TYPE OF NETWORK

On the basis of geographical area and speed there are three broad categories of network
1.  LAN (Local Area Network)
2.  MAN ( Metropolitan Area Network)
3.  WAN ( Wide Area Network)
  LAN(Local Area Network): LAN is a type of network in which computers (nodes) are connected in a local unit or small geographical area, such as office, any department of a management system, Private Campus etc. The common connecting media used in LAN are cables, Wi - Fi, etc. LANs are restricted in size and are convenient to handle.
Characteristics of LAN
i)In LAN, Data communication takes place at a rate of 100 – 1000 mbps.
ii)   It is owned by an individual or an organization
iii) It provides the user with an access to share several common hardware resources. Ex- computers, terminals, printers, server, etc.
iv)There is no specific tariff for its usage.
MAN (Metropolitan Area Network)
MAN is a computer network designed for a town or city. It may be a single network or may be a network that connects several LANs. MAN may be operated by a single organization or by several organizations in the same city. Ex- telephone lines, networking of a MNC, networking of various government departments, etc. The communication media used in MAN can be wired or wireless.
Characteristics of MAN:
i) It covers larger than LAN but smaller geographical area than WAN.
ii) It is surrounded within a single city ot metropolitan area.
iii) It is mainly owned by large Organizations to interconnect all its branch across a city.
                       
   WAN (Wide Area Network)
WAN is a type of network in which computers are connected over large geographical area such as cities, states, countries or even the whole world. Its purpose is establish connection to share information among computers from one place to other globally.
The common example of WAN is “INTERNET”, The communication medium used in WAN is mainly unguided media (satellites).
Characteristics of WAN
i)   The speed of data transfer is up to 150mbps.
ii)  It connects large geographical area at low cost.
iii)WAN between two or more network are connected through ‘GATEWAY’ that establish connectivity between protocol used in one network with the other network.

These Two more types of network used in now-a-days:
PAN (Personal Area Network)
PAN is a computer network that is functional around an individual or is limited within a range of 10 meters. It is an interconnection of several peripherals or devices such as laptop, smartphone, printers, etc.
   Such Personal Area Network can be wired or wireless. Bluetooth, Infrared are common examples of PAN. Bluetooth’s PAN are also known as ‘Piconets’.

CAN (controller Area Network)
Controller Area Network is an ISO certified method of communication between various electronic devices used for lighting control, air conditioning, airbags, central locking embedded in a vehicle etc.

Computer Generations

 Computer Generations   Computers have evolved over time through different generations, each marked by significant technological advancements and changes in design and architecture. These generations are often categorized based on the underlying hardware and the key developments that distinguish one Generation from another. Let's explore the main computer generations: First Generation Computers    The First Generation of computers refers to the initial period of electronic computing, characterized by the use of vacuum tubes as the primary electronic component. This Generation spans the 1940s and 1950s and is marked by groundbreaking developments in computer technology.  Examples of First-Generation Computers:  o ENIAC (Electronic Numerical Integrator and Computer): Completed in 1945, ENIAC was one of the first electronic general-purpose computers. It was designed to calculate artillery firing tables for the United States Army during World War ...

Programming in "C"

 Introduction   C is a general-purpose programming language that was developed in the early 1970s by Dennis Ritchie at Bell Laboratories. It has since become one of the most widely used programming languages and has influenced the development of many other languages, including C++, Java, and C#. C is known for its efficiency, flexibility, and low-level programming capabilities. It is commonly used for system programming, embedded systems, and developing operating systems. C is also a popular choice for developing applications that require high performance, such as game engines and scientific simulations.   Here are some key features and concepts of C programming:   Syntax: C has a relatively simple syntax compared to some other programming languages. It uses a combination of keywords, variables, data types, operators, and control structures to write programs.  Variables and Data Types: You declare variables to store data in C. Various d...

ARITHMETIC OPERATIONS ON BINARY NUMBER

Binary arithmetic is simpler to learn because binary number system deals with only two digits - 0 and 1. Binary number perform all arithmetic operation such as Addition, Substraction, Multiplication and compliment as in decimal number system. Binary Addition The addition table for binary arithmetic consist of only the following four entries: 0+0=0 0+1=1 1+0=1 1+1=0 , plus a carry of 1 to the next column.     1011        + 1100    10111     1100    + 1100     11000 Binary Substraction There are three ways to do substraction between binary numbers:- 1. Simple Substraction 2. Substraction using 1's Complement 3. Substraction using 2's Complement Simple Substraction: The complete table of binary substraction is as follows: 0-0=0 0-1=1, borrow 1 from next column 1-0=1 1-1=0    1101 - 0101   1000     1001   - 0111    0...
