What is ip address and classes

An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

In the context of programming, a class is a template for creating objects. It is a way to define the structure of an object and the methods that will operate on it. Classes can contain variables and functions (also known as methods) that are used to manipulate the data stored in the object. When you create an object from a class, you are creating an instance of that class.





Ip address classes 

There are five classes of IP addresses: A, B, C, D, and E. These classes are defined based on the value of the first octet of the IP address, which determines the range of addresses available in that class.

Class A addresses have a range of 1.0.0.0 to 126.0.0.0 and are used for large networks.
Class B addresses have a range of 128.0.0.0 to 191.0.0.0 and are used for medium-sized networks.
Class C addresses have a range of 192.0.0.0 to 223.0.0.0 and are used for small networks.
Class D addresses are reserved for multicast groups and have a range of 224.0.0.0 to 239.0.0.0.
Class E addresses are reserved for experimental purposes and have a range of 240.0.0.0 to 255.0.0.0.
IP addresses are usually written in the form xxx.xxx.xxx.xxx, where xxx is a number between 0 and 255.

What is network

NETWORK TECH WORLD What is network  A network is a group of devices, such as computers, servers, and printers, that are connected together and able to communicate with each other. Networks can be classified based on their size and scope, such as a local area network (LAN), which is a network that is confined to a small area, such as a single building or campus, or a wide area network (WAN), which is a network that spans a large geographical area, such as a city or a country. Networks can also be classified based on their communication protocols, such as the Internet, which is a global network that uses the Internet Protocol (IP) to connect devices around the world.

Network Devices

NETWORK TECH WORLD A network device is a hardware device that helps to connect a computer or other devices to a network. There are several types of network devices, including: Routers: These devices route data packets between different networks. Switches: These devices allow multiple devices on a network to communicate with each other by forwarding data packets to the intended recipient. Hubs: These devices are similar to switches, but they do not filter the data packets based on the destination. Instead, they broadcast the data packets to all devices connected to the hub. Bridges: These devices connect two different networks and allow data packets to be transmitted between them. Modems: These devices allow computers to connect to the internet by converting data into a format that can be transmitted over a phone line or cable connection. Firewalls: These devices protect a network by blocking unauthorized access and monitoring traffic for any malicious activity. These are just a few exa...

How to Hack Computer

NETWORK TECH WORLD  How to Hack Someone's Computer As the digital world becomes more and more complex, the need for deliberate, thorough security grows. Yes, we know, you’ve got everything “password protected.” And yes, not every hacker is like the guys in the movies who are able to keyboard their way through complicated layers of encrypted, password-protected security faster than a gamer boots up a new version of Call of Duty. In the real world it’s a lot easier than that. And no, this isn’t actually a tutorial about how to break into someone’s computer or smart phone or tablet. Just an observation of sorts. A caution to our loyal readers, if you like. The Brand Keys 2012 Customer Loyalty Engagement Index reveals that consumers choose laptop computers on the basis of anything but security. Instead, consumers tend to select on the basis of factors like innovative design and brand reputation. This doesn’t mean that security isn’t important, but that it does mean that it’s...
