HOW TO SHARE FILE AND PRINTER ON A NETWORK?

PRELIMINARY STEPS:

1.  Create an IP address

2. Configure the IP address

3. Set Windows Firewall settings

 •Turn off firewall

  - Firewall – is a network security system that can monitor and control incoming and outgoing network traffic based on predetermined security rules.

4. Set up a home or small office network

 - Network Setup Wizard – is a built-in feature of windows that let you setup a network for computer running Microsoft Windows operating systems.

WHAT IS A NETWORK ADDRESS?

NETWORK ADDRESS

Is more commonly known as IP ADDRESS. It is the numeric address of a computer connected to the network. It is a set of numbers, called as "octets" or "dotted decimal" notation that identifies any network device.       

It can be compared to the physical address that we use for our homes which uniquely identifies it from the rest of the homes in our neighborhood, town, city, province, country and the whole wide world.

EXAMPLES:
                
                        -172.16.254.1
                  -192.168.1.1              

WHAT ARE THE VERSIONS OF IP ADDRESS? 

There are two versions of IP that currently coexist in the global Internet: IP version 4 (IPv4) and IP version 6 (IPv6). IP addresses are made up of binary values and drive the routing of all data over the Internet. IPv4 addresses are 32 bits long, and IPv6 addresses 128 bits long.

                    1. IPv4- IP version 4

                           - It is the standard version

                    2. IPv6 - IP version 6
                           - It is the advanced version

IPv4 addresses are canonically represented in dotted-decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16.254.1. Each part represents a group of 8 bits (octet) of the address.

BINARY DIGITS OF 172

WHAT ARE THE CLASSES OF IP ADDRESS?

With an IPv4 IP address, there are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B, and C are commonly used. Each class allows for a range of valid IP addresses, shown in the table below.

Note:

127 - is the loop back function of a network

CLASS D - is for multicast

CLASS E - is reserved for future or experimental purpose

WHAT ARE THE TYPES OF CABLE?

CABLE

 ~ Alternatively referred to as a cord, connector or plug, a cable is one or more wires covered in a plastic covering that allows for the transmission of power or data between devices. The picture is an example of what the power cord may look like for your computer or monitor. The power cord is just one example of thousands of other cables found in and around computers.

TYPES OF CABLE

A.           TWISTED PAIR

~ Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other.

There are 2 types of twisted pair cable, they are:

a.)           STP (Shielded Twister Pair)

~ is a special kind of copper telephone wiring used in some business installations. An outer covering or shield is added to the ordinary twisted pair telephone wires; the shield functions as a ground.

b.)           UTP (Unshielded-Twisted Pair)

~is most certainly by far the most popular cable around the world. UTP cable is used not only for networking but also for the traditional telephone(UTP-Cat 1).

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. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis.

C.    FIBER OPTIC

~An optical fiber cable, also known as a fiber optic cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. 

WHAT IS THE DIFFERENCE BETWEEN STRAIGHT-THROUGH CABLE AND CROSS-OVER CABLE?

        STRAIGHT-THROUGH         CROSS OVER

Straight-through- it is used to connect DIFFERENT DEVICES.

Crossover- it is used to connect SAME TYPE OF DEVICES.
