Network Protocols

NETWORK TECH WORLD


A network protocol is a set of rules and standards that define how devices on a network should communicate with each other. Network protocols govern everything from the type of cable that is used to connect devices to the way in which data is transmitted between them.

There are many different types of network protocols, each of which serves a specific purpose. Some common examples include:

TCP (Transmission Control Protocol): This is a connection-oriented protocol that is responsible for breaking up data into packets, transmitting the packets over the network, and reassembling the packets at the destination. TCP is a reliable protocol that ensures that all packets are delivered to their destination.

IP (Internet Protocol): This is a connectionless protocol that is responsible for routing packets between devices on a network. IP is an unreliable protocol that does not guarantee that packets will be delivered to their destination.

HTTP (Hypertext Transfer Protocol): This is a protocol that is used to transmit data over the World Wide Web. It is the foundation of the modern web and is used to send and receive HTML pages.

FTP (File Transfer Protocol): This is a protocol that is used to transfer files between devices on a network. FTP allows users to transfer files between their own device and another device, or to download files from a server.

SMTP (Simple Mail Transfer Protocol): This is a protocol that is used to transmit email messages between servers. SMTP is responsible for sending, receiving, and routing email messages.

There are many other network protocols in addition to these, each of which serves a specific purpose in the operation of a network.

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...
