Answer:
The technician has made a cross-over cable.
Explanation:
The network is a platform that provides two or more computers to communicate. There different types of networks, namely, local-area network (LAN), wide-area network (WAN), MAN or metropolitan-area network etc.
Devices in a network can be connected with cables (ethernet IEEE 802.3) or wirelessly (wifi IEEE 802.11a/n/g). Wiring standards are strictly followed in ethernet configuration.
Two ethernet wiring standards are T568A and T568B. The difference in both standards are the pin configuration and their position in a wire defines a cable system.
When a T568A or T568B are used on both ends of a twisted pair cable, it is called a straight-through cable. When T568A is used on one end and T568B on the other, it is called a cross-over cable.
These cable systems are used for different applications. the straight-through cable is used for connecting devices that are not the same like router to switch, switch to computer etc. The cross-over cable connects similar network devices like router to router, switch to switch etc.
