WINDOWS 8.1 TELAH DIRILIS

start screen pada windows 8.1

Microsoft telah mengumumkan update terbaru yaitu

Windows 8.1 yang merupakan free update bagi pengguna windows 8

Berikut adalah beberapa perubahan dan penambahan fitur-fitur pada windows 8.1.

Kembalinya tombol Start

Sebelum Windows 8 diluncurkan, para pengguna dapat dengan mudah membuka aplikasi, mencari fitur Control Panel, hingga mematikan PC. Hal tersebut disebabkan semua fitur dijejali oleh Microsoft ke dalam sebuah tombol, yaitu Start.

Maka, tidak heran apabila pengguna lama Windows kesulitan setelah menyadari bahwa Windows 8 sudah tidak lagi hadir dengan tombol Start. Untuk melihat aplikasi yang ada, pengguna harus masuk ke tampilan Metro, sedangkan tombol menu Control Panel dan tombol Shutdown disatukan ke sebuah tempat yang dinamakan Charm Bar.

Setelah banyak menerima keluhan terkait tombol ini, Microsoft akhirnya mengembalikan tombol "Start" tersebut ke Windows 8.1. Namun, fungsinya sedikit berbeda dibandingkan dengan OS generasi sebelumnya. Tombol "baru" ini sebenarnya hanya menampilkan Start Screen ala Metro ketika diklik. 

Tidak ingin menampilkan tampilan Metro ketika tombol ini diklik? Dengan sebuah pengaturan, pengguna dapat mengubah tampilan menjadi "All Apps" untuk mengembalikan cara kerja tombol Start tradisional.

Pengguna pun bisa mengakses beberapa menu lain, seperti Task Manager, Control Panel, Search, dan Run. Caranya adalah dengan mengklik kanan tombol Start, secara otomatis menu-menu tersebut akan ditampilkan.

Lock Screen yang lebih keren 

Layar Lock di Windows 8.1 tidak tampil monoton. Layar ini tampil lebih interaktif dari Windows 8. Pengguna bisa memasang slideshow foto, menerima panggilan Skype, dan mengakses kamera langsung dari layar tersebut.

Kustomisasi secara bebas

Microsoft mengizinkan kustomisasi yang lebih banyak ke para pengguna. Salah satu contoh kustomisasi tersebut adalah pengguna kini dapat menyamakan wallpaper tampilan desktop dan tampilan Metro. Fitur ini membuat pengguna tidak akan terlalu kebingungan apabila ingin berpindah dari desktop ke Start Screen.

Pengguna tetap dapat mengubah ukuran kotak yang ada di tampilan Metro. Namun, caranya sedikit berbeda. Untuk mengubah dan memindahkan kotak-kotak aplikasi, pengguna harus menahannya terlebih dahulu. Hal tersebut terlihat kurang intuitif, tetapi ini dapat mencegah pergerakan atau perubahan ukuran kotak secara tidak sengaja.

Perubahan fitur Search

Fitur Search di Windows 8.1 hadir lebih menarik. Sistem akan mencari semua hal yang berkaitan dengan kata-kata yang ingin dicari oleh pengguna. Sistem melakukan pencarian dari hard drive yang ada di PC dan situs. Contohnya, apabila pengguna mengetik kata "Kompas", maka sistem akan mencari file yang berkaitan dengan kata tersebut di PC dan juga internet.

Melalui fitur ini, pengguna juga bisa langsung menjalankan aplikasi. Caranya, ketikkan beberapa huruf nama software, maka akan muncul daftar hasil pencarian. Klik saja nama aplikasi yang diinginkan, maka sistem secara otomatis akan menjalankan software ini.

Windows 8.1 bisa jalankan empat aplikasi bersamaan 

Multitasking merupakan fitur yang sudah ada di Windows sejak dulu. Microsoft meningkatkan kemampuan tersebut di Windows 8.1. Pengguna dapat menjalankan empat aplikasi sekaligus dalam sebuah layar terpisah.

Namun, fitur ini sangat bergantung pada ukuran layar. Contohnya, apabila pengguna menggunakan layar monitor 27 inci, sistem bisa menampilkan empat aplikasi tersebut dengan sangat baik. Apabila menggunakan tablet 8 inci, sistem hanya mampu menampilkan 2 window aplikasi saja. 

Aplikasi di-"update" secara otomatis

Aplikasi yang diunduh dari toko aplikasi Microsoft akan langsung diperbarui apabila pihak pengembang merilis versi barunya.

"Boot" langsung ke tampilan "desktop" klasik

Di Windows 8, saat PC boot-up, pengguna akan langsung dibawa ke tampilan Metro. Nah, di OS baru ini, pengguna bisa mengatur, pada saat boot-up, sistem membawa mereka ke tampilan desktop.

Caranya pun cukup mudah. Di tampilan desktop, klik kanan di task bar, kemudian pilih "Go to the desktop instead of Start when I sign in".

A Little History of the G Mobile Generations

    

   It would be heedless to say that we haven’t come a long way as far as mobile technology is concerned.  The first cell phones could barely keep a call connected let alone send a text message and now we are streaming content across the wireless spectrum while cruising the web and talking to friends.  A long way indeed.  Where does it go from here and will the wireless spectrum stand up to the test? We will soon find 

out.

2G Rises to the Challenge

       When smart phones were first introduced, there was no texting as well as undoubtedly horrible connections. Then came 2G or 2nd Generation networks as well as by having them came the capability to transfer and get information, although the velocities were actually sluggish - 9.6 kb|s - slower than the old, screechy, modems that we used to utilize in the early days of the Internet. Slowly technological innovation strengthened and information rates were raised, by having the latter types of 2G getting to speeds of about 56kb|s and we thought that was fast!

3G is Introduced

      3G or the 3rd Generation of mobile technology innovations took us by storm with speeds of about 4 times quicker than the old 2G standards. With initial speeds of around 200kb|s and steady transformation of the technological innovations saw maximum speeds of up to  7.2 Mb|s and we were awed by the things that could be accomplished. The latter speeds were just numbers because the highest rates were not achievable unless you were in the right spot at the right time.  Still quite an improvement.

Currently 4th Generation technologies are being presented around the world and devices are being made available that may enjoy this brand-new mobile advancement in speeds and reliability.

However exactly what is 4G?

      4G or the 4th Generation Mobile standards is a series of measures that defines the demands of a 4G network and also the standards that must be met. The existing common standard specifies a 4G network as one that offers 100Mb|s for individuals on the move as well as which supplies 1Gb|s to an immobile location or one shifting at a slow-moving speed, or standing still in that perfect spot for instance.  There are many variable involved that profusely degenerates the speed that you will actually be capable of utilizing.

Yes there are 4G devices available that can take advantage of the high speed networks being built but that network has a long way to go before most of us realize the true potential.  The term 4G is being thrown around a lot but true 4G is not widely recognized.  4G is faster than 3G but it has to meet the specifications of the standards to be called true 4G.  When we start hearing the buzzword 5G, LTE-Advanced or WiMAX Release X, then we will probably be using more of a True Fourth Generation mobile technology.  Oh, those marketing people are good at spinning stuff though aren’t they?

Technology is systematic, purposeful manipulation of the material world. It is a process: power is applied through a tool or machine to a certain material by employing a certain technique. The result is an artifact. The term technology, meaning the study of technics, appeared in the seventeenth century; before then, all was arts and crafts, passed on by apprenticeship.

Until modern times, the artifacts of war were built on a human scale, powered by muscle. By about 10,000 b.c., the major weapons of premodern warfare had appeared--the spear, sling, mace, knife or short sword, and finally the bow and arrow, arguably the first machine. These deadly instruments prompted development of defensive technologies, first body armor and then fortification, the most important military technology before gunpowder. Walls precluded many wars and channeled the course of others.

There was a symmetry to the weapons employed in most wars fought before the modern era. The two sides deployed similar arms and armor. In such circumstances, the outcome was usually determined by strength in numbers, the fighting prowess of the combatants, or superior tactics, strategy, or leadership. Occasionally one side or another enjoyed a technological advantage, as did the chariot empires of the second millennium b.c. And occasionally arms races dominated, such as that between fortress building and siege techniques in the first millennium b.c. But there is no reliable evidence for secret military technologies in the ancient, medieval, or classical worlds, save Greek fire in the middle centuries of the Byzantine Empire; winning weapons were available to all.

Throughout the period when muscles powered war, weapons fell in two broad categories: missile and striking. Generally, missile weapons, such as the bow and arrow and the thrown spear, were the choice of mobile warriors, often mounted nomads and raiders such as the Scythians of Roman times. They used speed and surprise to throw the enemy off balance and inflict casualties without the risk of a toe-to-toe engagement. Striking weapons such as the sword, the mace, and the stabbing spear were the choice of infantry, who relied on discipline, formation, and mass to overpower and annihilate their enemy, as did the Spartans of classical Greece. The choice of weapons in such cases reflected deep-seated societal convictions about the nature of war and its role in society: a standing, professional army bent on offensive war might choose one set of weapons, whereas an amateur militia defending its homeland might prefer another. The weapons of choice also had to be appropriate to the context; cavalry, for example, was suited to the grassy steppes of Eurasia but not to the barren mountains of the Greek peninsula.

The gunpowder revolution that began in the West in the fourteenth century transformed warfare. Strength and skill gave way to machines. For the first time in the history of land warfare, equipment mattered more than men. On the battlefield of the late Middle Ages, for example, an uneducated, poorly trained, and uninspired gunman could bring down a mounted knight, the flower of European chivalry and the uncontested champion of the feudal battlefield. What is more, larger versions of these same gunpowder weapons, when turned on fortress walls, could reduce the refuge to which the mounted knight had retired when faced with superior force and to which peaceful societies had turned throughout history when beset by predator bands. The muscle that had wielded the sword and raised the fortress wall gave way to the chemical power of the internal combustion engine, which powered the cannon. From there to the hydrogen bomb, it was a straight line.

Gunpowder weapons also transformed naval warfare. War at sea, since it first appeared in the second millenniumb.c., has always been more technological than warfare on land. The ship, often the most complex artifact of its age, is a necessary precondition of this combat; it furthermore determines what the combat will look like. Throughout most of history, this combat involved oared vessels--galleys--which sometimes rammed each other but more often locked up in deadly embrace to support hand-to-hand fighting by marines. Unsuited to gunpowder weapons, the galley gave way in the sixteenth century to the European broadside-firing sailing vessel, which established Western hegemony over the world's littoral. This warship was in turn displaced in the middle of the nineteenth century by vessels incorporating steam propulsion, screw propellers, armor, rifled guns, and high explosives. These set off anarms race that spread in the twentieth century from battleships to submarines and aircraft carriers.

The Industrial Revolution that transformed naval warfare effected similar changes on land. From the American Civil War through World War II, the great powers fought wars of industrial production. Often, the total resources of the state were mobilized; productive capacity, not battle, became decisive. The target of combat expanded accordingly, from the army in the field to the entire economic and industrial base of the enemy, including transportation, utilities, natural resources, and capital equipment.

World War II was the first war in history in which important weapons in use at the end had not existed when the war broke out. Jet aircraft, ballistic missiles, proximity fuses, and the atomic bomb were all invented and fielded in a frenzy of research and development. Since 1945, the quality of military technology has replaced quantity as the desideratum of modern war. The electromagnetic spectrum has become the most important locus of new military technologies, ranging from remote sensing devices and information technology to precision guided munitions and satellite-based navigation. The competition to prevail on this electronic battlefield has produced an international arms race, military-industrial complexes in the United States and elsewhere, an unprecedented prominence for the military as a driver of civilian technology, and finally a search for dual-use technology that can serve both military and civilian purposes.

Nowhere are these phenomena more evident than in aerospace technology, the third dimension of warfare. A product of the twentieth century, air warfare, like naval warfare, is entirely dependent on technology. From the Battle of Britain in 1940 to the Gulf War of 1991, quality has consistently proved superior to quantity. Research and development drive the field and ensure that only the wealthiest, most technologically advanced states can be truly competitive. This same phenomenon is true in the latest arena of military technology--outer space.
