Graphical User Interface

GUI stands for Graphical User Interface. It provides a graphical interface for the user to interact with the computer. It was developed in the late 1970s by the Xerox Palo Alto research laboratory and deployed commercially in Apple's Macintosh. Graphical user interfaces would become the standard of user centered design in software application programming, providing users the capability to intuitively operate computers and other electronic devices through the direct manipulation of graphical icons such as buttons, scroll bar, windows, tabs, menus, cursors and mouse.

Example of GUI are Microsoft Windows, macOS, Ubuntu Unity and GNOME Shell for desktop environments and Android, Apple's iOS, BlackBerry OS, Windows 10 Mobile, Palm OS-WebOS and Firefox OS for smartphones.

Feature and advantage of GUI

  • Non technical convenience
  • Drag and drop function
  • It looks better than a text interface
  • Use easy to understand words for user type
  • Easy to use
  • People with disabilities
  • Have a Reference document.

Disadvantage of GUI

  • High costs, complexity in development
  • Slower than command line programs
  • Special attention is required
  • Use a flat screen

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 ...

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 ...

Open System Interconnect (OSI) Reference Model

 . Open system interconnection (OSI) Model explains how packet travels through various layers to other devices on a network, even if the sender and destination have different types of network media. Layer 1(Physical layer):  Function  To activate, maintain, deactivate the physical connection.  To define voltage and data rates needed for transmission.  To convert the digital bits into electrical signals.  To decide weather the transmission the transmission is simplex, half or full duplex.  Physical layer doesn’t perform the detection and correction of errors. Layer 2 (Datalink layer):  Framing (stream of bits into manageable data units):  The datalink layer divides the stream of bits received from the network layer into frame manageable data units called frames.  Physical addressing (MAC Address):  Data link layer adds a header to header to the frame to define the sender and receiver of the frame. Flow Control (mechanism for overwhel...
