 Operating system (OS)

in this week we had a debate on explaining how between wired internet connection and wireless which one is better.i was supporting wireless is better reason being wireless facilitate mobility means that you can access internet on the go for instance mobile we use everyday can be a good example.the debate ended in 30 minutes and my side won one of the example that made us win this debate is this example given by one student:-if there was no wireless people to make a call there should need long cables. this was the point that was not easy to answer for the opponent group.

after debate we studied week five lesson:Operating system

Microsoft released a number of Windows operating systems ranging from Windows xx, NT, Server from 1985 till now. The latest is Windows 8. Microsoft created the operating system, Windows, in the mid-1980s. They have a version of the operating system that is designed for the home user, and a professional version, which is intended for businesses. The versions differ in the depth of networking, security, and multimedia support.

Windows is proprietary software, which means that Microsoft has placed restrictions on how people can use or copy the software. Windows comes preloaded on most of the PCs sold today, and can also be purchased separately.

Windows aims.

                                       Decrease Start Up and Shutdown times by 20 secs

                                       Go to Sleep and Resume faster

                                       Use up less Memory

                                       Pop up Search results faster

                                       Reconnect to your Wireless Network more quickly

                                       Recognize USB devices faster

Windows 7 also saves time by not booting up various devices during Start Up unless they are currently being used. In other words, if you are not using a Bluetooth device at the moment then Windows 7 will not waste time by running that program in the background. It will wait until you have plugged it in. However, performance tests of Windows 7 indicate that actual improvements vary and greatly depend on the conditions of your specific computer and the programs you are running. We will go into more detail regarding your computer's ability to run Windows 7 in future lessons
We’ve seen that windows seven has new upgrades from vista and Xp such as :

• New Taskbar and System Tray
• Quick Desktop View button
• Improved Start Up, Sleep and Resume performance
• Improved power management saves memory and battery life
• Libraries to improve file access and organization

Windows7 File Management

The Windows 7 environment is not an extension of XP; it’s an entirely new interface. Although the underlying file structure is the same, there’s less to file management compare to XP. Windows 7 doesn’t require the knowledge of storing and accessing files as in XP and earlier versions — the file hierarchy is behind the scenes. Windows 7 is in fact easier to use, but you need to be acquainted with it.

Finding Files and Folders

Most users access their files through "My Documents", the "C" drive, or from other locations like a server or back up drive. You are likely accustomed to sorting through tiered stacks of folders to get to your content. This process can be time consuming, especially if you cannot remember where an item is filed. Microsoft wanted to make "finding your stuff" easier, so they developed Libraries.

   

Libraries are collections of your stored content that can be easily accessed through the Desktop Search function. Libraries do not replace your folders, they simply house them in a single collection.

When files are placed in a Library, their properties are indexed by the Search function. This indexing makes accessing files in Search quick and easy.

A New Approach to Accessing Content

Libraries have automatic default save folders. Unless specified, your content will be saved in the default folder of the Library it matches.You can change the default save folder by selecting Locations in the Tool Bar.You are not required to save or access your content through Libraries. The Navigation pane gives you access to Computer where your folders and drives are stored. You may still sort through the tiered stacks of folders in the classic way to save and access content.
