IP Address

That is the addressing system on the network which is represented by a series of numbers in the form of a combination of 4 series of numbers between 0 to 255, each separated by a dot (.) starting from 0.0.0.1 to 255.255.255.255 and is unique.

IP / TCP

TCP (Transmission Control Protocol): the protocol in charge of sending data.

IP (Internet Protocol): the protocol in charge of collecting data.

TCP / IP is a protocol that serves to unite computers with different machines and OS (Operating System) to be able to communicate with each other.

IP class

Class A (/8)

Hosts : 16,777,216

IP Range : 0 – 126

Layout: Network.Host.Host.Host

Subnet : 255.0.0.0

Class B (/16)

Hosts : 65,535

IP Range : 128 – 191

Layout: Network.Network.Host.Host

Subnet : 255.255.0.0

Class C (/24)

Hosts : 254

IP Range : 192 – 223

Arrangement : Network.Network.Netwok.Host

Subnet : 255.255.255.0

Notes :

The IP IP range of 127.x.x.x is not used because it functions as a loopback on the computer’s own localhost.

Work With IP Address

The IP address is 32 bits long and is divided into two parts: the Network part and the Host part. This boundary between Network (N) and Host (H) depends on the first few bits. The final limit for the network is 254.

Class A

Subnet : 255.0.0.0

Arrangement : (N).(H).(H).(H)

The first octate must be the same as the computer on the network.

Example IP: 120.0.1.92, 120.1.1.92, etc

Class B

Subnet : 255.255.0.0

Arrangement : (N).(N).(H).(H)

The first two octates must be the same as the computer on the network.

Example IP : 140.100.1.92, 140.100.2.1

Class C

Subnet : 255.255.255.0

Arrangement : (N).(N).(N).(H)

The first three octets must match the computers on the network.

Example IP : 193.10.10.1 (Host IP/IP of the 1st computer)

193.10.10.2 (2nd computer host IP/IP)

Transmission Media and Supporting Techniques

Transmission Media is a physical path between transmitter and receiver to transmit data. Transmission media can be classified as guided or unguided. Both can occur in the form of electromagnetic waves.

Guided media (guided):

STP (Shield Twisted Pair)

UTP (Unshield Twisted Pair)

· Coaxial Cable

· Fiber Optic

Unguided Media (Wireless Transmission)

· Air

· Atmosphere

Supporting Technical:

Modular

A device used to connect a computer network that is blocked by a wall with an additional face plate.

Modular staining for type TIA 568A :

Striped orange, orange, brown striped, brown, blue striped, blue, striped green and green.

Modular staining for the TIA 568B type:

Striped green, green, striped brown, brown, striped blue, blue, striped orange and orange.

NIC (Network Interface Card)

Is a peripheral or a card that serves as a bridge from a computer to a computer network.

Speed ​​of NIC

· 10 base T

· 100 base T

1000 base T (Gigabyte)

· 10/100 base T

10/100/1000 base T

NICs can communicate with each other, if one model or type is the same as another.

The example is :

10 base T —> 10 base T

100 base T —> 100 base T

1000 base T —> 1000 base T

10/100 base T —> 10 base T or 100 base T

10/100/1000 base T —> 10 base T or 100 base T or 1000 base T.

Notes :

A NIC with 10/100 base T will get a maximum speed of 100 Mbps when using standard T568A or T568B cabling and using a NIC with 100 base T. If using a NIC with 10 base T, a NIC with 10/100 base T will get a speed of about 10 Mbps . Likewise with 10/100/1000 base T NICs.

Patch Panel

It has 4 blocks and each block has 6 ports. This type of block must be a straight model, if one block is of type T568A then the other block must be T568A and vice versa.

Cable coloring on the patch panel for the TIA 568A type:

Blue, striped blue, green, striped green, orange, orange striped, brown and striped brown.

Cable coloring on the patch panel for the TIA 568B type:

Blue, striped blue, people, orange stripes, green, striped green, brown and brown stripes.

Wiring Standard

· Type T568A

Striped green, green, striped orange, blue, striped blue, orange, striped brown, brown.

· Type T568B

Striped orange, orange, striped green, blue, striped blue, green, striped brown, brown.

From these standards, the result is a wiring model:

· Cross over/Cross Link Cable

The type of cabling that is used only for 2 computers (Peer to Peer) is done, if the device standards are the same (has RAM, OS and storage media). This type uses T568A and T568B or T568B and T568A at the base of the cable.

Test results:

The order of the green numbers that appear on the indicator is 3 6 1 4 5 2 7 8.

· Straight Cable

This type of cabling is done, if the device standards are different and use a switch as a connector between computers. This type uses T568A and T568A or T568B and T568B at the base of the cable.

Test results:

The order of the green numbers that appear on the indicator is 1 2 3 4 5 6 7 8.

· Roll Over / Console

Connecting a computer with a Cisco device (Router Console) with the same installation technique, namely flip swap.

Test results:

The color arrangement that appears on the indicator is 8 7 6 5 4 3 2 1.

Switch

Is a network device that works in the Data-link layer similar to a bridge, serves to connect many LAN segments into one larger network.

Category Switch

· Manageable: can be arranged

Unmanageable: cannot be set/dsetting

Uplink

Is the relationship between one switch to another switch

maybe that’s all I can share. hopefully useful and used as well as possible.
