Preface to the Student & Pengaturan

Getting the Most from This Text

A good way to approach each chapter is to: 1) Look over the Student Learning Objectives on the chapter opener; 2) Turn to the end of the chapter and read the Summary Outline and Important Terms; 3) Read over the major headings and subheadings and think of how they are related.

Lanjut: 4) Read the chapter and note the important terms in boldface type and in italic type; 5) Relate photos and photo captions to the text (One picture is worth a thousand words); 6) Go over the Summary Outline and Important Terms again, paying particular attention to the boldface terms.

Lanjut: 7) Take the Self Test. Reread those section you do not fully understand; 8) Answer the questions in the Review Exercises.

Jika dosen hadir kurang dari 50% jumlah hari kuliah standar, maka pelajaran via e-learning dan tidak ada nilai D dan E kecuali untuk para mahasiswa yang jumlah kehadirannya kurang dari 50% tetap akan langsung diberi nilai E.

Antar-muka dan Periferal 3

Materi perkuliahan akan dibagi menjadi tiga bagian. Bagian pertama fokus pada variasi terminal yang tersedia, kebanyakan digunakan untuk masukan dan keluaran. Bagian kedua menyajikan perangkat untuk memasukkan data menggunakan source-data automation – dalam kata lain, data dimasukkan menuju komputer secara langsung dari sumber, tanpa perlu manual data entry. Bagian ketiga mendeskripsikan perangkat yang digunakan untuk keluaran semata.

We are in transition from an industrial society to an information society. The force driving this transition are the computer and the people who strive to exploit its seemingly endless capabilities in their work and in their leisure. The chapters offer an overview of information technology and applications (special: interfacing and peripheral). Once you have read and understood the material in this text and have had hands-on experience with computers, you will be poised to play an active role in the “computer revolution”.

The layout and organization of the text and its content are designed to present concepts in an interesting, logical, and informative manner, and to be used as a reference for the reinforcement of classroom lectures.

I/O DEVICES: OUR INTERFACE WITH THE COMPUTER

Data are created in many places and in many ways. Before data can be processed and stored, they must be translated into a form the computer can interpret. For this, we need input devices. Once the data have been processed, they must be translated back into a form that we can understand. For this, we need output devices. These input /output devices, also referred to as peripheral devices, enable communication between us and the computer.

The diversity of computer applications has encouraged manufacturers to develop and market a variety of I/O methods and hardware. Innovative I/O devices are being introduced continuously into the marketplace. For example, voice recognition devices accept data (input) from human speech. Speech synthesizers produce simulated human speech as output.

TEKNIK ANTARMUKA KOMPUTER MIKRO

Tujuan utama dalam perancangan sistem berbasis komputer mikro adalah untuk menghasilkan produk: 1) Terpercaya, 2) Unjuk kerja tinggi, 3) Mudah digunakan –> pada biaya terendah. Bagian penting dari perancangan adalah antarmuka di antara komputer mikro dan peralatan yang dipantau.

Apa yang anda ketahui tentang Interface? Sebutkan peripheral yang biasa anda temukan pada komputer? Berikut ini termasuk material antar-muka dan periferal: 1) bus, storage devices dan device I /O; 2) interkoneksi, sinyal elektrik dan logika, dan protokol /signalling.

Termasuk material antar-muka dan periferal adalah input /output devices. Student learning objectives: 1) To describe the use and characteristics of the different types of terminals; 2) To explain alternative approaches to and devices for data entry; 3) To describe the operation and application of common output devices.

The people in administrative department with each of knowledge workers routinely deals with computer-generated information, each person needs a terminal to interact with the computer. Hal itu tergantung jalur masukan /keluaran digital atau analog untuk implementasi antarmuka. Keputusan diperlukan pada bagai mana cara memanfaatkan jalur ini guna memenuhi persyaratan antarmuka secara efisien. Dalam banyak situasi jalur masukan dan keluaran yang ada perlu dicadangkan untuk penggunaan lain. Kebutuhan untuk mengenalkan H /W tambahan untuk implementasi antarmuka, tipe dan kompleksitas tergantung pada: 1) komputer mikro, 2) perangkat tambahan, 3) ???
