...1. Explain the difference between operating system software, application software, and utility software. The difference between the 3 programs is that the operating system is the central control for all programs on a computer. The utility software is what keeps the operating system and application working normal without clutter or virus. Then the application software is what issued in the operating system to interact with the hardware to make the computer my user friendly. 2. Explain the concept of virtual memory and why it is needed. Virtual memory is the use of hard drive space for program data that is currently not in use. So that the program that does need the ram memory can use it without being hinder. 3. What would be a possible cause of disk “thrashing”? Disk thrashing could be possible if you have to mean application open at once. Which could over run your ram and your virtual memory? This could cause considerable damage to the hard drive do to the transferred data back and forth over it. 4. How is the Windows registry organized? Keys and sub keys 5. How would you change mouse parameters like double-click speed? To change the parameters you would first go to the start button on bottom left of your screen. From there find the control panel and click it. The go to the hardware and sound button were you will find the mouse button. Once you’re in mouse properties under the buttons tab you will see the double-click speed option to change it. 6. Why...

...1. Aaaa KEY TERMS: Transmission Control Protocol - is one of the core protocols of the Internet protocol suite (IP), and is so common that the entire suite is often called TCP/IP. TCP provides reliable, ordered, error-checked delivery of a stream of octets between programs running on computers connected to a local area network, intranet or the public Internet. It resides at the transport layer. User Datagram Protocol flow - is one of the core members of the Internet protocol suite (the set of network protocols used for the Internet). With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without prior communications to set up special transmission channels or data paths TCP Segment - consists of a segment header and a data section. The TCP header contains 10 mandatory fields, and an optional extension field UDP datagram - is one of the core members of the Internet protocol suite (the set of network protocols used for the Internet). With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without prior communications to set up special transmission channels or data paths. Source port – the port from which data is sent Destination port – the port to which data is to be sent Well-Known port number – example port 21 is usually the printer port Dynamic port - is an on-demand method of traversing a firewall/NAT...

...Assignment 1: Cable Testers Wire-Map Testers A wire-map tester transmits signals through each wire in a copper twisted-pair cable to determine if it is connected to the correct pin at each end. Wire-map testers detect transposed wires, opens, and shorts which are all problems that can render a cable useless. A wire-map tester consists of a remote unit that you attach to the far end of a connection and the battery-operated, handheld main unit that displays the results. Typically, the tester displays various codes to describe the type of faults it finds, so you know which part of the cable you messed up on or what else may be wrong with it. Tone Generators Tone generators are the simplest type of copper cable tester. A tone generator is made up of two parts, a tone generator and a probe. These are sometimes referred to as a fox and hound wire tracer. With a standard jack, you connect to the cable the unit that transmits a signal, or, with an alligator clip, you connect the unit to an individual wire. The other unit is an inductive amplifier, which is a pen like probe that emits an audible tone when touched to the other end of the conductor. Tone generators are most often used to locate a specific connection in a punch-down block. Using a tone generator is extremely time-consuming and it is nearly as prone to errors as the cable installation. Time-Domain Reflectometers A TDR is the primary tool used to determine the length of a copper cable and to locate the impedance variations...

...Legal Issues in Information Security 14 Executive Summery on Risk Mitigation Unit 9 ASSIGNMENT 1 ASSIGNMENT The protection of records that pertain to students is crucial in ensuring that their safety is not compromised. In doing so the following three things must be addressed in a very detailed and stringent manner. Confidentiality, Integrity, and Availability. These three facets of security are detrimental in the handling of information, whether it is student records or bank transaction records. C-I-A is a good practice when maintaining information and insuring the proper handling of said information. We will discuss here how C-I-A combined with FERPA will help to reduce mishandling and misuse of information, and how to deal with breach and loss as well. The confidentiality of information is vital to keep your students anonymity on line. Confidentiality means that only people with the right permissions can access and use the information. To ensure the confidentiality of the information, the location that it is stored will be secured by password protection. The principle of least privilege will be used as well in determining who has access to the information as well. Physically there will be endpoint encryption as well. All data that is stored in the servers will be encrypted as well. The integrity of the information is vital to ensure that any tampering of the information can be readily detected if it should occur. The integrity of the information is defined...

Monitor, mouse, keyboard, computer data storage, hard disk drive (HDD), system unit (graphic cards, sound cards, memory, motherboard and chips Describe how computer store data First, data is converted to simple numbers that are easy for a computer to store. Second, the numbers are recorded by hardware inside the computer. Third, the numbers are organized, moved to temporary storage and manipulated by programs, or software. Explain how programs work Computer programs work as a translator between operator and computer. This way the operator can tell the computer what to do. Difference among machine language, assembly language, and high-level languages? Machine language- is the bits that are used to control the cpu Assembly language- compilers High- level language- mathematical operations Differentiate between compilers and interpreters COMPILER- is a program that translates a high-level language program into a separate machine language program. INTERPRETER- is a program that both translates and executes the instructions in a high-level language program Identify the different types of software SHORT ANSWER 1.

...racticeBriefing Notes: Best Practices in Professional Development Introduction A firm interested in increasing its employees’ skills and competencies while deepening their employees’ commitment to the organization should c onsider three interventions: the nature of the job, formal training and the mentoring/co aching process. This paper on best practices outlines the issues firms fa ce in developing programs in these three areas and disc usses which practices, program designs or methods firms should take up in response to these issues. The Job Research in firms suggests that younger professionals are drawn to two different kinds of firms: the firm with a great reputation in the field, and the smaller, often less reputable, firms that offer younger people a broader range of opportunities. They usually favor the former when they regard their first or secon d job as a way station to a longer-term career in another company or setting and want to garner the “halo” effect of having worked at a great firm. This phenomenon o c curs in other professional services as well. For example, many consultants are happy to go to M cKinsey for their first five years of employment even though the prospect of becoming a partner and then a director are quite limited, and the work itself is extremely taxing. Many firms, however, cannot rely exclusively on the limited supply of skills within the firm to create opportunities for learning and growth. Therefore, these firms must...
