An exe is an executable program while a DLL is a file that can be loaded and executed by programs dynamically. It is an external code repository for programs. As both are different programs, reuse the same DLL instead of having that code in their file. It also reduces required storage space.
A firewall works by protecting your network from potentially dangerous data packets. It is available both as software and as hardware already built into most modern routers. An antivirus, instead, detects malware that is already in your system and limits the damage to your computer by deleting or isolating the infected files. To put it briefly, a firewall protects your system from malware infections, while an antivirus removes the malicious software.
ASCII stands for American Standard Code for Information Interchange. It is a widely used format for text files on computers. The basic ASCII table includes 128 characters, but extended ASCII adds 128 characters, so the total is 256. Its purpose is to ensure that different devices can communicate with each other. Also, it translates the binary language of a computer into human language, so you can read it on the screen.
An IP address is a unique number that identifies a device connected to the network. Exactly like your home address, it provides information about a specific physical location. There are two versions of the IP protocol: IPv4 and IPv6. IPv6 is replacing IPv4 because it allows trillions of devices to connect to the network, and it has built-in security features. There are private and public IP addresses. The former connect devices in a private home or company network, while the latter allows the devices to connect with other computers and servers all over the world.
HTTP stands for HyperText Transfer Protocol. It is a network protocol used by the internet to fetch and display the web page you are looking for or to let you skip from one page to the other. However, HTTP protocol is designed in plain text, so any other person in the network could potentially see the data that your browser communicates to the server and vice versa. HTTPS, instead, uses the Secure Sockets Layer (SSL), which encrypts your data to keep it secure.
