Routing in OSI Network Architecture

Answer: B. Data link layer

Explanation:

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven different layers. The routing process, which involves the selection of the best path for data packets to travel from the source to the destination, is primarily performed by the network layer in the OSI model. However, the data link layer also plays a role in routing by facilitating the transmission of data between directly connected nodes or devices. Here's a breakdown of the routing process in the OSI model:

1. Network Layer:

• The network layer is responsible for logical addressing, routing, and path determination.


• It receives data from the transport layer and adds network layer headers to create packets.


• It determines the best path for packet transmission based on the destination address and network conditions.


• It uses routing protocols (such as OSPF, RIP, BGP) to exchange routing information and build routing tables.


• It forwards packets to the next hop or the next network based on the routing table.

2. Data Link Layer:

• The data link layer provides reliable point-to-point communication between directly connected nodes.


• It encapsulates the network layer packets into data frames and adds data link layer headers and trailers.


• It performs error detection and correction using techniques like CRC (Cyclic Redundancy Check).


• It controls the flow of data between devices to avoid congestion.


• It uses MAC (Media Access Control) addresses to identify devices on the same network.


• It performs local network routing by forwarding data frames to the appropriate device based on MAC addresses.

While the primary responsibility of routing lies with the network layer, the data link layer contributes to the routing process by facilitating communication between directly connected devices. Therefore, in the OSI network architecture, routing is performed by both the network layer and the data link layer.

To determine which statements are true about a laser printer, we need to compare it with an inkjet printer and a dot matrix printer.
Comparison between a laser printer and an inkjet printer:
- (i) A laser printer gives a better quality printout compared to an inkjet printer. Laser printers use a toner cartridge and a laser beam to produce high-resolution prints with sharp text and graphics.
- (ii) A laser printer is less expensive than an inkjet printer. Laser printers are generally more expensive upfront, but they have lower operating costs compared to inkjet printers. Inkjet printers require frequent cartridge replacements, which can add up over time.
Comparison between a laser printer and a dot matrix printer:
- (iii) A laser printer is more expensive than a dot matrix printer. Dot matrix printers are typically the cheapest type of printer available, but they have lower print quality and slower printing speed compared to laser printers.
- (iv) A laser printer gives a better quality printout compared to a dot matrix printer. Laser printers produce high-resolution prints with sharp text and graphics, while dot matrix printers use a matrix of pins to strike an inked ribbon, resulting in lower quality prints.
Therefore, the correct answer is d. i, iii, iv, as all of these statements are true about a laser printer.

A dot matrix printer is a type of printer that uses a matrix of small pins to create characters or images on paper. Let's analyze each statement to determine the correct answer:
i) Prints an entire line at a time: This statement is incorrect. A dot matrix printer prints one character at a time by striking an ink-soaked ribbon against the paper. It does not print an entire line at a time.
ii) Is a non-impact printer: This statement is incorrect. A dot matrix printer is an impact printer because it uses physical force to create the characters. The pins strike the ribbon, which transfers ink to the paper, resulting in the printed output.
iii) Allows multiple copies to be taken at a time: This statement is correct. Dot matrix printers have the ability to create multiple copies simultaneously. This is achieved by using carbon paper or carbonless paper, which allows the impact of the pins to transfer the image to multiple layers of paper.
iv) Prints one character at a time: This statement is correct. Dot matrix printers operate by individually striking pins against an ink-soaked ribbon to create characters. Each pin represents one dot, and the combination of dots forms the characters or images on the paper.
Based on the analysis above, the correct answer is C: iii and iv. A dot matrix printer allows multiple copies to be taken at a time and prints one character at a time.

Term for changing the direction of a clip art image:
The term used when a clip art image changes the direction it faces is called flipping or mirroring.
Explanation:
When a clip art image changes its direction, it means that it is being reflected horizontally or vertically. This can be done to create a mirror image of the original clip art or to change its orientation.
- Flip: Flipping is the process of changing the direction of a clip art image. It can be done horizontally (left to right) or vertically (top to bottom).
- Rotate: Rotation refers to changing the angle or orientation of a clip art image. It involves rotating the image by a certain degree around a fixed point.
- Group: Grouping is a different concept and not related to changing the direction of a clip art image. Grouping refers to combining multiple objects or elements together to form a single unit.
In this case, the correct answer is option D: Both (a) and (b) - which means the term used is "flip" and it is also known as "group" when combined with other clip art images.
Summary:
The term used when a clip art image changes the direction it faces is flipping or mirroring. This allows for horizontal or vertical reflection of the image. The term "rotate" refers to changing the angle or orientation of the image, while "group" refers to combining multiple clip art images together.
