The answer is firewall. It is a network security device that observes inbound and outbound network traffic and chooses whether to allow or block specific traffic based on a well-defined set of security rules. Firewalls have been a first line of protection in network security for over 25 years. The firewall present a barrier between measured and secured internal networks that can be trusted and untrusted outside networks, for example the Internet.

- The INNER JOIN keyword selects records that have matching values in both tables.
- The WHERE clause is used to filter records.
- The WHERE clause is used to extract only those records that fulfill a specified condition.
Answer:
- var today = new Date();
- var dateComp = [];
- dateComp[0] = today.getDate();
- dateComp[1] = today.getMonth();
- dateComp[2] = today.getFullYear();
-
- switch(dateComp[1]){
- case 0:
- console.log("Jan " + dateComp[0] + "," + dateComp[2])
- break;
- case 1:
- console.log("Feb " + dateComp[0] + "," + dateComp[2])
- break;
- case 2:
- console.log("Mar " + dateComp[0] + "," + dateComp[2])
- break;
- case 3:
- console.log("Apr " + dateComp[0] + "," + dateComp[2])
- break;
- case 4:
- console.log("May " + dateComp[0] + "," + dateComp[2])
- break;
- case 5:
- console.log("Jun " + dateComp[0] + "," + dateComp[2])
- break;
- case 6:
- console.log("Jul " + dateComp[0] + "," + dateComp[2])
- break;
- case 7:
- console.log("Aug " + dateComp[0] + "," + dateComp[2])
- break;
- case 8:
- console.log("Sept " + dateComp[0] + "," + dateComp[2])
- break;
- case 9:
- console.log("Oct " + dateComp[0] + "," + dateComp[2])
- break;
- case 10:
- console.log("Nov " + dateComp[0] + "," + dateComp[2])
- break;
- case 11:
- console.log("Dec " + dateComp[0] + "," + dateComp[2])
- break;
- }
Explanation:
The solution code is written in JavaScript.
Firstly, create a Date object (Line 1). The date object will automatically capture the current date and time.
Next create an array dateComp to hold the day, month and year (Line 3 -5). We use the getDate method to get current day, getMonth method for current month and getFullYear method for current year.
This is important to note that the getMonth method will return the value range from 0 - 11 with the Jan is represented as 0, Feb is 1 and so forth. Presume we intend to display the date using the format "month day, year", we can create a switch structure to check the month value which is range from 0 to 11. If month value is 0, generate string Jan + current day + "," + current year. We generate the date string based on different switch cases (7 - 44). We shall see the output similar to the date string as shown below:
Apr 12,2020
