Dynamic vs Static Data Structures: Linear Lists Explained
Dynamic vs. Static Data Structures
Dynamic Structures:
Dynamic data structures are structures that grow as a program runs. A dynamic data structure is a collection of items called nodes, normally records. Unlike an array, which contains space for storing a number of elements, dynamic structures are used for the storage of real-world data that are constantly changing. A typical example of a static data structure is the list of passengers on an airline. If this list is kept in alphabetical order in

Track Capacity: Number of sectors per track * Bytes per sector
Cylinder Capacity: Number of tracks per cylinder * Track capacity
Drive Capacity: Number of cylinders * Cylinder capacity
Transfer Time: (Number of bytes transferred / Number of bytes on track) * Rotation time
FAT Size: (Number of blocks * 6) / (Block size + 1)
Magnetic Tape
Density: #bytes/inch (bpi)
S: (Block length + gap) * n (# of blocks)
Block Length: (#bytes / bpi = bytes/inch)
Example Calculations
- 170 sectors/track
- 16 tracks/cylinder

Understanding NTFS Data Blocks, MFT, and File System Areas
Understanding Data Blocks and Their Contents
Data blocks are pointers to the blocks containing the data for an i-node. The first twelve pointers point to the physical blocks containing data described by the i-node, and the last three pointers contain increasing levels of indirection.
Why is Data Fragmentation Less in ext2 Compared to FAT?
ext2 brings together a number of sequential blocks in a group called a block group (BG). FAT, however, places the file where slots are available, regardless of whether

Remote Access
A dial-up network device accepts digital data from a PC and converts it into an analog signal (like a phone signal). These signals are received and converted back to digital format.
Modems
Modems modulate (convert binary to analog) and demodulate (convert analog to binary).
- Internal: Inserted into an expansion slot or integrated into motherboards.
- External: Has its own power supply and connects to a serial port.
Modem Elements
Modems consist of three circuits: a receiving circuit for digital

MATLAB, which stands for “Matrix Laboratory,” is a high-level programming language and interactive environment used primarily for numerical computing, data analysis, algorithm development, and visualization. It offers a range of built-in functions and toolboxes that facilitate mathematical calculations, data manipulation, and graphical representation.
Key Features of MATLAB
- Matrix Operations: MATLAB is designed to work with matrices and arrays, making it particularly powerful for linear algebra and

Converting Binary to Decimal
To convert a binary number to a decimal number, use the following formula: For example, 1101 = 1×2^3 + 1×2^2 + 0x2^1 + 1×2^0 = 8 + 4 + 0 + 1 = 13
Converting Decimal to Binary
To convert a decimal number to a binary number, divide the number and then take the results of the division from bottom to top.
What is a Bit and a Byte?
- Bit: The smallest unit of information that we can store on a computer (0 or 1).
- Byte: A group of 8 bits.
