Introduction of Computer

.

 A computer is an electronic device. It take input and store the data in memory and performing the function to produce accurate result in output device. It is used to type document, send email, play game, browse the web and entertainment. 

Characteristics of computer 

1. High speed 

  • Computer is very fast device.
  • It is capable of performing calculation of very large amount of data.
  • The computer has unit of speed in microsecond, nanosecond and even in picosecond.
  • The computer is capable of performing millions of tasks per second.
2. Accuracy 

  • The computer produces highly accurate and reliable result.
  •  It does not make any kind of mistake in calculating.
  • The calculation are 100% error free.
  • The computers perform accurate 'n' number of times.

3. Storage capability

  • A computer has much more storage capability.
  • It can store large amount of data.
  • It can store any type of data such as image, video, text document, audio and many more.
4. Diligence

  • Diligence means that the computer is capable of doing any work for a long time without getting tired and getting stops.
  • It can works continuously without any error.
  • Unlike human beings, a computer is free from tiredness and lack of connection.

5. Versatility

  • A computer is capable of performing a wide variety of function.
  • Computer can be used to solve the problems related to various field.

Introduce Linux, UNIX and Linux distribution.

 . Linux Linux is an open source operating system. The term Linux is actually referred to mean a kernel of Unix like operating system developed by a Finish software architect Linus Torvald. The name Linux is derived from Linus' Unix. Linux was originated from the inspiration of a small Unix like operating system MINIX by A.S Tanenbum. Linux is a complete multiuser, multiprocessing, secure and stable operating system which is also considered as UNIX clone. However no code from the proprietary from AT and T is included in Unix. It has flavor of Unix but is not Unix. UNIX  UNIX is a layered operating system. The innermost layer is the hardware that provides the service for the OS. The operating system, referred to in UNIX as the kernel, interacts directly with the hardware and provides the services to the user program. These user programs don't need to know anything about the hardware. They just need to know how to interact with the kernel and it's up to the kernel to provide ...

Define LAN and WAN

 . Local Area Network (LAN)  A LAN is a network that is used for communicating among computer devices, usually within an office building or home.   LAN’s enable the sharing of resources such as files or hardware devices that may be needed by multiple users • • Is limited in size, typically spanning a few hundred meters, and no more than a mile.  Is fast, with speeds from 10 Mbps to 10 Gbps.  Requires little wiring, typically a single cable connecting to each device.  Has lower cost compared to MAN’s or WAN’s.  LAN’s can be either wired or wireless. Twisted pair, coax or fiber optic cable can be used in wired LAN’s. Advantages of LAN :    The data is transferred at an extremely faster rate in local Area Network.  Local area network (LAN) provides higher security. Disadvantages of LAN :   Initial cost of installing local area network is quite high.  Unauthorized user can access critical data of an organization in case LAN ad...
