How To Answer “Tell Me Something That Is Not On Your Resume” In An Interview
  1. Can you explain the difference between computer hardware and software?

Hardware refers to the physical components of a computer system, such as the motherboard, CPU, RAM, and storage devices. Software, on the other hand, refers to the programs and operating systems that run on the computer and control its functions.

  1. How do you troubleshoot a computer that won’t turn on?

First, I would check to make sure that the computer is properly plugged in and that the power outlet is working. Then, I would check the power supply and ensure that it’s functioning properly. If the power supply is the issue, I would replace it. If the problem persists, I would then check the connections and cables to ensure they are properly connected.

  1. How do you optimize the performance of a computer?

There are several ways to optimize the performance of a computer. One way is to ensure that the computer has enough memory and storage. Another way is to regularly perform maintenance tasks, such as cleaning up the hard drive, removing unnecessary files and programs, and updating the operating system. Additionally, I would also use performance monitoring tools to identify and resolve bottlenecks in the system.

  1. Can you explain how a computer processes data?

A computer processes data by using its central processing unit (CPU) to execute instructions. The CPU retrieves instructions from memory and uses its arithmetic and logic unit (ALU) to perform calculations and logical operations on the data. The results are then stored in memory for future use.

  1. How do you protect a computer from malware?

One way to protect a computer from malware is to install and regularly update anti-virus software. Additionally, it’s important to be cautious when clicking on links or downloading files from unknown sources and to keep your computer and software updated. I also recommend to use a firewall to block unauthorised access to your computer and to use a browser extension like uBlock Origin to block ads and pop-ups.

  1. Can you explain how a computer network works?

A computer network is a group of interconnected computers and devices that can share resources and exchange information. Computer networks use a variety of protocols to transmit data and can be connected through wired or wireless connections. The most common types of computer networks are LAN (Local Area Network), WAN (Wide Area Network) and the Internet.

  1. Can you explain the difference between a 32-bit and 64-bit operating system?

A 32-bit operating system can handle data in 32-bit chunks, while a 64-bit operating system can handle data in 64-bit chunks. 64-bit operating systems can process more data at once, allowing for faster performance. Additionally, 64-bit operating systems can access more memory than 32-bit operating systems.

  1. Can you explain how data is stored on a computer?

Data is stored on a computer’s hard drive or solid-state drive using a process called magnetic or electrical polarization. Data is stored on the drive in the form of 0s and 1s, called bits. The bits are grouped together to form bytes, which are the basic unit of data storage. The bytes are organized into blocks, which are grouped together to form a file.

  1. Can you explain how encryption works?

Encryption is the process of converting plaintext into ciphertext to protect it from unauthorized access. This is done by using an encryption algorithm and a key. The encryption algorithm takes the plaintext and the key as input and produces ciphertext as output. To decrypt the ciphertext, the recipient uses the key and the same encryption algorithm to convert the ciphertext back into plaintext. This process ensures that only authorized individuals with the correct key can access the original information.

  1. Can you explain the difference between a static and dynamic IP address?

A static IP address is a fixed address assigned to a device, while a dynamic IP address is an address that can change. Static IP addresses are typically used for servers or other devices that need to be accessed remotely, while dynamic IP addresses are used for devices that do not need to be accessed remotely, such as home computers. Dynamic IP addresses are assigned by a DHCP server, which automatically assigns an available IP address to a device when it connects to a network.
