disconnect power to printer for 2 minutes  4. Turn printer back on  5. Wait one minute  6. Make sure all connections are good  7. If your printer has both parallel and USB connectors, only have one of the two connected and not both. The USB is faster. (most new systems do not have parallel connections)  8. Turn computer back on  9. Make sure the printer has ink  10. Is the printer networked? If so is it connected to the network via computer or router. If it is connected via a computer and the computer is off, the other systems will not see it.  11. Make sure the dependencies to the print spool is started  12. Check the manufacturer of the printer to see if there is a newer driver for the printer.  13. Check the manufacturer for any patc

RESISTOR TESTING

1- Visual inspection: Checks for missing or any burning on resistance.   2- Using Digital Multimeter: You can check the resistor resistance by selecting the ohm range in the digital multimeter, If the resistor is in circuit, you will generally have to remove the resistor so you are testing only the resistor value and not the other components in the circuit.   Connect test probes across the two points of the resistor as shown in the photo, polarity isn’t important, value of resistance shown is 9.86 kΩ. Note: All resistors have a specific tolerance rating. The tolerance rating is marked by a color band on the end of the resistor’s body, normally the band is gold indicating 5 % tolerance. If the tolerance band is silver, then the rating is 10 %. How to test SMD Resistors: Because of the small size of SMD resistors, there is often not room for the traditional color band code to be printed on them. Therefore, new resistor SMD codes were developed. The most commonly seen codes are the three

IP Address: internet protocol

-
   What is an IP address?     An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.     It serves two main functions: identifying the host or network interface and providing the location of the device in the network. Types of IP addresses:     IPv4: This is the most common type of IP address used today. It consists of four sets of numbers separated by periods (e.g., 192.168.0.1). IPv4 allows for approximately 4.3 billion unique addresses.     IPv6: With the increasing number of connected devices, IPv6 was introduced to address the depletion of IPv4 addresses. It uses eight sets of numbers separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 provides a significantly larger address space. How IP addresses work:     When a device wants to communicate with another device over the internet, it needs to know the destination device's IP ad
