Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

An-Najah National University Department of Computer Engineering Microprocessors (10636322) Assignment # 1 Answer the following: 1- Write an 8086-assembly program that reads only vowels (a, e, i, o, u) from the keyboard (other characters are not excepted) and store them in a character array of 10 bytes long. Vowels entered after the array is full should be discarded. The program should stop reading characters when a 'S' is entered. When the 'S' character is entered, the program should output a new line, followed by the contents of the character array, with a space character between each vowel. 2- Write an assembly code to sort a word array of 50 numbers in ascending order. 3- The perfect number is defined as an integer which is equal to the sum of its divisors.

branch instructions -> machine language translationThe following programme gives an example of how to calculate the branch offsets in a programme once the process for computing the branch offsets for the branch instructions has been described. Because the final two bits of the address will be dropped in this case, the branch offsets may be calculated by simply adding or subtracting line numbers. In contrast to "the $pc contains the address of line," which would be erroneous, the text will thus read "the $pc points to line," which is accurate.
Topic: MARIE Assembly Language (Simulator) Identification: Using MARIE Assembly Simulator, identify the following: What is the address of the last (bottom-rightmost) memory location? How many bits does an address have? How many bits are the contents of one memory address? What is the content of memory address 001? (No need to write 0x from hereon; we already assume hexadecimal unless otherwise stated.) The memory address 000 contains an instruction. What is the hexadecimal digit corresponding to the opcode of that instruction?
