Answer:

Explanation:

A computer virus is a form of malicious software that piggybacks onto legitimate application code in order to spread and reproduce itself.

Like other types of malware, a virus is deployed by attackers to damage or take control of a computer. Its name comes from the method by which it infects its targets. A biological virus like HIV or the flu cannot reproduce on its own; it needs to hijack a cell to do that work for it, wreaking havoc on the infected organism in the process. Similarly, a computer virus isn't itself a standalone program. It's a code snippet that inserts itself into some other application. When that application runs, it executes the virus code, with results that range from the irritating to the disastrous.

Computer virus symptoms

How can you tell if a virus has slipped past your defenses? With some exceptions, like ransomware, viruses are not keen to alert you that they've compromised your computer. Just as a biological virus wants to keep its host alive so it can continue to use it as a vehicle to reproduce and spread, so too does a computer virus attempt to do its damage in the background while your computer still limps along. But there are ways to tell that you've been infected. Norton has a good list; symptoms include:

Unusually slow performance

Frequent crashes

Unknown or unfamiliar programs that start up when you turn on your computer

Mass emails being sent from your email account

Changes to your homepage or passwords

Answer:

The NIC is disabled in CMOS

Explanation:

CMOS refers to the Complementary Metal Oxide Semiconductor.  It is a technology that is used to generated integrated circuits.

It can be found in various types like microprocessors, batteries, etc

While on the other hand the NIC refers to the network interface controller in which the component of the computer hardware has connected the computer to its network. It can be done via wired and wireless.

Since in the given situation, it is mentioned that Ellen is not able to access the internet through wireless NIC neither it is visible in network connections nor it is shown in device manager so first she assumes that is nic is disabled in CMOS

and the same is to be considered

List at least five tasks a layer performs. Could one (or more) of these tasks could be performed by multiple layers?
ludmilkaskok [199]

Answer:

Transport layer:

- data packets are segment to smaller chunks.

- gives sequence number to segment.

- identifies the source and destination port number.

- initiates data transmission between nodes.

- rearrange and identifies the application, the transmitted data is meant for.

Explanation:

The transport layer is the fourth layer in the OSI network model. Protocols like TCP and UDP are found in this layer. It segment data packets and for a connection oriented protocol like TCP, it creates an established session between source and destination host (the session layer can also do this, but it is more defined in the transport layer).

The network and data-link layer can also transmit data packets.

SVETLANKA909090 [29]

Answer:

Replace /* Your solution goes here */ with the following expression

accelGravity = (G * M) / (distCenter *distCenter );

Explanation:

Required

Complete the code

The equivalent expression of (G * M) / (d^2) is:

(G * M) / (distCenter *distCenter );

The expression must be stored in accelGravity.

So, we have:

accelGravity = (G * M) / (distCenter *distCenter );
