Explanation:I don't say you have to mark my ans as brainliest but if you think it has really helped you plz don't forget to thank me..
1. A repeater amplifies and extends signals, while a hub is a multi-port device that broadcasts data to all connected devices, creating a shared collision domain.
2. A bridge connects network segments at the data link layer and forwards packets based on MAC addresses, while a router connects networks at the network layer and forwards packets based on IP addresses.
1. Difference between a Repeater and a Hub:
Repeater:
Operates at the physical layer (Layer 1) of the network.
Regenerates and amplifies network signals to extend their reach and overcome signal degradation.
Does not inspect or manage network traffic.
All devices connected to a repeater share the same collision domain.
Transparent to network protocols and does not interpret data.
Hub:
Operates at the physical layer (Layer 1) of the network.
Multi-port device that broadcasts incoming data to all connected devices.
Creates a single collision domain, causing devices to contend for network bandwidth.
Lacks intelligent traffic management and filtering capabilities.
Limited in terms of network performance and scalability due to shared bandwidth
2. Difference between a Bridge and a Router:
Bridge:
Operates at the data link layer (Layer 2) of the network.
Connects and joins separate network segments or LANs to form a single logical network.
Forwards data packets based on MAC addresses.
Builds and maintains a table (MAC table) of MAC addresses and associated network interfaces.
Bridges are commonly used to reduce network congestion and improve performance within smaller networks.
Does not perform IP address-based routing.
Router:
Operates at the network layer (Layer 3) of the network.
Connects multiple networks and routes data packets between them based on IP addresses.
Determines the best path for packet delivery using routing tables and protocols (e.g., RIP, OSPF, BGP).
Performs network address translation (NAT) and offers features like firewall and network traffic management.
Enables communication between networks with different IP address schemes.

John recently worked on a project about various programming languages. He learned that though procedural language programs are useful, they have disadvantages too. What is a disadvantage of programs written in procedural languages? A. Programs do not represent data complexity. B. Programs take more time to execute. C. Programs are prone to security threats. D. Programs do not interface with multiple platforms.
Answer:
Option A Programs do not represent data complexity.
Explanation:
In procedural languages like C, it doesn't support object oriented design that could encapsulate data in an object that entails a set of relevant attributes and methods which can represent an entity in real life better. This means the procedural language is limited by creating an object-like data structure that can represent data complexity. The procedural language only support the running a program by following a set of instructions in order.

Tech A says that most lug nuts and studs are right-hand threaded, which means they tighten when turned clockwise. Tech B says that some lug nuts and studs are left-handed, which means they tighten when turned counterclockwise.
This question is incomplete.
Complete Question
Tech A says that most lug nuts and studs are right-hand threaded, which means they tighten when turned clockwise. Tech B says that some lug nuts and studs are left-handed, which means they tighten when turned counterclockwise. Who is correct?
a) Tech A
b) Tech B
c) Both Tech A and B
d) Neither Tech A not B
Answer:
c) Both Tech A and B
Explanation:
The Wheels of cars or vehicles are attached or fastened to the car rims using what we call lug nuts and wheel studs. The lug nuts attached or torqued properly on the wheel studs in order to ensure that the wheels of the car are well secured , attached and firm.
We have different types of lug nuts and wheel studs. The differences is based on the threading that it found on both the lug nut and wheel studs.
We have:
a) The right handed threaded lug nuts and studs(wheel studs)
b) The left handed threaded lug nuts and studs(wheel studs).
The right handed threaded lug nuts and studs are tightened when they are turned in the clockwise direction while left handed threaded lug nuts and studs are tightened in the anticlockwise or counterclockwise direction.
It is important to note that no matter the kind of lug nuts and studs(whether right handed threaded or left handed threaded) used to fastened wheels to car rims, it is essential that they are well fastened and torqued to car to prevent them from loosening up.
For the question above, both Tech A and Tech B are correct. Therefore , Option C is the correct option.

What size hard disc would you recommend if I want to buy a computer for practising PowerPoint presentations at home and why do you recommend such a size
Answer:
PowerPoint is computer program which uses graphics with an in-build templates that could be used or customized, for creating slides for presentations. It has so many versions which for example include PowerPoint 2013, PowerPoint 2016. It doesn't require so much hard disc space, unlike some programming software and gaming applications. For Power point 2013 version, it can run on a computer with a 1 GHz processor (speed of the computer), operating system of windows 7 and above, a 3 GB disk space and a 2GB RAM of internal space. While if a 2016 power point version is to be used, a processor speed of 1 GHz will do, a minimum of 1 GB ram equivalent to 32-bit, hard disk space of 3 GB, then a minimum of windows 8. All these parameters mentioned above are important to ensure a smooth running of the computer program. As a lesser processor might result to the slow running of the computer program.
Explanation:
Hard disc is storage device in a computer, It has bigger data capacity than floppy disks. It exists in different storage capacity measured in kilobytes, gigabytes and terabytes.

• Audience
• Goals
Explanation:
Trevor works for many different clients and creates a wide variety of business publications. The two factors in the list below have the most influence over his layout designs are:
a) Audience
From the above question,we can see that Trevor creates different publications for different clients. This is because, the taste, wants or desires of each clients varies. It is not the same. Therefore, the layout of his publication is influence by the target audience that the publication is meant for.
For example, a client may want a publication with big fonts because the target audience who would be reading the publication are elderly people.
Another clients may want his publication designed with smaller fonts and a unique font style.
It is Trevor's duty to make sure that he caters to the needs his client's target audience by satisfying their desires, however different they may be.

The goals of the publication is one of the things that can influence the layout design of Trevor's publication. Let's take for example, a client is creating a publication to reach the teen society, probably a publication on pop music or fashion, this is the goal. Trevor would have to create the publication such that it attracts teens. The layout of the publication would have to come in catchy colours, interesting fonts, musical symbols that would catch the eye of teens and make them want to read such publication.

Discuss the evolution of file system data processing and how it is helpful to understanding of the data access limitations that databases attempt to over come
Answer:
in times before the use of computers, technologist invented computers to function on disk operating systems, each computer was built to run a single, proprietary application, which had complete and exclusive control of the entire machine. the introduction and use of computer systems that can simply run more than one application required a mechanism to ensure that applications did not write over each other's data. developers of Application addressed this problem by adopting a single standard for distinguishing disk sectors in use from those that were free by marking them accordingly.With the introduction of a file system, applications do not have any business with the physical storage medium
The evolution of the file system gave a single level of indirection between applications and the disk the file systems originated out of the need for multiple applications to share the same storage medium. the evolution has lead to the ckean removal of data redundancy, Ease of maintenance of database,Reduced storage costs,increase in Data integrity and privacy.
