SUMMARY OF AN OUTPUT DEVICE KNOWN AS INKJET PRINTER

Image
INKJET PRINTERS THE MOST POPULAR TYPE OF PRINTER IN TODAYS MARKET IS INKJET PRINTER.  IT USES A RESERVIOR OF INK, A PUMP AND A NOZZLE.  IT WORKS EFFECIENTLY AND T IS THE CHEAPEST PRINTER IN THE MARKET STARTING 1800 BUT THE PRINTER COST IS HIGHCOMPARING TO OTHERS TYPE OF PRINTER. IT SPRAYS THE LIQUID INK ON TO A PAPER ACCORDING TO THE PATTERN OF PRINTED   DOCUMENTS.  IT SUPPORTS VERY HIGH DEFINATION OF THE DOCUMENT TYPES. PARTS OF INKJET PRINTER :- INKJET PRINTER ARE SIMPLE DEVICE.  THEY CONTAINS VERY FEW PARTS.  THEY ARE INEXPENSIVE AND EASILY AVAILABLE IN THE MARKET.THE PARTS CAN BE DIVIDED INTO THE FOLLOWING CATEGORIES  1) PRINT HEAD OF INK CARTRIDGE-->  IT CONTAINS LIQUID INK AND TWO HUNDRED TINY NOZZLES TO SPRAY THE INK IN SMALL DROPLETS. MANY TIMES A PRINTER MAYCONTAIN A RESERVOIR OF INK.  MOST COMMON COLOURS ARE USED INTO SEPARATE CARTIDGE ONE FOR BLACK AND ANOTHER ONE FOR CYAN, MAGENTA AND YELLOW.  THERE ARE TWO METHODS OF SPRAYING THE INK. • THERMAL BUBBLE --> IT IS

UNDERSTANDING THE COMPUTER REGISTERS.

 REGISTERS AND ITS USES IN COMPUTER WORLD. “In this life, all we have is memory! ” This exclamatory sentence is used by many film makers in their dialog.  So does it actually mean something to them?  Yes it definitely means everything to them and us.  That’s why they show them in their cinema (movie, film whatever you say).  Memories mean everything that is stored in our brain after we experience it and then use it as a lesson for life  or entertainment purpose. Humans as well as all living beings do that.  But our topic is  “WHAT ARE REGISTERS? WHY DO COMPUTERS NEED THEM?” So here we begin. The discrete elements of information in a digital computer must have a physical existence in some information storage medium.  Furthermore, when discrete elements  of information are represented in binary form, the information storage medium must contain binary storage elements for storing individual bits.   A binary cell is a device that possesses two stable states and is capable of storing one bi

HOW DO COMPUTERS UNDERSTAND BINARY LOGIC

  HOW DO COMPUTER UNDERSTAND THE BINARY LOGIC?   As we have shown in the previous post  LANGUAGE THAT COMPUTER AS WELL AS HUMAN UNDERSTAND  I am going to dig deep of that topic in this post.  I will try to explain how computer understand the binary logic.   So lets begin.   I am going to write about binary logic, that most of the computer manufacturers and developers use.                  Binary logic deals with variables that take on two discrete values and with operations that assume logical meaning.   The two values the variables take may be called by different names (e.g. true and false, yes and no, etc.), but for our purpose it is convenient to think in terms of bits and assign the values of 1 and 0.     Binary logic is used to describe, in a mathematical way, the manipulation and processing of binary information.   It is particularly suited for the analysis and design of digital systems.   For example, the digital logical circuits of many circuits that perform binary

TYPES OF NETWORK TOPOLOGY NETWORK TOPOLOGY IS THE SCHEMATIC DESCRIPTION OF NETWORK ARRANGEMENT, CONNECTING VARIOUS NODES (SENDER AND RECEIVER) THROUGH LINES OF CONNECTION.   BUS TOPOLOGY BUS TOPOLOGY IS A NETWORK TYPE IN WHICH EVERY COMPUTER AND NETWORK DEVICE IS CONNECTED TO A SINGLE CABLE.   WHEN IT HAS EXACTLY TWO END POINTS, THEN IT IS CALLED LINEAR BUS TOPOLOGY.   FEATURE OF BUS TOPOLOGY 1.        IT TRANSMITS DATA ONLY IN ONE DIRECTION 2.        EVERY DEVICE IS CONNECTED TO A SINGLE CABLE.   ADVANTAGES OF BUS TOPOLOGY 1.        IT IS COST EFFECTIVE CABLE REQUIRED IS LEAST COMPARED TO OTHER NETWORK TOPOLOGY. 2.        USED IN SMALL NETWORKS 3.        IT IS EASY TO UNDERSTAND 4.        EASY TO EXPAND JOINING TWO CABLES TOGETHER.   DISADVANTAGES OF BUS TOPOLOGY 1.        CABLE FAILS THEN WHOLE NETWORK FAILS. 2.        IF A NETWORK TRAFFIC IS HEAVY OR NODES ARE MORE THE PERFORMANCE OF THE NETWORK DECREASES. 3.        CABLE HAS LIMITED LENGTH

ARITHMETIC CALCULATION IN COMPUTERS

ARITHMETIC OPERATION AND CONVERSION DONE BY COMPUTER As we have seen in previous post that arithmetic computation is an important thing in calculation, if a person doesn’t know arithmetic computations,   he will be doomed to be in trouble during calculations that happens   in everyday life.   So it is necessary to learn arithmetic computation.   So in this post I am going to take one step further.   I am going to write about octal and hexadecimal numbers. Now let us discuss some arithmetic conversion.   Let us see what is octal and hexadecimal numbers used by digital computer. The conversion from and to binary, octal and hexadecimal plays an important part in digital computers.   Since 2 3 = 8 and 2 4 = 16 each octal digit corresponds to three binary digits and each four binary digit corresponds to one hexadecimal digit.   The conversion of from binary to octal is easily accomplished by partitioning the binary into group of three digit each, starting from binary

MATHEMATICS AND COMPUTER SCIENCE RELATIONSHIP

MATHEMATICS AND COMPUTER SCIENCE RELATIONSHIP. In today’s world mathematics is a must learned subject .   In all the inventions and discovery , the main reason for their success of the practical’s are due to mathematics.   So in order to make a career in today’s world require mathematics.   But this Is blog of computers science and information technology, then why should we read mathematics so it requires mathematics to understand the reason behind such technology.   So I am going to write something about mathematics for its uses and technology in the computer world. One of the main aims of logic is to provide rules by which one can determine whether any particular argument or reasoning is valid (correct) Logic is concerned with all kinds of reasoning whether they be legal arguments or mathematical proofs or conclusions in a scientific theory based upon a set of hypothesis.   Because of the diversity of their application these rules are called rules of inference,
