Fast recovery is used in instances where data needs to be recovered quickly from a backup. Fast recovery can be used in instances where data is lost or corrupted, or in instances where the system needs to be restored to a previous state.
What is fast recovery?
Fast Recovery is now TCP's final advancement. Every time network congestion is identified, the congestion window is reduced to 1 by using solely Fast Retransmit. As a result, reaching high link utilisation again takes some time. Fast Recovery, on the other hand, solves this issue by doing away with the slow-start period. Slow-start will specifically only be used at the start of a connection and once an RTO time has expired. The lack of slow-start after receiving three duplicate ACKs is due to the fact that triple ACKs inform the transmitting side of more than just packet loss. The dup ACK informs the sending side that packet has been missed by the network since the receiving side can only generate one if it gets an out-of-order packet.

<span>c. assembly language
Let's look at the 4 choices and see why they work, or don't work for this question.
a. extensible markup language - Otherwise known as XML, this is a markup language that's designed to allow data to be shared between different systems in a portable manner. HTML is a subset of XML. Definitely not machine dependent, so this is the wrong answer.
b. structure query language - Otherwise known as SQL, this is a language used in defining queries to a remote or local database. It's intended so that the actual implementation of the database is unknown to the user and allows the user to write database queries in a portable fashion. Also not machine dependent, so this is the wrong answer.
c. assembly language - This is a low level language specific to the CPU architecture. A program written for the x86 platform won't run on a 680x0 based machine and visa versa. A program written for SPARC won't run on an x86 machine. Assembly language programs tend to directly manipulate the hardware of the computer directly and are very machine dependent. This is the correct answer.
d. high-level language - Some example languages would be C, C++, Basic, Algol, Pascal, etc. High level languages were developed so that programs could be easily moved over to other computers as newer more powerful computers because available. They also abstract details about the hardware so that the programmers don't need to know every single detail about the underlying computer. Purpose is to allow programs to be portable across multiple platforms with minimal to no effort. Not the correct answer.</span>
It allows power boats to have stability while cruising. The cathedral hull is like a trimaran in terehat it has one main and two side hulls stuck together so that has a somewhat square to rectangular shape and therefore exhibits greater stability than a single hulled boat. It became more popular with the advent of fibreglass boats in the 1960's and '70s.
As an IT technician, I need to understand how to end processes on the process tab of the task manager. Most techies are interested in this tab to determine what process is consuming what resources. Bryce’s computer has a suspicious application that has 90% CPU consumption, and this, as a result, will affect the computer.
- First on the list of things that I am required to identify the actual application that is causing the surge on the CPU column,
- Next I should be able to right click on it, and select End process on Windows 7 or End task on Windows 8 and later. Carrying out this task will noticeably stabilize Bryce’s computer.
- Finally, I will try to find out whether this application is causing harm to the computer in any possible way. If it is, then I should consider uninstalling it. If it not, I should be able to request Bryce to do an upgrade on his PC in order to handle the application more effectively.
