Categories network cables
Depending on the quality and type, network cables are classified into categories that help us know the characteristics of them.
The categories of network cables most commonly used are:
- Category 5
- Category 5e
- Category 6
- Category 6
- Category 7
As can be seen, category 5e (enhanced or improved) and category 6A (Augmented), are an improvement of categories 5and 6, respectively, which it has improved the top speed and bandwidth.
The higher the category, the higher the speed of maximum data, the maximum 100 meters distance as its standard.
You can see a table which shows the 5 categories, where V is the maximum velocity, D is the maximum and MHz frequency which can work away.
DHCP
(DHCP stands for Dynamic Host Configuration Protocol, in Spanish "protocol Dynamic Host Configuration") is a network protocol that allows clients to obtain an IP network configuration parameters automatically. It is a protocol for client/server where a server usually has a list of dynamic IP addresses and will allocate these customers as they are left freeKnowing at all times who has been in possession of that IP, how long it has had and who has been assigned later.
Communication Series
RS-232 (Recommended Standard 232, also known as EIA/TIA RS-232C) is an interface that designates a standard for the exchange of a series of binary data between a DTE (Data Terminal Equipment) and DCE (Data Communication Equipment , Data Communication Equipment), although there are others in which the RS-232 interface is also used. An equivalent definition published by the ITU is called V.24. The RS-232 is a connectorDB-25 type (25-pin), although it is normal to find the version of 9-pin (DE-9, or popularly also called DB-9), cheaper and even extended to certain types of peripherals (such as serial mouse PC).
RJ45
When we talk about RJ45 ("Registered Jack" 45) we refer to a telecommunications network interface for wired connection of voice and data equipment.
This connector has 8 pins or connections and may have a specific category depending on the data transfer speed and bandwidth (category 5e, 6, etc.)
The common application is their use in Ethernet network cables under TIA/EIA-568-B standard that defines the arrangement of pins (pinout), but can also be used for other applications.
