Introduction to Cabling

RELAX CORNER
* Joke *

A wife was making a breakfast of fried eggs for her husband. Suddenly, her husband burst into the kitchen. 'Careful,' he said, 'CAREFUL! Put in some more butter! Oh my gosh! You're cooking too many at once. TOO MANY! Turn them! TURN THEM NOW! We need more butter. Oh my gosh! WHERE are we going to get MORE BUTTER? They're going to STICK! Careful. CAREFUL! I said be CAREFUL! You NEVER listen to me when you're cooking! Never! Turn them! Hurry up! Are you CRAZY? Have you LOST your mind? Don't forget to salt them. You know you always forget to salt them. Use the! Salt. USE THE SALT! THE SALT!' The wife stared at him. 'What in the world is wrong with you?You think I don't know how to fry a couple of eggs?' The husband calmly replied, 'I just wanted to show you what it feels like when I'm driving.'

Wakakaka.......

How Do I Feel....

Today I felt quite good because lecturer taught us more information about cabling... actually this type of question was come out in our test... now, we more understand about it...

My friends also presented their slides... Thanks for them because we gained benefit from the presentation...especially the...DOGPILE...and the introduction to blog setting...

The lesson I attended today....

1. LAN Techonology Cabling :

    a) Cable is the medium through which information usually moves from one network device to another.

    b) Several types of cable are commonly used with LANs.

    c) In some cases,a network will utilize only one type of cable, other networks will use a variety of cable    types.

2. Types of Cables :

   

    Unshielded Twiested Pair (UTP) cable 

    Shielded Twisted Pair (STP) cable

    Coaxial Cable

    Fiber Optic Cable

    Wireless LANs

3. Unshielded Twisted Pair (UTP) cable

- Four pairs of wires inside the jacket

- each pair is twisted

- help tp eliminate interfereance from adjacent pairs and other electrical devices

4. Category 1 : Voice 9wayar Telefon)

    Category 2 : Data to 4 Mbps (Local Talk)

    Category 3 : Data to 10 Mbps (Ethernet)

    Category 4 : Data to 20 Mbps (16 Mbps Token Ring)

    Catogory 5 : Data to 100 mbps (Fast Ethernet)

5. The standard connector for unshielded twisted pair cabling is an RJ-45 connector

6. Shielded Twisted Pair (STP) cable

- is a type of cable wrapped in a foil shielding

- to help provide a more reliable data communication

- using TOKEN RING topology

7. Coaxial cable

- a single copper conductor at its center

- a plastic layer provides insulation

- the metal shield helps to block interference

- Bayone-Neill-Concelman (BNC) connector

- T-connector, barrer connector, terminator

8. Fibre Optics

- consists of a center glass core surrounded by several layers

- transmit light rather than electronic signals

- eliminate the problem of electrical interference

- transmit signals over much longer distances than coaxial and twisted pair

9. 10BaseT : Unshielded Twisted Pair : 100 meters

    10Base2 : Thin Coaxial : 185 meters

    10Base5 : Thick Coaxial : 500 meters

    10BaseF : Fiber Optic : 2000 meters

10. Linear Bus : Coax, twisted pair, Fiber : Ethernet, Local talk

      Star : Twisted pair, fiber : Ethernet, Local talk

      Star-wired Ring : Twisted pair : Token ring

      Tree : Coax, twisted pair, fiber ; ethernet

 Introduction to Computer Network

*New Relax Corner*

~JOKE~

A doctor and a lawyer were talking at a party.

Their conversation was constantly interrupted by people describing their ailments and asking the doctor for free medical advice.

After an hour of this, the exasperated doctor asked the lawyer, "What do you do to stop people from asking you for legal advice when you're out of the office?"

"I give it to them," replied the lawyer, "and then I send them a bill."

The doctor was shocked, but agreed to give it a try.

The next day, still feeling slightly guilty, the doctor prepared the bills.

When he went to place them in his mailbox, he found a bill from the lawyer.

…HAhahaha….

~LAUGH~

~ENJOY~

 

Beautiful Firework

*My Word*

It was the last lesson before mid-sem break.  

~Time flies over us, but leaves its shadow behind.~.

~There is never enough time, unless you're serving it.~

No doubt, I learnt new knowledge about network. I believe that it will help us in our future as it broadens our mind about network. It benefits us. Hopefully, I can absorb as much knowledge as possible.

~Time is the coin of your life.

   It is the only coin you have,

and only you can determine how it will be spent.~

Now, I would like to share the lesson I had learnt in my class:

  1.     Topology species the geometric arrangement of the network.

  2.     A protocol is a set of rules that governs the communications between computers on a network. 

  3.     Architecture refers to one of the two major types of network architecture: Peer-to-peer or client/server. 

  4.     Topology: Bus network, star network, ring network and hybrid network.

  5.     Protocol: 

-The Ethernet protocol is a common logical bus topology protocol  

-LocalTalk is a common logical bus or star topology protocol

-Token ring is a common logical ring topology protocol

The Ethernet protocol allows for linear bus, star, or tree topologies. Data can betransmitted over wireless access points, twisted pair, coaxial, or fiber optic cable.

  6.     Architecture
