Q: NO. 1 DEFINE THE TERM COMPUTER. ALSO DESCRIBE BASIC FIVE OPERATION PERFORM BY THE COMPUTER.
ANSWER:- Definition: “computers are electronic devices that accept data (input), process that data, produces output, and then store (storage) the results.” First computer (ENIAC)” The first computer was called the ENIAC, which was built during World War II (1943-1946). These early computers used vacuum tubes and were very large and only found in businesses, Universities, or governments. Later, computers began utilizing transistors as well as smaller and cheaper parts that allowed the common person to own their own computer. This history of computers and related topics can be found on our history page. A computer system is an interconnected system of components that transmit electronic information between them to accomplish a task given to the computer. Computer systems require several critic& components to function, all of equal importance.
Hardware component of computer: The hardware components of the computer are the parts you can see and touch.
Software component of computer: The software components consist of electronic data and programs that give the hardware directions for functioning properly. Computers help make jobs that used to be complicated much simpler. For example, a user can write letters in a word processor and edit any portion of the letter anytime, spell check the letter, and move text from another document into the letter, etc. This is just one of the millions of different things a computer is capable of doing. Basic operations performed by computer system:
1 – Input unit: Input unit links the external environment with the computer system. Data and instruction must be entered to the computer before performing any competition. Data or instructions can be entered through input devices, eg. Key board, or any other input devices. Input unit transferred this data into binary coded.
Functions of input unit:
i- It accepts data or instructions from external world.
ii- It converts these instructions and data in computer acceptable form.
iii- It supplies the converted instruction & data to the computer for further processing.
(2) Storage unit before actual processing start, data & instructions entered to the computer must be stored inside the computer. Similarly, results produced by the computer are required to be stored before being passed to the output unit. The intermediate! Result produced by the computer must also be stored for further processing.
Function of storage unit:
i- It stores all the data to be process.
ii- It stores intermeciial results.
iii- It stores final result are realize an output device.
(3) Processing (ALU) unit: ALU is the place where actual execution of the instructions takes places during the processing operations. All calculations & comparisons are made in the ALU. The data and instructions stored in the primary storage are transferred as where required. Intermediate results are also transferred back to the ALU for final processing. After completion of processing the final results are send to storage units from ALU. Number of arithmetic & logical operation that a computer can perform is determined by the design to perform the four basic arithmetic operations. (4) Output unit It is just the viewers of that any input unit it provides information reasons of computation to the output of the world. Output unit links the computer with the external world. A computer prepares results in binary code. Output unit converts these results into human acceptable forms.

Functions of output unit It accepts the result produced by the computer. It converts these coded results to human acceptable form. It supplies the converted to the outside world.
(5) Control unit: ALU does not know what should be done with the data likewise, output unit does not know when the result should be displayed. By selecting, interning and seeing to the execution of the program the CU is able to maintain order and direct the operations of the entire system CU doesn’t perform any actual processing on data yet it is known as a central nervous system for the comforts of the commenters. It manages co-ordinates the entire system.
Q NO.2 (A) DISCUSS THE PURPOSES OF SPEECH RECOGNITION.” PURPOSES OF SPEECH RECOGNITION.”
(B): WHAT IS DIFFERENCE BETWEEN MEMORY AND HARD DISK? EXPLAIN IN DETAIL
Its purpose is listen to and understand voice commands to perform everyday tasks. The future of personal computing is the Apple Macintosh of today. Armed with speech recognition software, the Mac can listen to and understand voice commands to perform everyday tasks. Recognition of voice the sound of a spoken word creates a specific pattern of sound waves on an electronic sensor device. Computer programmers are able to take those sound wave patterns and match them with their corresponding spoken words. For example, the spoken word “cat” produces a squiggly pattern on a sound-scope that the programmer can match to a database of words on file. When someone says “cat” into a computer microphone, the program matches the sound pattern to the word on file and prints the word “cat” on the computer screen. This is a great over simplification of the process, but it explains how computers can “understand” what you say.
All modern Voice Recognition software titles “teach” your computer how to recognize your voice patterns. A tutoring stage is built into the initial installation process so that the computer can learn your manner of saying the word “cat.” We all have different accents and manners of speech; this painstaking training time helps the computer software translate your speech into correctly spelled and interpreted words on the screen.

Therefore, when you first inch across. The most common sizes are the 3.5-inch desktop drive and the 2.5-inch laptop drive. Measuring of Space on hard drives is measured in bytes. Modern drives are measured in gigabytes or terabytes, while older drives were measured in megabytes. A megabyte is 1,024 bytes, a gigabyte 1,024 megabytes (1,048,576 bytes) and a terabyte is 1,024 gigabytes (1,073,741,824 bytes).. Speed Faster drives mean faster processing. A drive running at 5,200 RPM is standard. If you pay a little more, you can get 7,200 RPM. If you have a server and-‘need real speed, you can pay more and get 10,000 to 15,000 RPM. Answer
(b): DIFFERENCE BETWEEN MEMORY AND HARD DISK
Memory and disk space are two of the most widely-confused terms in the computing world. To understand how your computer works, you must first know the difference between memory and disk space.
The hard disk, sometimes called the “hard drive” (which is actually the mechanism that holds the hard disk), is a spindle of magnetic discs that can hold several gigabytes of data. Therefore, disk space refers to how much space you have available on your hard disk for storing files. When you save a document or install a new program, it gets stored on your hard disk. The more files you download, install, or save on your hard disk, the fuller it become.
Memory, on the other hand, is not the same as disk space! Memory refers to the random access memory (RAM) inside your computer. RAM consists of small chips also known as memory modules. Your computer uses memory (RAM) to store actively running programs on the computer, including the operating system. For example, the operating system’s interface and other processes get loaded into memory when the computer boots up. When you open a program like Microsoft Word, it gets loaded into the computer’s memory as well. When you quit the program, the memory is freed up for use by other programs.

RAM can be accessed hundreds of times faster than a hard drive, which is why active programs are loaded into RAM. Only small amounts of data from hard disk does need to be loaded into the system memory at one time, computers typically have much more hard disk space than memory. For example, a 2012 computer may come with a 2 TB hard drive, and only 16 GB of RAM. If your computer informs you that you don’t have enough disk space to install a program, you need delete files from your hard disk that you don’t need or buy an additional hard drive. If your computer says there is not enough memory to run a certain program, you will need to upgrade your memory by buying more RAM. Knowing the difference between these two computer components can save you both time and money.
Q:- NO 3 WRITE DOWN THE ADVANTAGES AND DISADVANTAGES OF “INFORMATION AND COMMUNICATION TECHNOLOGY?
Advantages and disadvantages of “Information and Communication Technology”
Information Communication Technology (ICT) “Information Communication Technology (ICT) is a term that describes types of technology that are used specifically for communications.” It is like Information Technology, but ICT focuses more on technologies that deal with communication, like cell phones, the Internet and wireless networks, among other things. ,
AIOU SOLVED ASSIGNMENT 1 CODE 1431 SPRING 2017 FOR OPEN UNIVERSITY STUDENTS.
Because of the convergence of the two technologies in the sense that we increasingly use digital data to communicate, a new term has been coined: information and communication technology (ITC). Today we use computers to call, each other and telephones to process data and send emails.

USAGE OF ICT:-
The field of Information Communication Technology has taken off in the last decade. Developed countries have a higher use of ICT, but developing countries have made significant increases in use over the last five years. At the end of 2008, the world had more than 4 billion mobile phone users, and close to one- fourth of the world’s population had access to the Internet.
UTILITARIAN OBJECTIVES :-
One of the main aims of ICT is to help students to become competent and confident users who can use the basic knowledge and skills acquired to assist them in their daily lives. It is also supposed to prepare students for the world of tomorrow. It aims to help learners to have an open and flexible mind. This will help them to adjust to the inevitable future changes.

SOCIAL AIMS OF ICT
It aims to equip learners with the appropriate social skills required to cooperate with fellow ICT learners for a more productive learning experience. It empowers students who are unable to use this technology outside the school premises by ensuring sufficient access to those students. Through this, it will also ensure equity among all learners, as they will all have the same opportunities to use the ICT facilities in school.
Another social objective of ICT is to facilitate good communication between the students, thus promoting better social understanding. ICT aims to assist students to appreciate the beauty and diversity of culture. It also aims to help students become well-cultured citizens of the modern world.
AIOU SOLVED ASSIGNMENT 1 CODE 1431 SPRING 2017 B.A.
It achieves this as it facilitates the discovery and appreciation of various cultural heritages of different countries around the world. Personal Objectives ICT aims to assist students to grow personally by facilitating different methods of learning. Distance-learning programs are now provided by most colleges and universities.
Many people are using these programs to get degrees that they would not have been able to receive without ICT. It also aims to allow the public to easily access the necessary information over the Internet. Regulations Americans enjoys relative freedom in the use of ICT, but other governments are struggling to regulate its use.
Most recently, governments in the United Arab Emirates and Saudi Arabia decided to block features on Blackberry smart phones, which allow citizens to access the Internet without regulation. Starting Oct. 11, 2010, users will not be able to access email or the Internet through their BlackBerrys.
Information technology refers to devices (hardware) and algorithms or programs (software) used to store, retrieve and process data. In simple terms, it refers to all computer applications and devices. Communication Technology In the modern sense of the term, communication technology includes electronic systems used for communication between individuals or groups not physically present at the same location.
It is about ways people can talk or write to each other and exchange messages, pictures or sounds. Information and Communication Technology (ICT) has a major impact on business operations. Companies are able to utilize ICT to manage business operations from accounting to advertisement. With the rapid development of ICT, it is now possible to conduct more business transactions at a minimal cost compared to the previous era where ICT development was minimal.
Business operators and the ICT department are now able to become innovative and discover new ways to make Information and Communication technology work for them. Information and communications technology refers to a vast network of computer terminals, fiber optic cables and server equipment that collect and present data. Stock market investors are familiar with the stock ticker, which streams stock price quotes between exchange trading floors and numerous data points across the globe.
