What is an IP address?


What is  a network or IP address?

  • IP ADDRESS
An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing.

Example of an IP address:


WHAT ARE THE TWO TYPES OF IP ADDRESS

  • IPv4 (Internet Protocol version 4)
  • IPv6 (Internet Protocol version 6)
IPv4
Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number.[2] However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was developed in 1995,[3] and standardized in December 1998.[4] In July 2017, a final definition of the protocol was published.[5] IPv6 deployment has been ongoing since the mid-2000s

IPv6
internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. \

WHAT ARE THE CLASSES OF IP ADDRESS
-CLASS A   1 to 126
-CLASS B   128 to 1
-CLASS C   192 to 233
-CLASS D   224 to 239
-CLASS E   240 to 255


*note 127 is the loop back function of the network*

Class D- Is for multicast
Class E - Renewed for future or experimental purposes


CREATING IP ADDRESS

2.Click Properties 
3.Right click Local Area Connection
4.Click TCP/IP
5.Click Properties

TYPES OF CABLE

What Are The Types Of Cables?


A. Twisted Pair

 
 a cable consisting of two wires twisted around each other, used especially for telephone or computer applications.

 1. STP (Shielded Twisted Pair)
  
 a special kind of copper telephone wiring used in some business installations. An outer covering or shielded is added to the ordinary twisted pair telephone wires; the shield functions as a ground.

 2. UTP (Unshielded Twisted Pair)


 are widely used in the computer and telecommunications industry as Ethernet cables and telephone wires. In an UTP cable, conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference (EMI) from external sources.

B. Coaxial

 
 Coaxial cable, or coax, is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. 

C. Fiber Optic

 Fiber optic cable is a high-speed data transmission medium. It contains tiny glass or plastic filaments that carry light beams. Digital data is transmitted through the cable via rapid pulses of light.

 And now, let's talk about the difference between Straight-Through Cable and Crossover Cable.

A Straight-Through Cable  

  
 Is a type of twisted pair cable that is used in local area networks to connect a computer to a network hub such as a router,

While a Crossover Cable 

 
 Is a type of Ethernet cable used to connect computing devices together directly. Unlike straight through cable, crossover cables use two different wiring standards: one end uses the T568A wiring standard, and the other end uses the T568B wiring standard.
