...Introduction Technology and Livelihood Education (TLE) is one of the nomenclature in the implementation of the K to 12 Basic Education Program (BEP) composed of four components namely: Agri-Fishery Arts, Home Economics, Industrial Arts and Information and Communication Technology (ICT). In this module, the focus is on an ICT mini-course – Computer Hardware Servicing. Now that the workforce is behind in equating the number of available jobs, the Department of Education is revitalizing its resources to prepare the young minds by honing their skills as future hardware service providers. Thus, this module seeks to provide students with the knowledge, skills and motivation in the field of hardware servicing. In this course, you will be introduced to different learning activities preparing you to be skillful before you take the plunge into the world of work as a hardware service provider and to feel more confident while providing support where needed. Indeed, as learners of hardware servicing, you are a crucial link in the emergency response process. Ideally, everyone should know what to do in an emergency situation, but proper training can help an individual provide basic care. This module is specifically crafted to focus on Process and Delivery enriched with hands- on activities that will assess your level in terms of skills and knowledge. Learning procedures are divided into different sections such as: What to Know, What to Process, What to...

This application is an open source tool that automates network exploration to perform several different types of security audit scans of large IP networks (LAB 3, CTU. 2014). SO here is what I gather while doing this Lab: I added several IPs to putty in order to build information or to give information to the GUI that I am looking into.

...ENTERPRISE SETTING 2 A1 - Abstract Since 1999 wireless devices have become a necessity in enterprises. While increasing convenience, connectivity, and productivity, they also pose an unprecedented threat to network security guarding, which has literally taken to the airwaves. This paper will deal with vulnerabilities and risks regarding access points (APs) in a wireless network (WLAN) connecting to a wired local area network (LAN) in enterprises. Data for this paper will come from published academic papers, industry publications including white papers and surveys, and industry specialists. It will also include definitions of terms, policy and procedures that affect access points, and current practices regarding rogue APs. A case study will be presented for a fictional enterprise with multiple locations that has standard procedures, policies, and protocols in place, but recent events have questioned their ability to control access points with the discovery of rogue devices hidden in several office locations. Industry warnings about access points span the past thirteen years, and still new articles appear saying similar warnings, with only the solutions evolving with the technology. Suggested solutions will include security literacy regarding APs and their devices and their compliance; security audits to re-evaluate configurations of current hardware and software, inventory of current APs, wireless devices, ports, stations and their...

Preserving the compatibility of components is equally important as selecting the brand and quality. Each motherboard is not compatible with any graphics card, processor or memory, because there are different standards that are mostly defined by the manufacturer or are dictated by the development of technology. It is known that the power of data processing doubles every 18 months which fact in itself entail changes in the way of construction, materials, software and course standards of connectivity and compatibility of the hardware. As an example we can use the standard for connecting graphics cards. In 1997 the AGP (accelerated graphic port) was first introduced in his...
