You are looking at aWeb page right now.You can view HTML pages in two ways:* One view is their appearance on a Web browser, just like this page -- colors, different text sizes,graphics.* The other view is called "HTML Code" -- this is the code that tells the browser what to do.

In HTML, a tag tells the browser what to do. When you write an HTML page, you enter tags for manyreasons -- to change the appearance of text, to show a graphic, or to make a link to another page.

How do I create frames? What is a frameset?

Frames allow an author to divide a browser window into multiple (rectangular) regions. Multipledocuments can be displayed in a single window, each within its own frame. Graphical browsers allow

these frames to be scrolled independently of each other, and links can update the document displayed inone frame without affecting the others.You can't just "add frames" to an existing document. Rather, you must create a frameset document thatdefines a particular combination of frames, and then display your content documents inside those frames.The frameset document should also include alternative non-framed content in a NOFRAMES element.

The HTML 4 frames model has significant design flaws that cause usability problems for web users.Frames should be used only with great care.

What is a Hypertext link?

A hypertext link is a special tag that links one page to another page or resource. If you click the link, the

browser jumps to the link's destination.

discover. Not only that, but they also allow you to quickly change how your data is summarised withalmost no effort at all. This lesson will show you how to create a simple pivot table in Excel to summarise

a set of daily sales data for a team of several sales people.

batch file

Afilethat contains a sequence, or batch, ofcommands.Batch files are useful forstoringsets of

commands that are alwaysexecutedtogether because you can simply enter thenameof the batch file

instead of entering each command individually.

InDOSsystems,batch files end with a.BATextension.For example, the following DOS batch file prints

the date and time and sets thepromptto GO>:

date

time

prompt [GO>]

Whenever youboota DOS -basedcomputer,the system automatically executes the batch file named

AUTOEXEC.BAT,if it exists.

Difference between Internal and External

Command?

Answer

In MS-DOS the two ways that commands are executed are referred to as internal command and

external command. The difference between the two terms is that an internal command is

embedded into the command.com file, while an external command requires a separate file to be

used. Internal commands can be used without a file or disk. Some common internal commands

include copy, date, delete, and exit. Some common external commands include format, backup,

find, more, recover, restore, and print.

What is an external and internal command?

Question

What is an external and internal command?

Answer

In MS-DOS there are two ways commands are executed. An Internal command, which is a commandembedded into the command.com file, and an external command, which is not embedded into

command.com and therefore requires a separate file to be used.

For example, if your computer does not have fdisk.exe and you try using the fdisk command, you wouldreceive an error "Bad command or file name." Fdisk is an external command that will only work if

fdisk.exe, or in some cases, fdisk.com, is present.

However, as long as MS-DOS is running on your computer internal commands such as thecd commandwill always be available and does not require any other files to run.

The internal commands reside in COMMAND.COM, which loads into memory when the computer system

is started; these commands do not reside on disk. The external commands are files that do reside on disk

and have an extension of .COM, .EXE, or .BAT. Both command types are executed from the MS-DOS

prompt.
