By comparing the time out mechanism used in TCP to that used in a data link layer protocol, outline why it is necessary for the TCP timeout mechanism to implement an adaptive timeout duration
Answer:
When there are network flows within the wireless link that experience prolonged poor transmission it can impact on the network, leading to the stalling of the source while waiting for the arrival of ACKS, due to the filling of the TCP source congestion window. More time is lost as the source waits for a timeout to be caused by the expiration of the RTO timer which results in lower efficiency and network throughput by the TCP that requires an adaptive timeout duration to be implemented

Caleb Co. owns a machine that had cost $42,400 with accumulated depreciation of $18,400. Caleb exchanges the machine for a newer model that has a market value of $52,000. 1. Record the exchange assuming Caleb paid $30,000 cash and the exchange has commercial substance. 2. Record the exchange assuming Caleb paid $22,000 cash and the exchange has commercial substance.
Answer: See explanation
Explanation:
1. Record the exchange assuming Caleb paid $30,000 cash and the exchange has commercial substance.
Dr Machine (new) $52000
Dr Loss on exchange of asset $2000
Dr Accumulated Depreciation $18400
Cr Equipment (Old) $42400
Cr Cash $30000
Nite that loss was calculated as:
= Market value of new machine - (Book value if old machine - Depreciation) - Cash paid
= $52000 - ($42400 - $18400) - $30000
= $52000 - $24000 - $30000
= -$2000
2. Record the exchange assuming Caleb paid $22,000 cash and the exchange has commercial substance
Dr Machine (new) $46000
Dr Accumulated Depreciation $18400
Cr Equipment (Old) $42400
Cr Cash $22000
Note that the value of the new machine was calculated as:
= Original cost + Cash paid - Accumulated Depreciation
= $42000 + $22000 - $18400
= $46000

An operating system that allows a single user to work on two or more programs at the same time is what type of OS?
Answer:
Explanation:
The correct answer is none of these
An operating system that allows a single user to perform only one task at a time is called a Single-User Single-Tasking Operating System. Functions like printing a document, downloading images, etc., can be performed only one at a time. Examples include MS-DOS, Palm OS, etc.
Advantage: This operating system occupies less space in memory.
Disadvantage: It can perform only a single task at a time.
There are four types of operating systems −
Real-time operating system
Single-User/Single-Tasking operating system
Single-User/Multitasking operating system
Multi-User/Multitasking operating system
Real-time operating system is designed to run real-time applications. It can be both single- and multi-tasking. Examples include Abbasi, AMX RTOS, etc.
An operating system that allows a single user to perform more than one task at a time is called Single-User Multitasking Operating System. Examples include Microsoft Windows and Macintosh OS.
It is an operating system that permits several users to utilize the programs that are concurrently running on a single network server. The single network server is termed as "Terminal server". "Terminal client" is a software that supports user sessions. Examples include UNIX, MVS, etc.

Answer:
There are many benefits to be gained from network segmentation, of which security is one of the most important. Having a totally flat and open network is a major risk. Network segmentation improves security by limiting access to resources to specific groups of individuals within the organization and makes unauthorized access more difficult. In the event of a system compromise, an attacker or unauthorized individual would only have access to resources on the same subnet. If access to certain databases in the data center must be given to a third party, by segmenting the network you can easily limit the resources that can be accessed, it also provides greater security against internal threats.
Explanation:
The best method in network security to prevent intrusion are:
Understand and use OSI Model. Know the types of Network Devices. Know Network Defenses. Separate your Network. How can I improve security through network design?In the above case, the things to do is that one needs to focus on these areas for a a good network design. They are:
