Mathematics in Computer Programming

Mathematics is applicable in various traditional fields of engineering: mechanical and electrical engineering are among them. Mathematics is used in computer engineering too.

Mathematical logic is used in the decision making, so it is used in computer programming. As Venn diagrams are helpful in understanding the concepts of logic, they are also helpful in the programming. For instance, De Morgan's laws are used in writing statements involving decisions and Venn diagrams are helpful in understanding these laws.

Computer

Calculations are also important in the science of computers. The text you read on the computer screen is presented in a particular format. Calculations are certainly needed for these.

Mathematics in Computer Programming

Geometry is used in the development of graphics. Actually a graphics screen resembles the co-ordinate plane. Just as we have points in the co-ordinate plane, we have pixels on the graphics screen. Though there are endlessly many points in any bounded part of the plane, while the number of pixels on the graphics screen is limited, yet the techniques of coordinate geometry can be used in drawing various figures on the graphics screen.

Various transformations play a part in the development of software. Two such transformations are famous as 'pop and push transformations'. As the graphs are useful in understanding different kinds of transformations, these help understand, in particular the Pop and Push transformations too.

The classical computer programming language namely 'the C language' makes a lot of use of mathematics. Different graphics commands of this language are based on the mathematical logic. The commands for making the background make use of hexadecimal numbers.

Five Tips on How to Enhance Your Computer Security

Network security has proved its importance in different businesses and industries. As people are becoming more engaged in the internet these days, the number of hackers and scammers has grown as well. There are a lot of types of security issues encountered online. These could be confusing and daunting, but they are rather important. Listed below are some excellent suggestions that could help ward off viruses, Trojans and other malicious codes that have the potential to steal your identity.

Choose a 64-bit Operating System

Computer

It is always best to upgrade to the latest operating systems as new operating systems have extended and enhanced features. If you are still using a Windows XP compared to the Windows 8 we have now, it is safe to conclude that XP performs inferiorly in terms of security. Moreover, even if you do upgrade to the latest OS, make sure that you choose the 64-bit version and not the 32-bit version, as the latter will be more prone to viruses and risks.

Five Tips on How to Enhance Your Computer Security

Avoid Using Administrator Accounts

The administrator account is the first account you see when you turn on a computer. This account has system administrator rights, but despite the rights, it is best to create a different account where you conduct your daily activities. In this way, even if you encounter a virus or any malicious code, it will not be able to entirely infiltrate your whole computer system that can potentially deteriorate network security. It is advisable to minimize the use of the administrator account.

Full Disk Encryption (FDE) on Laptops

Have the entire disk drive of your laptop encrypted. Having a standard password is not sufficient enough to keep hackers and thieves away/ the Full Disk Encryption or FDE provides an excellent layer of protection which works by securing the entire content of your computer and operating system.

Dump Office 2003 and Below

If you are still using the Microsoft Office 2003 version and below, it is imperative to upgrade right away. Documents from the old versions use binary file formats that can execute malicious codes. The new versions of the Microsoft Office come with features such as the protected read-only view which blocks the file from entering the computer if in any case it has viruses.

Updated Programs on PC

If you have third party programs installed in your PC including antivirus security programs, it is necessary to always keep them updated. Updates carry features which might be critical for network security.

Five Tips on How to Enhance Your Computer Security

Purchasing trees and animals may not be the best way to invest your money. You should first concentrate on crops and obtaining more land.

The more crops you have the more money you should be able to make.
