Windows Explorer

Q9. What is Windows Explorer? Give some of its functions?

Ans. Another way of seeing what’s on your computer is to use Windows Explorer. Opening Windows Explorer gives you a view of your computer’s contents as a hierarchy, or “tree”. You can easily see the contents of each drive and folder on your computer, as well as of any network drives you are connected to.

 

My Computer, Network Neighborhood, Recycle bin, Start Menu, Task Bar and Help

Q5. What is the significance of the following:

(a) My Computer

(b) Network Neighborhood

(c) Recycle bin

(d) Start Menu

(e) Task Bar

(f)  Help

Ans. (a). My Computer

In Windows XP, the things you have on your computer – your programs, documents, and data files, for example – are all accessible from one place called My Computer. My computer is helpful if you prefer viewing the contents of a single folder or drive. When you double-click My Computer on your desktop, available drives appear in a new window. When you double-click a drive icon, a window display the folders contained on that drive. You can then double-click a folder to see the files it contains.

 

Ans.(b). Network Neighborhood

Windows 95 folder that lists computers, printers and other resources connected to your local-area network (LAN). By default, a Network Neighborhood icon appears on your desktop, and the folder is also accessible from within the Windows 95 Explorer. The Network Neighborhood is designed to replace the drive mapping older system, which associates a letter with each shared disk drive. Many programs, however, still require drive mapping.

The Network Neighborhood serves no purpose if your computer is not connected to a LAN, except that it is required to link two computers using Windows 95’s Direct Cable Connection (DCC)feature.

 

Ans.(c). Recycle Bin

The files that you delete are put in the Recycle Bin, a holding place for files you no longer need. They are actually not removed from your hard disk until you empty the Recycle Bin.

This means you can retrieve files you deleted in error, if you have not already removed them from the Recycle Bin. However, this also means that if you eant to free up disk space, you must empty the Recycle Bin periodically.

 

Ans.(d). Start Menu

Using the Start button, you can accomplish almost any task. You can start programs, open documents, customize your system, get help, serch for items on your computer, and more. Some commands on the Start Menu have right-facing arrow which means additional choices are avialable on a secondary menu. if you place your pointer over an item with an arrow, another menu appears.

 

Ans.(e). Taskbar

This is a bar that is usually found at the bottom of your screen. Taskbar hosts start button, clock and the buttons corresponding to all open windows.

Buttons on the taskbar show you which windows are open, even if some windows are minimized or hidden beneath another window. You can easily switch to a different window by clicking its taskbar button.

 

Ans.(f). Help

Opens Windows Help, where you can browse and search Help topics about using Windows and your computer.

Filename And Pathname

Q2. How is a filename different from pathname? Support your answer with examples.

Ans. Filename

Each file storedd on the system is given a name. The file name has two parts:

(i) primary file name and

(ii) secondary file name (also called extension)

 

A primary file name consists of one to eight (1-8) characters in length. File extension consists of a period followed by zero to three (0-3) characters. Extensions are optional, but it is better to use them as they are useful for describing the contents of a file. For instance, all document files can be given an extension .doc. The primary file name and extensions can have any characters other than following:

Extension .exe specifies that it is an executable file, .bas specifies it is BASIC program file, .PAS specifies that it is Pascal file, and so on. Therefore, extensions can be used for better understanding of filename.

In the same manner, as files are given names, disk are given internal names called volume label. It is an 11 character name given to a disk (be it FDD or HDD) for better description of its contents. External paper labels can also be put outside a floppy disk, on which descriptive names can be written to help one identify its contents.

 

Pathname

Path is a sequence of directory names which give you the hierarchy to access a particular directory or file name.

The format of path is

Drive-letter:\directory [\directory…]

where first \ (backslash) refers to root directory and other (‘\’s) separate a directory name from the previous one.

 

The full name of a file or a directory is also called pathname.

For example:

A:\PROJECT\PROJ2\ONE.CPP
