- 1. 1 Kompetensi dasar > Mengidentifikasi berbagai peralatan teknologi informasi dan komunikasi. 2 Indokator pencapaian hasil belajar . A menyebutkan jenis-jenis peralatan teknologi informasi dan komunikasi. B mengidentifikasi peralatan teknologi informasi dan komunikasi. C menjelaskan berbagai fungsi peralatan teknologi informasi dan komunikasi Materi pembelajaran > Pada dasarnya, peralatan teknologi informasi meliputi tiga perangkat utama. Yaitu system computer, jaringan system komunikasi, net tools. Tugas system computer merupakan perangkan elektronika yang mampu menerima,memperoses, dan menyimpan data. Serta menghasilkan bentuk keluaran berupa teks, gambar, symbol, angka dan suara. Dalam pengoperasian, bentuk, system dan fungsinya, computer terdiri atas dua bagian yaitu hardwear dan softwear. A. Yang pertama hardwear (perangkat keras). Perangkat hardwear computer dapat dikelompokkan menjadi perangkat imput yang diantaranya keyboard dan skanner, Perangkatoutput dan penyimpaann data yang diantaranya monitor dan printer, dan perangkat penyimpana data diantaranya DVdrow, CDrow, floopy disk, compact disk, hard disk, dan flash disk. Tugas Tentang hardwear Jelaskan beberapa pengertian dariitem dibawah ini: A. keyboard B. scanner C. CPU D. monitor E. Printer F. DVD ( CD room) G. Compact disk H. Floopy disk I. Hard disk >
- 2. B. Software Merupakan sebuah program computer yang berisi dari kumpulan instruksi yang dibuat dengan menggunakan. Software terdiri dari Microsoft office. Software terdiri dari 2 yaitu perangkat lunak system seperti windows 7, windows xp. Software aplikasi yaitu Microsoft office word, piwerpoint, Microsoft office exel, dan lain sebagainya. 2. jaringan system komunikasi Jairngan komunikasi merupakan sebuah system yang mampu menghubungkan dan menggabungkan beberapa titik komunikasi menjadi satu kesatuan yang mampu berinteraksi antara satu dengan yang lainnya. 1 telephone 2 ISDN 3 faxsimile 4 viper optic 5 leaset line 6 wireless 7 jaringan komunikasi dengan satelit 8 antena, TV dan radio, seluler 9 komunikasi seluler • telephone: adalah perangkat telekomunikasi dua arah atau lebih untuk bercakap-cakap dengan puas dan mengirim dan menerima suara.
- 3. • ISDN: adalah integrate surface digital network suatu sistem telekomunikasi di mana layanan antara data, suara, video, dan gambar diintegrasikan ke dalam suatu jaringan. • Facsimile: adalah salinan atau reproduksi dari sebuah buku tua, naskah, peta, cetak seni, atau sumber barang lain. • Fiber optic: adalah jaringan komunikasi yang mampu mentransmisikan data yang mampu mentransmisikan data dalam frekuensi tinggi. • Leased line: adalah kontrak pelayanan antara penyedia dan pelanggan. • Wireless: adalah transfer informasi antara dua atau lebih poin yang secara fisik tidak terhubung. Wireless ada dua yaitu yaitu analog dan digital • Jaringan komunikasi dengan satelit: adalah pemancar, penerima, dan penguap gelombang. • Antena, TV dan radio, seluler: Antenna: merupakan arah yang dapat TV atau radio : Seluler: • Komunikasi seluler: adalah salah satu jenis komukasi bergerak, yaitu sebuah komunikasi antara dua terminal dengan salah satu atau dua buah terminal berpindah tempat. C. Net tolls 1. server: adalah sebuah system computer yang menyediakan jenis layanan tertentu dalam sebuah jaringan computer. Recourses: http://id.wikipedia.org/wiki/Server
- 4. 2. client: merupakan sebuah paradigma dalam teknologi informasi yang merujuk kepada cara untuk mendistribusikan aplikasi ke dalam dua pihak: pihak client dan pihak server. http://id.wikipedia.org/wiki/Klien-server 3. Router: adalah sebuh alat yang mengirimkan paket data melalui sebuah jaringan atau internet menuju tujuannya. http://id.wikipedia.org/wiki/Penghala 4. modem: modem berasal dari dua singkatan yaitu modulator dan demodulator. Modulator merupakan bagian yang mengubah sinyal informasi ke dalam sinyal pebawa dan siap untuk dikirimkan. Dan demodulator adalah bahan yang memisahkan sinyal informasi dari sinyal pembawa yang diterima. http://id.wikipedia.org/wiki/Modem D. internet 1 internet user 2. hacker and cracker - hacker is a term of people who provide a useful contribution to the world of networking and operating system, and making programs for network and computer support. - cracker is a term for people who are looking for weaknesses in the system and entered it for personal gain and profit of the systems in the cluster. http://blog.duniascript.com/perbedaan-hacker-dengan-cracker.html 3. organization organization is an organization that play a key role in the evolution of the the internet by developing recommendation, standards, and technology. http://en.wikipedia.org/wiki/Internet_organizations 4. regulation regulation is basically restricting or controlling access to certain aspects or information. http://www.internetsociety.org/regulation 5. carding
- 5. carding is 1. How to share information is with using - via telephone: verify name, job title, department and organization of the person requesting the information and the reason for the request. - Email: include the personal information in a document to be attached to the email, and use encryption or electronic document and send who do you want to send it. - using removable electronic devise - by fax. http://media.education.gov.uk/assets/files/pdf/h/how%20to%20share %20information%20securely.pdf The generation of computer First generation (1940-1956) The first computers used vacuum tubes for circuitry and magnetic drum for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunction. The second generation (1956-1963) The transistor was invented in 1947 but did not see widespread use in computer until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched card for input and printout for output. The third generation (1964-1971)
- 6. The development of the integrate circuit was the hallmark of the third generation of computers. Transistor were miniaturized and placed on silicon chip, called semiconductors. The fourth generation (1971-present) The microprocessor brought fourth generation of computer, as thousands of integrate circuits we built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all components of the computer- from the central processing unit and memory to input/output control-on a single chip. The fifth generation (present and beyond) Fifth generation computing device, based on artificial intelligence, are still in development, thought there are some applications, such as voice recognition, that are being used today. The use of parallel processing a superconductor is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computer in years to come. The goal of fifth- generation computing is to develop that respond to natural language input and are capable of learning and self-organization. http://www.webopedia.com/DidYouKnow/Hardware_Software/2002/FiveGen erations.asp
