what are the characteristics of a computer system
Answer:
A computer system consists of various components and functions that work together to perform tasks and process information. The main characteristics of a computer system are as follows:
1) Hardware: The physical components of a computer system, such as the central processing unit (CPU), memory (RAM), storage devices (hard drives, solid-state drives), input devices (keyboard, mouse), output devices (monitor, printer), and other peripherals.
2) Software: The programs and instructions that run on a computer system. This includes the operating system, application software, and system utilities that enable users to interact with the hardware and perform specific tasks.
3) Data: Information or raw facts that are processed and stored by a computer system. Data can be in various forms, such as text, numbers, images, audio, and video.
4) Processing: The manipulation and transformation of data through computational operations performed by the CPU. This includes arithmetic and logical operations, data calculations, data transformations, and decision-making processes.
5) Storage: The ability to store and retain data for future use. This is achieved through various storage devices, such as hard disk drives (HDDs), solid-state drives (SSDs), and optical media (CDs, DVDs).
6) Input: The means by which data and instructions are entered into a computer system. This includes input devices like keyboards, mice, scanners, and microphones.
7) Output: The presentation or display of processed data or results to the user. This includes output devices like monitors, printers, speakers, and projectors.
8) Connectivity: The ability of a computer system to connect to networks and other devices to exchange data and communicate. This includes wired and wireless connections, such as Ethernet, Wi-Fi, Bluetooth, and USB.
9) User Interface: The interaction between the user and the computer system. This can be through a graphical user interface (GUI), command-line interface (CLI), or other forms of interaction that allow users to communicate with and control the computer system.
10) Reliability and Fault Tolerance: The ability of a computer system to perform consistently and reliably without failures or errors. Fault-tolerant systems incorporate measures to prevent or recover from failures and ensure system availability.
11) Scalability: The ability of a computer system to handle increasing workloads, accommodate growth, and adapt to changing requirements. This includes expanding hardware resources, optimizing software performance, and maintaining system efficiency as demands increase.
These characteristics collectively define a computer system and its capabilities, allowing it to process, store, and manipulate data to perform a wide range of tasks and functions.

Define a function named SortVector that takes a vector of integers as a parameter. Function SortVector() modifies the vector parameter by sorting the elements in descending order (highest to lowest). Then write a main program that reads a list of integers from input, stores the integers in a vector, calls SortVector(), and outputs the sorted vector. The first input integer indicates how many numbers are in the list.
Ex: If the input is:
5 10 4 39 12 2
the output is:
39,12,10,4,2,
For coding simplicity, follow every output value by a comma, including the last one.
Your program must define and call the following function:
void SortVector(vector & myVec)
Answer:
Here is an example implementation of the SortVector function and main program in C++
(Picture attached)
The SortVector function takes in a vector of integers by reference (indicated by the & symbol) and sorts the elements in descending order using the std::sort function from the algorithm library. The greater<int>() function is used as the comparison function to sort the elements in descending order.
In a new worksheet, you must start by typing in cell A1.

To maintain this security standard, you have decided to disable all the unused physical and virtual ports on your Huawei switches. Which one of the following commands will you use to bring your plan to action? a. shutdown b. switchport port-security c. port-security d. disable
To disable unused physical and virtual ports on Huawei switches, the command you would use is " shutdown"
How doe this work?The "shutdown" command is used to administratively disable a specific port on a switch.
By issuing this command on the unused ports, you effectively disable those ports, preventing any network traffic from passing through them.
This helps enhance security by closing off access to unused ports, reducing the potential attack surface and unauthorized access to the network.
Therefore, the correct command in this scenario would be "shutdown."

2. Identify two real-world examples of problems whose solutions do not scale well.
3. Identify one problem that is so complex that there is no computational solution to feasibly solve the problem in a reasonable amount of time.
1. Identify two real-world examples of problems whose solutions do scale well.
ANSWER; Real word examples of
problems whose solutions do scale well are;
- To find the smallest/ largest element in a list of data.
This is used when there is trial to find from a table the person that posseses the largest attribute.examples are salary and age.
Or it is also used when finding the highest score on a test, however,this is scalable as it can be done by both humans and machines according to the problem size but in the same fashion.
- Solving simple arithmetic equations.
Solving a simple arithmetic problem is one of an easily scaled problem, however,this depends on the number of operations and the variables present in the equation and which corresponds to daily life situations like adding, finding mean and counting.
2. Identify two real-world examples of problems whose solutions do not scale well.
Real word examples of problems which do not scale well are;
- The sorting of a large list of numbers do not scale well,this is because as the steps required increases as square or increases as more by the increase in size.
- Multiplication of matrices for various applications.example of this is like solving equations.
3. Identify one problem that is so complex that there is no computational solution to feasibly solve the problem in a reasonable amount of time.
Example of a problem that is not feasible computer-wise would be to find the optimal way or best to play the game of Chess. Here, it is possible to tell a good move but to tell the best move is computationally not possible.
