Right Answer:
Network tools are software or hardware utilities used to manage, monitor, and troubleshoot network connections. Common network tools include:

1. **Ping** - Tests connectivity between devices.
2. **Traceroute** - Shows the path data takes to reach a destination.
3. **IPconfig/ifconfig** - Displays network configuration details.
4. **Netstat** - Shows active connections and listening ports.
5. **Nslookup** - Queries DNS to obtain domain name or IP address information.
6. **Wireshark** - Captures and analyzes network traffic.
7. **Nmap** - Scans networks to discover devices and services.

These tools help network administrators ensure the network is functioning properly and diagnose issues when they arise.

Right Answer:
To work for GSM, you need to understand its architecture, including the Mobile Station (MS), Base Station Subsystem (BSS), Network and Switching Subsystem (NSS), and Operation Support Subsystem (OSS). Familiarize yourself with the signaling protocols like MAP and RANAP, and learn about frequency allocation, handover procedures, and network optimization techniques. Additionally, knowledge of RF principles, troubleshooting, and maintenance of GSM equipment is essential.

Right Answer:
Manual testing involves human testers executing test cases without automation tools, while automation testing uses software tools to run tests automatically, increasing efficiency and repeatability.

Right Answer:
In networking, advertisement refers to the process of announcing routes or network information to other routers or devices. This is commonly done using protocols like BGP (Border Gateway Protocol) or OSPF (Open Shortest Path First) to inform other network nodes about available paths and their attributes, enabling efficient data routing.

Right Answer:
Networking refers to the practice of connecting computers and other devices together to share resources, communicate, and exchange data.

Right Answer:
I am open to both part-time and full-time positions, depending on the needs of the company.

Right Answer:
I chose BPO because it offers opportunities for growth, enhances my communication skills, and allows me to work in a dynamic environment while helping customers.

Right Answer:

1. **Installation of OS:**
- Insert the OS installation media (USB/DVD) into the PC.
- Restart the PC and enter the BIOS/UEFI settings (usually by pressing F2, F10, DEL, or ESC).
- Set the boot order to prioritize the installation media.
- Save changes and exit BIOS/UEFI.
- Follow the on-screen instructions to select language, time, and keyboard preferences.
- Choose "Install Now" and enter the product key if prompted.
- Select the installation type (Upgrade or Custom) and choose the partition to install the OS.
- Wait for the installation to complete, then set up user accounts and preferences.

2. **Installation of MS Office:**
- Download the MS Office installer from the official Microsoft website or insert the installation media.
- Run the installer and follow the prompts.

Right Answer:
Telemarketing is the process of selling products or services directly to customers over the phone.

Right Answer:
GSM (Global System for Mobile Communications) network architecture consists of three main components:

1. **Mobile Station (MS)**: The user's device, including the mobile phone and SIM card.
2. **Base Station Subsystem (BSS)**: Comprises the Base Transceiver Station (BTS) and Base Station Controller (BSC) that manage radio communication with mobile devices.
3. **Network and Switching Subsystem (NSS)**: Includes the Mobile Switching Center (MSC), which connects calls and manages mobility, along with databases like the Home Location Register (HLR) and Visitor Location Register (VLR).
4. **Operation Support Subsystem (OSS)**: Manages network operations and maintenance.

The protocol architecture includes:

1. **Layer 1 (Physical Layer)**: Handles the transmission of raw bitstreams over the physical medium.
2. **Layer 2 (Data Link Layer)**: Manages error correction and framing, including the Logical Link Control (LLC)

Right Answer:
