Dtlp 1 introduction to computer
A computer is an electronic device that manipulates data through processing. It can store, retrieve, and process information. Computers have hardware components that can be touched like processors and memory, as well as software programs like operating systems and applications. Information sent to a computer is input, which is processed and then output in some form like on a screen. Storage devices are used to permanently or temporarily hold data and come in primary and secondary forms. Computers have evolved through generations from early vacuum tube machines to today's integrated circuit computers and beyond to artificial intelligence.

This document discusses a study on students' attitudes towards computers and their relationship to computer literacy. The study involved 1004 students from Lithuanian universities and colleges. Based on the results, the researchers identified statistical types of students based on their emotional-motivational relationship with computers. They also examined links between these relationship types and students' actual computer literacy levels. The researchers found some types had more positive feelings towards computers, which helped them perform difficult tasks and achieve better academic results, showing the importance of non-cognitive traits on computer literacy.

The document provides an overview of computer evolution and hardware components. It can be summarized as follows:
1) Computer hardware evolved rapidly from early vacuum tube computers to transistor-based systems to today's microprocessor-powered devices. Moore's Law predicted that processing power would double every 18 months.
2) The microprocessor revolutionized computing, allowing the development of personal computers that were as powerful as room-sized mainframes.
3) Modern computer systems consist of an input devices, a central processing unit (CPU), memory, storage devices, and output devices connected via buses. The CPU processes data and memory temporarily stores programs and data.

Fundamental note New
The document provides an overview of the history and evolution of computers from the 1800s to present day. It discusses early mechanical calculating devices, followed by the development of vacuum tube-based computers in the 1940s-1950s. Transistor-based computers of the 1950s-1960s were smaller and more reliable. Integrated circuits were introduced in the 1960s-1970s, allowing for smaller and more powerful computers. Microprocessors were developed in the 1970s, leading to personal computers. The document also covers classifications of computers and their components.
ENIC Symbols
The document discusses the symbols used by the ENIC group to represent their identity, including their name and a photo of people using the ENIAC machine. The ENIAC was the first electronic computer used for general purposes like solving numerical problems. The symbols reflect honoring achievements in the field while looking toward future development. The group has a good team dynamic with strong bonds and everyone understands their roles, having worked together since 2017.
Chapter 1.pptx
1. A computer is an electronic device capable of performing arithmetic and logical operations by processing data in binary form. It can choose, copy, move, and manipulate symbols like numbers and text.
2. Compared to humans, computers have nearly perfect memory, are very fast, accurate, and reliable. However, computers cannot think creatively like humans.
3. Computers are now used in nearly all aspects of life from education and business to entertainment and healthcare. They have become indispensable tools that save time and increase productivity.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

- 1. CHAPTER 2:LOOKING AT COMPUTERS By: Darika Brown
- 2. COMPUTERS What is a computer and who designed the first computer? A computer is a data processing device that performs four major functions: input, process, output, and storage. The first computer known as a ENIAC was designed by a physicist named John William Mauchly and a man named John Adam Presper "Pres" Eckert Jr. John was an American Electrical engineer. What gave this to incredible guys the idea to create such an outstanding device that would later change the world? Presper was a student who became a teacher because he was interested in engineering and he began to design his first digital computer out of vacuum tubes. So why is this so important? This is where the world changed in a technology sense. History is very important just like the history of a computer.
- 3. THE ELECTRONIC NUMERICAL INTEGRATOR AND COMPUTER
- 4. WHAT ARE SOME OF THE IMPORTANT FUNCTIONS OF A COMPUTER? Input and output is when the computer exchanges information with the outside world. For example when someone is typing information into a computer that’s input but when a person is sending a email that’s called output information. Data is when information is stored by the computer. Something interesting that I learned was that computers have languages too; there called binary language. Binary language a numeric system that only uses two digits which are one and zero. In computers when it comes to binary they process data and calculate numbers using one and zero. What is a byte in a computer? A byte is a unit of measurement to measure data, a byte also made of eight binary bites. These bites can only consists of ones and zeros. Monitors help the user interact using the keyboard or mouse. Also the monitor opens up programs for the user to explore. A hard drive is different from the random access memory, the hard drive actually stores the files and documents which is the data. The hard drive is small but can hold over a 100 GB if possible.
- 5. New school v.s. old school.
- 6. R.A.M: Random access memory. What does the random access memory do? The random access memory holds the data, operating system, and the application programs as long as the computer is running. When the computer shuts down the data in R.A.M is destroyed or disappears. R.O.M is the compete opposite from R.A.M, R.O.M is a permanent type of memory. Its responsible for hosing institutions to help start up a computer.
- 7. Images……
- 8. Conclusion Computers had a great impact on the world during war world II. Computers came along way from since then and they have helped the world connect with people all across the world. We should thank people like philosophers, inventors, engineers, mathematics, and scholars for taking the time out to figure out ways how to improve technology. With their help and with constantly learning ways to improve more we have the best ways to get things done, like homework. Before there where digital computers we had calculating machines that helped the veterans connect with different countries. These machines helped evolve into the computers we use today to communicate with family, jobs, and other important duties. As an individual computers helped me in some many ways like signing up for opportunities to win scholarships. Technology has come along way and it doesn’t stop here. Where would we be without computers.
