The server should be able to block unauthorized access, a good firewall but still, enable those authorized to have an access. However, there should be security on vulnerable parts of the system that may lead to corruption and easy access to data thieves.

Answer:
File transfer protocol (FTP)
Explanation:
An information can be defined as an organized data which typically sent from a sender to a receiver. When a data is decoded or processed by its recipient it is known as information.
Generally, there are several channels or medium through which an information can be transmitted from the sender to a receiver and vice-versa. One of the widely used media is the internet, a global system of interconnected computer networks.
There's a standard framework for the transmission of informations on the internet, it is known as the internet protocol suite or Transmission Control Protocol and Internet Protocol (TCP/IP) model. One of the very basic rule of the TCP/IP protocol for the transmission of information is that, informations are subdivided or broken down at the transport later, into small chunks called packets rather than as a whole.
The three (3) main types of TCP/IP protocol are;
I. HTTP.
II. HTTPS.
III. FTP.
File transfer protocol (FTP) is used between two or more computers. One computer sends data to or receives data from another computer directly through the use of network port 20 and 21.
Restrictive policy is a kind of policy calls for a firewall to contradict all traffic by default. The first rule denies all traffic on any service and using any port. To permit a specific type of traffic, a new rule must be placed ahead of the deny all rule. A firewall should enforce the overall policy recognized by the network administrator. Enforcement is controlled mainly over setting up packet filtering rules which is a rule base comprises a set of these rules.
Answer:
correct option is D i.e. 20
Explanation:
Given data:
Parallelizable portion is given as 95%
so remaining will be serial portion i.e. 5%
we know that, for infinite number of cpus, maximum speed is calculated as
where f denote serial portion = 5% = 0.05
v = 20
hence so for serial portion of 5%, maximum speed is 20
correct option is D i.e. 20
