write a program that creates two children, and connects the standard output of one to the standard input of the other, using the pipe() system call.
A pipe is a unidirectional data channel that can be used for inter process communication and is created by the pipe() function.
Explain about the pipe system call?An invocation of pipe() causes control to trap to the kernel, establish the pipe's storage, and then return with two pointer call descriptors of type "int". The pipe() call's return value for the pointers is an array parameter. Additionally, it returns a negative integer if the call was unsuccessful and zero if it was successful.
The pipe function creates a pipe and inserts the reading and writing endpoints of the pipe's file descriptors into filedes [0] and [1, respectively]. File descriptor 0 represents standard input, while file descriptor 1 represents standard output, making it simple to remember that the input end comes first.

what is the size of the bit vector of a 1tb disk with 512-byte blocks? a. 2 mb b. 28 mb c. 28 mb d. 8 mb
Option C. Bit vectors are one-dimensional, zero-originated arrays of booleans. They are shown as a series of 0s and 1s separated by the symbol #*, for example, (make-bitvector 8 #f) #*00000000.
Bit vectors can be used with array methods because they are a special instance of one-dimensional bit arrays; for more information, see Arrays. In essence, a bit vector is a vectorbool> because it is a Sequence with the same interface as a vector. The primary distinction is that bit vector is space-efficiently optimized. A bit vector just needs one bit per element but a vector always needs at least one byte.
The translation of memory size into 2 powers is crucial for OS numericals.
Disk size = 1TB = 240 B, then.
Block Size: 4 KB, or 2 12 B
Block count is equal to (240) / (212) = 228 blocks.
Now that we need 1 bit to represent each block in a bit map, the size of the bitmap in bits is 228 bits (to represent 228 blocks).
Bitmap size in Bytes is therefore 228 / 23 = 28 MB
