RJ-45 connectors look a lot like standard telephone connectors ... They house eight wires instead of the four wires in a telephone connector.
RJ-45s are not typically found on computers or normal serial equipment, but, because they are so small, they are often used on devices that have a lot of ports very close together.
However, since male connectors are more susceptible to injury than female, most expensive computing hardware these days has female connectors, while cables are male on both ends.
Since RS-232 defines signals that are not used for most standard communication, sometimes DB-25 connectors are missing unneeded pins.
Originally, there was no standardization of the gender of connectors and serial devices.
Both connectors and serial devices could be either gender.
Most serial ports follow a standard called the RS-232 specification.
RS-232 is a sort of "do all" specification, and as such is not perfect in every situation.
This is something to keep in mind when connecting terminals to computers in other rooms.
Because of the fact that RS-232 defines signals that go unused in standard types of communication, and because the traditional DB-25 connector is large an unwieldy (especially for small equipment, like laptops), many alternate serial connectors have come into widespread use.
