System users often judge a system by its interface rather than its functionality
A poorly designed interface can cause a user to
make catastrophic errors
Poor user interface design is the reason why so
many software systems are never used
Learning Management Systems: The pros and cons of open-source LMSswendy cowan
Open-source learning management systems (LMS) are often the easiest to use and have a wealth of support documentation, but they require hosting the system and providing technical support. While LMS provide standardized interfaces, instant feedback, and convenience for educators, they can be restrictive and technology-driven. Vendor lock-in is also a problem if the LMS is switched. However, LMS allow copyrighted content behind passwords and communication tools. Downsides include lack of control, support, and access to student information if the vendor shuts down.

The key functionality of the system includes modules for administration, hostel management, and students to manage activities like bookings, bills, meal ordering, and notices.
An e-learning management system (LMS) is a software application for developing, delivering, and managing online courses and training programs. The main users of early LMS systems were students, but they now also serve business workers, medical practitioners, and marketing/advertising agencies. An LMS provides features like course registration, content management, assessments, grading, and engagement tools. Popular LMS platforms include Moodle and Edmodo, which offer calendars, file sharing, exams, and private online classrooms. LMS systems provide advantages like convenient training, reuse of materials, and choice for users, but may lack in-person interaction compared to traditional classrooms. Their use is growing among companies and schools as a way to extend learning
The University examination branch wants to maintain all the frequently asked questions in the database subject wise, to avail them to all the students. And they will update the questions as and when required. The primary goal of a Faq Desk is to provide an environment that is both convenient and efficient to use in retrieving and storing database information.
The database system must provide for the safety of the information stored, despite system crashes or attempts at unauthorized access. If data are to be shared among several users, the system must avoid possible anomalous results.
Dialogue is a process of communication between two or more agents where meaning must be considered to fulfill semantic and pragmatic rules. There are several rules for effective computer-user dialogue design including consistency, providing shortcuts and help facilities, and reducing short-term memory load. Effective dialogue relies on feedback, error handling, and allowing easy cancellation of actions. Common dialogue types include command languages, natural language, direct manipulation, menus, and forms. Each type has advantages and disadvantages depending on the context and task.

Information and network security 28 blowfishVaibhav Khanna
Blowfish is a symmetric block cipher designed as a replacement for DES. It encrypts data in 64-bit blocks using a variable-length key. The algorithm uses substitution boxes and a complex key schedule to encrypt the data in multiple rounds. It is very fast, uses little memory, and is resistant to cryptanalysis due to its complex key schedule and substitution boxes.
Information and network security 27 triple desVaibhav Khanna
Part of what Triple DES does is to protect against brute force attacks. The original DES symmetric encryption algorithm specified the use of 56-bit keys -- not enough, by 1999, to protect against practical brute force attacks. Triple DES specifies the use of three distinct DES keys, for a total key length of 168 bits

The Ultimate Guide to Top 36 DevOps Testing Tools for 2024.pdfkalichargn70th171
Testing is pivotal in the DevOps framework, serving as a linchpin for early bug detection and the seamless transition from code creation to deployment.
DevOps teams frequently adopt a Continuous Integration/Continuous Deployment (CI/CD) methodology to automate processes. A robust testing strategy empowers them to confidently deploy new code, backed by assurance that it has passed rigorous unit and performance tests.

Software engineering 19 user interface design elements
1. Software Engineering: 19
User interface Design Elements
Prof Neeraj Bhargava
Vaibhav Khanna
Department of Computer Science
School of Engineering and Systems Sciences
Maharshi Dayanand Saraswati University Ajmer
2. User-system interaction
• Two problems must be addressed in
interactive systems design
– How should information from the user be
provided to the computer system?
– How should information from the computer
system be presented to the user?
• User interaction and information presentation
may be integrated through a coherent
framework such as a user interface metaphor
3. Interaction styles
1. Direct manipulation
2. Menu selection
3. Form fill-in
4. Command language
5. Natural language
4. 1. Direct manipulation Advantages
• Users feel in control of the computer and are
less likely to be intimidated by it
• User learning time is relatively short
• Users get immediate feedback on their actions
so mistakes can be quickly detected and
corrected
5. 1. Direct manipulation problems
• The derivation of an appropriate information
space model can be very difficult
• Given that users have a large information
space, what facilities for navigating around
that space should be provided?
• Direct manipulation interfaces can be complex
to program and make heavy demands on the
computer system
6. 2.Menu systems
• Users make a selection from a list of
possibilities presented to them by the system
• The selection may be made by pointing and
clicking with a mouse, using cursor keys or by
typing the name of the selection
• May make use of simple-to-use terminals such
as touchscreens
7. 2. Menu systems Advantages
• Users need not remember command names
as they are always presented with a list of
valid commands
• Typing effort is minimal
• User errors are trapped by the interface
• Context-dependent help can be provided. The
user’s context is indicated by the current
menu selection
8. Problems with menu systems
• Actions which involve logical conjunction
(and) or disjunction (or) are awkward to
represent
• Menu systems are best suited to presenting a
small number of choices. If there are many
choices, some menu structuring facility must
be used
• Experienced users find menus slower than
command language
10. 4. Command interfaces
• User types commands to give instructions to
the system e.g. UNIX
• May be implemented using cheap terminals.
• Easy to process using compiler techniques
• Commands of arbitrary complexity can be
created by command combination
• Concise interfaces requiring minimal typing
can be created
11. Problems with command interfaces
• Users have to learn and remember a
command language. Command interfaces are
therefore unsuitable for occasional users
• Users make errors in command. An error
detection and recovery system is required
• System interaction is through a keyboard so
typing ability is required
12. Command languages
• Often preferred by experienced users because
they allow for faster interaction with the
system
• Not suitable for casual or inexperienced users
• May be provided as an alternative to menu
commands (keyboard shortcuts). In some
cases, a command language interface and a
menu-based interface are supported at the
same time.
13. 5. Natural language interfaces
• The user types a command in a natural
language.
• Generally, the vocabulary is limited and these
systems are confined to specific application
domains
• NL processing technology is now good enough
to make these interfaces effective for casual
users but experienced users find that they
require too much typing
14. Assignment
• Discuss in detail the various interaction style
elements in user interface design
• Thank You
