Exam 1: Introducing Operating Systems

Networking was not always an integral part of operating systems.

____, part of the operating system, is unique to each operating system.

The supercomputer was developed primarily for government applications needing massive and fast number-crunching ability to carry out military operations and weather forecasting.

Operating systems with networking capability have a fifth essential manager called the Network Manager that provides a convenient way for users to share resources while controlling users' access to them.

In a computer, the ____ holds the Central Processing Unit, the Arithmetic and Logic Unit, registers, cache, and main memory.

Second-generation computers were developed to meet the needs of ____.

The type of system designed to perform one specific function is ____.

The Memory Manager is in charge of indirect memory, also known as ROM.

____ systems are used in time-critical environments where reliability is key and data must be processed within a strict time limit.

Vacuum tube computers were used during the period of ____.

The Device Manager monitors every device, channel, and control unit.

If the control unit has two buffers, the second buffer can be loaded while the first buffer is transmitting its contents to or from the CPU.

Many early programs used convoluted logic that only the original programmer could understand, so it was nearly impossible for anyone else to debug or change the program later on.

A supercomputer can perform ____ floating-point operations per second.

Few major advances were made in data management during the 1960s.

Since the mid-1970s rapid advances in computer technology have blurred the distinguishing characteristics of early machines.

The primary distinguishing characteristic of modern computers is ____.

The operating system manages each and every piece of hardware and software.

The ____ allocates each resource, starts its operation, and, finally, deallocates the resource, making it available to the next process or job.

The Memory Manager, the Interface Manager, the User Manager, and the File Manager are the basis of all operating systems.
