Binary Units
Binary units are used to measure digital data storage. The smallest unit is a bit which can have a value of 1 or 0. 8 bits make up a byte. 1024 bytes make up a kilobyte. Common units include kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes and zettabytes with each unit being 1024 times larger than the previous. Converting between units involves multiplication when going to smaller units and division when going to larger units.

This document describes an experiment to determine how much computer memory is needed to store different lengths of text. The experiment involves writing text files with varying numbers of letters or words and comparing the file sizes. Based on initial tests, the student found that the number of words in a file and the file size were almost the same and had a proportional relationship, with more words leading to larger file sizes.
SD & D Negative Numbers
The document discusses different methods for representing negative numbers in binary, including signed bit representation and two's complement representation. It explains that two's complement is better because it provides symmetry around zero and preserves the rules of addition. Two's complement works by flipping all the bits and adding one to get the opposite value. The document also discusses the range of numbers that can be stored in one and two bytes using two's complement representation.
SD & D Representing Positive Numbers
This document provides information about decimal and binary number systems. It discusses how decimal numbers like 42678 represent quantities in terms of places values of tens, hundreds, thousands, etc. It then introduces the binary number system which uses only two digits, 0 and 1, to represent numbers in computers. The key advantages of the binary system for computers are its simplicity with only two states, good noise tolerance, simple calculations, and suitability for magnetic and optical storage media which also use two states. The document explains how to convert between decimal and binary numbers by representing them as place values and using addition and subtraction.
SD & D Maintenance
Maintenance involves making changes to software after it has been delivered to the client. There are three categories of maintenance: corrective, adaptive, and perfective. Corrective maintenance fixes bugs, adaptive maintenance makes changes due to environment changes like new hardware or software, and perfective maintenance adds new features or functionality. Factors like insufficient documentation, too many versions, staff mobility, and external changes can negatively impact maintenance. Maintenance is a significant cost, estimated to be between 40-70% of total software development costs.
Virtual machines, emulators and mobile devices
A virtual machine is a software-based computer that runs an operating system and applications. A hypervisor program manages and allocates resources like the CPU and memory to each virtual machine, allowing multiple operating systems to run simultaneously on one physical machine. Virtual machines provide advantages like running different operating systems at once and easier maintenance, but may lead to unstable performance when running simultaneously due to inefficiencies accessing hardware.
SD & D Representing Text
Characters are represented using character sets that assign a unique binary code to each character. The ASCII character set uses 7 bits to represent 128 characters, while Extended ASCII uses 8 bits to represent 256 characters. Unicode uses 16 bits to represent up to 65,536 characters to support international languages. Error detection methods like parity bits are used to detect errors during data transmission by checking if the number of 1 bits is even or odd as expected.
SD & D Real Numbers
Real numbers include integers, rational numbers like fractions, and irrational numbers like pi. They can be positive, negative, or zero. In computing, real numbers are represented using floating point notation, where the number is stored as a mantissa and exponent. The mantissa holds the significant digits of the number, while the exponent tracks the decimal place. Increasing the bit sizes of the mantissa and exponent allows for greater accuracy or range of real numbers that can be represented, respectively.

Testing SQL
The document provides examples of testing SQL queries by comparing the actual results of a query to expected results. It shows sample data from car rental and car databases, expected outputs for queries on the data, and the correct SQL queries to produce the expected outputs. For the first example, the correct query includes a JOIN and column aliases. For the second example, the correct query uses MAX instead of COUNT, includes a GROUP BY, and uses an alias for the column heading.
SQL
The document provides examples of SQL queries on a car hire database with four tables: Customer, Booking, Car, and Depot. It demonstrates the use of wildcards, aggregation functions like COUNT, SUM, AVG, and MIN/MAX. It also shows how to use GROUP BY, ORDER BY, computed values, aliases, and subqueries to retrieve specific data from the tables.
Database Query Design
This document provides 12 examples of SQL queries that could be written for a car hire database consisting of 4 tables: Customer, Booking, Car, and Depot. Each example includes the fields and calculations, tables, search criteria, grouping, and sort order that would be used to write the query. The examples cover a range of different queries including finding specific car details, aggregating data, joining multiple tables, and using minimum, maximum and average functions.
Data Dictionary
A data dictionary contains information about the data items in a database, including the entity or table name, attribute or field name, data type, size, whether it is required, and any validation rules. For example, a school data dictionary would specify that the Class table has attributes like ClassID which is the primary key, Classroom which is a number that must be between 1 and 10, and MainBuilding which is a yes/no field. It also describes pupil attributes like CandidateNum which is the primary key consisting of 7 numeric characters and ClassID which is a foreign key that must match an existing ClassID.
Compound Keys
Primary keys uniquely identify records in a table. Foreign keys link tables by providing a link to a related table. A compound key uses two or more attributes to uniquely identify records when no single attribute can be used as the primary key, such as in a table recording bike rentals where a member can rent multiple bikes and bikes can be rented by multiple members, so the compound key uses the member ID, bike ID, and rental date.
Entity Occurrence Diagrams
The document discusses entity occurrence diagrams and how they are used to determine the cardinality between entities. It provides examples of a car hire entity occurrence diagram and a capital cities entity occurrence diagram. The car hire diagram shows a one-to-many relationship between bookings and customers, as one customer can have multiple bookings but each booking is for only one customer. The capital cities diagram shows a one-to-one relationship between countries and their capital cities, as each country has one capital city and each capital city is only associated with one country.
Entity Relationship Diagrams
An entity relationship diagram (ERD) graphically represents the entities in a database and their relationships, showing entity names, relationships, cardinality, and optional attributes. Cardinality describes the numerical relationship between rows in related tables as one-to-one, one-to-many, or many-to-many. Examples show the ERD for employees and companies, and customers, bookings, cars, and depots.
Database Analysis
This document outlines the end user and functional requirements for a doctor's surgery database. The end user requirements include searching appointments, patient medical histories, personal details, patients by medication or age range, and calculating average patient ratings by doctor. The functional requirements specify tables for doctors, patients, appointments with relevant fields, as well as database processes like queries, averages, sorts, and counts.
Software Evaluation
The document discusses different aspects of evaluating software solutions including ensuring they are fit for purpose, use efficient coding constructs, are usable, maintainable, and robust. Fitness for purpose is evaluated by testing functional requirements. Efficient coding uses appropriate constructs like arrays, loops, and nested statements. Usability considers how easily users can achieve goals. Maintainable code is modular and readable. Robust programs handle errors and unexpected inputs gracefully.
Software Testing
Software testing is done for several reasons: to identify errors, ensure the program matches its specifications and requirements, and check efficient performance. Test data includes normal, extreme, and exceptional cases. A test table is produced to test a student test score program with sample normal, extreme, and exceptional input data. Different types of errors include syntax errors, execution errors that cause crashes, and logic errors that produce unexpected results. Techniques for testing include dry runs, trace tables, breakpoints to stop at lines, and watchpoints mapped to variables to stop when values change.
Standard Algorithms
This document discusses several standard algorithms:
1) Linear search searches an array to find a value and returns its position or a message if not found.
2) An improved linear search algorithm stops searching once the item is found and returns a message if not found.
3) Count occurrences counts how many times a value appears in an array.
4) Finding the maximum/minimum value in an array uses comparisons to update the running maximum/minimum value found.
File Handling
The document discusses file handling in Python. It describes text files and CSV files, how to read from and write to these file types in Python. It provides pseudocode and Python code examples to open, read, and write data from text and CSV files, then close the files. The key steps are to open the file, read or write data, then close the file.
Python Predefined Functions
This document provides an overview of several predefined Python functions including ord, chr, int, and modulus. The ord function returns the ASCII code of a given character. The chr function returns the character of a given ASCII code. The int function converts a floating point number to an integer by removing decimals. The % symbol is used as the modulus operator to find the remainder of a division.
Python Substrings
A substring is a string contained within another string. The document provides an example of generating a 6 digit customer code from a customer's forename, surname, and year of birth by taking the first 2 letters of their forename, last 2 digits of their year of birth, and first 2 letters of their surname, as shown with the example customer "john smith 1995" having the code "jo95sm".
Variable Scope
Local variables are declared within sub-programs and can only be accessed and modified within that sub-program. Global variables are declared in the main program and can be accessed and modified by any code in the entire program. While global variables can be recognized program-wide, they should generally be avoided as the code is harder to read, debug, and track which parts are updating the variable.
Sub-programs
Computer programs can be broken down into smaller sub-programs or subroutines to make the code easier to write, understand and maintain. Sub-programs are independent blocks of code that carry out specific tasks and can be programmed and tested separately from the main program. Functions are sub-programs that return a value, while procedures produce an effect without returning a value. Parameters allow data to be passed from the main program to sub-programs.
Records in Python
This document discusses using records and dictionaries in Python to store and access data. It explains that a record allows combining multiple data objects, like storing a runner's name, bib number, and elite status in a single record rather than parallel arrays. This is implemented in Python using a dictionary with keys for each data item. It also describes storing multiple records in an array, creating an array of records to hold data about multiple runners.
Parallel arrays in python
This document discusses using parallel arrays in Python to store data about runners in a race. It describes initializing three parallel arrays to store the name, bib number, and elite status of each runner. Values can then be assigned to individual elements of the arrays to populate them with data, either by hardcoding, user input, or reading from a file. Once initialized, the parallel arrays allow accessing details about individual runners by index.

This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
