Question Answer : Microsoft says Windows 7 is designed to run well on PCs that meet the recommended system requirements for Windows Vista. Before you upgrade to Windows 7, be sure to compare your PC's specifications with the Windows 7 system requirements as follows:. Answer : Most recent netbooks will be able to run Windows 7. However, it is yet unclear how Microsoft plans to deliver the update to machines without an optical drive.

The latest speculation on the matter suggests that Microsoft is considering selling Windows 7 on a USB drive. Alternatively, the company might partner with retailers and offer an in-store netbook upgrade program. Answer : Well, the price is a huge difference between the upgrade and full version.

Windows 7 upgrade is meant for those running Windows XP or Vista. In case, you are going for new system you could get the OEM version from the supplier cheaply. Clearly with the upgrade you get all the Windows 7 features. Then who would go for the full version. People running the age old Windows 98, or 95 need to buy the full version. Even those who want Windows 7 on a Mac computer using Boot Camp, or who are running Linux should go for it. The upgrade and the full discs are same.

It needs to be installed using a USB key. In case you can do with command lines. You might use the DIskpart utility. That's the only solution if you have a netbook without optical drives. Answer : There's is a huge confusion over the term Upgrade for Windows 7. The terms is used to describe the price variant as well as the term used in the installation process.

Now if you buy the Windows Upgrade, you will get the Upgrade and Custom options during the installation. The Upgrade version can only be opted if you are already running Vista. Choosing the Upgrade option carries your applications, documents, settings and user accounts over to the new OS. In case you are not coming from Vista, go for the Custom option which would ensure fresh installation. For the XP user who wanna migrate instead of wiping everything out and reinstalling, you can use Laplink's PCmover to get the same result as doing an Upgrade installation.

Remember even after custom installation your old filed will be preserved in a folder named Windows. Check out our Why Windows 7 article for a detailed explanation on the subject. Is This Answer Correct?

The testing period for Micrsoft Windows 7 is now over. Microsoft will release six editions of Windows 7 but concentrate marketing efforts on two of them. The Windows 7 pre-order deal is available only online. In the U. Both special prices upgrades are available for Windows XP and Vista users. Windows XP users will have to do a clean install. Moving from a bit version of Windows to a bit one will require a clean install as well.

Microsoft says Windows 7 is designed to run well on PCs that meet the recommended system requirements for Windows Vista.

FCFS stands for First-come, first-served. It is one type of scheduling algorithm. Implementation is managed by a FIFO queue. RR round-robin scheduling algorithm is primarily aimed for time-sharing systems.

A circular queue is a setup in such a way that the CPU scheduler goes around that queue, allocating CPU to each process for a time interval of up to around 10 to milliseconds. Deadlock situations occur when four conditions occur simultaneously in a system: Mutual exclusion; Hold and Wait; No preemption; and Circular wait.

It gets its name from a banking system wherein the bank never allocates available cash in such a way that it can no longer satisfy the needs of all of its customers. One is that it depends on how often a deadlock is likely to occur under the implementation of this algorithm.

The other has to do with how many processes will be affected by deadlock when this algorithm is applied. Logical address refers to the address that is generated by the CPU. On the other hand, physical address refers to the address that is seen by the memory unit. With dynamic loading, a routine is not loaded until it is called.

This method is especially useful when large amounts of code are needed in order to handle infrequently occurring cases such as error routines. Overlays are used to enable a process to be larger than the amount of memory allocated to it.

The basic idea of this is that only instructions and data that are needed at any given time are kept in memory. Paging is a memory management scheme that permits the physical address space of a process to be noncontiguous.

It avoids the considerable problem of having to fit varied sized memory chunks onto the backing store. Fragmentation is memory wasted. It can be internal if we are dealing with systems that have fixed-sized allocation units, or external if we are dealing with systems that have variable-sized allocation units.

During regular intervals that are set by the operating system, processes can be copied from main memory to a backing store, and then copied back later. Swapping allows more operations to be run that can fit into memory at one time. A socket provides a connection between two applications.

Each endpoint of a communication is a socket. Direct Access method is based on a disk model of a file, such that it is viewed as a numbered sequence of blocks or records. It allows arbitrary blocks to be read or written.

Direct access is advantageous when accessing large amounts of information. Thrashing refers to an instance of high paging activity.

This happens when it is spending more time paging instead of executing. The best paging size varies from system to system, so there is no single best when it comes to page size. There are different factors to consider in order to come up with a suitable page size, such as page table, paging time, and its effect on the overall efficiency of the operating system.

Typically, the different attributes for a file structure are naming, identifier, supported file types, and location for the files, size, and level of protection.

Root partition is where the operating system kernel is located. It also contains other potentially important system files that are mounted during boot time. This prevents conflicts whenever such devices are incorporated in a systems unit. Linux is also more secured than Windows and it is difficult to hack into a Linux system. The command-line centered Linux systems make it difficult for normal users to use it.

Windows Windows is a proprietary OS developed by Microsoft which users need to pay to use it. Windows is a closed-source operating system that offers very little customization than Linux. It is also less efficient than Linux in handling resources with less security. The easy to use interface offered by Windows makes it a preferred choice of the operating system by most of the users.
