Important Short Notes On ICT For All Competitive Exams -Part -1

Computer:Computer is an electronic device which is used to store the data, as per given instructions it gives results quickly and accurately.

Main characteristics of a computer:
A computer is a programmable machine. The two main characteristics of a computer are:
  1. It responds to a specific set of instructions in a well-defined manner. 
  2. It can execute a pre-recorded list of instructions or a program.
Basic Concepts of Computer:
Data : Data is a raw material of information.
Information : Proper collection of the data is called information.

Characteristics of Computer:
The characteristics of computers that have made them so powerful and universally useful are speed, accuracy, diligence, versatility and storage capacity. Let us discuss them briefly.
  • SPEED : In general, no human being can compete to solving the complex computation, faster than computer.
  • ACCURACY : Since Computer is programmed, so what ever input we give it gives result with accuratly.
  • STORAGE : Computer can store mass storage of data with appropriate formate.
  • DILIGENCE : Computer can work for hours without any break and creating error.
  • VERSATILITY : We can use computer to perform completely different type of work at the same time.
  • MEMORY : It can save and store a large collection of data for us.
Computer and its components:
  1. Central Processing Unit (CPU): The ‘brain’ of the computer, the component that actually executes instructions.
  2. Memory : It enables a computer to store, at least temporarily, data and programs.
  3. Input device : Usually a keyboard or mouse is used to read data and programs into the computer.
  4. Output device: A display screen, printer, etc. that lets you see what the computer has accomplished.
  5. Mass storage device: It allows a computer to permanently store large amounts of data. Common mass storage devices include disk drive and tape drive.
Computer Software : Software is a logical program to handle/solve the complex problem.
Types Of Software:
  • System Software : This is special type of software which is responsible for handle the whole computer system.
  • Application Software : This is special type of software which is used to solve a particular problem.
  • Embeded Software : This type of software embeded with hardware to do a specific type of job.
  • Proprietary Software : In general, this type of software require to purchase to use that particular software for the some time or single user as per conditioned by the vendor of that particular software.
  • Open Source Software : This type of software may be freely available and can not be use in commercially. We can modify, and use it under the same license.
Functions and Components of a Computer:

To function properly, the computer needs both hardware and software.A computer does mainly the following four functions:

1. Receive input: Accept data/information from outside through various input devices like the keyboard, mouse, scanner, etc.
2. Process information: Perform arithmetic or logical operations on data/information.
3. Produce output: Communicate information to the outside world through output devices like monitor, printer, etc.
4. Store information: Store the information in storage devices like hard disk, floppy disks, CD, etc.

Computer Languages
Machine Level Language: This is low level programming language. Computer or any electronic device only understand this language. i.e. Binary number i.e 0 and 1.
Assembly Level Language: This is a low level programming language which is converted into executable machine code by a utility programmer referred to as an assembler.
High Level Language: High level language is a programming language which is easily understandable/readable by human.
Interpreter: This is a converter which converts high level language program to low level language program line by line.
Compiler: This is also a converter which converts whole high level language program to low level language program at a time.

Number System:
  1. Binary Number System : It has only base 2 i.e 0 and 1
  2. Octal Number System  : Base of octal is 8 i.e. 0, 1, 2, 3, 4, 5, 6, 7
  3. Decimal Number System : Base of Decimal is 10 i.e. 0 1 2 3 4 5 6 7 8 9
  4. Hexadecimal Number System : Base of this number system is 16 i.e. 0 1 2 3 4 5 6 7 8 9 A B C D E F
How the CPU and Memory work?

The working of the CPU and memory involves different steps for different tasks. let us consider steps involved in the multiplication of two numbers.
Step 1: The control unit recognizes that the program has been loaded into the memory. It begins to execute the first step in the program.
Step 2: The program tells the user, "Enter 1st Number".
Step 3: Suppose the user types the number 100 on the keyboard. An electronic signal is sent to the CPU.
Step 4: The control unit recognizes this signal and routes the signal to an address in memory - say address 7.
Step 5: After completing the above instruction, the next instruction tells the user,"Enter 2nd Number."
Step 6: Let us assume that the user types the number 4 on the keyboard. An electronic signal is sent to the CPU.
Step 7:  Now the control unit recognizes this signal and routes it to memory address 8.
Step 8:The next program instruction is executed - "Multiply 1st and 2nd Numbers."
Step 9: To execute this instruction, the control unit informs the ALU that two numbers are coming and the ALU is to multiply them. The control unit next sends to the ALU a copy of the contents of address 7 (100) and address 8(4).
Step 10: ALU performs the multiplication : 100 × 4 = 400
Step 11:  The control unit sends a copy of the multiplied result (400:) back to memory to store it in address 9.
Step 12: The next program instruction is executed : "Print the Result."
Step 13: To execute this instruction, the control unit sends the contents of the address 9 (400) to the monitor.
Step 14:  Monitor displays the value 400.
Step 15: Final instruction is executed: "End". The program is complete.

Brief Introduction of Computer Generation

9/07/2017 0
Brief Introduction of Computer Generation


Brief Introduction of Computer Generation: 


Generation in computer era provides a framework for the growth of computer industry and generally characterizes the major developments in the computer industry. The modern computer era can be divided into Five generations distinguished by the basic electronic component within the computer. Each new logic unit let the computers faster in speed, smaller in size, more reliable and less expensive than their predecessors. Modern computers came in a variety of shapes, sizes and


costs. Computers were developed in Five different phases known as the Generation of Computers.


Let’s discuss one by one in a little detail :





First Generation (1942-1955) 


The computers of this generation used Electronic Valves (an array of Vacuum Tubes) as the basic component for memory and circuitry for central processing unit. These vacuum tubes were a fragile glass device like electric bulb, that could control and amplify electronic signals. They produced a lot of heat and were prone to frequent fusing/ damaging of the installations. Therefore, they were used very expensive and could be afforded only by very large organizations.





Useful Points


• Period : 1942-1955


• Component used : Vacuum tubes


• Speed : milliseconds


• Maximum memory capacity : 2000 inch


• Mean-time before failure : minutes


• Peripherals : I/O : Punched cards, Paper tape, Magnetic tape, Printer (online) /  Secondary Storage : Punched Cards, Paper Tape, Magnetic Drum, Magnetic Disk etc 


• Operating System : Mainly Batch Processing


• Languages : Machine Code and Electric Wired board


• Application Areas : Payroll Processing, Record Keeping etc.


• Example : ENIAC, EDVAC, EDSAC and IBM 650 ( the first modern digital computer produced on


mass scale)





Second Generation (1955-1964) 


The second generation computer used Semi-conductor transistor instead of vacuum tubes after the invention of transistor by a team led by William Shockley. This generation computers used transistors which were cheaper, consumed less power, more compact in size, more reliable and faster than the vacuum tubes used in first generation computers.





Useful Points


• Period : 1955-1964


• Component used : Transistors


• Speed : microseconds


• Maximum memory capacity : 128000 inch


• Mean-time before failure : days


• Peripherals :


o I/O : Paper tape, Magnetic tape, Visual Display Unit


o Secondary Storage : Paper Tape, Magnetic Drum, Magnetic Disk etc


• Operating System : Multiprogramming, Time-Sharing and Real Time processing


• Languages : Assembly Language, High Level Languages like FORTRON, COBOL etc


• Application Areas : Batch –oriented application like Billing, Payroll processing, Updating


Inventory etc.


• Example : IBM 1401, IBM 7090, IBM 1620, IBM 7094, IBM 700 series, CDC 1604, CDC 3600,


UNIVAC 1108





Third Generation (1964-1975) 


The third generation computers used Integrated Circuits (or IC Chips) in which many transistors, resistors, capacitors and other components (circuit elements) are fabricated or integrated and packaged together into a very small surface of silicon known as Chips. This new microelectronic technology was called Integrated Circuits. The IC was invented by Jack Kilby in 1958





Useful Points


• Period : 1964-1975


• Component used : Integrated Circuits (IC)


• Speed : nanoseconds


• Maximum memory capacity : 4 million inch


• Mean-time before failure : weeks to months


• Peripherals :


o I/O : Typewriter terminal, Visual Display Unit, Optical Character Reader etc


o Secondary Storage : Magnetic Disk, Extended Core Storage, Mass Storage devices


• Operating System : Multiprogramming, Time-Sharing, Real Time processing and Remote


processing


• Languages : High Level Languages like FORTRON-II to IV , COBOL , BASIC, ALGOL-68,


PASCAL-1 etc


• Application Areas : Airline System, Market forecasting, Credit Card billing etc


• Example : IBM 360/370 series, ICL 1900 series, PDP 11, RCA Spectra 70 etc.





Fourth Generation (1975 onwards) 


Initially, the Integrated Circuits contained only about 10 to 20 components called Small Scale Integration (SSI). Later on with the advancement in technology for manufacturing Integrated Circuit Silicon Chips (ICS), it became possible to integrate up to a hundred components on a single chip called Medium Scale Integration (MSI). Now the manufacture of integrated circuits became so advanced as to incorporate hundreds of thousands of active components in volume of a fraction of inch, leading to Large Scale or Very Large Scale Integration (VLSI). Integrated Circuits which have the entire computer circuit on a single silicon chip are called Microprocessors. The development


of microprocessors made it possible to place complete CPU of a computer on a single chip.





The first Microprocessor Intel 4004 consisted of 2250 transistors on a microprocessor was designed by Intel Corporation engineer Ted Hoff in 1971. It was 4-bit microprocessor.





Useful Points


• Period : 1975 onward


• Component used : Very Large Scale Integrated Circuits (IC)


• Speed : picoseconds


• Maximum memory capacity : 200 million inch


• Mean-time before failure : months


• Peripherals :


o I/O : Visual Display Unit, Optical Character Reader, Magnetic Ink Character Reader, Voice Recognition, Laser Printer etc


o Secondary Storage : Floppy disk , Hard Disk, CD-ROM, DVD etc


• Operating System : Time-Sharing, Real Time processing and Network Distribution


• Languages : All High Level Languages like C, C++, Java and other 4th generation languages


(declarative languages used in Database )


• Application Areas : Mathematical Modelling, Simuation, Electronic Fund Transfer, Computer


Aided Manufacturing and Design etc


• Example : CRAY-1, CRAY-2, IBM 3090/600, IBM AS/400 HP 9000, IBM ES/9000, VAX etc





Fifth Generation (Future Generation: 1991 onwards ) : 


The fifth generation computers are under development stage. These computers will use Ultra Large Scale Integration (ULSI) chips instead of VLSI. These will be employing two or more processors which compute in parallel. The fifth generation machine are proposed to be based on Parallel Processing hardware and Artificial Intelligence software with genuine I.Q. (Intelligence Quotient). That provide the ability to reason logically and with real knowledge of the world like human do.


Characteristics of future generation computers :


i) Decreasing cost of hardware and software


ii) High speed processing


iii) Knowledge based processing system


iv) Development of natural language processing


v) Advancement in supercomputer technology


vi) Artificial Intelligence , think and behave like  human (humanoid)
