8. Without using rm, how can you delete a file? (Hint: How do you rename a file?)

Blocks are the logical records which breaks the area used by a partition; clusters are physical bodies of a hard disk. Hard disk is usually broken in to cylinders and cylinders are broken down in to clusters. Most HDD arrive from the factory with a low level pattern where, block size = 512 bytes. The NTFS file system can produce cluster sizes of a multiple of 512 having a default of 8 blocks for every cluster. Size of a block is multiple of size of cluster, such that a logical block will fit a definite number of physical clusters “one file one cluster”. That is, in every cluster will be installed information belonging at most to a single file. As an aftermath, when scripting a file in a hard disk, some cluster remains incompletely filled or fully unused. As the operating system can only write an entire block, it pursues that the idle space should be fit with some strings of bytes that can be used by others. It should be remembered that these data are saved in a disk because of the operating system curbs to write only on an entire block, they could be detected by locating

This directory is used to store the files for the root or super users documents

32,767 Unicode characters with each path component (directory or filename) commonly up to 255 characters long

5) What is the digit span? what does this indicate about the capacity of STM?

Increase your computer's storage capacity with the Seagate ST1000LM024 hard drive. Store the entire family's favorite photo library, large multimedia files, and MP3 music files with more than enough space leftover. Hobbyists and professionals alike appreciate the dependability and design of the STBD1000100 as well as the massive 1TB storage capacity it offers. The internal 2.5-inch hard drive is easy to install and is compatible with machines that support SATA II and SATA I interfaces. With rugged construction, you can enjoy sustained performance without worry of component malfunctions or mechanical breakdowns. You will never have to worry about installing the casing either.

The first phase of analyzing a hard disk is locating the partition tables and their data structures. In the second phase, these partitions are processed in order to identify their layout and how they are merged. Third, the layout information is extracted and fed into a data analysis tool or a file system that maps the offset of the partition. Alternatively, this information can be printed to help the user

0-255. Answer D is incorrect because the ExtendedUnique Identifier is another addressing scheme used by iSCSI, which is

Similarly, if the old block is 8 bytes and the new block is 4 bytes, then the contents of the new block are identical to the first 4 bytes of the old block. These semantics match the the semantics of the corresponding libc malloc, realloc, and free routines. Type man malloc to the shell for complete documentation.

c) When support for the tools and language used to develop the software is unavailable. This is a particular problem with early 4GLs where, in many cases, the vendors are no longer in business.

Seven bytes are allocated in a DATE column to store the century, year, month, day, hour, minute, and second of a date. _________________________

The NTFS file system contains a file called the master file table, or MFT. There is at least one entry in the MFT for every file on an NTFS volume, including the MFT itself. All information

c) Do PSDN frames have destination addresses or virtual circuit numbers in their headers? [394]

A(n) ________ is a dedicated high-speed network consisting of both hardware and software, used to connect and manage shared storage devices.

But does this mean that digital storage units such as the Kilobyte can be either 1000 or 1024 Bytes? Well... no. Engineers use Kilobytes, Megabytes, Gigabytes, etc, to make life easier. The computer uses Kibibytes, Mebibytes, Gibibytes, etc. The "bi" prefix is the binary version of our normal metric values.
