Answer:
Maintenance Phase
Explanation:
One of the concepts employed in project management for describing stages involved when carrying out an information system development project is the systems development life cycle (SLDC). The cycle which starts from carrying out a feasibility study and ends in maintenance is a highly used conceptual model. There are 5 major stages or phase and they are the; Requirement Phase, Design Phase; Implementation Phase, Test Phase, and the Maintenance phase. The maintenance phase comes when testing has been complete and all enhancement and modifications have already been developed, and the system is operating.
Answer:
d. ICMP Echo Reply (type 0)
Explanation:
ICMP or internet control message protocol is an Internet layer protocol in the TCP/IP suite. It works together with routing devices like the router to send messages based on results sensed in the network.
The RFC 1122 has stated that the ICMP server and end user application be configured or installed in user devices, for receiving and sending ICMP echo request packets and reply. The process is called pinging.
For an attacker to implement ping of ping, he needs to confirm if the target user in live by sending an ICMP echo request packet type 8, to receive an ICMP echo reply type0.
The loop terminates when "xxxxx" is read in. If the word is land, the string followed by "land" get outputted. The same with air, and water.
Explanation:
int land = 0;
int air = 0;
int water = 0;
String word = "";
while(!(word.equals("xxxxx"))) {
word = stdin.next();
if(word.equals("land")) {
land++;
}else if(word.equals("air")) {
air++;
}else if(word.equals("water")) {
water++;
}
}
System.out.println("land:" + land);
System.out.println("air:" + air);
System.out.println("water:" + water);
