Tugas Jaringan Komputer - VClass, LAN Design (B)

Lab 5.1.13b Building a Hub-based Network



Objective
• Create a simple network with two PCs using a switch
• Identify the proper cable to connect the PCs to the switch
• Configure workstation IP address information
• Test connectivity using the ping command

Background / Preparation
This lab focuses on the ability to connect two PCs to create a simple switch-based Ethernet LAN using two workstations. A switch is a networking concentration device sometimes referred to as a multiport bridge. Switches are relatively inexpensive and easy to install. When operating in full- duplex mode, they provide dedicated bandwidth to workstations. Switches eliminate collisions by creating microsegments between ports to which the two workstations are attached. They are appropriate for small to large LANs with moderate to heavy traffic.
In addition to the physical and data link connections, which are Layers 1 and 2, the computers must also be configured with the correct IP network settings, which is Layer 3, so that they can communicate. Since this lab uses a switch, a basic Category 5/5e UTP straight-through cable is needed to connect each PC to the switch. This is referred to as a patch cable or horizontal cabling, which is used to connect workstations and a typical LAN. Start this lab with the equipment turned off and with cabling disconnected. Work in teams of two with one person per PC. The following resources will be required:
• Two workstations with an Ethernet 10/100 NIC installed
• Ethernet 10BaseT or Fast Ethernet switch
• Several Ethernet cables, which are straight-through and crossover, to choose from for connecting the two workstations


Step 1 Identify the proper Ethernet cable and connect the two PCs to the switch
a. The connection between the two PCs and the switch will be accomplished using a Category 5 or 5e straight-through patch cable. Locate two cables that are long enough to reach from each PC to the hub. Attach one end to the NIC and the other end to a port on the hub. Be sure to examine the cable ends carefully and select only a straight-through cable.
b. What kind of cable is required to connect from NIC to switch? Straight-through cable
c. What is the category rating of the cable? Category 5 or 5e
d. What is the AWG wire size designation of the cable? 24 AWG

Step 2 Verify the physical connection
a. Plug in and turn on the computers. To verify the computer connections, insure that the link lights on the both PC NICs and the hub interfaces are lit. Are all link lights lit? They should be otherwise troubleshoot

Step 3 Access the IP settings window
Note: Be sure to write down the existing IP settings, so that they can be restored at the end of the lab. These include IP address, subnet mask, default gateway, and DNS servers. If the workstation is a DHCP client, it is not necessary to record this information.

Windows 95/98/Me users should do the following:
• Click on Start > Settings > Control Panel and then click the Network icon.
• Select the TCP/IP protocol icon that is associated with the NIC in this PC and click on Properties.
• Click on the IP Address tab and the Gateway tab.

Windows NT/2000 users should do the following:
• Click on Start > Settings > Control Panel and then open the Network and Dial-up
Connections folder.
• Click and open the Local Area Connection icon.
• Select the TCP/IP protocol icon that is associated with the NIC in this PC.
• Click on Properties and click on Use the following IP address.

Windows XP users should do the following:
• Click on Start > Settings > Control Panel and then click the Network Connection icon.
• Select the Local Area Network Connection and click on Change settings of this connection.
• Select the TCP/IP protocol icon that is associated with the NIC in this PC.
• Click on Properties and click on Use the following IP address.

See the example below:




Step 4 Configure TCP/IP settings for the two PCs
a. Set the IP address information for each PC according to the information in the table.
b. Note that the default gateway IP address is not required, since these computers are directly connected. The default gateway is only required on local area networks that are connected to a router.

Computer	IP Address	Subnet mask	Default Gateway
PC – A	192.168.1.1	255.255.255.0	Not Required
PC – B	192.168.1.2	255.255.255.0	Not Required

Step 5 Access the Command or MS-DOS prompt
a. Use the Start menu to open the Command Prompt (MS-DOS-like) window: Windows 95/98/Me users should do the following:
Start > Programs > MS-DOS Prompt
Windows NT/2000 users should do the following:
Start > Programs > Accessories > Command Prompt
Windows XP users should do the following:
Start > Programs > Accessories > Command Prompt

Step 6 Verify that the PCs can communicate
a. Test connectivity from one PC to the other through the hub by pinging the IP address of the opposite computer. Use the following command at the command prompt.
C:>ping 192.168.1.1 (or 192.168.1.2)
b. Look for results similar to those shown below. If not, check the PC connections and TCP/IP
settings for both PCs. What was the ping result?
Results could possibly be: Sent=4 Received=3 Lost=1 (this is due to ARP) Any other results probably indicate an error



Step 7 Confirm the TCP/IP network settings
Windows 95 / 98 / Me users should do the following:
a. Type the winipcfg command from the MS-DOS Prompt. Record the results.
Answers will vary depending on if Computer A or B is used.
Examples for Computer A IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
Default Gateway:

Windows NT / 2000 / XP users should do the following:
b. Type the ipconfig command from the Command Prompt. Record the results.
Answers will vary depending on if Computer A or B is used.
Examples for Computer B IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
Default Gateway:


Step 8 Restore the PCs to their original IP settings, disconnect the equipment, and store the cables

Tugas Bahasa Indonesia 2 - Naskah Pidato

PENGARUH INTERNET TERHADAP REMAJA

Assalamualaikum wr wb, Bapak/ ibu guru beserta rekan-rekan yang saya hormati, pertama-tama marilah kita panjatkan puji dan syukur kepada tuhan yang maha esa yang telah memberikan rahmat dan hidayahnya kepada kita semua sehingga kita dapat berkumpul ditempat ini, saya ucapkan banyak terimakasih atas kesempatan yang telah diberikan kepada saya untuk menyampaikan sebuah pidato yang berjudul “Pengaruh Internet Terhadap Remaja”.

Sebelum saya memulai berpidato saya ingin menyampaikan batasan masalah yang akan saya sampaikan didalam pidato hari ini, yakni diantaranya ; pengaruh internet terhadap remaja dilihat dari segi positif dan dari segi negative.

Internet, kata yang tidak asing di telinga setiap orang, terutama para remaja yang senantiasa bergaul dengan mewahnya dunia yang bertekhnologi, mewah, dan praktis, Internet bisa didapatkan dimanapun kita berada, dengan bermodalkan telepon selular yang memiliki koneksi internet, internet dapat diakses dengan mudahnya melalui HP dimanapun kita berada, atau jika tidak, disetiap sudut kota pasti terdapat sebuah Warung yang menjual jasa internet atau yang biasa disebut dengan “Warnet”, Dunia Informasi Tanpa Batas, begitulah orang-orang menyebutnya, saya sendiri tidak begitu yakin tapi apa boleh dikata memang begitu keadaannya, dengan adanya Internet, Akses atau jalan terhadap penyampaian Informasi-informasi yang ada didunia ini dapat diambil dengan mudahnya seraya membalikkan tangan atau mengejapkan mata.

Banyak Ilmu pengetahuan yang begitu melimpah disana, informasi mengenai apapun dapat kita temukan di jagat internet ini, lalu apa hubungannya dengan Siswa? Tentu saja sangat erat hubungannya dengan siswa karena siswa tidak luput dengan yang namanya informasi dan ilmu pengetahuan, internet ini adalah media yang paling efektif dan mudah untuk didapatkan dan diakses oleh siapa saja dimanapun, walaupun tak dapat dipungkiri bahwa karena adanya kebebasan ini dapat terjadi pula penyalah gunaan fasilitas internet sebagai sarana untuk Kriminalitas atau Asusila, siswa yang baru mengenal internet biasanya menggunakan fasilitas ini untuk mencari hal yang aneh-aneh? Seperti gambar-gambar yang tidak senonoh, atau video-video aneh yang bersifat “asusila” lainnya yang dapat mempengaruhi jiwa dan kepribadian dari siswa itu sendiri, sehingga siswa terpengaruh dan mengganggu konsentrasinya terhadap proses pembelajaran disekolah.

Namun demikian tidak semua siswa melakukan hal yang demikian, hanya segelintir siswa-siswa yang usil saja yang dapat melakukannya karena kurang memiliki rasa tanggungjawab terhadap diri pribadi dan sekitarnya, namun pada umumnya internet digunakan oleh setiap siswa untuk mencari atau mendapatkan informasi yang berhubungan dengan materi pelajaran yang ia terima disekolah, hal tersebut memungkinkan siswa menjadi lebih kreatif dan lebih aktif dalam mencari sumber informasi dan ilmu pengetahuan dibandingkan dengan siswa-siswa yang hanya duduk diam didepan meja dan mendengarkan gurunya berbicara.

Hal ini dapat menjadi sebuah motivator terhadap siswa untuk terus berkembang dan juga dapat berfungsi sebagai penghancur (generasi muda), remaja adalah makhluk yang rentan terhadap perubahan disekitarnya, dia akan mengikuti hal yang paling dominant yang berada didekatnya jadi kemungkinan terjadinya perubahan yang drastis dalam masa-masa remaja akan mendorong kearah mana remaja itu akan berjalan, kearah positif atau negative tergantung dari mana di memulai.

Remaja yang kesehariannya bergaul dengan internet akan lebih tanggap terhadap perubahan informasi disekitarnya karena ia terbiasa dan lebih mengetahui tentang informasi-informasi tersebut sehingga dia lebih daripada yang lainnya. Tetapi selain itu, remaja yang memiliki kecenderungan pada hal yang negative justru sebaliknya, dia akan nampak pasif karena hanya diperbudak oleh kemudahan dan kayaan informasi dari internet tersebut.

Maka dari itu alangkah baiknya jika kita bisa dengan bijak menggunakan fasilitas ini dengan sebaik-baiknya dalam hal yang positif demi kemajuan diri dan pribadi kita, dan selaku remaja kita semua harus dapat menguasai teknologi yang sedang berlari kencang pada era ini, karena dengan demikian kita pun akan ikut berlari menyongsong masa depan.

Atas perhatiannya saya ucapkan terimakasih, akhirul kata, wassalamualaikum wr wb.
