CPU to function it in a desired way.

2. What is meant by Installation and Assembling?

Installation –It is the process of loading the software package into the computer.

Assembling – It is the process of mounting different computer peripherals into one, to make the computer to function properly.

3. Define Hardware.

Hardware is the physical components of the computer.

4. What are the types of Software?

1. Application software.

2. System software.

5. Define OS.

An operating system is a set of programs, which are used to control and co-ordinate the computer system.

6. What are the basic functions of an OS?

• Process Management.

• Memory Management.

• File Management.

• Device Management.

• Security Management.

• User Interface.

7. What are the types of Operating System?

9. What are language translators?

The language translators are the programs which come under system software category. They are Compilers, Interpreters and Assembler.

10. What are a Compiler, Assembler and Interpreter?

Compiler: It is a program which is used to convert the high level language program into machine language.

Assembler: It is a program which is used to convert the assembly level language program into machine language.

Interpreter: It is a program; it takes one statement of a high level language program, translates it into machine language instruction and then immediately executes the resulting machine language instruction.

11. What is Device Driver?

In computing, a device driver or software driver is a computer program allowing higher- level computer programs to interact with a hardware device.

A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware connects.

12. What is the purpose of a Device Driver?

A device driver simplifies programming by acting as a translator between a hardware device and the applications or operating systems that use it. Programmers can write the higher-level application code independently of whatever specific hardware device it will ultimately control, because code and device can interface in a standard way, regardless of the software superstructure or of underlying hardware. Every version of a device, such as a printer, requires its own hardware-specific specialized commands.

13. What is a linker?

A linker is a program that combines object modules to form an executable program.

Many programming languages allow you to write different pieces of code, called modules, separately. This simplifies the programming task because you can break a large program into small, more manageable pieces.

Modules has to be put together. This is the job of the linker.

In addition to combining modules, a linker also replaces symbolic addresses with real addresses. Therefore, you may need to link a program even if it contains only one module.

14. What is a loader?

In computing, a loader is the part of an operating system that is responsible for one of the essential stages in the process of starting a program, loading programs, that is, starting up programs by reading the contents of executable files (executables- files containing program text) into memory, then carrying out other required preparatory tasks, after which the program code is finally allowed to run and is started when the operating system passes control to the loaded program code.

15. What is Booting?

In computing, booting (also known as "booting up") is a bootstrapping process that

starts operating systems when the user turns on a computer system. A boot sequence is the initial set of operations that the computer performs when power is switched on. The boot

loader typically loads the main operating system for the computer.

16. What is application software?

An application software is a set of programs, that allows the computer to perform a specific

data processing for the user.

31. Define protocol?

In computing, a protocol is a set of rules which is used by computers to communicate with each other across a network. A protocol is a convention or standard that controls or enables the connection, communication, and data transfer between computing endpoints. In its simplest form, a protocol can be defined as the rules governing the syntax, semantics, and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest level, a protocol defines the behavior of a hardware connection.

38. What is HTTP?

Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. Its use for retrieving inter-linked resources, called hypertext documents, led to the establishment of the World Wide Web in 1990.

There are two major versions, HTTP/1.0 that uses a separate connection for every document and HTTP/1.1 that can reuse the same connection to download, for instance, images for the just served page. Hence HTTP/1.1 may be faster as it takes time to set up the connections.

39. What is TCP/IP?

Transmission Control Protocol/Internet Protocol, the suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the Internet, making it the de facto standard for transmitting data over networks. Even network operating systems that have their own protocols, such as Netware, also support TCP/IP.

40. Define URL?

A Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. In popular usage and in many technical documents and verbal discussions it is often incorrectly used as a synonym for URI.[1] In popular language, a URI is also referred to as a Web address.

41. Define ISP?

An Internet service provider (ISP, also called Internet access provider, or IAP) is a company that offers its customer’s access to the Internet. The ISP connects to its customers using a data transmission technology appropriate for delivering Internet Protocol datagram’s, such as dial-up, DSL, cable modem, wireless or dedicated high-speed interconnects.

ISPs may provide Internet e-mail accounts to users which allow them to communicate with one another by sending and receiving electronic messages through their ISP's servers.

ISPs may provide other services such as remotely storing data files on behalf of their customers, as well as other services unique to each particular ISP.

42. Define Home page?

The homepage (often written as home page) is the URL or local file that automatically loads when a web browser starts or when the browser's "home" button is pressed. One can turn this feature off and on, as well as specify a URL for the page to be loaded. The term is also used to refer to the front page, web server directory index, or main web page of a website of a group, company, organization, or individual.

43. Define Web Browser?

A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content. Hyperlinks present in resources enable users to easily navigate their browsers to related resources.

The major web browsers are Windows Internet Explorer, Mozilla Firefox, Apple Safari, Google Chrome, and Opera.

50. What is soft loading? (JAN 2009)

A soft reboot (also known as a warm reboot) is restarting a computer under software

control, without removing power or (directly) triggering a reset line. It usually, though not always, refers to an orderly shutdown and restarting of the machine.

The Control-Alt-Delete key combination is used to allow the soft rebooting the system.

51. What are the steps involved in booting? (JAN 2009) First, the Power On Self Tests (POST) is conducted. These tests verify that the system is

operating correctly and will display an error message and/or output a series of beeps known as beep codes depending on the BIOS manufacturer.

Second, is initialization in which the BIOS look for the video card built in BIOS program and runs it. The BIOS then looks for other devices' ROMs to see if any of them have BIOSes and they are executed as well.

Third, is to initiate the boot process. The BIOS looks for boot information that is contained in file called the master boot record (MBR) at the first sector on the disk. If it is

searching a floppy disk, it looks at the same address on the floppy disk for a volume boot sector. Once an acceptable boot record is found the operating system is loaded which takes over control of the computer.
