1. System - A system is a group of interacting or interrelated elements that act according to a set of
rules to form a unified whole.
2. System Integration - System Integration is the process of integrating all the physical and virtual
components of an organisation's system.
3. System Architecture - A system architecture is the conceptual model that defines the structure,
behavior, and more views of a system.
4. Project - a project is a series of tasks that need to be completed to reach a specific outcome.
5. System Modeling- Systems modeling or system modeling is the interdisciplinary study of the use
of models to conceptualize and construct systems in business and IT development.
6. Context Models- A context model defines how context data are structured and maintained.
7. System boundaries- All components of an information system to be authorized for operation by
an authorizing official and excludes separately authorized systems, to which the information
system is connected.
8. Use cases- In software and systems engineering, the phrase use case is a polyseme with two
senses: A usage scenario for a piece of software; often used in the plural to suggest situations
where a piece of software may be useful.
9. UML- The Unified Modeling Language is a general-purpose, developmental modeling language
in the field of software engineering that is intended to provide a standard way to visualize the
design of a system.
10. Von Neumann Architecture- used the idea of storing program instructions and data in main
memory and moving them between memory and the processor.
11. Common CPU components





control unit (CU)- it fetches, decodes and executes instructions
arithmetic logic unit (ALU)- It performs arithmetic and logical operations (decisions). The ALU
is where calculations are done and where decisions are made.
Registers- are small amounts of high-speed memory contained within the CPU.
Cache- Cache is a small amount of high-speed random access memory (RAM) built directly
within the processor.
Buses- A bus is a high-speed internal connection
Clock- The CPU contains a clock which is used to coordinate all of the computer's components.
12. The purpose/function of CPU- the CPU is the brain of a computer, containing all the circuitry
needed to process input, store data, and output results.

1. 7 Phases of system Development life Cycle.

Planning- Planning helps systems engineers and developers identify whether a new
system can help a business achieve its strategic objectives.
 System Analysis - The systems analysis phase is less theoretical and focuses more on
practical application.
 System Design- During the system's design phase, you and your team complete the
detailed planning of the system you're developing.
 Development- During development, you begin the functional creation of the new system.
This provides the first opportunity for practical assessment of the system as it develops.
 System Testing and Integration- Testing during development and before formal release is
an important step for maintaining the quality of a project.
 Implementation- The implementation phase is your opportunity to introduce the
developed system to the end users.
 Operation and Maintenance- The operation and maintenance phase occurs during the
effective use of the product by end users. Providing updates and adjustments to the
software system after release allows you to alter it to better match the needs of users.
2. 5 Types of UML Diagrams That are The most useful for System Modeling.
 Class Diagram- Class diagrams are the main building block of any object-oriented
solution. It shows the classes in a system, attributes, and operations of each class and the
relationship between each class.
 Component Diagram- displays the structural relationship of components of a software
system.
 Deployment Diagram- shows the hardware of your system and the software in that
hardware.
 Package Diagram- shows the dependencies between different packages in a system.
 Activity Diagram- They can be used to describe the business workflow or the operational
workflow of any component in a system.
3. Types of General Purpose Computer- A general-purpose computer is one that, given the
application and required time, should be able to perform the most common computing tasks.
 Desktop- A desktop computer is a personal computer designed for regular use at a single
location on or near a desk due to its size and power requirements.
 Smartphone- A smartphone is a portable computer device that combines mobile
telephone and computing functions into one unit.
4. Job Roles of a System Integrator Assess information technology (IT) requirements
 Build computing systems for clients by selecting appropriate hardware, software and storage
products
 Purchase and integrate subsystems from multiple vendors
 Configure systems according to an organization's needs
 Mange cybersecurity
 Script languages and programming tools
 Troubleshoot hardware and software issues
 Understand databases and web-based technologies
Test V.
1. Which is a better Computer Lab? All high-end Desktop PC or a mix of General Purpose
Computer?Why?
In a computer lab we dont need a high-end Deskop Pc because it only for gaming but us
student we need a convenient Pc for us and i choose General Purpose Computer because it
can be used for a wide range of tasks and are also often more affordable than special-purpose
computers, as they can be used for a variety of tasks.
