Transmission Control Protocol (TCP): TCP is an internet protocol used for exchanging of data between the sender and the receiver. It is a secured protocol for transferring the data. When the sender sends data to the receiver, he/she waits for the acknowledgement from the receiver. If acknowledgement is received then the next data packet will be sent and the process continues till all the data packets are sent. If acknowledgement is not received then the receiver is assumed as hacker or intruder and the connection will be removed. Network Address Translation (NAT): NAT is a method which is used to connect numerous numbers of computers to the internet using a single Internet Protocol (IP) address. It offers the home users who using multiple computers which are used by the family members at home to connect with the internet and small businesses a cheap and efficient internet connections. Usually, most of the companies use more than one router to connect with the internet. But after installing NAT, the mapping is kept only at a single router. Thus, it is essential to use a same router to connect with the internet. Multi-homing with more routers using NAT can be done by using the same router for a single connection and thus mapping is done properly.

Transmission Control Protocol (TCP):

TCP is an internet protocol used for exchanging of data between the sender and the receiver. It is a secured protocol for transferring the data.

write a simple memory management simulator in C that supports paging. In this setup the logical address space (216= 65,536 bytes) is larger than the physical address space (215 bytes), and the page size is 256 bytes. The maximum no. of entries in the TLB (Translation Lookaside Buffer) = 16. memory.c - You are to provide your solution in a single C program named memory.c. Your simulator needs to accomplish the following: 1. Simulate a memory management unit (MMU), which translates logical addresses to physical addresses 1. Translating a logical address to physical address in this setup will involve the following: Check TLB for the page. If page not found in the TLB, check the page table if the page exists in memory. If it does not, then a page fault occurs. 2. Handling page faults involves copy the page from the backing store to memory. Since logical address space is larger than physical address space, a page request might involve replacing a page in memory with the new page. The page…
