Startek Technical Support Executive Interview Questions, Process, and Tips

The components of a CPU include the arithmetic logic unit (ALU), control unit, registers, cache memory, and buses.

• Arithmetic Logic Unit (ALU) performs arithmetic and logical operations

• Control Unit manages the execution of instructions

• Registers store data and instructions temporarily

• Cache Memory stores frequently accessed data for faster retrieval

• Buses connect the CPU to other components of the computer system

RAM is volatile memory used for temporary storage while ROM is non-volatile memory used for permanent storage.

• RAM stands for Random Access Memory and is used for temporary storage of data and programs while the computer is running.

• ROM stands for Read-Only Memory and is used for permanent storage of data and programs that cannot be changed.

• RAM is volatile memory, meaning it loses its contents when the power is turned of...read more

BIOS stands for Basic Input/Output System. It is a firmware that initializes hardware during the boot process.

• BIOS is responsible for performing a Power-On Self Test (POST) to check if all hardware components are functioning properly.

• It also provides a set of low-level software routines that allow the operating system to communicate with hardware devices.

• BIOS settings can be accessed and modified through a setup utilit...read more

The CPU consists of three main components: the control unit, the arithmetic logic unit, and the cache.

• The control unit manages the flow of data and instructions within the CPU.

• The arithmetic logic unit performs mathematical and logical operations.

• The cache is a small amount of memory used to store frequently accessed data.

• Other components include registers, buses, and clock generators.

• Examples of CPUs include Intel Cor

To solve system hang-up issue, try restarting the system, checking for malware, updating drivers, and freeing up disk space.

• Restart the system and check if the issue persists

• Check for malware and viruses using antivirus software

• Update drivers for hardware components

• Free up disk space by deleting unnecessary files and programs

RAM is required in a system to store and access data quickly.

• RAM stands for Random Access Memory

• It is a volatile memory that stores data temporarily

• The CPU can access data from RAM much faster than from a hard drive

• The amount of RAM affects the system's performance

• Multitasking is possible due to RAM

• Examples of RAM include DDR3, DDR4, and SDRAM

HDD is a traditional storage device that uses spinning disks to store data, while SSD uses flash memory for faster access.

• HDD is slower and more prone to mechanical failure than SSD

• SSD is more expensive but offers faster read/write speeds

• SSD is more durable and consumes less power than HDD

• HDD is still commonly used for large storage needs, while SSD is preferred for faster performance

• Examples of SSDs include Samsung 97...read more
