WHAT IS STRAIGHT-THROUGH NETWORK CABLE?

  • Usually use straight cable to connect different type of devices.
  • If you need to check how straight cable looks like, it's easy. Both sides (side A and side B) of cable have wire arrangement with same color.

Image result for straight through cableIn straight cable connectivity is like as follows
RJ451 Connected to RJ452
Pin1------------------------------------- Pin1
Pin2------------------------------------- Pin2
Pin3------------------------------------- Pin3
Pin4------------------------------------- Pin4
Pin5------------------------------------- Pin5
Pin6------------------------------------- Pin6
Pin7------------------------------------- Pin7
Pin8------------------------------------- Pin8



This type of cable will be used most of the time and can be used to:
  1. Connect a computer to a switch/hub's normal port.
  2. Connect a computer to a cable/DSL modem's LAN port.
  3. Connect a router's WAN port to a cable/DSL modem's LAN port.
  4. Connect a router's LAN port to a switch/hub's uplink port. (Normally used for expanding network)
  5. Connect two switches/hubs with one of the switch/hub using an uplink port and the other one using normal port.


What is Cross-over Network Cable?

  • A crossover cable is a cable that is used to interconnect two computers by "crossing over" (reversing) their respective pin contacts.
  • Sometimes you will use crossover cable, it's usually used to connect same type of devices.
  • The reversing or swapping of cables varies, depending on the different network environments and devices in use. 
  • Examples of crossover cables are null modem cables, rollover cables and loopbacks.

A crossover cable can be used to:

  1. Connect two computers directly.
  2. Connect a router's LAN port to a switch/hub's normal port. (Normally used for expanding network)
  3. Connect two switches/hubs by using normal port in both switches/hubs.



In cross cable connectivity is like as follows:

      The speed of your internet still depends on your chosen network. (e.g Globe, PLDT etc.)

      No. The range of your internet only depends on the antenna of your modem.

    Are there techniques you can use in order to intact it together like the wanted order of wires inside the RJ45?

    What is the difference between a straight-through Ethernet cable, and a crossover Ethernet cable?

SERIES AND PARALLEL CIRCUIT

Image
SERIES AND PARALLEL CIRCUIT WHAT IS SERIES CIRCUIT? A series circuit is one that has more than one resistor, but only one path through which the electricity (electrons) flows. From one end of the cell (battery), the electrons move along one path with NO branches, through the resistors, to the other end of the cell. All the components in a series circuit are connected end-to-end. Resistor-   is anything that uses some of the power from the cell. Each time there is damage (break) in any one of the resistors the entire circuit will not function. For example, if one light bulb goes out, all the other lights will go off because the electricity path in the broken bulb is cut off. This circuit is commonly used in  WHAT IS PARALLEL CIRCUIT? A Parallel circuit is one with several different paths for the electricity to travel. It's like a river that has been divided up into smaller streams, however, all the streams come back to the same point t...
