WINDOWS NT VERSURSE UNIX NT & LINUX Lin Li COSC 573 Prof. Mort Anvari 2018/9/16

WINDOWSNT & UNIX OVERVIEW * 07/16/96 WINDOWSNT & UNIX OVERVIEW COMMERCIAL OS BUILD ON WINDOWS 3.1 & WINDOWS 95 COMMERCIAL AND NON-COMMERCIAL OS LARGE FAMILY *

FUNCTIONALITY COMMUNICATING WITH MANY DIFFERENT TYPES OF COMPUTERS SECURING SENSITIVE DATA AND KEEPING UNAUTHORIZED USERS OFF THE NETWORK. SO CAN UNIX

FUNCTIONALITY OF MULTI-USER OS LOGGED ON TO THE NT NETWORK, ALL HE/SHE CAN DO IS ACCESS FILES AND PRINTERS NT USER CANNOT RUN ANY APPLICATION ON THE NT SERVER UNIX SERVER: HE/SHE CAN RUN ANY APPLICATION

FUNCTIONALITY OF E-MAIL SERVER HAVE TO BUY A SEPARATE SOFTWARE PACKAGE FREE FOR USE SENDMAIL, EXIM OR QMAIL

FUNCTIONALITY OF INTERNET MANAGMENT DO NOT PROVIDE ANY MECHANISM FOR LIMITING A USER’S DISK USAGE PROVIDE SOFTWARE FOR PERFORMING THIS SEEMINGLY ELEMENTARY CONTROL

FUNCTIONALITY OFSCRIPTING LANGUAGES The likes of a resources for system administration is not found. BOURNE SHELL, KORN SHELL, C SHELL, AND SOMETIMES PERL

ANOTHER ASPECT OF FUNCTINALITY EVEN INSIGNIFICANT CHAGES TO A WINDOWSNT CONFIGURATION REQUIRE OR REQUEST A SHUTDOWN AND REBOOT DO NOT REQUIRE SYSTEM RESTARTS

RELIABILITY LESS CRASHES FREQUENT CRASHES VIRUSES THAT WOULD INCAPACITATE A WINDOWS OS DON’T HAVE AN EFFECT ON UNIX OS FREQUENT CRASHES MEMORY ACCESS VIOLATION AND I/O ERRORS PRONE TO VIRUS ATTACKS ON THE INTEL-BASED HARDWARE

BLUE SCREEN OF DEATH & KERNEL PANIC THERE ARE SO MANY WAYS THAT AN NT SYSTEM CAN CRASH HARDWARE FAILURE HARDWARE UPGRADE KERNEL IS BEING UPGRADED BETA KERNEL IS BEING TESTED

SYSTEM MANAGEMENT GUI require incredible amounts of disk space and memory CDE not require a graphical user interface to function MORE EFFICIENT (KERNELS ARE CUSTON-COMPILED )
