Solution
Operating system:
as well to the hardware, a computer also requires a program to control the devices. This program
is named an operating system
An OS is system software that administers computer hardware and software sources and
provides frequent services for computer programs. every computer programs, without firmware,
need an operating system to function.
Interface:
an interface is a communal boundary across which two individual components of a computer
system exchange information. The exchange can among software, computer hardware, peripheral
devices, humans and combinations of these.
operating systems types are Windows, Linux and Mac OS
operating systems different versions are Windows 7, 8 and 10
operating systems user interfaces are text user interfaces (TUI) and graphical user interfaces
(GUI).

Cache Consistency – Requirements and its packet processing Performance implic...Michelle Holley
The audio starts at 9:00 due to a glitch while recording.
The topic can be as well stated as “All Processor Accesses are not created equally” – H/W and S/W Synergy – Methods and Mechanism:
- The developers in the audience, throughout the class, will wear different hats – first as a hard design engineer and look at platform design choices.
- Then they will wear the hat of driver developer and see the requirements and assumptions of driver on the hardware behavior.
- Then they will wear the hat of system architect and venture out to find out choices as how s/w and h/w can be in synergy and communicate – thereby potential optimum implementation can be made.
