New features[edit] Service Packs[edit] Service Pack 1[edit] System requirements[edit] Memory. Operating system. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.
Types of operating systems Single- and multi-tasking Single- and multi-user Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem.[6] A multi-user operating system extends the basic concept of multi-tasking with facilities that identify processes and resources, such as disk space, belonging to multiple users, and the system permits multiple users to interact with the system at the same time.

By effectively controlling millions of unsuspecting user PC's, modern botnets have demonstrated the ability to manage a global infrastructure on an unimaginable scale. By applying the same techniques and approaches used in botnets within your computing environment you'll be capable of handling any demands placed on you or your infrastructure. This how-to article will take a closer look at using common open source components to create your very own botnet for the purposes for securing, protecting, load testing and managing your global internet infrastructure.

A computer network can also consist of, and is usually made for, more than two computers: The primary purpose of a computer network is to share resources: You can play a CD music from one computer while sitting on another computer You may have a computer that doesn’t have a DVD or BluRay (BD) player. In this case, you can place a movie disc (DVD or BD) on the computer that has the player, and then view the movie on a computer that lacks the player You may have a computer with a CD/DVD/BD writer or a backup system but the other computer(s) doesn’t (don't) have it. Based on their layout (not the physical but the imagined layout, also referred to as topology), there are various types of networks. In a peer-to-peer network, each computer holds its files and resources.

Why Drives Fail" A hard drive is a mechanical device with several moving parts. Magnetic platters store the data itself, while a motorized spindle spins the platters.
A read/write arm moves across the platters, retrieving information or putting down new data. The arm is moved by an actuator, and the read/write heads themselves hover an infinitesimal distance above the platters. The distance is so small that a single piece of dust can get in the way. If any of the hard drive's mechanical parts fails, the whole drive will fail. The parts operate with incredible precision, so hard drives are rather fragile. Other mechanical failures can be both a curse and a blessing. The failure might be non-mechanical. There's one last area where a drive can fail, and it's particularly insidious because the drive actually didn't fail at all -- the drive's connection to your computer failed. The next section will describe the warning signs of impending hard drive failure.
