Programming Vs Computer Science

Computer science deals with the basic structure of a computer and is more theoretical. As a result, it is more flexible in terms of specialization, with an emphasis on math and science. When, computers had just been introduced, computer science degrees were conducted within the math department. Since computers have become an essential part of society, the branch degree has since expanded, but the focus remains unchanged. 

Some of the most common programs offered in computer science include programming, numerical analysis, algorithms and data structures, computer systems principles, the software process, and theory of computers.  
Computer engineering deals with computer systems and understanding the most practical approach to computer development and use. Although, computer engineers focus on the software, a computer engineer is also required to be familiar with the hardware.

 Additionaly, Computer engineering combines electrical engineering and science, with a focus on software-hardware interactions. Some of the most common programs offered in computer engineering include processor interfacing, digital logical design, thermodynamics, power management, solid state physics, and magnetic fields. Degrees in computer engineering are highly customizable, as programs often cover a wide range of interests. Ultimately you are in control of your own degree as you focus on your interests, this customizable degree will propel your profession into your desired career direction.

Computer Science Vs Information Systems

If students want to ensure that their computer science education is as well-rounded as possible, then a great deal of headway can be made by spending time looking into reliable computer science blogs. While the material in a computer science undergraduate course can be very dense, there is the risk of allowing one’s education to become too insular in terms of the source that it comes from. 

By reading blogs about computer science definition with alternative computer science articles, students can ensure that they have a more all-inclusive outlook on the subject as a whole.

 Not only will students be more capable of understanding some of the most complex topics about computer science in a more accurate way, but they’ll also be able to contribute more to the field in general simply by virtue of having learned from a wider pool of professionals than only those directing their academic programs.

The following are just a few examples of some of the best computer science blogs for students who want to read articles about computer science that go beyond what they are learning in their general curriculum.

Computer Science Vs Software Engineering

Often times individuals can find themselves comparing software engineer and computer science. While these fields look similar initially, their differences become obvious quickly when some investigating is done. The most important question is: which profession is better in the long run?

Both software engineer and computer science, are involved with computer software, along with software development and other related fields. Those interested in a career centered on software development and computer technology often focus on one of two majors: computer science or software engineering (sometimes referred to as software development, but the two are not synonymous).

The primary difference is that computer science was originally a sub-branch of mathematics. Computer science deals with the basic structure of a computer and is more theoretical. Hence, it is more malleable in terms of specialization, with the emphasis on math and science. Software engineering is a field concerned with the application of engineering processes to the creation, maintenance, and design of software for a variety of different purposes. A software engineer designs customized applications per the requirements of an organization.

One of the main benefits of these vocations is that it offers the freedom of freelance engineering.  With the increasing popularity of the gig economy, computer scientist and software engineers are able to reap the benefits as a freelance or contract worker.

As for which job is the right fit for you, it comes down to your preference. While both professions are computer-related, the emphasis is completely different. Therefore, your interests should be considered then think about where you see yourself ten years from now. We’ll go into more depth about each industry, along with the average computer science salary and software engineer salary.

Characteristics Of Wireless Network

The term  wireless network  (Wireless network  in  English ) is a term used in telecommunications to designate the connection of  nodes  without the need of a physical connection ( cables ), this is given by means of  electromagnetic waves .Wireless Lan protocal Transmission and reception are done through  ports .

One of its main advantages is notable in the costs, since all ethernet cable  and physical connections between nodes are eliminated  , but it also has a considerable disadvantage since for this type of network you must have a   much more demanding and robust security to avoid to intruders.

Characteristics:

Depending on the frequency range used to transmit, the transmission medium may be  radio waves ,   terrestrial or satellite microwaves , and  infrared , for example. Depending on the medium, the wireless network will have some characteristics or others:

·          Radio waves:  the  electromagnetic waves  are omnidirectional, so they are not necessary  satellite dishes . The transmission is not sensitive to the attenuations caused by rain since it operates at frequencies not too high. In this range are the bands from the  ELF  that goes from 3 to 30  Hz , to the UHF band   that goes from 300 to 3000  MHz , that is, it comprises the radio spectrum of 30 - 3000000000 Hz.

·          Terrestrial microwave:  satellite dishes with an approximate diameter of about three meters are used. They have a coverage of kilometers, but with the disadvantage that the transmitter and receiver must be perfectly aligned. Therefore, they are used to use point-to-point links   over short distances. In this case, the attenuation produced by rain is more important since it operates at a higher frequency. Microwaves comprise frequencies from 1 to 300  GHz .

·          Microwave by satellite:  links are made between two or more ground stations called base stations. The  satellite  receives the signal (called ascending signal) in a frequency band, amplifies it and retransmits it in another band (descending signal). Each satellite operates in specific bands. Microwave frequencies, both terrestrial and satellite, with infrared and high-frequency radio waves mix quite a bit, so there may be interference with communications on certain frequencies.

Audits in industrial wireless communications

Today, the wireless communication methods used in industrial environments for communication between the various devices that make up the industrial process are numerous and widespread. Among them are Wi-Fi, WiMAX and WirelessHART. From CERTSI a guide has already been published in which the characteristics and good security practices of these protocols were presented and analyzed.

Security audit of industrial wireless protocols
An industrial wireless communications audit is a process similar to a wireless security audit in corporate environments, in which the particularities of specific SCI environments and protocols must be taken into account. The main objective is to determine the security level of the wireless computing infrastructure of the client company; limited connection ethernet for this, different tests are carried out with the help of various applications with the aim of finding possible failures and / or weaknesses in the security of the wireless network. Care must be taken when conducting intrusion tests or vulnerability assessments, since they could compromise the security of the system, as well as the continuity of industrial processes.

Advantages of performing industrial wireless protocol audits
Industrial communication networks may be affected by various security problems and threats, some of them critical to the industrial process, such as a denial of service. That is why, performing security audits of these wireless networks will raise the state of communications security in a way that will allow:

• Detect default settings.
• Detect possible vulnerabilities of the devices.
• Detect problems in controlling access to networks.
• Detect errors in the implementation and deployment of networks in a way that identifies countermeasures to be applied for mitigation.
• Reduce the impact of possible attacks and security incidents.
• Implement corrective actions.
• Check the version in use and its potential vulnerabilities
