Regarding your own computer in front of you, can you look up information on what hardware components you have? List CPU, memory, storage, networking details as reported by your operating system (windows, macosx, linux, ...)

How did you look the information up? What do they say?

Discuss details on each: cpu, memory, storage, network...

How do these things matter when selecting a type of virtual machine in cloud compute services?

General Compute questions

Describe what is big endian vs little endian

Examples of CPUs that are big endian: SPARC, MIPS, 68k, DEC Alpha, PA-RISC, IA-64, SuperH

How can you tell whether a computer is big endian or not programmatically?

#include <stdio.h> 

/* function to show bytes in memory, from location start to start+n*/
void show_mem_rep(char *start, int n) 
{ 
	int i; 
	for (i = 0; i < n; i++) 
		printf(" %.2x", start[i]); 
	printf("\n"); 
} 

/*Main function to call above function for 0x01234567*/
int main() 
{ 
        int i = 0x01234567; 
        show_mem_rep((char *)&i, sizeof(i)); 
        //getchar(); 
        return 0; 
}

If this prints 67 45 23 01 then little endian. If you get 01 23 45 67 then big endian.

Why does the endianness matter?

What happens when you write a binary file on big endian machine and read it back in little endian machine?

what happens when you write non-binary data, e.g. ASCII, or UTF-8 data, into the files and read them back on different endian machines, does it matter much?

What needs to be done for binary data in the IP header read from network?

What Technique Is Used To Measure The Number Of Copies Of A Gene Or An Rna Molecule In Human Tissues?

Answer :

PCR or polymerase chain reaction in real time, as opposed to the conventional method, because the number of copies of the target molecule can be monitored for each PCR cycle.

How Much Template Do You Need For Sequencing?

Answer :

For PCR product size of product(bp)/50 = ng DNA. For plasmid up to 10.0 kb 250-300 ng. For genomic DNA 2.0 microgram.
