Consider a file system using the indexed allocation. The block size is 512 bytes and the pointer to a block takes 2 bytes. The largest file size that a one level indexed allocation method could handle is ___________ KB. Recall that 1KB is equal to 210 bytes. Answer -1 if there is no limit based on the provided information.
Answer:
128 KB
Explanation:
Given data :
The block size = 512 bytes
Block pointer size = 2 bytes
In an indexed allocation, a special block named Index Block contains all the pointers to the blocks that the file had occupied.
Therefore, the maximum number of block pointer in 1 block :
[tex]$=\frac{\text{block size}}{\text{pointer size}}$[/tex]
[tex]$=\frac{512}{2}$[/tex]
= 256
Thus, a block can hold maximum 256 pointers.
It is given the level of indexing is one. So,
Maximum size of the file = maximum number of block pointers in 1 file x block size
= 256 x 512
[tex]$=2^8 \times 2^9$[/tex]
[tex]$=2^{8+9}$[/tex]
[tex]$=2^{17}$[/tex]
[tex]$=2^7 \times 2^{10}$[/tex]
[tex]$=128 \times 2^{10}$[/tex]
= 128 KB (∵ 1 KB = [tex]2^{10} \ B[/tex] )
Therefore, the largest file that 1 level if indexed allocation method can handle is 128 KB.
five technology tools and their uses
Answer:
Electronic boards
Videoconferencing ability
Search engines
Cloud services
Computing softwares
Explanation:
Technology tools are used to simplify task bring ease, comfort as well as better satisfaction :
The use of electronic boards for teaching is an essential tool for students and educators alike as it provides great features aloowibg teachers to write and make drawings without hassle. This clear visual display goes a long way to aide student's understanding.
Videoconferencing breaks the barrier that distance and having to travel bring swhen it comes to learning. With this tools, students and educators can now organize classes without having to be physically present un the same class room.
Search engines : the means of finding solutions and hints to challenging and questions is key. With search engines, thousands of resources can now be assessed to help solve problems.
Cloud services : this provud s a store for keeping essential information for a very long time. Most interestingly. These documents and files can be assessed anywhere, at anytime using the computer.
Computing softwares : it often seems tune consuming and inefficient solving certain numerical problems, technology now p ovide software to handles this calculation and provides solutions in no time using embedded dded to codes which only require inputs.
