What is Computer?

DEFINITION - A computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today's computers have both kinds of programming.

Most histories of the modern computer begin with the Analytical Engine envisioned by Charles Babbage following the mathematical ideas of George Boole, the mathematician who first stated the principles of logic inherent in today's digital computer. Babbage's assistant and collaborator, Ada Lovelace, is said to have introduced the ideas of program loops and subroutines and is sometimes considered the first programmer. Apart from mechanical calculators, the first really useable computers began with the vacuum tube, accelerated with the invention of the transistor, which then became embedded in large numbers in integrated circuits, ultimately making possible the relatively low-cost personal computer.

Modern computers inherently follow the ideas of the stored program laid out by John von Neumann in 1945. Essentially, the program is read by the computer one instruction at a time, an operation is performed, and the computer then reads in the next instruction, and so on. Recently, computers and programs have been devised that allow multiple programs (and computers) to work on the same problem at the same time in parallel. With the advent of the Internet and higher bandwidth data transmission, programs and data that are part of the same overall project can be distributed over a network and embody the Sun Microsystems slogan: "The network is the computer."

Tips Perawatan Komputer / Computer Maintenance

Ada beberapa tips yeng perlu diperhatikan sehubungan dengan penggunaan komputer agar lebih aman dan awet diantaranya adalah :

1. Sediakan UPS, Sering kali tegangan listrik turun-naik atau bahkan mati tiba-tiba akan berdampak kurang baik pada PC , terutama PC yang sudah lama, akan mengakibatkan rusaknya Power Supply, rusaknya Hardisk, bahkan Morherboard.Terutama hardisk, hardisk perlu kesetabilan saat bekerja, bila tiba-tiba listrik mati terjadilah kejutan yang bisa menyebabkan tergoresnya track tecordingnya maka timbulah bad sector, bad sector hanya bisa dilihat jika kita check lewat scandisk. bad sector tidak bisa di isi file untuk operasional system maupun menyimpan data, sehingga akan mengurangi kapasitas hardisk itu sendiri. Karena itu di usahakan agar disediakan UPS atau External battery sebagai pengaman bila terjadi mati lampu maka komputer tetap hidup untuk beberapa waktu, sehingga masih ada kesempatan untuk mematikan komputer sesuai prosedur.

2. Stavolt, Untuk UPS yang sudah termasuk stavolt (penstabil naik-turun tegangan) tidak bermasalah, tetapi yang tidak termasuk stavolt di dalamnya maka lebih baik disediakan stavolt tambahan sebagai stabilizer, sehingga walau tegangan listrik naik-turun pun, tidak mengganggu keamanan komputer sendiri.

3. Bersihkan dari debu, biasanya CPU tower di taruh di samping meja user, di letakan dilantai sehingga kemungkinan masuknya debu kedalam CPU besar sekali, Debu sebagai penghantar panas, sehingga apa bila komponen CPU , misalnya Prosesor, walau tersembunyi debu bisa masuk juga, memori/ RAM sering kali kena debu, dan kerja komputer jadi ngadat, hang atau bahkan komputer tidak bisa dinyalakan timbul suara beep…. maka check dan segera bersihkan lah kompenen tersebut , pasang kembali dan nyalakan.

4. Hindari kena Air, tidak menutup kemungkinan keyboard tersiram air minum. Pernah kejadian keyboard saya kena air tanpa sengaja, akhirnya terjadilah konseleting pada lempegan di dalam keyboard , walau sudah dibersihkan dan dijemur sekalipun tidak bisa diperbaiki, sehingga perlu ganti baru.

5. Voltase, Untuk di Indonesia voltase memakai 220 volt, tapi untuk komputer produk Jepang masih 110 volt, sehingga bila menyalakan komputer produk Jepang, jangan lupa sediakan adapter untuk menurunkan voltase dari 220 ke110 volt. kalau tidak wah….kebakar pasti!…

6. Sengatan petir, untuk daerah rawan petir, terutama jaringan komputer yang terhubung menara yang tidak dilengkapi penangkal petir, berbahaya bila terkena petir akan merembet keseluruh jaringan. karena itu sediakan penangkal petir lebih baik.

7. Jauhkan dari medan magnetik, medan magnetik bisa mengganggu performa CPU juga monitor.

8. Demi keamanan data serta system komputer, Pasrikan sudah ada Antivirus dan selalu di update.

9. Pastikan pula ada program utilities tambahan untuk menghapus sisa registry dan sampah dari internet(cokies)
