The Unistep IRP Elexol EtherIO 24 Module is a network board that enables multiple devices to connect to an Ethernet network, communicate with each other, and relay information when changes occur. The IRP module is a micro-controller, integrated with many features for interacting with devices connected on a generic local area network; this module was designed to be used in conjunction with other network devices or modules. Some of the applications for the device include industrial automation, digital input and output functions, system monitoring, remote data accessing, controlled machinery, and remote power control.
The EtherIO 24 IRP module is currently manufactured by Elexol and is manufactured by Unistep technologies. The IRP module is a network based, micro-controller that was designed for communication over Ethernet using the UDP/IP protocol to control input and output signal lines. Any network can be used with the module that supports TCP/IP and connecting to an Internet router enables communication to any Internet enabled device. Other supported protocols include ARP, BOOTP, DHCP, and ICMP. The MAC address is pre-assigned on every device, but the IP address can be assigned either fixed using EEPROM commands or dynamic from a DHCP server using the

Reading the data stored on the module can be done by polling, which is better suited for simple programs, or interrupt, which is used in more advanced programming. Identifying the modules IP address allocated from the DHCP server, configuring the ports and signal lines (input: TTL, CMOS, Schmitt Trigger or output), read/write to the ports, and EEPROM memory usage are additional programming options for the module. Some advanced programming for the module include setting up a fixed IP address, default power up state, auto scan mode, and resetting the
Mobile devices will benefit from MRAM as it has less power demands, allowing for much longer uses on a single charge. Further, MRAM’s durability and low power requirements make it ideal for defense and aerospace technologies as well as for the primary data storage technology for satellites. NVE Corp. has patents on advanced MRAM designs which include vertical transport MRAM, magnetothermal MRAM, and spin-momentum transfer MRAM. These advanced designs aim to resolve the current hindrances of MRAM technology; mainly, lowering manufacturing costs while increasing memory density. Due to MRAM’s more expensive production costs and larger relative size than DRAM and Flash RAM, they are slowly being integrated into electronic devices.
The SIEM is a log management system where every network device, server or workstation will send their logs for storage, correlation and analysis. The analysis will provide alerts similar to the NIDS and HIDS. In addition, the log correlation could be used to help track where and when malicious activity has occurred and on what system(s) the activity was seen. The combination of the NIDS, HIDS and SIEM will provide a good array of detection for malicious users, software or unauthorized system access.

Throughout its history, Intel has centered its strategy on the tenets of technological leadership and innovation (Burgelman, 1994). Intel established its reputation for taking calculated risks early on in 1969 by pioneering the metal-oxide semiconductor (MOS) processing technology. This new process technology enabled Intel to increase the number of circuits while simultaneously being able to reduce the cost-per-bit by tenfold. In 1970, Intel once again led the way with the introduction of the world’s first DRAM. While other companies had designed functioning DRAMs, they had failed to develop a process technology that would allow manufacturing of the devices to be commercially viable. By 1972, unit sales for the 1103, Intel’s original DRAM, had accounted for over 90% of the company’s $23.4 million revenue (Cogan & Burgelman, 2004).
In order to have a greater understanding of the terminology and descriptions offered in this paper, we must first understand what a network switch is. A brief definition of a network switch is a computer networking device that connects network segments. It uses the logic of a Network bridge, but allows a physical and logical star topology. It is often used to replace network hubs. A switch is also often referred to as an intelligent hub.
Token ring networks had significantly superior performance and reliability compared to early shared-media implementations of Ethernet (IEEE 802.3), and were widely adopted as a higher-performance alternative to shared-media Ethernet.
The OSI model provided for a solution to this problem. The model organized those tasks that are essential for computer network operation, into seven groups. These groups were called layers. All manufacturers of computing equipment were recommended to make their products compliant with the OSI model. This meant that each computing product was to perform the functions associated with a specific layer within the model; any method of accomplishing these functions was acceptable. In a network composed of equipment that operated according to OSI guidelines, a separate product would be used to perform each layer of OSI functionality. Thus, all elements of the network would be aware of the specific jobs performed by every other network element; this would allow for compatibility between networking products that were created by different vendors. By designing networks according to OSI guidelines, the networker was able to combine any group of products, made by any number of vendors, into a functioning computer network (Stamper 28).
When desktop computers and Local Area Networks (LAN) appeared in the 1980’s, they were small scale and being somewhat complex they required hands on technical skills, so were acquired in limited quantities. The low cash costs also meant they were often purchased without the approval of senior management.
Clearly, in the time available, I have not been able to carry out a full technical review of the manual. However, I have used my local knowledge and past experience to review the manual with critical eye, with the aim of identifying information and technology gaps, any uncertainties, misconceptions or missed opportunities.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
This paper covers details of available memory and their capacities and latencies. Paper also describes the current and historical information of memory which will give an idea of memory requirements for an operating system.
It improves the average memory access time by 16.9% and decreases the power consumption by 15.2%. Whereas the architecture with DRAM reduced the average memory access time 2%, this is not that good but shows a large decreasing in the power consumption 33%. PRAM is the worst between them. Whereas it perform good when cache capacity is small but it still the worst memory access time, although its power consumption is the least it doesn’t suitable to be as a cache memory [4].
Electronic devices are easy carry and a device can carry thousands of books and a large content of data.
