RSMSSB Computor common mistakes
RSMSSB Computor · Understand the traps and how to avoid them.
Treating 'RAM' and 'ROM' as interchangeable in questions about primary memory, and selecting 'RAM is non-volatile' or 'ROM is volatile' as true.
Everyday language calls any computer memory 'memory', and candidates memorize the acronyms without linking them to the volatility property that the exam tests. The exam repeatedly asks which memory loses data on power-off.
What to do instead
Build a two-column table: volatile (RAM, cache, registers) vs non-volatile (ROM, flash, HDD, SSD). For each, write one example use. Recite the rule 'RAM forgets, ROM remembers' before answering any memory question, and check whether the question asks about primary or secondary storage.
Confusing input, output, and storage devices when classifying hardware, e.g. labelling a touchscreen only as output, a pen drive as input, or a scanner as output.
Modern devices are multifunction, so candidates rely on the device's most familiar use rather than the direction of data flow the exam expects. The exam uses classic single-function categories.
What to do instead
Classify by data direction: into the computer = input (keyboard, mouse, scanner, mic, webcam); out of the computer = output (monitor, printer, speaker, projector); retained for later = storage (HDD, SSD, pen drive, CD). For hybrids like touchscreen, state 'both input and output' and note the direction explicitly.
Mixing up IP address, MAC address, and port number, or claiming an IP address identifies a specific physical machine permanently.
All three appear in networking questions and candidates memorize them as 'addresses' without attaching the layer and purpose. DHCP and NAT make IP addresses change, which contradicts the 'permanent' intuition.
What to do instead
Memorize one line each: MAC = 48-bit hardware address burned into the NIC, used on the local link; IP = logical address assigned to a device on a network, can change via DHCP; port = identifies a service/process on a host (e.g. 80 HTTP, 443 HTTPS, 25 SMTP, 53 DNS). When a question says 'physical address', answer MAC; 'logical address', answer IP.
Choosing the wrong spreadsheet formula or misreading relative vs absolute references, e.g. writing =SUM(A1:A5) when the question asks for a count, or copying =A1*B1 and expecting the same cell to be used in every row.
Candidates recognize the function name but not its exact output, and they forget that copying a formula shifts relative references unless $ is used. The exam tests the difference directly.
What to do instead
Learn the core functions with one example each: SUM adds, COUNT counts numbers, COUNTA counts non-empty cells, AVERAGE means, MAX/MIN extremes, IF conditional. Drill the $ rule: $A$1 locks both column and row, A$1 locks row, $A1 locks column. Before answering, ask 'what does this function return, and what happens when the formula is copied?'
Confusing Save with Save As, or not knowing which file format preserves formatting versus which is plain text, leading to wrong answers about document handling.
Both commands sound similar and candidates have used them casually without noticing the difference in behaviour. Exam questions test the consequence (overwrite vs new file, formatting loss).
What to do instead
Memorize: Save overwrites the current file in its current format; Save As creates a new file or changes format/location. For formats, know .docx/.odt keep formatting, .txt is plain text with no formatting, .pdf is fixed-layout for sharing, .csv is comma-separated plain data for spreadsheets. Match the question's goal to the format property.
Answering Rajasthan geography or culture questions from general North India knowledge, e.g. naming the wrong longest river, wrong state animal, or wrong folk dance region.
Rajasthan has distinctive facts that differ from neighbouring states, and candidates study general Indian GK instead of state-specific lists. The exam rewards precise state facts.
What to do instead
Make a one-page Rajasthan fact sheet and revise it daily: capital Jaipur; state animal chinkara (and camel as state animal livestock); state bird godawan (great Indian bustard); state tree khejri; longest river within the state is the Chambal (Banas is the longest river flowing entirely within Rajasthan); Aravalli as the oldest mountain range; Thar desert in the west. Group folk dances by region (ghoomar, kalbelia, gair, chakri) and attach each to its community or festival.
Mixing up Rajasthan's historical dynasties, founding dates, or administrative divisions, such as attributing Jaipur's founding to the wrong ruler or confusing the number of divisions and districts.
Rajasthan history is dense with similar-sounding rulers and shifting administrative boundaries, and candidates memorize names without anchors. Recent district reorganizations make older study material misleading.
What to do instead
Anchor each fact to a person, place, and year: Jaipur founded by Sawai Jai Singh II in 1727; Udaipur by Maharana Udai Singh II in 1559; Jodhpur by Rao Jodha in 1459. For administration, verify the current number of divisions and districts from the official Rajasthan government source rather than a coaching PDF, and note the date of any reorganization you rely on.
Confusing Hindi grammatical categories in objective questions, e.g. misidentifying sandhi type, samas type, or treating a tatsam word as tadbhav.
Hindi grammar terminology overlaps in sound (sandhi vs samas, tatsam vs tadbhav) and candidates learn definitions without practising identification on single words. Objective format removes context that would otherwise help.
What to do instead
Practise identification, not definitions: for sandhi, split the word and name the change (swar sandhi when vowels combine, vyanjan when a consonant is inserted, visarg when visarga changes). For samas, ask which word lost its ending and what relation remains (tatpurush, dwandwa, bahuvrihi, karmadharaya, dwigu, avyayibhav). For tatsam/tadbhav, check whether the word is unchanged from Sanskrit (tatsam) or evolved (tadbhav). Do 20 split-the-word drills per topic.
Answering English grammar items by ear and missing the tested rule, e.g. choosing 'He go' corrections without checking subject-verb agreement, or misidentifying the passive voice or the correct preposition.
Spoken fluency does not equal rule accuracy, and exam items isolate one rule at a time. Candidates pick the option that sounds natural rather than the one that satisfies the rule.
What to do instead
For each grammar item, name the rule before choosing: subject-verb agreement (singular subject takes singular verb), tense consistency, article use (a/an by sound, the for specific), preposition collocation (depend on, good at, married to), voice (passive = be + past participle). Read the full sentence with each option substituted and reject options that break the named rule.
Running out of time or losing marks on data-entry and office-automation practical items because of slow typing, wrong shortcut recall, or not checking the entry against the source.
Data entry is scored on speed and accuracy together, and candidates practise speed without accuracy checks. Shortcut questions also punish guessing because Ctrl+S, Ctrl+P, and Ctrl+Shift+S do different things.
What to do instead
Train with a timer: 10-minute typing drills targeting at least 30–35 words per minute with under 2% errors, and after each drill compare your output to the source line by line. Memorize the high-frequency shortcuts (Ctrl+C copy, Ctrl+X cut, Ctrl+V paste, Ctrl+Z undo, Ctrl+Y redo, Ctrl+S save, Ctrl+P print, Ctrl+F find, Ctrl+A select all) and quiz yourself until recall is automatic. In the exam, enter data in small blocks and verify each block before moving on.
