E Correct answer
Explanation

Correct answer. NetPath is a manually curated resource of human signal transduction pathways. Reactome is a navigable map of human biological pathways, ranging from metabolic processes (metabolic pathways) to hormonal signalling (signal transduction pathways).

  2. SYSID

  3. Process ID

  4. IP address

For which of the following is a proxy server is used?

  1. To provide security against unauthorised users

  2. To process client requests for web pages

  3. To process client requests for database access

  4. To provide TCP/IP

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A proxy server primarily acts as an intermediary for client requests, processing requests for web pages and returning cached or fresh content. While proxies can provide security features, their fundamental purpose is handling client requests for web resources, not TCP/IP provision or database access.

Multiple choice

This is a standard way for a Web server to pass a Web user's request to an application program and to receive data back to forward to the user

  1. interrupt request

  2. forward DNS lookup

  3. data link layer

  4. file transfer protocol

  5. common gateway interface
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

CGI (Common Gateway Interface) is the standard protocol for web servers to pass user requests to application programs and return data to the user. It enables dynamic content generation by allowing web servers to communicate with external applications that process requests and generate responses.

Multiple choice

When a host knows its physical address but not its IP address, which protocol is used?

  1. ICMP

  2. IGMP

  3. ARP

  4. RARP
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

RARP stands for Reverse Address Resolution Protocol. It finds the logical address for a machine that knows only its physical address.One or more unique logical (IP) address is assigned to host or router and this address is independent from the physical (hardware) address of the machine because it knows the physical address, but not its IP adress, so this is the correct answer.
