Một danh sách các ứng dụng bởi người dùng hiện tại mở. Bạn có thể đóng một ứng dụng bằng cách nhấp chuột vào nó và sau đó nhấp vào End Task. Nếu menu Start không hoạt động, bạn có thể bắt đầu một ứng dụng mới bằng cách nhấn vào New Task. | Task Manager has six tabs Applications A list of applications open by the current user. You can close an application by clicking it and then clicking End Task. If the Start menu is not working you can start a new application by clicking New Task. If the Windows Explorer interface is not open you can click New Task and then run Windows Explorer to open it. Processes A list of processes open by the current user. You can view processes open by all users by clicking Show Processes From All Users. You can quickly identify the process that is using the most processor time by clicking the CPU column header to sort the processes by processor utilization. To end a process select the process and then click End Process. Ending a process is particularly useful when a non-responsive application is consuming all the processor time and slowing the computer down. Services Lists all the services on the computer running or stopped. You can start and stop services by right-clicking the service. This tab provides similar functionality to the Services console but with the convenience of Task Manager. Performance Shows current processor and memory utilization. If a computer seems slow open the Performance tab to determine whether processor or memory utilization is causing the problem. If processor utilization is causing the problem one or more of the processors in the CPU Usage History chart will be at 100 as the first processor is in Figure 8-5. If memory utilization is causing the problem the value shown in the Memory chart will be close to the Total value shown in the Physical Memory group. FIGURE 8-5 Task Manager shows processor and memory utilization. Networking Charts the network utilization of each network interface. Use this tab to determine whether a slow network might be caused by an application using all the available bandwidth. Wired network connections typically do not support more than 70 utilization therefore a wired network at 65 utilization can be considered 316 CHAPTER
