The database system allows the creation of a single depository of information, which is updated periodically and which can be used simultaneously by many users, since this type of system allows the effective sharing of all data stored in its depository . In addition, this is a secure system and is very difficult to break into. This is because of the efficiency of the software used to maintain it. However, the use of these softwares can be a little complicated for users, in addition to requiring a high economic cost to obtain them.
The traditional file system, in turn, each user must obtain their own file related to the application they want to run. This may seem dull in comparison to the database, but it is advantageous as it does not require any spending on software, as it is simple and there are several cheap and efficient tools and editors on the market. However, this system is not so safe, it can cause isolation of data and even data inconsistency, which disrupts the entire system.
Answer:
if(soldYesterday > soldToday){
salesTrend = -1;
} else if(soldToday > soldYesterday){
salesTrend = 1;
}
Explanation:
The if/else statement is more explicit. The first if condition check if soldYesterday is greater than soldToday, if true, then -1 is assigned to salesTrend.
Else if soldToday is greater than soldYesterday, if true, then 1 is assigned to salesTrend.
Answer:
a) Time to live field
b) Destination
c) Yes, they have two ip addresses.
d) 128 bits
e) 32 hexadecimal digits
Explanation:
a) the time to live field (TTL) indicates how long a packet can survive in a network and whether the packet should be discarded. The TTL is filled to limit the number of packets passing through N routers.
b) When a large datagram is fragmented into multiple smaller datagrams, they are reassembled at the destination into a single large datagram before beung passed to the next layer.
c) Yes, each router has a unique IP address that can be used to identify it. Each router has two IP addresses, each assigned to the wide area network interface and the local area network interface.
d) IPv6 addresses are represented by eight our characters hexadecimal numbers. Each hexadecimal number have 16 bits making a total of 128 bits (8 × 16)
e) IPv6 address has 32 hexadecimal digits with 4 bits/hex digit
The correct answer is A. Only technician B is correct because I don't believe carbon is form of resistors.
