TRUE/FALSE

1.The operating system manages each and every piece of hardware and software. T
2.An operating system is a special type of hardware.
F
3.The Memory Manager, the Interface Manager, the User Manager, and the File Manager are the basis of all operating systems. T
4.Networking was not always an integral part of operating systems. T
5.The Memory Manager is in charge of main memory, also known as ROM. F
6.The high-level portion of the Process Manager is called the Process Scheduler. F
7.The Device Manager monitors every device, channel, and control unit. T
8.The File Manager is responsible for data files but not program files. F
9.When the Processor Manager receives a command, it determines whether the program must be retrieved from storage or is already in memory, and then notifies the appropriate manager. T
10.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. T

11.The central processing unit (CPU) is the brains of the computer with the circuitry to control the interpretation and execution of instructions. T
12.Until the mid-1970s, all computers were classified by price alone. F
13.The supercomputer was developed primarily for government applications needing massive and fast number-crunching ability to carry out military operations and weather forecasting. T
14.The minicomputer of the 1970s was smaller than the microcomputer. F
15.Since the mid-1970s rapid advances in computer technology have blurred the distinguishing characteristics of early machines. T
16.The Intel 4004 chip in 1971 had 2,300 transistors while the Pentium II chip twenty years later had 7.5 million, and the Pentium 4 Extreme Edition processor introduced in 2004 had 178 billion transistors. T

17.Card systems date from the earliest computers, which relied on punched cards or tape for input when a job was entered by assembling the cards into a deck and running the entire deck of cards through a card reader as a group. F

18.Real-time systems are used in time-critical environments where reliability is key and data must be processed within a strict time limit. T
19.Onboard systems are computers placed inside other products to add features and capabilities. F
20.The first bug was a moth trapped in a Harvard computer. T
21.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. T
22.In the 1950s, only one FORTRAN program could run at a time, and then the FORTRAN compiler had to be reloaded into memory. F
23.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. T
24.Few major advances were made in data management during the 1960s. T
25.A process requires space in main memory where it resides during its execution although, from time to time, it requires other resources such as data files or I/O devices.
T
