Chapter 4 Power Point Answers and Questions
1.
Describe system software. Discuss each of the four types of system programs.
“System Software,” automatically runs, handling technical details with the use of operating systems of;
utilities, device drivers, operating systems, and language translators. The “utilities” are specializeprograms that make computing easier; like antivirus programs use to clean/protect the user’s computer,
or backup programs in case the user’s computer crash and data is lost. “Device drivers” allow
communication between computer and device, but in the computer tower, they also have internal
storage devise. An “Operating system” is use to help open and maintain multiple programs, so for
example: a user can open an application and antivirus program, let the virus sweep and check for virus
while using the application. Last, “language translators” is a software that can automatically translate
one language a user can’t read, to one that they can read.
2.
Define operating systems. Describe the basic features and the three categories of operating
systems.

manage the computer’s resources, like coordinating with the monitor, printers, storage, memory, and
processing. The three categories of the operating system are: “Network operating systems” (linked
computers), like Windows Servers which coordinates and communication between networks servers;
“Embedded operating systems” (handheld), like smartphones, cable, or portable video game systems;
and “Stand-alone operating systems” (desktop) which is also known as “client operating system.”
3.

and “OS X Mavericks” which improves the power management. The “UNIX” operating system runs on
personal and mainframe computers. It’s now use to support the web environment. The “LINUX” is
similar to the UNIX operating system but is use as an extension system for it. Last the Chrome OS is
similar to LINUX and UNIX but as is own operating system that focuses on the internet connectivity and
cloud computing.
Virtualization supports multiple operating systems that operates independently on a single machine.
The two type are “Host operating systems” and “guest operating systems.” Lastly “Hyper-V” is the
newest virtualization on Windows 8.
5.
Discuss utilities. What are the most essential utilities? What is a utility suite?
Utilities are specialize-programs to make computing easier. There are four essential utilities:

programs. Utilities suites are a group of utility programs in one package. The benefit for that is that they
are less expensive than sold separate. Some known utilities suites are, Norton Utilities and Bit Defender.

When a user install a new device, the Add a Device Wizard is use to step-by-step installation. When new
