Acer: Masa Kejayaan Komputer Sudah Usai 
Jakarta - Acer nampaknya yakin masa kejayaan komputer dalam bentuk yang konvensional sudah usai. Rencana agresif di arena tablet pun dimulai perusahaan asal Taiwan itu.

Keyakinan itu disampaikan JT Wang, Chairman Acer yang menggantikan sementara Gianfranco Lanci sebagai CEO Acer. Seperti dikutip detikINET dari Bloomberg, Selasa (12/4/2011), Acer akan fokus di tablet.

Wang berencana melakukan restrukturisasi agar Acer mengembangkan produk lebih dari sekadar laptop. Salah satunya adalah tablet Iconia Tab A500 yang akan hadir pada 24 April 2011.

"Kita mungkin tak akan bisa kembali ke masa-masa kejayaan, jika mengandalkan penjualan notebook dan netbook kita hanya bisa mendapatkan pertumbuhan satu digit dibandingkan 20 - 30 persen di masa lalu," ujar Wang.

Wang mengaku Acer memiliki rencana agresif untuk masuk ke pasar tablet dalam dua tahun ke depan.

Iconia Tab A500 menggunakan sistem operasi Android 3.0 alias Honeycomb. Perangkat dengan layar 10.1 inchi itu memiliki koneksi WiFi, dua kamera dan penyimpanan 16GB. Iconia Tab A500 menggunakan prosesor Nvidia Tegra 2.

Tips Memakai Komputer Agar Tak Merusak Mata

Jakarta - Tidak hanya menyebabkan kondisi mata menjadi lelah, menatap layar komputer terlalu lama juga bisa merusak mata. Agar hal tersebut tidak terjadi, berikut beberapa cara menggunakan komputer yang tepat.

Menurut sebuah penelitian, layar komputer tidak memancarkan radiasi berbahaya seperti sinar X atau cahaya ultraviolet. Jadi, kelelahan yang biasa terjadi saat menatap layar komputer terlalu lama bukan dikarenakan oleh paparan sinar monitor, melainkan oleh faktor lain, seperti yang dikutip dari lifemojo.

Faktor lain tersebut adalah pencahayaan yang buruk, posisi komputer atau barang lain yang tidak benar. Ketegangan yang berlebihan pada mata atau yang biasa disebut Computer Vision Syndrome dapat mengakibatkan mata gatal atau terasa terbakar, penglihatan ganda atau kabur serta sakit kepala.

Untungnya ada beberapa langkah yang dapat Anda lakukan untuk melindungi mata dari kelelahan dan ketegangan. Hal yang paling utama dan harus dilakukan adalah pengaturan posisi komputer dan pencahayaan.

1. Jauhkan komputer kurang lebih 20-30 inci atau sekitar panjang lengan dari mata Anda. Usahakan agar monitor sejajar dengan arah pandang mata Anda.

2. Miringkan layar monitor ke arah belakang sebanyak 19 hingga 20 derajat. Hal ini berguna untuk mendapatkan jarak pandang yang optimal.

3. Atur cahaya monitor agar tidak terlalu silau atau terlalu redup. Jika cahaya terlalu terang, gunakan filter atau pelindung anti-silau. Jangan lupa untuk mengatur brightness untuk mendapatkan kontras yang tepat antara huruf dan latar belakang. Jika melihat adanya flicker pada layar komputer, sebaiknya segera ganti monitor Anda.

4. Jika diharuskan membaca dokumen yang panjang atau menggunakan komputer dalam waktu yang lama, cobalah untuk menggunakan layar komputer serta ukuran huruf yang lebih besar. Ada baiknya menggunakan layar komputer LCD karena lebih bisa diterima dengan baik oleh mata.

5.  Gunakan kursi yang dapat diatur tinggi-rendah dan senderan punggungnya. Selain itu, gunakan juga alas kerja atau meja yang stabil dan tidak mudah goyah.

Computer security

Computer security is a branch of computer technology known as information security as applied to computers and networks. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users. The term computer system security means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively. The strategies and methodologies of computer security often differ from most other computer technologies because of its somewhat elusive objective of preventing unwanted computer behavior instead of enabling wanted computer behavior.

Laptop

A laptop (notebook)^[1][2] is a personal computer for mobile use.^[3][4][5] A laptop integrates most of the typical componentsof a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or apointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. A laptop battery in new condition typically stores enough energy to run the laptop for three to five hours, depending on the computer usage, configuration and power management settings. When the laptop is plugged into the mains, the battery charges, whether or not the computer is running.

Portable computers, originally monochrome CRT-based and developing into the modern laptop, were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives. As portable computers became smaller, lighter, and cheaper and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes.

Institutes of the Christian Religion

Institutes of the Christian Religion (Institutio Christianae religionis) is John Calvin's seminal work on Protestant systematic theology. Highly influential in the Western world^[1] and still widely read by theological students today, it was published in Latin in 1536 and in his native French in 1541, with the definitive editions appearing in 1559 (Latin) and in 1560 (French).

The book was written as an introductory textbook on the Protestant faith for those with some previous knowledge of theology and covered a broad range of theological topics from the doctrines of church and sacraments to justification by faith alone andChristian liberty. It vigorously attacked the teachings of those Calvin considered unorthodox, particularly Roman Catholicism to which Calvin says he had been "strongly devoted" before his conversion to Protestantism. The over-arching theme of the book – and Calvin's greatest theological legacy – is the idea of God's total sovereignty, particularly in salvation and election.^[1]

The Institutes is a highly-regarded secondary reference for the system of doctrine adopted by the Reformed churches, usually called Calvinism.

Catholic

The word catholic (derived via Late Latin catholicus, from the Greek adjective καθολικός (katholikos), meaning "universal"^[1][2]) comes from the Greek phrase καθόλου (kath'holou), meaning "on the whole," "according to the whole" or "in general", and is a combination of the Greek words κατά meaning "about" and όλος meaning "whole".^[3][4] The word in English can mean either "including a wide variety of things; all-embracing" or "of the Roman Catholic faith." as "relating to the historic doctrine and practice of the Western Church."^[5]

It was first used to describe the Christian Church in the early 2nd century to emphasize its universal scope. In the context of Christianecclesiology, it has a rich history and several usages. In non-ecclesiastical use, it derives its English meaning directly from its root, and is currently used to mean

• universal or of general interest; or
• liberal, having broad interests, or wide sympathies.^[6]
• inclusive, inviting and containing strong evangelism.

The term has been incorporated into the name of the largest Christian communion, the Catholic Church, which consists of 23 churches sui iuris, in full communion with the Bishop of Rome. The largest of these, the Latin Rite, consists of nearly 95% of the population of theCatholic Church. The remaining 5% consist of the 22 Eastern Catholic Churches.

Many Protestants sometimes use the term "Catholic Church" to refer broadly to the Christian Church and all believers in Jesus Christacross the world and the ages, regardless of denominational affiliation.^[7] [8] Generally, to avoid confusion between this concept and theCatholic Church, above, theologians (in English) will refer to the latter as the Church catholic, utilizing the lower-case.

The Eastern Orthodox, Oriental Orthodox, Anglicans, Lutherans and some Methodists believe that their churches are catholic in the sense that they are in continuity with the original universal church founded by the Apostles. The Roman Catholic, Eastern Orthodox, and Oriental Orthodox churches all believe that their church is the only original and universal church. In "Catholic Christendom" (including the Anglican Communion), bishops are considered the highest order of ministers within the Christian religion, as shepherds of unity in communion with the whole church and one another.^[9] Catholicity is considered one of Four Marks of the Church, the others being unity, sanctity, and apostolicity.^[10] according to the Nicene Creed of 381: "I believe in one holy catholic and apostolic Church."

Catholic Church

The Catholic Church, also known as the Roman Catholic Church, is the world's largest Christian church, claiming more than a billion members.^[1] It is a communion of 23 Churches under the Bishop of Rome -the Pope-, and it defines its mission as spreading the gospel of Jesus Christ, administering the sacraments and exercising charity.

The Catholic Church is among the oldest institutions in the world and has played a prominent role in the history of Western civilisation.^[2] It teaches that its bishops are the successors of Jesus Christ's apostles and that the Pope, as the successor ofSt. Peter, possesses a universal primacy.

Catholic doctrine maintains that the Church is infallible when it dogmatically teaches a doctrine of faith or morals.^{[3][4][note 1][5]}Catholic worship is centred on the Eucharist in which the Church teaches bread and wine are supernaturally transubstantiatedinto the body and blood of Christ.

The Church holds the Blessed Virgin Mary in special regard. Catholic beliefs concerning Mary include her Immaculate Conception without the stain of original sin and bodily Assumption into heaven at the end of her life.

Christianity

Christianity (from the Ancient Greek word Χριστός, Khristos, "Christ", literally "anointed one") is a monotheistic religion^[1] based on the life and teachings of Jesus as presented in canonical gospels and other New Testament writings.^[2] Adherents of the Christian faith are known as Christians.^[3]

Christianity teaches that Jesus is the Son of God, God having become human and the savior of humanity. Because of this, Christians commonly refer to Jesus as Christ or Messiah.^[4] The three largest groups in the world of Christianity are the Roman Catholic Church, the Eastern Orthodox churches, and the various churches of Protestantism. The Roman Catholic and Eastern Orthodox patriarchates split from one another in the East-West Schism of 1054 AD, and Protestantism came into existence during the Protestant Reformation of the 16th century, splitting from the Roman Catholic Church.^[5]

The word Christianity is the label that has been widely accepted by the secular and church-world to describe the practice of faith by the followers or disciples of Jesus Christ.

Christianity began as a Jewish sect in the mid-1st century.^[6][7] Originating in the eastern Mediterranean coast of the Middle East (modern Israel and Palestine), it quickly spread to Syria, Mesopotamia, Asia Minor and Egypt, it grew in size and influence over a few decades, and by the 4th century had become the dominant religion within the Roman Empire.^[8] During the Middle Ages, most of the remainder of Europe was Christianized, with Christians also being a sometimes large religious minority in the Middle East,North Africa, Ethiopia^[9] and parts of India.^[10] Following the Age of Discovery, through missionary work and colonization, Christianity spread to the Americas, Australasia, sub Saharan Africa and the rest of the world.

Christians believe that Jesus is the Messiah prophesied in the Hebrew Bible, referred to as the "Old Testament" in Christianity. The foundation of Christian theology is expressed in the early Christian ecumenical creeds, which contain claims predominantly accepted by followers of the Christian faith.^[11] These professions state that Jesus suffered, died, was buried, and wasresurrected from the dead to open heaven to those who believe in him and trust him for the remission of their sins (salvation).^[12]They further maintain that Jesus bodily ascended into heaven where he rules and reigns with God the Father. Mostdenominations teach that Jesus will return to judge all humans, living and dead, and grant eternal life to his followers. He is considered the model of a virtuous life, and both the revealer and physical incarnation of God.^[13] Christians call the message of Jesus Christ the Gospel ("good news") and hence refer to the earliest written accounts of his ministry as gospels.

As of the early 21st century, Christianity has around 2.2 billion adherents.^[14][15][16] Christianity represents about a quarter to a third of the world's population and is the world's largest religion.^[17] Christianity is the state religion of several countries.^[18]
