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.

What encryption method is used by WPA for wireless networks?

azamat

<span>The WPA protocol implements much of the IEEE 802.11i standard. Specifically, the Temporal Key Integrity Protocol (TKIP) was adopted for WPA. WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change.</span>

i have a bag of trail mix . one half of the bag is peanuts. 1/4 of the bag is chocolate candies , and 1/4 of the bag is died fru

Lelu [443]

In our bag, 1/2 is peanuts, 1/4 is chocolate and 1/4 is dried fruit.

The likelihood of drawing a chocolate therefore is 1/4.

The likelihood of drawing a peanut is 1/2 and the likelihood of drawing a dried fruit is 1/4.

Thus, D is the correct answer because the 1/4 likelihood of drawing a chocolate is less than the 1/2 chance of drawing a peanut.

Consider an error-free 64 kbps satellite channel used to send 512 byte data frames in one direction, with very short acknowledge

Vladimir [108]

Answer:

The answer is "2".

Explanation:

In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:

Given values:

Bandwidth = 64 kbps

Data frames = 512 bytes

Propagation Time (tp ) =270 ms

Change Bandwidth kbps to bps:

1 kb= 1024 bytes

calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps

1 bytes = 8 bits

512 bytes = 512 × 8 = 4096 bits

Frame length = 4096 bits

Formula

Transmission time (Tt) = Frame length /Bandwidth

Window size = 1+2a

where a = Propagation time/Transmission time

Calculate Transmission time:

Transmission time (Tt) = 4096 / 65536

Transmission time (Tt)= 625 m.sec

Calculate Window size:

Window size = 1+2(270/625)

Window size = 1+2(0.432)

Window size = 1+0.864

Window size = 1.864

Window size = 2

Volgvan

Answer:

System unit.

Explanation:

Some people use the term system unit to refer to the case that contains and protects the motherboard, internal hard drive, memory, and other electronic components of the computer from damage.

A system unit also referred to as chassis or tower can be defined as a hardware case that is typically used as a protective case for the main component or primary devices such as power supply, random access memory (RAM), graphics card, CD-ROM drive, Harddisk drive, motherboard, internal cables, central processing unit (CPU) that makes up a computer system.

Basically, the main purpose of a system unit is to properly house the main components of a computer, serve as an electrical insulator and to prevent them from any form of damage.
