b78
C.88
Cao 90
Correct answer: C.
2). Of the following statements about orbit, the correct one is ().
A. The tracks on the disk surface are a set of concentric circles.
B. Because the circumference of each track is different, the storage capacity of each track is also different.
The track on the surface of the disk is archimedean spiral.
D The number of tracks in the innermost circle is 0, which gradually increases from inside to outside, and the number of tracks in the outermost circle is the largest.
Correct answer: a
Answer analysis: the two sides of the disk are divided into 80 concentric circles, each concentric circle is called a track, and the track number is: the outermost track is 0, and the innermost track is 79. Each track is divided into 18 equal-length segments, also called sectors, and each sector can record 5 12 bytes. All information on the disk is read and written by sectors.
3). The earliest application field is

Correct answer: C.
Computer memory can be divided into two categories: internal memory and external memory. Memory is an integral part of the computer host, which directly exchanges information with CPU, and is mainly used to store data and programs.
6). The operating system divides the CPU's time resources into extremely short time slices, which are distributed to the end users in turn, so that the end users can share the CPU's time slices alone and make them feel monopolized by the computer. This operating system is called ().
A. real-time operating system
B. Batch operating system
C. Time-sharing operating system
D. Distributed operating system
Correct answer: C.
Time-sharing operating system: different users use a computer interactively through their respective terminals, and the computer uses? Timeshare? * * * * Streams serve every user. The main characteristics of time-sharing system are: the simultaneity of multiple users using computers at the same time, the interactivity of man-machine question and answer, the exclusiveness of each user using computers independently, and the timeliness of system response.
