Hackers were harmful to computer

1. Artificial intelligence able to be a better predict traffic as it collects and analyzes data in real time,

2. some of network managers were better prepared for big events such as the World cup, Olympics, Valentine’s Day, which often put on the Internet under pressure.

3. Now the networks were monitored by algorithm that enables for anomalous build-ups of traffic and activity which may be the result of nasty activities such as (DDos) Distributed Denial-of-Service attacks and attempted hacks.

4. This Artificial Network powering algorithms will become most intelligent; it might find faster and reliable methods of anticipating threats and cleaning networks.

In mobile network, land areas for network coverage was distributed as cells

Cloud Storage:

Cloud Storage is without any Just a storage of data on online. It can be access from different area geographical limits

Cloud Computing:

Cloud Computing is based on Internet computing, to share resources, software and information.

Money saving:

Using the computer networking, it’s important financial aspect for organization because it saves money. It reduces the paper work, man power and save the time.

Features of Mobile Networks:

1. Less consumption of power is used by mobile devices comparing with a single mitter or satellite often cell towers were nearer.

2. Huge capacity than a large mitter, at single frequency can be used for different or many links as long as they are in different in cells.

3. Covering large area than a single mitter, we can add more towers indefinitely and cannot be limited by any horizon limits.

First In 1969, four nodes of ARPANET were connected between four universities namely the university of California at Los Angeles, at Santa Barbara, the Stanford Research Institute and the university of Utah using the 50 Kbit/s circuits.

Packet -switched networks was the theoretical work to model was performed by Leonard Kleinrock, ARPANET was which underpinned the development of it and his theoretical work on hierarchical routing in late 1970 s with his student Farouk Kamoun remains critical to the operation of the Internet today.

Networks at home were connected in two ways they are:

1. Wired network

2. Wireless network A Wired network system connected with network cable.

For example speakers, CCTV, printers, outdoors, and scanners etc., with cables.

A Wireless network is connecting devices like tablets(tab), indoor cameras and E-readers, etc., without cables (WiFi).

19^th Electron of copper lies in 4s orbital. 

So, n = 4, l= 0, m = 0, s = +1/2

This happens because the tile is better heat conductor than wood. The heat conducted from our foot to the wood is not conducted away rapidly. So, the wood quickly heats up on its surface to the temperature of our foot. But the tile conducts the heat away rapidly and thus can take more heat from our foot, so its surface temperature drops. 

A moving material particle like electron, proton etc., having mass m and velocity v is associated with wavelength \(\lambda\) related to:

\(\lambda\) = \(\frac{h}{mv}\) = \(\frac{h}{p}\)

Where p stands for momentum of the particle and h is Planck's constant. This relation is known as de-Broglie equation.

1.Reasons: Carbon forms a large number of compounds. Two properties of carbon that help it to form so many compounds is:
Catenation (The ability of carbon to combine with other atoms of carbon).
It forms strong covalent bonds with various elements like oxygen, nitrogen, chlorine, bromine, etc.

2.Blackening (deposition of unburnt carbon particles) of the cooking vessels show that incomplete combustion of the gas is taking place. As combustion is not taking place, the maximum amount of energy that can be obtained from the fuel cannot be obtained i.e., gas is being wasted. 

Limited supply of air results in the incomplete combustion of saturated hydrocarbons. Hence, the air holes of a gas burner have to be adjusted, so that, a sufficiently oxygen-rich mixture is burnt and a clean blue flame is obtained.

In ‘A Sunny Morning’, according to Petra, the guard, with whom she used to chat, belongs to the park.

Horizontal rows of elements in the modern periodic table are called periods.

Vertical columns of elements in the modern periodic table are called groups.

Elements present in groups 1 and 2 on the left side and 13 to 17 on the right side of the modern periodic table with one outermost shell incomplete are called normal elements.

Elements present in groups 3 to 12 in the middle of the modern periodic table with two incomplete outermost shells are called transition elements.

For an isolated atom, the distance between the centre of the atom and the outermost shell is called its atomic radius.

Atoms of the same element having different atomic masses but same atomic number are called isotopes.

A set of 14 elements with atomic numbers 90 to 103 (Th to Lr) having similar chemical properties are called actinides.

Margie wrote, “Today Tommy found a real book!”

A set of 14 elements with atomic numbers 58 to 71 (Ce to Lu) having similar chemical properties are called lanthanides.

Elements placed at the bottom of the modern periodic table with three incomplete outermost shells are called inner transition elements.

No, she had never seen a book before.

Elements which show the properties of both metals and non-metals are called as metalloids.

Correct answer is (A) inert

Mendeleev’s Periodic law states that “The physical and chemical properties of elements are a periodic function of their atomic masses.”

Newlands’ periodic table did not include inert gases

Demerits of Newlands’ Octaves: 

i. Out of the 56 elements known, Newlands arranged the elements only upto calcium. 

ii. After calcium, every eighth element did not possess similar properties to those of the first. 

iii. In order to fit the existing elements, Newlands placed two elements in the same position which differed in their properties.

Newlands’ Octaves law states that “When the elements are arranged in an increasing order of their atomic masses, the properties of the eighth element are similar to the first.”

In Newlands’ octaves, after calcium every eighth element did not possess properties similar to that of the first.

The correct answer is True

Side of square park = 60 m

Perimeter of square park = 4 x side

= 4 x 60 = 240 m

Distance covered by Radha everyday

= No. of rounds x Perimeter of park

= 2 x 240 = 480 m

Fraction 7/25 is equal to the decimal number 0.28

The correct answer is (A) 119/500

Area of circle = πr² 

But area is given to be 25π sq.cm.

∴ 64π = πr² 

∴ r² = 64 

∴ r = 8 cm

Perimeter of sector = 2r + S 

But perimeter is given to be 20 cm.

∴ 56 = 2(5) + S 

∴ 56 = 16 + S 

∴ S = 40 cm

Area of sector = 1/2 x r x S

= 1/2 x 8 x 40

= 160sq.cm.

The correct answer is True
