What are positive features of windows OS?
Compatibility, wide-spread use, and video games. Other than that, Linux or apple are more stable and usually faster on the same hardware. (don't know about new apple o/s's though.
Hello!
I'm never one for pitching a laptop until all reasonable efforts are made to locate the issue.
So, I researched your issue and it seems that you may need an update to the BIOS ("basic input/output system" which is the hardware and internal software that is responsible for booting the system). OR you may have a bad 'stick' of RAM.
First try this:
When the computer is totally off, press the power switch and hold it down for 4 seconds and then let go.
If the laptop powers up and windows starts to load normally you may need an update to your bios/firmware.
If your computer does start normally, you can check the version of your BIOS by using the following steps:
To find your current BIOS version in Windows, please follow the steps below:
At the time of this article, the current BIOS version for your computer is 1.6. You can find the updated BIOS 'software' on the Acer Support Site -Downloads & Support Documents - Aspire / Aspire 5534
The cause of your problem may also be that the BIOS battery needs replacing. It's sorta like a battery that goes into a watch or remote key fob for your car. Check the ACER site for the location and type of batter required for your system. (The Acer support site has an article on this topic: How do I maintain and store my notebook battery? Document ID: 2384)
Now, if the computer still doesn't come on after the 4 power button test, you might have an issue with the memory which is installed on the machine. Acer does not support users replacing memory, their website says to contact them directly if you suspect a memory issue.
Hope this helps and Good Luck!!!
Which windows file systems support disk quotas?
NTFS supports disk quotas. The varieties of FAT do not. UDF and ISO9660 and similar removable media file systems do not support disk quotas.
NFS and SMB network file systems will honor any disk quotas that their server enforces.
Why is DVD more suitable for backing up files?
Many people often ask why DVD's are better at storing files or data than a CD for backup. Reasons being that a DVD has a greater storage capacity therefore you will benifit more from using the DVD as storage rather than a CD.

How do you edit windows xp source code?
The source code for Windows XP is not publicly available; thus you cannot edit it.
you probably need to clean the disc of fingerprints or grease. If that does not work then try restarting your computer then putting the disc back in or go into your drives and see if theres a virus or something is wrong.

Repair windows live mail corrupt calendar and Windows live mail shuts down and will not launch.?
When you launch windows live mail, the very first item Windows live mail needs to tend to is the calendar. So there are many reasons why Windows live mail won't launch. One possible attempt to correct this is to uninstall windows live mail, and reinstall it. Microsoft also has a repair utility built into the installer if you run it again. Also check to see that DCOM services are running, and in the automatic setting. The DCOM services are located in the system administration tools, or in the Control Panel under Maintenance.
Yes, as long as the filepath is not identical.

Is Windows vista better than Windows XP for Autocad 2008?
It virtually completely depends on you. I prefer Windows XP over Vista, but generally Vista computers require more memory, RAM, higher processors, etc. The following are the requirements for AutoCAD:
== The system requirements for 32-bit AutoCAD: * Intel® Pentium® 4 processor, 2.2 GHz Recommended * Microsoft® Windows Vista™, Windows® XP Home and Professional (SP2), Windows® 2000 (SP4) * 512 MB RAM * 750 MB free disk space for installation * 1024x768 VGA with True Color * Microsoft® Internet Explorer® 6.0 (SP1 or higher) Available on CD (Worldwide) and DVD (select countries and languages) == * Windows XP Professional x64 Edition and Windows Vista 64-bit * AMD64 or Intel EM64T processor * 1GB RAM, 2GB for Windows Vista 64-bit * 750 MB free disk space for installation AutoCAD 64-bit cannot be installed on a 32-bit Windows Operating System.
== * Intel® 3.0 GHz or greater * 2 GB RAM or greater * 2 GB free hard disk available not including installation * 1280 x 1024 32-bit color video display adapter (True Color) 128 MB or greater, OpenGL®, or Direct3D® capable workstation class graphics card. * For Windows Vista, a Direct3D capable workstation class graphics card with 128 MB or greater is required. From: http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=8446045 Answer: Windows vista need high configuration of hardware requirement. auto cad 2008. good with vista.
The easiest solution is this: Open up your computer chassis and LOOK. The more advanced operating systems will usually check for updated drivers automatically, so this isn't a issue. Some video "cards" are actually video chipsets integrated into a motherboard...and you can find the motherboard specifications online if you know the model numbers (also obtained by looking)
What task cannot be performed by the windows task manager?
You cannot fly a kite from the Windows task manager. Seriously, it would be easier to tell you what you can do rather than what you cannot do. The task manager allows you to view all running processes, examine CPU, memory and resource consumption, execute new processes and terminate stalled processes.
Each process in Windows Vista operating system contains its own independent virtual address space
with both code and data, protected from other processes. Each process, in turn, contains one or more
independently executing threads. A thread running within a process can create new threads, create new
independent processes, and manage communication and synchronization between the objects.
By creating and managing processes, applications canhave multiple, concurrent tasks processing files,
performing computations, or communicating with other networked systems. It is even possible to
exploit multiple processors to speed processing.
The following sections explain the basics of process management and also introduce the basic
synchronization operations.
• Job: collection of processes that share quotas and limits
• Process: container for holding resources
• Thread: Entity scheduled by the kernel
• Fiber: Lightweight thread managed entirely in user space.
Interprocess Communication
Threads can communicate in many ways including: pipes, named pipes, mailslots, sockets, remote
procedure calls, and shared files
Semaphore
A semaphore is created using function 'CreateSemaphore' API function. As Semaphores are kernel
objects and thus have security descriptors and handles. The handle for a semaphore can be duplicated
and as a result multiple process can be synchronised on the same semaphore. Calls for up
(ReleaseSemaphore) and down (WaitForSingleObject) arepresent. A calling thread can be released
eventually using WaitForSingleObject, even if the semaphore remains at 0.
Mutexes
Mutexes are kernel objects used for synchronization and are simpler than semaphores as they do not
have counters. They are locks, with API functions for locking (WaitForSingleObject) and unlocking
(releaseMutex). Like Semaphores, mutex handles can beduplicated.
Critical Sections or Critical Regions
This is the third synchronization mechanism which is similar to mutexes. It is pertinent to note that
Critical Section are not kernel objects, they do not have handles or security descriptors and cannot be
passed between the processes. Locking and unlockingis done using EnterCriticalSection and
LeaveCriticalSection, respectively. As these API functions are performed initially in user space and only
make kernel calls when blocking is needed, they are faster than mutexes.
Events
This synchronization mechanism uses kernel objects called events, which are of two types: manual-reset
events and auto-reset events. The number of Win32 APIcalls dealing with processes, threads, and fibres
is nearly 100. Windows Vistaknows nothing about fibres and fibres are implemented in user space. As a
result, the CreateFibre call does its work entirely in user space without making 12-13 system calls.
Scheduling There is no central scheduling thread in Windows Vistaoperating system. But when a thread
cannot run any more, the thread moves to kernel mode and runs the scheduler itself to see which
thread to switch to and the concurrency control is reached through the following conditions
• Thread blocks on a semaphore, mutex, event, I/O, etc.: In this situation the thread is already running in
kernel mode to carry out the operation on the dispatcher or I/O object. It cannot possibly continue, so it
must save its own context, run the scheduler to pickits successor, and load that threat's context to start
it.
• It signals an object - In this situation, thread is running in kernel mode and after signaling some object
it can continue as signaling an object never blocks.Thread runs the scheduler to verify if the result of its
action has created a higher priority thread. If so, a thread switch occurs because Windows Vistais fully
pre-emptive.
• The running thread's quantum expires: In this case, a trap to kernel mode occurs, thread executes the
scheduler to see who runs next. The same thread may beselected again and gets a new quantum and
continue running, else a thread switch takes place.
MEMORY MANAGEMENT
Windows Vistaconsists of an advanced virtual memory management system. It provides a number of
Win32 functions for using it and part of the executives and six dedicated kernel threads for managing it.
In Windows 2000, each user process has its own virtualaddress space, which is 32 bit long (or 4 GB of
virtual address space). The lower 2 GB minus approx 256MB are reserved for process's code and data;
the upper 2 GB map onto to kernel memory in a protected way. The virtual address space is demand
paged with fixed pages size.
INPUT/OUTPUT IN WINDOWS VISTA
The goal of the Windows VistaI/O system is to provide a framework for efficiently handle various I/O
devices. These includes keyboards, mice, touch pads,joysticks, scanners, still cameras, television
cameras, bar code readers, microphones, monitors, printers, plotters, beamers, CD-records, sound
cards, clocks, networks, telephones, and camcorders.
FILE SYSTEM MANAGEMENT
Windows Vistasupports several file systems like FAT-16, FAT-32, and NTFS. Windows Vistaalso supports
read-only file systems for CD-ROMs and DVDs. It is possible to have access to multiple file system types
on the same running system.
New Technology File System (NTFS)
NTFS stands for New Technology File System. Microsoft created NTFS to compensate for the features it
felt FAT was lacking. These features include increased fault tolerance and enhanced security. Individual
File names in NTFS are limited to 255 characters; full paths are limited to 32,767 characters. Files are in
Unicode. But Win32 API does not fully support case-sensitivity for file names. NTFS consists of multiple
attributes, each of which is represented by a stream of bytes
Security
NTFS has many security options. You can grant various permissions to directories and to individual files.
These permissions protect files and directories locallyand remotely. NT operating system was designed
to meet the U.S. Department of Defense's C2 (the orange book security requirements). Windows Vista
was not designed for C2 compliance, but it inherits many security properties from NT, including the
following: (1) secure login with anti-spoofing mechanism, (2) Discretionary access controls, (3) Privileged
access controls, (4) Address space protection per process, (5) New pages must be zeroed before being
mapped in, (6) security auditing
File Compression
Another advantage to NTFS is native support for file compression. The NTFS compression offers you the
chance to compress individual files and folders of your choice.
