Q. What is Computer ?



BY RAJNISH KUMAR


Computer is an electronic device that is designed to work with Information. The term computer is derived from the Latin term ‘computare’, this means to calculate or programmable machine. Computer can not do anything without a Program. It represents the decimal numbers through a string of binary digits. The Word 'Computer' usually refers to the Center Processor Unit plus Internal memory.

Charles Babbage is called the "Grand Father" of the computer. The First mechanical computer designed by Charles Babbage was called Analytical Engine. It uses read-only memory in the form of punch cards.

Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.



Digital Computer Definition

The basic components of a modern digital computer are: Input Device, Output Device, Central Processor Unit (CPU), mass storage device and memory. A Typical modern computer uses LSI Chips.  

Four Functions about computer are



Input (Data):

Input is the raw information entered into a computer from the input devices. It is the collection of letters, numbers, images etc.

Process:

Process is the operation of data as per given instruction. It is totally internal process of the computer system.

Output:

Output is the processed data given by computer after data processing. Output is also called as Result. We can save these results in the storage devices for the future use.

Computer Classification: By Size and Power
Computers differ based on their data processing abilities. They are classified according to purpose, data handling and functionality.

According to functionality, computers are classified as:

• Analog Computer: A computer that represents numbers by some continuously variable physical quantity, whose variations mimic the properties of some system being modeled.

• Personal computer: A personal computer is a computer small and low cost. The term "personal computer" is used to describe desktop computers (desktops).

• Workstation: A terminal or desktop computer in a network. In this context, workstation is just a generic term for a user's machine (client machine) in contrast to a "server" or "mainframe."

Minicomputer: A minicomputer isn't very mini. At least, not in the way most of us think of mini. You know how big your personal computer is and its related family.

Mainframe: It refers to the kind of large computer that runs an entire corporation.

• Supercomputer: Itis the biggest, fastest, and most expensive computers on earth.

• Microcomputer: Your personal computer is a microcomputer.

Block Diagram of Computer and Explain its Various Components
BY Rajnish Kumar

A computer can process data, pictures, sound and graphics. They can solve highly complicated problems quickly and accurately. A computer as shown in Fig.  performs basically five major computer operations or functions irrespective of their size and make. These are
1) it accepts data or instructions by way of input,

2) it stores data,

3) it can process data as required by the user,

4) it gives results in the form of output, and

5) it controls all operations inside a computer.

We discuss below each of these Computer operations

  Block Diagram of Computer and Explain        its Various Components

                 

                                                             Fig : Basic computer Operations



1. Input: This is the process of entering data and programs in to the computer system. You should know that computer is an electronic machine like any other machine which takes as inputs raw data and performs some processing giving out processed data. Therefore, the input unit takes data from us to the computer in an organized manner for processing.




2. Storage: The process of saving data and instructions permanently is known as storage. Data has to be fed into the system before the actual processing starts. It is because the processing speed of Central Processing Unit (CPU) is so fast that the data has to be provided to CPU with the same speed. Therefore the data is first stored in the storage unit for faster access and processing. This storage unit or the primary storage of the computer system is designed to do the above functionality. It provides space for storing data and instructions. 

The storage unit performs the following major functions:

• All data and instructions are stored here before and after processing.

• Intermediate results of processing are also stored here.

3. Processing: The task of performing operations like arithmetic and logical operations is called processing. The Central Processing Unit (CPU) takes data and instructions from the storage unit and makes all sorts of calculations based on the instructions given and the type of data provided. It is then sent back to the storage unit.

4. Output: This is the process of producing results from the data for getting useful information. Similarly the output produced by the computer after processing must also be kept somewhere inside the computer before being given to you in human readable form. Again the output is also stored inside the computer for further processing.

5. Control: The manner how instructions are executed and the above operations are performed. Controlling of all operations like input, processing and output are performed by control unit. It takes care of step by step processing of all operations inside the computer.

FUNCTIONAL UNITS
In order to carry out the operations mentioned in the previous section the computer allocates the task between its various functional units. The computer system is divided into three separate units for its operation. They are

1) arithmetic logical unit

2) control unit.

3) central processing unit.

Arithmetic Logical Unit (ALU)  

Logical Unit :After you enter data through the input device it is stored in the primary storage unit. The actual processing of the data and instruction are performed by Arithmetic Logical Unit. The major operations performed by the ALU are addition, subtraction, multiplication, division, logic and comparison. Data is transferred to ALU from storage unit when required. After processing the output is returned back to storage unit for further processing or getting stored.

Control Unit (CU)

The next component of computer is the Control Unit, which acts like the supervisor seeing that things are done in proper fashion. Control Unit is responsible  for  co ordinating various operations using time signal. The control unit determines the sequence in which computer programs and instructions are executed. Things like processing of programs stored in the main memory, interpretation of the instructions and issuing of signals for other units of the computer to execute them. It also acts as a switch board operator when several users access the computer simultaneously. Thereby it coordinates the activities of computer’s peripheral equipment as they perform the input and output. 

Central Processing Unit (CPU) 
The ALU and the CU of a computer system are jointly known as the central processing unit. You may call CPU as the brain of any computer system. It is just like brain that takes all major decisions, makes all sorts of calculations and directs different parts of the computer functions by activating and controlling the operations.

Vaise ek sach baat bata du toh facebook ne apni security ko bahut hi strong kar diya hai.Isliye jab koi bruteforce attack kar ke password pata lagane ki koshish karta hai toh facebook usse 5-6 baar try karne ke baad kuch time ke liye block kar deta hai.Or toh or facebook aapki ip address ko detect kar leta hai.Yeh sab pata hone ke karan hi mai is topic par post share nai kar raha tha.But hamare kuch readers ne bahut request ki hai ki is bare me jankari share ki jaye.Toh yeh post un readers ke liye jo Bruteforce and dictionary attack ke bare me jana chahte hai.


Dictionary Attack Kya Hai - What Is Dictionary Attack

  • Dictionary attack me karna kya hota hai ki hame ek password list banani padti hai.For example aap apne kisi friend ka facebook account hack karna chahte hai.Toh aapko sab se pehle Ek list banani hogi ki voh kaise kaise password rakh sakta hai.Jaise ki aapko pata hai ki aapka friend mobile number hi rakh sakta hai password me toh Aap ek aisi text list ready karege jisme uske 5-6 mobile number ho.Or fir us mobile number ki list se Aap facebook par direct attack karege.Yeh puri process ko dictionary attack kehte hai.Jo Softwares and plugins ke dwara possible hai.
  • Jaise jaise ham post ko practically aage badhayege vaise vaise aapko samajh me aata jayega ki dictionary attck kya hai.Or dictionary attack hota kaise hai.So keep reading and enjoying the post !

How Dictionary Attack Works :

  • Jese keh me ne bataya keh dictionary attack mein aik file hoti hein jis mein kuch passwords hote hein un passwords ko aik aik kar ke victim ke account pe try kia jata hai aur agar victim ka password un mein se aik hai to uska account hack ho jaye ga.Ab aap ye soch rahe hoo ge keh hum aik aik password kese try kare ge yani iss mein to hum ko bohat saara time lage ga.Dosto aisa nahi hai keh hum khud wo passwords aik aik kar ke victim ke account par daalte hein balkeh baat kuch yoo hai keh hum wo passwords machine se aik aik kar ke victim ke account pe try karte hein aur aik second mein victim ke account pe 10 se 20 passwords check kiye jaate hein.

Brute Force Attack Kya Hai - What Is Brute Force Attack

  • Dosto,Is method me hota kya hai ki isme pehle se hi lambi list bani hui hoti hai random characters ki ,names ki,numeric combination ki,etc aur ye bari bari se sabhi combinations ko try karta hai ,agar koi bhi combination match kar jata hai to aapka password crack ho jata hai.Bruteforce attack kitne time lega ek password ko hack karne me ye computer ki speed aur password ki complexity par depend karta hai.
  • Bruteforce attack passwords ko hack karne ka aik aisa attack hai jis mein hum koi bhi file use nahi karte hein.Iss mein hur possible password ko victim ke account pe try kia jata hai.Bruteforce attack mein victim ka password 100% hack hota hai lekin depend karta hai keh iss pe kitna time lage ga.
  • Aisi alag alag password check karne me software ko kaafi time lag sakta hai.Agar password easy hoga toh jaldi toot jayega.Lekin hard hoga toh kuch keh nai sakte.Aage hame practically bruteforce attack kar rahe hai.

How Bruteforce Attack Works :

  • Maan lijye me aik wpa2 security ya phir wpa security waale aik wifi ko hack karna chahta hoo.Ab sub ko ye pata ho ga keh wpa ya wpa2 security waale wifi mein 8 words ka password use hota hai.Ab uss password mein letters bhi ho sakte hein digits bhi ho sakte hein aur uppercase and lowercase letters bhi ho sakte hein.Ab me iss type ke wifi ko hack karne ke liye bruteforce attack ko use karuga.
  • Bruteforce attack mein hoga kuch aise ki koi file to use nahi ki jaye gi lekin bruteforce attack karne ke liye jo tool hum use kare ge wo pehle hum se pooche ga keh aap kitne words ka password hack karna chahte hein.Ab me wifi hack kar raha hoo jis ka password 8 words ka hai to me iss software ko kaho ga keh mujhy 8 words ka password hack karna hai.Ab ye software kya kare ga keh 8 letters ke jitne bhi words bante hein un sub ko baari baari uss wifi pe try kare ga aur un me se 8 words ka aik password uss wifi ka bhi ho ga.
  • Dictionary Ya Bruteforce Attack Karne Ka Sab Se Aasaan Tarika

    Jaise maine pehle kaha ki bruteforce attack karne ke liye aapke paas programming language and coding ki knowledge honi chahiye.Internet par bhi iske bare me bataya gaya hai lekin sabhi me coding ya kali linux ki jarurat padti hai.Agar mai bhi aapko aise hi methods se samjhata toh bruteforce attack ko practically samjhna aapke liye mushkil ho jata.Isliye maine Bruteforce attack se facebook hack karne ka sab se aasan tarika dhund nikala hai.

    STEP 1 : Download Browser And Plugin
    • Aapko sab se pehle jarurat padegi computer ki.Computer aa jane ke baad usme mozilla firefox install karna hai.Agar pehle se pc me hai toh install mat kariye.Click Here To Download FireFox Browser.
