Embedded Software Development

Using specific programming languages (like C and C++) to write code for a specific hardware device in which it runs is called embedded software development. It makes the device smart by performing actions based on user's input which improves the user experience. They are designed to perform function-specific tasks rather than doing multiple tasks like computers. The embedded system is incredibly intuitive. An embedded software system could be a system developed and organized on any device, apart from an old-fashioned computer. It is the brain of a specific device; however, it is a solely useless tool and simple to elucidate what software system is embedded.

Page There is a famous railway station in PopPush City. Country there is incredibly hilly. The station was built in last century. Unfortunately, funds wwere extremely limited that time. It was possible to establish only a surface track. Moreover, it turned out that the station could be only a dead-end one (see picture) and due to lack of available space it could have only one track. 5, 4, 3, 2, 1 1, 2, 3, 4, 5 Station The local tradition is that every train arriving from the direction A continues in the direction B with coaches reorganized in some way. • Assume that the train arriving from the direction A has NS 1000 coaches numbered in increasing order 1, 2, .

Q4:- A fast computer is used to break a ciphertext (A) using columnar transposition cipher that needs 150 attempts, the speed of processor is 4 MIPS (million instructions per second), and each attempt needs 5 instructions. Another computer of speed 3 MIPS is used to break ciphertext (B) using Caesar Cipher that needs 110 attempts, and each attempt needs 4 instructions for ciphertext (B). Determine which ciphertext will be broken first (consider the worst case, i.e. the last attempt is the successful one), write your answer in details?
