The answer is (c.) a DDR SDRAM module.
DDR SDRAM stands for Double data rate synchronous dynamic random-access memory. It is a form of temporary data storage in a computer. So when it comes to power down, the data stored in this RAM is most likely to lose.
<span>Random access memory.
This problem requires you to know what the different types of memory are and their relative advantages and disadvantages. Let's look at them and see why 3 are wrong and one is correct.
read-only memory: Otherwise known as ROM, this type of memory stores code that can't be over written. Used frequently for constant lookup values and boot code. Since it can't be written to by normal programs, it can't hold temporary values for Samantha. So this is the wrong choice.
random-access memory: Otherwise known as RAM, this type of memory is used to store temporary values and program code. It is quite fast to access and most the immediately required variables and program code is stored here. It can both be written to and read from. This is the correct answer.
hard disk: This is permanent long term readable and writable memory. It will retain its contents even while powered off. But accessing it is slow. Where the contents of RAM can be accessed in nanoseconds, hard disk takes milliseconds to seconds to access (millions to billions of times slower than RAM). Because it's slow, this is not the correct answer. But it's likely that Samantha will save her spreadsheet to hard disk when she's finished working with it so she can retrieve the spreadsheet later to work on again.
compact disk: This is sort of the ROM equivalent to the hard disk. The data stored on a compact disk can not be over written. One way of describing the storage on a compact disk is "Write Once, Read many times". In most cases it's even slower than the hard disk. But can be useful for archiving information or making backups of the data on your computer.</span>
Answer:
A, C, D and E
Explanation:
An intranet is synonymous to a private LAN or WAN network but in contrast to the extranet or internet. Resources are retrieved and/ or shared within devices in the private network. It uses the internet protocol suite model of networking for communication, but also uses private IP addresses, which are not routable on the internet.
The communication between devices can be a peer to peer connection or client-server connection, using the mainframe computer technologies as the dedicated servers of the network.
Answer:
C) someThing.someMethod( )
Explanation:
The methods in a class can be accessed outside the class (assuming they are public methods and not private to the class) by using the dot(.) symbol and calling the method on the instance or object of the class.
In this case, the object of the class someThing, calls the method, someMethod( ) by using a dot and the name of the method with a parentheses at the end. This enables the code in the method act on the class instance or object.
Answer: print(f'$5,242.83')
Explanation: print(f'$5,242.83')
