The above question has multiple choices as below
A. Data links
B. The post office
C. Driving a car
D. A train
The answer is (B) The Post Office.
In layman’s terms, transport layer is similar to the post office functions of delivering parcels and letters at the agreed delivery deadlines. It also notices any dropped info and re-transmits it.
Just like the post office, the transport layer directs messages and information between specific end users. If by mistake you write a letter to the wrong person, the letter will be returned and the postal employee will stamp it as address unknown.
Answer:
You should install a personal firewall, a program that protects your computer from unauthorized access by blocking certain types of communications.
Explanation:
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet.
Answer:
Software requirement specification
Explanation:
requirement specification is the first step before proceeding with any project.
we should validate our output at all phases with software requirement specification
Answer:
algorithm.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
Furthermore, the processing symbols and their functions used in developing an algorithm are oval (start or stop), diamond (decision-making), circle (on-page connector), parallelogram (input and output), rectangle (calculation), arrow (flow or direction) and pentagon (off-page connector).
Some of the characteristics of an algorithm include the following;
I. An algorithm can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. An algorithm can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
In conclusion, an algorithm is a sequence of precise instructions which result in a solution for solving problems using a computer system.
