"State specification or special features of one hardware and compare it to previous model?"
How do you reallocate unpartition drive?
To reallocate the space of an unpartitioned drive, one should create a partition(s) from it. This is best done when installing the computer's operating system.
How do you replace the soft power switch on the front of your PC?
There are usually a couple of small screws on either side of the switch. You'll have to take the side cover(s) and front cover off.
You will need to trace the wires from the switch and notice where they are plugged into the motherboard. There is most of the time a triangle on the plug that connects to the motherboard, that triangle needs to line up with pin one of the "jack" on the motherboard. On some motherboards that matters, on others it doesn't.
It isn't that hard, and there's no danger. The biggest problem is some systems are really cramped, and you have to be able to trace the wires.

In 60 BC, Caesar entered into a political alliance with Crassus and Pompey that was to dominate Roman politics for several years. Their attempts to amass power through populist tactics were opposed within the Roman Senate by the conservative elite, among them Cato the Younger with the frequent support of Cicero. Caesar's conquest of Gaul, completed by 51 BC, extended Rome's territory to the English Channel and the Rhine. Caesar became the first Roman general to cross both when he built a bridge across the Rhine and conducted the first invasion of Britain. These achievements granted him unmatched military power and threatened to eclipse Pompey's standing. The balance of power was further upset by the death of Crassus in 53 BC. Political realignments in Rome finally led to a standoff between Caesar and Pompey, the latter having taken up the cause of the Senate. Ordered by the senate to stand trial in Rome for various charges, Caesar marched from Gaul to Italy with his legions, crossing the Rubicon in 49 BC. This sparked a civil war from which he emerged as the unrivaled leader of the Roman world.
After assuming control of government, he began extensive reforms of Roman society and government. He centralised the bureaucracy of the Republic and was eventually proclaimed "dictator in perpetuity". A group of senators, led by Marcus Junius Brutus, assassinated the dictator on the Ides of March (15 March) 44 BC, hoping to restore the constitutional government of the Republic. However, the result was a series of civil wars, which ultimately led to the establishment of the permanent Roman Empire by Caesar's adopted heir Octavius (later known as Augustus). Much of Caesar's life is known from his own accounts of his military campaigns, and other contemporary sources, mainly the letters and speeches of Cicero and the historical writings of Sallust. The later biographies of Caesar by Suetonius and Plutarch are also major sources.
Is friction good for machines?
Some machines need friction to operate. Brakes, grinders, traction wheels, and others all rely on friction to work. In other cases, friction is bad. electric and fuel-fired powerplants for example, are all designed so as to minimize friction. That's why the lubricant industry exists!

solo daré siete pequeños tips.
1. Comprueba los programas ejecutándose. Aprieta en control + alt + suprimir, ve a la pestaña de "procesos" y comprueba qué está ejecutándose. A veces el PC va lento porque se están ejecutando muchas aplicaciones a la vez y puede que tenga poca RAM. Termina los procesos que no necesitas.
2. Elimina virus y troyanos. Si han entrado virus, troyanos o spyware en tu PC en alguna ocasión, es probable que pueda volver a suceder. Consigue un buen antivirus, haz un análisis y elimina o pon en cuarenta las infecciones.
3. Aumenta la RAM. Muchos ordenadores se compraron cuando se inició el negocio y desde entonces no han vuelto a actualizarse. Si crees que no es necesario invertir en nuevos PC, al menos deberías aumentar la RAM.
4. No trabajes con programas muy pesados. Si tu ordenador no está preparado para soportar la ejecución de determinados programas, como por ejemplo de vídeo, puedes hacer varias cosas. Cambiar tu tarjeta de vídeo y aumentar la RAM, o bien buscar otro software más adaptado al hardware que tienes.
5. Limpia tu navegador de basura. Muchas veces lo que afecta al rendimiento del PC no es sino los plugins que se han instalado en el navegador, en ocasiones bastante peligrosos y en otras simplemente molestos. Si no estás seguro de los "toolbars" que te has descargado, entre en Herramientas > Complementos de Firefox, o en los plugins de Google Chrome, y elimina lo que no necesites.
6. Usa un sistema operativo menos pesado. Trabajar con Windows Vista puede ser extraordinariamente incómodo en algunos PC. Si tienes ordenadores con este SO y 1GB de RAM, es mejor actualizarse a Windows 7, o incluso volver a XP, que ocupaba menos.
7. Vacía tu PC. Si estás cubriendo todo el espacio disponible en disco duro, te estará sacando carteles informativos de que no hay espacio en la memoria. Si tienes problemas para guardar archivos,
Wireless Fidelity.
Edit:
Wrong.
Wi-Fi doesn't mean anything. It was simply a clever name made to brand a product.
Some people simply added the idea of "Wireless Fidelity" during the developmental stages because they couldn't comprehend such a acronym-like name without a literal meaning.
That tagged phrase "Wireless Fidelity" was dropped soon after.
