History of computers and IT careers development

  In today's digital age era, individuals and organizations are increasingly reliant on computer systems for communication, productivity, and data storage. With this reliance comes vulnerability to a variety of cyber threats. As outlined in CertMaster Learn tech+ ( TestOut Corp., 2024), information and system security are essential for protecting sensitive data, maintaining user privacy, and ensuring the integrity of operations. Without strong security measures, systems become susceptible to attacks that can lead to significant financial loss , reputational damage, and legal consequences. This paper explores the importance of network security, with a focus on two specific threats: phishing and malware/ ransomware . It also offers practical recommendations to mitigate these threats and safeguard information systems.   Phishing is a cyberattack technique in which attackers trick individuals into revealing confidential information such as usernames and passwords. Or fin...

Computers have become valuable in the healthcare industry, reshaping how patient care is delivered, how data is managed, and how healthcare professionals interact with information. From electronic health records to diagnosing ima ging systems, the integration of computer systems ensures accuracy, efficiency, and timely decision-making. In hospitals and clinics, computers are used for scheduling, billing, lab work, prescriptions, and accessing real-time patient information streamlining in both administrative and clinical tasks.   Computer literacy is crucial for healthcare employees because nearly every task requires interaction with a digital system. Physicians and nurses must navigate software effectively, tech nicians must operate complex diagnostic equipment, and administrators rely on database systems for managing patient flow and ins urance claims. A lack of computer proficiency can lead to medical errors, data breaches, and workflow bottlenecks, ultimately compromising...

  Part 1: Ping Activity   Using the Windows command prompt, I began by pining google. What showed was fou r packets were sent and all f our were received successfully , with 0% packets loss. The round-trip times ranged f rom 1 8 ms to 29 ms, as this is the result of a good and stable connection. Next, I pinged two international websites i n Canada and UK . For Canda I noticed a small er latency with my round-trio between 13 m s and only 14 ms. For UK , this ranged 1 2 ms to 13 ms similar to Canada but only receiving three packets with a 25% loss . Although this was different, there still was a less for both in ms in the roundtrips , but the lon ger round-trip times showed in the actual physical distance.   Part 2: Traceroute Activity   Running a tracert to google.com, I saw that the packets traveled through 30 hops. Each hop had almost every hop had three round-trip measurements, and the average hop was low, staying under 25ms including the final ho...
