 +====March, 2016====
 +Currently in March, we have playing more with primes and utilizing primefork, primethread, and currently we are playing with different types of network interfaces.
 +
 +PrimeFork.c
 +
 +Contain(s) 
 +Primebrutefork.c
 +Primesqrtfork.c
 +
 +Primebrute utilizes our brute force method of accessing each individual number from 2 to the max number specified for that range.
 +
 +Primesqrt utilizes our square root approach and lowers the number it has to search for in order to determine if it's prime.
 +
 +The fork uses a process of quite literally multiplying the program itself but then the program has a check statement to make sure that the program multiplied is either the true parent or a child/forked process.
 +
 +
 +
 +PrimeThread
 +Contain(s)
 +Primebrutethread.c
 +Primesqrtthread.c
 +
 +Primebrutethread again uses the brute force method but instead of multiplying the process and causing a ton of memory over head, instead we actually just enact a small void statement that loops until it's finished.
 +
 +Like our friend fork, the thread divides up the number by using the threads given to it but like I said, it doesn't multiply the program. Instead of cloning the program, it runs a small statement that the pthread asks for.
 +
 +Basically Thread -> void statement to run.
 +
 +The Primebrutethread does our traditional brute force method but with divided numbers and smaller memory allocation.
 +
 +Primesqrthread.c does the same thing as the Primesqrtfork.c but with less memory overhead.
 +
 +
 +Sockets
 +Next we have been playing with sockets and created two network like programs.
 +
 +The first is timeserv.c that when you use your client/telnet into the timeserv port that's reserved, it will tell you the time and disconnect you from the server.
 +
 +The second is ipaddr which returns to the user different network interfaces and the ip associated with them.
