Basics of computer

Basics of computer and memory


What is machine level language?
➡    It is a low-level language comprised of binary digits(ones and  Zeros).

what is High level language?
➡    Language designed to simplify computer programming. eg, C, C++.

Basic computer architecture


Founder of computer?

Charles Babbage (1791-1871).



First computer in the world

ENIAC (Electronic Numerical Integrator and Computer) was the first electronic programmable computer built in U.S.



➡    Size of data variables depends on the type of compiler.

Types of memory

what is primary memory?
➡     volatile memory. vanishes up when the system is closed or when it is shut down. stores data temporarily.

Secondary memory?
➡    Non volatile. eg, hard disk, SSD. stores data permanently.

Cache memory?
    It is extremely fast memory type.
    It acts as a buffer between RAM and CPU.
    It holds frequently requested data and instructions so that they are immediately available when               needed.
    It is used to reduce the average time to access data from main memory.



As we go from bottom to top cost of memory increases also,
when we move down the above triangle the speed of memory decreases.

Registers ?
It is a temporary storage area built into a CPU.

Example of complexity of water supply in our daily life.

Relation of above example with the computer memory.

hard disk is like the main supply or source of memory. which is accessed through different levels in computer systems.

GTU OOP Program - 17 tic-tac-toe

Image
17). Write a program that displays a tic-tac-toe board. A cell may be X, O, or empty. What to display at each cell is randomly decided. The X and O are images in the files X.gif and O.gif. Note:Due to some reason .gif files were not supporting in my program so instead of .gif images I have used .jpg format images of O and X. import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.image.Image; import javafx.scene.image.ImageView; import javafx.scene.layout.GridPane; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class Program_17 extends Application { @Override public void start(Stage primaryStage) throws Exception { primaryStage.setTitle("Tic-Tac-Toe by kt"); GridPane gridPane = new GridPane(); for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { int n = (int) (Math.random() * 3); if (n == 0) gridP

GTU OS Program - 15 Process creation

15. Write a program for process creation using C. (Use of gcc compiler) Start by creating a new file called process.c using vim Complete code of the program #include <stddef.h> #include <stdlib.h> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> /* Execute the command using this shell program. */ #define SHELL "/bin/sh" int my_system (const char *command) { int status; pid_t pid; pid = fork (); if (pid == 0) { /* This is the child process. Execute the shell command. */ execl (SHELL, SHELL, "-c", command, NULL); _exit (EXIT_FAILURE): } else if (pid < 0 ) //the fork failed. Report failure status = -1; else // this is the parent process. It waits for the child process to complete if (waitpid (pid, &status, 0) != pid)

GTU OS Program - 13 Date Validator

13. Write a shell script to validate the entered date. (eg. Date format is : dd-mm-yyyy). Complete code of the program echo "Date validator" #Initializing values of date, month and year dd=0 mm=0 yy=0 #initializing no of days in a month days=0 read -p "Enter day (dd) : " dd read -p "Enter Month (mm) : " mm read -p "Enter Year (yyyy) : " yy #checking for invalid month if [ $mm -le 0 -o $mm -gt 12 ] then echo "$mm is invalid month. " exit 1 fi #finding out no. of days in a month case $mm in 1 | 3 | 5 | 7 | 8 | 10 | 12) days=31 ;; 2) days=28 ;; 4 | 6 | 9 | 11) days=30 ;; *) days=-1 ;; esac #checking for leap year if [ $mm -eq 2 ] then a=`expr $yy % 4` b=`expr $yy % 100` c=`expr $yy % 400` if [ $a -eq 0 -a $b -ne 0 -o $c
