Precautionary measures to be observed when using ICT tools

Dafna11 [192]

Answer:

ICT is the abbreviated form of Information and Communication. It included different technologies like mobile phones, computers, USBs etc.

Following are two precautionary measures which should be observed when using any kind of ICT:

Use of Antivirus: It can used to protect anything placed inside the technology especially from hacking and viruses which can create many issues.
Backup Data: Creating a backup of the data stored in the device is important as it can be recalled when the device malfunctions. Backup of the data can be created through using USBs, CDs etc or through cloud storage

PLTW IM Chapter 1.2-1.3 i need this please

Luden [163]

Answer:

Biomedical Science

The application of the principles of the natural sciences, especially biology and physiology to clinical medicine

Control group

The group in an experiment where the independent variable being tested is not applied so that it may serve as a standard for comparison against the experimental group where the independent variable is applied.

Dependent Variable

The measurable affect, outcome, or response in which the research is interested.

Experiment

A research study conducted to determine the effect that one variable has upon another variable

Forensic Science

The application of scientific knowledge to questions of civil and criminal law

Hypothesis

Clear prediction of anticipated results of an experiment

Independent Variable

The variable that is varied or manipulated by the researcher

Negative control

Control group where the conditions produce a negative outcome. Negative control groups help identify outside influences which may be present that were not accounted for when the procedure was created

Personal protective equipment

Specialized clothing or equipment, worn by an employee for protection against infectious materials.(as defined by OSHA)

Positive control

Group expected to have a positive result, allowing the researcher to show that the experiment set up was capable of producing results.

Adenine

A component of nucleic acids, energy carrying molecule such as ATP, and certain co enzymes. Chemically it is a purine base.

Chromosome

Any of the usually linear bodies in the nucleus that contain genetic material.

Cytosine

A component of nucleic acids that carries hereditary information in DNA and RNA in cells . Chemically it is a pyrimidine base.

Deoroxyribonucleic acid

A double-stranded helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell proteins

Gel electrophoresis

The separation of nucleic acids or proteins, on the basis of their size and electrical charge, by measuring their movement through an electrical field in a gel.

Gene

A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA.( or RNA in some viruses).

Guanine

A component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically it is a purine base.

Helix

Something in spiral form.

Model

A simplified version of something complex used, for example, to analyze and solve problems or make predictions.

Nucleotide

A building block of DNA, consisting of a 5 carbon sugar convalently bonded to a nitrogenous base and a phosphate group.

Restriction enzymes

A degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA

Restriction fragment length polyphorisms (RFLPs)

Differences in DNA sequences on homologous chromosomes that can result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes)

Thymine

A component of nucleic acid that carries hereditary information in DNA cells. Chemically, it is a pyrimidine base

Autopsy

An examination of the body after death usually with such dissections as will expose the vital organs for determining the cause of death

Bibliography

a document showing all the sources used to research information

Citation

A written reference to a specific work by a particular author or creator which identifies the document in which the work may be found

Documentation

The act of creating citations to identify resources used in writing a work

Health Insurance Portability and Accountability Act (HIPAA)

A comprehensive set of standards and practices designed to give patients specific rights regarding their personal health information

Medical examiner

A physician who performs an autopsy when death may be accidental or violent. He/she may also serve in some jurisdictions as the coroner.

Explanation:

This is what I found when I searched up pltw chapter 1.2-1.3 answers.

I did this because there was not really a question in there.

PS:

I'm sorry if this is too long for you to read.

Give me brainliest, if you want to, that is.

A(n) ____ is a computer that requests and uses network resources from a(n) ____.

Crazy boy [7]

A(n) client exists a computer that requests and utilizes network resources from a(n) server.

<h3>What is a computer network?</h3>

A computer network is a collection of computers that share resources that are available on or provided by network nodes.
The computers communicate with one another via digital links using standard communication protocols.
These links are made up of telecommunication network technologies that are based on physically wired, optical, and wireless radio-frequency means and can be configured in a variety of network topologies.
Nodes in a computer network can be personal computers, servers, networking equipment, or other specialized or general-purpose hosts.
They can be identified by network addresses and have hostnames.
Local-area networks (LANs) and wide-area networks (WANs) are the two basic network types.

A(n) client exists a computer that requests and utilizes network resources from a(n) server.

The most commonly used network topology where network endpoints connect to a central device is called

arsen [322]

That would be a star network. A star network isn't necessarily shaped like a star, of course, but like you mention this topology has a central device, usually a server of some sorts, and then many different endpoints coming out of that central device, such as the client computers for the server.
