Study Notes
File Systems
- FAT (File Allocation Table) file system structure consists of a boot sector, FAT, and data sectors.
- FAT boot sector contains essential information about the file system, including the location of the FAT and data sectors.
- Windows and Unix volumes use different file system structures, with Windows using FAT and NTFS, and Unix using its own file system structure.
Partitions and Volumes
- Partition Sector Zero contains information about the partition, including the file system type and boot sector location.
- FAT16 is a type of file system that uses a 16-bit file allocation table.
- Volumes and partitions are terms used to describe logical divisions of a disk.
- Windows and Unix use different partitioning schemes, with Windows using a master boot record (MBR) and Unix using a disk label.
Directory Structures
- A directory is a hierarchical structure that organizes files on a disk.
- The root directory is the top-most directory in a file system.
- A parent directory is a directory that contains subdirectories.
- An absolute path name is a path that starts from the root directory, while a relative path name is a path that starts from the current directory.
Disk Formatting
- Disk formatting involves dividing a disk into logical sectors and assigning file system structures.
- The disk formatting process creates a partition table, boot sector, and file system structures.
Endianness
- Endianness refers to the byte order used to store multi-byte data.
- Big Endian stores the most significant byte first, while Little Endian stores the least significant byte first.
- Understanding the endianness used by a computer is essential to read the information stored in it.
Network Topologies
- Network topologies describe the physical and logical arrangement of computers in a network.
- Physical topologies define the actual layout of the wire (media), while logical topologies define how the media is accessed by the hosts.
- Network components include Network Interface Cards (NICs), Unshielded Twisted Pair (UTP) cables, and Shielded Twisted Pair (STP) cables.
Network Components
- A network consists of computers connected to each other using wired or wireless connections.
- Wired connections use cables, while wireless connections use WIFI, 4G, or 5G.
- Network Interface Cards (NICs) are used to connect computers to a network.
