What is CAD?

Computer-aided design (CAD) is the use of computer programs or computer systems that aim to create, modify, analyze, optimize and document two or three-dimensional (that is 2D or 3D) graphical representations of physical objects as an alternative to manual drafts and product prototypes. It is widely used in electrical, mechanical, chemical engineering, among others. For example, it is used in electrical engineering to make electrical drawings regarding different projects such as Residential Projects, industrial projects, etc.

What are some of its advantages over other design systems?

CAD is widely used to increase the productivity of the designer as well as improve the quality of design, improve communications through documentation, and to create a database for manufacturing.
It is used throughout the engineering process. From conceptual product design and layout through assembly analysis to manufacturing method definition. The method CAD enables and ensures engineers to interactively test design variants with minimal physical prototypes to achieve:

1. Lower product development costs
2. Greater speed
3. Increased productivity
4. Quality assurance
5. Accelerated time-to-market

In this technological age, costs, productivity, speed, quality and time are topics very important to companies. These topics are optimized using CAD. Manual drafts and product prototypes translate into a poor productivity nowadays.

What is the difference between servicing and repair?

There are a lot of products that are designed to be fully serviceable and repairable. These products (such as a watch, smartphone, car, etc) are subjected to a wide variety of daily stresses and strains. When a part of the product needs replacing, this is a timely opportunity to ensure that any progressive wear and tear from external elements are addressed. By carefully assessing each product, checking its parts, addressing any worn parts or gaskets, ensures that the product is in perfect working order and that it always functions efficiently. This is related to service.
On the other hand, if the product has been accidentally damaged, suffered a fault, then it is necessary to repair the product. This is related to repair
So, the difference between servicing and repair is that the first one is related to maintenance and the second one involves fixing things when the product is damaged.

Why are both important in technological products?

Creating the most popular product of the year will make consumers and investors happy. Many of the best-selling products were first in a new category. The purpose of the products is to continue to dominate their markets. So, it is important that they be easy for maintenance and hard to be damaged.

SCAREWARE

Scareware is a malware that tricks victims to buy software by displaying fake virus alerts. A scareware infected PC may get pop-ups of fake malware threats and to get rid of those, users are prompted to purchase a fake anti-malware software.

KEYLOGGER

Also known as a keystroke logger, Keyloggers can track the real-time activity of a user on his computer. Keylogger runs in the background and records all keystrokes made by a user and passes the information to the hacker with the motive to steal password and banking details.

ROOTKIT

A rootkit is considered extremely dangerous as they appear to be legitimate files and deceives the computer user. Rootkit masks viruses and worms and makes them appear as necessary files. These are very difficult to remove and only an antivirus with the anti-rootkit feature can remove a rootkit.

Tips for Best Computer Security

For best computer security, you must follow certain guidelines, which are also called computer best practices. 1. Use the best antivirus software, which not only provides protection to your PC but also internet protection and guards against cyber threats. 2.
