| Using rules |
Computer is a very useful device. The computer stores all types of instructions given by the user for calculation such as numbers, numbers, text, graphics, pictures, etc. All these data and instructions are different, but the computer stores all these data and instructions in binary language. Binary is the language of a machine whose base is just two numbers - 0 and 1. All the instructions given by the user are converted to 0 and 1 in binary language. This process is called data representation . There are two methods for data representation -
1. Analog Operations
2. Digital Operations
Analog actions (Analog Operations) -
Analog verbs are based on a continuously variable signal. Numbers are not used in these. Analog functions are used in many fields of science and engineering as physical quantities are used more in these areas such as speedometer, odometer, voltmeter, thermometer etc.
Digital operation
Modern computers are made by digital electronic circuits. The main part of this circuit is the transistor which operates in two stages 0 and 1. These two stages that express data in a computer are collectively called binary number systems.
A system is created to store binary data, the smallest unit of which is bit.
4 bits = 1 nibble
8 bits = 1 byte
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
Information Technology
Introduction:
The development of computers has already taken place many decades ago, but in the modern era, the computer's capacity, speed, size and many other characteristics are amazing changes. In all this information, the invention of information technology has made many impossible things possible. We can reserve a railway-airplane ticket for chatting with any of our friends and relatives located at home. Along with the development of computers, information technology is also on the path of development. Information technology is mainly used in the form of data communication, at businesses, homes, banks, etc. In other words, the new branch of knowledge is called information technology.
Fundamental Ingredient of IT
Communication process, computer network, e-mail etc. are fundamental components of information technology. His brief description is as follows-
Communication process
The exchange of data and information between two different or similar devices is called data communication and this whole process is called communication. Communication is carried out by the following means-
1. Message
2. Recipient
3. Sender
4. Medium
5. Protocol
Computer Network: A computer network is
the interconnection of two or more computers for the exchange and sharing of information or other resources. Under the computer network, resources and information reach equally from one computer to another. Computer networks are set up between a company or buildings, a room, and the city.
Types of Network
There are different types of networks but mainly there are three types of networks-
1. Local Area Network- LAN (Local Area
Network ) A network which is limited to only one building, office or one room is called a local area network. Many computers are connected under this network. But their geographical area is one or two km. Does not exceed Examples of LANs are Ring, Star or Completely Connected Network etc.
2. Metropolitan Area Network- MAN (Metropolitan Area Network- MAN)
A network created by joining one or more local area networks together is called a metropolitan area network. This network is a large-scale network, made up of several corporates. Man speed is extremely fast, but slower than LAN.
3. Wide Area Network- WAN The
networks that are connected at the regional, national, international and regional levels are called wide area networks. Computer terminals are connected by satellite to the van. For example, it is possible to make a reservation from Delhi to Kolkata by staying in Mumbai or a flight from Canada to Singapore by van only. The speed of the van is slower than that of LAN and MAN.
Microsoft office
Introduction
Microsoft Office is a cluster of interconnected desktop applications and services, collectively called the Office Suite. Microsoft Office was first introduced for Mac-OS in 1989 by Microsoft Corporation. Then in 1990, the first version for Windows was introduced. Microsoft Office 3.0 was the first version of the Windows operating system of Office Suite. Then there are Microsoft Office 4.3, Microsoft Office 95, Microsoft Office 2000, Microsoft Office Agq and Microsoft Office 3003, Microsoft Office 2010. There are mainly four programs under Microsoft Office -
1. Microsoft Word
2. Microsoft Excel
3. Microsoft Access
4. Microsoft Power Point
These MS Office programs are used to perform different types of tasks, but they all have almost the same functionality. In which after learning to work on one program it becomes easy to learn other programs. Not only this, it is very easy to take any picture, material or information from one program of MS Office to another, so all kinds of mixed work can also be computerized with them.
Microsoft Word (Microsoft Word) -
Microsoft Word is a word processor developed by Microsoft Corporation. Its main function is to operate the document. It is a word processing package, with the help of which tasks from simple daily correspondence to desktop publishing level can be done conveniently. In addition to the traditional menus, the tool bar is also available. Such as copying, cutting, adding, searching and changing, checking font, spelling and grammar, bullets and numbering etc. In Microsoft Word 2007 and 2010, the facility to translate documents into different languages is also available.
computer viruses
Introduction A
computer virus is a program code that automatically enters the computer, prepared by an external source. The world's first computer virus was Elk Cloner, which was revealed by 'In the Wild'. This computer virus spreads through a floppy disk in the Apple DOS 3.3 operating system. A computer virus is a program that wreaks havoc on our computer, which damages your files and information present in the operating system without your knowledge or warning. The easiest way to spread computer viruses is the increasing use of network, Internet and e-mail. Generally computer virus can come in your computer in the following way-
1. using infected programs
2. using infected files
3. booting computers in disk drives with infected floppy disks
4. using pirated software
Computer viruses are not generated on their own, but these viruses are programs designed by people in their own discretion. Some people use it to protect their computer and some people prepare it for destruction. Types of computer viruses
There are many types of viruses, but most viruses are mainly divided into three parts -
1. Boot Sector
2. File Virus
3. Macro Virus
Important programming languages
Introduction
A computer is a machine and cannot understand our colloquial language. For this, programs are written in a particular type of language. These languages are known as programming languages. Nowadays hundreds of such languages are in circulation. These languages serve as a connection or communication between the computer and the programmer. The computer works by understanding the instructions given through them. Different languages are used for different tasks performed by a computer. Some of the major programming languages are as follows:
Low Level Languages:
Languages that are created keeping in mind the internal functioning of the computer are called low level languages. In this, the person writing the program needs to know the internal system of the computer. It is called low-level language because writing a program in it depends entirely on the computer on which it is being written. This language can be further divided into two other languages.
1. Machine Languages
A computer is a machine that can understand only electrical signals. These electrical signals are displayed by OFF or 0 (zero) and ON or 1 (one). These digits are called binary digits. The computer can only understand the instructions given in these binary digits. The language made of these binary digits is called machine language. Eg- 0100100011100110011
2. Assembly languages - Assembly
languages are languages that are based entirely on machine language. But instead of series of 0 and 1, some letters of English and some selected words are used as code. These codes are known as mnemonic codes or literal codes.
3. High Level Languages
As stated for the low-level language, it is necessary to have knowledge of the internal functioning of the computer in order to write the program. Second, each computer has its own separate machine language and assembly language. Therefore, a program written in these languages for one type of computer becomes useless for other types of computers. Therefore, such programming languages were developed which are not based on the internal functioning of the system and in which it is possible to run the programs written on any type of system. These languages are called high level languages. High-level programming language uses selected English words and symbols used in simple mathematics. Writing programs in these languages is easier to find and correct mistakes in them than in low level languages. All programs are written in high level language only.
High level programming languages can also be divided into two categories according to their nature.
1. Procedure Oriented Languages
2. Problem Oriented Languages
Major high-level language:
1. Basic
2. Fortran
3. Logo
4. COBOL
5. Pascal
6. C
7. C ++
8. Algol
9. Komal
10. Pilot
Llksnobol
12. Prologue
13. Fourth Generation Lagvej (4GL)
