inexpensive netbook

half the weight of a netbook. This is not a lot of weight, but a hand holding a half-day is also tired (but you will be a hand holding the netbook for half a day?) ）。 But the industrial design and engineering departments are at their wits ' end. The weight of the iPad is a necessary tradeoff, limited by current technology and high density materials: if you want a LED backlight screen with optical glass,

Some netbook users are depressed because they can't install Windows 7 without a DVD drive. In fact, you do not have to be depressed, because we can install the Windows 7 system without the DVD drive, just need a 4GB-size USB flash drive, tested, using USB flash drive to install Windows 7 is faster than using DVD drive installation. Let's talk about the specific steps: 1. First we need to find a 4GB-size USB stick and plug it into the

for mobile devices such as mobile phones. Currently, a number of mobile phone and netbook manufacturers have launched a model based on the Android operating system. Google is one of the long-standing advocates of the industry's view that network computing will increasingly play a central role compared to the personal computer installation of applications. Google believes that in the future, applications will run directly in the Internet browser. La

Storage Management:Here we are going to learn about two types of disk arrays:The disk array is made up of many inexpensive disks , combined into a large-capacity disk group, the use of individual disks to provide data generated by the bonus effect to improve the overall disk system performance. Using this technique, the data is cut into many sections, which are stored on each hard drive. First, RAIDWhat 1.RAID is:Raid:redundant Arrays of

Raid:redundant Arrays of Inexpensive Disks, with "Redundant Array of Inexpensive disks" means. Abbreviated disk array.The disk array is made up of a lot less expensive Disk , combined into a large-capacity disk group, the use of individual disks to provide data generated by the bonus effect to improve the overall disk system performance.

Some time ago, I was asked what was cloud computing, and I explained it with some of my own ideas and some of the concepts I had accumulated, but I didn't feel very thorough about myself.Today, we specifically looked for some relevant information, summarized as follows:The concept of cloud computing:Professor Liu Peng Two definitions of the length of cloud computing.The long definition is: "cloud computing is a business computing model. It distributes computational tasks across a large pool of c

UbuntuLinux has numerous fans. Is there anything different? A free operating system with tens of thousands of free applications. The website covers everything you want to know, tutorials, and active forums. However, to achieve all these benefits, the solution jumps out when you need a faster and lighter operating system. Maybe you have an old computer or a netbook or mobile device. Isn't it better to have a lightweight Ubuntu? This day has finally arr
