Showing posts with the label internet


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 happensin 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 23 = 8 and 24 = 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 point and preceding to the left or to the right…


We live in a world where every field requires use of computers.But computers need data to process the output.This data can be gathered with the help of internet.The internet uses World Wide Web to gather data.So the user must know the basics of the internet.So I am going to acknowledge the basic parts where and how the computer uses internet. I am going to discuss about OSI layers.
Osi means open system interconnectand was invented by ISO (INTERNATIONAL SYSTEM OF ORGANIZATION) which is an institution who manages giving standardization of the products to be manufactured.It was invented by iso in 1984.The use of iso in networking terms is to provide networking standardization of frame workfor implementing network protocols to be used in seven layers.
The seven layers breaks down the process of communication into smaller and easier to handle independent categories.Before osi different networking vendors couldn’t communicate with each other.After iso now different vendors have the abili…
