IP Address

An IP address, short for Internet Protocol address, is an identifying number for network hardware connected to a network. Having an IP address allows a device to communicate with other devices over an IP-based network like the internet

What Is an IP Address Used For?

An IP address provides an identity to a networked device on the internet. Similar to a home or business address that supplies a specific physical location with an identifiable address, devices on a network are differentiated from one another through IP addresses.
If you send a package to a friend in another country, you have to know the exact destination. This same general process is used to send data over the internet. However, instead of using a physical mailing address, the computer uses DNS servers to look up a hostname to find its IP address.

Each type of IP address can be an IPv4 address or an IPv6 address.
  • Private IP Address: These are used inside a network, for example, a home network that is used by tablets, Wi-Fi cameras, wireless printers, and desktop PCs. These types of IP addresses provide a way for devices to communicate with a router and the other devices on the private home network. Private IP addresses can be set manually or assigned automatically by the router.
  • Public IP Address: These are used on the outside of a network and are assigned by an ISP. It's the main address that a home or business network uses to communicate with the rest of the networked devices around the world (for example, the internet). It provides a way for the devices in a home, for example, to reach an ISP, and therefore the outside world, allowing the devices to access websites and communicate directly with other computers and servers around the world.

Digital Transmission

Image
Data can be represented either in analog or digital form. The computers used the digital form to store the information. Therefore, the data needs to be converted in digital form so that it can be used by a computer. DIGITAL-TO-DIGITAL CONVERSION Digital-to-digital encoding is the representation of digital information by a digital signal. When binary 1s and 0s generated by the computer are translated into a sequence of voltage pulses that can be propagated over a wire, this process is known as digital-to-digital encoding. Digital-to-digital encoding is divided into three categories: Unipolar Encoding Polar Encoding Bipolar Encoding Unipolar Digital transmission system sends the voltage pulses over the medium link such as wire or cable. In most types of encoding, one voltage level represents 0, and another voltage level represents 1. The polarity of each pulse determines whether it is positive or negative. This type of encoding is known as Unipolar encoding as it ...

What is Topology?

Image
Topology defines the structure of the network of how all the components are interconnected to each other. There are two types of topology: physical and logical topology. Physical topology is the geometric representation of all the nodes in a network. Bus Topology The bus topology is designed in such a way that all the stations are connected through a single cable known as a backbone cable. Each node is either connected to the backbone cable by drop cable or directly connected to the backbone cable. When a node wants to send a message over the network, it puts a message over the network. All the stations available in the network will receive the message whether it has been addressed or not. The bus topology is mainly used in 802.3 (ethernet) and 802.4 standard networks. The configuration of a bus topology is quite simpler as compared to other topologies. The backbone cable is considered as a  "single lane"  through which the message is broadcast to all the st...

5(A) W ebsite Development Timeline When you think of building a website, your thoughts rotate around two main issues – price and time. These two values depend largely on the size and scope of the project. To outline the whole development process, you can create a website development timeline, adding tasks, and establishing milestones for your project. It is the best way to track your project implementation to make sure you keep up with the deadline. The Web Site Design and Development Process There are numerous steps in the web site design and development process. From gathering initial information, to the creation of your web site, and finally to maintenance to keep your web site up to date and current.  The exact process will vary slightly from designer to designer, but the basics are the same.  1. Information Gathering  2. Planning  3. Design  4. Development 5. Testing and Delivery  6. Maintenance 5(B) <div style="text-align:center;"> ...
