What is better mac book air or mac book pro?
The Pro is better - i have heard the air can break really easily because it is so light and flimsy.
I disagree. The air is faster and easier to carry around. The pro might freeze now and then, but the air wont. I have it and it never broke on me once or froze on me.
It depends, if you're looking for more memory and amazing performance, get the mac book pro. If you're looking for something to travel with or a simple, basic computer for surfing the web or email etc., get the mac book air.
What is the difference between a menu bar and a standard bar in Windows XP?

Another is in classic form. Standard is an option on Tool bar.
What is the function of the OS scheduler?
The scheduler's job is deciding when each process gets a shot at CPU time and for how long. While their approaches are different, they all follow roughly the same strategy:
First, assume that the CPU can run only one process at a time. CPUs with multiple cores are treated as multiple CPUs that can only run a single process or thread. Therefore the scheduler will determine that X amount of processes can be in a "running" state, where X is the number of cores or CPUs.
Second, assume that any process waiting for I/O is not going to accomplish anything while on the CPU, so do not schedule the process until its associated I/O operation has been COMPLETED by the hardware in question.
Third, assume that not all processes are equal in importance. Some processes really do not need much CPU time, so do they really need to preempt a process that does need plenty of CPU?
Fourth (In preemptive scheduling.), the kernel and not the processes, have full control over when context switching occurs, including when a process's time slice expires. Further, a process can and should be able to preempt itself when asking for I/O so that the kernel can arrange the operation with the drivers.
Finally, assume that all processes are flawed and just waiting to try and take each other's stuff. The scheduler itself will not implement memory protection, but it does need to know how to interpret whatever memory management is in place for context switching purposes.
A diacritical mark (˜) placed over the letter n in Spanish to indicate the palatal nasal sound (ny), as in cañon, or over a vowel in Portuguese to indicate nasalization, as in lã, pão.
A symbol used in Windows, starting with Windows 95, that maintains a short version of a long file or directory name for compatibility with Windows 3.1 and DOS. For example, the short version of a file named "Letter to Joe" would be LETTER~1. Then "Letter to Pat" becomes LETTER~2. In the Unix world, all the popular Unix shells (except for the Bourne shell) support a home directory name substitution using the tilde. Also called a "squiggle" or "twiddle," the symbol is used as a prefix to a user login name to specify that user's home directory. For example, if your user name were "jackson," you would use ~jackson to refer to your home directory. The tilde symbol is a Spanish accent that turns the letter "n" into a "nyeh" sound such as in the word mañana, which is pronounced "mah-nyah-nah" and means "morning" or "tomorrow." The tilde is also used as a mathematical symbol that means the difference between two values or an equivalency between two values. The tilde can also be used as an abbreviation to indicate approximation. ~50 = "approximately 50." It is technically supposed to be two tildes, one over the other, but it has become common to simply use the one symbol. Also, the tilde is used in Symbolic Logic to indicate a "not" value. ~A = "not A." A --> ~B = "If A, then not B"

Casual I would think. Anything more than casually using a computer is a pain on Windows 8 (Or any other tablet software for that matter) and that would always restrict you.
I would also have to look into how well those detachable keyboards are. If they are a pain to type on that could make a difference as well.

What does a window represents in GUI?
Window represents in a GUI:
When we turn on our computer, Windows is loaded automatically into the computer's memory (RAM) from the hard disk where it resides. This process of loading the operating system is called booting the system. Windows is a graphical user interface(GUI) and is easy to learn in contrast to the DOS, which is command line Interface. An interface determines how you interact with your computer to do things like entering data or running programs like changing fonts, numbering lines, breaking the text into columns or spell checking.

Why would your computer not boot up?
if you're using Windows, just insert a recovery disc and a lot of time it will fix it, if that doesn't do it , clean install, sometimes the hdd could have a problem not related to windows at all but sometimes they will just not read right and need to be reformatted.
When Windows fails to boot it is normally caused by a user installing a program or device and it has caused a conflict with one or more other programs. This will no doubt give you plenty of heartache if you're not certain which program caused Windows to not boot up.
If you recently installed a program or application and know where it was installed,you may be in much better shape as for as correcting the error. Here are common ways to correct the problem of your computer not completely booting up or not booting up at all.
If your computer will not boot-up at all,hopefully you have made a good emergency boot disk. You can always make a windows startup disk by creating one from another computer running Windows 98 or Me. Perform the following if your computer won't Boot-Up At All.
FIRST: Put your boot floppy disk in the floppy drive and turn on the PC.On some computers, you may have to access the bios and select the Boot priority to your A: drive. Save any changes and select "Start Computer without CDROM support" and press Enter. Once you are at the A prompt,type dir c: and press enter.
If your programs and other files are present,try restoring your system Registry by following the steps below.This may repair Windows,the Config. Sys and autoexec.bat files to where the PC may boot up normally. When the files are present, it's a good indication of a good hard drive.
SECOND: To correct the problem of your computer not booting up,type in "fdisk /mbr" and press Enter to restore your master boot record.Type "Scandisk C:" to check the hard drive for errors that have occurred. You can also type "Sys C:" to hopefully restore files needed to boot up your computer.
THIRD: If the above procedures fail to repair your computer,you can repeat the first part of step one above and select "Start Computer With CDROM Support" re-install Windows.
Making A Windows XP Bootable Floppy Windows XP users should create a boot disk now by placing a formatted blank diskette in the A: drive, open Windows Explorer to the C:,select Tools,Folder Options ,show Hidden files and and folders,then View Tab. Now you uncheck "Hide Protected Operating System Files (recommended). You will see a warning and click Yes and click OK. Copy the files ntldr,ntdetect.com and boot.ini onto the disk. Remove the disk and label it the Windows XP Boot Disk.
After making your boot disk, recheck "Hide protected operating system files and folders (recommended)" in the Folder Options dialog box. To use the disk when Windows XP won't boot,place the disk in the drive,and unto re-booting,the computer, Windows simply bypass the basic boot files on the hard drive and continue to boot up.
If The PC Won't Boot Past Windows
FIRST: If your Operating System is Windows Millennium,turn on the computer and immediately press and hold down the CTRL key. Once the startup options appear,release the CTRL key. Select Safe Mode and press Enter. You are now in Windows limited version. If you know what caused your computer not to boot,you can now either change or delete that program.
SECOND: Repair your Registry by selecting Start,Run and typing "scanregw /fix" and press enter. This will fix any damage done to the Registry. You can also restore your registry which replaces your current registry with an earlier copy that was backed up by your computer. Click on Start,Run and type "scanregw /restore and press Enter.
To repair your Windows 98 Registry,hold down the CTRL key as you start the PC and select "Command Prompt Only". Type "scanreg /fix" and press Enter and "scanreg/restore" to restore a previously saved copy of the Registry.
If you have Windows XP,press F8 after rebooting the PC should Windows freeze while booting up. You can select "Last Known Good Configuration" after rebooting to allow the computer to boot the last backed up files.And you can choose "Safe Mode" to remove any files you know caused the operating system to hang up.
Be prepared when your operating fails to boot. It would be a great idea to go over this article a few times and print it. Make yourself s notebook and place this and all related articles there.
If your computer fails to boot or begins to become unstable,you can refer to these articles to make corrections that are needed. Learn these steps from your television set with the PC Super Pack.
Be sure to note any changes you make to your Registry and if you're not sure,its best to find a friend that's PC savvy first. Above all,be certain you backup your registry before making any changes and know how to restore as well.
First things First: PC is not booting up, not even BIOS is shown:
Check the Power Supply.
See if the SMPS Fan is working.
Open the Case and see if the Motherboard LED is Glowing.
Remove all the add-on cards and have only a single RAM (if you have more than 1).
Reset the BIOS (check motherboard manual).
Try to Boot.
Watch for Motherboard beeps.
Have a POST guide and try to figure out the post code.
If BIOS is OK and problem with Booting of Windows/Mac/Linux see above.
How do you use the memo data type in Microsoft access?
The Memo data type is used like you would use the text data type in Mysql or Sql Server. It is a data type for large texts. In MS Access the Text data type can contain a maximum of 255 characters, for larger texts you use the Memo type.

What are the similarities between Windows Mac and Linux operating systems?
Windows, Mac OS and Linux are all operating systems. All three can be used in computer desktops, laptops, netbooks, notebooks, smartphones, tablets, etc. You can use any of the three to surf the web, check your email, video chat, as word processors, video editors, for music listening, recording and production, graphics design, and the list goes on and on. However, the software that you use to accomplish the tasks I mentioned might be different depending on which operating system you're using. For example, to go on the internet you a need a web browser: Windows PCs come standard with Internet Explorer, Mac PCs come with Safari, and Linux usually comes with Mozilla Firefox, Google Chrome, or an offshoot of the two (Iceweasel, Chromium, etc).
What is a small window that pops up in an application that requires a response from the user?

The best tool to verify that hardware components installed in Windows are working properly is the Device Manager. It provides a comprehensive overview of all hardware devices and their status, indicating whether they are functioning correctly or if there are any issues, such as driver problems or conflicts. Users can also access properties for each device to troubleshoot issues or update drivers as needed. Additionally, Windows Performance Monitor can be used for more detailed performance analysis of hardware components.
What two things do you need to do in order to be able to log onto a LAN?
