Answer:
false
Explanation:
-exec option is not mandatory for the find command.
find will still list out the identified files even in the absence of -exec option.
For example:
find . -name test -print
will print out files with the name 'test' in the current directory. Note that there is no exec option in this example.
Same holds true for find with no additional options at all.
For example:
find .
will list out all files in the current directory.
Answer:
The answer is "freeze panes command".
Explanation:
To see the row heading information into the columns "X, Y, and Z" we use the freeze panes command, which Pick's the cells from rows and on the right side of the columns, where you scroll.
This tool allows you to block columns/row headings so, the first column /or top row will stay on the screen and you also scroll down or over to see the rest of the panel.
Answer:
From DRAM to DDR4
Explanation:
RAM stands for <em>Random Access Memory.</em> In 1968, Mr. Robert Dennard at IBM's Watson Research obtained the patent for the one-transistor cell that will eventually substitute the old magnetic core memory allocated in computers of the time. By 1969 Intel released the TTL bipolar 64-bit SRAM (Static Random-Access Memory) as well as the ROM "Read Only Memory"; also in 1969 it evolved into "<em>Phase - change memory - PRAM - </em>". However this evolution was not commercialized, Samsung expressed its interest in developing it. In 1970 the first DRAM product was commercially available; it was developed by Intel. In 1971 it was patented EPROM; in 1978 George Perlegos developed EEPROM.
By 1983 a nice breakthrough happened with the invention of SIMM by Wang Labs. In 1993 Samsung came up with KM48SL2000 synchronous DRAM (SDRAM), this variation soon turned into an inductry standard.
In 1996 DDR began a revolution in the memory sector, then in 1999 RDRAM. Both DDR2 SDRAM. DDRR3 and XDR DRAM were commercialized. Finally in 2007 and 2014 the developments of DDR3 and DDR4 were available for the general public.
Answer:
They result in a clear and concise statement of the problem
They ensure that all stakeholder needs are considered.
They result in a document that is easy to understand
Explanation:
Problem statement are very vital in research they are key notes that tells what the research is all about and solution it will provide. They are key notes to understand a research and the knowledge gap the research is filling.
Problem statement is a guide through which solution are measured, it gives a clear direction of what the research is all about.
Problem statement are usually easy to understand, they are written in ways that everyone who picks the paper up can understand why the research was conducted.
All this are why a problem statement is important.
Answer:
Option (4) is the correct answer.
Explanation:
In Java programming language ,array collection starts from 0 index location and ends in a size-1 index location. So to access the last elements the user needs to use a[Size-1] statement. so to modify the value of the last location of the array the user needs to use "a[size-1]= element;".
But when the user wants to add some new value to the end of the array list collection then he needs to use the statement--
a.add(element); //where add is a function, element is a value and a is a array list object.
Another option is invalid because--
- Option 1 is not the correct because "a[3]=element;" modify the value of the 3rd element of the array.
- Option 2 gives a compile-time error because add functions bracts are not closed.
- Option 3 gives the error because a[4] gives the location of the 5th element of the array but the above question says that a is defined with 4 elements.
