The Internet Of Things

The Internet of Things is a concept of a computer network of physical objects equipped with built-in technologies for interacting with each other or with the external environment, considering the organization of such networks as a phenomenon that can restructure economic and social processes, eliminating the need for human participation from part of actions and operations. IoT technology has had a significant impact on the development of information technology and other industries. According to Forbes, the Internet of Things market is expected to reach $520 billion in 2021, up from $235 billion in 2017, indicating a continued growth in demand for such devices in the future. Gartner Research also estimates that the number of devices connected to the Internet will reach 25 billion by 2021, up from 8.4 billion in 2017. Network with IoT devices connected is an indispensable prey for intruders. There are many ways to attack IoT devices. In this article, the authors have identified several methods of protection. Among them, network interaction monitoring through the analysis is highlighted. The paper also describes how to apply this method in practice.

Improve Instruction

The Materials Science Department at Iowa State University has developed a laboratory designed to improve instruction in the use of the scanning electron microscope (SEM). The laboratory makes use of a computer network and a series of remote workstations in a classroom setting to provide students with increased hands-on access to the SEM. The laboratory has also been equipped such that distance learning via the internet can be achieved.A view of the laboratory is shown in Figure 1. The laboratory consists of a JEOL 6100 SEM, a Macintosh Quadra computer that acts as a server for the network and controls the energy dispersive spectrometer (EDS), four Macintosh computers that act as remote workstations, and a fifth Macintosh that acts as an internet server. A schematic layout of the classroom is shown in Figure 2. The workstations are connected directly to the SEM to allow joystick and computer control of the microscope. An ethernet connection between the Quadra and the workstations allows students seated there to operate the EDS. Control of the microscope and joystick is passed between the workstations by a switch-box assembly that resides at the microscope console. When the switch-box assembly is activated a direct serial line is established between the specified workstation and the microscope via the SEM’s RS-232.

The purpose of this study wants to examine the effect of System Quality (SysQua) to Service Quality (ServQua), System Quality (SysQua) to Work Performance (WorkPef), and Service Quality (ServQua) to Work Performance (WorkPef). The object in this research is MYOB accounting software. The data gathers with quesionnaires in 2 types, physicals (paper) and online (using Google form).  From 315 questionnaires distributed consisted of 194 respondents through online, and 116 respondents through paper form. All the questionnaires are returned. The obtained data were analyzed using structural equation modelling. The result of data analysis showed that the System Quality (SysQua) have positive significant effect on the Service Quality (ServQua), Service Quality (ServQua) have positive significant effect on Work Performance (WorkPef), and System Quality (SysQua) have positive significant effect on Work Performance (WorkPef). The overall result indicates that MYOB have a good quality and related to user performance. Specifically, the user refers to basic user, which is university student.   Tujuan penelitian ini adalah untuk menguji pengaruh hubungan System Quality (SysQua) terhadap Service Quality (ServQua), System Quality (SysQua) terhadap Work Performance (WorkPef) dan Service Quality (ServQua) terhadap Work Performance (WorkPef). Objek pada penelitian ini yaitu software akuntansi MYOB. Teknik pengumpulan data menggunakan metode purposive sampling. Perolehan data dengan kuesioner terdiri dari 2 tipe yaitu fisik (kertas) dan online (menggunakan Google form). Dari 315 kuesioner yang tersebar terdiri dari 194 responden melalui online dan 116 responden melalui kertas. Semua kuesioner telah kembali. Pengelolahan data menggunakan Structural Equation Model. Hasil dari penelitian ini menunjukkan bahwa System Quality (SysQua) berpengaruh positif signifikan terhadap Service Quality (ServQua), Service Quality (ServQua) berpengaruh positif signifikan terhadap Work Performance (WorkPef), dan System Quality (SysQua) berpengaruh positif signifikan terhadap Work Performance (WorkPef). Hasil keseluruhan menunjukkan bahwa MYOB memiliki kualitas yang baik dan terkait dengan kinerja pengguna. Secara khusus, pengguna mengacu kepada pengguna tingkat dasar, yang merupakan mahasiswa.
