File Systems: Essential Concepts and Operations
Essential Conditions for Long-Term Information Storage
The essential conditions for the storage of long-term information are:
- It should be possible to store a large amount of information.
- The information must survive the completion of the process that uses it.
- It should be possible that several concurrent processes access the information.
The Solution: Files on External Media
The solution is to store information on disks and other external media in units called files:
- Files should be persistent, i.e.,
Routing Algorithms, FTP, and CSMA Protocols Explained
Distance Vector Routing Algorithm
The Distance Vector algorithm is a distributed routing algorithm where routers share their routing table information with their immediate neighbors periodically. It is based on the Bellman-Ford algorithm.
Key Features
- Vector of Distances: Each router maintains a table (vector) of distances to all other nodes in the network. Distance is typically measured in terms of hop count or other metrics like delay or cost.
- Periodic Updates: Routers exchange their routing tables

SDH and PDH Networks: Characteristics and Differences
1. Indicate the Correct Statement Regarding PDH Networks
- PDH networks are limited to carrying voice signals.
- In PDH networks, multiplexing is performed bitwise.
- PDH networks have different hierarchies in Bolivia, the USA, and Japan.
- A PDH network is based on synchronous multiplexers.
2. Which of the Following Policies Defines the Signal Format?
None of the above. (The correct answer would likely involve a standard like G.703, not G.708)
