Answer and Explanation:
LAN transmission and reception handles the given bellow details
- LAN adds hardware address and use for error detection codes
- Use DMA to copy frame data directly from main memory
- it follows access rule then transmission is in progress
- it also check the address where data is sent on incoming frames
if the destination address completely match with location address a copy of the frame is passed to the computer
in LAN system a single pocket is sent to the one or more nodes
Continuing advances in technology and automation will be eliminating repetitive work in the offices of the future.
Computer technology has had a tremendous impact upon workers. In some instances, the introduction of computers has improved member working conditions, but, in others, new technology has produced several detrimental effects.
Explanation:
- One of the key trends to emerge was that automation, smart machines and artificial intelligence will conduct repetitive work, replacing the need for people to complete these tasks.
- Instead of worrying about job losses, executives should be helping to reduce jobs in which AI and machine learning take over boring tasks, while humans spend more time with higher-level tasks.
Here are three ways eliminating repetitive work can boost productivity:
- <u> Reduce Dependency on Email and Spreadsheets :</u> Automation tools such as mobile applications, customized portals and project management tools eliminate the time spent checking and responding to emails and updating spreadsheets to reflect work progress. With automated tools, managers and their teams can post progress or project information on an integrated mobile app.
- <u>Reduce Mistakes and Injuries </u>: The possibility of human errors, which take more time to correct, is virtually eliminated when tasks are automated. Leaving the monotonous tasks to machines reduces the chance of injuries and allows workers to keep working on more strategic tasks.
- <u> Free Employees Time for High-Level Skills</u> : Many of the employees who spend their time undertaking repetitive tasks could actually be better utilized on more complex tasks.
There are a variety of illnesses that may be caused by repetitive computer work :
-
Tendonitis : pain and swelling of tendons at the junction between the tendon and its muscle;
- Epicondylitis: pain and swelling where the tendons and bone join around the elbow joint, etc
Inputs are the contols that let you interact with an operating system.
Answer:
Bill is building a project network that involves testing a prototype. he must design the prototype (activity 1), build the prototype (activity 2), and test the prototype (activity 3). activity 1 is the predecessor for activity 2 and activity 2 is the predecessor for activity 3. if the prototype fails testing, bill must redesign the prototype; therefore, activity 3 is a predecessor for activity 1. this is an example of
b. looping
Explanation:
- The given example is of looping because each activity is leading to another activity on the completion of some conditions.
- The answer a is not valid as it is not just an example of conditional statements rather it is a loop which will keep moving until unless reached a situation to end it.
- The option c, d an e are not right options for the given example.
