Background Intelligent Transfer Service (BITS)

After determining which updates it needs, the client imitates a download using the Background Intelligent Transfer service (BITS). BITS are an HTTP-based file transfer service that downloads files using only the network's idle bandwidth. This enables Windows Update to perform downloads without affecting other applications that are using the network. BITS downloads are also resumable in the event they are interrupted. BITS uses whatever idle network bandwidth is available when performing downloads, but it will not imitate a connection on a computer that uses dial-up access to the Internet. In this case, the download process will not start until the user initiates a network connection.

Baseline

Baseline is a set of readings, captured under normal operating conditions, which you can save and compare to readings taken at a later time. By comparing the baseline readings to the workstation's current ridings at regular intervals, you might detect trends that eventually affect the computer's performance. (306)

Channel

When you expand the Application and Services Logs folder, you see logs for Windows applications, such as Internet Explorer. When you expand the Microsoft and Windows folders, you see a long list of Windows components. Each of these components has its own separate log, called a channel

Collector

Subscriptions enable administrators to receive events from other computers (called sources) in the Event Viewer console on their own computers (called collectors)

Data Collector set

What a Data Collector Set does is capture multiple statistics and save them into a permanent record. Furthermore, the Performance Monitor provides a tailor-made report structure so that we can review these logs. Sets can contain readings from Performance counters, Event trace data, System configuration information and even registry values. These Sets also combine the old Alert feature of Performance Monitor. All you need to do is experiment with different thresholds and rules for scheduling data collection. Another useful troubleshooting tactic is to run WMI (Windows Management Interface) tasks after the Data Collector finishes.

Events

Primary function of the Windows Eventing engine is to record information about system activates as they occur and package that information in individual units called events. The application you use to view the MMC snap-in called Event Viewer

Hotfix

An update consisting of one or more files designed to address a specific problem or issue with operating system. Some hotfixes are intended for all windows users, and are released using the Microsoft Update web site, while others are intended for special circumstances and are released only to users experiencing a particular problem

Instance

An element representing a specific occurrence of the selected performance counter. For example, on a computer with two network interface adapters, each counter in the Network Interface performance object would have two instances, one for each adapter, enabling you to track the performance of the two adapters individually. Some counters also have instances such as Total or Average, enabling you to track the performance of all instances combined or the median value of all instances.

Performance Counter

Performance Monitor is a tool that can display information for hundreds of different statistics (called performance counters) in a variety of ways. You can use Performance Monitor to create a customized graph or report containing any statics you choose.

Performance object

A category representing a specific hardware or software component in the computer. Click the down arrow on a performance object to display a selection of performance counters related to that component

ReadyRoost

ReadyBoost is a Windows 7 feature that enables you to use the storage space on a USB flash drive to free up system memory for other uses

SuperFetch

SuperFetch is a caching routine that enables Windows 7 to restore user access to applications much faster than Windows XP. All of the Windows operating system uses a virtual memory management technique called paging. File on the hard disk. This increases the memory capacity of the computer, but it also slows down some processes because hard disks transfer data much slower than memory chips. Super Fetch addresses this problem by storing copies of your most frequently used applications in a cache in system memory. With this information in cache memory, the system can recall it almost instantaneously when you try to start working at your idle computer again.

Windows Experience Index

The system control panel contains a system rating called the Windows Experience Index, which quantifies the capabilities of a Windows 7 computer by breaking it down into categories and assigning each one a rating. One key function of this rating is to help users determine why a particular computer is unable to run the Windows Aero user experience. However the underlying technology of this tool has other uses as well. View detailed information that Windows 7 used to determine the system's overall rating.

Windows Server Update Service (WSUS)

A solution to both having each computer download the same updates independently compounds the amount of Internet bandwidth the system utilize and giving administrators opportunity to wait or test the new installation. WSUS is a program that downloads updates from the Microsoft Update Web site and stores them for administrative evaluation. An administrator can then select the updates to deploy and computers on the network download them using a reconfigured Windows Update client. The result is that WSUS server downloads each update from the Internet only once and then distributes it to the other computers using internal local area network (LAN) bandwidth.
