interview questions

What is BIOS (Basic Input and Output Software)?

Ans. BIOS stands for Basic Input and Output Software. The BIOS is software that controls the most fundamental operations of a computer and a BIOS is necessary in order to start a computer. Without a BIOS, a computer would not know how to communicate with its hard disk and other devices. The BIOS is stored on a ROM (Read-Only Memory) computer chip inside the computer. Many computers in the past few years use "Flash EPROM" chips, which means the BIOS chip can be reprogrammed with an updated BIOS. A BIOS may need to be updated to fix bugs, such as the year 2000 bug, or an update may be necessary in order to support new hardware protocols.

 What is Cascade?

What is Command?

Ans. An option form an application's menu, or a command typed in by the user, such as at a DOS prompt or at the Run dialog box in Windows.

6. What is Driver software?

Ans. Driver software is software that works as a translator between another program and some piece of hardware. In the software industry, there are generally standard ways to do things. There are many different types of hardware, however, and each piece of hardware may have its own protocol (or "language"). The driver software receives standard signals from another program, then translates these into commands for a particular piece of hardware. This way a program can be written in a standard way, and it will work with many different devices.

6. What is Modem?

Ans. A device, usually connected to a serial port of a computer, that transmits data over regular phone lines. Modem stands modulator\demodulator; it converts a digital stream of data into sound for transmission (modulator) and converts incoming sound signals into data (demodulator).

. What is File?

Ans. A file is a long sequence of bytes which represent data. Each file has a name and an extension which are separated by a dot (a period). The name, of course, identifies the file. The extension tells the computer what type of data is contained within the file. For example, a file called "Letter to George.DOC" is a Microsoft Word DOCUMENT. The file you are reading now is called "glossary.html". HTML stands for HyperText Markup Language, and it is the file type for web pages.

 What is Focus?

Ans. When you use a dialog box with many items to fill out, only one of the items can be accepting input from the keyboard at a time. The active item is said to be the item with the focus. You can press the TAB key to move the focus to the next item; press SHIFT+TAB to move the focus to the previous item. The item with the focus will usually have a dashed border around it, or it will have a blinking text cursor in it.

 What is Folder?

Ans. A folder can be thought of as a location on your hard disk or floppy disk. Folders used to be called directories/subdirectories. A folder contains files and can contain nested folders (subfolders). Folders and subfolders are used to organize your hard disk. For example, you probably already have a folder named "My Documents" on your hard disk; you could place a subfolder named "Work" under "My Documents", and place all your work documents within this subfolder. This way, you can keep your work documents separate from your personal documents.
