Software development life cycle
The software development life cycle is also known as software development performance. SDLC is a structure which is compulsory for development of software products.
Unified Process
It is a popular iterative and incremental software development process framework. The best-known and extensively documented refinement of the Unified Process. Unified process can be applied to different software organizations with different degrees of technical and managerial complexity across various areas and organizational cultures.

Most of the systems architecture will have hardware and software
Hardware:
Hardware refers to the physical parts or elements of a system/computer such as,
Processor (CPU): A CPU is the logic circuitry that responds to and processes the basic instructions that drive a computer. Like computation, Comparison, Data movement between memory, mass storage, and input/output (I/O) devices.
Storage device: Memory devices are one of the core elements of any computing device. They store virtually all the data and applications on a computer. Two types of storage devices
1. Primary Storage Devices: Generally smaller in size, are designed to hold data temporarily and are internal to the computer. They deliver the fastest data access speed, and include RAM and cache memory.
2. Secondary Storage Devices: These usually have large storage capability, and they store data permanently. They can be both internal and external to the computer, and they include the hard disk, compact disk drive and USB storage devices
Input/ Output device:
I/O devices allow the CPU to communicate with the outside world, including users and other information processing

Today we are working to summarize date representation, ways of data representation, data structure.
Data representation:
Data Representation refers to the methods used internally to represent data stored in a computer. Computers store lots of dissimilar types of information like numbers, text, graphics of many varieties and sound. All types of data stored in a computer are stored internally in the same simple format: a sequence of 0 's and 1 's.
How it is achieved..?
Data can be interpreted in many ways. To be processed by any device, data must be converted from its native format into a form suitable for the processing device. Modern computers represent information as electronic signals and implement processing devices by using electronic
Internal schema at the internal level to describe physical storage structures and access paths, typically uses a physical data model.
The Software Development Life Cycle is seldom used at my place of work. Unfortunately, recent developments in its use are deemed confidential. Due to this fact, this paper will examine in general terms one of the projects we are undertaking right now while at the same time attempting to maintain our confidentiality.
The waterfall methodology flows in a downward fashion, similar to the way water flows downwards, take developers from the high-level initial requirements gathering through the system testing and product shipment. The waterfall methodology create blueprints or plans for the optimal process for software developme...
This digital data takes the form of binary numbers, physically transferred by sending zero volts for zero or off and plus five volts for one or on. Certain binary numbers convey certain types of information, for example a certain binary number will tell the device that a note on a keyboard has been pressed. This is called a note on event and the
A software development methodology is a standard proven process which helps programmers, architects, system analysts and others to make a well controlled and an efficient progress in the high quality software development.
Whenever you press a key, click the mouse, or start an application, you're sending instructions to the CPU. The CPU is generally a two-inch square with a silicon chip located inside. The CPU fits into the motherboard's CPU socket, which is covered by the heat sink, an object that absorbs heat from the CPU. A processor's speed is measured in megahertz (MHz), or millions of instructions per second; and gigahertz (GHz), or billions of instructions per second. A faster processor can execute instructions more quickly. However, the actual speed of the computer depends on the speed of many different components—not just the processor.
A Study of WaterFall, a Software Development Model According to en.wikipedia.org Waterfall “is a software development model first proposed in 1970 by w.w. Royce, in which development is seen as flowing steadily through the phase of requirements analysis, design, implementation, testing, (validation), integration, and maintenance”. Waterfall method is the first published model of a software development process (1970). The basic principle is that the different processes (Analysis, Design, Coding, and Testing) are done sequentially. Output from one process is input to the next. Waterfall method advantages like simple, easy to understand and work with.
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).
Flash drives and Optical Storage are quick and easy ways to transfer data, and with all the technology that has been introduced over the years, these have many uses. There compact, portable, and very useful in many situations. To help understand these two topics more in depth, I will be explaining what they are, how they are used, and many other details.
CPU Stands for "Central Processing Unit." The CPU is the primary component of a computer that processes instructions. It runs the operating system and applications, constantly receiving input from the user or active software
Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change.
EVERYWHERE! Software is everywhere in today’s society. Yet, majority of the population don’t know how it is developed. Software development is the process of computer programming involved in creating and maintaining applications and frameworks resulting in a software product. It is used in various ways, accumulating the needs of different people and businesses. There are many methods that a team of software developers could use for generating their product, and each team must follow a methodology. Software development life cycle refers to the process that a software development follows to create their product. There are a diverse set of methodologies that a team of software developers can follow. The Waterfall methodology and the Agile methodology
There are four types of memory. These are the RAM, ROM, EEPROM and the Bootstrap loader. The RAM, also known as Random Access Memory, is the temporary space where the processor places the data while it is being used. This allows the computer to find the information that is being requested quickly without having to search the hard drive space. Once the information has been processed, and stored onto a permanent storage device, it is cleared out of the RAM. The RAM also houses the operating system while in
A computer is a combination of several parts. These parts are Random Access Memory (RAM), a Central Processing
In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
