Since an after-school care center allows children to browse the internet, the term that network hosts would most likely provide of this service is option  A: Proxy server

A system or router known as a proxy server acts as a gateway between users and the internet. Thus, it aids in preventing online attackers from accessing a private network.

Therefore, in the case above, A proxy server serves as a mediator between a computer and the internet because it has its own IP address. Your computer is aware of this address, and when you send a request over the internet, it is forwarded to the proxy. The proxy then receives the response from the web server and passes the page's data to your computer's browser, such as Chrome, Safari, Firefox, or Microsoft Edge.

The method that will be easiest for you to use when retrieving the password is a brute force attack. The correct option is a.

Using a predetermined set or list of widely used passwords or from a database leak, a brute attack is a technique for cracking someone's password or login credentials.

By utilizing a mix of a password devoid of dictionary words and several symbols and numbers with both uppercase and lowercase characters, we can guard against brute-force attacks.

This is the kind of hacking where an algorithm or machine repeatedly tries different password combinations and sequences until it finds the proper one.

A block cipher encrypts one byte (or bit) at a time, whereas a stream cipher encrypts an entire block of data at a time is true.

Using a cryptographic key and algorithm, a block cipher encrypts data in blocks to create ciphertext. A stream cipher encrypts data one bit at a time, as opposed to the block cipher, which processes fixed-size blocks simultaneously.

Therefore, note that while stream ciphers change plaintext into ciphertext one byte at a time, block ciphers transform plaintext one block (64/128/256 bits) at a time. Block ciphers become slower as a result since a whole block must be gathered before the data can be encrypted or decrypted.

hasEmpty = false;

for (int i = 0; i < names.length; i++)

if (names[i] == null || names[i].length() == 0)

hasEmpty = true;

An array of arrays of characters is an array of arrays of strings. Here, the terms “string array” and “arrays of strings" are synonymous. You can use arrays of strings, for instance, to store the names of students in a class. String arrays might have one dimension or several dimensions.

A string is a particular kind of variable that holds a collection of characters (i.e. text.) A boolean is a type of variable that can take on either the true or false value.In some circumstances, we must set the boolean array's initial values to either true or false.

Only boolean data types can be stored in the boolean array, and the array's default value is false. Arrays of reference types are initialized to null, while arrays of booleans are initialized to false.

Therefore, if (names[i] == null || names[i].length() == 0) then has Empty = true; otherwise, has Empty = false; for (int I = 0; I name.length; i++);

Resumes that can be scanned are: b. Typed on a typewriter.

In order to compile resume data into a database, a resume must be able to be optically searched by a computer reader when it is in hard copy form. When firms scanned paper papers for employment information for recruiting purposes, these forms of resumes became common.

Once an employer obtains your scannable resume, computer software pulls a summary of data needed from it, comprising components like your name, contact information, skills, work history, years of experience, and education.

Before a recruiter or HR professional uses a keyword search to find applicants who meet the specifications of a job posting, scanned resumes and their extracted summaries go to sleep soundly. The technique assigns a ranking to candidates, from the best to the worst. After receiving a wake-up call, the pertinent resumes appear on the recruiting screen, where human eyes take over the hiring process.

Standard fonts and crisp, dark type similar to what a laser printer or typewriter with a new ribbon would generate are used in scannable resumes.

A third-generation programming language (3GL) is now a high-level computer programming language that is more computer as well as programmer-friendly than the first machine code or second-generation assembly languages, with a less specific focus on the fourth and fifth generations. 3GLs are substantially more machine-independent and programmer-friendly than 2GLs.
