Software

ltll s$stems are configured in DUltL BAA mode ie Students can boot fromindows 4 or Linu as per their lab reuirement

his is er$ useful for students because the$ are familiar with differentAperating S$stems so that the$ can eecute their programs in different programming enironments

8ach student has a separate login for database access

Aracle 5i client ersion is installed in all s$stems An the serer account for eachstudent has been created

his is er$ useful because students can sae their wor- scenarios plCsl programs data related pro6ects etc in their own accounts 8ach studentwor- is safe and secure from other students

Latest echnologies li-e DA 98 and 288 are installed in somes$stems Before submitting their final pro6ect the$ can start doing mini pro6ect from 2nd $ear onwards

ltS acro ltssembler is installed in all the s$stems

Students can eecute their assembl$ language programs using ltS

ltS is er$ useful students because when the$ eecute their programsthe$ can see contents of 4rocessor egisters and how each instruction is being eecuted in the (4U

ational ose Software is installed in some s$stems

Using this software students can depict UL diagrams of their pro6ects

Guidelines to Students

o to 4un Sell Scri+ts

here are two wa$s $ou can eecute $our shell scripts Ance $ou hae created a scriptfile

ethod 14ass the file as an argument to the shell that $ou want to interpret $our script

Step 1 create the script using i e or ed

or eample the script file show has the following lines

echo ere is the date and timedate

Step 2 o run the script pass the filename as an argument to the sh shell

G sh show

ere is the date and timeSat 6un 73 1371) 4S 277+

ethod 2a-e $our script eecutable using the chmod command

hen we create a file b$ default it is created with read and write permission turned onand eecute permission turned off lt file can be made eecutable using chmod




Step 2 a-e the file eecutable

G chmod uE scriptHfileG chmod uE show

Step 3 o run the script 6ust t$pe the filename

G showere is the date and timeSat 6un 73 1371) 4S 277+

o to run C +rogras

Step 1 Use an editor such as i e or ed to write the program he name of the file

containing the program should end in c

or eample the file showc contains the following lines

mainI

printfJ welcome to gt98( JK

Step 2 Submit the file to (( the ( (ompiler

G cc showc

ampf the program is o-a$ the compiled ersion is placed in a file called aout

Step 3 o run the program t$pe aout
