Q1. Define computer with block diagram? explain the components of computer in details?
Answer:

Computer is an electronic processing machine which get the input , process on it very fast speed and then give the out put after processing. Computer also stores our information and we cab access this information any time when we need. A computer capable of performing computation and making logical decision at speeds thousands of even million of time faster than human being.

1. Input Unit
2. Output unit
3. Central Processing Unit (CPU)
4. Memory Unit 

Input unit: -
The basic unit, which provides communication between the user and the computer, is the input unit. This unit describes a device, used to transfer information into a computing system. It performs following three functions.
- It accepts data from user.
- Converts that data into electrical signals, which can be later, used in arithmetical calculations.
- Coded data is then moved to the system for processing.
The data can be fed into a computer by using different types of input devices. The commonly used input devices are Keyboard, MOUSE etc.
Central Processing Unit (CPU)
CPU is short form central processing unit. The central processing unit is responsible for performing all of the mathematical and logical calculations that are required for a computer to function properly means that work of CPU is Data Processing. The function of CPU is consist on four steps to perform processing function. The first step in this cycle is to fetch a instruction from a software program's memory. Once the CPU fetches the instruction, its second step is to decode the instruction. By decoding the instruction, the CPU is able to organize the information from the instruction in a manner that allows the CPU to complete the next step, which is executing.

Memory Unit:
Memory unit responsible for storing the information permanently and temporary during the processing. Computer memory is mainly divided in to two types.
i - Primary Memory
ii - Secondary Memory
Primary Memory:
Primary memory stores the information in form of binary coded data. Primary memory holds the input data (before processing), result for output purpose (after processing) and also provides the permanents storage as requested. It is usually refer to main memory and also known as Internal Memory.
Main memory consists on RAM, ROM, and Cache Memory.
Secondary Memory:
The Secondary Memory is also known as auxiliary storage or external storage which store the permanently.
Out Put Unit:
The out put unit give the output of our input after processing. This is final step , which presents the results of the machine operations in printed or other visual form. It is a device that receives results from a CPU. It can be a communicating link between a computer and people. It. is used to transfer information out of a computing system.

Q2. Discuses Super Computer and Mini computer with example?

Answer:
Super Computer:
Supercomputer have great speed and memory. A super computer process the jobs faster than other computer. The Super computer is thousands of times faster than ordinary personal computers. Supercomputer are used for scientific and engineering applications. they can handle very large databases and perform grater computation.
For example, weather forecasting requires a supercomputer and super computer is also used in nuclear energy research and petroleum exploration.
Mini Computer
Mini computer are smaller then main frame computer but larger then micro computer. Mini computer are compact computer and use small memory and these computer are less expensive. These type of computer designed for the scientific research and data collection.
Mini computer are normally fills small rooms because it also includes many types of peripherals equipments attach to it. mini computer also uses the Disk for storage and also use tape disk for backup. Mini computer system are typically interactive system and are used to enter data directly in to the computer via keyboard. Mini computers are also used for networking purpose.
Some of the most popular Mini computer are :
MAI Basic4
DEC PDP and VAX Series
Prime Computer Prime 50
Data General Nova

Q3. Explain application of computer in different fields of life?

Today's computer is used in all the filed of life and its play very important role in development. With the help of computer all the difficult task become easy and time saving with the help of computer. Following are the some very common use's of computer.
Word Processing
Word Processing software is an specially gift for those people who work in office. Word Processing application automatically corrects spelling and grammar and mistakes. If the content of a document repeats you don?t have to type it each time just copy the contents and paste. You can printout documents and make several copies in very short time. It is easier to read a word-processed document than a handwritten one. You can add images to your document.
Internet and sharing information: You can share your document and other work with different people on the network. On the internet you can browse through much more information than you could do in a library. That is because computers can store enormous amounts of information. You also have very fast and convenient access to information. Through E-Mail you can communicate with a person sitting thousands of miles away in seconds. There is chat software that enables one to chat with another person on a real-time basis. Video conferencing tools are becoming readily available to the common man.
Digital video or audio composition
Audio or video composition and editing have been made much easier by the use of computers. Graphics engineers can use computers to generate short or full-length films or even to create three-dimensional models.
Computers in Medicine: -
You can diagnose diseases. You can learn the cures. Software is used in magnetic resonance imaging to examine the internal organs of the human body. Software is used for performing surgery. Computers are used to store patient data.

When one or more than one computer are connected with each other for the purpose of sharing information and share resources (such as printers and CDs), exchange files, or allow electronic communications is called Network. The entire computer in the network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.
The two basic types of networks include:
Local Area Network (LAN)
Wide Area Network (WAN)
Metropolitan Area Networks (MAN)
Local Area Network: -
The network in a single building or some group of building is called local aria network. Generally we sat that the network which is established relatively small area is called local area network. For example the network in a lab, in a schools and in a building. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. You can link these computer through a cables are used to connect the network interface cards in each computer. You can also use wireless LAN card.
Wide Area Network
Wide Area Networks (WANs), extent on larger geographic areas. We say collection of more than one network on relatively large aria is called wide area network. A Computer connected to a wide-area network through public networks, such as the telephone system. They can also be connected through the satellites. One of the most popular examples of wide area network is Internet.
Metropolitan Area Networks (MAN)
A Network which spared on grater aria from local aria but less form wide aria network. We also say that the interconnection of networks in a city into a single larger network is called metropolitan aria network.

Q6. Convert The given number system to its required number system?

(65)8 = (?)10
(25)10 = (?)2
(1100)2 =(?)10
(BA)16=(?)10

Q7. Define the following:
Data with its types
Application software
Answer:

Data:
Data is a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things. Any thing in the raw form means that not meaningful from is called data. Computer data may be processed by the computer and stored in files and folders on the computer. The data that stored in computer is always in binary form.
Types of data:
1. Alphabetic data
2. Numeric data
For example The score of the student or he number of visitors to a website by country is an example of data
Alphabetic data: Capital letter from A-Z and small letterform a-z
Numeric data: Decimal number from 0-9 and decimal point notation
Alphanumeric data: Alphabetic, numeric and special character/symbol.

Application Software:
Application software some time also called application package are developed for specific purpose to get the required output. These type of software developed by experts in high/low level languages for end user how use these software. The user can easily learn to operate these software after getting some initial training. There are many these type of software are available in the market which are used for different purpose. for example word processor for writing and printing the document (e.g MS word Lotus 123), DBMS for creating and managing Database (e.g MS Access , SQL , fox prow), Graphics software (e.g Adobe , Image composer), Multimedia software for playing videos (e.g Media player) and games (e.g Prince, Dave).

Q8. Discuss the following:
Computer Language
Use of Internet

Computer Languages:
Computer is an electronic machine when we give some instruction to computer (when we write any program ) then we must have some language form which we communicate with computer these language are called computer language. For this purpose different languages are developed for performing different- types of work. Languages are divided into two categories.
A. Low Level Language
B. High Level Language
A) Low Level Language: -
The Low-level languages are primary language of computer machine codes. Computer cannot understand instructions given in English. It can only understand and execute instructions given in the form of machine language i.e the language of 0 and 1. There are two types of low-level language. Machine Language: It is the lowest and most elementary level of programming language and was the first type of programming language to be developed Machine language is basically the only language which computer can understand Machine language is represented inside the computer by a string of binary digits 0, 1. the symbol 0 stands for the absence of an electric- pulse and 1 for the presence of an electric pulse. Since a computer is capable of recognizing electric signals, therefore it understands machine language.
Assembly Languages: It was developed to overcome some of the many problems of machine language. This is also a low level language but it is very important. This language is also very difficult and needs a lot of practice to master it. This language mainly helps in compiler orientation. The instructions of the Assembly language will also be converted to machine codes by language translator to be executed by the computer.
B) High Level Language:
These type of language easy to understand for human. The High-level language is just like English language and the purpose of developing high-level languages is to enable people to write programs easily. When we write a program in any high level language then first its transfer in to machine code for this purpose a special software are used which translate these instruction in ot machine code called translator are used. High level languages are basically symbolic: languages that use English words and mathematical symbols rather than codes. For example Visual BAsic , C language , C++ ect.
Use of Internet:
Internet is a subnet of Global network. with the help of internet the network of all over the world are connected with each other and share the information over the world. now a days the internet is one of the most important part of our daily life. There are many numbers of things that can be done using the internet.
Communication:
With the help of internet we can communicate with any one in all over the world very easy and in few minute. we can send E-mail to any one , we can chat with any one and get reply at same movement, we can also do video chat in which we can see each other and talk to each other. we can also perform video conference.
Education and research The internet is vary helpful in the education and research. There are a number of books, reference books, online help study centers, expert?s views and other study oriented material on the internet that can make the learning process very easier. we can apply on line admission for university and college. Now with the help of internet we can give online exam and submit assignments. when we do soemm type of research then we need to hundreds of books as well as the references and that was one of the most difficult jobs, but now with the help of internet everything is available just a click away.
Financial Transaction
with the use of internet in the financial transaction the work has become a lot easier. we can manage our bank account perform bank transaction at home with the help of online banking.
News and Update:
with the help of internet we get latest news and update at real time. we can watch the things happened in all over the world at home.
Shopping:
with the help of internet every things are reached to the home of people. every one who have internet can by and sale his product at home. on line shop is one of the example.
Entertainment: There are many different ways that you can choose to spend your time online. Through the internet we can play on line games, we can listen to music, you can watch and download video and television from different channels.
