Q: 3In GSM Architecture, which of the following stores the local copy of the data from the HLR?
Option B
In GSM architecture, the Home Location Register (HLR) is a central database that stores permanent subscriber information, such as the subscriber’s profile, services, and current location. When a subscriber roams into a new area, the Visitor Location Register (VLR) temporarily stores a local copy of the subscriber’s data from the HLR.
Q: 4Ethernet card is also known as—
Option B
An Ethernet card is also commonly known as a Network Interface Card (NIC). It is a hardware component that allows a computer to connect to a network, usually a Local Area Network (LAN), using Ethernet technology.
The unique ID of a NIC on the Ethernet network is called its MAC (Media Access Control) address. The MAC address is a 48-bit (6 bytes) hexadecimal number, usually written in six pairs of hexadecimal digits separated by colons or hyphens, for example:
00:1A:2B:3C:4D:5E
Q: 5The correct statement regarding WiFi and Wi-Max technology is/are-
(I) WiFi uses radio waves to create wireless connection, WiMax uses spectrum to deliver connection.
(II) WiFi is defined under IEEE 802.11x standards, while WiMax is defined under IEEE 803.16y standards.
(III) WiMax covers comparatively larger area than WiFi.
Option C
WiFi and WiMAX are two popular wireless communication technologies, but they differ in coverage and standards. WiFi, based on the IEEE 802.11 family of standards, is mainly used for creating local area wireless networks with coverage typically up to 100 meters.
On the other hand, WiMAX is defined under the IEEE 802.16 standard and is designed for broadband wireless access over much larger distances, covering up to several kilometers.
The IEEE stands for Institute of Electrical and Electronics Engineers. IEEE develops global standards and supports a large community of engineers and scientists worldwide.
Q: 6What is the term used for the word or phrase entered in the search box of a search engine?
Option A
When you type a word or phrase into the search box of a search engine like Google or Bing, that input is called search query or more commonly keywords. The search engine uses these keywords to find and display relevant results from its database.
| TERM | DESCRIPTION |
|---|---|
| Keyword | A word or phrase entered into a search engine to find relevant information. Example: typing “rssb computer question solution” in Google search. |
| Web Address (URL) | The unique address used to access a specific web page on the internet. Example: https://www.surakuacademy.com |
| Homepage | The main or starting page of a website, usually the first page you see when visiting a domain. It acts as the entry point to the rest of the site. Example: Suraku Academy homepage. |
Q: 7GSM technology is combination of _____________.
Option A
GSM (Global System for Mobile Communications) is a digital cellular technology that combines multiple access techniques to efficiently use the available radio spectrum.
GSM uses Frequency Division Multiple Access (FDMA) to divide the available frequency bands into separate channels, and Time Division Multiple Access (TDMA) to divide each frequency channel into time slots that can be shared by multiple users.
Q: 8What is the full form of FTP in computer terminology?
Option A
FTP stands for File Transfer Protocol. It is a standard network protocol used to transfer files between a client and a server over a network. FTP allows users to upload, download, rename, delete, and manage files on remote servers efficiently.
| PROTOCOL | FULL FORM | DESCRIPTION |
|---|---|---|
| DNS | Domain Name System | Translates domain names (like surakuacademy.com) into IP addresses. |
| IP | Internet Protocol | Provides addressing system for devices on a network. |
| HTTP | Hypertext Transfer Protocol | Used for accessing web pages on the internet. |
| HTTPS | Hypertext Transfer Protocol Secure | Secure version of HTTP with encryption (SSL/TLS). |
| SMTP | Simple Mail Transfer Protocol | Used for sending emails. |
| IMAP | Internet Message Access Protocol | Used for retrieving emails while keeping them on the server. |
| POP3 | Post Office Protocol Version 3 | Used for retrieving emails by downloading them to the device. |
| TCP | Transmission Control Protocol | Ensures reliable, ordered, and error-checked delivery of data. |
| UDP | User Datagram Protocol | Faster but less reliable data transfer. Generally used in video streaming, games. |
Q: 9In Wi-Fi security, which of the following protocol is more used?
Option B
WPA2 (Wi-Fi Protected Access 2) is the most widely used Wi-Fi security protocol. It was introduced in 2004 and uses AES (Advanced Encryption Standard) for strong encryption and security.
Q: 10HTTPS uses __________ port number.
Option C
HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP, which is used for communication between a web browser and a web server.
Unlike regular HTTP, HTTPS provides encryption and security using the SSL (Secure Sockets Layer) or TLS (Transport Layer Security) protocols. This ensures that any data exchanged, such as passwords, card details, or personal details is protected from unauthorized access.
Every network service on the internet uses a specific port number to communicate. By default, HTTP uses port 80, while HTTPs uses port 443.
