Sejarah Perkembangan Mouse
Mouse merupakan salah satu perlengkapan komputer meskipun apabila tidak ada juga komputer masih bisa beroperasi, akan tetapi dengan menggunakan mouse maka kerja kita akan menjadi lebih cepat dan menghemat waktu, lebih cepat dan efisien. Maka tidak ada salahnya jika kita sedikit melihat sejarah perkembangan mouse itu sendiri.
Mouse pertama kali ditemukan oleh Douglas Engelbart dari stanford Research Insitute pada tahun 1963. Mouse adalah suatu alat yang terdiri dari beberapa alat penunjuk ( pointing device ) yang dikembangkan untuk oN Line System (NLS) milik Engelbard. Selain mouse yang awalnyya disebut "bug", juga dikembangkan beberapa alat deteksi gerakan tubuh lainnya yang diletakkan di kepala dan dagu. Karena kenyamanan dsalam penguunaannya, mouse dipilih dan dikembangkan. Mouse pertama yang diciptakan berukuran besar, dan menggunakan dua buah roda yang saling tegak lurus utnuk mendeteksi gerakan ke sumbu Xdan sumbu Y. Engelbart kemudian mematenkan nya pada 17 November 1970, dengan nama penunjuk posisi X-Y untuk sistem tampilan grafis (X-Y position Indicator For A Display System).
Pada waktu itu, sebetulnya Engelbart beraksud pengguna mouse dengan satu tangan secara terus menerus, sementara tangan yang lainnya mengperasikan alat seperti keyboard dengan lima tombol.
Perkembangan selanjutnya dilakukan oleh Bill English di Xerox PARC pada awal tahun 1970, yang menggunakan bola berputar kesegala arah, putaran tersebut dideteksi oleh roda-roda sensor didalam mouse tersebut. Pengembangan inilah yang melahirkan mouse tipe trackball, yaitu mouse terbalik dimana pengguna menggerakkan bola dengan jari.Pada tahun 1980 - 1990 Xerox mempopulerkan penggunaan keyboard QWERTY dengan dua tangan dan menggunakan mouse pada saat dibutukan saja. Mouse sekarang ini mengikuti desain Ecole Polytechnique federale de lausanne (EPFL) yang diinspirasikan oleh profesor Jean-Daniel Nicoud. Jenis yang paling akhir adalah mouse optic dan yang paling mudah dalam perawatannya serta penggunaannya. Mouse jenis ini tidak erlu dibersihkan pada bagian bolanya karena banyak nya debu yang menempel. Mouse optikal pertamakali dibuat oleh Steve Kirsch dari Mouse Systems Corporation. Mouse jenis ini menggunakan LED (Light emitting diode) dan photo dioda untuk mendeteksi gerakan mouse. Mouse optikal petamakali hanya dapat digunakan pada alas (mousepad) khusus yang berwarna metalik bergaris biru - abu-abu. Seiring perkembangan jaman mouse sekarang ini dapat digunakan disemua permukaan yang padat dan rata, kecuali permukaan yang memantulkan cahaya. Mouse saat ini bekerja dengan menggunakan sensor optik yang menggunakan LED sebagai sumber penerangan untuk mengambil beribu-ribu frame gambar selama mouse bergerak. Dan jenis mutakhir dari mouse adalah yang berteknologi laser, pertamakali diperkenalkan oleh logitech, perusahaan mouse terkemuka yang bekerja sama dengan Agilent Technologies pada tahun 2004, dengan nama logitech MX 1000. Logitech mengklaim bahwa mouse laser memiliki tingakt akurasi yang 20 kali lebih besar dari mouse optikal. Meskipun dasar kerja dari mouse optikal dengan mouse laser sama hanya berbeda pada laser pengganti LED. Meskipun begitu jenis mouse ini belum banyak dipergunakan diperkirakan harganya yang masih mahal.
Dari sekian banyaknya perkembangan dari awal sampai yang terakhir yang tidak berubah dari mouse adalah jumlah tombolnya. Semua mouse memiliki tombol satu sampai tiga buah. Mouse pertama memiliki satu tombol. Kebanyakan mouse saat ini, yang didesain oleh microsoft Windows, memiliki dua tombol. Beberapa mouse modernjuga memiliki sebuah wheel untuk memudahkan scrolling. Sementara Ael memperkenalkan mouse satu tombol, yang tidak berubah hingga kini. Mouse modern juga sudah banyak yang tanpa kabel, dengan menggunakan teknologi wireless seperti infra red, gelombang radio ataupun bluetooth. Mouse wireless yang populer saat ini menggunakan gelombang radio dan ataupun bluetooth. Sedangkan mouse yang menggunakan infrared kurang begitu populer karena jarak jangkaunya yang terbatas, selain itu juga kurang begitu praktis karena antara mouse dengan penerimanya tidak boleh ada penghalang.

Tree of life that can also be found on the gunungan used to open the puppet arts. A proof that there is relief that the world has been in Prambanan.
If careful, you can also see various birds relief, this time it is real. Reliefs at Prambanan birds so natural, so the biolog can even identify to the genus level. One relief Jambul Yellow cockatoo (Cacatua sulphurea), which invited questions. The reason, it was only found in the Masakambing Island, an island in the central Java Sea. Then, if the first type are used in Yogyakarta? Please find out the answer himself. For, until now there has not been even one person who can solve the mystery.
