NIC:
Network Interface Controller is a computer hardware component that connects a computer to a computer network.
TCP/IP:
The Transmission Control Protocol (TCP), sometimes called the Transfer Control Protocol, is one of the core protocols of the Internet Protocol Suite. TCP is one of the two original components of the suite, complementing the Internet Protocol (IP), and therefore the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered delivery of a stream of bytes from a program on one computer to another program on another computer. TCP is the protocol that major Internet applications such as the World Wide Web, email, remote administration and file transfer rely on. Other applications, which do not require reliable data stream service, may use the User Datagram Protocol (UDP), which provides a datagram service that emphasizes reduced latency over reliability.
SWITCH:
A network switch or switching hub is a computer networking device that connects network segments.
The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (Layer 3) and above are often referred to as Layer 3 switches or multi layer switches.

CABLE:
1. Fiber Optical – Transfers the date in light speed.
2. Twisted Pair Cable / Unshielded Twisted Pair Cable
a. Cat 1
b. Cat 2
c. Cat 3
d. Cat 4
e. Cat 5
f. Cat 6
3. Coaxial CableRJ45 PIN:
RJ45 is a type of registered jack. As a registered jack, telephone RJ45 specifies the physical male and female connectors as well as the pin assignments of the wires in a telephone cable. The original RJ45 uses a special keyed 8P2C modular connector, with pins 5 and 4 wired for tip and ring of a single telephone line and pins 7 and 8 connected to a programming resistor. It is used with a high speed modem.
