Windows 8 Is the code name for the next version of Microsoft Windows, a series of operating systems produced by Microsoft for use on a PC, including home computers and business computers, laptops, netbooks, tablet PCs, and computer media. Microsoft also called app-store will launch a version of Windows. App-store include Metro-style app for Windows 8 or Windows Classic.
Here are some pictures to see Windows 8, as taken from Tech land:
Apart from that, there are some advantages and disadvantages of Windows 8. Here's the explanation
Advantages:
1. Form a More Dynamic
Just like cell phones (mobile phones) smartphones and tablets, computers using the Windows 8 operating system comes with a notification feature and the current information, regarding your account in cyberspace. For example, the inbox electronic mail (e-mail). In addition you will also automatically connect to the data storage site belonging to Windows, Skydrive.
2. More Universal Data Search System
With Windows 8, you are easier to find the desired data. Simply type the name of the data in the initial display, directly several options related data.
3. Availability and Ease of Application Support
You have a lot of choice and convenience to get Application support if your computer uses Windows 8 operating system.
Deficiency:
1. No Start button and Close X
Unfortunately, there is no start button and Close X on the display face of Windows 8. This makes users confused and difficult to start the work, closing the job or accessing the program. Although the data search system, but the presence of the Start button is considered very important for the convenience of users.
To end the task in Windows 8, you must direct your mouse arrow to the top of the application. After emerging-hand button, you have to drag it, and then the program is closed.
2. Many Hidden Files Or Apps
This is probably the most confusing for users of Windows 8. Therefore, during operation, are only two data or applications that can be open simultaneously, while other data is hidden. You must use the universal search feature to open another data.
For your information, Windows 8 will be marketed at a price range of 69.99 US dollars. As of the end of January 2013, customers who are currently running a PC with Windows XP, Windows Vista or Windows 7, has the right to download (download) Windows 8 Pro with an estimated retail price of 39.99 US dollars.
A. Operating System Windows 8
Windows 8 is the name of the latest version of Microsoft Windows, a series of Microsoft which is produced by Microsoft for use on personal computers, including home and business computers, laptops, netbooks, tablets, PCs, servers and media center PCs. This operating system using the ARM microprocessor in addition to a traditional x 86 microprocessor artificial intelligence and AMD. Change user interface in order to be used on touch-screen devices other than the mouse and keyboard, so that Windows 8 is designed for touch tablet device.
B. Disadvantages windows 8
- Button star and close enough so there is no confusion for the user to make the new windows 8
- File and hidden applications so as to open a file must use the universal search feature.
- The overlapping succession continue to occur that occur between the tile-based Metro U I and glassy Aer o U I
- Lack of options to change the tiles to be icons
- It is difficult to move between screens, which we usually use the functionality of Alt + Tab to switch screens and applications
- Windows 8 does not support flash Content and Microsoft was deliberately doing this to save battery life and maintain security and stability
C. Management Files In Windows 8 Operating System
File management is part of the operating system to organize and keep trace files. File management is important because it can reduce the risk of lost files due to accidentally erased, hit a new file, stored in an unknown location and other things that are not desirable.
It branded center of the system The window in the put on Drive C, or in Windows Explorer is the default naming Local Disk [C:] for the directory that is the main file of the Windows system installed or stored. Besides Drive [C:], on the windows there are also other drives such as drive [A:], [D:], [E:], [F:], and so on. Although the drive [C:] is the central control system, but Microsoft make it parallel to Drive the other example like Drive [D:] that are usually used as data storage or a second partition on the hard drive and then drive [E:] for CD-Drive and drive [F:] to stick.
Windows Explorer is a tool in the management of files in general, to open and save files or to access certain parts of the Windows shell such as the Control Panel. Windows Explorer may Custom to show or hide some elements of the navigation and look and can also Custom based display configuration and layout of the column.
- Here are some of the functionality in the 'File Explorer'.
- Move to: function to move the file to another folder, or move the folder to another.
- Copy to: function to duplicate the files contained in a folder to another folder.
- Delete: serves to delete files or folders contained in the library.
- New folder: function to create a new folder in the library.
D. Process Scheduling in Windows 8
Windows 8 using a Round Robin algorithm, this algorithm cycle processes in the queue. The process will receive rations of time quantum. If the time quantum is exhausted or the process is complete, the CPU will be allocated to the next process. Of course this process is fair enough because there is no priority process, all the process gets the same time of the CPU is (1 / n), and it will not wait longer than (n-1) q with q is a long one quantum.
This algorithm is entirely dependent amount of time quantum. If it is too big, this algorithm would be tantamount to an algorithm first come first served. If it is too small, the more the transition process so much time wasted.
The main problem in the Round Robin is determining the time quantum. If the specified time quantum is too small, then most of the process will not be completed in one quantum. This is not good because there will be a lot of switches, when the CPU requires time to switch from one process to another process (referred to as context switches time). Conversely, if the time quantum is too large, the algorithm will run like Round Robin algorithm is first come first served. Time quantum ideal is if 80% of the total process has a CPU burst time smaller than 1 time quantum.
Multilevel Feedback Queue Scheduling
These algorithms allow the process to move the queue. If a process is seized CPU too long, the process will be moved to a lower queue. This is beneficial interaction process because this process only uses a little CPU time. Similarly, the process of waiting too long. This process will be increased levels. The highest priority is usually given to the process with the smallest CPU burst, so the CPU will fertilization full and I / O can be kept busy. The lower the level, the CPU burst length of the process is also getting bigger.
E. Synchronization and Dead look
Is the basis of Multi programming, multiprocessing, and distribute processing. competition solve the problem if there are a lot of programs, as in the previous algorithm only cope with one process. When many processes are in the same time, then when that's called concurrent. The problems occur when there are concurrent processes are:
a. Synchronization
The process of setting the course of several processes at the same time. Means an outline of possible synchronization is evened things together.
b. Dead Lock
The circumstances in which the two programs were gaining control over the resources needed by other programs. No one can continue the process of each other until the program provides resources, but no budge. Deadlocks that may occur in a process due to the process of waiting for a particular event that will never happen. Two or more processes are said to be in a deadlock condition when any process that is waiting for an event that can only be done by another process in the set.
That's needed scheduler order to avoid these problems. Windows 8 uses UM S (User-mode Scheduling). UM S is a mechanism that enables an application to be used to schedule thread own. Threads can be defined as an entity of the process, which is the scheduled execution time by the operating system.
