Global Variable: It is a variable that is generated outside a module. This global variable can be accessed from anywhere within a program . Scope of a global variable: Scope is nothing but the accessibility of a variable. A variable is visible to the statements present in the variable’s scope. It is possible to access the global variable outside the module and also by other modules.

Computer Science A Caesar cipher is one of the simplest forms of encryption. It is a substitution cipher where each letter in the plaintext is shifted a certain number of places down the alphabet. For example, with a right shift of 3, 'A' would be replaced by 'D', 'B' would become 'E', and so on. The alphabet "wraps around," so with a shift of 3, 'X' would become 'A'. Your task is to implement this logic. 1. Develop a set of functions to encrypt a string using a Caesar cipher. 2. Develop a set of functions to decrypt a string using a Caesar cipher. 3. Develop a set of functions to help solve (break) a Caesar cipher by showing all possible shifts.4. Implement all of the above functions for TWO of the following languages: Encrypt, Decrypt, Solve in COBOL Encrypt, Decrypt, Solve in Fortran Encrypt, Decrypt, Solve in Pascal Examples of Usage The usage for encrypt and decrypt should be as follows: encrypt(str, shiftAmount) decrypt(str, shiftAmount) Pascal code fragment: var x: string;…

No AI USE PLEASE. You are using a web browser to load a webpage. Let’s assume the size of the webpage is negligible. The access link rate of the webserver is 1 Gigabits per second. The IP address for the associated URL is not cached in your local host, so a DNS lookup is necessary to obtain the IP address. Suppose that n DNS servers are visited before your host receives the IP address from DNS; the successive visits incur an RTT of RTT1, . . . , RTTn. Let RTT0 denote the RTT between the local host and the webserver containing the webpage. Now answer the following: 1) Ignore all types of delays at the client and the servers. How much time elapses from when the client clicks on the link of the webpage until the client receives the content of the webpage? 2) Now suppose, the HTML file references 10 additional objects (15 MB each) on the same server. Considering only the transmission delay at the webserver for each of these objects and ignoring all other delays at the host and the servers,…
