There are two parts.
1st part is basic CS knowledge(can be found on glassdoor), 2nd part is one
coding question(Reverse Words in a String problem from leetcode).鐣欏璁哄潧-涓浜-涓夊垎鍦


1st part questions and answers:
#############################################
2. No. of bytes in a 64 bit machine
Number of bytes to code 64 bits?
8


3. What is the value of the unsigned integer in a 32 bit machine? Maximum value of 32 bits unsigned int?
unsigned int        4bytes        0 to 4294967295(2^32 - 1)
two to the power of 32 minus one. from: 1point3acres.com/bbs
http://www.tutorialspoint.com/cplusplus/cpp_data_types.htm


4. How many bits are required to represent an octal digit?
- Number of digits needed to code an octet?

5. Where can you apply binary search - sorted array or linked list?

6. Time complexity of binary search.
O(logn). from: 1point3acres.com/bbs

O(1)


8. What is the signal number for kill
http://meinit.nl/the-3-most-important-kill-signals-on-the-linux-unix-command-line.1point3acres缃


Most Linux or UNIX users know that there is a kill(1) command to stop processes, but what are the options, what do they mean?


These options are called signals, which can be expressed in either numbers or words. Some known once are "-1" or "-HUP". Also well known is "-9" (aka "-KILL").鐣欏璁哄潧-涓浜-涓夊垎鍦

9. How would you find a method in a file.
find . -name '*.cpp' | xargs grep XXX

. 涓浜-涓夊垎-鍦帮紝鐙鍙戝竷

10. How would you find whether a remote computer is online or not
ping IP/domain name. 鐗涗汉浜戦泦,涓浜╀笁鍒嗗湴


11. How does the domain name map to ip address. 鍥磋鎴戜滑@1point 3 acres
http://www.firewall.cx/networking-topics/protocols/domain-name-system-dns.html


DNS is a very popular and well known protocol. It is used for resolving host names and domain names to IP addresses. The fact is that when you type www.firewall.cx the name is translated into an IP address via a number of queries that take place from your PC towards the DNS server. This DNS Query process (and more) is analysed in great depth in the articles that follow.


12. How to select one row of a table in SQL

13. Port number for HTTP and protocol used by HTTP
80 TCP/IP ?
http://searchnetworking.techtarget.com/answer/How-are-TCP-IP-and-HTTP-related
http://www.firewall.cx/networking-topics/protocols.html. 1point3acres.com/bbs


HTTP is an application layer protocol designed within the framework of the Internet Protocol Suite. Its definition presumes an underlying and reliable transport layer protocol,[3] and Transmission Control Protocol (TCP) is commonly used. However HTTP can use unreliable protocols such as the User Datagram Protocol (UDP), for example in Simple Service Discovery Protocol (SSDP).


14. Full form of SSL and what does it do?   
SSL stands for Secure Socket Layer. The protocol's name is now officially TLS but we will continue to use SSL since that's the better known name.
.1point3acres缃
. Waral 鍗氬鏈夋洿澶氭枃绔,
SSL was designed to permit web browsers and web servers to exchange sensitive information and prevent programs that could view the network traffic from reading the sensitive data.

- What is the Linux kill signal?
- Command to highlight the occurrence of a method in a file?
- Would you apply a binary search on a linked list or a sorted array?


- Is an inner join an intersection, a union or something else?
Inner join - An inner join using either of the equivalent queries gives the intersection of the two tables, i.e. the two rows they have in common.
Left outer join - A left outer join will give all rows in A, plus any common rows in B.
Full outer join - A full outer join will give you the union of A and B, i.e. All the rows in A and all the rows in B. If something in A doesn't have a corresponding datum in B, then the B portion is null, and vice versa.
